摘要

摘要：在本期《血癌发现》（Blood Cancer Discovery）杂志上，Nakanishi等人发现了翻译起始因子eIF5A活性升高在MYC驱动的淋巴瘤恶性生长中的关键作用。eIF5A通过MYC肿瘤蛋白介导的多胺-羽扇豆碱环路的过度激活进行翻译后修饰，这可能是一个很有前景的治疗靶点，因为事实证明，该环路中的一种酶对eIF5A的过度修饰是淋巴瘤发展所必需的。参见 Nakanishi 等人的相关文章，第 294 页（4）。

An MYC-Driven Vicious Circuit Is a Targetable Achilles' Heel in Lymphoma.

Summary: In this issue of Blood Cancer Discovery, Nakanishi et al. uncover a critical role for the elevated activity of the translation initiation factor eIF5A in the malignant growth of MYC-driven lymphoma. eIF5A is posttranslationally modified by hypusination through MYC oncoprotein-mediated hyperactivation of the polyamine-hypusine circuit, which may represent a promising therapeutic target because an enzyme of this circuit that is required for hypusinating eIF5A proved to be essential for lymphoma development.

期刊介绍： The journal Blood Cancer Discovery publishes high-quality Research Articles and Briefs that focus on major advances in basic, translational, and clinical research of leukemia, lymphoma, myeloma, and associated diseases. The topics covered include molecular and cellular features of pathogenesis, therapy response and relapse, transcriptional circuits, stem cells, differentiation, microenvironment, metabolism, immunity, mutagenesis, and clonal evolution. These subjects are investigated in both animal disease models and high-dimensional clinical data landscapes. The journal also welcomes submissions on new pharmacological, biological, and living cell therapies, as well as new diagnostic tools. They are interested in prognostic, diagnostic, and pharmacodynamic biomarkers, and computational and machine learning approaches to personalized medicine. The scope of submissions ranges from preclinical proof of concept to clinical trials and real-world evidence. Blood Cancer Discovery serves as a forum for diverse ideas that shape future research directions in hematooncology. In addition to Research Articles and Briefs, the journal also publishes Reviews, Perspectives, and Commentaries on topics of broad interest in the field.
