Effects of adenovirus vector mediated Cx43 gene modification on GJIC function of acute leukemia bone marrow stromal cells / 第三军医大学学报

ABSTRACT

Objective To investigate the gene expression of connexin43(Cx43) and its effect on gap junction intercellular communication(GJIC) of acute leukemia bone marrow stromal cells(ALBMSCs).Methods After ALBMSCs were transfected by recombinant adenovirus Ad-Cx43-GFP,the expression of report gene GFP and the transfection efficiency were monitored by fluorescent microscopy.RT-PCR,Western blot and immunocytochemical method were used to detect the mRNA and protein expressions of Cx43.Dye transfer procedure was performed to examine the GJIC function.Results After transfected by Ad-Cx43-GFP for 24 h,the expression of GFP in ALBMSCs was detected by fluorescent microscopy and the transfection efficiency was(82.7?2.16)%;The mRNA and protein expressions of Cx43 in ALBMSCs transfected by Ad-Cx43-GFP were higher than those not transfected by Ad-Cx43-GFP(P
