摘要: 铬是一种人体的必需微量元素,其存在的价态与其对人体的效用存在密切联系。三价铬是铬在自然界中最稳定的化合态,可作为胰岛素的协助因子参与调控体内糖、脂肪和蛋白质的代谢,对人体没有表观遗传毒性。而六价铬为致癌物,可通过干扰DNA 甲基化、组蛋白修饰、染色体重塑和非编码RNA 调控等表观遗传模式对人体健康造成严重威胁。综述对充分认识三价铬的生物学功能和六价铬的表观遗传毒性有重要的意义。

Abstract: Chromium is an essential trace element in human body, and its ion valence state is closely related to its effect on human body. Trivalent chromium is the most stable state of chromium in nature. It can be used as a co-factor of insulin to regulate the metabolism of sugar, fat and protein, and has no epigenetic toxicity to human body. Howerver, hexavalent chromium, a carcinogen, poses a serious threat to human health by interfering with epigenetic patterns such as DNA methylation, histone modification, chromosomal remodeling and non-coding RNA regulation. This review is of great significance to fully understand the biological functions of trivalent chromium and the epigenetic toxicity of hexavalent chromium.

Key words: chromium, trace element, insulin, epigenetic
