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.

Biomarker found in urine could help diagnose acute tubulointerstitial nephritis

In a study led by Johns Hopkins Medicine, in collaboration with Yale School of Medicine, researchers have identified a biomarker found via a simple urine test that can be used to diagnose acute tubulointerstitial nephritis (AIN), a medical condition that causes inflammation of the kidneys and can lead to acute kidney injury (AKI) — a sudden loss of kidney function.

Study finds correlation between oral microbiome, alcohol metabolism, and hangover severity

Hangovers are common among people who drink alcohol. Previous research showing that a hangover's combination of both mental and physical misery can occur after a single episode of alcohol consumption also revealed that a rapid breakdown of alcohol into acetaldehyde is associated with less severe hangovers.
