Cancer therapies can eliminate specific tumors based on their genetic content. However, some cancer cells survive. How do they do it? Part of the answer lies in extrachromosomal DNA (ecDNA), an ace up the tumors’ sleeve to adapt and evade attack. Three simultaneous studies in the journal Nature lay all the cards on the table, revealing ecDNAs’ content, their origin, their inheritance, their influence in cancer, and a way to combat them.
Reducing microglial activity in the presence of apolipoprotein E4 (APOE4) has uncovered a mechanism associated with the deposition of misfolded amyloid and tau in a novel mouse model of Alzheimer’s disease. By transplanting human neurons into the mouse brain and eliminating the mouse microglia, scientists at the Gladstone Institutes in San Francisco observed that amyloid and tau deposition was reduced. These results support therapeutic strategies that target APOE4 and microglia.
Gene editing strategies, from epigenetic engineering to cell reprogramming and genetic vaccines, are accelerating the development of new therapies that awaken the immune system to treat cancer, as presented last month in Rome at the 31st Annual Congress of the European Society of Gene and Cell Therapy (ESGCT). Some of these advances are taking advantage of the conditions of the tumor microenvironment, where cancer cells coexist with immune cells, microorganisms and blood vessels.
Scientists from different laboratories around the world have presented the latest advances in research into malignant brain tumors at the 31st Annual Congress of the European Society of Gene and Cell Therapy (ESGCT), which is being held Oct. 22 to 25 in Rome.
Some rare skin diseases not only reduce the quality of life of patients, but also can be devastating conditions, leading to amputations or death. At the 31st annual congress of the European Society of Gene and Cell Therapy (ESGCT), held last week in Rome, different laboratories showcased their approaches to editing mutations related to this group of diseases.

Repeated RNA elements have a virus-like behavior in the cells that express them. Furthermore, they could confer a novel mode of tumor expansion based on changes in cellular states. “About 10 years ago, we had identified that these repetitive elements were highly expressed in pancreas cancer,” co-senior author David Ting, associate professor of medicine and assistant physician at the Mass General Cancer Center at Harvard Medical School, told BioWorld.
David Baker, Demis Hassabis and John Jumper share the 2024 Nobel Prize in Chemistry for their contributions to the science of protein structure. David Baker was awarded half the prize “for computational protein design,” according to the Royal Swedish Academy of Sciences. Hassabis and Jumper shared the other half “for protein structure prediction.”
To recreate in the laboratory the formation of Lewy bodies as they would occur in a Parkinson’s patient, two ingredients are required: the protein α-synuclein and the participation of the immune system. The results could prevent the development and progression of this neurodegenerative disorder and help in the search for new therapies.
