Fig. 7From: Long-term effect of early postnatal overnutrition on insulin resistance and serum fatty acid profiles in male ratsmRNA expression of key insulin signaling components in the gastrocnemius muscle at 16 weeks. mRNA levels of Irs-1, Akt2 and Glut4 were assessed by quantitative PCR in the gastrocnemius of rats from normal litters (NL, open bars) and small litters (SL, closed bars). Results are expressed as mean ± S.E.M (n = 6, 4 litters from each group). * P < 0.05, ** P < 0.01Back to article page
