Musculoskeletal disease

Cytoglobin (CYGB)

In vitro and mouse studies suggest increasing CYGB expression could help treat muscle injury. In mouse myoblasts, siRNA against Cygb increased reactive oxygen species levels and apoptotic cell death compared with siRNA control, whereas overexpression of Cygb decreased both. In mice, skeletal muscle-specific Cygb knockout impaired postinjury regeneration of muscle and differentiation and proliferation of myogenic progenitor cells. Next steps include additional studies to determine the mechanism of CYGB activity.
