TRIP13 and adenocarcinoma: As shown briefly in Figures 4(b)–4(f), the mRNA expression levels of 5 genes, namely, BIRC5, MCM4, CDC20, KIAA0101, and TRIP13, were significantly upregulated in TN adenocarcinomas (allP < 0.05) compared with those in non-TN adenocarcinomas, while the mRNA expression levels of 4 genes, namely, TOP2A (P = 0.259), UBE2C (P = 0.0569), AURKA (P = 0.0778), and KIF20 (P = 0.1634) were not upregulated in TN adenocarcinomas.
