miR-450b-3p is lowly expressed in GC tissues and cell lines. a qRT-PCR was used to detect the expression level of miR-450b-3p in GC tissues and paracancerous tissues; b qRT-PCR was used to detect the expression level of miR-450b-3p in GC cell lines; c qRT-PCR was used to detect the difference expression of miR-450b-3p in tissue samples of GC patients with different pathological stage; d qRT-PCR was used to detect the difference expression of miR-450b-3p in tissue samples of GC patients with different tumor size; e qRT-PCR was used to verify the transfection efficiency of miR-450b-3p after transfection of NC mimic and miR-450b-3p mimic in AGS and BGC-823 cell lines. Data are mean ± SD, *p < 0.05, **p < 0.01, ***p < 0.001
