Manganese availability determines insulin sensitivity by enhancing Akt activity

Jennifer R. Gamarra, Sei Higuchi, Timothy L. Yuan…·Rebecca A. Haeusler

This study identifies manganese as a regulator of Akt activity independent of PI3K, showing it enhances Akt catalytic efficiency and interacts with insulin to modulate glucose homeostasis.

Insulin sensitization by hepatic FoxO deletion is insufficient to lower atherosclerosis in mice

María Concepción Izquierdo, Michael Harris, Niroshan Shanmugarajah…·Rebecca A. Haeusler

This study shows that improving systemic insulin sensitivity via hepatic FoxO deletion does not reduce atherosclerosis in mice and may even increase it.
