Snehasikta Swarnakar (IICB, Kolkata) discussed unpublished data focussing on the role of matrix metalloproteases (MMPs) and endopeptidases in epithelial ovarian cancer, found that miRNA34a expression inhibited in vitro tumorigenesis and inversely correlated with MMP2 activity while the stage of ectopic endometrial cancer tissue positively correlated with MMP2 activity. The gene discussed is MMP2; the disease is ovarian carcinoma.
