MALAT1 and breast cancer: Other lncRNAs with tumour suppressor characteristics for certain type of cancers are: X–inactive specific transcript (XIST) lncRNA, a tumour suppressor in breast, cervical and ovarian cancers (34); GAS5 lncRNA that regulates cell proliferation, growth arrest, and apoptosis (35); CTD903 lncRNA that inhibits EMT (36); TUSC7 lncRNA that is involved in transcription and regulation of miRNAs (37); MALAT1 a tumor suppressor lncRNA downregulated in breast cancer (38).
