A set of isoflavononid and flavonoid analogs was prepared evaluated for estrogen receptor α (ERα) ERβ transactivation anti-neuroinflammatory activities. Structure–activity relationship (SAR) study naturally occurring phytoestrogens, their metabolites, related isoflavone revealed the importance C-ring isoflavonoids ER activity selectivity. Docking suggested putative binding modes daidzein 2 dehy...
Indole-3-carbinol (I3C), a naturally occurring hydrolysis product of glucobrassicin from cruciferous vegetables such as broccoli, cabbage and Brussels sprouts, is an anticancer phytochemical that triggers complementary sets of antiproliferative pathways to induce a cell cycle arrest of estrogen-responsive MCF7 breast cancer cells. I3C strongly downregulated transcript expression of the catalyti...
The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that mediates the effects of the environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Recently, AHR has emerged as a potential therapeutic target for breast cancer by virtue of its ability to modulate estrogen receptor-α (ERα) signalling and/or its ability to block cell proliferation. Our previous st...
Estrogens are important regulators of cardiovascular function. Some of estrogen's cardiovascular effects are mediated by a G-protein-coupled receptor mechanism, namely, G-protein-coupled estrogen receptor (GPER). Estradiol-mediated regulation of vascular cell programmed cell death reflects the balance of the opposing actions of GPER versus estrogen receptor α (ERα). However, the significance of...
Gene-specific promoter methylation of several genes occurs in aging normal tissues and may predispose to tumorigenesis. In the present study, we investigate the association of blood folate levels and dietary and lifestyle factors with CpG island (CGI) methylation in normal colorectal mucosa. Subjects were enrolled in a multicenter chemoprevention trial of aspirin or folic acid for the preventio...
سابقه و هدف: بیان ژنتیکی گیرنده استروژن-آلفا (α,ERα (Estrogen receptor-در سلول‌های تومور پستان اهمیت درمانی دارد و بیان این ژن می‌تواند به واسطه هیپرمتیلاسیون در اگزون 1 مهار شود. هدف از انجام این پژوهش، بررسی ارتباط بین مقادیر فولات، ویتامین B12 و هموسیستئین تام پلاسما با وضعیت هیپرمتیلاسیون ERα در مبتلایان به سرطان پستان برای اولین بار بود. مواد و روش‌ها: جامعه مورد بررسی 137بیمار مبتلا به س...
Endometriosis is an estrogen-dependent gynecologic disease, which characterized by the elevated ratio of ERβ/ERα expression. Retrograde menstruation leads to ectopic erythrocytes deposition and iron overload at pelvic cavity in endometriosis. Lipocalin 2 (LCN2) a secretory protein that plays important role during transport metabolism. To date, relationship estrogen homeostasis not well studied ...
We studied functional effect of rs12722489 single nucleotide polymorphism located in the first intron of human IL2RA gene on transcriptional regulation. This polymorphism is associated with multiple autoimmune conditions (rheumatoid arthritis, multiple sclerosis, Crohn's disease, and ulcerative colitis). Analysis in silico suggested significant difference in the affinity of estrogen receptor (E...
