CYB561 and lung cancer: However, although many researchers believe that lncRNAs have great potential as biomarkers or therapeutic targets for lung cancer, but few have been experimentally validated and functionally annotated.24, 25, 26 In this study, we found that lnc‐CYB561‐5 was highly expressed in NSCLC and showed a close correlation with the proliferation, metastasis and metabolic reprogramming of lung cancer cells, suggesting that it might represent an independent prognostic biomarker in NSCLC.
