Expression data from pancreatic islets from Men1flf RIP-Cre mice, Rbp2flf RIP-Cre mice, Men1flf Rbp2flf RIP-Cre mice and matched control.

ABSTRACT: The menin tumor suppressor protein (Men1) is deficient in many endocrine tumors and forms an active complex with MLL family histone methyltransferases. This Men1 complex promotes histone H3 lysine 4 trimethylation at target loci including homeobox genes and cyclin-dependent kinase inhibitor genes. The loss of Men1 may be tumorigenic because it leads to decreased histone H3 lysine 4 trimethylation resulting in expressional changes of specific genes. Reversing tumorigenesis induced by a Men1 deficiency might be achieved by inhibition of histone H3 lysine 4 demethylase Rbp2 (Kdm5a). To this end, pancreatic islets from Men1f|f, Rbp2f|f and Men1f|f Rbp2f|f mice were expression profiled to determine what transcriptional changes induced by a Men1 deficiency are reversed by the loss of Rpb2.
