Comparisons of gene expression from microarray and qRT-PCR analysis. Empty bars represent the Log2 ratio obtained from microarray analysis and filled bars represent this value obtained by qRT-PCR. †: P < 0.10; *: P < 0.05; **P < 0.01; ***P < 0.001. a Log2 ratios obtained by comparing chickens thermally manipulated during embryogenesis and reared in standard conditions (TM) to control chickens incubated and reared in standard conditions (C). b Log2 ratios obtained by comparing control chickens submitted to a heat challenge at day 34 (CHC) to C chickens. c Log2 ratios obtained by comparing TM chickens submitted to a heat challenge at day 34 (TMHC) to TM chickens.
