Regulated Cell Death Pathways in Pathological Cardiac Hypertrophy

Area of Science:

• Cardiovascular Biology
• Cellular Biology
• Molecular Medicine

Background:

• Cardiac hypertrophy is an enlargement of cardiomyocytes, not an increase in number.
• Pathological cardiac hypertrophy, triggered by adverse stimuli, impairs cardiac function and can progress to heart failure.
• Regulated cell death (RCD) pathways, including apoptosis, pyroptosis, ferroptosis, necroptosis, and autophagy, play critical roles in this process.

Purpose of the Study:

• To review the molecular mechanisms and signaling pathways of RCD in pathological cardiac hypertrophy.
• To highlight findings related to the mechanism of action of RCD pathways in this condition.
• To propose novel cellular-level therapeutic strategies for preventing or reversing pathological cardiac hypertrophy.

Main Methods:

• Literature review of molecular mechanisms and signaling pathways.
• Analysis of RCD pathways (apoptosis, pyroptosis, ferroptosis, necroptosis, autophagy).
• Focus on findings related to the mechanism of action in pathological cardiac hypertrophy.

Main Results:

• Detailed summary of molecular mechanisms underlying various RCD pathways.
• Explanation of signaling cascades involved in RCD during cardiac hypertrophy.
• Identification of specific RCD pathways contributing to pathological cardiac hypertrophy progression.

Conclusions:

• RCD pathways are integral to the pathogenesis of pathological cardiac hypertrophy.
• Understanding these pathways offers opportunities for targeted cellular therapies.
• Therapeutic strategies aimed at modulating RCD could prevent or reverse cardiac hypertrophy and heart failure.
