Overexpression of KLF2 expression inhibits HepG2 cell proliferation and improves apoptosis. (A) The mRNA level of KLF2 in HepG2 and Hep3B cells transfected with pCMV-Tag2B-KLF2 or empty vector was detected by qPCR. (B,C) MTT assays and colony formation assays were used to determine the cell viability for pCMV-Tag2B-KLF2-transfected or empty vector-transfected HepG2 and Hep3B cells. Values represent the mean ± s.d. from three independent experiments. (D) Apoptosis was determined by flow cytometry. UL, necrotic cells; UR, terminal apoptotic cells; LR, early apoptotic cells. *P < 0.05 and **P < 0.01.
