|
• 4 month old heterozygous females and males survived 33.3% and 18.2% longer, respectively, when exposed to 80% oxygen compared to wild-type mice
• dietary restriction (65% of ad libitum) further increases the survival time of heterozygous males and females kept in 80% oxygen
• when exposed to 80% oxygen survival of ovariectomized heterozygous females is decreased and survival of estradiol (E2) treated heterozygous males is increased compared to untreated sex-matched heterozygotes
|
|
• 4 month old heterozygous females and males began to die around 48 hours (similar to wild-type) after paraquat injection but survived longer overall compared to wild-type
|
|
|
• seen in 6% of heterozygous males but not in females; however, no increase in urinary glucose is seen
|
|
• seen in males and females in the fed state
|
|
|

• estradiol (E2) treatment improved glucose tolerance in males
|
|
|
• seen in heterozygous females
|
|
|
• seen in heterozygous males
• estradiol (E2) treatment improved insulin sensitivity
|
|
• 4 month old heterozygous females and males began to die around 48 hours (similar to wild-type) after paraquat injection but survived longer overall compared to wild-type
|
|
• fat mass is decreased by 41.3% and 57.5% in heterozygous females and males, respectively, compared to wild-type mice; however, no difference in food intake is seen
• when food intake is restricted to 65% of ad libitum, heterozygous females and males still have decreased fat mass compared to dietary restricted wild-type mice
|
|
• manganese superoxide dismutase activity is increased 39.9% and 22.9% in the livers of heterozygous females and males, respectively, compared to wild-type mice
