Abstract

The objective of this study was to determine the expression profiles of leukemia inhibitory factor (LIF) and its receptor (LIFR), interleukin 6 receptor (IL6R), tumor protein p53 (TP53) and B-cell CLL/lymphoma 2 (BCL2) in the porcine endometrium on selected days of the estrous cycle and pregnancy. Time- and reproductive status (estrous cycle/pregnancy)-specific patterns of expression were identified for all investigated genes. The most pronounced changes were seen on Days 12 and 14 of pregnancy when maternal recognition of pregnancy and implantation, respectively, occurs in pigs.

Keywords: BCL2; IL6R; LIF; LIFR; Pig; TP53.
