DNA测序打破罕见遗传病诊断速度纪录
DNA测序 遗传病诊断
2022/1/28
美国斯坦福大学医学院科学家领导的联合团队开发的一种新的超快速基因组测序方法，可在平均8小时内诊断出罕见遗传疾病，这是标准临床护理领域中几乎闻所未闻的壮举。相关研究论文日前发表在《新英格兰医学杂志》上。
一项新研究挑战基因随机突变理论
基因随机突变
2022/1/28
长期以来，基因突变的随机性一直是生物演化理论的基础，然而这个生物学经典观点受到一项新研究的挑战。来自美国加利福尼亚大学戴维斯分校和德国马克斯·普朗克发育生物学研究所的研究人员日前在英国《自然》杂志上发表论文说，他们通过拟南芥实验发现，基因突变并非是随机的，而是以某种对植物有益的方式进行。这一新发现可能会从根本上改变人们对进化的理解，有望帮助科学家培育出更具优良性状的作物，甚至帮助人类开发对抗癌症等...
Ateam of researchers led by Harvard and Broad Institute scientists has developed twin prime editing, a new, CRISPR-based gene-editing strategy that enables manipulation of gene-sized chunks of DNA in ...

2021年11月17日，国际权威杂志《美国科学院院刊》（Proceedings of the National Academy of Sciences of the United States of America，PNAS）在线刊登了武汉大学信息管理学院青年教师黄颖副教授作为共同通讯作者的评论文章《迈向包容性的人类基因编辑全球治理》（Toward inclusive global governa...
Cut off the head of a three-banded panther worm, and it will grow another — mouth, brain, and all. Cut off its tail, and the same thing happens. Cut it in three pieces, and within eight weeks there’ll...
When Sharif Tabebordbar was a teenager, his father began having trouble walking. Soon, he became wheelchair-bound and was diagnosed with a rare genetic muscle disease.
The cost of DNA sequencing has plummeted at a rate faster than Moore’s Law, opening large markets in the sequencing space. Genomics for cancer care alone is predicted to hit $23 billion by 2025, but s...
Researchers at MIT’s McGovern Institute for Brain Research have discovered a bacterial enzyme that they say could expand scientists’ CRISPR toolkit, making it easy to cut and edit RNA with the kind of...

镰状细胞性贫血 基因编辑技术 一次性治疗
2023/6/21
Ateam of researchers led by scientists from Harvard and the Broad Institute used a new gene-editing technique to successfully treat sickle cell disease in mice. This advancement could one day lead to ...
哺乳动物细胞可将RNA序列写入DNA
哺乳动物细胞 RNA DNA
2021/6/16
美国费城托马斯杰斐逊大学的研究人员首次发现，哺乳动物细胞可以将RNA序列转换回DNA，这在病毒中比真核细胞更常见。这一发现可能会挑战生物学长期以来的观点，并可能对生物学的众多领域产生广泛影响。相关研究发表在6月11日的《科学进展》杂志上。
Elizabeth Kellogg, assistant professor of molecular biology and genetics in the College of Arts and Sciences, has been named to the Pew Scholars Program to pursue research into advancing gene editing ...
Gene editing, or purposefully changing a gene’s DNA sequence, is a powerful tool for studying how mutations cause disease, and for making changes in an individual’s DNA for therapeutic purposes. A nov...
《细胞》杂志9日在线发表的一篇论文表示，美国怀特黑德研究所乔纳森·魏斯曼等人设计了一种名为CRISPRoff的新基因编辑技术，可以在不改变DNA序列的情况下使某些基因“沉默”，从而以高特异性控制基因表达。这种“升级版”的基因编辑技术为研究表观遗传机制、重大疾病治疗以及研发新冠病毒疫苗等提供了有力工具。
Over evolutionary time scales, a single gene may acquire different roles in diverging species. However, revealing the multiple hidden roles of a gene was not possible before genome editing came along....
