Effects of spinal cord injury on spermatogenesis and the expression of messenger ribonucleic acid for Sertoli cell proteins in rat Sertoli cell-enriched testes. (1/242)

The study was an examination of the effects of spinal cord injury (SCI) on spermatogenesis and Sertoli cell functions in adult rats with Sertoli cell-enriched (SCE) testes. The effects of SCI on the seminiferous epithelium were characterized by abnormalities in the remaining spermatogenic cells during the first month after SCI. Three days after SCI, serum testosterone levels were 80% lower, while serum FSH and LH levels were 25% and 50% higher, respectively, than those of sham control SCE rats. At this time, the levels of mRNA for androgen receptor (AR), FSH receptor (FSH-R), and androgen-binding protein (ABP) were normal whereas those for transferrin (Trf) had decreased by 40%. Thereafter, serum testosterone levels increased, but they remained lower than those of the sham control rats 28 days after SCI; and serum FSH and LH levels returned to normal. The levels of mRNA for AR, ABP, and Trf exhibited a biphasic increase 7 days after SCI and remained elevated 28 days after SCI. FSH-R mRNA levels were also elevated 90 days after SCI. Unexpectedly, active spermatogenesis, including qualitatively complete spermatogenesis, persisted in > 40% of the tubules 90 days after SCI. These results suggest that the stem cells and/or undifferentiated spermatogonia in SCE testes are less susceptible to the deleterious effects of SCI than the normal testes and that they were able to proliferate and differentiate after SCI. The presence of elevated levels of mRNA for Sertoli cell FSH-R and AR, as well as of that for the Sertoli cell proteins, in the SCE testes during the chronic stage of SCI suggests a modification of Sertoli cell physiology. Such changes in Sertoli cell functions may provide a beneficial environment for the proliferation of the stem cells and differentiation of postmeiotic cells, thus resulting in the persistence of spermatogenesis in these testes.  (+info)

Toll receptor-mediated Drosophila immune response requires Dif, an NF-kappaB factor. (2/242)

The induction of immunity genes in Drosophila has been proposed to be dependent on Dorsal, Dif, and Relish, the NF-kappaB-related factors. Here we provide genetic evidence that Dif is required for the induction of only a subset of antimicrobial peptide genes. The results show that the presence of Dif without Dorsal is sufficient to mediate the induction of drosomycin and defensin. We also demonstrate that Dif is a downstream component of the Toll signaling pathway in activating the drosomycin expression. These results reveal that individual members of the NF-kappaB family in Drosophila have distinct roles in immunity and development.  (+info)

Characterization of lipid efflux particles generated by seminal phospholipid-binding proteins. (3/242)

We reported recently that the choline phospholipid-binding proteins (BSP-A1/-A2, BSP-A3 and BSP-30-kDa) of bovine seminal plasma (BSP) stimulate cholesterol and choline phospholipid efflux from fibroblasts. In this study, we characterized the lipid efflux particles generated by BSP proteins. The density gradient ultracentrifugation of the efflux medium from radiolabeled fibroblasts incubated with BSP proteins showed a single peak of [3H]cholesterol between density (d) 1.12 and 1.14 g/ml, which is in the range of high-density lipoproteins. Size-exclusion chromatographic and immunoblot analysis revealed that the efflux particles have a large size equal to or bigger than very low-density lipoproteins and contained BSP proteins. Lipid analysis of density gradient and gel filtration fractions from efflux medium of simultaneously labeled fibroblasts ([3H]cholesterol and [3H]choline) incubated with BSP proteins showed that the efflux particles were homogeneous and composed of cholesterol and choline phospholipids. The lipid particles contained BSP proteins, cholesterol and choline phospholipids in molar ratio of 0.05:1.21:1, respectively. Agarose gel electrophoresis showed that the BSP-generated lipid particles had a gamma migration pattern which is slower than low-density lipoproteins. The sonication of cholesterol and BSP proteins followed by gel filtration chromatographic analysis indicated no direct binding of cholesterol to BSP proteins. These results taken together indicate that BSP proteins induce a concomitant cholesterol and choline phospholipid efflux and generate large protein-lipid particles.  (+info)

Selective activation of the probasin androgen-responsive region by steroid hormones. (4/242)

Glucocorticoid and androgen receptors have been shown to function through the same palindromic glucocorticoid response element (GRE) and yet have differential effects on gene transcription. In this study, we examined the functional and structural relationship of the androgen and glucocorticoid receptors with the androgen responsive region (ARR) of the probasin (PB) gene containing two androgen receptor binding sites, ARBS-1 and ARBS-2. Transfection studies indicated that one copy of each cis-acting DNA element was essential for maximal androgen-induced chloramphenicol acetyltransferase (CAT) activity and that androgen selectivity was maintained when multiple copies of the minimal wild type (wt) androgen responsive region containing both ARBS-1 and ARBS-2 (-244 to -96) were subcloned in front of the thymidine kinase promoter. Furthermore, replacing the androgen response region with 1, 2 or 3 copies of either ARBS-1 or ARBS-2 restored less than 4% of the biological activity seen with the wt PB ARR. Multiple copies of either ARBS-1 or ARBS-2 did not result in glucocorticoid-induced CAT gene activity. By comparison, 1 or 2 copies of the tyrosine aminotransferase (TAT) GRE, as well as the mouse mammary tumour virus GRE, were strong inducers of CAT activity in response to both androgen and glucocorticoid treatment. In addition, band shift assays demonstrated that although the synthetic glucocorticoid receptor, GR-DNA binding domain (GR-DBD), and the synthetic androgen receptor, AR2, could interact with the TAT GRE (dissociation constants Kd of 63.9 and 14.1 respectively), only AR2 but not GR-DBD binding could be detected on ARBS-1 and ARBS-2. Our findings provide further evidence that androgen-induced regulation of gene transcription can occur through androgen-specific DNA binding sites that are distinct from the common GRE.  (+info)

The addition of adenovirus type 5 region E3 enables calydon virus 787 to eliminate distant prostate tumor xenografts. (5/242)

CV787, a novel highly prostate-specific replication-competent adenovirus with improved efficacy, was constructed. CV787 contains the prostate-specific rat probasin promoter, driving the adenovirus type 5 (Ad5) E1A gene, and the human prostate-specific enhancer/promoter, driving the E1B gene. To improve efficacy, we constructed CV787 such that it also contains the entire Ad5 E3 region. CV787 replicates in prostate-specific antigen (PSA)+ cells as well as wild-type adenovirus, but in PSA- cells, CV787 replicates 10(4)-10(5) times less efficiently. CV787 destroys PSA+ prostate cancer cells 10,000 times more efficiently than PSA- cells. Incorporation of the Ad5 E3 region significantly improves the target cell killing ability or efficacy of CV787. In nu/nu mice carrying s.c. LNCaP xenografts, a single i.v. tail vein injection of CV787 eliminates 300-mm3 tumors within 4 weeks. CV787 could be a powerful therapeutic for human metastatic prostate cancer.  (+info)

Reduced nucleotide variability at an androgen-binding protein locus (Abpa) in house mice: evidence for positive natural selection. (6/242)

Previous work has shown that the gene for the alpha subunit of androgen-binding protein, Abpa, may be involved in premating isolation between different subspecies of the house mouse, Mus musculus. We investigated patterns of DNA sequence variation at Abpa within and between species of mice to test several predictions of a model of neutral molecular evolution. Intraspecific variation among 10 Mus musculus domesticus alleles was compared with divergence between M. m. domesticus and M. caroli for Abpa and two X-linked genes, Glra2 and Amg. No variation was observed at Abpa within M. m. domesticus. The ratio of polymorphism to divergence was significantly lower at Abpa than at Glra2 and Amg, despite the fact that all three genes experience similar rates of recombination. Interspecific comparisons among M. m. domesticus, Mus musculus musculus, Mus musculus castaneus, Mus spretus, Mus spicilegus, and Mus caroli revealed that the ratio of nonsynonymous substitutions to synonymous substitutions on a per-site basis (Ka/Ks) was generally greater than one. The combined observations of no variation at Abpa within M. m: domesticus and uniformly high Ka/Ks values between species suggest that positive directional selection has acted recently at this locus.  (+info)

Heterotopic endochondrial ossification with mixed tumor formation in C3(1)/Tag transgenic mice is associated with elevated TGF-beta1 and BMP-2 expression. (7/242)

Transgenic mice which express the simian virus 40 large T-antigen (Tag) under the regulatory control of the hormone responsive rat C3(1) gene develop unusual lesions of heterotopic bone growth associated with mixed tumor formation arising from eccrine sweat glands found only in the foot pads of mice, ischiocavernosus muscle adjacent to bulbourethral glands and occasionally the salivary and mammary glands. These lesions are very similar to mixed tumors arising in several types of human cancers. Based upon electron microscopic examination and immunocytochemical analyses of cellular differentiation markers, the mixed proliferative lesions in this transgenic mouse model begin with the Tag-induced proliferation of epithelial and myoepithelial cells. The proliferation of these two types of cells results in hyperplasia and adenomatous transformation of the epithelial component, whereas the proliferating myoepithelial cells undergo metaplasia to form chondrocytes which deposit extracellular matrix, including collagen fibers. Cartilage develops focally between areas of epithelial proliferation and subsequently ossifies through a process of endochondrial bone formation. The metaplasia of myoepithelial cells to chondrocytes appears to require the inductive interaction of factors produced by the closely associated proliferating epithelial cells, including members of the TGF-beta superfamily. We demonstrate that TGF-beta1 protein accumulates in the extracellular matrix of the lesions, whereas RNA in situ hybridization reveals that BMP-2, another strong inducer of heterotopic bone formation, is overexpressed by the proliferating epithelial cells during the development of ectopic bone. The formation of sarcomatous tumors within the mixed tumors appears to be androgen-dependent and more frequent in mice lacking a normal allele of p53. This process of cartilage and bone induction may mimic epithelial-mesenchymal interactions which occur during embryonic bone formation. These transgenic mice may provide new insights into the processes of ectopic endochondrial bone formation associated with mixed tumor formation and serve as a useful model for human heterotopic bone disease.  (+info)

Mice without phosphatidylcholine transfer protein have no defects in the secretion of phosphatidylcholine into bile or into lung airspaces. (8/242)

Phosphatidylcholine transfer protein (Pc-tp) is a highly specific carrier of phosphatidylcholine (PC) without known function. Proposed functions include the supply of PC required for secretion into bile or lung air space (surfactant) and the facilitation of enzymatic reactions involving PC synthesis or breakdown. To test these functions, we generated knock-out mice unable to make Pc-tp. Remarkably, these mice are normal and have no defect in any of the postulated Pc-tp functions analyzed. The lipid content and composition of the bile, as well as lung surfactant secretion and composition, of Pc-tp (-/-) mice, is normal. The lack of a Pc-tp contribution to biliary lipid secretion is in agreement with our finding that Pc-tp is down-regulated in adult mouse liver: whereas Pc-tp is abundant in the liver of mouse pups, Pc-tp levels decrease > 10-fold around 2 wk after birth, when bile formation starts. In adult mice, Pc-tp levels are high only in epididymis, testis, kidney, and bone marrow-derived mast cells. Absence of Pc-tp in bone marrow-derived mast cells does not affect their lipid composition or PC synthesis and degradation. We discuss how PC might reach the canalicular membrane of the hepatocyte for secretion into the bile, if not by Pc-tp.  (+info)

The synthesis of androgen-binding protein by cultured Sertoli cells is increased by insulin, retinol, follitropin and testosterone. Only follitropin will stimulate an increase in cyclic AMP in these cells, yet each agent individually increased the synthesis of androgen-binding protein in short-term cultures. For long-term culture of Sertoli cells follitropin, testosterone, insulin, and retinol appeared to act synergistically to prolong the ability of the cells to secrete androgen-binding protein. These are the first reported results which suggest an action of insulin and retinol directly on Sertoli cells even though the importance of both factors in male reproduction is known.. ...

In order to study the individual steps involved in the import of phosphatidylcholine (PC) into rat liver mitochondria, a number of PC analogues were introduced into the outer membrane of isolated mitochondria. Two fluorescent PC species, i.e. 1-palmitoyl-2-(16-bimanylthio)hexadecanoyl-PC (bimane-PC) and 1-palmitoyl-2-(10-pyrene)decanoyl-PC (pyrene-PC), and one radiolabeled PC species, i.e. 1-palmitoyl-2-[1-14C]oleoyl-PC (14C-POPC), were studied. The PC analogues were introduced from small unilamellar vesicles with the use of PC-specific transfer protein. The amount of PC imported was quantified by reisolation of the mitochondria. Import of the fluorescent PC species was monitored by on-line fluorescence spectroscopy. The distribution of the newly inserted PC between the outer and the inner membrane was assessed by separation of the two membranes using digitonin treatment. All analogues tested remained exclusively localized in the outer membrane thereby suggesting that additional ...

Gastric cancer (GC) is a threat to human health with increasing incidence and mortality worldwide. Down-regulation or absence of RAF kinase inhibitor protein (RKIP) was associated with the occurrence, differentiation, invasion, and metastasis of GC. This study aims to investigate the molecular mechanisms and biological functions of RKIP in the GC biology. The fusion expression plasmid pcDNA3.1-RKIP-3xFLAG was transfected into SGC7901 cells, the RKIP fusion proteins were purified with anti-flag M2 magnetic beads, and the RKIP-interacting proteins were identified with tandem mass spectrometry (MS/MS), and were analyzed with bioinformatics tools. Western blot and co-immunoprecipitation were used to confirm the interaction complex. A total of 72 RKIP-interacting proteins were identified by MS/MS. Those proteins play roles in enzyme metabolism, molecular chaperoning, biological oxidation, cytoskeleton organization, signal transduction, and enzymolysis.

Intense RKIP staining was observed in normal milk duct epithelial cell, whereas RKIP expression was downregulated in primary breast carcinomas. The consistent yet cystine variable downregulation of RKIP expression in primary breast carcinomas prompted us to examine whether there was a correlation between the reduction of RKIP expression and the Captopril propensity to metastasize and weakly positive in of, weakly positive in of cases. This distribution of RKIP downregulation is statistically not significant but suggestive of a trend that primary tumors with reduced levels of RKIP expression have a higher tendency to metastasize.Raf kinase inhibitor protein expression is significantly diminished in metastatic breast cancer.RKIP expression in the nodepositive tumors was predominantly moderate in intensity. By contrast, in the matched lymph node metastases obtained from the same patients, RKIP expression was considerably diminished were weakly positive for RKIP expression, of cases were moderately ...
Gastric cancer is a leading cause of cancer-related mortality, and the presence of lymph node metastasis an important prognostic factor. Downregulation of RKIP has been associated with tumor progression and metastasis in several types of neoplasms, being currently categorized as a metastasis suppressor gene. Our aim was to determine the expression levels of RKIP in gastric tissues and to evaluate its impact in the clinical outcome of gastric carcinoma patients. RKIP expression levels were studied by immunohistochemistry in a series of gastric tissues. Overall, we analysed 222 non-neoplastic gastric tissues, 152 primary tumors and 42 lymph node metastasis samples. We observed that RKIP was highly expressed in similar to 83% of non-neoplastic tissues (including normal tissue and metaplasia), was lost in similar to 56% of primary tumors and in similar to 90% of lymph node metastasis samples. Loss of RKIP expression was significantly associated with several markers of poor clinical outcome, ...

733 PSK has been shown to have immunoaugmenting effects in several preclinical and clinical studies carried out mainly in Japan. In the TRAMP model the tumor develops after the SV40 T-antigen transgene expression which is controlled by the rat probasin promoter in the C57BL/6 background. This model mimics the development of human prostate tumors in the sense that prostate intraepithelial neoplasia (PIN) is seen early, by 8 weeks after birth in mice, with dorsolateral prostate invasive neoplasia evolving progressively thereafter. The hypothesis is being tested that augmentation of innate and early adaptive immunity by chemical structures may retard the development of the disease: PSK is the first agent used to this end. Treatment is given i.p. starting at 4 weeks after birth; mice are sacrificed at 12 and 18 weeks, the macroscopic occurrence of tumors is recorded, as is the weight of the prostate. Body weights are also recorded. Histological evaluation of prostate lobes allows grading of the ...
This paper examines the influence of the RAF Kinase Inhibitor Protein (RKIP) on the Extracellular signal Regulated Kinase (ERK) singalling pathway through modelling in a Morkovian process algebra, PEPA. Two models of the system are presented, a readgent-centric view and a pathway-centric view. The models capture functionality at the level of subpathway, rather than at a molecular level. Each model affords a different perspective of the pathway and analysis. We domonstrate the two models to be formally equivalent using the timing-aware bisimulation defined over PEPA models and discuss the biological significance ...
Polyene phosphatidylcholine is an unsaturated version of phosphatidylcholine which is derived from natural sources such as soybeans, eggs, sunflowers, mustard, etc. It is interchangeably mentioned as lecithin which is a different chemical moiety. It has a vital role in the transfer of phosphatidylcholine transfer protein (PCTP) within cell membranes and is the activation of enzymes having significance in the metabolic functions of the liver.. Liver diseases are reigning the clinical application segment for the polyene phosphatidylcholine market. According to the latest statistics provided by the National Institute of Health (NIH), it is estimated that approximately 50 million people worldwide are suffering from chronic liver disease. Additionally, the growing incidence of hepatitis B infection among the adult population across the globe further accelerates the market growth. Dietary supplements are gaining immense popularity since the last 2 decades on account of the rising public health ...

Phosphatidylcholine transfer protein (PC-TP) is a phospholipid-binding protein that is enriched in liver and that interacts with thioesterase superfamily member 2 (THEM2). Mice lacking either protein exhibit improved hepatic glucose homeostasis and are resistant to diet-induced diabetes. Insulin receptor substrate 2 (IRS2) and mammalian target of rapamycin complex 1 (mTORC1) are key effectors of insulin signaling, which is attenuated in diabetes. We found that PC-TP inhibited IRS2, as evidenced by insulin-independent IRS2 activation after knockdown, genetic ablation, or chemical inhibition of PC-TP. In addition, IRS2 was activated after knockdown of THEM2, providing support for a role for the interaction of PC-TP with THEM2 in suppressing insulin signaling. Additionally, we showed that PC-TP bound to tuberous sclerosis complex 2 (TSC2) and stabilized the components of the TSC1-TSC2 complex, which functions to inhibit mTORC1. Preventing phosphatidylcholine from binding to PC-TP disrupted ...
The production of testicular androgen-binding protein (ABP), as a measure of Sertoli cell function, was studied after unilateral or bilateral experimental cryptorchidism in adult rats. Two or 4 weeks after the testis had been translocated to the abdomen, no major changes were found in the concentration of ABP per mg protein, although there was a marked and progressive decrease in ABP content per testis. However, the rate of ABP production was greatly decreased, as measured by the accumulation of ABP during 16-h ligation of the efferent ducts or by the production of ABP by testis mince in an in vitro system. This indicates that the Sertoli cell function is severly impaired by the intra-abdominal position. ...
Foetal steroid binding protein (FSBP) is a normal constituent of adult human serum; in vivo it appears to influence the degree of steroid binding to albumin rather than acting primarily as a high affinity saturable binding protein. Serum levels are elevated in patients with parenchymal liver disease, hepatic malignancy and in those with non-metastatic breast cancer. That FSBP is protective against the development of breast carcinoma is however supported by a comparison of healthy women from racial groups at differing risk of this malignancy in which higher levels are found in those at lower risk. This hypothesis and the possible links between FSBP and primary hepatocellular carcinoma are further examined.. ...
The ORPs (oxysterol-binding-protein-related proteins) constitute an enigmatic family of intracellular lipid receptors that are related through a shared lipid binding domain. Emerging evidence suggests that ORPs relate lipid metabolism to membrane transport. Current data imply that the yeast ORP Kes1p is a negative regulator of Golgi-derived vesicular transport mediated by the essential phosphatidylinositol/phosphatidylcholine transfer protein Sec14p. Inactivation of Kes1p function allows restoration of growth and vesicular transport in cells lacking Sec14p function, and Kes1p function in this regard can be complemented by human ORP1S (ORP1 short). Recent studies have determined that Kes1p and ORP1S both bind phospholipids as ligands. To explore the function of distinct linear segments of ORP1S in phospholipid binding and vesicular transport regulation, we generated a series of 15 open reading frames coding for diagnostic regions within ORP1S. Purified versions of these ORP1S deletion proteins ...
Transgenic mice. Wild-type C57BL/6 mice and TRAMP TG C57BL/6 mice expressing the SV40 Tag controlled by rat probasin regulatory elements were purchased from The Jackson Laboratory (Bar Harbor, ME). Female LADY (12T-10) TG mice were obtained from Dr. Robert J. Matusik (Vanderbilt Prostate Center, Nashville, TN). We previously described development of FVB/N TG mice in which the Rosa26 promoter drives ubiquitous expression of the human FoxM1b cDNA transgene in all cell types ( 35). Rosa26-FoxM1b TG mice were bred with TRAMP or LADY TG mice to generate TRAMP/Rosa26-FoxM1b and LADY/Rosa26-FoxM1b double TG mice. Mice were sacrificed at ∼90 or 165 days of age for TRAMP single or double TG mice and at ∼120 or 150 days of age for LADY single and double TG mice. Prostate tissues were either used to prepare total RNA with RNA STAT-60 (Tel-Test B, Inc., Friendswood, TX) or fixed, paraffin embedded, and sectioned for morphologic examination following histologic staining with H&E or for ...
The available data demonstrate that even in universal metabolic pathways, some species-specific regulatory features of structural genes are present. For instance, in the anthocyanin biosynthesis pathway (ABP), genes may be regulated by ABP-specific regulatory factors, and their expression levels may be strongly associated with anthocyanin pigmentation, or they may be expressed independently of pigmentation. A dataset of orthologous ABP genes (Chs, Chi, F3h, F3h, Dfr, Ans) from monocot and dicot plant species that have distinct gene regulation patterns and different types of pollination was constructed to test whether these factors affect the evolution of the genes. Using a maximum likelihood approach, we demonstrated that although the whole set of the ABP genes is under purifying selection, with greater selection acting on the upstream genes than on the downstream genes, genes from distinct groups of plant species experienced different strengths of selective pressure. The selective pressure on the

The dorsoventral pattern of the Drosophila embryo is mediated by a gradient of nuclear localization of the dorsal protein which acts as amorphogen. Establishment of the nuclear concentration gradient of dorsal protein requires the activities of the 10 maternal dorsal group genes whose function results in the positive regulation of the nuclear uptake of the dorsal protein. Here we show that in contrast to the dorsal group genes, the maternal gene cactus acts as a negative regulator of the nuclear localization of the dorsal protein. While loss of function mutations of any of the dorsal group genes lead to dorsalized embryos, loss of cactusfunction results in a ventralization of the body pattern. Progressive loss of maternal cactus activity causes progressive loss of dorsal pattern elements accompanied by the expansion of ventrolateral and ventral anlagen. However, embryos still retain dorsoventral polarity, even if derived from germline clones using the strongest available, zygotic lethal cactus ...

Key words. Methylation of DNA in CpG-rich islands is a key event in the regulation of tissue- and context-specific gene expression. Thereby, DNA methyltransferase 3A (DNMT3A) plays a pivotal role by converting cytosine to 5-methylcytosine.1 Recently, DNMT3A mutations have been described at high frequency in acute myeloid leukemia (AML), particularly with a monocytic pheno- type.2-4 In in vitro assays, mutated DNMT3A induced aberrant DNA methylation and promoted cellular proliferation. RAF kinase inhibitor protein (RKIP) negatively regulates the RAS-mitogen activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) signaling pathway.5 Several solid neoplasms show decreased or absent expression of RKIP and its role as a metastasis suppressor has been firmly established in animal models and studies of human tumors.5 We recently demonstrated that RKIP acts as a tumor suppressor in hematopoietic cells and that loss of RKIP expression occurs frequently in AML.6,7 Similar to mutated ...
Several pathways could be involved in these mechanisms including activation of anti-apoptotic factors, inactivation of pro-apoptotic effectors, and/or reinforcement of Compound C mouse survival signals [122]. Based on an understanding of their characteristics, the refractory response of CSCs to drugs and radiation treatments may be attributed to: drug effluxion glutathione (GSH) system apoptosis; enrichment of CSCs during disease progression tumor dormancy and CSC quiescence Drug effluxion It can be caused by an altered uptake or efflux of drug in the target. cell. Platinum compounds enter the cell, primarily by passive diffusion, however several different ways have been described such as copper transporter proteins (CTR), organic cation transporters (OCTs) from de SLC22 family, ATP-binding cassette (ABC) multidrug transporters, copper-transporting ATPases, and multidrug and toxin extrusion from the SLC47 subfamily members that might Trichostatin A clinical trial facilitate the active efflux of ...

  • Independently, TBP-1-interacting protein (TBPIP) was also identified as a coactivator of several nuclear receptors, including AR. (scialert.net)
  • Although PIAS family proteins have been shown to play roles in SUMO-1 conjugation ( 6 -11 ) and in the regulations of STAT ( 12 , 13 ), nuclear receptors ( 4 , 5 , 14 -17 ), and K channels ( 18 ), the contribution of DJ-1 to such functions is not clear. (aacrjournals.org)
  • Moreover, gene families, such as those containing olfactory or vomeronasal receptors, immunoglobulin domain-containing proteins, or cytochromes P450 that are expanded in one lineage are often expanded in another. (beds.ac.uk)
  • In addition to this transcriptional genomic action, androgens and other steroid hormones like progesterone and estrogen can exert rapid nongenomic effects that are not mediated through nuclear receptors, but rather initiated at the plasma membrane, presumably through surface receptors ( 3 , 4 ). (aacrjournals.org)
  • Like progesterone (PR) and estrogen (ER) receptors, AR can interact with the intracellular tyrosine kinase c-Src to activate the mitogen-activated protein kinase (MAPK) pathway ( 5 , 6 ). (aacrjournals.org)
  • Bicalutamide binds to proteins called androgen receptors, which are found in some prostate cancer cells. (cancer.gov)
  • Complementary DNAs (cDNAs) encoding androgen receptors were obtained from human testis and rat ventral prostate cDNA libraries. (sciencemag.org)
  • The amino acid sequence deduced from the nucleotide sequences of the cDNAs indicated the presence of a cysteine-rich DNA-binding domain that is highly conserved in all steroid receptors. (sciencemag.org)
  • In some cell types testosterone interacts directly with androgen receptors while in others testosterone is converted by 5-alpha-reductase to dihydrotestosterone, an even more potent agonist for androgen receptor activation. (thefullwiki.org)
  • The primary mechanism of action for androgen receptors is direct regulation of gene transcription . (thefullwiki.org)
  • Androgen receptors interact with other proteins in the nucleus resulting in up or down regulation of specific gene transcription . (thefullwiki.org)
  • [ 11 ] Thus, changes in levels of specific proteins in cells is one way that androgen receptors control cell behavior. (thefullwiki.org)
  • More recently, androgen receptors have been shown to have a second mode of action. (thefullwiki.org)
  • As has been also found for other steroid hormone receptors such as estrogen receptors , androgen receptors can have actions that are independent of their interactions with DNA. (thefullwiki.org)
  • [ 6 ] [ 12 ] Androgen receptors interact with certain signal transduction proteins in the cytoplasm. (thefullwiki.org)
  • Androgen binding to cytoplasmic androgen receptors can cause rapid changes in cell function independent of changes in gene transcription, such as changes in ion transport . (thefullwiki.org)
  • Regulation of signal transduction pathways by cytoplasmic androgen receptors can indirectly lead to changes in gene transcription, for example, by leading to phosphorylation of other transcription factors. (thefullwiki.org)
  • Another connection is that luteinizing hormone and follicle stimulating hormone carry out their duties by triggering the actions of second messengers once they bind to cell receptors in the gonads. (wisegeek.com)
  • For this to happen, these hormones have to bind to androgen receptors, proteins located mostly in the cytoplasm of prostate cells. (news-medical.net)
  • This is what we believe the molecules we identified are doing to androgen receptors in a prostate tumor,' said Verjovski-Almeida, who is also a professor in the University of São Paulo's Chemistry Institute (IQ-USP). (news-medical.net)
  • The next step was to find out whether these lncRNAs interacted with androgen receptors. (news-medical.net)
  • We detected more than 600 lncRNAs bound to androgen receptors in prostate tumors. (news-medical.net)
  • Androgen receptors are known to be capable of binding to more than 10,000 different genome sites upon migrating to cell nuclei. (news-medical.net)

  • Winstrol binds well with androgen receptors. (namhaihotel.com)
  • It does not bind well with estrogen receptors and helps avoid water retention. (namhaihotel.com)
  • As with other nuclear receptors, AR has three distinct domains: an N-terminal transactivation domain (NTD), a central DNA binding domain, and a C-terminal ligand binding domain (LBD). (pubmedcentralcanada.ca)
  • The compound in HMG-Xtreme binds to muscle androgen receptors causing increased protein synthesis rates. (anabolicminds.com)
  • This means that HMG-Xtreme only binds to 17β-estradiol receptors in certain tissues such as mammary (breast). (anabolicminds.com)
  • Some chemicals do this by binding to receptors, such as the estrogen and androgen receptors. (fda.gov)
  • The testosterone binds to androgen receptors and causes increased protein synthesis. (energymanagertraining.com)
  • When taken into the cell, it can bind to the cytoplasmic estrogen receptors, and activate genes related to estrogen, tricking cells into thinking they are in an environment containing estrogen when they are not. (igem.org)
  • this is a small sequence of DNA that the receptors can specifically bind once they are dimerized (3). (igem.org)
  • Two of these carrier proteins, testicular androgen-binding protein (ABP) and plasma sex hormone-binding globulin (SHBG), are encoded by the same gene, but differ in glycosylation and possibly amino acid sequence. (duke.edu)
