MALAT1 (Metastasis Associated Lung Adenocarcinoma Transcript 1) also known as NEAT2 (Nuclear-Enriched Abundant Transcript 2) is an infrequently spliced long non-coding RNA, which is highly conserved amongst mammals and highly expressed in the nucleus.[3] It regulates the expression of metastasis-associated genes.[4] It also positively regulates cell motility via the transcriptional and/or post-transcriptional regulation of motility-related genes.[5] MALAT1 may play a role in temperature-dependent sex determination in the Red-eared slider turtle (Trachemys scripta).[6]

Expression in alcoholic brains

[edit]

Transcripts of MALAT1 are significantly increased in the cerebellum of human alcoholics, as well as in similar regions of rat brains after the withdrawal of ethanol vapours. This alcohol-induced upregulation of MALAT1 may be responsible for differential expression of a number of proteins which contribute to ethanol tolerance and dependency in humans.[7]

Prognostic potential in cancer

[edit]

Elevated MALAT1 expression is correlated with poor overall survival in various types of cancer, suggesting that this gene is a prognostic factor for different types of cancer.[8][9]
