Melatonin and ethanol intake exert opposite effects on circulating estradiol and progesterone and differentially regulate sex steroid receptors in the ovaries, oviducts, and uteri of adult rats
(2013-08-01)
Chronic ethanol intake is associated with sex hormone disturbances, and it is well known that melatonin plays a key role in regulating several reproductive processes. We report the effects of ethanol intake and melatonin ...
Evaluation of estrogen receptor alpha and beta and progesterone receptor expression and correlation with clinicopathologic factors and proliferative marker Ki-67 in breast cancers
(W B Saunders Co-elsevier Inc, 2008-05-01)
To elucidate the molecular profile of hormonal steroid receptor status, we analyzed ER-alpha, ER-beta, and PGR mRNA and protein expression in 80 breast carcinomas using reverse transcriptase polymerase chain reaction ...

Differential expression of aromatase, estrogen receptor alpha and 17 beta-HSD associated with the processes of total testicular regression and recrudescence in the bat Myotis nigricans (Chiroptera: Vespertilionidae)
(Elsevier B.V., 2014-05-15)
Despite the worldwide distribution and many unique reproductive adaptations that bats present, many aspects of their reproductive hormonal regulation have not been adequately studied, especially in species that presented ...
Profiling of gene expression regulated by 17 beta-estradiol and tamoxifen in estrogen receptor-positive and estrogen receptor-negative human breast cancer cell lines
One area of great importance in breast cancer (BC) research is the study of gene expression regulated by both estrogenic and antiestrogenic agents. Although many studies have been performed in this area, most of them have ...
Estrogen receptors mediate rapid activation of phospholipase C pathway in the rat endometrium
(Elsevier B.V., 2011-12-20)
The aim of the present study was to investigate the activation of rapid signaling events by 17 beta-estradiol in the rat uterus. 17 beta-Estradiol induced a rapid increase of total [(3)H]-inositol phosphate accumulation ...
