Multiple aspects of matrix stiffness in cancer progression

Area of Science:

• Oncology
• Biophysics
• Biochemistry

Background:

• The extracellular matrix (ECM) significantly influences cell behavior, but its role in cancer progression is complex.
• Tumor-associated ECM remodeling, known as desmoplasia, creates a rigid microenvironment with both pro- and anti-tumorigenic effects.
• The matrisome, encompassing all ECM proteins, is dynamically altered in cancer, impacting tumor development.

Purpose of the Study:

• To review the influence of the tumor microenvironment's biomechanical and biophysical properties on cancer cells.
• To explore how ECM changes affect tumor progression across different cancer types.
• To highlight mechanotransduction pathways and matrisome components as potential therapeutic targets.

Main Methods:

• Literature review focusing on the extracellular matrix (ECM) and tumor microenvironment.
• Analysis of desmoplasia, inflammation, and mechanotransduction in cancer.
• Examination of matrisome alterations in various solid tumors.

Main Results:

• The ECM's physical and chemical properties critically regulate cell functions, including those in tumors.
• Desmoplasia involves increased fibroblasts and ECM deposition, altering tumor mechanics and behavior.
• Inflammation and cytokines play key roles in ECM remodeling and tumor progression.

Conclusions:

• ECM variations significantly impact tumor development, acting as potential drivers alongside oncogenes.
• Mechanotransduction pathways offer promising targets for novel cancer therapies.
• Understanding matrisome dynamics is crucial for targeted interventions in pancreatic, breast, lung cancers, and mesothelioma.
