1rAAV/ABAD-DP-6His attenuates oxidative stressinduced injury of PC12 cells显示文摘Our previous studies have revealed that amyloid β(Aβ)-binding alcohol dehydrogenase(ABAD) decoy peptide antagonizes Aβ42-induced neurotoxicity. However, whether it improves oxidative stress injury remains unclear. In this study, a recombinant adenovirus constitutively secreting and expressing Aβ-ABAD decoy peptide(rAAV/ABAD-DP-6His) was successfully constructed. Our results showed that rAAV/ABAD-DP-6His increased superoxide dismutase activity in hydrogen peroxide-induced oxidative stress-mediated injury of PC12 cells. Moreover, rAAV/ABADDP-6His decreased malondialdehyde content, intracellular Ca2+ concentration, and the level of reactive oxygen species. rAAV/ABAD-DP-6His maintained the stability of the mitochondrial membrane potential. In addition, the ATP level remained constant, and apoptosis was reduced. Overall, the results indicate that rAAV/ABAD-DP-6His generates the fusion peptide, Aβ-ABAD decoy peptide, which effectively protects PC12 cells from oxidative stress injury induced by hydrogen peroxide, thus exerting neuroprotective effects.Mingyue Jia Mingyu Wang Yi Yang Yixin Chen Dujuan Liu Xu Wang Lei Song Jiang Wu Yu Yang 2014Neural Regeneration Research2014,9,5:3
2以β-淀粉样蛋白为靶点的阿尔茨海默病治疗途径显示文摘阿尔茨海默病(AD)的病因有很多,有研究证明β淀粉样蛋白(Aβ)在脑内的沉积是AD病理的始发因素和重要环节,是导致AD的关键因素。以Aβ为靶点治疗AD是新突破点。樊星 陈红 高雪峰 赵鹏 董贵成 2016中西医结合心血管病电子杂志2016,4,36:1
