Nuclear mechanotransduction: forcing the nucleus to respond

Area of Science:

• Cell Biology
• Biophysics
• Mechanobiology

Background:

• Cell phenotype and fate are influenced by the mechanical properties of the surrounding microenvironment.
• Mechanical forces and matrix rigidity significantly alter cell behavior and phenotype.
• Molecular mechanisms sensing and transducing mechanical signals into biochemical pathways are central to cell biology.

Purpose of the Study:

• To discuss recent evidence of mechanotransduction occurring within the nucleus.
• To review the dynamic regulation of the nucleoskeleton in response to mechanical stress.
• To examine the impact of nucleoskeletal response on nuclear structure and function.

Main Methods:
