Zhang et al., (2015) found the decreased expression levels of miR153 in tissue samples of gastric cancer by suppressing SNAI1 and EMT in the cells of gastric cancer.miR 153 upregulation diminished cell migration and invasion of MKN-45 Cells.Meanwhile miR153 downregulation has incentivized cell migration and invasion of SGC-7901. This evidence concerns the gene SNAI1 and gastric cancer.
