Environmental enrichment normalizes metabolic function in the murine model of Prader-Willi syndrome Magel2-null mice

Background Prader-Willi syndrome (PWS) is a rare genetic disease that causes developmental delays, intellectual impairment, constant hunger, obesity, endocrine dysfunction, and various behavioral and neuropsychiatric abnormalities. Standard care of PWS is limited to strict supervision of food...

Insulin secretion deficits in a Prader-Willi syndrome β-cell model are associated with a concerted downregulation of multiple endoplasmic reticulum chaperones

Prader-Willi syndrome (PWS) is a multisystem disorder with neurobehavioral, metabolic, and hormonal phenotypes, caused by loss of expression of a paternally-expressed imprinted gene cluster. Prior evidence from a PWS mouse model identified abnormal pancreatic islet development with retention of...

Magel2 truncation alters select behavioral and physiological outcomes in a rat model of Schaaf-Yang syndrome

Previous studies in mice have utilized Magel2 gene deletion models to examine the consequences of its absence. We report the generation, molecular validation and phenotypic characterization of a novel rat model with a truncating Magel2 mutation modeling variants associated with Schaaf-Yang...
