Annotation of the Effect of Chemogenomic Compounds on Cell Health Using High-Content Microscopy in Live-Cell Mode

Area of Science:

• Cell Biology
• Drug Discovery
• High-Content Screening

Background:

• Phenotypic responses are crucial for annotating chemogenomic libraries.
• Assessing general cellular health effects is essential for drug discovery.
• Existing methods may not capture comprehensive cellular health parameters.

Purpose of the Study:

• To develop and present a multidimensional live cell assay for characterizing chemogenomic libraries.
• To evaluate cell viability, nuclear morphology, tubulin structure, mitochondrial health, and membrane integrity.
• To establish a versatile protocol adaptable to various cell lines and cellular health parameters.

Main Methods:

• Utilized a multidimensional high-content live cell assay.
• Monitored osteosarcoma cells, human embryonic kidney cells, and human fibroblasts over a 48-hour time course.
• Assessed cell viability through nuclear morphology, tubulin structure, mitochondrial health, and membrane integrity.

Main Results:

• The assay successfully monitored multiple parameters of cellular health in different cell lines.
• Demonstrated the capability to examine the effects of small molecules on cellular structures and functions.
• Provided a detailed time-course analysis of cellular responses.

Conclusions:

• The described live cell assay is easily established and adaptable for broad applications.
• This protocol facilitates comprehensive characterization of chemogenomic libraries.
• The assay provides essential data for annotating phenotypic responses and advancing drug discovery.
