KCNQ1OT1 and melanoma: Overexpression of KCNQ1OT1 contributed to the proliferation, migration, and invasion of melanoma and RB cells by sponging miR-153, and increasing MET proto-oncogene receptor tyrosine kinase (MET) and hypoxia-inducible factor-1α (HIF-1α) expression, respectively [41,77] (Table 1).
