目的 本研究从细胞生物学角度检测二甲双胍对小鼠胰岛瘤MIN6的影响,并探讨此过程中包含的分子生物学机制。方法 MTT法检测不同浓度二甲双胍(1、2、5、10、20 mmol/L)对MIN6细胞活力的影响,细胞划痕实验检测二甲双胍对MIN6细胞迁移的影响,免疫印记实验检测此过程中细胞凋亡相关蛋白Bcl-2、Bax、caspase3表达的变化,及AMPK和JNK信号通路蛋白磷酸化水平的变化。结果 二甲双胍浓度大于10 mmol/L时可以抑制MIN6细胞的活力(P<0.01),降低其迁移能力(P<0.01),高浓度二甲双胍可以上调细胞内凋亡蛋白Bax(P<0.05)和p-AMPK的表达(P<0.05),降低抗凋亡蛋白Bcl-2的表达,增加caspase3剪切体(P<0.05)。同时,二甲双胍可以降低MIN6细胞内JNK信号通路的磷酸化水平(P<0.05)。结论 高浓度二甲双胍可以抑制MIN6细胞的增殖和迁移,其作用可能与降低了JNK信号的通路活化有关。

Objective This study aims to investigate the effect of metformin on proliferation and migration of MIN6 cells, and to explore the underlying mechanism. Methods The viability of MIN6 cells that were treated with various metformin (1,2,5,10 and 20 mmol/L) was detected by MTT assay. The migration of MIN6 cells was determined by wound-healing assay. Meanwhile, the proteins expression of Bcl-2, Bax, caspase3 and the phosphorylation of AMPK, JNK was detected by western bolt assay. Results The cell viability and the migration of MIN6 cells were decreased when the concentration of metformin above 10 mmol/L(P<0.01). The expression of apoptosis-related protein Bax(P<0.05) and p-AMPK(P<0.05)was up-regulated, anti-apoptosis-related protein Bcl-2 was down-regulated and cleaved caspase3 (P<0.05)was increased after high metformin treatment. At the same time, the phosphorylation of JNK was down-regulated by metformin(P<0.05). Conclusion High concertration of metformin may inhibit the proliferation and migration of MIN6 cells through suppressing the activation of JNK signaling pathway.

Objective To explore evaluation value of alkaline phosphatase in vascular calcification and osteoporosis in maintenance dialysis patients. Methods 186 patients in maintenance dialysis were enrolled in this study. The related clinical data was recorded. The examination of X-ray (lateral abdomens) was done to estimate vascular calcification in patients. Bone mineral density was measured by dual energy X-ray absorptiometry. The results above were analyzed by bivariate correlation analysis and receiver operator characteristic curve. Results By bivariate correlation analysis,serum alkaline phosphatase level was negatively associated with femoral neck bone mineral density, and was positively associated with abdominal aortas calcification scores. Abdominal aortas calcification scores were negatively associated with femoral neck bone mineral density. ROC curve revealed AUCs were respectively 0.777 and 0.701 for serum alkaline phosphatase level in diagnosis of osteoporosis and severe abdominal aortas calcification. Conclusion Alkaline phosphatase may be a good index to evaluate calcification and osteoporosis in maintenance dialysis patients.
