MicroRNAs (miRNAs) play an essential role in the tumorigenesis of gastric carcinoma (GC). MiR-429 has been recently reported to inhibit GC growth; however, whether miR-429 may also regulate the invasion of GC cells is unknown. Here, we showed that miR-429 levels were significantly decreased and ZEB1 and ZEB2 levels were significantly increased in GC specimens, compared to the paired adjacent non-tumor gastric tissue. Moreover, the levels of miR-429 and ZEB1 or ZEB2 inversely correlated in GC specimens. Bioinformatics analyses showed that miR-429 targeted the 3'-untranslated region of both ZEB1 and ZEB2 mRNA to inhibit their translation, which was confirmed by luciferase reporter assay. Overexpression of miR-429 inhibited ZEB1/2-mediated cell invasiveness, while depletion of miR-429 augmented it. Together, our data suggest that miR-429 suppression in GC promotes ZEB1/2-mediated cancer cell invasion.
