BACKGROUND Acute-on-chronic hepatitis B liver failure (ACHBLF) is an acute deteriorating liver disease and rapidly progresses to multiple organ failure. There is currently no adequate accurate predictive models of ACHBLF prognosis. AIMS To identify the methylation frequency of the estrogen receptor 1 (ESR1) promoter in ACHBLF and analyze the associated prognostic significance. METHODS Methy...
PURPOSE To assess the prognostic and predictive value of circulating ESR1 mutation and its kinetics before and after progression on aromatase inhibitor (AI) treatment. PATIENTS AND METHODS ESR1 circulating D538G and Y537S/N/C mutations were retrospectively analyzed by digital droplet PCR after first-line AI failure in patients treated consecutively from 2010 to 2012 for hormone receptor-posit...
چکیده مقدمه: جهش‌های ژنتیکی با توجه به نقش غیرقابل انکاری که در پیدایش بیماری‌ها داشته و با تاثیر بر روی کنش‌های بعدی بیماری، موجب آسیب‌های بدخیم در پستان می‌شوند. از آن جمله، جهش نقطه‌ای در ژن گیرنده استروژن α(ESR1)، مانند G908A (لیزین 303 آرژنین) سبب تکثیر بی‌رویه سلول‌های حساس به استروژن و رشد تومور در پستان می‌شود. در این تحقیق ما به شناسایی و غربالگری این جهش در میان زنان ایرانی مبتلا ب...
PURPOSE There were a lot of reports regarding associations of polymorphisms in the estrogen receptor α (ESR1). with many disorders. But, those with constitutional delay of growth and puberty (CDGP) are not known. Our aim is to find out any association between CDGP and ESR1. METHODS In a total of 27 subjects, we compared 7 CDGP patients with 20 healthy controls with their heights and sexual ma...
Multiparametric duplex real-time nucleic acid sequence-based amplification assay for mRNA profiling.
Nucleic acid sequence-based amplification (NASBA) is a sensitive isothermal transcription-based amplification method. We have developed real-time NASBA assays to detect mRNA coding for the estrogen receptor alpha (ESR1) and the progesterone receptor (PGR) in breast tumors by means of duplex reactions using cyclophilin B (PPIB) as the normalizing gene. Both the ESR1/PPIB and PGR/PPIB duplex NASB...
Oestrogen receptors (ESRs) regulate the growth and differentiation of normal ovarian epithelia. However, to date their role as biomarkers in the clinical setting of ovarian cancer remains unclear. In view of potential endocrine treatment options, we tested the role of ESR1 mRNA expression in ovarian cancer in the context of a neo-adjuvant chemotherapy trial. Study participants had epithelial ov...
Comorbidty is common among psychiatric disorders including obsessive-compulsive disorder and schizophrenia with a high rate. Many studies suggested that the disorders may have same etiological bases. In this regard, shared pathways of glutamate, dopaminergic, and serotonin are the known ones. Here, the common significant genes are examined to understand the possible molecular origin of the diso...
The major endocrine regulators of the female reproductive tract are 17β-estradiol (E2) and progesterone (P4). This review discusses our recent work related to the roles of E2 and P4 and their receptors, estrogen receptor 1 (ESR1) and progesterone receptor (PR), respectively, in the neonatal uterus. Neonatal uterine cells in mice are mitogenically responsive to estrogens, but neonatal ovariectom...
A cross talk between the Estrogen Receptor (ESR1) and the Retinoblastoma (pRb) pathway has been demonstrated to influence the therapeutic response of breast cancer patients but the full mechanism remains poorly understood. Here we show that the N-terminal domain of pRb interacts with the CD domain of ESR1 to allow for the assembly of intermediate complex chaperone proteins HSP90 and p23. We dem...
Figure S1. The quality control results of 48 clinical breast cancer gene expression arrays (48A) were derived by measuring the significance of linear associations between the relative quantitative mRNA levels of four chosen genes and their corresponding gene expression profiles in 48A. The values of correlation coefficient (R) for ESR1, PGR, ERBB2 and GPR30 are 0.9683, 0.9463, 0.9691 and 0.7267...
