Figure Lengend Snippet: A qPCR analysis of circDHX8 with AGO2-RIP. B RIP analysis of the relative interplay between circDHX8 and ATG2B. C Overlapping analysis of differentially expressed genes (DEGs) between the circDHX8-OE and control groups with DEGs from CPTAC. D qPCR analysis of MYC, PPP1R15A, CDKN1A, RAB7A, FOS, ATG2B, and PRKCQ after circDHX8 overexpression. E Western blotting analysis of the protein levels of MYC, PPP1R15A, CDKN1A, RAB7A, FOS, ATG2B, and PRKCQ after circDHX8 overexpression. F Protein stability of ATG2B was assessed by western blotting. G The effect of circDHX8 and chloroquine on ATG2B protein levels was analyzed by western blotting. H Western blotting assays showed that circDHX8 could suppress the ubiquitination of ATG2B. I Colony-forming capacity of MKN45 and AGS cells. J Transwell assays for migration and invasion in MKN45 and AGS cells. * P < 0.05, ** P < 0.01 and *** P < 0.001.
