The association between VDAC2 and methylation.
(A) Demethylation increases the expression of VDAC2. GC 2-spd cells were treated with 5, 10 and 15 μmol/L 5-Aza-CdR for 48 h. The expression of VDAC2 with 15 μmol/L dose 5-Aza-CdR was higher by threefold than that in the comparison group. (B) Strong promoter activity was detected by dual-luciferase reporter assay in the prognostic region −2000 bp to +1000 bp of VDAC2.
