Expression profile of mRNAs encoding core circadian regulatory proteins in human subcutaneous adipose tissue: correlation with age and body mass index

摘要

Objective:Circadian mechanisms underlie the physiology of mammals as an adaptation to the earth's rotation on its axis. Highly conserved core circadian regulatory proteins (CCRPs) maintain an oscillatory expression profile in the central and peripheral tissues. The CCRP include both a positive and negative arm, as well as downstream transcriptional regulators. Recent studies in murine models have determined that the mRNAs encoding the CCRP are present in multiple adipose tissue depots and exhibit a robust oscillatory expression profile. This study set out to examine the expression of CCRP mRNAs in human subcutaneous adipose tissues.
