An acidic pH and activation of phosphoinositide 3-kinase stimulate differentiation of pancreatic progenitors into insulin-producing cells

Popis výsledku v původním jazyce

Adult pancreatic nonendocrine cells represent a potential alternative source of insulin-producing tissue for the treatment of diabetes. Differentiation of these cells is regulated by various signaling pathways including the phosphoinositide 3-kinase (PI3K) pathway. Therefore, we evaluated the effect of PI3K on this process. Compared with untreated cells the differentiation of human nonendocrine pancreatic cells into insulin-producing elements was increased after treatment with IGF-1, EGF, and Exendin-4,growth factors known to be activators of the PI3K pathway (12.2 ? 3.2% vs 9.1 ? 3.2%). Treatment with PI3K pathway inhibitor wortmannin reduced the number of differentiated beta cells from 9.1 ? 3.2 to 0.7 ? 0.4%. Reverse transcriptase polymerase chainreaction (RT-PCR) analysis revealed that insulin-like growth factor-1 (IGF-1), epidermal growth factor (EGF), and Exendin-4 significantly increased the expression of the transcription factor neurogenin-3, whereas the expressions of pancre
