MALAT1 RNA was first discovered when studying gene expression in metastaticnon-small cell lung cancer (NSCLC) [13].MALAT1, also known as NEAT2 (nuclear-enriched abundant transcript 2), residesin the nucleoplasm in nuclear speckles (structures performing variousfunctions, the main one being the regulation of pre-mRNA splicing andtranscription) [14]. This evidence concerns the gene MALAT1 and small cell lung carcinoma.
