Although dispensable for normal physiology, MALAT1 is important for the regulation of cancer-related pathways regulation34 and is associated with several cancer signalling pathways including MAPK/ERK35, PI3K/AKT36, β-catenin/Wnt37, Hippo-YAP38, VEGF39, etc. We also checked the quality of exosome/body fluid-related scRNA-seq datasets. Here, MALAT1 is linked to cancer.
