FAM83B 可调节肺腺癌的线粒体代谢和抗凋亡活性。
化疗是一种有效的治疗方式;然而,相当一部分确诊为肺腺癌(LUAD)的患者对化疗产生了耐药性。因此,了解潜在的调控机制对开发新型治疗策略至关重要。本研究旨在了解 FAM83B 表达的增加如何影响线粒体活性、细胞凋亡以及 LUAD 的化疗效果。研究采用了多种检测方法,如CCK8、伤口愈合、EdU和透孔检测等,以证实FAM83B过表达会导致LUAD细胞的化疗耐药性增强、细胞增殖、迁移和侵袭能力增强。此外,还利用 MIMP、MTG 和 ATP 检测来量化线粒体代谢的变化。体外功能测试评估了 FAM83B 过表达对 LUAD 恶性进展和化疗耐药机制的影响。研究发现,FAM83B表达增加的LUAD患者存活时间较短,与原发样本相比,FAM83B过表达的组织样本更容易发生转移。因此,FAM83B 被认为是一个不利预后的标志物。机理分析表明,FAM83B 阻碍了钙宾蛋白 2(CALB2)从细胞质到线粒体的转位,从而抑制了细胞凋亡,促进了线粒体活性。因此,这最终赋予了 LUAD 对化疗的抵抗力。此外,服用二甲双胍可阻断线粒体氧化磷酸化(OXPHOS),从而恢复 LUAD 对耐药性的敏感性。综上所述,这些发现提供了大量证据,支持 FAM83B 通过上调线粒体代谢和抑制细胞凋亡增强 LUAD 化疗耐药性的观点。

期刊介绍: Apoptosis, a monthly international peer-reviewed journal, focuses on the rapid publication of innovative investigations into programmed cell death. The journal aims to stimulate research on the mechanisms and role of apoptosis in various human diseases, such as cancer, autoimmune disease, viral infection, AIDS, cardiovascular disease, neurodegenerative disorders, osteoporosis, and aging. The Editor-In-Chief acknowledges the importance of advancing clinical therapies for apoptosis-related diseases. Apoptosis considers Original Articles, Reviews, Short Communications, Letters to the Editor, and Book Reviews for publication.
