Several different in vitro binding assays show that the estrogen receptor from rabbit uterus interacts selectively with purified histones from calf thymus. The estrogen receptor binds strongly to histones H2B and H2A, moderately to histones H3 and H4, and poorly to histone H1. In the presence of histones H2B or H2A, the position at which the estrogen receptor focuses in an isoelectric gradient ...
Recent studies have revealed that hundreds of genes in the uterus are activated by estrogen. Their expression profiles differ over time and doses and it is not clear whether all these genes are directly regulated by estrogen via the estrogen receptor. To select the genes that may be regulated by estrogen, we treated mice with several doses of estrogen and searched for those genes whose dose-res...
We have previously shown that neurons in the basal forebrain colocalize the neurotrophin receptor p75NGFR and estrogen receptors. The present study was designed to examine (1) if neural neurotrophin targets respond to estrogen as a general phenotypic feature and (2) if NGF receptor mRNAs are regulated by estrogen, using a prototypical target of NGF, the dorsal root ganglion (DRG) (sensory) neur...
We studied the effect of ovariectomy and estrogen replacement on expression of adrenal angiotensin II AT1 and AT2 receptors, aldosterone content, catecholamine synthesis, and the transcription factor Fos-related antigen 2 (Fra-2). Ovariectomy increased AT1 receptor expression in the adrenal zona glomerulosa and medulla, and decreased adrenomedullary catecholamine content and Fra-2 expression wh...
Breast cancer death polls are rising at an alarming rate in females globally. It is a hormone-dependent disease that majorly regulated by estrogen. Several genetic and environmental factors the primary attributes of breast growth development. A higher proportion patients harbor estrogen receptor-positive (ER+ve) status. Estrogen related receptors orphan nuclear which include ERRα, ERRβ, ERRϒ ex...
Lipid metabolism disorders commonly occur during menopause. Estrogen deficiency has been shown to lead excessive energy intake and abnormal lipid in ovariectomized rats, resulting obesity. Probiotics exhibit anti-obesity properties, their underlying mechanism widely reported. In this study, we demonstrated the metabolic benefits of Lactobacillus plantarum CCFM1180 suppressing appetite, c...
background: systematic treatments such as hormone and chemotherapy are selected according to tumor characteristic after major therapeutic approaches such as surgery. this study attempted to analyze and compare the status of estrogen receptor (er) and progesterone receptor (pr) in primary and recurrent sites of breast cancer in patients. methods: we reviewed all medical records of breast cancer ...
This short-term study of the relative importance of estrogen and progesterone receptors shows that progesterone receptor correlates better than estrogen receptor with tumor recurrence regardless of lymph-node status. Life-table analysis has effectively identified only two groups of patients that may be classified by progesterone receptor status alone. Progesterone-receptor negativity correlated...
Breast cancer is the most common malignancy in women and hormone resistance is a challenging problem in its treatment. Loss of estrogen receptor expression is an important means of hormone resistance, but the mechanisms involved are poorly understood. We now demonstrate a potential role for abnormal DNA methylation in transcriptional inactivation of the estrogen receptor gene. Estrogen receptor...
