Researchers discover a new function of CRISPR/Cas9 gene scissors

For several years now, the CRISPR/Cas9 gene scissors have been causing a sensation in science and medicine. This new tool of molecular biology has its origins in an ancient bacterial immune system. It protects bacteria from attack by so-called phages, ie viruses that infect bacteria. Researchers from the Institute of Structural Biology at the University … Read more

Novel gene editing therapy reduces circulating TTR protein levels in patients with ATTR amyloid cardiomyopathy

A single IV infusion of NTLA-2001, a novel CRISPR/Cas9-based gene editing therapy, significantly reduced circulating transthyretin (TTR) protein levels in patients with ATTR amyloid fatal cardiomyopathy, a progressive and cause of heart failure, according to late-breaking research presented today at the American Heart Association’s Scientific Sessions 2022. The meeting, held in person in Chicago and … Read more

New control system could be used to finely tune the production of useful proteins

Using an approach based on CRISPR proteins, MIT researchers have developed a new way to precisely control the amount of a particular protein that is produced in mammalian cells. This technique could be used to finely tune the production of useful proteins, such as the monoclonal antibodies used to treat cancer and other diseases, or … Read more

One of the Biggest Problems in Biology Has Finally Been Solved

There’s an age-old adage in biology: structure determines function. In order to understand the function of the myriad proteins that perform vital jobs in a healthy body—or malfunction in a diseased one—scientists have to first determine these proteins’ molecular structure. But this is no easy feat: protein molecules consist of long, twisty chains of up … Read more

A “door” into the mitochondrial membrane | MIT News

Mitochondria — the organelles responsible for energy production in human cells — were once free-living organisms that found their way into early eukaryotic cells over a billion years ago. Since then, they have merged seamlessly with their hosts in a classic example of symbiotic evolution, and now rely on many proteins made in their host … Read more
