Genomic studies of cancer patients have revealed thousands of mutations linked to tumor development. However, for the vast majority of those mutations, researchers are unsure of how they contribute to...
Much of the human genome is made of regulatory regions that control which genes are expressed at a given time within a cell. Those regulatory elements can be located near a target gene or up to 2 mill...
Engineers at MIT and the University of Massachusetts Medical School have designed a new type of nanoparticle that can be administered to the lungs, where it can deliver messenger RNA encoding useful p...
Alzheimer’s risk gene undermines insulation of brain’s “wiring”（图）
阿尔茨海默氏症 风险基因 APOE4 脑细胞 隔离神经元
2023/6/21
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...
The Human Genome Project was an ambitious initiative to sequence every piece of human DNA. The project drew together collaborators from research institutions around the world, including MIT's Whitehea...
In human chromosomes, DNA is coated by proteins to form an exceedingly long beaded string. This “string” is folded into numerous loops, which are believed to help cells control gene expression and fac...
Despite the sheer number of genes that each human cell contains, these so-called “coding” DNA sequences comprise just 1 percent of our entire genome. The remaining 99 percent is made up of “non-coding...
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 ...
氯吡格雷是使用最广泛的P2Y12血小板抑制剂，然而，部分患者存在氯吡格雷抵抗。2020年美国心脏病学杂志（JACC）子刊发表了一项研究提出了ABCD-GENE评分量表的构建。ABCD-GENE评分量表纳入包括年龄、身体质量指数(BMI)、肾功能、糖尿病病史在内的临床因素和CYP2C19基因型，以更精确的识别氯吡格雷药效学反应较低的人群。
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.
New programmable gene editing proteins found outside of CRISPR systems（图）
CRISPR系统 可编程基因 编辑蛋白 酶
2023/6/20
Within the last decade, scientists have adapted CRISPR systems from microbes into gene editing technology, a precise and programmable system for modifying DNA. Now, scientists at MIT’s McGovern Instit...
New gene-editing technique shows promise against sickle cell disease（图）
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 ...
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 ...
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....
Study shows loss of gene function is causal to congenital heart disease（图）
loss of gene function causal congenital heart disease
2021/4/9
A team of researchers co-led by Michael Frohman of Stony Brook University has identified an important cause of congenital heart disease. The researchers discovered that certain loss of funct...
