PG - 41-51 AB - A malignant insulinoma (LOHG-I), a carcinoid of the lung (LOHG-L), a parathyroid adenoma (LOHG-NSA), and a fibroma (LOHG-F) were obtained from a patient with multiple endocrine neoplasia type 1 (MEN1). Long-term cultures were established. Essential neurobiological properties of the cell lines were proven immunocytochemically and by electron microscopy. Molecular analysis of the germline DNA showed a 4 bp deletion in exon 3 of the MEN1 gene. Cytogenetic and CGH analyses of the tumors/tumor cell lines revealed diploidy and balanced and unbalanced structural aberrations different for each tumor. Chromosomes 6q21, 11q and 17q were most frequently involved in clonal structural aberrations.
