miR-324-3p promotes gastric cancer development by activating Smad4-mediated Wnt/beta-catenin signaling pathway

Background Emerging evidence suggested that miRNAs can function as oncogenes or tumor suppressors by regulating downstream target genes. miR-324-3p has been reported to function in several carcinomas, but its role in gastric cancer (GC) is still unknown. This study aims to explore the effects of miR-324-3p on the development of GC.
