Research output: Contribution to journalArticlepeer-review


Three transgenic mouse models which proved to develop endocrine tumours are reviewed and discussed. The neoplasms were induced through the production of the transforming oncoprotein simian virus 40 (SV40) large T-antigen. The SV40/metallothionein-growth hormone (MGH), the insulin/SV40 (INS/SV40) and the vasopressin/SV40 (AVP/SV40) transgenic mice models all developed endocrine tumours of pancreas mainly composed of insulin-producing B cells, with a minor PP cell component. In the pancreata of INS/SV40 and AVP/SV40 transgenic mice, non-tumour lesions (hyperplasia and dysplasia) were also described. AVP/SV40 transgenic mice presented tumour genesis in anterior pituitary too. The usefulness of transgenic mouse models in reproducing human pathology is outlined with special reference to genetically dependent tumours.
