Using the clinical samples from our NSCLC cohort and GSE18842 dataset, we demonstrated that aberrant expression of SREBP-1 and SCAP was associated with disease progression and a poor prognosis in lung cancer, thus indicating their potential clinical utility as reliable diagnostic or prognostic biomarkers and as potential molecular targets for the treatment of lung adenocarcinoma. This evidence concerns the gene SCAP and lung adenocarcinoma.
