Seven of these predicted proteins (NCAM1, CNTN1, SCG2, CADM1, IL-8, NPTX1, and APOD) were identified in five databases (SignalP 4.1, SecretomeP 2.0, Vesiclepedia, Human Cancer Secretome, and Plasma Proteome), giving support to their relevance in NSCLC. The gene discussed is NCAM1; the disease is cancer.
