Background Suppressor of cytokine signaling （SOCS） proteins are inhibitors of cytokine signaling pathway involved in negative feedback loops. Although SOCS1 is an important intracellular suppressor of apoptosis in a variety of cell types, its role in cytokine-induced pancreatic β-cell apoptosis remains unclear. The present study investigated potential effects of SOCS1 on the cytokine-induced pancreatic β-cell apoptosis.

Objective Interferon-γ （IFN-γ） plays an important role in apoptosis and was shown to increase the riskof diabetes. Visfatin, an adipokine, has anti-diabetic, anti-tumor, and regulating inflammatoryproperties. In this study we investigated the effect of visfatin on IFN-γ-induced apoptosis in ratpancreatic β-*** The RINm5F （rat insulinoma cell line） cells exposed to IFN-γ were treated with or withoutvisfatin. The viability and apoptosis of the cells were assessed by using MTT and flow cytometry. Theexpressions of mRNA and protein were detected by using real-time PCR and western blot *** The exposure of RINm5F cells to IFN-γ for 48 h led to increased apoptosis percentage of thecells. Visfatin pretreatment significantly increased the cell viability and reduced the cell apoptosisinduced by IFN-γ. IFN-γ-induced increase in expression of p53 mRNA and cytochrome c protein,decrease in mRNA and protein levels of anti-apoptotic protein Bcl-2 were attenuated by visfatinpretreatment. Visfatin also increased AMPK and ERK1/2 phosphorylation and the anti-apoptotic actionof visfatin was attenuated by the AMPK and ERK1/2 *** These results suggested that visfatin protected pancreatic islet cells against IFN-γ-inducedapoptosis via mitochondria-dependent apoptotic pathway. The anti-apoptotic action of visfatin ismediated by activation of AMPK and ERK1/2 signaling molecules.

目的探讨4-苯基丁酸(4-PBA)对2型糖尿病(T2DM)大鼠的治疗作用及其抗胰腺β细胞凋亡的作用机制。方法高脂饮食喂养加小剂量链脲佐菌素(STZ)腹腔注射建立大鼠T2DM模型,造模成功后第10天灌胃给予4-PBA 20 d。用real-time PCR和Western blot法检测内质网(ER)应激相关分子CHOP、GRP78、caspase-3、Bax、Bcl-2和细胞色素C的mRNA及蛋白表达水平,同时检测MAPK通路相关蛋白的磷酸化水平。结果高脂喂养和T2DM组大鼠胰岛β细胞出现明显的凋亡,4-PBA治疗显著降低caspase-3的活性,减轻了凋亡。高脂喂养和T2DM组大鼠CHOP、Bax和细胞色素C的mRNA及蛋白表达水平显著升高,Bcl-2的表达降低(P<0.05)。4-PBA治疗显著降低了CHOP的表达,但对GRP78的表达没有影响;4-PBA治疗降低Bax和细胞色素C的mRNA及蛋白表达水平,并增加了Bcl-2的表达(P<0.05)。T2DM组可见ERK1/2磷酸化的增加,4-PBA治疗后降低了ERK1/2的磷酸化水平(P<0.05)。结论 4-PBA通过CHOP途径减轻高脂喂养和STZ导致ER应激增加诱导的胰岛β细胞凋亡,进而抑制了下游的线粒体途径,最终减轻ER应激诱导的胰岛β细胞凋亡,这一过程可能还与ERK1/2途径有关。
