MYOD1 and gas gangrene: As far as red PBM effects on skeletal muscle in animal models are concerned, it has been shown that red laser irradiation (685 nm, 4 or 4.2 J/cm2) was able to significantly decrease venom‐induced myonecrosis in mice [92, 93] and that red laser stimulation (660 nm, 10, 50 J/cm2) accelerated the muscle regeneration process in a rat model of muscle cryolesion by increasing MyoD and myogenin gene expression [68].
