Nearly one in eight US women will develop breast cancer in their lifetime. Most breast cancer is not associated with a hereditary syndrome, occurs in postmenopausal women, and is estrogen and progesterone receptor-positive. Estrogen exposure is an epidemiologic risk factor for breast cancer and estrogen is a potent mammary mitogen. We studied single nucleotide polymorphisms (SNPs) in estrogen r...
BACKGROUND The present study was undertaken to find out the role of estrogen pathway related gene polymorphisms in susceptibility to migraine in Northern Indian population. Aromatase, CYP19A1 (rs10046 and rs4646); estrogen receptors, ESR1 (rs2234693, rs1801132, rs2228480 and rs9340799) and ESR2 (rs1271572 and rs1256049) polymorphisms were selected for the present study. METHODOLOGY/PRINCIPAL ...
Objective The estrogen receptor (ER) and the human epidermal growth factor receptor 2 (HER2) each play an important role in female cancers. This study aimed to investigate the genetic association between three common single nucleotide polymorphisms (SNPs) and the risk of ovarian cancer. The SNPs investigated in this study were ESR2 rs1271572 and rs3020450 and HER2 rs1801200. Methods In this s...
The aim of the study was to evaluate the correlation of c-erb-b2 and Bcl-xl expression in biopsy specimens of Barrett's oesophagus from 44 patients with morphological features. The examined group was subdivided into: negative for dysplasia, indefinite for dysplasia, positive for dysplasia-low grade, and adenocarcinoma with high grade dysplasia. Positive c-erb-B2 staining was found in 34.1% and ...
INTRODUCTION Obtaining an adequate number of high-quality oocytes is a major challenge in controlled ovarian hyperstimulation (COH). To date, a range of hormonal and clinical parameters have been used to optimize COH but none have significant predictive value. This variability could be due to the genetic predispositions of single-nucleotide polymorphisms (SNPs). Here, we assessed the individual...
OBJECTIVE To correlate circulating hormone levels with the clinical and biological features of the tumors in menopausal breast cancer patients. DESIGN Circulating hormone levels were measured in 161 previously untreated menopausal breast cancer patients within 72 h of their planned surgery. The obtained hormone levels were correlated with tumor size, histological and nuclear grade, histologic...
In the present study, the efficacy of indole-3-carbinol (I3C), a key bioactive component of cruciferous vegetables, for prevention of cancer in offspring exposed in utero to the environmental carcinogen dibenzo[def,p]chrysene (DBC) was evaluated using an estrogen receptor β (ERβ) knockout mouse model. I3C was provided either through the maternal diet coincident with carcinogen exposure during p...
Bisphenol A (BPA) exposure is ubiquitous, and in laboratory animals, early-life BPA exposure has been shown to alter sex-specific neural organization, neuroendocrine physiology, and behavior. The specific mechanisms underlying these brain-related outcomes, however, remain largely unknown, constraining the capacity to ascertain the potential human relevance of neural effects observed in animal m...
