Collectively, this is the first report demonstrating reciprocal interaction of miR‐34a‐5p‐ and HOTAIR‐mediated regulation of snail resulting in inhibition of EMT process by the combination of berberine and gefitinib suggesting that regulation of miR‐34a‐5p‐ and HOTAIR‐mediated inhibition of EMT may provide novel treatment paradigms for lung cancer. The gene discussed is HOTAIR; the disease is lung carcinoma.
