In glioblastoma, MALAT1 acts as a competing endogenous RNA (ceRNA) for miR-199a to weaken the inhibitory effect of miR-199a on ZHX1, which strengthens tumor proliferation and progression [8], while MALAT1 also promotes autophagy-mediated chemoresistance by regulating miR-23b-3p/ATG12 axis in gastric cancer [9]. Here, MALAT1 is linked to glioblastoma.
