MMP9 and gastric cancer: In addition, this gene can be used as a metastatic predictor and prognostic marker for GC.36 In a similar study, increasing miRNA-324 expression leads to MMP-9 reduced expression and inhibited the migration of colorectal cancer cells.37 Considering the findings of the current study, it could be assumed that miR-193a-5p, maybe by interaction with the 3′-UTR of MMP-9 and vimentin mRNAs regulates other metastasis-associated genes affecting the migration of the cells.
