This research aims to investigate the role of Magel2 in hypothalamic neurons and its effects on stress and anxiety behaviors linked to Prader-Willi Syndrome.
Genetic elimination of Magel2 in MeA-innervating ARC Pomc neurons using a retrograde AAV with Cre recombinase
Behavioral tests including open field test, light/dark test, and elevated plus maze test were conducted
Comparison of stress-induced behaviors between male and female mice with and without Magel2 gene deletion
Male mice with Magel2 deletion showed increased stress-induced anxiety-like behavior
No changes were observed in anxiety-like behavior without acute stress exposure
Mice lacking Magel2 exhibited reduced motivation and impaired spatial learning associated with food reward.
