A CRISPR study has determined how DNA times its own replication, something which until now has been unknown to scientists.
A modified version of CRISPR has been used to reverse genetic obesity in two different mouse models without editing any genes. The technique uses the guidance system in CRISPR to target certain genetic sequences and amplifies existing gene activity to ramp up protein production.
The CCR5 gene has been researched by scientists since the 1990s, and has a number of roles which have not yet properly been uncovered. Loss of the gene’s function is known, however, to increase the risk of potentially fatal reactions to some diseases, and has shown an ability to enhance learning in mice.
Scientists from the University of Pennsylvania have created a test using gene-editing tools such as CRISPR to identify a gene variant responsible for severe hypertrophic cardiomyopathy (SHC). SHC is an often-familial disease which thickens heart walls and is linked to a variant in the TNNT2 gene.
AstraZeneca and Cancer Research UK (CRUK) have announced that they will work together to open a new research centre in the UK, applying CRISPR and other functional genomics technologies to develop new cancer drugs. Specifically, the centre will study how genes and proteins interact with each other in cancer cells, and create disease models using genome-altering technologies based on this.
Baboons can live for up to 195 days with hearts taken from pigs and genetically engineered to avoid extreme immune reactions, three times longer than previous attempts, according to a report published in Nature journal.
The World Health Organization is establishing an expert panel to set guidelines and standards on the ethical and safety issues of gene editing, the body has announced. This follows the recent revelation that a scientist in China claimed he had edited the genes of twin babies to make them HIV resistant.
Twin girls in China have allegedly been born after having their embryonic genetic code modified using CRISPR. Chinese researcher He Jiankui, from the Southern University of Science and Technology, claims to have turned off a gene called CCR5 to offer total protection against HIV, as well as smallpox and cholera.
A new scientific innovation is set to help scientists understand the causes of cancer with greater speed and precision than ever before. Rather than looking at individual gene mutations on their own, scientists can now create models incorporating a number of mutations.
For the first time, scientists have performed prenatal gene editing to prevent a lethal metabolic disorder in laboratory animals, offering the potential to treat human congenital diseases before birth.
Researchers at the Key Laboratory of Synthetic Biology in Shanghai have used CRISPR to create a new species of yeast that only has a single giant chromosome.
To find out which DNA repair enzymes are critical to homology-directed repair after CRISPR cutting, researchers have knocked out, one at a time, more than 2,000 genes known or suspected to be involved in DNA repair, a function critical to a healthy cell.
