Another lncRNA MALAT1 (metastasis-associated lung adenocarcinoma transcript 1), which was initially found to be highly expressed in lung cancer and was a favorable prognostic factor for the survival of patients with stage I non-small-cell lung cancer (NSCLC), was demonstrated to have a tumor suppressive role in glioma by attenuating ERK/MAPK-mediated growth and MMP2-mediated invasiveness [18]. Here, MMP2 is linked to lung cancer.
