cardiovascular system

increased cardiac muscle glycogen level ( J:123005 )

• myocytes exhibit increased glycogen content compared with wild-type cells that is not as severe as in myocytes from Tg(Myh6-PRKAG2*T400N)1Feah mice

increased heart weight ( J:123005 )

• mice exhibit increased heart weight compared with wild-type mice that is not as severe as in Tg(Myh6-PRKAG2*T400N)1Feah mice

abnormal heart left ventricle morphology ( J:123005 )

• mice exhibit increased left ventricular anterior wall thickness (LVAWT) compared with wild-type mice that is not as severe as in Tg(Myh6-PRKAG2*T400N)1Feah mice

• however, left ventricular end diastolic diameter is normal

decreased heart ventricle muscle contractility ( J:123005 )

• at 20 weeks, fractional shortening is reduced compared to in wild-type mice but not as severely as in Tg(Myh6-PRKAG2*T400N)1Feah mice

homeostasis/metabolism

increased cardiac muscle glycogen level ( J:123005 )

• myocytes exhibit increased glycogen content compared with wild-type cells that is not as severe as in myocytes from Tg(Myh6-PRKAG2*T400N)1Feah mice

muscle

increased cardiac muscle glycogen level ( J:123005 )

• myocytes exhibit increased glycogen content compared with wild-type cells that is not as severe as in myocytes from Tg(Myh6-PRKAG2*T400N)1Feah mice

decreased heart ventricle muscle contractility ( J:123005 )

• at 20 weeks, fractional shortening is reduced compared to in wild-type mice but not as severely as in Tg(Myh6-PRKAG2*T400N)1Feah mice

growth/size/body

increased heart weight ( J:123005 )

• mice exhibit increased heart weight compared with wild-type mice that is not as severe as in Tg(Myh6-PRKAG2*T400N)1Feah mice
