According to the Oncomine database data, both FTH1 (Fig. 1a) and FTL (Fig. 1b) levels were elevated in pancreatic tumor tissues compared with those in normal pancreatic tissues; however, Kaplan–Meier survival curves demonstrated that high levels of FTH1 (Fig. 1c) but not FTL (Fig. 1d) were associated with poor survival in patients with pancreatic cancer. Here, FTL is linked to pancreatic neoplasm.
