Implication
Calcineurin-NFAT/MEF2 signaling informs hypertrophy mechanisms; leaves open targeted modulation in cardiac disease.
Key Points
- The aim is to explore how calcium signaling and calcineurin influence muscle hypertrophy and gene expression.
- Discusses the role of calcineurin as a calcium sensor in muscle cells.
- Examines the activation of transcription factors NFAT and MEF2 in muscle hypertrophy.
- Considers pharmacologic implications of these findings for muscle function.
- Calcineurin links prolonged calcium elevation to muscle gene expression changes.
- It regulates contractile and metabolic properties by activating slow muscle fiber genes.
- Transcription factors NFAT and MEF2 are critical endpoints for calcineurin's hypertrophic signaling.

Hypertrophic response and muscle gene expression
Calcineurin plays a central role in coupling Ca2+ signaling to hypertrophic gene expression in cardiac and skeletal muscle via NFAT and MEF2 transcription factors.
Cite This Study
Olson et al. (2000) conducted a review in Cardiac and skeletal muscle hypertrophy. Calcineurin and Ca2+ signaling was evaluated. Calcineurin acts as a Ca2+ sensor that couples prolonged changes in Ca2+ levels to reprogramming of muscle gene expression, controlling cardiac and skeletal muscle hypertrophy.
