MGI:6510865

• Allelic Composition: Gpr82^tm1Shbg/Gpr82^tm1Shbg
• Genetic Background: C3Fe.Cg-Gpr82^tm1Shbg

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

adipose tissue

abnormal adipose tissue amount ( J:301613 )

♀ • reduction in visceral fat mass

♀ • fat tissue from Western diet-fed mice shows a diet-induced increase in the fat-to-water ratio; this is not seen on a standard diet

decreased total body fat amount ( J:301613 )

♀ • lower absolute and relative body fat content

decreased fat cell size ( J:301613 )

♀ • average size of adipocytes in perigonadal fat pads is lower

behavior/neurological

decreased food intake ( J:301613 )

♀ • food intake is reduced during the light and dark phase

abnormal locomotor circadian rhythm ( J:301613 )

♀ • mice show a reduced motor activity during the dark period but not during the light phase

decreased locomotor activity ( J:301613 )

♀ • mice show reduced locomotion in the open field

increased thermal nociceptive threshold ( J:301613 )

♀ • mice show increased heat tolerance on the hot plate test

growth/size/body

increased lean body mass ( J:301613 )

♀ • lean mass relative to the body weight is increased

decreased body weight ( J:301613 )

♀

homeostasis/metabolism

decreased circulating insulin level ( J:301613 )

♀ • fasting serum insulin levels are only slightly lower

decreased circulating VLDL cholesterol level ( J:301613 )

♀ • cholesterol is reduced only in the VLDL fraction

increased body temperature ( J:301613 )

♀ • mice show a small, but significant, increase in body temperature

♀ • however, no differences in the respiratory and metabolic rates are seen

improved glucose tolerance ( J:301613 )

♀ • mice show improved glucose tolerance in oral glucose tolerance tests

♀ • Western diet-fed mice show improved glucose tolerance following intraperitoneal glucose application

increased insulin sensitivity ( J:301613 )

♀ • females fed a Western diet show improved insulin sensitivity compared to wild-type females, indicating that diet-induced insulin resistance is reduced

decreased triglyceride level ( J:301613 )

♀ • lower triacylglyceride levels; triacylglyceride levels are lower in all three lipoprotein fractions (LDL, HDL, VLDL)
