Untangling the Cooperative Role of Nuclear Receptors in Cardiovascular Physiology and Disease

Area of Science:

• Cardiovascular Biology
• Molecular Cardiology
• Epigenetics

Background:

• Cardiomyocytes were traditionally viewed as transcriptionally stable cells.
• Emerging evidence highlights the critical role of transcriptional and epigenetic regulation in cardiac function and disease.
• Cardiovascular diseases (CVD) involve complex transcriptional alterations.

Purpose of the Study:

• To review the current understanding of retinoid X receptor (RXR) partnership biology in cardiac homeostasis and disease.
• To provide an updated perspective on the molecular mechanisms and cellular pathways governing cardiomyocyte physiology.
• To highlight RXRs as potential therapeutic targets for CVD.

Main Methods:

• Literature review of studies on cardiac retinoid X receptors (RXRs) and their partners.
• Analysis of molecular mechanisms and cellular pathways involved in cardiac function and disease.
• Synthesis of current knowledge on transcriptional and epigenetic regulation in the heart.

Main Results:

• Retinoid X receptors (RXRs) and their partners mediate transcriptional alterations in cardiovascular diseases.
• RXRs are nuclear receptors regulating essential processes like ion handling, mitochondrial biogenesis, and metabolism.
• Dysregulation of RXR pathways contributes to cardiac dysfunction.

Conclusions:

• Cardiac retinoid X receptors (RXRs) are crucial for maintaining heart function and are implicated in cardiovascular disease pathogenesis.
• Understanding RXR partnership biology offers insights into molecular mechanisms underlying cardiac homeostasis and disease.
• RXRs represent promising molecular targets for developing novel pharmacological strategies for CVD treatment and prevention.
