摘要:
摘要目的：探讨心肌细胞JP2与SK2通道的相互作用。方法：构建靶向小鼠JP2基因的siRNA慢病毒载体(LVJP2RNAi1、LVJP2RNAi2)，将其转染至小鼠心肌细胞，以转染空载体（LVNCEGFP）和未转染细胞（CtrlNC）作对照。采用实时荧光定量PCR和Western blot法分别检测各组心肌细胞JP2 mRNA和SK2蛋白的表达。结果：转染48 h后，各组小鼠心肌细胞JP2 mRNA表达的差异有统计学意义（F=31.775，P<0.001），LVJP2RNAi1、LVJP2RNAi2组较CtrlNC及LVNCEGFP组细胞降低。小鼠心肌细胞感染LVJP2RNAi2 72 h后，SK2通道蛋白表达被抑制。结论：沉默小鼠心肌细胞JP2基因可抑制SK2通道的功能。
Abstract:
AbstractAim: To investigate the relationship between JP2 and SK2 in the cardiomyocyte．Methods: The recombinants of lentiviral vectors targeting JP2 gene were constructed(LVJP2RNAi1,LVJP2RNAi2) for siRNA. The neonatal mouse cardiac myocytes(NMCMs) were infected with the recombinants. The levels of JP2 mRNA and SK2 protein were detected by quantitative realtime PCR and Western blot. Results: The JP2 mRNA level of the NMCMs among the four groups were different（F=31.775，P<0.001），which were significantly decreased in LVJP2RNAi1,LVJP2RNAi2 groups compared with control and LVNCEGFP groups. Compared with control and LVNCEGFP groups, the expression of the SK2 channel protein in the NMCMs with 72 h infection LVJP2RNAi2 was obviously inhibited. Conclusion: Knockdown of JP2 in the mouse cardiomyocyte could suppress the function of SK2 channel.
