For instance, lncRNA urothelial carcinoma-associated 1 (UCA1) overexpression enhanced, whereas UCA1 knockdown impaired the proliferation and colony formation of NSCLC cells; UCA1 targetted and suppressed the miR-193a-3p level, and promoted the expression of human epidermal growth factor receptor 4, an identified target gene of miR-193a-3p [22]. The gene discussed is ERBB4; the disease is non-small cell lung carcinoma.
