研究人员开发出一种新型结核病基因组组装工具
结核病 基因组 组装工具
2024/1/23
结核病（TB）是一种传染性疾病，也是全球范围内导致死亡的主要原因之一。结核分枝杆菌（MTB）是导致TB的细菌，据估计，2021年全球新发TB患者1060万人，并造成160万人死亡。近期，来自罗格斯大学与芝加哥大学等单位的研究团队，开发出一种新的基因组组装工具（Bact-Builder），并对MTB全球标准菌株H37Rv的参考基因组进行了全面更新。研究成果发表在《Nature Communicati...
Genetic engineering and personalized cell therapies could transform health care. In recent years, stem cells and gene-editing tools like CRISPR have been making headlines for the possibilities they of...
A seminal fluid protein transferred from male to female fruit flies during mating changes the expression of genes related to the fly’s circadian clock, an innovative technique has revealed.

It’s well-known that carrying one copy of the APOE4 gene variant increases one’s risk for Alzheimer’s disease threefold and two copies about tenfold, but the fundamental reasons why, and what can be d...
A team of scientists at the Whitehead Institute for Biomedical Research and the Broad Institute of MIT and Harvard has systematically evaluated the functions of over 5,000 essential human genes using ...
The liver’s ability to regenerate itself is legendary. Even if more than 70 percent of the organ is removed, the remaining tissue can regrow an entire new liver.
In recent years, scientists who study gene expression in cells have used a method that essentially pins a tail on RNA and tracks their whereabouts. However, certain types of RNA evade the process. Now...
