We also tested the specificity of the FKBP1A gene by comparing mRNA levels with other cancer-related digestive systems, including pancreatic cancer (N = 8), esophageal cancer (N = 5), stomach cancer (N = 5), colon cancer (N = 5), and liver cancer (N = 5). Here, FKBP1A is linked to malignant colon neoplasm.
