The results showed that the survival rate of the cell lines with lncRNA TRERNA1 high expression (A549/H292) was higher than that of cell lines with lncRNA TRERNA1 low expression (PC9/HCC827; Figure 1B), indicating that TRERNA1 was positively correlated with radiation tolerance of NSCLC cells. The gene discussed is TRERNA1; the disease is non-small cell lung carcinoma.
