At protein level, positive expression of MKI67 in NSCLC tumors while negative expressed in normal lung tissues was shown in HPA (Supplementary Figures S3E–G) and MKI67 overexpression in NSCLC tumors was also confirmed in CPTAC lung cancer dataset (Supplementary Figure S3H, p < 0.01). The gene discussed is MKI67; the disease is non-small cell lung carcinoma.
