Researchers at The University of Texas MD Anderson Cancer Center have identified a specific protein, RASH3D19, that is responsible for activation of RAS signaling pathways involved in aggressive tumor growth and resistance to KRAS inhibitors in patients with KRAS-mutant cancers. Blocking RASH3D19 in combination with KRAS inhibitors improved outcomes in preclinical models, suggesting this combination as a potential therapeutic strategy for patients with KRAS-mutant cancers.

Cedars-Sinai scientists have developed an experimental drug that repairs DNA and serves as a prototype for a new class of medications that fix tissue damage caused by heart attack, inflammatory disease or other conditions.

Investigators describe the workings of the drug, called TY1, in a paper published in Science Translational Medicine.

Finland was the first country to offer the zoonotic avian influenza A(H5N8) vaccine manufactured by Seqirus to at-risk occupational groups following the extensive clade 2.3.4.4b A(H5N1) outbreak affecting wild birds and fur farms in Finland in 2023.

A new study published in Nature Microbiology shows that the MF59-adjuvanted A(H5N8) vaccine induced strong immune responses, including both functional antibodies and memory T-cell responses,

The human P2X4 receptor plays an important role in chronic pain, inflammation and some types of cancer. Researchers at the University of Bonn and the University Hospital Bonn (UKB) have now discovered a mechanism that can inhibit this receptor. The results were recently published in the scientific journal Nature Communications and open up a pathway for the development of new drugs.

After a spinal cord injury, cells in the brain and spinal cord change to cope with stress and repair tissue. A new study from Karolinska Institutet, published in Nature Neuroscience, shows that this response is controlled by specific DNA sequences. This knowledge could help develop more targeted treatments.

When the central nervous system is damaged - for example, in a spinal cord injury - many cells become reactive.

Protein kinases are the molecular switches of the cell. They control growth, division, communication, and survival by attaching phosphate groups to other proteins. When these switches are stuck in the "on" position, they can drive cancer and other diseases. Not surprisingly, kinases have become one of the most important drug target families in modern medicine: today, more than 80 kinase inhibitors are FDA-approved, and nearly twice as many are in clinical development.

Researchers at the Icahn School of Medicine at Mount Sinai and collaborators have reported early success with a novel mRNA-based therapy designed to combat antibiotic-resistant bacteria.

The findings, published in the November 26 online issue of Nature Biotechnology, show that in preclinical studies in mice and human lung tissue in the lab, the therapy slowed bacterial growth, strengthened immune cell activity, and reduced lung tissue damage in models of multidrug-resistant pneumonia.
