For instance, positive NOTCH1 staining was found in about half (43.9%) of the NSCLC tissues (n = 305, consisting of 210 squamous carcinomas and 95 adenocarcinomas), whereas only 15% of the normal lung tissues (n = 80) were positive for NOTCH1 staining [36]. The gene discussed is NOTCH1; the disease is non-small cell lung carcinoma.
