Methods RTqPCRmethod was used to detect the expression and correlationof CMTM5,caspase3 and caspase9 in U266 afterdecitabine demethylation treatment;U266 transfectedwith pcDNA3. 1 plasmid overexpressed CMTM5,then cell proliferation activity was detected by CCK-8 assay.Results Compared with the control group,the low-dosedemethylation treatment increased mRNA expression ofCMTM5,caspase3,and caspase9 in U266,and showeda time-dependent (P < 0. 01). The up-trend of CMTM5,caspase3,and caspase9 in the high-demethylation drugtreatment group was more significant and also showed atime-dependent manner (P < 0. 001);There was a significantpositive correlation between CMTM5 andcaspase3 (r = 0. 937) and caspase 9 ( r = 0. 945) ineach group (P < 0. 001). After transfection of U266 withthe pcDNA3. 1-CMTM5 plasmid,overexpression of CMTM5inhibited the cell proliferation activity compared with thecontrol and the pcDNA3. 1-vector group.展开更多
