Matrix-induced nuclear remodeling and mechano-therapeutics

Area of Science:

• Biophysics
• Cell Biology
• Mechanobiology

Background:

• The extracellular matrix (ECM) provides physical cues influencing cell behavior.
• Nuclear mechanotransduction links mechanical signals to cellular responses.
• ECM properties like stiffness and topology impact cell fate.

Purpose of the Study:

• To review how ECM biophysical properties regulate nuclear mechanics and chromatin organization.
• To explore the role of matrix-driven nuclear changes in various diseases.
• To highlight therapeutic strategies targeting the matrix-nucleus axis.

Main Methods:

• Literature review of studies on ECM, nuclear mechanotransduction, and epigenetics.
• Analysis of how mechanical signals transmit from ECM to the nucleus.
• Discussion of therapeutic interventions modulating the matrix-nucleus interface.

Main Results:

• ECM stiffness, topology, and confinement modulate nuclear mechanics and chromatin accessibility.
• Matrix-driven nuclear changes influence cell fate in cancer, inflammation, fibrosis, stem cell differentiation, and aging.
• Therapeutic strategies include tuning ECM properties and targeting mechanosensitive molecules.

Conclusions:

• The matrix-nucleus axis is a critical regulator of cell fate and disease.
• Mechanically induced epigenetic regulation offers a promising therapeutic paradigm.
• Targeting nuclear mechanobiology holds potential for tissue regeneration and disease treatment.
