Fluorescent protein biosensors, particularly those using fluorescence resonance energy transfer (FRET), enable visualization of cellular mechanical signaling (mechanotransduction). This review details FRET biosensor development and applications in live-cell mechanobiology research.
Area of Science:
- Cell Biology
- Biophysics
- Molecular Imaging
Background:
- Genetically-encoded fluorescent proteins (FPs) like green fluorescent protein (GFP) allow visualization of cellular processes.
- Fluorescence resonance energy transfer (FRET) biosensors offer insights into molecular dynamics at subcellular levels.
- Mechanotransduction, the process of cells responding to mechanical stimuli, is a key area of study.
Purpose of the Study:
- To review the development of FPs and FRET biosensors.
- To describe various FRET biosensors based on FPs.
- To highlight applications of FRET biosensors in visualizing cellular mechanotransduction.
Main Methods:
- Review of literature on fluorescent proteins and FRET biosensors.
- Description of different FRET biosensor designs.
- Case studies of FRET biosensor applications in mechanobiology.
Main Results:
- FPs have evolved with diverse colors, enhancing imaging capabilities.
- FRET biosensors provide dynamic, real-time data on molecular interactions.
- Applications demonstrate FRET's utility in studying cellular responses to mechanical forces.
Conclusions:
- FRET biosensors are powerful tools for studying mechanotransduction.
- Integration with mechanical stimulation systems advances mechanobiology research.
- These tools aid in understanding cellular mechanisms in health and disease.
