ERBB2 and glioma: Accumulated reports have demonstrated the role of HOTAIR in cellular processes as a ceRNA: HOTAIR can stimulate the development of glioma, serving as a ceRNA via sponging miR‐126‐5p33; HOTAIR promotes to the progression of gastric cancer by acting as a ceRNA of miR‐331‐3p, which is mediating HER2.34 Moreover, down‐regulation of HOTAIR decreased the expression of Vimentin and MMP‐9 but increased that of E‐cadherin through up‐regulation of miR‐204.
