Zhang et al. identified that ubiquitin-specific peptidase 47 (USP47) and Ras-related protein Rab-22A (RAB22A) were direct functional targets of miR-204-5p in GC and that miR-204-5p inhibited GC cell proliferation by downregulating USP47 and RAB22A [24]. This evidence concerns the gene RAB22A and gastric cancer.
