The proximal region of the oviduct (isthmus) serves as a sperm reservoir in many mammalian species. This reservoir is composed of epithelial cells that bind sperm primarily to their apical cilia and ensure the survival of high-quality sperm until ovulation. The species-specific molecular interaction...

The purpose of this study was to identify molecular alterations potentially involved in predisposition to adnexal serous carcinoma (SerCa) in the non-malignant fallopian tube epithelium (FTE) of BRCA1/2-mutation carriers, given recent evidence implicating the distal FTE as a common source for SerC...

Mutations in BRCA1 and BRCA2 genes confer an increased lifetime risk for breast and ovarian cancer. Ovarian cancer risk can be decreased by risk-reducing salpingo-oophorectomy (RRSO). Studies on RRSO material have altered the paradigm of serous ovarian cancer pathogenesis. The purpose of this study ...

Estrogen receptor α (ERα) is a nuclear transcription factor crucial for the female reproductive function. We previously reported that mice lacking epithelial ERα in the epithelial cells of female reproductive tract (Wnt7aCre+;Esr1fl/fl, conditional knockout or cKO) were infertile, in part, due to...

Purpose: evaluate if different proestrus-estrus concentrations of estradiol (E2) and metestrus progesterone (P4) concentrations specifically regulate oviductal gene expression. Methods: ampulla and isthmus samples of animals with a large pre-ovulatory follicle and a large CL (LF/LCL) and animals wit...

Purpose: evaluate if different proestrus-estrus concentrations of estradiol (E2) and metestrus progesterone (P4) concentrations specifically regulate oviductal gene expression. Methods: ampulla and isthmus samples of animals whit a large pre-ovulatory follicle and a large CL (LF/LCL) and animals whi...

Effect of lactation and location relative to the corpus luteum on the transcriptome of the bovine oviduct epithelium
Lactation and associated metabolic stresses during the post-partum period have been shown to impair fertility in dairy cows. The oviduct plays key roles in embryo development and the establishment of pregnancy in cattle. The aim of this study was to investigate the effects of lactation and location ...
