MAP4 as a New Candidate in Cardiovascular Disease

Area of Science:

• Cardiovascular Biology
• Cellular Biology
• Molecular Medicine

Background:

• Microtubule and mitochondrial dysfunction are key factors in cardiovascular diseases (CVDs) like cardiac hypertrophy and heart failure.
• These cellular dysfunctions lead to disrupted homeostasis, altered metabolism, increased cell death, and inflammation, ultimately causing cardiac injury.

Purpose of the Study:

• To review the emerging role of microtubule-associated protein 4 (MAP4) in cardiovascular pathologies.
• To highlight MAP4 as a potential therapeutic target for CVDs.

Main Methods:

• This review synthesizes existing research on MAP4's function in microtubule dynamics and mitochondrial homeostasis.
• Literature analysis focusing on MAP4's involvement in cardiac hypertrophy, fibrosis, heart failure, and ischemic heart dysfunction.

Main Results:

• MAP4 plays a critical role in regulating microtubule stability; increased MAP4 phosphorylation leads to instability.
• MAP4 is also present in mitochondria, where its phosphorylation promotes apoptosis and contributes to cardiac injury.
• Dysfunctional MAP4 impacts both microtubule and mitochondrial integrity, exacerbating CVD pathogenesis.

Conclusions:

• MAP4 is implicated in the pathogenesis of various cardiovascular diseases.
• MAP4's dual role in microtubule and mitochondrial function makes it a promising candidate for novel therapeutic interventions in CVDs.
