Exposure of male Albino Swiss rats to the nonsteroidal antiandrogen flutamide during the period from gestational day (d) 10 to birth resulted in feminisation of the external genitalia and the suppression of growth of the male reproductive tract. In adulthood, testes were found to be located in diverse positions. True cryptorchidism occurred in 10% of cases, whereas 50% of testes descended to the scrotum and 40% were located in a suprainguinal ectopic region. Varying degrees of tubule abnormality were seen in the testes of flutamide-treated animals, ranging from completely normal tubules with full spermatogenesis (and the expected frequency of the stages of spermatogenesis) to severely abnormal tubules lined with Sertoli cells only. For each individual testis, the overall severity of tubule damage was strongly correlated with its adult location, with intra-abdominal testes worst affected and scrotally-located testes least; only the latter contained normal tubules. Similarly, intra-abdominal testes were the smallest in weight and contained the least testosterone. By contrast, postnatal treatment of male rats with flutamide from birth to postnatal d 14 did not impair development of the external genitalia, the process of testicular descent or adult spermatogenesis. These findings confirm that androgen blockade during embryonic development interferes with testicular descent but also demonstrate that (1) prenatal flutamide treatment per se has a detrimental effect on adult testis morphology but (2) the degree of abnormality of the testes is strongly influenced by location.

Identification of aberrant expression patterns of genes in prostate cancer (PCa) is a key step towards the development of effective therapies. Prostate-specific antigen (PSA) levels are commonly measured for the early detection of PCa, but which itself is still not an ideal biomarker. We analysed the expression patterns of prostate cancer susceptibility candidate (PRAC) in prostate cancer. The PRAC gene is known to be commonly expressed in prostate tissue, rectum and colon. To provide clear insights into the expression patterns of PRAC in PCa, we examined the gene expression by quantitative real-time PCR (qRT-PCR), western blot analysis and immunohistochemistry (IHC). The results showed that PRAC expression levels in androgen‑insensitive cells (DU145 and PC3) are lower than those in androgen-sensitive cell lines (LNCaP, LNCaP-R and CW22R). However, treatment of the LNCaP cell line with androgen and anti-androgen demonstrated that PRAC is expressed in an androgen-independent manner. Further, PRAC expression was restored upon treatment of DU145 and PC3 cells with the methyltransferase inhibitor, 5-aza-2'-deoxycytidine (5-aza-CdR), which indicates the effect of methylation in the control of PRAC expression. In addition, IHC analysis revealed a significantly decreased immunoreactivity of PRAC protein in PCa tissues compared to benign prostatic hyperplasia (BPH) (p<0.0001). Thus, our findings suggest that the pathogenesis of PCa may be due to the expression levels of PRAC protein, and this protein can serve as a potential biomarker for the management of PCa.

We could not expect more than 50% cases to show the down grading and down staging. But, in T 3 case, surgical failure could be decrease. We could expect prostate cancer cases without positive bcl-2 cells, p 53 over expression and Gleason 4 x 5 to reveal the good histological effects of neoadjuvant CAB therapy.

In a multicenter trial conducted by the Danish Prostatic Cancer Group, 264 patients with advanced prostate cancer were randomized either to undergo bilateral orchiectomy or to receive combination treatment with goserelin acetate and flutamide. This report is an update of that study, covering a median follow-up for survival of 57 months. Of 262 patients who were evaluated, 208 have died. As noted in earlier analyses of this study, no differences in time to progression and cause-specific and overall survival could be identified between the two treatment groups. In conclusion, the combination of goserelin and flutamide was not clinically superior to bilateral orchiectomy in the treatment of advanced prostate cancer.

A prior comparison of 750 mg flutamide daily to 500 mg daily with an LHRH analog or orchiectomy showed no difference in effect on prostate specific antigen (PSA). However, any difference was likely masked by hypogonadism from concomitant LHRH analog or orchiectomy. We sought to evaluate different flutamide dosing schedules without this confounding factor. We recruited 50 men with advanced prostate cancer who elected to receive hormonal therapy to be randomized to 1 of 3 flutamide treatment groups: 1) 250 mg once daily, 2) 250 mg twice daily, or 3) 250 mg 3 times daily for 3 months, after which the therapy of their choice was instituted. Serum samples at the initiation of therapy and at the 1- and 3-month time point were assessed for PSA, testosterone, liver function tests, hematology, and renal function. Prostate volume, androgen deficiency symptoms, and a compliance diary were also recorded. Testosterone and PSA levels show a dose-dependent response to flutamide monotherapy. Loss of libido and erectile dysfunction occurred in all 3 treatment groups, with a trend toward worsening sexual function with higher flutamide dosing, but this trend did not reach statistical significance. Prostate volumes decreased by an average of 34.3% in the patients receiving 250 mg flutamide 3 times daily, 27.8% in patients receiving 250 mg flutamide twice daily, and 19.2% in those receiving a once daily dose of 250 mg flutamide. There was a significant difference between the once daily group and the 3 times daily group (P =.047). Flutamide at 500 mg did not result in significant changes in testosterone, PSA, prostate volume, or androgen deficiency symptoms compared to 750 mg daily after 3 months.

Significant changes of the aromatase and 5 alpha-reductase hypothalamic activity were found in juvenile prenatally stressed male Wistar rats. The blood plasma testosterone level increased following niftolide (NF) or 1, 4, 6-androstatine-3, 17-dione (ATD) administration. Prenatal stress seems to exert a modifying effect upon the regulating mechanisms of the pituitary gonadotropin function, lowering the functional reserves of the hypothalamo-hypophyseal-testicular axis in pre- and postpubertal male rats.

Hirsutism can be evaluated with a detailed history and physical examination and a limited number of hormonal tests. Serious disorders presenting as hirsutism are rare and can be excluded with the recommended evaluation. Treatment is targeted at reducing the production and bioavailability of testosterone, as well as blocking target tissue androgen action.

The toxicity rates of 480 consecutive prostate cancer patients were reviewed and compared using the chi2 test. Ordered logit regression analyses were performed including the major demographic, disease, and treatment factors. Although no reduction in acute GI toxicity from HT use was observed (P=0.067), a lower rate of acute GU toxicity was observed (P=0.002). No factor reached statistical significance on regression analysis.

In the pathogenesis of acne, androgen hormones play a crucial role. In the treatment of acne, hormonal therapies provide valuable alternatives to standard modalities in selected women. Although numerous factors contribute to the development of acne, the requirement for androgens is absolute and is one that allows for effective treatments in women through inhibition of androgen expression. The two prerequisites for androgen expression at the level of the pilosebaceous unit are the presence of androgen in the form of either testosterone or dihydrotestosterone; and functioning androgen receptors. A third component may be the metabolism of androgen precursors to active androgens within pilosebaceous units. Hormonal treatment of hyperandrogenism (acne, hirsutism, androgenetic alopecia) such as that seen in polycystic ovary syndrome, centers on reduction of circulating androgen levels and androgen receptor blockade. Combination oral contraceptives represent the primary treatment modality for reducing circulating androgens from ovarian and, to a lesser degree, adrenal sources. Newer formulations may also have clinically significant androgen receptor blocking and 5alpha-reductase inhibiting effects. Newer oral contraceptives have high safety profiles and are used widely internationally for this purpose. Androgen receptor blockers currently in use include spironolactone, cyproterone acetate, and flutamide. Androgen receptor blockers are frequently combined with oral contraceptives to achieve optimal results in selected women. In women with adrenal hyperplasia, low-dose corticosteroids may be added to reduce adrenal androgen precursors. Inhibition of enzymes of androgen metabolism in the pilosebaceous unit remain largely investigational in the treatment of acne, although the benefit of 5alpha-reductase (type 2) inhibition is established in androgenetic alopecia in men. This article reviews the essentials of hormonal influence in acne pathogenesis, discusses the hormonal therapies most utilized in the treatment of acne, and the pre-treatment evaluation of women in whom hormonal therapies are being considered.

Five cases of juvenile nasopharyngeal angiofibroma were studied in terms of the presence of progesterone, estradiol, testosterone, and dihydrotestosterone in the juvenile nasopharyngeal angiofibroma tissue using the peroxidase-antiperoxidase method. Progesterone and estradiol were positive in all cases. Testosterone was positive in 2 of the 5 patients. Dihydrotestosterone was positive in 3 of the 5 patients. Hormone in the juvenile nasopharyngeal angiofibroma tissue seems to change by the activity of nasopharyngeal angiofibroma.

The median follow-up period was 16.9 months. Therapy failed in 1 patient with Stage D2 disease at 12 months, but an additional response to subsequent LHRH agonist therapy was observed. One patient developed National Cancer Institute grade 3 diarrhea and was withdrawn from the study. Seven of 20 men developed mild gynecomastia, and 3 of 20 developed mild transient liver function test elevations. Mean PSA levels were 94.6 +/- 38.2 ng/mL at baseline and 7.8 +/- 2.7 and 4.7 +/- 2.2 ng/mL at the first and second PSA nadir values, respectively (P = 0.034). Mean percent decline in PSA value from baseline was 87.0 +/- 3.1% with flutamide alone and 94.0 +/- 1.9% with both flutamide and finasteride (P = 0.001). Eleven of 20 men were potent at baseline. At the second nadir PSA value, 9 (82%) of 11 were potent, whereas 2 (18%) of 11 were impotent. With longer follow-up (median 16.4 months), 6 (55%) of 11 men were potent, 2 (18%) of 11 were partially potent, and 3 (27%) of 11 were impotent. With flutamide alone, testosterone rose a mean of 77 +/- 14.7% of baseline (P = 0.0001), DHEA fell a mean of 32.4 +/- 4.6% (P = 0.0001), and DHT was unchanged. With the addition of finasteride, testosterone rose another 14 +/- 6% (P = 0.06, not significant), DHEA was unchanged, and DHT fell a mean of 34.8 +/- 4.7% (P = 0.0009).

We investigated the ability of a mixture of three androgen receptor antagonists to induce disruption of male sexual differentiation after perinatal exposure. The aim was to assess whether the joint effects of vinclozolin, flutamide, and procymidone can be predicted based on dose-response data of the individual chemicals. Chemicals were administered orally to pregnant Wistar rats from gestational day 7 to postnatal day 16. Changes in reproductive organ weights and of androgen-regulated gene expression in prostates from male rat pups were chosen as end points for extensive dose-response studies. With all end points, the joint effects of the three antiandrogens were dose additive. Histological evaluations showed that dysgenesis and hypoplasia of prostates, seminal vesicles, and epididymis were seen with the highest mixture doses. No changes were observed in any single-compound low-dose group for these lesions, nor were there histopathological changes in the testes. Pronounced dysgenesis of external genitals was observed with all doses of the mixture, and severe dysgenesis was seen with a mixture for which the individual compounds caused no effects. A combination of doses of each chemical that on its own did not produce significant reductions in the weights of seminal vesicles and PBP C3 expression induced a marked mixture effect. Thus, antiandrogens cause additive effects on end points of various molecular complexities such as alterations at the morphological and the molecular level. Exposure to antiandrogens, which appears to exert only small effects when judged on a chemical-by-chemical basis, may induce marked responses in concert with, possibly unrecognized, similarly acting chemicals.

The study enrolled 35 young women with acne and irsutism; 31 had polycystic ovary syndrome (PCOS) and 4 periferic iperandrogenism. In other 8 young women, sexually active, the flutamide has been associated with the hormonal contraceptive. On the three young women with iperinsulinism it has been decided to associate the flutamide with the metformina. All the young women were checked each month for the liver functional. Before the beginning of the therapy the menstrual situation, the Body Mass Index (BMI), the Ferriman' s and Cremoncini's score, the ovary's ultrasound aspect, and the hormonal order were evaluated. Follow-up was made after three months and after six months after the beginning of the therapy with flutamide 62.5 mg/die.

Flutamide, a widely used nonsteroidal antiandrogen drug for the treatment of prostate cancer, has been associated with rare incidences of hepatotoxicity in patients. It is believed that bioactivation of flutamide and subsequent covalent binding to cellular proteins is responsible for its toxicity. A novel N-S glutathione adduct has been identified in a previous bioactivation study of flutamide (Kang et al., 2007). Due to the extensive first pass metabolism, flutamide metabolites such as 2-hydroxyflutamide and 4-nitro-3-(trifluoromethyl)phenylamine (Flu-1) have achieved plasma concentrations higher than the parent in prostate cancer patients. In vitro studies in human liver microsomes were conducted to probe the cytochrome P450 (P450)-mediated bioactivation of flutamide metabolites and identify the possible reactive species using reduced glutathione (GSH) as a trapping agent. Several GSH adducts (G1, Flu-1-G1, Flu-1-G2, Flu-6-Gs) derived from the metabolites of flutamide were identified and characterized. A comprehensive bioactivation mechanism was proposed to account for the formation of the observed GSH adducts. Of interest were the formation of a reactive intermediate by the desaturation of the isopropyl group of M5 and the unusual bioactivation of Flu-1. Studies using recombinant P450s suggested that the major P450 isozymes involved in the bioactivation of flutamide and its metabolites were CYP1A2, CYP3A4, and CYP2C19. These findings suggested that, in addition to the direct bioactivation of flutamide, the metabolites of flutamide could also be bioactivated and contribute to flutamide-induced hepatotoxicity.

Twenty-six patients with prostate cancer and elevated serum levels of PSA were randomly assigned to 5 groups. Group A patients (n = 6) were treated with a subcutaneous injection of 3.75 mg leuprorelin acetate depot alone. Group B, C, D and E patients (5 patients in each group) were treated with 375 mg/day of orally administered flutamide combined with leuprorelin. Flutamide was initiated on the day of leuprorelin injection in group B, and at 1, 2 and 4 weeks before leuprorelin injection in groups C, D and E, respectively. Serum PSA and testosterone levels were measured in each patient.

Sulfated glycoprotein-2 (SGP-2) is secreted in Sertoli cells and epididymal epithelial cells and plays important roles in the regulation of spermatogenesis and sperm maturation. To investigate whether endocrine disruptors affect spermatogenesis through an SGP-2-dependent mechanism, daily oral doses of testosterone (50, 200 and 1,000 microg/kg), flutamide (1, 5 and 25 mg/kg), ketoconazole (0.2, 1, 5 and 25 buy eulexin online mg/kg), diethylhexylphthalate (10, 50 and 250 mg/kg), nonylphenol (10, 50, 100 and 250 mg/kg), octylphenol (10, 50 and 250 mg/kg), diethylstilbesterol (10, 20 and 40 microg/kg) or corn oil (control) were administered to 5 week-old, male Sprague-Dawley rats for 3 weeks. Following treatment with these endocrine disruptors, testicular expression of SGP-2 mRNA was analyzed using reverse transcription-polymerase chain reaction. Compared with the control, the lowest dose of testosterone (50 microg/kg/day) significantly increased expression of SGP-2 mRNA, whereas 200 and 1,000 microg/kg/day testosterone significantly decreased the expression (P<0.05). Flutamide, ketoconazole, diethylhexylphthalate, nonylphenol, octylphenol and diethylstilbesterol significantly decreased SGP-2 mRNA expression in testes at all doses studied, with the exception of 1 mg/kg/day flutamide (P<0.05). These results suggest that endocrine disruptors might decrease spermatogenesis in testes by decreasing expression of SGP-2 mRNA.

A yeast genetic screening was developed to isolate androgen receptor (AR) mutants with divergent transactivation characteristics in response to hydroxyflutamide (HF), an active metabolite of flutamide used for prostate cancer treatment. Two mutants carrying the substitution C685Y or E708K were isolated and characterized. Substitution of C685Y for wild-type AR (wtAR) buy eulexin online rendered the receptor supersensitive to androgenic activity from HF and female hormones such as 17beta-estradiol (E2) and progesterone (P). Similar effects were observed in the AR mutant, named T876AAR, isolated from LNCaP cells. Surprisingly, we found that C685YAR7, but not T876AAR7, could be activated by casodex (bicalutamide), a nonsteroidal pure antiandrogen, with an induction fold 3- to 5-fold times higher than that for wild type or T876AAR. By contrast, although replacement of E708K for wtAR showed little effect on dihydrotestosterone-mediated transactivation, E708KAR lost its transcriptional response from many other ligands. The effects of ligands on E708KAR could be controlled at the DNA-binding level owing to the finding of a significant decrease in the DNA-binding ability once E708KAR was bound to HF, E2, or P. Together, these results suggest that C685YAR can be a novel tool for assaying the androgenic activity from antiandrogens, and the mechanism revealed from E708KAR could provide a possible explanation for the partial androgen insensitivity syndrome in men with a natural E708KAR mutation.

The growth and development of prostate gland is governed by testosterone. Testosterone helps in maintaining the adipose tissue stores of the body. It is well documented that with advancing age there has been a gradual decline in testosterone levels. Our aim was to study the protective role of daidzein on flutamide-induced androgen deprivation on matrix degrading genes, lipid profile and oxidative stress in Wistar rats. Sub-chronic (60 days) flutamide (30 mg/kg b.wt) administration resulted buy eulexin online in marked increase in expressions of matrix degrading genes [matrix metalloproteases 9 and urokinase plasminogen activation receptor]. Additionally, it increased the levels of low density lipoproteins, total cholesterol, triglycerides, and lowered the levels of high density lipoproteins and endogenous antioxidant levels. Oral administration of daidzein (20 and 60 mg/kg b.wt) restituted the levels to normal. Daidzein administration resulted in amelioration of the prostate atrophy, degeneracy and invasiveness induced by flutamide. Our findings suggest that the daidzein may be given as dietary supplement to patients who are on androgen deprivation therapy, to minimize the adverse effects related to it and also retarding susceptibility of patients to cardiovascular diseases.

Antiandrogens inhibit the ligand-induced transactivation by the androgen receptor (AR) and have a widespread use in the treatment of prostate cancer but their mode of action is not fully understood. Here we show that the ability of the antiandrogen cyproterone acetate (CPA) to inhibit transactivation by the human AR (hAR) involves the corepressor SMRT (silencing mediator for retinoic acid and thyroid hormone receptor). We detect binding of SMRT to hAR when treating with the antiandrogen CPA, but not with the antihormones casodex or hydroxyflutamide. Interestingly, we find that SMRT binds to the N terminus of buy eulexin online the hAR. Thereby, SMRT modulates the activity of hAR in receptor-negative CV1 cells. In addition, we have used receptor point mutants that exhibit normal transactivation potential and unchanged partial agonistic activity when treated with CPA, but lack both SMRT binding and SMRT-mediated inhibition of CPA-bound AR. This indicates that mechanisms involved in hAR-mediated transactivation are distinct from antihormone-induced receptor inactivation. Furthermore, we show that treatment of transfected cells with a cAMP analog or coexpression of the catalytic subunit of PKA, known to activate hAR, inhibits the binding of SMRT to the AR. This suggests that the association of SMRT with hAR is regulated at the level of cross-talk mechanisms and that ligand-independent receptor activation is due to corepressor dissociation. Taken together, we provide novel insights in AR regulation, antihormone action, and functional nuclear receptor-corepressor interaction.

Macrophage Fcgamma receptors (FcgammaRs) play an important role in the host defense against infection and in the pathophysiology of immune cytopenias. Modulation of macrophage FcgammaR expression is a potential therapeutic approach to immune disorders. Glucocorticoids and progesterones decrease macrophage FcgammaR expression. We assessed the effect of treatment with androgens and antiandrogens on the expression of macrophage FcgammaRs using an experimental guinea pig model. Four androgens (testosterone, dihydrotestosterone, mesterolone, and danazol) and five antiandrogens (flutamide, nilutamide, cyproterone acetate, spironolactone, and finasteride) were studied. Following in vivo treatment of buy eulexin online guinea pigs, we determined the clearance of immunoglobulin G (IgG)-sensitized erythrocytes in vivo, the binding of IgG-sensitized erythrocytes by isolated splenic macrophages, and splenic macrophage FcgammaR cell surface expression. All of the androgens impaired the clearance of IgG-sensitized erythrocytes by decreasing splenic macrophage FcgammaR expression. Dihydrotestosterone and mesterolone were more effective than testosterone or dihydrotestosterone. Flow cytometry and fluorescence microscopy with monoclonal antibodies demonstrated that the androgens decreased the cell surface expression of FcgammaR1,2 more than that of FcgammaR2. Antiandrogens did not significantly alter macrophage FcgammaR expression. Nevertheless, antiandrogens counteracted the effects of androgens on macrophage FcgammaR expression. These data indicate that androgens impair the clearance of IgG-coated cells by decreasing splenic macrophage FcgammaR expression. Thus, androgens other than danazol are candidate drugs for the treatment of immune disorders.

DDE is an environmental pollutant with antiandrogenic properties. Following administration to pregnant rats, DDE was shown to cause feminization in the male offspring at the neonatal stages but did not affect the pubertal growth of accessory sex organs. In this study, we examined the potential of in utero exposure to antiandrogens to alter the responsiveness of the male rats to subsequent DDE challenge. Pregnant Long-Evans rats were dosed by gavage from Gestation Day 14 to 18 at 0, 10 (low dose), or 100 (high dose) mg DDE, or 40 mg flutamide/kg body wt (bw)/day (in utero treatment). At buy eulexin online approximately 80 days of age, the male offspring from each of the four in utero treatment groups were divided into two groups. One group received the adult treatment of four daily gavage administrations of DDE at 70 mg/kg bw (adult treatment), while the second group served as the adult treatment control (adult control). The in utero treatment resulted in 18, 31, and 53% reductions of ventral prostate weights at approximately 85 days of age compared to the control for the low- and high-dose DDE and flutamide groups, respectively. These results suggest that the in utero antiandrogen treatments produced a latent effect on prostate growth that became pronounced only in the postpubertal stage. The in utero treatment also altered the responsiveness of the prostate to the adult treatment, indicated by a significant reduction in ventral prostate weight that was seen only in the control group of the in utero treatment but not in the other groups. The in utero treatment was also associated with expression of testosterone-repressed prostatic message-2 in the adult ventral prostate. In addition, a few prostates in the high-dose DDE- and flutamide-treated groups of the in utero treatment were found to have chronic suppurative prostatitis. While other types of hormonal manipulations have been shown to incite similar responses in rat prostate, the possible linkage between in utero antiandrogen treatment and prostatic inflammation needs to be further evaluated.

To provide insight into androgen-mediated virilization, we measured the androgen receptor in tissues of male and female rat fetuses prior to and during the period of phenotypic sex differentiation. Western immunoblotting was performed utilizing an antibody directed against the 21 amino-terminal segment of the androgen receptor. In immunoblots prepared from urogenital tract tissues of day 17 male and female fetal rats, this antibody specifically recognizes a 110K protein band characteristic of the androgen receptor. Androgen receptor levels were low to undetectable in a variety of non-urogenital tract tissues. After day 18 of fetal development, the amount of androgen receptor decreased in female urogenital tissues, and by day 22 the amount of immunoreactive androgen receptor was higher in the male urogenital sinus and tubercle than in the corresponding tissues of the female. Administration of 5 alpha-dihydrotestosterone to pregnant rats at a dose of 50 mg/kg body weight per day from day 12 to day 22 caused an increase in immunoreactive androgen receptor in the female urogenital sinus and tubercle to levels approaching those in male tissues. Administration buy eulexin online of the androgen antagonist flutamide (100 mg/kg body weight per day) during the same interval caused a reduction in androgen receptor level in the urogenital sinus and tubercle of the male. These findings suggest that androgens modulate the amount of androgen receptor in the embryonic urogenital tract either by inducing the proliferation of androgen-responsive cells or by increasing androgen receptor levels in individual cells.

Japanese encephalitis virus (JEV), which causes neurological disorders, completes its life cycle and triggers apoptotic cell death in infected cells. Dehydroepiandrosterone (DHEA), an adrenal-derived steroid, has been implicated in protection against neurotoxicity and protection of animals from viral-induced encephalitis, resulting in an increased survival rate of the animals. Currently, the mechanisms underlying the beneficial effects of DHEA against the virus are largely unknown. In this study, DHEA suppression of JEV replication and virus-induced apoptosis in murine neuroblastoma (N18) cells was investigated. It was found that DHEA suppressed JEV-induced cytopathic effects, JEV-induced apoptotic cell death and JEV propagation in a concentration-dependent manner. Antiviral activity was more efficient in cultures treated with DHEA immediately after viral adsorption compared with that in Diflucan Liquid Suspension cultures receiving delayed administration after adsorption or transient exposure before adsorption. JEV-induced cytotoxicity was accompanied by the inactivation of extracellular signal-regulated protein kinase (ERK). Inactivation of ERK by JEV infection was reversed by DHEA. When cells were treated with the ERK inhibitor U0126, DHEA lost its antiviral effect. Activation of ERK by anisomycin mimicked the action of DHEA in suppressing JEV-induced cytotoxicity. DHEA-related compounds, such as its sulfate ester (DHEAS) and pregnenolone, were unable to suppress JEV-induced cytotoxicity and ERK inactivation. The hormone-receptor antagonists ICI 182780 and flutamide failed to abrogate the antiviral effect of DHEA. These findings suggest that the antiviral effect of DHEA is not linked directly to the genomic steroid-receptor pathways and suggest that the signalling pathways of ERK play a role in the antiviral action of DHEA.

The in vitro metabolic activation of flutamide, a nitroaromatic antiandrogen which produces hepatitis in a few recipients, was first studied with male rat liver microsomes. There was no electron spin resonance evidence for the reduction of flutamide by reduced nicotinamide adenine dinucleotide phosphate (NADPH)-cytochrome P-450 reductase into a nitro anion free radical. In contrast, flutamide was oxidatively transformed by cytochrome P-450 into reactive metabolite(s) that covalently bound to microsomal proteins. Covalent binding required oxygen and NADPH, and was decreased by the nucleophile glutathione and by the cytochrome P-450 inhibitors SKF 525-A, piperonyl butoxide and troleandomycin (an inhibitor of the cytochrome P-450 3A subfamily). Covalent binding was increased markedly by pretreatment with dexamethasone (an inducer of the cytochrome P-450 3A subfamily) and moderately by pretreatment with beta-naphthoflavone (an inducer of the 1A family). Covalent Topamax Off Brand binding was immunoinhibited markedly by anticytochrome P-450 3A immunoglobulin G and moderately by anticytochrome P-450 1A immunoglobulin G. Covalent binding was much lower with liver microsomes from female rats (not expressing P-450 3A2). Covalent binding of flutamide also occurred with human liver microsomes (where it was inhibited by troleandomycin), and with yeast microsomes expressing human liver cytochromes P-450 1A1, 1A2 or 3A4. We concluded that flutamide was oxidatively transformed into chemically reactive metabolite(s) by rat and human cytochromes P-450, including forms belonging to the 3A and 1A subfamilies.

Although androgens are reported to affect stroke outcomes by altering ischemic tissue damage, their effect on post-injury repair is unknown. Since neurogenesis has recently been recognized as contributing to stroke outcomes, we investigated the role of androgens on stroke-induced neurogenesis. Adult male mice were subjected to transient middle cerebral artery occlusion (MCAO) and neurogenesis was examined 1 week later by quantifying BrdU/doublecortin-positive and BrdU/NeuN-positive neurons in brain germinal regions as well as the injured striatum. To elucidate the role of endogenous androgens, post-MCAO neurogenesis was examined in gonadally intact males, intact males implanted with the androgen receptor antagonist flutamide, and surgically castrated males. Surgical castration or pharmacologic androgen receptor blockade had no effects on post-ischemic neurogenesis, except that continuous androgen receptor blockade unexpectedly suppressed maturation of newborn neurons (BrdU/NeuN-positive cells) in the dentate gyrus. Post-MCAO neurogenesis was also examined in surgically castrated mice treated with continuous release implants containing testosterone or dihydrotestosterone (DHT). Testosterone and DHT robustly inhibited post-ischemic neurogenesis in the dentate gyrus, and the more potent androgen DHT virtually abolished the presence of immature newborn neurons (BrdU/doublecortin-positive cells) in the injured striatum. Our data suggest that endogenous androgens do not alter post-stroke neurogenesis quantitatively, but the presence of supra-physiological androgen stimulation profoundly suppresses early neurogenesis in germinal brain areas and reduces cellular repair in injured tissue after cerebral ischemia. These results advance the understanding of the role that androgens play in Cleocin T Reviews stroke outcomes.

A quantitative analysis of germ-cell populations in normal, hypophysectomized (Hx), and Hx-hormone-treated animals was undertaken during periods of regression that were characterized as intermediate, between short-term and long-term regression of the testis. Twenty-one groups of adult rats were administered either follicle-stimulating hormone (FSH), growth hormone, thyroid-stimulating hormone (TSH), or testosterone (T) in various doses and combinations. The dosage of T administered was less than that expected to achieve maximum testis weight. Flutamide and Casodex were used to compete with androgen binding to receptors in Hx animals, as it is known that small amounts of androgen are secreted in the absence of pituitary stimulation. Follicle-stimulating hormone, T, and TSH all significantly maintained testis weight as compared with Hx controls, although FSH and T, singly or in combination, were the most effective. Contamination of the TSH preparation with trace amounts of FSH was apparently responsible for the slight maintenance of testis weight. A novel assay for determination of the numbers of viable germ cells was used in a subset of these groups to determine the cellular sites of FSH and T action. Numbers of type A spermatogonia were lowered after Hx and were maintained by either FSH or T or a combination of these hormones. Other phases of germ-cell development most susceptible to FSH and/or T were the successive conversions of type A spermatogonia to intermediate spermatogonia, intermediate spermatogonia to type B spermatogonia, preleptotene spermatocytes to pachytene spermatocytes, and early pachytene spermatocytes to intermediate maturity pachytene spermatocytes during early and midcycle phases of pachytene spermatocyte development. Germ-cell loss during meiosis and virtually every phase Priligy Online of spermatid development was largely prevented by FSH or T or a combination of these hormones. Thus, in testes in advanced stages of regression, both FSH and T were capable of preventing cell loss, suggesting that both hormones can affect the survival of the same cell type. The present study demonstrated that FSH can partially compensate for lowered T levels. The combined administration of FSH and T was more effective in preventing overall cell degeneration than either hormone alone. Unlike the initial phase of spermatogenesis, in which there is a largely midcycle loss of germ cells due to Hx, the loss of cells during testis regression is more widespread and impacts several cell types in more than one stage of the spermatogenic cycle.

The 26S proteasome is a ubiquitin-dependent proteolytic system that has been implicated in the regulation of cell Duphaston 60 Mg cycle progression and apoptosis. We investigated the effects of the proteasome inhibitors MG115 and PSI alone or in combination with different concentrations of the antiandrogen hydroxyflutamide on the cellular proliferation, apoptosis and viability of 10 prostatic adenocarcinoma cell cultures. Treatment with both proteasome inhibitors resulted in apoptosis induction, whereas the combinations with hydroxyflutamide generally did not, with the exception of MG115 combined with 10(-7) M hydroxyflutamide. MG115 caused a significant decrease in cellular proliferation, as did the combinations of both proteasome inhibitors with hydroxyflutamide, whereas hydroxyflutamide alone was only effective at a concentration of 10(-5) M. Cellular viability was significantly reduced when both proteasome inhibitors were combined with 10(-5) M hydroxyflutamide. Although the results varied among different cell lines, we conclude that proteasome inhibitors are able to induce apoptosis and reduce cellular proliferation. They might prove effective as antineoplastic substances in prostatic adenocarcinoma alone or in combination with antiandrogens.

We propose a method to quantify positional uncertainties in crystal structures determined by chemical-shift-based NMR crystallography. The method combines molecular dynamics simulations and density functional theory calculations with experimental and computational chemical shift uncertainties. In this manner we find the average positional accuracy as well as the isotropic Flagyl Alcohol and anisotropic positional accuracy associated with each atom in a crystal structure determined by NMR crystallography. The approach is demonstrated on the crystal structures of cocaine, flutamide, flufenamic acid, the K salt of penicillin G, and form 4 of the drug 4-[4-(2-adamantylcarbamoyl)-5-tert-butylpyrazol-1-yl]benzoic acid (AZD8329). We find that, for the crystal structure of cocaine, the uncertainty corresponds to a positional RMSD of 0.17 Å. This is a factor of 2.5 less than for single-crystal X-ray-diffraction-based structure determination.

A simple and rapid method of measuring 5 alpha-reductase (5 alpha-R) activity and of determining the kinetic parameters (KM and Vmax) of the enzyme is described. The 5 alpha-R activity in the homogenate of the prostate of Wistar rats aged 8-12 weeks was established, and the effects of natural and synthetic steroids and of non-steroidal antiandrogens (IC50) upon the 5 alpha-R activity were studied. Of the natural steroids, 17-OH-progesterone was found to Diovan 20 Mg have the highest inhibitory effect (IC50 = 1.35 microM), followed in decreasing order by progesterone (IC50 = 5.0 microM) and 4-androstene-3,17-dione (IC50 = 21.6 microM). Oestradiol-17 beta had practically no inhibitory effect. Of the synthetic steroids, 4-MA had the highest inhibitory effect (IC50 = 0.068 microM), followed by nortestosterone (IC50 = 7.4 microM) and RU-486 (Mifepristone) (IC50 = 115 microM). Even at 1000 microM, cyproterone acetate exerted no inhibitory effect. Of the nonsteroidal compounds, ketoconazole proved a weak inhibitor (IC50 = 115 microM), while flutamide was practically ineffective.

The growth of hepatocellular carcinoma (HCC) is thought to be dependent on androgens, as androgen receptors are present in most of these tumors. The aim of this multicenter trial was to assess the effect of antiandrogens in patients who have advanced HCC. Male patients with advanced HCC were randomized into 2 groups treated with (1) leuprorelin (3.75 mg/mo subcutaneously), flutamide (750 mg/d orally), and tamoxifen (30 mg/d orally) or (2) tamoxifen alone (30 mg/d orally) administered until death. Survival was the main end point (log-rank test). The required sample size was 375 patients (alpha, 5%; beta, 10%; 1-year survival, 45% in treated group and 30% in controls). Between February 1994 and January 1998, 376 male patients (mean age, 66 years; treated group, n = 192; control group, n = 184) were included. No baseline imbalance was found between the groups. At the reference date (January 1, 2003), 183 deaths (95.3%) were observed in the treated group and 177 deaths (96.2%) were observed in controls. Thirteen patients were lost to follow-up. Median survival time was estimated to be 135.5 days (95% CI, 112-189) and 176 days (95% CI, 141-227) in treated and control groups, respectively (P = .21). Crude and adjusted relative risks of death in the treated group were estimated at 1.14 (95% CI, 0.93-1.40) and 1.08 (95% CI, 0.87-1.33; P = .48) respectively. Premature interruption of treatment was more frequent in the treated group (n = 45) than in controls (n = 22; P = .0045), mainly because of digestive side effects. In conclusion, no benefit in survival was found with antiandrogenic treatment in male patients with advanced HCC.
