ATG7 and gastric cancer: Otherwise, several studies also have reported that lncRNA BLACAT1 may be involved in chemoresistance. Huang et al. indicated that lncRNA BLACAT1 could regulate autophagy and promote chemoresistance of non-small-cell lung cancer cells via miR-17/ATG7 axis [29]. Wu et al. demonstrated that BLACAT1 promoted the oxaliplatin-resistance of gastric cancer through BLACAT1/miR-361/ABCB1 regulatory pathway, providing a brand new insight for the oxaliplatin-resistance of gastric cancer [30].
