Abstract

Chromosomal aberrations, including aneuploidies and structural rearrangements, are key drivers of cancer and numerous genetic disorders. Experimental modeling of these alterations is essential for understanding their role in disease initiation and progression. Historically, chromosome engineering relied on methods that lacked precision and could generate off-target genomic damage. Recent advances in genome editing have enabled the precise generation of defined chromosomal abnormalities in human cells. This review summarizes current approaches for modeling numerical and structural chromosomal aberrations, including CRISPR-based chromosome elimination, KaryoCreate, prime editing, programmable recombinases, and RNA-guided bridge recombinases. We also discuss strategies for generating complex chromosomal rearrangements, their applications in studying genome instability, and their limitations. Together, these technologies provide powerful tools to investigate the earliest genomic events underlying cancer and genetic diseases.

染色体畸变模型再现基因组重排的研究进展。
染色体畸变,包括非整倍体和结构重排,是癌症和许多遗传疾病的关键驱动因素。这些改变的实验建模对于理解它们在疾病发生和发展中的作用是必不可少的。从历史上看,染色体工程依赖的方法缺乏精度,可能会产生脱靶的基因组损伤。基因组编辑的最新进展使人类细胞中明确的染色体异常的精确产生成为可能。本文综述了目前用于模拟数值和结构染色体畸变的方法,包括基于crispr的染色体消除、核创建、引物编辑、可编程重组酶和rna引导桥接重组酶。我们还讨论了产生复杂染色体重排的策略,它们在研究基因组不稳定性中的应用,以及它们的局限性。总之,这些技术为研究癌症和遗传疾病的早期基因组事件提供了强有力的工具。

期刊介绍: Trends in Molecular Medicine (TMM) aims to offer concise and contextualized perspectives on the latest research advancing biomedical science toward better diagnosis, treatment, and prevention of human diseases. It focuses on research at the intersection of basic biology and clinical research, covering new concepts in human biology and pathology with clear implications for diagnostics and therapy. TMM reviews bridge the gap between bench and bedside, discussing research from preclinical studies to patient-enrolled trials. The major themes include disease mechanisms, tools and technologies, diagnostics, and therapeutics, with a preference for articles relevant to multiple themes. TMM serves as a platform for discussion, pushing traditional boundaries and fostering collaboration between scientists and clinicians. The journal seeks to publish provocative and authoritative articles that are also accessible to a broad audience, inspiring new directions in molecular medicine to enhance human health.
