Akt与心肌保护的研究进展及临床启示

心肌保护是心脏疾病治疗的研究热点之一。多种生长因子对心脏有保护作用,使其免受局部缺血及其他损伤带来的损害。虽然这些心肌保护因子下游的转导通路很复杂,但在很多情况下,Akt的激活是一个共同的特征。它在调节各种生长因子和其他胞外刺激诱导的心肌细胞存活、生长、增殖、保持功能和营养物质代谢上发挥了重要作用。通过追踪最近的研究进展以更好地理解Akt在心肌保护中发挥的作用,讨论这些研究的临床启示。关键词:Akt,心肌保护,信号转导通路

Developments and Clinical Implications of Reseach on Akt and Cadioprotection

Akt is thought to be a key mediator of signal transduction processes, it plays important roles in regulating cell survival, growth, proliferation,function and nutrient metabolism in heart in response to growth factors and other extracellular stimuli. To survey recent developments in understanding the roles of Akt in cardioprotection noted above. Finally, the clinical implications of these studies will be considered.
