Chemerin (CHEM) is a hormone mainly expressed in adipocytes involved in the regulation of energy homeostasis and inflammatory response. CHEM expression has been demonstrated in the structures of the porcine hypothalamic-pituitary-gonadal axis, as well as in the uterus, trophoblasts and conceptuses of pigs. In this study, we performed high-throughput proteomic analyses (liquid chromatography with tandem mass spectrometry, LC-MS/MS) to examine the influence of CHEM (400 ng/mL) on differentially regulated proteins (DRPs) in the porcine endometrial tissue explants during implantation (15 to 16 days of gestation).

It is well known that the body's metabolism and reproduction are closely related. Chemerin (CHEM) is one of many biologically active proteins secreted by the adipose tissue involved in the regulation of the energy homeostasis of the organism. In the present study, RNA-sequencing was performed to investigate the differentially expressed genes (DEGs), long non-coding RNAs (lncRNAs), and alternatively spliced (AS) transcripts in the cultured porcine endometrium exposed to chemerin for 24 hours (CHEM; 400 ng/mL) collected during the implantation period (15-16 days of gestation).

In this study, aims were to evaluate orexin A (OXA) effects on mRNA abundance of important enzymes involved in prostaglandin production, such as cyclooxygenase 2 (PTGS2), microsomal PGE synthase-1 (PTGES), PGF synthase (PGFS) and carbonyl reductase 1 (CBR1), as well as prostaglandin E (PGE) and F (PGF) culture medium concentrations for endometrial and myometrial explants. Tissues were collected from gilts during specific phases of the estrogenic cycle or early gestational period. There were greater concentrations of PGE with OXA treatments of endometrial tissues collected on days 12-13 and 27-28, as well as PGF on days 10-11 of the gestational period.
