To further clarify the involvement of autophagic degradation of β-catenin in KLF13-suppressed cell proliferation of gastric cancer, we detected the effects of autophagy inhibition on expressions of CCND1 and MYC as well as cell proliferation by adding CQ into the cells transfected with KLF13 plasmid or not. Here, KLF13 is linked to gastric cancer.
