Accumulating studies have revealedthat MALAT1 not only plays a pivotal role in NSCLCprogression, but also promotes other kinds of tumors.Zhang et al. found that serum exosome-derived lncRNAMALAT1 facilitated the tumor growth and migration,while it reduced apoptosis rate in NSCLC (26). Here, MALAT1 is linked to non-small cell lung carcinoma.
