Styrene altered clock gene expression in serum-shocked cultured human fibroblasts

Biosci Biotechnol Biochem. 2013;77(6):1296-8. doi: 10.1271/bbb.120944. Epub 2013 Jun 7.

Abstract

The circadian clock can regulate the metabolic process of xenobiotics, but little is known as to circadian rhythms can be perturbed by xenobiotics. Styrene is a organic chemical widely used in occupational settings. The effects of styrene on the circadian genes of HuDE cells were evaluated after serum-shocking synchronization. A subtoxic dose of 100 µM of styrene altered the expression of clock genes BMAL1, PER2, PER3, CRY1, CRY2, and REV-ERB-α.
