Interplay Between Extracellular Matrix Remodeling and Angiogenesis in Tumor Ecosystem

Area of Science:

• Oncology
• Cancer Biology
• Tumor Microenvironment Research

Background:

• Tumorigenesis involves complex interactions within the dynamic tumor ecosystem, including cancer cells, extracellular matrix (ECM), and various stromal cells.
• The tumor microenvironment, shaped by ECM remodeling and stromal cancer-associated fibroblasts (CAFs), promotes angiogenesis and aggressive tumor growth.

Purpose of the Study:

• To explore effective cancer treatment modalities by studying tumorigenesis mechanisms and tumor ecosystem interactions.
• To investigate the role of targeting angiogenesis and ECM in overcoming therapeutic resistance and reducing tumor burden.

Main Methods:

• Analysis of the composition and dynamic evolution of the tumor ecosystem.
• Examination of ECM remodeling processes, including synthesis, degradation, and growth factor release.
• Investigation of CAF-secreted factors and their interaction with ECM to promote angiogenesis and tumor progression.

Main Results:

• Targeting angiogenesis leads to vascular changes, facilitating ECM remodeling, metastasis, and chemoresistance.
• Denser and stiffer ECM significantly contributes to chemoresistance.
• Stromal CAFs release angiogenic cues that enhance tumor cell migration and growth.

Conclusions:

• Targeting angiogenesis and ECM components offers a promising strategy for cancer treatment.
• Context-specific targeting of angiogenesis and ECM can enhance conventional therapy effectiveness.
• Addressing these elements is key to overcoming therapeutic resistance and reducing overall tumor burden.
