Alterations in expression of endometrial genes coding for proteins secreted into the uterine lumen during conceptus elongation in cattle.

ABSTRACT:

Background

We hypothesized that genes that are up-regulated in the uterine endometrium at the initiation of conceptus elongation in cattle, and that encode for secreted proteins, contribute to the composition of the uterine luminal fluid (ULF) and ultimately, drive conceptus elongation. The aims of this study were to: 1) screen endometrial transcriptomic data for genes that encode secreted proteins on Day 13; 2) determine temporal changes in the expression of these genes during the estrous cycle/early pregnancy; 3) determine if expression of these genes is affected by altered concentrations of progesterone (P4) in vivo and 4) determine if the protein products of these genes are detectable in ULF.

Results

Of the fourteen candidate genes examined, quantitative real-time PCR an
