摘要:
目的:研究多聚ADP核糖聚合酶(PARP)阻滞剂3-氨基苯甲酰胺(3-AB)对心力衰竭(HF)大鼠心肌白细胞介素-10(IL-10)、肿瘤坏死因子-α(TNF-α)水平及对PARP和凋亡诱导因子(AIF)蛋白表达的影响。方法:结扎135只成年雄性Wistar大鼠冠状动脉前降支6周制备HF模型,随机分为HF组、3-AB治疗组(3-AB组)和Sham组。治疗组应用3-AB治疗(30 mg/kg)。治疗2、4、6周后采用放射免疫法测定大鼠心肌IL-10、TNF-α水平,采用免疫组化方法检测心肌PARP和AIF蛋白表达变化。结果:IL-10水平变化:与Sham组相比,HF组各时间点明显增高(P<0.05),3-AB组较HF组各相同时间点明显降低(P<0.05);TNF-α水平:HF组各时间点均较Sham组明显增高(P<0.05),而3-AB组较HF组各相同时间点明显降低(P<0.05)。PARP蛋白表达:HF组各时间点均较Sham组增加(P<0.05),3-AB组各时间点均较HF组明显减少(P<0.05)。AIF蛋白表达:HF组各时间点较Sham组增加,3-AB组各时间点较HF组明显减少(P<0.05)。结论:3-AB可抑制IL-10、TNF-α的释放;抑制PARP和AIF蛋白表达,从而抑制炎症反应和细胞凋亡,对HF大鼠心肌细胞发挥保护作用。
Abstract:
AIM:To investigate the effects of 3-aminobenzamide (3-AB) on interleukin-10 (IL-10), levels of tumor necrosis factor-α (TNF-α) and expression of PARP and apoptosis-inducing factor (AIF) on cardiocytes in rats with heart failure (HF). METHODS: One hundred and thirty-five adult Wistar rats underwent 6-w left anterior descending artery ligation to be models of HF. Rats were divided into HF group, 3-AB group and sham-operated group. Rats in 3-AB group received 3-AB (30 mg/kg) by intraperitoneal injection. Myocardial IL-10 and TNF-α levels in the rats were measured by radioimmunity and changes of expressions of PARP and AIF protein were measured by immunohistochemical staining in each group after treatment with 3-AB at 2-, 4- and 6-w. RESULTS: Compared with those in sham-operated rats, myocardial IL-10 levels and myocardial TNF-α levels in HF group increased 2-, 4- and 6-w after treatment and compared with those in the HF groups, both markedly decreased at the same time points (P<0.05). Compared with those in sham groups, expressions of PARP and AIF increased in HF groups and expressions of PARP and AIF were significantly suppressed in 3-AB in positive cells at the same time points (P<0.05). CONCLUSION: The present findings indicate that 3-AB could lower IL-10 and TNF-α concentrations and inhibit inflammatory reaction and apoptosis by decreasing PARP and AIF expressions, thus protecting cardiocytes in rats with HF.
