PDGFC and metastatic neoplasm: We analysed the expression level differences of five shorter survival-associated genes (CTHRC1, NTM, PDGFC, PDLIM3, and SLC16A3) and one longer survival-associated gene (FBN2) among the normal fibroblast (n = 9), primary tumor fibroblast (n = 14), and metastatic tumor fibroblast (n = 11) samples of GSE46824 [18].
