Endometrial transcript profile of progesterone-regulated genes during early pregnancy of Water Buffalo (Bubalus bubalis).

Progesterone (P ) plays a key role in the establishment and maintenance of pregnancy in most mammals. Unravelling the expression of progesterone-regulated genes can expand the understanding of the embryonic mortality. Accordingly, we studied the relative mRNA expression of the P -regulated genes in the buffalo.

Differential expression of ten candidate genes regulating prostaglandin action in reproductive tissues of buffalo during estrous cycle and pregnancy.

Prostaglandins (PGs) are the key mediators of several female reproductive functions, including luteolysis, ovulation, fertilization, implantation, pregnancy, and parturition. The present study was conducted in buffalo endometrial and luteal tissues between nonpregnant and two stages of pregnancy (29-38 days of pregnancy, 48-56 days of pregnancy) tissue samples. The genes involved from synthesis upto receptor level effect of PGs (PGF and PGE) were studied for their relative mRNA expression.

Study of lysophosphatidic acid receptors (LPARs) in buffalo uterus demonstrated upregulation of LPAR1 and LPAR6 in early pregnancy.

Lysophosphatidic acid (LPA) is an important factor involved in embryo implantation and pregnancy establishment in humans and domestic livestock. LPA exerts its action through six G-protein-coupled receptors (LPA1-LPA6). We investigated the types of LPA receptors expressed in buffalo uterus and also their differential expression in the nonpregnant, and early-pregnant endometrium.

Hypercholesterolemia impairs oxytocin-induced uterine contractility in late pregnant mouse.

High cholesterol is known to negatively affect uterine contractility in conditions. The aim of the present study was to reveal the effect of hypercholesterolemia on spontaneous and oxytocin-induced uterine contractility in late pregnant mouse uterus. Female Swiss albino mice were fed with high cholesterol (HC) diet (0.
