BECN1 and neoplasm: Furthermore, we constructed an in vivo tumor model by injecting SGC‐7901 cells into nude mice and found that the tumor growth was significantly inhibited in the BIX + Cis treatment group compared with others (Figures 4f and 4h), however, the deficiency of Beclin‐1 but not GSDME completely blocked the effect of BIX + Cis effects in vivo (Figures 4g and 4i).
