非洲猪瘟是由ASFV引起的猪烈性传染病，具有高致死率，自2018年传入我国以来，已造成巨大经济损失，严重威胁全球养猪业安全。由于ASFV基因组庞大复杂，编码蛋白众多，且缺乏有效抗病毒药物和商业化疫苗，其防控一直是全球兽医领域的重大难题。病毒DNA聚合酶作为基因组复制的核心“引擎”，是抗病毒药物开发的关键靶点，但ASFV的DNA聚合酶的复制机制此前尚未被完全解析。

Non-coding DNA is essential for both humans and trypanosomes, despite the large evolutionary divergence between these two species.

DNA replication is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

引言在细胞每一次分裂、每一次应对内外环境挑战的喧嚣中，我们的基因组(genome)正经历着持续的修订、涂抹甚至撕裂。在癌症和许多先天性疾病的基因组中，我们常常能看到一些令人匪夷所思的混乱景象：染色体片段的诡异扩增、莫名其妙的序列插入、以及如同地震后断 ...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

The herpesvirus can manipulate our DNA with far more precision than previously thought. The virus condenses and changes the shape of our genetic material to hijack the host genes needed for ...

Researchers at The Institute of Cancer Research, London identified the CIP2A–TOPBP1 complex as a master regulator of DNA repair during mitosis, coordinating backup pathways that protect chromosomes ...

A new LUMC study has changed our understanding of how cells work. Researchers have discovered that the CFAP20 protein acts as ...

Cancer researchers at the University of Chicago and the University of California, San Francisco (UCSF) have discovered that mutations in certain genes can lead to the accumulation of DNA errors, ...
