As several studies recently suggested that MALAT1 promotes proliferation and metastasis of various cancers by activating the RTK/MAPK/PI3K pathways (Wu et al, 2014; Dong et al, 2015; Xu et al, 2015), we tested possible correlation between Δsv-MALAT1 and various proteins involved in these signalling pathways. This evidence concerns the gene MALAT1 and cancer.
