摘要：

Diabetes may cause apoptosis in pancreatic islets. Berberine is an isoquinoline alkaloid used for its pharmacological functions including anti-inflammation. However, the berberine effect on pancreatic islets is still not clear. This study is aimed at clarifying the protective mechanism in berberine against islet cell apoptosis. This study established in vitro experimental models using streptozotocin (STZ)-treated primary pancreatic islet cells from ICR mice to unravel the protective mechanism of berberine on islets. The Bax/Bcl-2 (pro-/anti-apoptotic) genes expression in the islets was determined using real-time quantitative polymerase chain reaction assay. The results showed that berberine administration at one time or before STZ-stimulation significantly (P<0.05) down-regulated the Bax/Bcl-2 genes expression ratio, compared to those in STZ-treatment alone group. Our results suggest that berberine's anti-apoptotic effect on pancreatic primary islets is through down-regulating the Bax/Bcl-2 genes expression ratio in both concurrent and preventive manners.
