Among Chinese soft-shelled turtles, Pelodiscus sinensis, males have a richer nutritional value and higher market price than females. All-male offspring were obtained by 17β-estradiol (E2). However, the molecular mechanisms of E2 inducing sexual reversal remain unclear. In this study, we cloned estrogen nuclear receptors (ERs) from P. sinensis investigated their expression profiles. We examined ...
In rats, the magnocellular neurons that produce vasopressin (VP) and oxytocin (OT) express estrogen receptor-beta (ER-beta). Physiological concentrations of estrogen (E2) inhibit N-methyl-D-aspartate (NMDA)-stimulated VP and OT release from explants of the hypothalamo-neurohypophyseal system (HNS). To determine whether ER-beta mediates inhibition by E2, HNS explants were perifused with and with...
We have generated replication-competent (VSV-C/E1/E2) and nonpropagating (VSVDeltaG-C/E1/E2) vesicular stomatitis virus (VSV) contiguously expressing the structural proteins of hepatitis C virus (HCV; core [C] and glycoproteins E1 and E2) and report on their immunogenicity in murine models. VSV-C/E1/E2 and VSVDeltaG-C/E1/E2 expressed high levels of HCV C, E1, and E2, which were authentically po...
ویروس هرپس سیمپلکس تیپ یک (hsv-1) ، ویروسی انولوپ دار با dna دو رشته ای خطی است که بیماری های مختلفی در انسان ایجاد می کند که از بیماری های خفیف در بسیاری از بیماران تا بیماری های تهدیدکننده زندگی در نوزادان و افراد با ایمنی سازشکار دیده می شود. این ویروس حداقل 11 گلیکوپروتئین را کد می کند که گلیکوپروتئین d نقش مهمی درعفونت زایی و پاتوژنز ویروس دارد. دراین پژوهش ، ابتدا hsv-1 تک...
The E2 protein is expressed in the early stage of human papillomavirus (HPV) infection that is associated with cervical lesions. This protein plays important roles in regulation of viral replication and transcription. To characterize the role of E2 protein in modulation of cellular gene expression in HPV infected cells, genome-wide expression profiling of human primary keratinocytes (HPK) harbo...
Optimal care for breast cancer patients undergoing aromatase inhibitor (AI) treatment is ensured when estradiol (E2) levels are adequately suppressed. To assess treatment efficacy accurately, it is important to measure the serum E2 levels using a well validated assay method with high sensitivity and specificity. This translates into the urgent need to evaluate various E2 immunoassay kits, which...
The papillomavirus E2 proteins regulate viral transcription and replication and therefore play a central role in the viral life-cycle. In BPV1, the full-length E2 gene product is a transcriptional transactivator that activates transcription from several viral promoters by binding to E2 binding sites located within enhancer elements in the LCR (reviewed in [68,75]). BPV1 also encodes two shorter...
OBJECTIVES Estrogen (E2) has neuroprotective effects on blood-brain-barrier (BBB) after traumatic brain injury (TBI). In order to investigate the roles of estrogen receptors (ERs) in these effects, ER-α antagonist (MPP) and, ER-β antagonist (PHTPP), or non-selective estrogen receptors antagonist (ICI 182780) were administered. MATERIALS AND METHODS Ovariectomized rats were divided into 10 gro...
Stimulatory heterotrimeric G protein (Gs) transduces signals from various cell-surface receptors to adenylyl cyclases, which generate cAMP. The alpha subunit of Gs (Gsalpha) is encoded by GNAS (Gnas in mice), and heterozygous Gsalpha inactivating mutations lead to Albright hereditary osteodystrophy. The in vivo role of Gsalpha in skeletogenesis is largely unknown, because of early embryonic let...
