Subsequently, we performed quantitative reverse-transcription polymerase chain reaction (qRT-PCR) to examine the expression levels of the seven key prognostic genes—CEBPB, TANK, MAT2B, TMEM165, CCDC167, CYFIP1, and COX17—in the CEBPB+CAF prognostic model in the tumor tissues. Here, CYFIP1 is linked to neoplasm.
