Afterward, we observed that the expression of ZNF252P-AS1 was distinctly increased in SKOV3, A2780, HO8910 and OVCAR3 ovarian cancer cells compared to IOSE80 normal ovarian cells, and the expression level was highest in SKOV3 and A2780 cells (Fig. 1D). This evidence concerns the gene ZNF252P and ovarian cancer.
