在不利环境中，各种有机体都有共同的分子反应，即正常基因的表达抑制和一组特殊基因─－热休克基因的激活和表达，并产生热休克蛋白作为＂分子伴娘＂而参与蛋白质的折叠、转运、转位及生物合成等过程，使细胞产生热耐受。热休克基因的表达受转录和转录后双重调节，在高等动物还要受神经、内分泌的影响，此外也受年龄因素的影响。 In unfavorable environment, all kinds of organisms have a common molecular response, that is, the inhibition of expression of normal genes and the activation and expression of a group of special genes ─ ─ heat shock genes and the production of heat shock protein as a “molecular bridesmaid” involved in the protein Folding, transport, translocation and biosynthesis process, the cells produce heat tolerance. Heat shock gene expression by transcription and transcription after the double regulation, but also in higher animals by the nervous, endocrine effects, in addition also affected by age factors.
