MMP3 and breast neoplasm: By integrated analysis of genes regulated by miR-18a under normoxia using a data set from this study [GEO:GSE45362], miRNA target sites, expression correlation of mRNA and miRNA, and correlation with DMFS of patients with basal-like breast tumors, we discovered that miR-18a potentially targets the prometastatic gene matrix metallopeptidase 3 (MMP3).
