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.
昼夜节律时钟可以调节外源性物质的代谢过程，但关于外源性物质是否会扰乱昼夜节律却知之甚少。苯乙烯是一种在职业环境中广泛使用的有机化学品。血清休克同步化后，评估了苯乙烯对人真皮成纤维细胞（HuDE细胞）昼夜节律基因的影响。100μM的亚毒性剂量苯乙烯改变了生物钟基因BMAL1、PER2、PER3、CRY1、CRY2和REV-ERB-α的表达。
