Mammalian skeletal muscle mainly consists of four different types of muscle fibers, which are composed of different myosin types and metabolic characteristics. These muscle fibers include oxidative ...

Melatonin induces fiber switching by improvement of mitochondrial oxidative capacity and function via NRF2/RCAN/MEF2 in the vastus lateralis muscle from both sex Zücker diabetic fatty rats.

Muscle fibers are divided into three types: slow twitch (type I) or red fibers due to the large number of mitochondria they possess, fast twitch (type IIb) or white fibers and intermediate (type ...

Muscle fibers are divided into three types: slow twitch (type I) or red fibers due to the large number of mitochondria they possess, fast twitch (type IIb) or white fibers and intermediate (type IIa).

The high metabolic requirements of these fast-spiking cells may render them susceptible to redox dysregulation and oxidative stress. Using mice carrying a genetic redox imbalance, we demonstrate that ...
