Fluopack screening platform for unbiased cellular phenotype profiling.

Area of Science:

• Cellular Biology
• Chemical Biology
• Genomics

Background:

• Perturbation studies are crucial for understanding gene and compound functions.
• Existing methods for capturing associated phenotypes lack unbiased and holistic approaches.
• There is a need for novel platforms to profile subcellular phenotypes comprehensively.

Purpose of the Study:

• To introduce Fluopack screening, a novel platform for profiling subcellular phenotypes.
• To demonstrate the utility of Fluopack screening in an unbiased, high-throughput manner.
• To showcase its application in characterizing orphan protein function.

Main Methods:

• Utilized imaging of fluorescent chemical probes for cellular process surveying.
• Employed segmentation-free, whole image analysis of Fluopack images.
• Applied the platform to identify probes revealing distinct phenotypes upon perturbation.

Main Results:

• Fluopack screening enables unbiased, high-throughput profiling of subcellular phenotypes.
• The approach successfully identified phenotypes overlooked by other methods, including lipid trafficking and ion concentration.
• Characterized TMEM41B as a novel regulator of lipid mobilization using this platform.

Conclusions:

• Fluopack screening is a powerful new tool for chemical biology and phenotypic profiling.
• This method facilitates the interrogation of cellular processes and the discovery of novel protein functions.
• It provides a holistic and unbiased approach to understanding perturbagen mechanisms of action.
