homeostasis/metabolism
• homozygotes display reduced total plasma cholesterol levels relative to wild-type KK mice
• however, no significant differences are observed in plasma glucose and insulin levels relative to wild-type KK mice
|
• upon electrophoretic analysis of plasma lipoproteins, homozygotes show a slight reduction in the fraction of HDL relative to wild-type KK mice
• however, HDL electrophoretic mobility is similar to that of wild-type C57BL/6J mice, suggesting that HDL cholesterol synthesis/catabolism is unaffected
|
• upon electrophoretic analysis of plasma lipoproteins, homozygotes show a reduction in the fraction of LDL relative to wild-type KK mice
|
• upon electrophoretic analysis of plasma lipoproteins, homozygotes show a reduction in the fractions of chylomicrons and VLDL relative to wild-type KK mice
|
• homozygotes display reduced total plasma non-esterified fatty acid levels relative to wild-type KK mice
|
• homozygotes show a 15% reduction in the rate of secretion of hepatic triglyceride relative to KK mice
• in addition, the rate of peripheral disposal of exogenous triglyceride is increased by 85%
|
• homozygotes display reduced plasma triglyceride levels relative to wild-type KK mice
|
• homozygotes show a 102% increase in the rate of lipoprotein lipase (LPL) activity in epididymal adipose tissue relative to wild-type KK mice
|
adipose tissue
• homozygotes display reduced gonadal fat pad weights relative to wild-type KK mice
• however, no significant differences in total body weight or liver weight are observed
