Guidelines for evaluating myocardial cell death.

Area of Science:

• Cardiovascular Research
• Cell Biology
• Pathology

Background:

• Cell death is integral to cardiac pathologies, contributing to adverse cardiac remodeling and heart failure.
• Multiple forms of regulated cell death (RCD) are implicated in heart disease progression.
• There is a growing need for standardized methods to assess RCD in the myocardium.

Purpose of the Study:

• To establish best practices for evaluating myocardial cell death.
• To provide a comprehensive overview of current methods for assessing RCD in cardiac research.
• To address concerns regarding rigor and reproducibility in the study of cardiac cell death.

Main Methods:

• Review and description of established and emerging methods for identifying and quantifying myocardial cell death.
• Detailed explanation of techniques applicable to apoptosis, necroptosis, mitochondrial-mediated necrosis, pyroptosis, ferroptosis, and autophagic cell death.
• Discussion of the strengths and limitations of various evaluation approaches.

Main Results:

• Identification of six major forms of RCD relevant to cardiac pathologies: apoptosis, necroptosis, mitochondrial-mediated necrosis, pyroptosis, ferroptosis, and autophagic cell death.
• Outline of best practices for the accurate measurement and evaluation of these cell death modalities.
• Highlighting the limitations inherent in current methodologies for assessing cardiac cell death.

Conclusions:

• Standardized guidelines are essential for advancing the field of myocardial cell death research.
• Accurate evaluation of RCD is critical for understanding heart failure pathogenesis.
• Further refinement of methodologies will enhance the reliability and reproducibility of cardiac cell death studies.
