RNA levels were determined by qPCR analysis of individual livers from wild-type (WT) male (n=6) and female (n=5) mice and STAT5b-deficient (KO) male (n=6) and female (n=7) mice. Data were analyzed as described in Fig. 6, with the wild-type male RNA level set to 1.0 for each gene, and graphed as mean ± SE for each group. Data were analyzed using Student’s t-test: + and ++, p<0.05 and p<0.01, respectively, for STAT5b-deficient male (or female) vs. wild-type male (or female); * and **, p<0.05 and p<0.01, respectively, for wild-type (or STAT5b-deficient) female vs. wild-type (or STAT5b-deficient) male.
