SLC39A14 and cancer: Blinded pathological analysis showed ZIP14 positivity in the atrophic muscle fibers from 10 of 10 (100%) cachectic PDAC patients compared to 3 of 13 (23.1%) non-cachectic patients, which included 4 non-cachectic PDAC patients and 9 non-cachectic non-cancer patients (Pearson’s chi-square test: p < 0.0001) (Figure 4E).
