Article Title: Upregulation of NDUFAF2 in Lung Adenocarcinoma Is a Novel Independent Prognostic Biomarker

doi: 10.1155/2023/2912968

Figure Lengend Snippet: The expression of NDUFAF2 at the protein level in LUAD tissues was confirmed using clinical tissue and NSCLC cell lines. (a) Validation of the expression level of NDUFAF2 in LUAD and paired adjacent lung tissues was conducted using western blotting analysis. (b) Western blotting analysis was used to detect the protein expression level of NDUFAF2 in different NSCLC cell lines and normal lung epithelial cell line 2B. (c) IHC staining of NDUFAF2 was performed in adenocarcinoma tissue and paired adjacent normal lung tissue from typical clinical specimens. Representative images are shown. Scale bar, left, 200 μ m; right, 50 μ m.
