NSRP1 and cancer: In agreement with this, analysis of genetic alterations in the human NSRP1 gene in patients with different cancer types using TCGA PanCancer Atlas database and the cBioPortal online tool (www.cbioportal.org) demonstrated that NSRP1 was altered in 178 samples from 10,953 patients, and was frequently amplified in several different cancer types (Supplementary Figure S7A).
