Hsp70 expression of P. chinensis, Sp. indicus and Sc. modesta in response to different temperature in short time. Hsp70 expression in liver was determined by quantitative real time reverse transcriptase PCR at various times post-exposure. The mRNA level of Hsp70 was normalized to that of β-actin mRNA. Values are shown as means ± SE (n = 5). Significances between room temperature lizards and heat post-exposure lizards are indicated with asterisks. *P < 0.05.
