MALAT1 and gastric cancer: miR‐30e also interacts with other lncRNAs to negatively regulate cancer progression such as oncogenic lncRNA DLEU2 that promoted esophageal cancer through the miR‐30e/E2F7 axis [62] and MALAT1 which acted as a molecular sponge of miR‐30e to regulate ATG5 expression and autophagy in gastric cancer [63].
