Cell death assays for drug discovery

Area of Science:

• Biomedical Sciences
• Molecular Biology
• Pharmacology

Background:

• Cell death plays a critical role in numerous human diseases.
• Modulating cell death pathways offers therapeutic strategies for various disorders.
• High-throughput screening (HTS) has identified promising cytotoxic and cytoprotective agents for cancer, ischemic, and neurodegenerative diseases.

Purpose of the Study:

• To systematically describe and evaluate methods for accurately quantifying distinct cell death pathways.
• To discuss the advantages and limitations of various cell death assays.
• To focus on techniques suitable for high-throughput screening (HTS).

Main Methods:

• Systematic review of cell death quantification techniques.
• Analysis of assay performance in distinguishing between different cell death modalities.
• Evaluation of HTS compatibility for selected methods.

Main Results:

• Different cell death modalities are implicated in distinct diseases.
• Existing assays must differentiate between various cell death pathways, not just quantify overall cell death.
• Specific techniques amenable to HTS for accurate cell death pathway quantification are highlighted.

Conclusions:

• Accurate quantification and differentiation of cell death pathways are essential for effective therapeutic development.
• The described methods aid in identifying and validating novel therapeutic agents for a range of diseases.
• Focus on HTS-compatible assays accelerates the discovery of drugs targeting cell death.
