A team of researchers at the Broad Institute of MIT and Harvard has engineered virus-like particles to deliver prime editors to cells in mice at a high enough efficiency to rescue a genetic disorder. They also delivered prime editors to the mouse brain, and did not detect any off-target editing.
gget ( [link] ) is a free, open-source command-line tool and Python package designed to enable efficient querying of large genomic databases, such as Ensembl, UniProt, and NCBI. Joe is a fourth-year USC-Caltech MD-PhD student in the Pachter Lab, and he is working on a novel algorithm to detect carcinogenic variants in RNA sequencing data.

This engineered capsid opens up a world of possibilities."
To deliver CHARM throughout the brain, the team collaborated with scientists in the lab of Ben Deverman , senior director of vector engineering at the Broad and a co-author of the study. They used an engineered adeno-associated virus (AAV) that crosses the blood-brain barrier after intravenous administration. Online June 27, 2024.
The molecular machinery of the epigenetic system can selectively package specific regions of DNA away, making them inaccessible and less active. This platform opens the door to treating complex multigenic diseases, effective tissue engineering, and fine-tuning immune cell differentiation. Molecular Therapy. 2021;29(9):2640–59.
The other study was led by senior authors Xiao Wang , a Broad core institute member, a Merkin Institute Fellow, and an assistant professor of chemistry at MIT, and Jia Liu, an assistant professor of engineering at Harvard University.

Codon Digest is my weekly roundup of research, news, and industry highlights about engineered biology. An engineered version of this protein can convert DNA bases with efficiencies up to 92%. A particular variant, named IscB*-ωRNA*, had the highest editing efficiency across multiple different sites in the genome.

The company’s product candidates consist of novel human cells engineered to produce the crucial proteins, enzymes or factors needed by patients living with chronic diseases such as hemophilia, diabetes and lysosomal storage disorders. Laying down a new track for RNA processing, Remix launched with $81 million in financing.
In the first real test of delivering a complex biomolecule to over a billion people, little has changed from how Genentech first approached manufacturing in the 1980s; Cells are genetically engineered and then grown in steel tanks. But this isn’t a problem with extracts.
What are the key findings of Circio’s in vivo proof-of-concept for its circVec circular RNA platform technology compared to conventional mRNA-based expression with DNA vectors? Circular RNA (circRNA) has two major advantages versus mRNA in a vector-expression context.
But for a recent paper out of Nanjing, China, researchers engineered another enzyme and showed that, when mixed with FAST-PETase, the two worked together to break down plastic twice as fast as the Texas enzyme alone. Because it turns out that at least half of them , in humans, also bind to RNA molecules. RNA export systems.

A gene encoding green fluorescent protein was placed alongside one of the three promoters, and as the engineered cells cycled from one gene to the next, they blinked between green—dark—green—dark. The RNA Exporter , which was developed by Felix Horns and others in my lab, is one example. Elowitz: It’s a mix.
It received FDA guidance January 5 th and is in the midst of preparing the first package of investigational new drug (IND) applications – usually with an n-of-1, for individual patients. That’s not the case with RNA-targeted drugs. Working closely with Ionis, “We connect the need to the drug development engine.
I’m writing long essays for Asimov every other week and my work at MIT, where I’m helping to design a genetic engineering curriculum for undergraduates, has reached its crescendo. Anyone who has tried to engineer a cell knows how tedious it can be. And it’s been my life for the last few weeks. A Mycoplasma cell.

The company confirmed the tirzepatide SURPASS program has met global regulatory submission requirements for evaluating cardiovascular risk and its intention to submit the registration package to regulatory authorities by the end of 2021. The company announced the acquisition of Protomer Technologies Inc.,
tuberculosis known as rpoB , which codes for part of its RNA polymerase. Engineers at Khon Kaen University in Thailand are developing one such technique based on Raman scattering , a phenomenon in which compounds excited with one wavelength of light emit photons in a different part of the electromagnetic spectrum.
Most people would take the two CRISPR gene-editing components (a Cas9 protein and guide RNA), package them up inside of a virus, and then inject the viruses into the skulls of mice. Genetic engineering can be used to eradicate mosquitoes in two ways: Through gene drives or the “sterile insect technique.” Stahl et al.

Scientists are already building a model that can, for example, look at which RNA molecules are expressed in a cell at t=0 and predict how those molecules will change at t=1. SeqFISH, developed by Long Cai’s group at Caltech, maps the spatial positions of thousands of RNA, DNA, or protein molecules within single cells.
