Proto-oncogene Vav (VAV1) is a guanine exchange factor that is crucial for T- and B-cell receptor signaling. Assays in Vav1-knockout murine models had previously demonstrated diminished effector functions and resistance to autoimmune disease. Monte Rosa Therapeutics AG has presented data on the VAV1 inhibitor MRT-6160, a first-in-class molecule that targets VAV1 for proteasomal degradation, thought to potentially treat autoimmune diseases through the degradation of VAV1.

Investigators from the Chinese Academy of Medical Sciences & Peking Union Medical College presented data from a study that investigated the regulatory mechanisms of intestinal epithelial cell (IEC) death and intestinal inflammation.

Infection with Helicobacter pylori is a risk factor for the development of gastric cancer. H. pylori initiates a chronic inflammatory response that can lead to the production of excessive radical oxygen species (ROS), which in turn can activate oncogenic signaling pathways leading to gastric cancer development. SUMOylation is a post-translational modification mechanism in cells in response to reactions to stress. A team at The First Affiliated Hospital of Nanchang University hence set out to study the role of SUMO-activating enzyme subunit 1 (SAE1) in gastric cancer, since it is a SUMO-activating effector protein.

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease (NAFLD), is characterized by accumulation of triglycerides (TGs) in liver hepatocytes, and which can progress into chronic liver disease or even hepatocellular carcinoma.

Attovia Therapeutics Inc. has announced the closing of the $30 million second tranche of its $60 million series A financing.

Kupffer cells are macrophages located in the liver that play a key role in liver pathology, concretely in metabolic dysfunction-associated steatotic liver disease (MASLD; formerly nonalcoholic fatty liver disease or NAFLD), but the mechanisms behind this are poorly understood.
