TGFβ1 mRNA expression (A and B) and protein concentration (C and D) in the endometrium of gilts subjected to surgical procedure. Gilts were slaughtered on days 11 or 14 of the estrous cycle and early pregnancy. Values from real-time PCR were normalized to GAPDH. Data are expressed as means ± SEM (n=4–5). Letters above bars (capital letters for connected uterine horn and small letters for detached uterine horn) indicate differences between cyclic and pregnant gilts. Asterisks indicate differences between the connected and detached uterine horn in cyclic and pregnant gilts (*, P<0.05; **, P<0.01).
