The expression level of circHIPK3 in gastric cancer tissues and cells. a, b The relative expression level of circHIPK3 was assessed with RT-qPCR assay in gastric cancer tissues and paired neighboring normal tissues, along with GES-1, HGC-27, and AGS cells. c, d RT-qPCR was applied to determine circHIPK3 and HIPK3 mRNA levels in HGC-27 and AGS cells. *P < 0.05
