Researchers uncover the role of glutaminase 2 in glucose homeostasis

Glutaminase 2 (GLS2) is a master regulator of glutaminolysis. GLS2 converts glutamine to glutamate, thereby playing a role in cellular energy production. GLS2 is abundant in the liver, and is also found in pancreatic β-cells. However, the role of GLS2 in pancreatic islets – in which both ɑ- and β- cells are present – associated with glucose metabolism is currently unknown.

Drugs targeting FXR1 may treat vascular proliferative diseases

Vascular diseases, including myocardial infarction, stroke, renal failure, and peripheral vascular disease, continue to account for one third of all mortality in the United States, Europe, and the developing world (World Health Organization, 2021).

IOB researchers identify an active multi-layer embryonic brain circuit

Using a new approach for studying live embryonic mouse brains at single-cell resolution, researchers have identified an active multi-layer circuit that forms in the cortex during an unexpectedly early stage of development. Perturbing the circuit genetically led to changes similar to those seen in the brains of people with autism. The findings are reported today in Cell by a team based at the Institute of Molecular and Clinical Ophthalmology Basel.

Study identifies pivotal role of FIBCD1 gene in neurodevelopmental disorders

A multidisciplinary study led by Vanja Nagy (LBI-RUD/CeMM/Medical University of Vienna) and Josef Penninger (UBC/IMBA) characterized a novel gene, known as FIBCD1, to be likely causative of a new and rare neurodevelopmental disorder.

Researchers characterize a novel gene likely to cause neurological disorders in humans

A multidisciplinary study led by Vanja Nagy (LBI-RUD/CeMM/MedUni Vienna) and Josef Penninger (UBC/IMBA) characterized a novel gene, known as FIBCD1, to be likely causative of a new and rare neurodevelopmental disorder. Using data from two young patients with neurological symptoms, the researchers from both groups found evidence of a novel function for the FIBCD1 gene in the brain, and a potentially pivotal role in diseases such as autism, ADHD, schizophrenia, and neurodegenerative disorders including Alzheimer's. The study makes an important contribution to the understanding of the extracellular matrix in the brain and its associated neurological diseases.

Cancer cells produce small amount of collagen that impacts tumor microbiome and immunity

Cancer cells produce small amounts of their own form of collagen, creating a unique extracellular matrix that affects the tumor microbiome and protects against immune responses, according to a new study by researchers at The University of Texas MD Anderson Cancer Center.

Researchers identify CLCN6 as disease gene for severe lysosomal neurodegenerative disorder

A mutation in the CLCN6 gene is associated with a novel, particularly severe neurodegenerative disorder. Scientists from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie and the Max Delbrück Center für Molekulare Medizin, together with an international team of researchers, have now analyzed the effect of a point mutation that was found in three unrelated affected children.
