MALAT1 and thyroid cancer: As for investigating lncRNAs SNPs and thyroid cancer, several studies have investigated possible links between lncRNAs SNPs and PTC, establishing, for example, that lncRNAs BANCR, PTCSC3, and MEG3 are downregulated and have tumor suppressor roles in thyroid cancer, whereas lncRNAs CDKN2B Antisense RNA 1 (ANRIL), MALAT1, HOTAIR, and HIT000218960 are upregulated and function as oncogenes [102,103,104,105,106,107,108,109].
