The vast variety of tumors makes each cancer a world. For researchers, understanding the commonalities and divergences in their molecular underpinnings could help find successful treatments. Scientists from the Clinical Proteomic Tumor Analysis Consortium (CPTAC) have addressed these similarities and differences in 10 different types of cancer with two proteogenomic studies to unravel the genes that lead to cancer and the galaxy of interactions that regulate them.

Scientists have discovered that a small chemokine protein released by activated platelets, platelet factor 4 (PF 4), reduced neuroinflammation, and improved cognition in aged mice. The study was published on Aug. 16 in the online edition of Nature.

In brain research, be it basic or clinical, neurons have long hogged the limelight. But at the 2023 European Meeting on Glial Cells in Health and Disease, neurons take a back seat to glia – cell types that have often been described as support cells and treated as an afterthought, but that play critical roles in all aspects of brain function, including information processing.

At the 2023 Annual Congress of the European Academy of Neurology, Mary Reilly described the relationship between bench and bedside as “a continuous circle of translation,” with each cycle beginning with patients and their needs.

Artificial intelligence (AI) continues to entice. On the exhibition floor at the 2023 Congress of the European Academy of Neurology, one company’s booth featured “Mindart” technology. A passersby could answer a short series of prompts, and get a unique image based on the input made by generative AI. Entertainment aside, medically speaking, AI applications “are still research,” Riccardo Soffietti told his audience at one of several sessions devoted to AI. “But obviously, research is the future.”

The development of an embryo in its early stages involves a series of processes in which cells interact and organize to form tissues. In humans, these stages are studied with animal models, stem cells and cell aggregates that mimic natural development phases, or with human embryos, depending on their availability and a strict protocol. Now, in back-to-back papers published online in Nature, scientists from Yale University and the University of Cambridge have two new embryonic models formed from human stem cells to study development after embryo implantation in the uterus.

Back-to-back papers in the June 22, 2023, issue of Nature have identified separate molecular mechanisms underlying sex-specific cancer outcomes. Researchers from The University of Texas MD Anderson Cancer Center showed that increased expression of the epigenetic enzyme KDM5D, which is located on the Y chromosome, contributed to cancer progression in KRAS-mutated tumors. In the same issue of Nature, a team from Cedars-Sinai reported new insights into the consequences of losing the entire Y chromosome.

Barring truly major surprises, exagamglogene autotemcel (Exa-cel, Vertex Pharmaceuticals Inc.) is on track to become the first approved CRISPR-based gene editing therapy. It is partly in expectation of Exa-cel’s approval that the European Hematology Association (EHA) and the European Society for Bone Marrow Transplantation hosted a session on “transplantation versus gene therapy in sickle cell disease.”
