To determine the alteration of gene expression in mouse Men1 insulinomas at different stages during tumour initiation and progression, mRNAs were isolated from hand-picked pancreatic islets of two Men1 F/F mice, two Men1 β-cell-specific mutant

Introduction Pancreatic endocrine tumours (PETs) are rare neoplasms arising from pancreatic islet cells. PETs are classified as ‘functioning’ (F) or ‘non-functioning’ (NF) depending on the presence or absence of a syndrome due to
