Abstract

Activation of the phosphoinositide 3 kinase (PI3K)/AKT pathway is frequently implicated in resistance to anticancer therapies. PI3K inhibitors can restore sensitivity to standard breast cancer therapies, including endocrine therapy, HER2-targeted agents, and chemotherapy. Our previous research showed that econazole, a novel PI3Ka inhibitor, inhibits the PI3K/AKT pathway and induces apoptosis in lung cancer cells. In this study, econazole showed significant cytotoxic activity against Adriamycin-resistant breast cancer cells and . Additionally, econazole significantly sensitized MDA-MB-231 and MCF-7 cells to Adriamycin via inhibiting the PI3K/AKT pathway. Overexpression of constitutively active AKT1 abolished the function of econazole. The combination of econazole and Adriamycin exerted synergistic inhibitory effects in breast cancer cells and . Taken together, the PI3K inhibitor econazole could effectively overcome Adriamycin resistance and showed synergistic effects with chemotherapy on breast cancer.

摘要

磷酸肌醇3激酶(PI3K)/AKT信号通路的激活常常与抗癌治疗耐药相关。PI3K抑制剂能够恢复对包括内分泌治疗、HER2靶向药物和化疗在内的标准乳腺癌治疗的敏感性。我们之前的研究表明,新型PI3Ka抑制剂益康唑可抑制PI3K/AKT信号通路并诱导肺癌细胞凋亡。在本研究中,益康唑对阿霉素耐药的乳腺癌细胞显示出显著的细胞毒活性。此外,益康唑通过抑制PI3K/AKT信号通路使MDA-MB-231和MCF-7细胞对阿霉素显著敏感。组成型活性AKT1的过表达消除了益康唑的作用。益康唑与阿霉素联合使用对乳腺癌细胞发挥协同抑制作用。综上所述,PI3K抑制剂益康唑可有效克服阿霉素耐药,并与化疗对乳腺癌显示出协同作用。
