The results revealed that IFI30 knockdown in KYSE150 and KYSE450 cells increased levels of Bax, Cytc, caspase‐7, cleaved caspase‐7, and cleaved caspase‐3, while decreasing Bcl‐2 levels (Figure 5c), indicating that IFI30 knockdown promotes apoptosis in ESCC cells. The gene discussed is BAX; the disease is esophageal squamous cell carcinoma.
