SLC30A6 and neoplasm: To gain a deeper understanding of the expression profiles, we evaluated the proportion of patients with protein expression of 21 SLC proteins in tumor tissues as well as in normal endocrine and exocrine glandular cells, as shown in Figure 3B. A significant proportion of patients showed elevated expression levels of the following proteins in PDAC: SLC39A10, SLC22B5, SLC55A2, SLC30A6, SLC2A3, SLC35B2, and SLC6A14.
