Targeting FoxO1 in cardiovascular diseases: Mechanisms and therapeutic potential

Area of Science:

• Molecular Biology
• Cardiology
• Biochemistry

Background:

• Cardiovascular diseases (CVDs) are a leading cause of mortality worldwide, necessitating novel therapeutic strategies.
• The Forkhead box O (FoxO) family of transcription factors are crucial regulators of diverse biological functions.
• Emerging evidence highlights the significant involvement of FoxO proteins, especially FoxO1, in cardiovascular pathophysiology.

Purpose of the Study:

• To review the structure and function of the FoxO family, with a focus on FoxO1.
• To summarize the pathological and physiological roles of FoxO1 in various cardiovascular conditions.
• To explore the regulatory mechanisms and therapeutic potential of FoxO1 in cardiovascular disease.

Main Methods:

• Literature review synthesizing current research on FoxO1 in cardiovascular disease.
• Analysis of FoxO1's involvement in key cardiovascular processes including inflammation, oxidative stress, and metabolism.
• Examination of post-translational modifications regulating FoxO1 activity in the cardiovascular system.

Main Results:

• FoxO1 significantly influences cardiac plasticity, stress response, and metabolism through various signaling pathways.
• FoxO1 is implicated in ischemia-reperfusion injury, myocardial hypertrophy, infarction, fibrosis, cardiomyopathy, and atherosclerosis.
• Key regulatory mechanisms of FoxO1 in the cardiovascular system include phosphorylation, methylation, ubiquitination, and acetylation.

Conclusions:

• FoxO1 is a critical regulator in both the physiological and pathological aspects of cardiovascular health.
• Targeting FoxO1 and its regulatory pathways presents a promising avenue for novel therapeutic interventions in CVDs.
• Further research into FoxO1 regulators is essential for translating these findings into clinical applications for cardiovascular disease management.
