NEAT1 and cancer: Increasing evidence has illustrated the important role of lncRNA in cancer drug resistance via acting as miRNA “sponge.” For instance, lncRNA NEAT1 up‐regulated in renal cell carcinoma tissue and NEAT1 knockdown increase the sensitivity of RCC cells to sorafenib by acting as a competitive sponge for miR‐34a through the miR‐34a/c‐Met axis.27
