The PI3K pathway plays an important role in key cellular functions such as cell growth, proliferation and survival. Genetic and epigenetic alterations in different pathway components lead to aberrant pathway activation and have been observed in high frequencies in various tumor types. Consequently, significant effort has been made to develop antineoplastic agents targeting different nodes in this pathway. Additionally, PI3K pathway status may have predictive and prognostic implications, and may contribute to drug resistance in tumor cells. This article provides an overview of our current knowledge of the PI3K pathway with an emphasis on its application in cancer treatment.
PI3K 通路在细胞的重要功能中发挥着重要作用,如细胞生长、增殖和存活。不同通路成分的遗传和表观遗传改变导致异常通路激活,并在各种肿瘤类型中高频观察到。因此,人们做出了巨大努力来开发针对该通路不同节点的抗肿瘤药物。此外,PI3K 通路状态可能具有预测和预后意义,并可能导致肿瘤细胞的耐药性。本文概述了我们目前对 PI3K 通路的认识,重点介绍其在癌症治疗中的应用。
