X Zhang, JP Gaspard, Y Mizukami, J Li, F Graeme- … - Diabetes, 2005 - Am Diabetes Assoc Cyclin D1 can stimulate proliferation by driving cells from the G1 into the S-phase of the mammalian
cell cycle. Previous animal studies have implicated the G1-S transition as a key regulatory checkpoint
governing the proliferation of pancreatic islet cells. We expressed cyclin D1 in the β-cells ... Cited by 32 - Related articles - All 5 versions
I Cozar-Castellano, M Weinstock, M Haught… - Diabetes, 2006 - ncbi.nlm.nih.gov We hypothesized that combined transgenic overexpression of hepatocyte growth factor
(HGF) and placental lactogen in islets would lead to even greater increases in beta-cell mass
and replication than either growth factor alone. This did not occur, suggesting that ... Cited by 22 - Related articles - BL Direct - All 2 versions

protein (pRb), and this is regulated in part by the activities of cyclin-dependent kinase (cdk)-4
and the D cyclins. Surprisingly, given the potential importance of ß-cell replication for islet ... Cited by 57 - Related articles - BL Direct - All 4 versions

for normal regulation of β-cell proliferation, mass, and function. The retinoblastoma protein,
pRb, is positioned at the very end of a cascade of these regulatory proteins and is ... Cited by 12 - Related articles - BL Direct - All 5 versions
