OXCT1 and non-small cell lung carcinoma: As shown in Figure 1(a), lncRNA OXCT1-AS1 levels were significantly elevated in NSCLC cells (H23, HCC827, H1299, and A549) compared with that in BEAS-2B cells; among these cancer cell lines, H1299 and A549 cells showed the highest upregulation of lncRNA OXCT1-AS1 expression.
