The Extracellular Matrix and Vesicles Modulate the Breast Tumor Microenvironment

Area of Science:

• Oncology
• Cell Biology
• Biochemistry

Background:

• The tumor microenvironment (TME) significantly influences breast cancer progression, metastasis, and immune evasion.
• Extracellular matrix (ECM) composition and signaling molecules within the TME are key drivers of cancer development.
• Extracellular vesicles (EVs) are emerging as critical mediators of cell-to-cell communication within the TME.

Purpose of the Study:

• To review the multifaceted roles of ECM and TME in breast cancer.
• To highlight the significance of EVs and their contents in cancer progression and metastasis.
• To explore potential clinical applications of these extracellular components in breast cancer treatment.

Main Methods:

• Comprehensive literature review of studies on TME, ECM, and EVs in breast cancer.
• Analysis of signaling pathways and molecular mechanisms involved in cancer progression.
• Evaluation of current and future biomedical and clinical applications.

Main Results:

• ECM alterations in the TME are critical for breast cancer development and metastasis.
• EVs facilitate tumor progression and immune evasion by transferring signaling molecules.
• The biomolecular cargo of EVs significantly impacts breast cancer metastasis.

Conclusions:

• ECM and EVs are pivotal regulators of breast cancer progression and metastasis.
• Targeting ECM and EVs presents promising therapeutic strategies for breast cancer.
• Further research into EVs and ECM holds potential for improved breast cancer diagnostics and therapeutics.
