目的：Ｃｆｏｓ遗传因子是在肾近曲小管由于缺血和重金属及化学物质接触后发现的。本文作者探讨在猪近曲小管上皮细胞的ＬＬＣＰＫ１细胞（屈普二氏细胞），氯化汞对Ｃｆｏｓ遗传因子表达的影响。方法：把ＬＬＣＰＫ１细胞在无血清的情况下，使之接触２０μｍＨｇＣｌ Objective: C  fos genetic factors in the proximal renal tubule due to ischemia and heavy metals and chemical substances found after contact. The authors explore the pig proximal tubule epithelial cells of LLC PK1 (Quaker cells), mercuric chloride on C  fos genetic factor expression. METHODS: LLC-PK1 cells were exposed to 20 μm HgCl without serum
