It declines with age and in various diseases, there is a need for a method to compensate for the decrease in coenzyme Q10. Resveratrol, a well-known anti-aging compound, has been shown to undergo metabolism to coenzyme Q10's benzene ring moiety in cells. However, administration of resveratrol did not alter or only slightly increased total intracellular coenzyme Q10 levels in many cell types. Synthesis of coenzyme Q10 requires not only the benzene ring moiety but also the side chain moiety. Biosynthesis of the side chain portion of coenzyme Q10 is mediated by the mevalonic acid pathway.

Bioinformatics analysis was used to determine the upstream regulatory factor of RECQL4 and CREB1. Their binding relationship was evaluated by dual luciferase and Chromatin Immunoprecipitation assays.

CREB1 knockdown promoted mitophagy and prevented the metastasis of cancer cells, which could be countered by overexpressing RECQL4.
