Figure 1. ITPKA inhibited colony formation and induced cell senescence in ovarian cancer. (A) Overexpression of ITPKA in OVCAR3 and OVCA429 cells. Cells were transfected with pLVX plasmids or pLVX-Flag-ITPKA plasmids. After selection, the resistant cells were examined for the expression of Flag-tagged ITPKA. (B) Effects of ITPKA on the colony formation of OVCAR3 and OVCA429 cells were examined using a soft agar assay. (C) Statistical analysis of (B). (D) Effects of ITPKA on the senescence of OVCAR3 and OVCA429 cells were examined using β-gal staining. (E) Statistical analysis of (D). **P < 0.01.
