qPCR analysis of candidate genes in the endometrium significantly affected by progesterone. A-H Average calibrated, normalized, relative expression values (CNRQ ± SEM) as determined by qPCR in the endometrium of heifers with high (black bars), normal (white bars) and low (gray bars) circulating concentrations of P4 on either Day 7 or Day 13 of the estrous cycle. Significant differences (P<0.05) in gene expression values between treatments on a given day are identified with a, b, or c.
