热应激对大鼠肝脏节律性基因Per2mRNA表达水平的影响
Effects of heat stress on Per2 mRNA expression in the liver of rats
摘要
Abstract
Objective To investigate the effect of acute heat stress on the day-night arcadian gene Perl mRNA expression in the liver of rats. Method Male Wistar rats were randomly divided into two groups and exposed to heat at 32 ℃ or to a room temperature at 24 ℃ (control). After 7 days of heat exposure, the body temperature was measured by telemetry. The relative weight of the pituitary and adrenal glands was determined after the exposure, and liver Perl mRNA expression level was detected using RT-PCR. Results Acute heat stress did not obviously affect body temperature or body weight of the rats. Seven days of heat exposure increased the relative weight of the pituitary and adrenal glands and significantly lowered Perl mRNA expression level at night. Conclusion Acute heat stress can interfere with the day-night circadian gene Perl mRNA expression in rats.关键词
