For example, tumor derived lncRNA H19 displays positive correlation with gefitinib resistance in patients with non-NSCLC [173]; lncRNA PART1 with similar geftinib resistance in esophageal squamous cell carcinoma (ESCC) [174]; lncRNA ARSR with sunitinib resistance in advanced renal cell carcinoma (RCC) [175]; lncRNA UCA1 expression with cetuximab-resistant CRC cells [176]. The gene discussed is UCA1; the disease is esophageal squamous cell carcinoma.
