TP53INP1 and glioblastoma: The eight genes that overlapped between the set of 31 genes that could distinguish TMZ-resistant from control GBM samples and the set of 27 genes in the two gene signatures predictive of OS in the GSE108474 and GSE7696 datasets were ANG, BACH1, CDKN2C, HMGA1, IFI16, PADI4, SDF4, and TP53INP1. Thus, these were genes in common between signatures of prognosis and of TMZ resistance.
