Molecular and Genetic Mechanisms Involved in the Pathogenesis of Cardiorenal Cross Talk

Area of Science:

• Cardiology
• Nephrology
• Genetics

Background:

• Cardiorenal syndrome (CRS) describes the co-occurrence of cardiac and renal dysfunction.
• Established mechanisms include inflammation, oxidative stress, apoptosis, and immune dysregulation.
• The intricate crosstalk between the heart and kidneys is not fully understood.

Purpose of the Study:

• To review emerging mechanisms in cardiorenal crosstalk.
• Focus on epigenetics, prenatal programming, noncoding RNAs, and extracellular vesicles.
• Elucidate their potential roles in heart and kidney diseases.

Main Methods:

• Literature review of recent research.
• Analysis of studies investigating novel molecular pathways.
• Synthesis of findings on cardiorenal interactions.

Main Results:

• Epigenetic modifications, prenatal programming, small noncoding RNAs, and extracellular vesicles are implicated in CRS pathogenesis.
• These factors offer new perspectives on the complex heart-kidney axis.
• Understanding these mechanisms could reveal therapeutic targets.

Conclusions:

• Emerging mechanisms like epigenetics and noncoding RNAs significantly contribute to cardiorenal crosstalk.
• Further research into these pathways is crucial for advancing CRS understanding and treatment.
• These novel factors represent a paradigm shift in studying heart and kidney disease interactions.
