FBXO22 and pancreatic intraductal papillary-mucinous neoplasm: The results indicated that FBXO20 was highly expressed in these three kinds of precancerous lesions (IPMA, IPMC, and IPMN) in comparison to normal pancreatic tissues, and FBXO20 had the highest expression level among these three pathological types, while FBXO22 was downregulated in IPMA compared with corresponding normal tissues (Figure 3E).
