ABSTRACT
Distant metastasis is the predominant pattern of gastric cancer (GC) recurrence, and is the most common cause of cancerassociated mortality. Accumulating evidence has suggested that aberrant activation of epithelialmesenchymal transition has a crucial role in the genesis, invasion and metastasis of various types of cancer, including GC. Using Cell Counting kit8 and Transwell assays, the effects of microRNA (miR)205 on the proliferation, migration and invasion of NCIH87 GC cells were determined, and the potential underlying mechanisms were explored. The results of the present study demonstrated that miR205, which has been reported to function as a tumor suppressor in various types of cancer, significantly suppressed the migration and invasion of GC cells, which may be correlated with its suppressive effects on EMT. Upon transfection with miR205, the epithelial marker CDH1 (Ecadherin) was upregulated, and the mesenchymal markers CDH2 (Ncadherin) and vimentin were suppressed. Furthermore, zincfinger Eboxbinding homeobox factor1 (ZEB1) was identified as a putative target gene of miR205 in GC, which may be associated with its suppressive effects. The results of the present study may provide novel diagnostic and therapeutic options for the treatment of human GC.
