PKN2 and Cdo interact to activate AKT and promote myoblast differentiation.

Skeletal myogenesis is coordinated by multiple signaling pathways that control cell adhesion/migration, survival and differentiation accompanied by muscle-specific gene expression. A cell surface protein Cdo is involved in cell contact-mediated promyogenic signals through activation of p38MAPK and AKT. Protein kinase C-related kinase 2 (PKN2/PRK2) is implicated in regulation of various biological processes, including cell migration, adhesion and death.

Kazinol-P from Broussonetia kazinoki enhances skeletal muscle differentiation via p38MAPK and MyoD.

The activation of MyoD family transcription factors is critical for myogenic differentiation, which is fundamental to the regeneration of skeletal muscle after injury. Kazinol-P (KP) from Broussonetia kazinoki (B. kazinoki), a natural compound, has been reported to possess an anti-oxidant function.

Tetrahydropalmatine promotes myoblast differentiation through activation of p38MAPK and MyoD.

Myoblast differentiation is fundamental to the development and regeneration of skeletal muscle after injury or disease. MyoD family transcription factors play a key role to promote myoblast differentiation. In a screen for MyoD activators, we identified tetrahydropalmatine (THP), a natural compound isolated from Corydalis turtschaninovii.
