Hypothesis

CREB activation contributes to muscle regeneration after injury.

Conclusion

Activated CREB promotes myoblast proliferation and enhances muscle regeneration in mice.

Supporting Evidence

  • CREB phosphorylation is induced after acute muscle injury.
  • Activated CREB promotes myoblast proliferation in vitro.
  • Genetic activation of CREB enhances muscle regeneration in dystrophic mice.

Takeaway

When muscles get hurt, a protein called CREB helps the muscle cells grow and heal faster.

Methodology

The study used mouse models and primary myoblast cultures to investigate the role of CREB in muscle regeneration.

Participant Demographics

Mice, including wild-type and genetically modified strains.
