Clinical samples were collected, after which the expression levels of KLF1, LINC02159, and dynein cytoplasmic 1 heavy chain 1 (DYNC1H1) in tissues and cells were initially detected, and NSCLC cell proliferation and invasion were measured when KLF1 was up‐ or downregulated. This evidence concerns the gene KLF1 and non-small cell lung carcinoma.
