CRY1, BMAL1, PER1, PPARGC1A, and CLOCK are key circadian clock genes that govern the daily rhythms of diverse physiological processes in mammals. These genes create a feedback loop called a transcriptional-translational feedback loop (TTFL). In this loop, the heterodimer of CLOCK and BMAL1 stimulates the production of CRY1, PER1, and other clock genes. Moreover, the CRY1 and PER1 proteins suppressed the activity of CLOCK-BMAL1. PPARGC1A is a transcription factor that regulates the expression of clock genes and metabolic genes. Only a limited number of agonists are currently known to activate these genes. In this study, we showed that treatment with metadichol, a nanoemulsion of long-chain alcohols, significantly increased the expression of the CRY1, CLOCK, and PPARGC1A genes by 4-5-fold in human fibroblasts. Additionally, 100 ng of metadichol maintained the expression of the PER1 and BMAL1 genes, as confirmed by quantitative real-time polymerase chain reaction (Q-rt-PCR) data. The lack of significant changes in PER1 and BMAL1 expression suggested that metadichol does not directly affect these genes. However, since these genes are part of the core circadian clock machinery, their normal functioning is crucial for maintaining the circadian rhythm.Read More
