New Protein Could Deliver Next Gene-Editing Tool
While CRISPR Cas9 remains a mainstay in the genomics world, researchers have now found a much smaller protein called CasX that could be used for gene editing. In 2017, a research team from the University of California Berkeley discovered in some of the world’s smallest bacteria a protein similar to Cas9 but substantially smaller, which…
In Prenatal Testing, ‘Genomics’ Sometimes Sees What Genetic Tests Can’t
New Mutations Causing Inherited Deaf-Blindness Have Been Discovered
A team of scientists from Sechenov First Moscow State Medical University (MSMU) together with their colleagues from leading scientific centers of Moscow and India described a number of genetic mutations causing Usher syndrome (inherited deaf-blindness). They found previously unstudied unique mutations in investigated DNA regions. The results of the study were published in the Ophthalmic Geneticsjournal.…

Orchard Therapeutics to Build New Gene Therapy Manufacturing Facility in California
CRISPR Method for Conditional Gene Regulation
A team of engineers at the University of Delaware has developed a method to use CRISPR/Cas9 technology to set off a cascade of activities in cells, a phenomenon known as conditional gene regulation. Their method, described in the journal Nature Chemical Biology, introduces a new functionality to CRISPR, one of today’s most-talked-about technologies. Gene editing…
CRISPR Gene Editing Will Find Applications in Plastic and Reconstructive Surgery
Breakthrough: Promising New Genetic Target for Immunotherapy
Following the 2018 Nobel Prize for Medicine, global attention is now more than ever turned toward the promise of immunotherapy in oncology. An international team’s work has shed new light on a molecule called TIM-3 that might play a key role in the regulation of the immune response. Scientists and physicians from the Research Institute…
Novel Combination Therapy Promotes Wound Healing
By incorporating a gene-suppressing drug into an over-the-counter gel, researchers at Albert Einstein College of Medicine and their colleagues cut healing time by half and significantly improved healing outcomes compared to control treatments. Results from the combination therapy, which was tested in mice, were published online today in Advances in Wound Care. “Not only did wound…
New CRISPR Tool Opens Up More of the Genome for Editing
The genome editing system CRISPR has become a hugely important tool in medical research, and could ultimately have a significant impact in fields such as agriculture, bioenergy, and food security. The targeting system can travel to different points on the genome, guided by a short sequence of RNA, where a DNA-cutting enzyme known as Cas9 then…
Novel DNA Vaccine Design Offers Broad Protection Against Influenza-A H3N2
Researchers Modify CRISPR to Reorganize Genome
Researchers at Stanford University have reworked CRISPR-Cas9 gene-editing technology to manipulate the genome in three-dimensional space, allowing them to ferry genetic snippets to different locations in a cell’s nucleus. The new technique, dubbed CRISPR-genome organization or simply CRISPR-GO, uses a modified CRISPR protein to reorganize the genome in three dimensions. If CRISPR is like molecular…

Molecular Hopper Can Move Individual DNA Strands
A research team from the University of Oxford has developed a molecular hopper that is small enough to be able to move single strands of DNA through a protein nanotube. The device works by making and breaking in sequence simple chemical bonds that attach it to a nanoscale track that can be turned on, off…
CRISPR Halts Duchenne Muscular Dystrophy Progression in Dogs
Scientists for the first time have used CRISPR gene editing to halt the progression of Duchenne muscular dystrophy (DMD) in a large mammal, according to a study by UT Southwestern that provides a strong indication that a lifesaving treatment may be in the pipeline. The research published in Science documents unprecedented improvement in the muscle…
Predicting How Splicing Errors Impact Disease Risk
No one knows how many times in a day, or even an hour, the trillions of cells in our body need to make proteins. But we do know that it’s going on all the time, on a massive scale. We also know that every time this happens, an editing process takes place in the cell…
