摘要：
Circadian rhythm pervades in many aspects of the biological processes including basic cellular functions. Here we examined the circadian gene expression of two forms of 90 kDa heat shock proteins referred to HSP86 and HSP84 in the mouse suprachiasmatic nucleus, the circadian center. In both light-dark, and constant dark conditions, Hsp86 mRNA showed an overt circadian rhythm showing a peak at (subjective) night and a trough at (subjective) day. Hsp84 mRNA also showed the similar expression profile, but the amplitude was weaker. These results indicate that gene expression of molecular chaperone such as Hsp86 and Hsp84 are regulated by the circadian clock.
