Neurogranin Regulates Alcohol Sensitivity through AKT Pathway in the Nucleus Accumbens.

Dysfunction of glutamate neurotransmission in the nucleus accumbens (NAc) has been implicated in the pathophysiology of alcohol use disorders (AUD). Neurogranin (Ng) is exclusively expressed in the brain and mediates N-methyl-d-aspartate receptor (NMDAR) hypo-function by regulating the intracellular calcium-calmodulin (Ca -CaM) pathway. Ng null mice (Ng mice) demonstrate increased alcohol drinking compared to wild-type mice, while also showing less tolerance to the effect of alcohol.

Serum levels of DNAJB9 are elevated in fibrillary glomerulonephritis patients.

Fibrillary glomerulonephritis (FGN) is a rare glomerular disease. Kidney biopsy is required to establish the diagnosis. Recent studies have identified abundant glomerular deposition of DNAJB9 as a unique histological marker of FGN.

Altered Skeletal Muscle Mitochondrial Proteome As the Basis of Disruption of Mitochondrial Function in Diabetic Mice.

Insulin plays pivotal role in cellular fuel metabolism in skeletal muscle. Despite being the primary site of energy metabolism, the underlying mechanism on how insulin deficiency deranges skeletal muscle mitochondrial physiology remains to be fully understood. Here we report an important link between altered skeletal muscle proteome homeostasis and mitochondrial physiology during insulin deficiency.
