The transcriptional response of the islet to pregnancy in mice.

ABSTRACT: The inability of the ss-cell to meet the demand for insulin brought about by insulin resistance leads to type 2 diabetes. In adults, ss-cell replication is one of the mechanisms thought to cause the expansion of ss-cell mass. Efforts to treat diabetes require knowledge of the pathways that drive facultative ss-cell proliferation in vivo. A robust physiological stimulus of ss-cell expansion is pregnancy and identifying the mechanisms underlying this stimulus may provide therapeutic leads for the treatment of type 2 diabetes. The peak in ss-cell proliferation during pregnancy occurs on d 14.5 of gestation in mice. Using advanced genomic approaches, we globally characterize the gene expression signature of pancreatic islets on d 14.5 of gestation during pregnancy. We identify a total of 1907
