FTH1 and pancreatic neoplasm: 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.
