Using CRISPR, New Technique Makes It Easy to Map Genetic Networks

Scientists have developed an easy way to genetically profile a cell, including human cells, and rapidly determine all DNA sequences in the genome that regulate expression of a specific gene. This can ...

HIV-Like Virus Edited out of Primate Genome

Taking a major step forward in HIV research, scientists have successfully edited SIV - a virus closely related to HIV, the cause of AIDS - from the genomes of non-human ...

New Insights Into How the CRISPR Immune System Evolved

Although CRISPR-Cas has found many uses in biotechnology and medicine, it originates in nature, where it functions as a microbial immune system. Scientists shed new light on how CRISPR-Cas emerged ...

CRISPR Meets Pac-Man: New DNA Cut-and-Paste Tool Enables Bigger Gene Edits

Gene editing for the development of new treatments, and for studying disease as well as normal function in humans and other organisms, may advance more quickly with a new tool for cutting larger ...

'Off Switch' During Error-Prone Cell Cycle Phase May Fix CRISPR's Unwanted Changes Problem

Turning off gene-editing until it reaches cell cycle phases where more accurate repairs are likely to happen offers a promising fix to CRISPR-Cas9's problem with unwanted genetic ...

Advancing Gene Editing With New CRISPR/Cas9 Variant

Researchers report the ability to improve safety and efficacy using a CRISPR-Cas9 variant known as ...

CRISPR Tagging Improves Accuracy of Model Cells Grown from Stem Cells

CRISPR tags are being used to identify all of the transcription factors necessary to turn a pluripotent stem cell into a suitable adult cell for research, and possible future cell therapies. An ...

Researchers Pioneer More Effective Way to Block Malaria Transmission in Mosquitoes

Employing a strategy known as 'population modification,' which involves using a CRISPR-Cas9 gene drive system to introduce genes preventing parasite transmission into mosquito chromosomes, ...

'BAH-Code' Reader Senses Gene-Silencing Tag in Cells

Researchers have identified an evolutionarily conserved pathway responsible for 'closing down' gene activity in the mammalian cell. The finding is closely related to the Polycomb pathway ...

Quality Control Mechanism Closes the Protein Production 'on-Ramps'

Recent work revealed a newfound quality control system in the protein production assembly line with possible implications for understanding neurogenerative ...

Biologists Create New Genetic Systems to Neutralize Gene Drives

Addressing concerns about gene drive releases in the wild, scientists have developed two new genetic systems that halt or eliminate gene drives after release. Created in fruit flies, the e-CHACRs and ...

Research Shows Potential of Gene Editing in Barley

An international team of plant scientists have shown the potential to rapidly improve the quality of barley grain through a genetic tool known as CRISPR or gene ...

Scientists Identify Gene Family Key to Unlocking Vertebrate Evolution

New research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an important episode ...

Diamondback Moth Uses Plant Defense Substances as Oviposition Cues

Researchers showed that isothiocyanates produced by cruciferous plants to fend off pests serve as oviposition cues. The scientists identified two olfactory receptors whose sole function is to detect ...

Through Enzyme Testing, Researchers Sharpen CRISPR Gene-Editing Tool

One of the biggest scientific advances of the last decade is getting better. A team has developed a new tool to help scientists choose the best available gene-editing option for a given job, making ...

Inheritance in Plants Can Now Be Controlled Specifically

A new application of the CRISPR/Cas molecular scissors promises progress in crop cultivation. Researchers have succeeded in modifying the sequence of genes on a chromosome using CRISPR/Cas. For the ...

Scientists Use CRISPR to Knock Down Gene Messages Early in Development

Researchers have harnessed the technology to target gene messages (messenger RNA) involved in early vertebrate ...

First Gene Knockout in a Cephalopod Achieved

Biologists have achieved the first gene knockout in a cephalopod using the squid Doryteuthis pealeii, an exceptionally important research organism in biology for nearly a century. The team used ...

New Understanding of CRISPR-Cas9 Tool Could Improve Gene Editing

Of the CRISPR-Cas9 tools created to date, base editors have gotten lots of attention because of their seemingly simple editing: they neatly replace one nucleic acid with another, in many cases all ...

Researchers Map Mechanisms in the Largest CRISPR System

The largest and most complex CRISPR system has been visualized by researchers in a new study. The system may have potential applications in biomedicine and biotechnology, the researchers ...

New CRISPR C-to-G DNA Base Editor Expands the Landscape of Precision Genome Editing

The new base editing platform may help researchers understand and correct genetic diseases by selective editing of single DNA 'letters' across nucleobase ...

Site-Directed Mutagenesis in Wheat Via Haploid Induction by Maize

Site-directed mutagenesis facilitates the experimental validation of gene function and can speed up plant breeding by producing new biodiversity or by reproducing previously known gene variants in ...

Megaphages Harbor Mini-Cas Proteins Ideal for Gene Editing

Cas proteins like CRISPR-Cas9 have great potential for gene therapy to treat human disease and for altering crop genes, but the gene-targeting and gene-cutting Cas proteins are often large and hard ...

Safer CRISPR Gene Editing With Fewer Off-Target Hits

The CRISPR system is a powerful tool for the targeted editing of genomes, with significant therapeutic potential, but runs the risk of inappropriately editing ''off-target'' ...
