摘要: 目的: 探讨鲨鱼肝活性肽S-8300 的抗糖尿病与细胞保护作用。方法: 用流式细胞仪和原位缺口末端标记(TUNEL) 法分析S-8300 对链佐霉素(STZ)诱导小鼠糖尿病模型胰岛细胞凋亡的影响;用MTT法检测S-8300 对损伤小鼠胰岛素瘤β-cell 株(NIT-1)的影响。结果: S-8300 能显著降低STZ 诱导的胰岛细胞凋亡, 对STZ 损伤的小鼠胰岛素瘤β 细胞具有明显的修复和保护作用。结论: S-8300 的抗STZ 损伤与其对凋亡细胞的保护作用有关, 可能是其降血糖作用的机制之一。

Abstract: AIM: The purpose of this study was to evaluate the effect of anti-diabetes and cell protection of a new peptide S-8300 on streptozotocin diabetic mice. METHODS: The apoptosis induced by streptozotocin (STZ) in the diabetic mice was tested through cytometer and TUNEL technology. The biological activity was measured by MTT assay with mouse insulinoma β-cell line (NIT-1) which was exposed to the toxins STZ. RESULTS: S-8300 obviously reduced the rate of apoptosis in injured pancreas induced by STZ and it could also protect the structure integrity and recover the damage of NIT-1 cell after exposed to the toxin of STZ. CONCLUSION: The hypoglycemic mechanism of the anti-apoptotic effect of S-8300 may be related with the protective activity anainst the apoptosis.

Key words: S-8300, diabetes, apoptosis
