Comprehensive Analysis of Drug Response using the FLICK Assay

Area of Science:

• Cell Biology
• Pharmacology
• Biochemistry

Background:

• Accurate quantification of drug-induced cell death is crucial for understanding drug efficacy.
• Existing methods face challenges due to the diversity of regulated cell death pathways and transient hallmark features.
• Many assays neglect the impact of drugs on cell proliferation, complicating data interpretation.

Purpose of the Study:

• To introduce and detail the FLICK assay for quantifying drug-induced cell death.
• To provide guidance on troubleshooting the FLICK assay across various biological materials.
• To demonstrate the utility of the FLICK assay in assessing contributions of distinct cell death types to drug responses.

Main Methods:

• The FLICK assay measures total cell death independent of specific death pathway activation.
• This method simultaneously quantifies cell death levels and population size/proliferation rates.
• The manuscript details the assay's application and troubleshooting for diverse biological samples.

Main Results:

• The FLICK assay offers a robust method for measuring total cell death.
• It provides insights into cell proliferation dynamics alongside cell death quantification.
• The assay enables the deconvolution of contributions from different cell death subtypes.

Conclusions:

• The FLICK assay is a versatile tool for comprehensive analysis of drug-induced cell death.
• It addresses key limitations of conventional assays, improving the assessment of drug efficacy.
• This method enhances the understanding of cell death mechanisms and their role in drug response.
