homeostasis/metabolism
• lower serum concentration of pyruvate in mice fasted for 48 h compared to wild-type mice
|
• higher serum concentration of branched chain amino acids in mice fasted for 48 h compared to wild-type mice
|
• lower serum concentration of alanine in mice fasted for 48 h compared to wild-type mice
|
• lower serum concentration of lactate in mice fasted for 48 h compared to wild-type mice
|
• higher serum concentration of non-esterified fatty acids in mice fasted for 48 h compared to wild-type mice
|
• after 48 h of starvation, livers contain 42% less free glucose compared to similarly starved wild-type mice
• glucose oxidation rate is 36% greater in diaphragms; however, lactase release and net glycolysis rates are reduced by 37% and 35%, respectively
|
• 30% and 58% lower in 24 h and 48 h fasted mice, respectively, compared to similarly fasted wild-type mice
• however, in the fed state blood glucose levels are similar to wild-type
|
• small but significant increase in insulin levels after 48 h of starvation compared to wild-type mice
|
• slight but significant increase in glucose tolerance
• however, no difference is seen in insulin sensitivity
|
• larger decrease in liver glycogen levels induced by 24 h of starvation and a smaller rebound in levels between 24 and 48 h of starvation compared to wild-type mice
• however, the starvation-induced reduction in skeletal muscle glycogen is similar to wild-type
|
• higher serum concentration of triacylglycerol in mice fasted for 48 h compared to wild-type mice
|
• higher serum concentration of acetoacetate and beta-hydroxybutyrate in mice fasted for 48 h compared to wild-type mice
|
