A number of genes that were poor prognostic markers have been identified in CRC patients (e.g., NUCKS1, BNIP3, PDGFC, OPG) using microarray analysis; their prognostic significance was subsequently assessed in surgically resected CRC subjects by mRNA and/or immunohistochemical (IHC) analyses [6–9]. The gene discussed is PDGFC; the disease is colorectal carcinoma.
