最近的研究表明,通过磷脂酰肌醇 3'-激酶 (PI3K) 通路的组成性信号传导是乳腺癌患者治疗抵抗的一个原因。这意味着具有异常 PI3K 信号传导的肿瘤患者可能会受益于靶向途径抑制剂。第一个进入临床的药物是雷帕霉素类似物。这些化合物抑制下游 PI3K 效应子 mTOR(雷帕霉素的哺乳动物靶标)。本期乳腺癌研究中发表的一项研究表明,最近开发的磷酸肌醇依赖性蛋白激酶 1 抑制剂(PI3K 通路的更近端靶标)可能为乳腺癌治疗提供有效抑制 PI3K 通路的替代途径。
Recent studies indicate that constitutive signaling through the phosphatidylinositol 3'-kinase (PI3K) pathway is a cause of treatment resistance in breast cancer patients. This implies that patients with tumors that exhibit aberrant PI3K signaling may benefit from targeted pathway inhibitors. The first agents to make it to the clinic are the rapamycin analogs. These compounds inhibit the downstream PI3K effector mTOR (mammalian target of rapamycin). A study presented in this issue of Breast Cancer Research suggests that recently developed inhibitors of phosphoinositide-dependent protein kinase 1, a more proximal target of the PI3K pathway, may provide an alternative route to effective PI3K pathway inhibition for breast cancer treatment.
