MALAT1 and breast carcinoma: While the above MALAT1-miRNA interaction has been supposed to promote cancer, MALAT1 has been reported to exert tumor suppressive effects by sponging miRNAs miR‐17, 20a, and 106b and thereby decreasing the expression of epithelial cell adhesion molecule (EpCAM) and ITGB4 in colon and breast cancer cells (Kwok et al., 2018) (Table 1).
