Targeting the cell cycle inhibitor p57Kip2 promotes adult human β cell replication

Abstract excerpt

Children with focal hyperinsulinism of infancy display a dramatic, non-neoplastic clonal expansion of β cells that have undergone mitotic recombination, resulting in paternal disomy of part of chromosome 11. This disomic region contains imprinted genes, including the gene encoding the cell cycle inhibitor p57Kip2 (CDKN1C), which is silenced as a consequence of the recombination event. We hypothesized that...
