Strain description

PGC-1α/B mice are transgenic mice specifically overexpressing PGC-1α (peroxisome proliferator-activated receptor γ coactivator-1α) in skeletal muscle. This strain expresses 2.4 kb cDNA encoding mouse PGC-1α under the control of human α actin promoter on -2,000 bp. This strain observes shift in red skeletal muscle and increase of mitochondrial number, then becomes muscle atrophy at 25 weeks of age. This strain has three lines. It's known that PGC-1α, a cofactor of nuclear receptor PPARγ, promotes mitochondria synthesis.

It's considered that this strain is a model mouse of the Luft's disease, one of the mitochondrial myopathy.
