摘要: 背景与目的: 研究微囊藻毒素LR(microcystin LR,MCLR)对正常人羊膜细胞FL和肝实质细胞HL7702蛋白磷酸酶2A(PP2A)各亚基mRNA表达的影响。材料与方法: FL和HL7702经100 nmol/L MCLR作用24 h后,采用实时定量PCR方法检测PP2A各亚基mRNA表达的变化。实验并设溶剂对照组。 结果: FL细胞PP2A各亚基mRNA表达部分上升,部分下降;而HL7702细胞PP2A各亚基mRNA表达均上升。 结论: MCLR对肝来源细胞的特异性作用可能与其肝脏毒性有关。

Abstract: BACKGROUND AND AIM: To investigate the effects of microcystin LR on the mRNA expression of protein phosphotase 2A subunits of human amniotic (FL) cells and human hepatocyte HL7702 cells. MATERIALS AND METHODS: After treated with 100 nmol/L MCLR for 24 h, the mRNA expression of protein phosphotase 2A subunits of human amniotic cells and human hepatocyte cells was measured by real time PCR. RESULTS: The changes of subunits expression were diverse in human amniotic cells but increased significantly in human hepatocyte cells. CONCLUSION: The special effects of MCLR on HL7702 cells could be account for its hepatotoxicity.

Key words: protein phosphotase 2A, microcystin LR, mRNA, real time PCR
