Abstract

Alzheimer's disease (AD) is presently the 6th major cause of mortality across the globe. However, it is expected to rise rapidly, following cancer and heart disease, as a leading cause of death among the elderly peoples. AD is largely characterized by metabolic changes linked to glucose metabolism and age-induced mitochondrial failure. Recent research suggests that the glycolytic pathway is required for a range of neuronal functions in the brain including synaptic transmission, energy production, and redox balance; however, alteration in glycolytic pathways may play a significant role in the development of AD. Moreover, it is hypothesized that targeting the key enzymes involved in glucose metabolism may help to prevent or reduce the risk of neurodegenerative disorders. One of the major pro-glycolytic enzyme is 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase-3 (PFKFB3); it is normally absent in neurons but abundant in astrocytes. Similarly, another key of glycolysis is glyceraldehyde-3-phosphate dehydrogenase (GAPDH) which catalyzes the conversion of aldolase and glyceraldehyde 3 phosphates to 1,3 bisphosphoglycerate. GAPDH has been reported to interact with various neurodegenerative disease-associated proteins, including the amyloid-β protein precursor (AβPP). These findings indicate PFKFB3 and GAPDH as a promising therapeutic target to AD. Current review highlight the contributions of PFKFB3 and GAPDH in the modulation of Aβand AD pathogenesis and further explore the potential of PFKFB3 and GAPDH as therapeutic targets in AD.

摘要

阿尔茨海默病(AD)目前是全球第六大主要死亡原因。然而,随着癌症和心脏病之后,它预计将迅速成为老年人死亡的主要原因。AD 的主要特征是与葡萄糖代谢和年龄引起的线粒体衰竭相关的代谢变化。最近的研究表明,糖酵解途径对于大脑中的一系列神经元功能是必需的,包括突触传递、能量产生和氧化还原平衡;然而,糖酵解途径的改变可能在 AD 的发展中起重要作用。此外,有人假设靶向参与葡萄糖代谢的关键酶可能有助于预防或降低神经退行性疾病的风险。主要的促糖酵解酶之一是 6-磷酸果糖-2-激酶/果糖-2,6-二磷酸酶-3(PFKFB3);它通常不存在于神经元中,但在星形胶质细胞中丰富。同样,糖酵解的另一个关键是甘油醛-3-磷酸脱氢酶(GAPDH),它催化醛缩酶和甘油醛 3 磷酸转化为 1,3 双磷酸甘油酸。已经报道 GAPDH 与各种与神经退行性疾病相关的蛋白质相互作用,包括淀粉样β蛋白前体(AβPP)。这些发现表明 PFKFB3 和 GAPDH 是 AD 的有前途的治疗靶点。目前的综述强调了 PFKFB3 和 GAPDH 在调节 Aβ和 AD 发病机制中的作用,并进一步探讨了 PFKFB3 和 GAPDH 作为 AD 治疗靶点的潜力。
