متن کاملPRAP, a prolactin receptor associated protein: its gene expression and regulation in the corpus luteum.
We have recently identified, characterized, and cloned a luteal microsomal 32-kDa phosphoprotein that we named PRAP (for PRL-receptor associated protein), and we have demonstrated that PRAP binds to the intracellular domain of the short but not the long form of the PRL receptor. In this study, we used PRAP cDNA to examine the tissue specificity, the developmental expression, and the hormonal re...
متن کاملEarly transcriptome responses of the bovine midcycle corpus luteum to prostaglandin F2α includes cytokine signaling.
In ruminants, prostaglandin F2alpha (PGF2α)-mediated luteolysis is essential prior to estrous cycle resumption, and is a target for improving fertility. To deduce early PGF2α-provoked changes in the corpus luteum a short time-course (0.5-4 h) was performed on cows at midcycle. A microarray-determined transcriptome was established and examined by bioinformatic pathway analysis. Classic PGF2α eff...
متن کاملThe expression of prolactin and its cathepsin D-mediated cleavage in the bovine corpus luteum vary with the estrous cycle.
In the corpus luteum (CL), blood vessels develop, stabilize, and regress. This process depends on the ratio of pro- and antiangiogenic factors, which change during the ovarian cycle. The present study focuses on the possible roles of 23,000 (23K) prolactin (PRL) in the bovine CL and its antiangiogenic NH(2)-terminal fragments after extracellular cleavage by cathepsin D (Cath D). PRL RNA and pro...
متن کاملExpression of leptin and leptin receptor transcript in ovine corpus luteum
Background: Leptin, the product of the obesity (ob) gene, acts as a signaling adipokine for modulating food intake, energy metabolism and reproductive functions in mammals. Leptin’s effects on the reproductive system at various levels of the hypothalamic-pituitary-gonadal axis have been established. Moreover, the direct and local effect of leptin on bovine oocyte maturation and corpus luteum fu...
