Western blotting showed that Dcf1 inhibited the expression of PARL (Figure 3A), and the subcellular colocalization of BECN1‐Bcl‐2 in endoplasmic reticulum (ER) was not changed by Dcf1 (Figure S4A), suggesting that autophagy and apoptosis occurred in glioblastoma cells simultaneously. This evidence concerns the gene BECN1 and glioblastoma.
