Abstract

ABSTRACT PI 3-kinase α (PI3Kα) is a lipid kinase that converts phosphatidylinositol-4,5-bisphosphate (PIP2) to phosphatidylinositol-3,4,5-triphosphate (PIP3). PI3Kα regulates a variety of cellular processes such as nutrient sensing, cell cycle, migration, and others. Heightened activity of PI3Kα in many types of cancer made it a prime oncology drug target, but also raises concerns of possible adverse effects on the heart. Indeed, recent advances in preclinical models demonstrate an important role of PI3Kα in the control of cytoskeletal integrity, Na+ channel activity, cardioprotection, and prevention of arrhythmias.

PI3Kα在心脏保护中的作用:细胞骨架、晚期Na+电流和心律失常的机制

PI3Kα (PI3Kα)是一种脂质激酶，可将磷脂酰肌醇4,5-二磷酸(PIP2)转化为磷脂酰肌醇3,4,5-三磷酸(PIP3)。PI3Kα调节多种细胞过程，如营养感知、细胞周期、迁移等。PI3Kα在多种癌症中的活性升高使其成为主要的肿瘤药物靶点，但也引起了对心脏可能产生不良影响的担忧。事实上，临床前模型的最新进展表明，PI3Kα在控制细胞骨架完整性、Na+通道活性、心脏保护和预防心律失常方面发挥了重要作用。
