[Abstract]  Organisms have developed many protective systems to reduce the toxicity from heavy metals. The nematode Caenorhabditis elegans has been widely used to determine the protective mechanisms against heavy metals. Responses against heavy metals can be monitored by expression of reporter genes, while sensitivity can be determined by quantifying growth or survival rate following exposure to heavy metals. [摘要]  生物开发了许多保护系统,以减少重金属的毒性。线虫秀丽隐杆线虫已广泛用于确定重金属的保护机制。可以通过报告基因的表达来监测对重金属的反应,而敏感性可以通过量化暴露于重金属后的生长或存活率来确定。

背景 一些重金属如砷,镉和汞已知对包括人类在内的大多数生物有害(Valko et al。,2005)。为了降低这些金属的毒性,生物开发出各种保护系统。线虫秀丽隐杆线虫已被用于了解重金属的保护机制。以前的研究表明,许多基因,如解毒酶,转录因子和信号传导因子都参与了该生物体中重金属的保护(Broeks et al。,1996; Mizuno et al。 ,2004; Inoue等人,2005; Schwartz等人,2010)。除了测量报告基因表达外,生存力和生长的测定通常用于监测重金属在C中的影响。线虫。在本协议中,我们描述了使用C测定砷,铜和镉的方法。线虫。
