HIF1A and ovarian carcinoma: Both the high transduction efficiency (Fig. S6A) and the increased mRNA (Fig. S6B) and protein expression (Fig. S6C) of HIF‐1α and HIF‐2α in HIF‐1A‐cDNA‐transduced and EPAS1‐cDNA‐transduced cells indicate that ovarian cancer cells successfully overexpressed either HIF‐1α or HIF‐2α.
