MiR‐214‐3p has been reported to be involved in several biological functions and associated with growth, apoptosis, progression and survival.17, 18, 19 This shows that miR‐214‐3p may be a key therapeutic target for miRNA‐based therapies for cancer.23 In addition, HOTAIR also affects the miRNAs‐mediated suppression of target gene expression by competitive binding to miRNAs. The gene discussed is HOTAIR; the disease is cancer.
