Long noncoding RNA ZMIZ1‐AS1 promotes gefitinib resistance via binding to hnRNPA1
Abstract To gain an insight into the molecular mechanisms of gefitinib resistance in nonsmall cell lung cancer, we screened out the long noncoding RNA related to gefitinib resistance through microarray data in gefitinib‐sensitive and resistant cells. lncRNA ZMIZ1‐AS1 was significantly upregulated in...
