Delaying cardiac aging: potential mechanisms centered on PANoptosis and targeted intervention strategies

Area of Science:

• Cardiovascular biology
• Cellular aging mechanisms
• Molecular pathology

Background:

• Cardiac aging is a major public health concern, linked to decreased quality of life and longevity.
• Existing interventions for cardiac aging, such as senolytics, show limited efficacy.
• Novel therapeutic targets are needed to address the growing burden of age-related heart disease.

Purpose of the Study:

• To review the molecular mechanisms and role of PANoptosis in cardiac aging.
• To explore PANoptosis as a potential therapeutic target for age-related cardiac dysfunction.
• To summarize evidence linking PANoptosis to cardiomyocyte loss, fibrosis, and inflammation in the aging heart.

Main Methods:

• Literature review of studies on PANoptosis and cardiac aging.
• Analysis of molecular pathways regulating PANoptosis in cardiomyocytes.
• Evaluation of preclinical intervention strategies targeting PANoptosis.

Main Results:

• PANoptosis, an integrated cell death pathway, is implicated in accelerating cardiac aging.
• PANoptosis contributes to cardiac functional decline through cardiomyocyte loss, fibrosis, and chronic inflammation.
• Targeted interventions for PANoptosis show significant therapeutic potential in preclinical models.

Conclusions:

• PANoptosis represents a novel and promising target for therapeutic strategies against cardiac aging.
• Understanding PANoptosis regulatory networks is crucial for developing effective anti-aging cardiac therapies.
• Further research into PANoptosis-targeted interventions could lead to new treatments for age-related heart conditions.
