Hepatic mRNA expression of Caspase 3 (A), Caspase 9 (B), Smac/DIABLO (C), Apaf-1 (D), Noxa (E), Caspase 8 (F), Bcl-2 (G), Bax (H), and p53 (I) in male and female of wild-type (WT) and liver-specific growth hormone receptor knockout (LiGHRKO) mice. The data from real-time PCR were normalized by the housekeeping gene β2-Microglobulin (B2M) and expressed as the relative expression. Values are means ± SEM. (a) Values that share the same letter in the superscript are not statistically significant.
