Although prostate cancer is traditionally considered a disease of old age, improved diagnostic techniques have resulted in early diagnosis, and many men are now treated while still physically and sexually active. Current therapies for prostate cancer often include medical or surgical castration, which cause adverse effects on physical and sexual function; therefore, greater attention has been focused on quality of life. The nonsteroidal antiandrogen bicalutamide is an effective agent with a favorable tolerability profile and, in some settings, represents an alternative to castration. Mature survival data reveal that bicalutamide monotherapy provides survival benefits for untreated locally advanced disease that do not differ significantly from those of castration and maintains better physical capacity and sexual interest. Recent data from a prospective randomized trial demonstrate that bicalutamide given as immediate therapy, either alone or as adjuvant to therapy of curative intent, significantly reduces the risk of objective disease progression in patients with localized or locally advanced prostate cancer. Antiandrogens are also used in combination with castration, a treatment known as combined androgen blockade (CAB), for advanced disease. A randomized trial demonstrated that CAB with bicalutamide is associated with similar survival outcome to CAB with flutamide and is better tolerated. Current evidence demonstrates that bicalutamide currently has a favorable risk-benefit ratio in several stages of prostate cancer and that the role of bicalutamide will be further defined by ongoing studies.

In this investigation the effect of CPA was tested in comparison to FL after the procedure of double blinding on the ventral prostate of 70 adult male castrated Copenhagen-Fisher rats and on the Dunning R-3327 H tumor. Total androgen blockade by castration plus CPA or by castration plus FL induced significant decrease in prostate weight compared to the androgen deprivation by castration alone. No significant difference between CPA and FL was observed. Furthermore it was impossible to exaggerate this effect with higher doses of CPA of FL. The Dunning R-3327 H tumor did not become palpable 60 days after inoculation of the tumor cells indicating that androgen deprivation by total androgen blockade by castration plus CPA or plus FL did not exhibit any proliferative activity on the hormone-sensitive Dunning R-3327 H tumor cells.

1. The effect of androgens 5 beta- and 5 alpha-dihydrotestosterone (DHT, 10(-9) M), and the antiandrogens cyproterone acetate (CPA, 10(-8)-10(-6) M), chlormadinone acetate (CMA, 10(-8)-10(-6) M), medroxyprogesterone acetate (MPA, 10(-8)-10(-6) M), spironolactone (SPI, 10(-5) M), flutamide (F, 10(-5) M) and cimetidine (C, 10(-5) M), on inotropic positive effect induced by ouabain (10(-8)-10(-5) M) and isoproterenol (10(-8)-10(-6) M), on electrically stimulated left atria of rat, has been assayed. 2. Ouabain (10(-6) M) did not modify the inotropic effect of isoproterenol (10(-8)-10(-6) M). 3. The androgens 5 beta- and 5 alpha-DHT (10(-9) M) and the antiandrogens SPI (10(-6) M), F (10(-5) M) and C (10(-5) M) inhibit the inotropic effect of ouabain and isoproterenol on electrically stimulated left atria of the rat. 4. The antiandrogens CPA, MPA and CMA to 10(-7) M, inhibit the inotropic effect of ouabain. The CPA (10(-8)-10(-6) M) inhibit, in a dose-dependent way the positive inotropic effect of isoproterenol. MPA and CMA (10(-8)-10(-6) M) also inhibit the inotropic effect isoproterenol but the inhibitory effect is greater with 10(-8) M than 10(-6) M of both drugs. 5. Taken together, our results suggest that steroidal hormones could modulate the cardiac contractility through interference with Na-pump in a non-digitalic site and/or with intracellular mediators in left atrium.

144 men with a mean age of 64.8±10.3 years participated, with a median follow up of 8.2 years. HER-2 was expressed in 20.8% of primary tumors; it was associated with vascular infiltration and older age, but not with other clinical pathological findings. Some 40.3% of men had secondary CPCs detected, of which 38% expressed HER-2. Men CPC (+) had a higher frequency of biochemical failure, but there was no difference in HER-2 expression of CPCs with the frequency of biochemical failure. After androgen blockade, men with HER-2 (+) positive secondary CPCs had a higher frequency of disease progression to castrate resistant disease.

As has been clearly demonstrated in prostate and breast cancer, progression to hormone insensitivity is a major problem responsible for the usually partial and short-lived response to antihormonal therapy. Preincubation of androgen-sensitive Shionogi mouse carcinoma cells for 15 days in the absence of androgens causes the development of complete resistance of cell growth to androgens. Of potentially important therapeutic significance is the finding that androgen sensitivity can be maintained not only by the androgen dihydrotestosterone (DHT) but also by incubation with the pure antiandrogen Flutamide-OH in the absence of androgens. Since androgen resistance is one of the main problems facing the treatment of prostate cancer, the possibility of avoiding or at least delaying the development of androgen resistance with a pure antiandrogen could well provide the basis for improving the success of therapy for this disease.

Androgens produce proliferative effect on the prostate and negatively regulate the AR transcription.

The changes in BMD positively correlated with changes in total testosterone level. The BMD decreases during the androgen suppression and increases during the pause in the treatment. This demonstrates the benefit of intermittent AST in preventing osteoporosis, pathological bone fractures and possibly, bone metastases.

Published reports where agent(s) known to act via steroid hormone receptors were discontinued in patients with relapsing prostatic cancer were retrieved from MEDLINE listings. The trials included patients who progressed on steroidal and nonsteroidal antiandrogens, progestational agents, and estrogens. Included were the specifics of all treatments administered prior to discontinuation of the drugs, concomitant therapies, and factors that might predict a favorable response to "withdrawal."

Attention-deficit/hyperactivity disorder (AD/HD) is a common pediatric behavioral disorder associated, in part, with male preponderance and reduced regional cerebral blood flow (rCBF). However, mechanism(s) underlying male preponderance and reduced rCBF in AD/HD are unclear. The present study profiles the expression of angiogenic and hormonal factors likely to underlie these symptoms using a recently characterized AD/HD animal model, juvenile male stroke-prone spontaneously hypertensive rats (SHRSP). Because vascular endothelial growth factor (VEGF) signaling cascade and gonadal steroids are key regulators of angiogenesis and gender-based behavior, respectively, we profiled their patterns of expression in the frontal cortex of SHRSP to elucidate their roles in the genesis of AD/HD male preponderance and rCBF. Interestingly, levels of VEGF, VEGF receptors (KDR, Flt-1), endothelial nitric oxide synthase, phosphorylated Akt (pAkt), estrogen receptor-alpha, aromatase, and capillary density in sham-operated SHRSP were remarkably down-regulated, whereas androgen receptor levels were up-regulated, compared with age-matched genetic control, Wistar-Kyoto rats. Castration, estrogen, and androgen receptor antagonist (flutamide) counteracted these effects. Dihydrotestosterone, but not testosterone, reversed the beneficiary effects of castration. Estrogen receptor-beta levels remained unchanged in all groups examined. We postulate that changes in androgen metabolism that tend to up-regulate local dihydrotestosterone concentration and diminish estrogen synthesis, in the frontal cortex of juvenile male SHRSP, may lower levels and/or activity of VEGF and its signaling cascade and, subsequently, reduce rCBF. These findings could, in part, help explain the pathogenesis of reduced rCBF and male preponderance in AD/HD.

Flutamide, a competitive androgen receptor blocker, reduces gubernacular mitosis to basal levels until day 6, highlighting the importance of androgen receptor. Excess DNA accumulation in TS rats is consistent with the known excess of GFN fibers and calcitonin gene-related peptide in this mutant. Capsaicin-inhibited mitosis in both Celebrex Dosage day 2 SD and TS rats suggests that the GFN mediates androgen action on early postnatal gubernacular DNA synthesis and growth.

AT2R mRNA and protein expression levels were lower in the aortas of males than females. In males, testosterone withdrawal by castration significantly elevated AT2R mRNA and protein levels and testosterone replacement restored them. In females, increasing androgen levels decreased AT2R mRNA and protein expression and this was attenuated by androgen receptor blocker flutamide. Ex vivo, dihydrotestosterone downregulated AT2R in endothelium-intact but not endothelium-denuded aorta. Dihydrotestosterone-induced AT2R downregulation in isolated aorta was blocked by an androgen receptor antagonist. Furthermore, blockade of ERK1/2 but not p38 MAP kinase or TGFβ signaling Omnicef Max Dose with specific inhibitors abolished dihydrotestosterone-induced AT2R downregulation.

The modified Ferriman-Gallwey scores for hirsutism decreased significantly at months 6 and 12 from a mean +/- SEM of 17.8 +/- 0.9 to 6.0 +/- 0.6 (P < 0.001) and 17.8 +/- 0.9 to 4.8 +/- 0.7 (P < 0.001) in group I and from 17.0 +/- 0.9 to 6.6 +/- 0.7 and 17. Feldene 40 Mg Par Jour 0 +/- 0.9 to 5.2 +/- 0.7 (P < 0.001) in group II, respectively. The reductions in hirsutism scores (mean +/- SEM) were similar in group I at 6 months (64.6% +/- 2.5%) and at 12 months (71.2% +/- 2.2%) and in group II at 6 months (62.1% +/- 3.0%) and at 12 months (70.3% +/- 3.0%). The percent reductions in hirsutiam scores at 6 and at 12 months were similar within group I (64.6% +/- 2.5% and 71.2% +/- 2.2%) and group II (62.1% +/- 3.0% and 70.3% +/- 3.0%), respectively. The decreases in hirsutism scores in the first 6 months were more significant than in the last 6 months of treatment in both groups. There were no significant differences in any of the hormone levels during therapy in either group. One patient in group II was excluded from the study because of liver dysfunction.

The mammalian external genitalia are specialized appendages for efficient copulation, internal fertilization and display marked morphological variation among species. In this paper, we described the embryonic development of mouse genital tubercle (GT), an anlage of the external genitalia utilizing the scanning electron microscope (SEM) analysis. It has been shown that the Distal Urethral Epithelium (DUE) may fulfill an essential role in the outgrowth control of the GT. Our present SEM analysis revealed a small distal protrusion at the tip Flagyl 1000 Mg of the GT of normal embryos as well as some morphological differences between male and female embryonic external genitalia. Previous analysis shows that the teratogenic dose of Retinoic Acid (RA) induces a drastic marformation of the urethral plate, but not gross abnormalities for GT outgrowth. Interestingly, a small distal protrusion at the tip of GT was clearly observed also after RA treatement. Furthermore, we showed that treatment with anti-androgen flutamide resulted in the demasculinization of the GT in males. The unique character of GT development and the sexual dimorphism are discussed.

The purpose of this study was twofold. First, we sought to identify candidate markers of exposure to anti-androgens by analyzing endogenous metabolite profiles in the urine of male fathead minnows (mFHM, Pimephales promelas). Based on earlier work, we hypothesized that unidentified lipids in the urine of mFHM were selectively responsive to exposure to androgen receptor antagonists, which is otherwise difficult to confirm using established fish toxicity assays. A second goal was to evaluate the feasibility of non-lethally and repeatedly sampling urine from individual mFHMs over the time course of response to a chemical exposure. Accordingly, we exposed mFHM to the model anti-androgens vinclozolin or flutamide. Urine was collected from each fish at 48hour intervals over the course of a 14day exposure. Parallel experiments were conducted with mFHM exposed to bisphenol A or control water. The frequent handling/sampling regime did not cause apparent adverse effects on the fish. Endogenous metabolite profiling was conducted with gas chromatography-mass spectrometry (GC-MS), which exhibited lower variation for the urinary metabolome than was found in earlier work with nuclear magnetic resonance (NMR) spectroscopy. Specifically, for inter- and intra-individual variations, the median spectrum-wide relative standard deviation (RSD) was 32.6% and 33.3%, respectively, for GC-MS analysis of urine from unexposed mFHM. These results compared favorably with similar measurements of urine from other model species, including the Sprague Dawley rat. In addition, GC-MS allowed us to Abilify Maintena Cost identify several lipids (e.g., certain saturated fatty acids) in mFHM urine as candidate markers of exposure to androgen receptor antagonists.

The molecular mechanisms responsible for the sexual differentiation of the zebra finch song system remain mysterious. Androgen receptors are expressed in a sexually dimorphic fashion in the zebra finch song system: males have more cells expressing androgen receptors, and this sex difference appears very early in development (day 9 posthatch). Estrogen administration to hatchling females up-regulates androgen receptor expression in their song system and profoundly masculinizes their song system's morphology. Co-administering flutamide, an androgen receptor blocker, with estrogen impedes estrogen's masculinizing effects on the song system, suggesting that androgens are required for masculine development. Accordingly, to investigate further the role of androgens in the sexual differentiation of the zebra finch song system, we sought to block androgen activity in males by administering large, sustained doses of flutamide from just before androgen receptors are expressed in the song system (day 7) through to the day of sacrifice (days 61-63). Flutamide profoundly reduced the size of the testes, demonstrating that Neurontin 150 Mg this drug and mode of administration could have a large impact on tissues. In contrast, flutamide had only a minor impact on the song system: the number of RA neurons was slightly reduced, and the corrected HVC volume showed a trend toward demasculinization. Other brain measures (uncorrected HVC, and corrected and uncorrected volumes of Area X, lMAN, RA, and Rotundus; neuron size in lMAN, HVC, and RA; and number of HVC and LMAN neurons) were not significantly affected. The present results do not support an important role for androgen in masculinizing the song circuit after posthatch day 7.

Di(n-butyl) phthalate (DBP) has antiandrogenic-like effects on the developing reproductive tract in the male rat and produces regions of interstitial cell hyperplasia and gonocyte degeneration in the developing fetal testes at maternal doses of 100-500 mg/kg/day. Neither DBP nor its primary metabolites interact with the androgen receptor in vitro. The present study was performed to examine gene expression in the fetal rat testes following in utero DBP exposure. Pregnant Sprague-Dawley rats received corn oil, DBP (500 mg/kg/day), or flutamide (reference antiandrogen, 50 mg/kg/day) by gavage daily from gestation day (GD) 12 to 21. Dose levels were selected to maximize fetal response with minimal maternal toxicity. Testes were isolated on GD 16, 19, and 21. Global changes in gene expression were determined by microarray analysis. Selected genes were further examined by quantitative RT-PCR. DBP, but not flutamide, reduced expression of the steroidogenic enzymes cytochrome P450 side chain cleavage, cytochrome P450c17, and steroidogenic acute regulatory protein. Testicular testosterone and androstenedione were decreased on GD 19 and 21, while progesterone was increased on GD 19 in DBP-exposed testes. Testosterone-repressed prostate message-2 (TRPM-2) was upregulated, while c-kit (stem cell factor receptor Glucotrol Diabetic Pills ) mRNA was downregulated following DBP exposure. TRPM-2 and bcl-2 protein staining was elevated in GD 21 DBP-exposed Leydig and Sertoli cells. Results of this study have led to the identification of several possible mechanisms by which DBP can induce its antiandrogenic effects on the developing male reproductive tract without direct interaction with the androgen receptor. Our results suggest that the antiandrogenic effects of DBP are due to decreased testosterone synthesis. In addition, enhanced expression of cell survival proteins such as TRPM-2 and bcl-2 may be involved in DBP-induced Leydig cell hyperplasia, whereas, downregulation of c-kit may play a role in gonocyte degeneration. Future studies will explore the link between these identified gene expression alterations and ultimate adverse responses.

Flutamide is due to its properties as a practically water-insoluble, high-dose drug substance a typical representative of a drug with particle size limited dissolution rate and bioavailability. An in vitro dissolution test method comprising of standard paddle stirrer, round-bottomed vessel of 4 l capacity, and 0.1 N hydrochloric acid with 0.5% of sodium lauryl sulphate as dissolution medium, was developed. The dissolution method was shown discriminatory and predictive regarding bioavailability of conventional 250 mg flutamide tablets with different in vitro dissolution rates. Relative bioavailability of flutamide from the tablets, determined as AUC of the active metabolite 2-hydroxyflutamide in healthy male subjects, could be correlated with drug amount dissolved during 45 min in the in vitro test. Also bioavailability data from four different biostudies could be compared utilising the calculated ratios R(AUC) and R(Diss.) for the test and reference formulations in the individual studies. It is suggested that the concept of R(AUC) and R(Diss.) can also be applied to other orally administered, poorly soluble, high-dose drug substances with dissolution rate limited bioavailability.
