...tion. Clomifene inhibits estrogen receptors in the hypothalamus, inhibiting negative feedback of estrogen on gonadotropin release and leading to up-regulation of ovulation. It has useful effects on the reproduction of female in terms of reduction in puberty and ovulation induction. The beneficial effects are manifested in male in terms of improvement of semen.

... used as a biomarker for estrogenic endocrine disruption. To elucidate the endocrine-disrupting effect of bisphenol-A, juvenile Catla catla was exposed to graded concentrations of bisphenol-A (10,100,1000μg/l) for 14 days. BPA exposure strongly elevates vtg mRNA level in fish exposed to 100μg/l but at 1000 μg/l exposure of BPA, vtg level decreased compared to 100µg/l exposed fish. These results showed that BPA has

...affect the production of estrogen. In the present study, to detect the effects of letrozole on gonad differentiation, 5dph fry of carp were exposed to different concentrations of LET. At 130 dph, sex ratio was recorded. The results showed that continuous exposure to LET induced the changes of sex ratio. High concentration of LET can promote male-biased sex ratio. In order to reveal the molecular mechanism by which LET caused sex reversal, juvenile carp (120dph...

...fy;">Endometriosis is an estrogen-regulated disease, and is signified by the existence of a particular endometrial tissue exterior to the uterus. It is a principal cause of long lasting morbidity, mostly from serious pelvic pain(1). Endometriotic tissue has the potential for aromatase gene expression that leads to aromatase and estrogen production. Danazol is a synthetic androgen whereas Letrozole is aromatase inhibitor. Thi...

The objective of our study was to examine the expression of HMG-CoAR in primary breast carcinomas and determine its association with ER/PR expression.
Material & Methods: Cross-sectional analytical study was conducted to examine the immunohistochemical expression of HMG-CoA...

...cancer due to absence of estrogen, progesterone and HER2 receptors. We aimed to identify a panel of circulating miRNAs which can act as diagnostic and prognostic biomarkers specifically for TNBC. The blood samples were collected from 37 TNBC diagnosed patients and 34 age-matched non-TNBC controls to investigate the expression of miRNA panel. Plasma was isolated by standard protocol of centrifugation and then isolation of total RNA including miRNA was done. Abo...

AGR2 exists in both intracellular and secreted form, it is overexpressed in many types of cancer cells and also detected in extracellular space of solid tumor interstitial fluids. The intracellular AGR2 is critical in protein folding while secreted AGR2 function as a paracrine signal ...

PCR products were used to directly sequence the polymorphism of exon 4 of ESR gene in three quail populations (Chinese yellow quail, Korean quail, Beijing white quail) and analyze the association between ESR gene and growth traits of quails. The results show that three genotypes, CC, CT and TT, were detected in exon 4 of ESR1 gene in t...

The results showed that three genotypes, CC, CT and TT, were detected in exon 1, exon 4 and exon 8 of ESR gene. The frequencies of CC genotype in expressed exon 1 of ESR gene were the highest in french giant quail and savimit quail (0.531 and 0.778, respectively). The frequencies of TT genotype in expressed exon 4 of ESR...

All rabbits were randomly divided into two treatment groups, namely control group (K1) and treatment group (K2) where each group consist of five rabbits. The rabbits of K1 group were injected with aquabides for three consecutive days at a doses of 1.0, 0.5 and 0.3 mL each, whereas rabbits K2...

The aim of this approach is to lower the population size of pests by reducing the natality rather than by increasing mortality. Male (20) and female (40) albino mice were orally administered testosterone at 25 mg/kg for 35 days. The males were allowed to mate with females to estimate the fertility index. After the end of treatment, mice were sacrificed, b...

Highest level of E2 was recorded in pregnant cows in POP group in comparison with MSS. The P4 concentration of pregnant cows in MSS was lowest at the time of insemination (P<0.05). Induction of fertile estrous was maximum in POP group than MSS, but conception rate in cows recei...
