We detected that the expression level of GABARAPL1 and ATG13 were reduced in miR-133a-3p mimics transfected MKN-45 and BGC-823 cells, whereas the GABARAPL1 and ATG13 expression level increased in miR-133a-3p inhibitors transfected GC cells. This evidence concerns the gene GABARAPL1 and gastric cancer.
