qPCR analysis of the expression of genes involved in growth.

<p>Panel A – qRT-PCR analysis of key genes involved in the control of growth, [Insulin-like Growth Factor (IGF-1), its receptor (IGF-1R) and growth hormone receptor (GHR)] in pectoralis muscle from 1, 7, 15, 30 and 60 –day- old Adélie chicks. The relative expression of each gene was expressed as a ratio to the β-actin mRNA level. Panel B - Protein abundance of growth hormone receptor (GHR) from the same chicks. N = 6 per group. Bars correspond to means ± S.E.M. values. Bars with different letters are significantly different at p<0.05.
