UW microbiologists discovered a bacterial toxin that, when engineered, is a key part of a gene editor that can make single-base changes in human mitochondria. The genome in mitochondria — the cell’s energy-producing organelles — is involved in disease and key biological functions, and the ability to precisely alter this DNA would allow scientists to...
by Bob Yirka , Medical Xpress A team of researchers working at Memorial Sloan Kettering Cancer Center in New York has discovered how metastatic cancer is able to survive in the hostile subarachnoid space. In their paper published in the journal Science, the group describes RNA sequencing studies they conducted with patients with leptomeningeal metastases...
An experimental drug for a rare, inherited form of amyotrophic lateral sclerosis has shown promise in a phase 1/phase 2 clinical trial, researchers report. The trial indicated that the experimental drug, known as tofersen, shows evidence of safety that warrants further investigation and lowers levels of a disease-causing protein in people with a type of...
MEDGADGET EDITORS GENETICS, NANOMEDICINE, OPHTHALMOLOGY Wet age-related macular degeneration and a number of other eye diseases, including congenital conditions, are related to mutated genes that result in blood vessel abnormalities. These can be treated with gene therapy, but delivering genetic material has proven to be difficult when dealing with large gene sequences that are common...
by University of Helsinki Activating the immune system is a promising form of cancer treatment. Researchers at the University of Helsinki and Helsinki University Hospital as well as the University of Eastern Finland mapped out the immune landscape of hematological malignancies in a dataset covering more than 10,000 patients to identify drug targets and patient...
Multiple forms of a non-functional, unfolded protein follow different pathways and timelines to reach its folded, functional state, a study reveals THE KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY (KAIST) THE SCIENTISTS FOUND THAT NON-FUNCTIONAL UNFOLDED FORMS OF THE PROTEIN CYTOCHROME C FOLLOW DIFFERENT PATHWAYS AND TIMELINES TO REACH A STABLE FUNCTIONAL FOLDED STATE. view...
by Children’s Hospital of Philadelphia A team of researchers from Children’s Hospital of Philadelphia (CHOP) used a new method of pinpointing potential disease-causing changes in the genome to identify two new potential therapeutic targets for lupus, while also paving the way for more accurately identifying disease-causing variations in other autoimmune disorders. The findings were published...

Findings could lead to new therapies for cancer, heart abnormalities UNIVERSITY OF COLORADO AT BOULDER Look deep inside our cells, and you’ll find that each has an identical genome -a complete set of genes that provides the instructions for our cells’ form and function. But if each blueprint is identical, why does an eye cell...
by Sheila Evans, University of Chicago Medical Center Many heritable immune diseases such as rheumatoid arthritis and blood-cell related traits derive from critical proteins not being made or not functioning correctly. But exactly how a person’s genes, the regulation of these genes and how the resulting proteins interact to cause disease is not widely understood....
