Deregulation of RAB20 expression was associated with various types of human malignancies: RAB20 overexpression was pronounced in pancreatic cancer cell lines and in primary pancreatic carcinoma [94], in exocrine pancreatic carcinoma, and in preneoplastic pancreatic tissue compared with normal pancreatic cells [94]. The gene discussed is RAB20; the disease is exocrine pancreatic carcinoma.
