It is a common condition, affecting 2-5% of children aged 3 months to five years. An autosomal dominant pattern of inheritance has been identified in some families. The majority are simple febrile seizures (generally defined as generalized onset, single seizures with a duration of less than 30 minutes). Complex febrile seizures are characterized by focal onset, duration greater than 30 minutes, and/or more than one seizure in a 24 hour period. The likelihood of developing epilepsy (i.e., a nonfebrile seizure disorder) following simple febrile seizures is low.

Switch from antagonist to agonist of the androgen receptor bicalutamide is associated with prostate tumour progression in a new model system. (1/288)

Advanced prostate cancer is treated by androgen ablation and/or androgen receptor (AR) antagonists. In order to investigate the mechanisms relevant to the development of therapy-resistant tumours, we established a new tumour model which closely resembles the situation in patients who receive androgen ablation therapy. Androgen-sensitive LNCaP cells were kept in androgen-depleted medium for 87 passages. The new LNCaP cell subline established in this manner, LNCaP-abl, displayed a hypersensitive biphasic proliferative response to androgen until passage 75. Maximal proliferation of LNCaP-abl cells was achieved at 0.001 nM of the synthetic androgen methyltrienolone (R1881), whereas 0.01 nM of this compound induced the same effect in parental cells. At later passages (> 75), androgen exerted an inhibitory effect on growth of LNCaP-abl cells. The non-steroidal anti-androgen bicalutamide stimulated proliferation of LNCaP-abl cells. AR protein expression in LNCaP-abl cells increased approximately fourfold. The basal AR transcriptional activity was 30-fold higher in LNCaP-abl than in LNCaP cells. R1881 stimulated reporter gene activity in LNCaP-abl cells even at 0.01 nM, whereas 0.1 nM of R1881 was needed for induction of the same level of reporter gene activity in LNCaP cells. Bicalutamide that acts as a pure antagonist in parental LNCaP cells showed agonistic effects on AR transactivation activity in LNCaP-abl cells and was not able to block the effects of androgen in these cells. The non-steroidal AR blocker hydroxyflutamide exerted stimulatory effects on AR activity in both LNCaP and LNCaP-abl cells; however, the induction of reporter gene activity by hydroxyflutamide was 2.4- to 4-fold higher in the LNCaP-abl subline. The changes in AR activity were associated neither with a new alteration in AR cDNA sequence nor with amplification of the AR gene. Growth of LNCaP-abl xenografts in nude mice was stimulated by bicalutamide and repressed by testosterone. In conclusion, our results show for the first time that the nonsteroidal anti-androgen bicalutamide acquires agonistic properties during long-term androgen ablation. These findings may have repercussions on the natural course of prostate cancer with androgen deprivation and on strategies of therapeutic intervention.  (+info)

Inhibition of p160-mediated coactivation with increasing androgen receptor polyglutamine length. (2/288)

Normal polymorphic size variation of the exon 1 CAG microsatellite of the androgen receptor (AR) is associated with prostate cancer, benign prostatic hyperplasia and male infertility. Furthermore, abnormal expansion of the satellite leads to Kennedy's disease. We have shown recently that the AR N-terminal domain (NTD), which contains the polyglutamine (polyQ) stretch (encoded by the CAG repeat), functionally interacts with the C-termini of p160 coactivators. In the present study we explored possible AR CAG size effects on the p160 coactivator-mediated transactivation activity of the receptor. First, we mapped the p160 coactivator interaction on the AR NTD and found an interaction surface between amino acids 351 and 537. Although this region is 'downstream' from the polyQ stretch, it is still within the AR NTD, is implicated in constitutive transactivation activity of the receptor, and thus might be subject to polyQ size modulation. Indeed, cotrans- fection experiments in cultured prostate epithelial cells, using AR constructs of varying CAG sizes and p160 coactivator expression vectors, revealed that increased polyQ length, up to a size of 42 repeats, inhibited both basal and coactivator-mediated AR transactivation activity. AR expression in these cells, on the other hand, was unaffected by the same increased CAG repeat size range. We conclude that the AR NTD contributes to AR transactivation activity via functional interactions with p160 coactivators and that increasing polyQ length negatively affects p160-mediated coactivation of the AR. This molecular mechanism thus might explain, at least in part, the observed phenotypic effects of the AR CAG size polymorphism.  (+info)

Acute impairment of relaxation by low levels of testosterone in porcine coronary arteries. (3/288)

OBJECTIVES: While there are many suggested reasons for the marked gender bias in cardiovascular events, much of the available data indicate that circulating estrogens are cardioprotective. The possibility that endogenous androgens may be detrimental to the cardiovascular system has received relatively less attention. We investigated the short-term modulatory effects of various concentrations of testosterone on vascular function in isolated porcine coronary artery rings. RESULTS: The higher concentrations (> 1 microM) of testosterone relaxed U46619-contracted coronary artery rings in an endothelium-independent manner. This direct effect was insensitive to the testosterone receptor antagonists, flutamide and cyproterone acetate. Short-term exposure (20 min) to low levels of testosterone (1-100 nM), which were ineffective on their own on vascular function, significantly diminished relaxation to bradykinin and calcium ionophore A23187 but not those produced by levcromakalim and sodium nitroprusside. The inhibitory effect observed with 1 nM testosterone was only partially reversed by flutamide and cyproterone acetate and unaltered in the presence of actinomycin D and cycloheximide. CONCLUSIONS: These results demonstrate that acute treatment with testosterone, at concentrations that have no effect on their own, reduces vasorelaxation. Furthermore, they suggest that this modulatory action may be in part independent of the classical testosterone receptor since it was not completely sensitive to the anti-androgens and was not inhibited by the transcriptional and translational inhibitors. These findings support the postulation that testosterone may have unfavorable influences on vascular function.  (+info)

Differential effects of 17beta-estradiol and testosterone on the contractile responses of porcine coronary arteries. (4/288)

1. We investigated the effects of short-term exposure to physiological levels of 17beta-estradiol and testosterone on vasocontractile responses in porcine coronary artery rings. 2. Concentration-response curves to endothelin-1, 5-hydroxytryptamine, the thromboxane analogue U46619 and KCl were constructed in endothelium-intact and endothelium-disrupted artery rings. 3. Thirty minutes exposure to 17beta-estradiol (1 and 30 nM) significantly attenuated vasoconstriction to endothelin-1, 5-hydroxytryptamine and U46619. Conversely, the same concentrations of testosterone significantly potentiated responses elicited by these contractile agents. These inhibitory effects of 17beta-estradiol and enhancing actions of testosterone on contractions were endothelium-independent. KCl-mediated contractions were unaffected by the presence of either sex hormones. 4. The oestrogen receptor antagonists, tamoxifen (10 microM) and ICI 182,780 (10 microM), were unable to reverse the inhibitory influence 1 nM 17beta-estradiol had on the agonist-mediated contractile responses. Similarly, the androgen receptor antagonists, flutamide (10 microM) and cyproterone acetate (10 microM), failed to affect the potentiating activities of 1 nM testosterone. The alteration in vasoconstrictive responses observed following acute exposure to either 1 nM 17beta-estradiol and 1 nM testosterone were apparent even in the presence of the protein synthesis inhibitor cycloheximide (10 microM) and the transcription inhibitor actinomycin D (10 microM). 6. In conclusion, we report a unique type of sex hormone action on the coronary vasculature. These events occur at low nanomolar concentrations of 17beta-estradiol and testosterone, are insensitive to conventional sex hormone receptor antagonists, are not blocked by de novo protein synthesis inhibitors and have rapid time-courses that are uncharacteristic of classical genomic activities.  (+info)

Specific recognition of androgens by their nuclear receptor. A structure-function study. (5/288)

Androgens, like progestins, are 3-ketosteroids with structural differences restricted to the 17beta substituent in the steroid D-ring. To better understand the specific recognition of ligands by the human androgen receptor (hAR), a homology model of the ligand-binding domain (LBD) was constructed based on the progesterone receptor LBD crystal structure. Several mutants of residues potentially involved in the specific recognition of ligands in the hAR were constructed and tested for their ability to bind agonists. Their transactivation capacity in response to agonist (R1881) and antagonists (cyproterone acetate, hydroxyflutamide, and ICI 176344) was also measured. Substitution of His(874) by alanine, only marginally impairs the ligand-binding and transactivation capacity of the hAR receptor. In contrast, mutations of Thr(877) and, to a greater extent, Asn(705) perturb ligand recognition, alter transactivation efficiency, and broaden receptor specificity. Interestingly, the N705A mutant acquires progesterone receptor (PR) properties for agonist ligands but, unlike wild type AR and PR, loses the capacity to repress transactivation with nonsteroidal antagonists. Models of the hAR.LBD complexes with several ligands are presented, which suggests new directions for drug design.  (+info)

The RING finger protein SNURF modulates nuclear trafficking of the androgen receptor. (6/288)

The androgen receptor (AR) is a transcription factor that mediates androgen action. We have used the green fluorescent protein (GFP) technique to investigate dynamics of nuclear trafficking of human AR in living cells. In the absence of ligand, the GFP-AR fusion protein is distributed between cytoplasm and nuclei. Androgen exposure leads to a rapid and complete import of GFP-AR to nuclei of CV-1 cells (>=90% nuclear in 30 minutes), whereas a pure antiandrogen, Casodex, elicits a slower (<40% nuclear in 30 minutes) and incomplete transfer. Unliganded ARs with mutations in the basic amino acids of the bipartite nuclear localization signal (NLS) within the second zinc finger and the hinge region are predominantly cytoplasmic and their androgen-dependent nuclear import is severely compromised ((3/4)20% nuclear in 30 minutes). Interestingly, substitutions of the Leu residues flanking the bipartite NLS lead to inefficient nuclear transfer in response to androgen ((3/4)20% nuclear in 30 minutes). The ligand-binding domain of AR, which represses bipartite NLS activity, contains an agonist-specific NLS. The small nuclear RING finger protein SNURF, which interacts with AR through a region overlapping with the bipartite NLS, facilitates AR import to nuclei and retards its export on hormone withdrawal. More AR is associated with the nuclear matrix in the presence than absence of coexpressed SNURF. We suggest that the SNURF-mediated tethering of AR in nuclei represents a novel mechanism for activating steroid receptor functions.  (+info)

Antiandrogenic effects of novel androgen synthesis inhibitors on hormone-dependent prostate cancer. (7/288)

We have found that in addition to being potent inhibitors of 17alpha-hydroxylase/C17,20-lyase and/or 5alpha-reductase, some of our novel androgen synthesis inhibitors also interact with the mutated androgen receptor (AR) expressed in LNCaP prostate cancer cells and the wild-type AR expressed in hormone-dependent prostatic carcinomas. The effects of these compounds on the proliferation of hormone-dependent human prostatic cancer cells were determined in vitro and in vivo. L-2 and L-10 are delta4-3-one-pregnane derivatives. L-35 and L-37 are delta5-3beta-ol-androstane derivatives, and L-36 and L-39 are delta4-3-one-androstane-derived compounds. L-2, L-10, and L-36 (L-36 at low concentrations) stimulated the growth of LNCaP cells, indicating that they were interacting agonistically with the mutated AR expressed in LNCaP cells. L-35, L-37, and L-39 acted as LNCaP AR antagonists. To determine whether the growth modulatory effects of our novel compounds were specific for the mutated LNCaP AR, competitive binding studies were performed with LNCaP cells and PC-3 cells stably transfected with the wild-type AR (designated PC-3AR). Regardless of AR receptor type, all of our novel compounds were effective at preventing binding of the synthetic androgen methyl-trienolone[17alpha-methyl-(3H)-R1881 to both the LNCaP AR and the wildtype AR. L-36, L-37, and L-39 (5.0 microM) prevented binding by >90%, whereas L-35 inhibited binding by 30%. To determine whether the compounds were acting as agonists or antagonists, LNCaP cells and PC-3AR cells were transfected with the pMAMneoLUC reporter gene. When luciferase activity was induced by dihydrotestosterone, all of the compounds were found to be potent inhibitors of transcriptional activity, and the pattern of inhibition was similar for both receptor types. However, L-2, L-10, and L-36 were determined to be AR agonists, and L-35, L-37, and L-39 were wild-type AR antagonists. When tested in vivo, L-39 was the only AR antagonist that proved to be effective at inhibiting the growth of LNCaP prostate tumor growth. L-39 slowed tumor growth rate in LNCaP tumors grown in male SCID mice to the same level as orchidectomy, significantly reduced tumor weights (P < 0.05), significantly lowered serum levels of prostate-specific antigen (P < 0.02), and significanty lowered serum levels of testosterone (P < 0.05). L-39 also proved to be effective when tested against the PC-82 prostate cancer xenograft that expresses wild-type AR. These results show that some of our compounds initially developed to be inhibitors of androgen synthesis also interact with the human AR and modulate the proliferation of hormone-dependent prostatic cancer cells. Therefore, compounds such as L-39, which have multifunctional activities, hold promise for the treatment of androgen-dependent prostate tumors.  (+info)

Androgen receptor antagonism by the organophosphate insecticide fenitrothion. (8/288)

Organophosphate insecticides represent one of the most widely used classes of pesticides with high potential for human exposure in both rural and residential environments. We investigated the interaction of the organophosphothioate pesticide fenitrothion (O,O-dimethyl O-(4-nitro-m-tolyl) phosphorothioate) with the human androgen receptor (AR). Fenitrothion blocked dihydrotestosterone-dependent AR activity in a concentration-dependent and competitive manner in HepG2 human hepatoma liver cells transiently transfected with human AR and an AR-dependent luciferase reporter gene. Schild regression analysis yielded an equilibrium dissociation constant value of 2.18 x 10(-8) M. To determine the antiandrogenic potential of fenitrothion in vivo, 7-week-old castrated Sprague-Dawley rats were dosed once a day for 7 days with testosterone propionate (50 microg/day, sc) plus gavage doses of either corn oil vehicle or fenitrothion (15 or 30 mg/kg/day). An additional group of rats was given testosterone propionate and flutamide (50 mg/kg/day). Motor activity and acetylcholinesterase activity in whole blood and brain were also assessed. Both fenitrothion and the reference antiandrogen flutamide caused significant decreases in the ventral prostate, seminal vesicle, and levator ani plus bulbocavernosus muscles tissue weights. In contrast, blood acetylcholinesterase activity, a standard biomarker of organophosphate poisoning, was only inhibited at the higher dose of fenitrothion (30 mg/kg). Our results demonstrate that fenitrothion is a competitive AR antagonist, comparable in potency to the pharmaceutical antiandrogen flutamide and more potent, based on in vitro assays, than the known environmental antiandrogens linuron and p,p'-, 2,2-bis(p-hydroxyphenyl)-1,1-dichloroethylene ( p,p'-DDE).  (+info)

3178 In the treatment of prostate cancer (PC), castration-based therapies, which are well established with GnRH agonist or surgical castration, cause decreased libido, sexual dysfunction, and osteoporosis, which reduce patients quality of life (QOL). Considering the increase in PC patients diagnosed at earlier stages of the disease and at a younger age, monotherapy with nonsteroidal androgen receptor (AR) antagonists is an attractive therapeutic alternative to castration-based therapies, offering effective therapy with potential benefits with respect to QOL. In this study, we evaluated the pharmacological profiles of YM580, a novel nonsteroidal AR antagonist, in comparison with bicalutamide (BIC), which is most extensively studied as monotherapy. YM580 bound specifically to human AR with an affinity 4 times more potent than BIC. YM580 inhibited the dihydrotestosterone-dependent transcriptional activity of human AR 10 times more potently than BIC did. After once-daily oral administration for 5 ...

FDA hasnt actually made any big decisions about SARMs, contrary to what some may think. The research behind the drug is actually very extensive. Its not primarily being looked at from a body-building standpoint, but rather as a substance that could potentially help people with degenerative muscle disorders. One reason this type of help could be beneficial is due to its minimal side effects. Many current medical drugs for muscular diseases have problematic side effects, leaving patients with no room for options. As scientists and Big Pharma companies continue to research and test these type of products, experts expect to see a large increase in popularity in the future due to its highly promising effects.. However, muscle degeneration isnt the only possible benefit to developing products like SARMs. Derivatives like MK-677 are being tested as hormone-balancers, which have been known to help overall immune systems, improve sleep patterns, and increase energy without adding a spike of ...

Three separate studies of treatments for prostate cancer reported at the 2014 ASCO Annual Meeting in Chicago showed excellent, intermediate, and disappointing results. An update of the previously reported PREVAIL trial (see March 1 issue of The ASCO Post, page 1) was overwhelmingly positive for the androgen receptor antagonist enzalutamide (Xtandi). A second study showed that the androgen-synthesis inhibitor orteronel improved radiographic progression-free survival but failed to improve overall survival, while a third study of the monoclonal antibody cixutumumab was negative.. Enzalutamide a Home Run. "In the PREVAIL trial, treatment with enzalutamide significantly delayed radiographic progression-free survival, significantly reduced the risk of death by nearly 30%, delayed the time to initiation of cytotoxic chemotherapy, and improved quality of life on the FACT-P.

Prostate cancer progression requires active androgen receptor (AR) signaling which occurs following translocation of AR from the cytoplasm to the nucleus. Chemotherapy with taxanes improves survival in patients with castrate resistant prostate cancer (CRPC). Taxanes induce microtubule stabilization, mitotic arrest, and apoptotic cell death, but recent data suggest that taxanes can also affect AR signaling. Here, we report that taxanes inhibit ligand-induced AR nuclear translocation and downstream transcriptional activation of AR target genes such as prostate-specific antigen. AR nuclear translocation was not inhibited in cells with acquired β-tubulin mutations that prevent taxane-induced microtubule stabilization, confirming a role for microtubules in AR trafficking. Upon ligand activation, AR associated with the minus-end-microtubule motor dynein, thereby trafficking on microtubules to translocate to the nucleus. Analysis of circulating tumor cells (CTC) isolated from the peripheral blood of ...
Background: The chemopreventive effects of resveratrol (RSV) on prostate cancer have been well established; the androgen receptor (AR) plays pivotal roles in prostatic tumorigenesis. However, the exact underlying molecular mechanisms about the effects of RSV on AR have not been fully elucidated. A model system is needed to determine whether and how RSV represses AR transcriptional activity. Methodology: The AR cDNA was first cloned into the retroviral vector pOZ-N and then integrated into the genome of ARnegative HeLa cells to generate the AR(+) cells. The constitutively expressed AR was characterized by monitoring hormonestimulated nuclear translocation, DNA binding, and transcriptional activation, with the AR(-) cells serving as controls. AR(+) cells were treated with RSV, and both AR protein levels and AR transcriptional activity were measured simultaneously. Chromatin immunoprecipitation (ChIP) assays were used to detect the effects of RSV on the recruitment of AR to its cognate element (ARE).
A ligand dependent co-activator for the human androgen receptor has been identified. The co-activator, named here ARA70, potentiates interaction between androgens and the receptor. The co-activator is useful as a tool in monitoring the androgenic/antiandrogenic effects of possible pharmaceuticals as well as environmental samples. The cDNA for co-activator has been cloned and sequenced.

Androgen receptor is a ligand-activated transcription factor and a validated drug target for all stages of prostate cancer. Antiandrogens compete with physiologic ligands for androgen receptor ligand-binding domain (LBD). High-throughput screening of a marine natural product library for small molecules that inhibit androgen receptor transcriptional activity yielded the furanoditerpenoid spongia-13(16),-14-dien-19-oic acid, designated terpene 1 (T1). Characterization of T1 and the structurally related semisynthetic analogues (T2 and T3) revealed that these diterpenoids have antiandrogen properties that include inhibition of both androgen-dependent proliferation and androgen receptor transcriptional activity by a mechanism that involved competing with androgen for androgen receptor LBD and blocking essential N/C interactions required for androgen-induced androgen receptor transcriptional activity. Structure-activity relationship analyses revealed some chemical features of T1 that are associated with

Prostate cancer remains the most common non-cutaneous malignancy among men worldwide. Prostate cancer is a complex disease, with many controversial aspects of management. Prostate cancer is an androgen dependent disease that initially responds but later becomes resistant to established therapies that reduce circulating testosterone levels (,50 ng/dL) or inhibit androgen binding to androgen receptor (AR). Reactivation of the disease despite castrate levels of testosterone represents a transition to the lethal phenotype of castration-resistant/recurrent prostate cancer (CRPC). This state is now recognized to be driven by AR signaling, in part due to overexpression of the androgen receptor itself. Enzalutamide (Xtandi®) is an oral AR antagonist that directly inhibits AR by irreversibly binding to the receptor. This interaction impairs AR nuclear translocation, DNA binding, and recruitment of co-activators. Preclinical studies have indicated that enzalutamide is a potent inhibitor and leads to ...
Typically, in vitro hazard assessments for the identification of endocrine disrupting compounds (EDCs), including those outlined in the EDSTAC Tier 1 Screening (T1S) protocols, utilize mammalian receptors. However, evidence exists that fish sex steroid hormone receptors differ from mammalian receptors both structurally and in their binding affinities for some steroids and environmental chemicals. Most of the binding information available to date has been conducted using cytosolic preparations from various tissues. We sought to compare competitive binding using rainbow trout androgen receptor alpha (rtAR) and human androgen receptor (hAR) expressed in transfected COS cells. In this system we can investigate the binding affinities of individual receptors without the potentially confounding effects of other steroid receptors present in cytosolic tissue extracts. Saturation ligand binding and Scatchard anaylsis using [3H]R1881, a synthetic androgen, revealed a KD of 0.24 nM for the rtAR. In the same ...

Selective androgen receptor modulators (SARMs) are a novel class of androgen receptor ligands. They are intended to exhibit the same kind of effects as androgenic drugs, like anabolic steroids, but be much more selective in their action, targeting particular tissues without any undesirable effects on others. While the main applications of these synthetic substances are for therapeutic purposes, they also have a high potential for misuse in veterinary practice and the sporting world. In order to guarantee for consumers with food from animal origin that it is free from any residues of such compounds, analytical strategies are required to ensure safe food and also to enable fair trade between producers ...
This single arm Phase II trial will assess the best overall response associated with enzalutamide in patients with AR-positive salivary cancers. Given that this will be one of the first prospective studies ever conducted for AR-positive salivary cancers, and there are currently no standard therapies known to be effective for this disease, the investigators will adopt a best overall response (BOR) of 5% as the null hypothesis and BOR of 20 % as the alternative hypothesis. In addition to response, this study will also evaluate the progression-free survival (PFS), overall survival (OS), adverse events, and will also try to identify molecular predictors of response by examining genomic and transcriptional elements of androgen receptor biology.. The primary and secondary objectives of the study:. Primary objective. To evaluate the rate of best overall response associated with enzalutamide in patients with AR-positive salivary cancers. Secondary objectives. ...
The androgen receptor (AR) is required for prostate cancer (PCa) survival and progression, and ablation of AR activity is the first line of therapeutic intervention for disseminated disease. While initially effective, recurrent tumors ultimately arise for which there is no durable cure. Despite the dependence of PCa on AR activity throughout the course of disease, delineation of the AR-dependent transcriptional network that governs disease progression remains elusive, and the function of AR in mitotically active cells is not well understood. Analyzing AR activity as a function of cell cycle revealed an unexpected and highly expanded repertoire of AR-regulated gene networks in actively cycling cells. New AR functions segregated into two major clusters: those that are specific to cycling cells and retained throughout the mitotic cell cycle (Cell Cycle Common), versus those that were specifically enriched in a subset of cell cycle phases (Phase Restricted). Further analyses identified previously
Overall, SARMs do not affect sex drive or sperm count.. As one of the distasteful side effects of steroids or other strong testosterone-enhancers, the negative effects of reduced sex drive and sperm count were on the top of the list when making SARMs. The producers of SARMs wanted to design a supplement that gave all the great benefits of steroids, while still specifically promoting full anabolic activity muscle and bone.. All this is to say that SARMs have been specifically designed to avoid those side effects of reduced sperm count or other sexual side effects with could lead to problems infertility. Plus, they are showing to have minimal effects on the prostate in general, which cant be said for most other steroids or prohormones. By avoiding high concentrations of anabolic steroids, scientists think SARMs will more effectively dodge the risk of throwing hormones wildly off balance.. In fact, SARMs are giving some surprising results during testing phases that look promising. Some SARMs, such ...

2. An effective body building supplement:. One needs not to be told that SR9009 will work wonders in improving the endurance, strength, muscle hypertrophy (growth), body metabolism, fat loss and sugar level of a person. It wont be surprising to see SR9009 offer the same benefit as Cardine (GW-501516). Considering the fact that Stenabolic is effective when used solo or stacked, this means it will be an excellent supplement which can be taken alongside any steroid or SARMS cycle, and will enhance a users performance when combined with Cardarine.. SR9009 (Stenabolic) Recommended Dosage:. The optimal dosages range from 20 to 30 milligrams (mgs) per day. However, there is one drawback - due to a very short half life, you will need to space it out throughout the day for the best balance of the active substance in the body. Thus, it is best to use stenabolic every 2-4 hours, depending on the exact dosage used. For example, when the daily dosage is 30 mgs, you can take 10 mgs every 4 hours.. SR9009 ...

Follistatin on Monkeys. The researchers just injected the gene follistatin (FS344) directly into the monkeys right thigh muscles. It has been shown that follistatin can block myostatin, a molecule that down-regulates muscle growth, but strengthens tendons. Eight weeks after the injection the circumference of the monkeys right thigh muscles, had on average gone up 15 percent compared with the left thigh. A study done on two of the monkeys showed that muscle strength in the right leg was increased by respectively 12 and 36 per cent compared to the untreated leg.. SARM a potentially safer steroid.

They are intended to have the same kind of effects as androgenic drugs like anabolic steroids but be much more selective in their action. None of the SARMs yet developed are truly selective for anabolic effects in muscle or bone tissues without producing any androgenic effects in tissues such as the prostate ...

N2 - Several regulatory concerns have hindered development of androgens as anabolic therapies, despite unequivocal evidence that testosterone supplementation increases muscle mass and strength in men; it induces hypertrophy of type I and II muscle fibers, and increases myonuclear and satellite cell number. Androgens promote differentiation of mesenchymal multipotent cells into the myogenic lineage and inhibit their adipogenic differentiation, by facilitating association of androgen receptors with β-catenin and activating T-cell factor 4. Meta-analyses indicate that testosterone supplementation increases fat-free mass and muscle ...
Doping control authorities and sports drug testing laboratories are frequently confronted with the illicit use of performance-enhancing therapeutics and therefore various analytical strategies have been developed to detect a misused drug and/or its metabolic product(s) in blood or urine specimens. Besides the administration of clinically approved drugs prohibited in sports,
A randomized double-blind phase 2 trial comparing the medications in 375 mCRPC patients showed that the 184 patients treated with enzalutamide had a significantly longer median progression-free survival (the primary trial endpoint) than the 191 bicalutamide recipients (15.7 vs. 5.8 months), reported investigator D. Robert Siemens, MD, of Queens University in Kingston, Ontario. This difference translated into a 56% decreased risk of progression. In addition, the median time to PSA progression was significantly longer in the enzalutamide than bicalutamide group (19.4 vs. 5.8 months). A 50% or greater PSA response was achieved in 82.1% of the enzalutamide group compared with 20.9% of the bicalutamide group. The enzalutamide group had a higher rate of serious adverse events (31.1% vs. 23.3 ...

Abstract: The 26S proteasome, which degrades ubiquitinated proteins, appears to contribute to the cyclical loading of androgen receptor (AR) to androgen response elements of target gene promoters; however, the mechanism whereby the 26S proteasome modulates AR recruitment remains unknown. Using yeast two-hybrid screening, we previously identified Tat-binding protein-1 (TBP-1), an adenosine triphosphatase of 19S regulatory particles of the 26S proteasome, as a transcriptional coactivator of thyroid hormone receptor. Independently, TBP-1-interacting protein (TBPIP) was also identified as a coactivator of several nuclear receptors, including AR. Here, we investigated whether TBP-1 could interact with and modulate transcriptional activation by AR cooperatively with TBPIP. TBP-1 mRNA was ubiquitously expressed in human tissues, including the testis and prostate, as well as in LNCaP cells. TBP-1 directly bound TBPIP through the amino-terminal domain possessing the leucine zipper structure. AR is ...
Bicalutamide should be used with caution in patients with moderate-to-severe hepatic impairment. Bicalutamide is extensively metabolized by the liver. Limited data in subjects with severe hepatic impairment suggest that excretion of bicalutamide may be delayed and could lead to further accumulation. Periodic liver function tests should be considered for hepatic-impaired patients on long-term therapy [see Warnings and Precautions (5.1)]. No clinically significant difference in the pharmacokinetics of either enantiomer of bicalutamide was noted in patients with mild-to-moderate hepatic disease as compared to healthy controls. However, the half-life of the R-enantiomer was increased approximately 76% (5.9 and 10.4 days for normal and impaired patients, respectively) in patients with severe liver disease (n=4). ...

Chronic inflammation is associated with advanced prostate cancer (PCa), although the mechanisms governing inflammation-mediated PCa progression are not fully understood. PCa progresses to an androgen independent phenotype that is incurable. We previously showed that androgen independent, androgen receptor negative (AR−) PCa cell lines have high p62/SQSTM1 levels required for cell survival. We also showed that factors in the HS-5 bone marrow stromal cell (BMSC) conditioned medium can upregulate p62 in AR+ PCa cell lines, leading us to investigate AR expression under those growth conditions. In this paper, mRNA, protein, and subcellular analyses reveal that HS-5 BMSC conditioned medium represses AR mRNA, protein, and nuclear accumulation in the C4-2 PCa cell line. Using published gene expression data, we identify the inflammatory cytokine, IL-1β, as a candidate BMSC paracrine factor to regulate AR expression and find that IL-1β is sufficient to both repress AR and upregulate p62 in multiple ...
Intracellular receptors (IRs) form a class of structurally-related genetic regulators scientists have named "ligand dependent transcription factors." R.M. Evans, Science, 240:889 (1988). Steroid receptors are a recognized subset of the IRs, including the progesterone receptor (PR) androgen receptor (AR), estrogen receptor (ER), glucocorticoid receptor (GR) and mineralocorticoid receptor (MR). Regulation of a gene by such factors requires both the IR itself and a corresponding ligand, which has the ability to selectively bind to the IR in a way that affects gene transcription ...
BACKGROUND We developed non-invasive, cell-based screening assays to rapidly and biologically assess factors that modulate prostate cancer growth and affect androgen receptor (AR) activity. METHODS LNCaP cells, which stably express enhanced green fluorescent protein (EGFP) either constitutively or upon AR activation, were treated with a variety of agents, and then monitored by fluorescence and MTS assays for dose-dependent changes in cell number and AR activity. RESULTS The assays were validated for rapid, fluorescence-based, quantitative measurement for the presence of growth and AR modulators. Using these assays, we found that osteoblast conditioned media (CM) enhanced prostate cancer cell growth, but not AR activity. After priming with androgen (|1 nM R1881), forskolin or the pesticide dichlorvos enhanced AR activation, whereas interleukin-6 (IL-6) inhibited it. CONCLUSION These non-destructive, cell-based assays enable rapid systematic monitoring of the effects of drugs or complex mixtures on

In prostate cancer, androgen deprivation therapy (ADT) enhances the cytotoxic effects of radiotherapy. This effect is associated with weakening of the DNA damage response (DDR) normally supported by the androgen receptor. As a significant number of patients will fail combined ADT and radiotherapy, we hypothesized that DDR may be driven by androgen receptor splice variants (ARV) induced by ADT. Investigating this hypothesis, we found that ARVs increase the clonogenic survival of prostate cancer cells after irradiation in an ADT-independent manner. Notably, prostate cancer cell irradiation triggers binding of ARV to the catalytic subunit of the critical DNA repair kinase DNA-PK. Pharmacologic inhibition of DNA-PKc blocked this interaction, increased DNA damage, and elevated prostate cancer cell death after irradiation. Our findings provide a mechanistic rationale for therapeutic targeting of DNA-PK in the context of combined ADT and radiotherapy as a strategy to radiosensitize clinically localized ...
Over the last few decades, scientists have witnessed a significant decline in worldwide amphibian populations. Many factors have been suggested to contribute to this decline, including endocrine disruption (by endocrine disrupting compounds or EDCs). Many anthropogenic chemicals have the potential to interfere with an organisms endocrine system, acting either as receptor agonists or antagonists, or by altering hormone metabolism. To determine the effects of EDCs, we must know an organisms normal functioning state. Thyroid hormone (TH) is the inducer of amphibian metamorphosis, the process of converting a tadpole into a frog. Sex steroid hormones, such as androgens (testosterone, and dihydrotestosterone), drive the development of secondary sexual characteristics after metamorphosis is initiated. Important interactions between TH and androgens have been demonstrated in various vertebrates, although the precise mechanism is unknown. The objective of this research is to investigate the nature of ...

  • However, because estrogens are made from androgens in the body, antiandrogens that suppress androgen production can cause low estrogen levels and associated symptoms like hot flashes, menstrual irregularities , and osteoporosis in premenopausal women. (wikipedia.org)
  • Evidence suggests that a growth factor released by PGCs, bone morphogenic protein 15 (bmp15), promotes female development by increasing expression of cyp19a1a, an aromatase enzyme that converts androgens to estrogens. (deepdyve.com)
  • Moreover, we found that androgen-independent cell lines were less sensitive to growth inhibition and cell death induced by SAHA than the androgen-responsive LNCaP cells ( 16 ). (aacrjournals.org)
  • Therefore, in this study, we investigated whether the sensitivity of the LNCaP prostate cancer cell line to SAHA is dependent on the presence of a functional androgen signaling axis and whether the combination of low doses of both SAHA and a specific androgen receptor (AR) antagonist would result in enhanced growth suppression and/or apoptosis.

  • Addition of exogenous androgen prevented the induction of cell death, indicating that suppression of androgen signaling was required for synergy. (aacrjournals.org)
  • Castration, therefore, does not suppress adrenal androgens and achieves a "hormone-reduced" rather than a "hormone-free" state, hence, the recent renaming of this stage of the disease as castration-resistant in preference to hormone-refractory. (aacrjournals.org)
  • Further mechanisms that can enhance AR activity and may contribute to AR activation and resistance to AR antagonists include increased expression of transcriptional coactivator proteins and activation of kinases and signal transduction pathways that can modulate AR function, including the protein kinase A, c-Src, cyclin-dependent kinase 1, Ras-Raf-mitogen-activated protein kinase (MAPK), and phosphatidylinositol 3-kinase pathways ( 12 - 17 ).
