PPARδ, a Potential Therapeutic Target for Heart Disease.

Area of Science:

• Cardiovascular Biology
• Molecular Endocrinology
• Metabolic Regulation

Background:

• Peroxisome proliferator-activated receptor delta (PPARδ) is a nuclear receptor regulating gene transcription.
• PPARδ plays vital roles in cardiac energy metabolism, including fatty acid and glucose oxidation, redox homeostasis, and mitochondrial function.
• PPARδ signaling is compromised in various heart diseases, such as hypertrophy, ischemia/reperfusion injury, and diabetic cardiomyopathy.

Purpose of the Study:

• To provide an updated overview of PPARδ's role in the heart.
• To discuss the complex transcriptional regulatory mechanisms of PPARδ.
• To explore the therapeutic potential of PPARδ for cardiac disorders.

Main Methods:

• Literature review of studies on PPARδ in cardiac physiology and pathology.
• Analysis of PPARδ's transcriptional targets and signaling pathways in the heart.
• Evaluation of experimental models demonstrating the effects of PPARδ deficiency or modulation in cardiac disease.

Main Results:

• PPARδ deficiency leads to cardiac dysfunction, lipid accumulation, hypertrophy, and heart failure.
• Impaired PPARδ signaling is a common feature in pathological cardiac conditions.
• PPARδ influences cardiomyocyte proliferation and inflammation.

Conclusions:

• PPARδ is essential for maintaining cardiac function and energy homeostasis.
• Dysregulation of PPARδ contributes significantly to the pathogenesis of heart failure.
• Targeting PPARδ represents a promising therapeutic strategy for treating cardiac disorders.
