| Summary |
3 genotypes
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• mitochondria in muscle cells exhibit increased cellular respiration compared with wild-type cells
|
|
• muscle cells contain increased mitochondrial DNA compared with control cells
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• most muscles in transgenic animals display a red color characteristic of oxidative muscle; in contrast, control muscles are paler in appearance
|
|
• muscles in mutant animals are able to sustain a longer duration of continuous contraction; isolated extensor digitorum longus (EDL) muscles show much greater fatigue resistance compared to control muscle
• muscle fiber diameter loss in response to denervation and fasting is less severe in transgenic animals when compared to controls
|
|
• following 5 weeks of a chronic mild stress (CMS) protocol, transgenic mice do not exhibit the increased immobility in forced swim test or decreased sucrose consumption that is observed in wild-type mice
• however, transgenic mice exhibit decreases in body weight similar to wild-type
