Genome Editing Procedures Optimised

Scientists succeed in boosting the efficiency of CRISPR/Cas9 and related methods and modifying initially inaccessible DNA sequences


In the course of optimising key procedures of genome editing, researchers from the department of Developmental Biology / Physiology at the Centre for Organismal Studies of Heidelberg University have succeeded in substantially improving the efficiency of molecular genetic methods such as ...

New insights into the genetic basis of leukemia

Research team discovers links between certain gene mutation and the spatial structure of DNA in blood cancer at an advanced age


Acute myeloid leukemia (AML) is a malignant disease of the haematopoietic system that originates from immature precursors of red blood cells, platelets and part of the white blood cells. While in healthy people the multiplication and renewal of blood cells is strictly regulated this process gets ...

AI improves colorectal cancer screening in Lynch syndrome

Increase adenoma detection rate


First study of AI-assisted colonoscopy for colorectal cancer surveillance in patients with genetic predisposition - People with Lynch syndrome have a higher hereditary risk of colon cancer. Despite regular endoscopic surveillance, it remains elevated in those affected. Researchers at the National ...

EditForce Realizes RNA-editing Technology of "U-to-C"

Possibility to edit mutations which could not have been the target with the existing technologies


EditForce, Inc.,a Kyushu University-originated venture company headquartered in Fukuoka, Japan, has realized the world's first RNA-editing technology that enables RNA-editing bases to be changed from "U" to "C," and demonstrated that this technology works even in human cells in a joint study ...

Keeping aggressive cancer cells in check

An astonishing observation


BRCA1/2-mutated tumor cells often survive treatment, whether it’s chemo- or radiotherapy, because they can repair therapy-induced DNA damage. A team led by Claus Scheidereit of the Max Delbrück Center has now reported in The EMBO Journal how blocking the TSG101 protein hinders these tumor cells ...

Longer life due to faulty RNA processing

If introns remain in certain RNAs, worms live longer


The control of RNA metabolism is crucial to the regulation of animal longevity, researchers from the Max Planck Institute for Biology of Ageing in Cologne have now discovered. They found that worms live longer when certain RNAs are processed differently during RNA maturation. This could be an ...

Genetic Testing Before Pregnancy Detects up to Half of the Risk

Are would-be parents carrying a genetic risk of serious illnesses that they could potentially pass on to their children?


In the USA, doctors recommend that couples have genetic screening before trying to conceive. Researchers at the University of Zurich have now shown that a maximal variant of this test detects the risk in 44 percent of couples who are related by blood, and in just 5 percent of other couples. ...

New genes with mutations for developmental disorders identified

Tracking down the causes of rare diseases in children


The causes of intelligence impairment or epilepsy remain unexplained in more than 50 per cent of cases. Together with international colleagues, researchers at Leipzig University Hospital have discovered two genes with mutations that cause neurodevelopmental disorders in children. Their findings ...

Rare discovery: How a gene mutation causes higher intelligence

“It’s very rare for a mutation to lead to improvement rather than loss of function”


When genes mutate, this can lead to severe diseases of the human nervous system. Researchers at Leipzig University and the University of Würzburg have now used fruit flies to demonstrate how, apart from the negative effect, the mutation of a neuronal gene can have a positive effect – namely ...

Study help to pinpoint cancer culprits

Largest study of whole genome sequencing data reveals ‘treasure trove’ of clues about causes of cancer


DNA analysis of thousands of tumours from NHS patients has found a ‘treasure trove’ of clues about the causes of cancer, with genetic mutations providing a personal history of the damage and repair processes each patient has been through. In the biggest study of its kind, a team of scientists led ...
