PRKAA1 and acute liver failure: To our surprise, compared with the control AMPKα1lox/lox/AMPKα2lox/lox mice, liver-specific AMPKα1 knockout (AMPKα1LS−/−) mice were more sensitive to GalN/LPS administration but not AMPKα2LS−/−mice, and the beneficial effects of M1 on acute liver failure and the production of pro-inflammatory factors were dampened in AMPKα1LS−/− mice.
