The process identified with the lowest FDR, among the three, was the ECM organization involving several less-abundant proteins, such as decorin and tryptase-1, with the lowest levels in both tumor regions, basigin in the deep part of the tumor, and lumican, mimecan, and HPLPN1 on the surface of the tumor (Table 2). The gene discussed is TPSAB1; the disease is neoplasm.
