The autophagy inhibitors, such as the siRNA of Atg5 or Atg7, are always used to investigate the role of autophagy in regulating cell processes.41 In the present study, we selected Wortmannin (Wort), a famous autophagy inhibitor, to confirm the effect of Salid on the regulation of ERS-dependent autophagy in gastric cancer cells. This evidence concerns the gene ATG7 and gastric cancer.
