TAP1 and pancreatic adenocarcinoma: Patients with low expression levels of TAP1 (z-score < −0.5) showed better overall survival rate (Figure 2g) and disease-free survival rate (Figure 2h) than patients with high expression levels of TAP1 (z-score > −0.5), suggesting that TAP1 exerted a cancer-promoting role in pancreatic adenocarcinoma.
