From shift workers to flight attendants, disruptions in circadian rhythms are a risk factor for metabolic disorders. Several sessions held at the recent EASL meeting focused on that link, and how disturbances in the internal clock may increase the risk of hepatic disorders.
Cyclophilins are a group of proteins involved in cell metabolism and homeostasis. One of the members, CypD, is located in mitochondria and plays an important role as a regulator of mitochondrial permeability transition (mPT) and necrotic cell death resulting in persistent mPT opening that, in turn, leads to hepatic ischemia/reperfusion injury (IRI).
The French government is officially launching a major national program for digital health. This priority research program and equipment (PEPR) in digital health is being piloted by two major government research bodies, the National Institute for Health and Medical Research (INSERM) and the National Institute for Research in Digital Science and Technology (INRIA). It has a budget of $65 million over seven years
Researchers from INSERM, Samsara Sciences Inc., Sorbonne University and Université Paris Cité have described autophagy inducers reported to be useful for the treatment of cancer, age-related disorders and viral infections.
Interactions between the gut microbiome and immune system influence cancer immune surveillance, though the mechanism through which these gut-primed immune cells regulate peripheral antitumor immune response is not well understood. Now, two recent studies in Science and Science Immunology using mouse models and human tissue samples have highlighted a group of intestinal T cells with the gut-homing α4β7 integrin receptors that play a critical role in mediating response to immune checkpoint blockade cancer immunotherapy.
Researchers from Centre National de la Recherche Scientifique, Inserm, Institut Curie and Uniwersytet im Adama Mickiewicza have prepared nitrogen-containing salinomycin derivatives reported to be useful for the treatment of cancer.
The mTORC2 complex plays an important role in the PI3K/AKT/mTOR pathway, allowing activation of AKT and contributing to the development of BRAF-mutated (BRAFm) melanomas and their resistance to treatments. Researchers from Inserm aimed to identify new candidates for targeting the mTORC2 complex in melanoma, with focus on one principal protein of this complex, MAPKAP1 (also known as SIN1).
Centre Hospitalier Regional Universitaire de Lille, Centre National de la Recherche Scientifique, INSERM and Institut Pasteur de Lille have synthesized efflux pump inhibitors reported to be useful for the treatment of gram-negative bacterial infections.
SUMOylation is a post-translational modification consisting of the covalent addition of SUMO peptides on a target protein, which can affect various processes such as protein stability, interactions or subcellular localizations. This modification finetunes protein function involved in the cellular response to stress, differentiation and tissue development.
The mutant gene causing Huntington’s disease (HD) is active from the earliest stages of brain development, even though the pathology is not evident until between 30 and 50 years of age. That delay is ascribed to plasticity enabling the brain to compensate to such an extent that overt signs of disease take time to develop. As a result, it is difficult to plot a route from early molecular defects to development of HD several decades later.
