Summary
Extracellular matrix (ECM) biomaterials inhibit esophageal adenocarcinoma cell growth and migration. Nonmalignant esophageal ECM specifically reduces cell migration and epithelial-mesenchymal transition, suggesting therapeutic potential after surgery.
Area of Science:
- Biomaterials Science
- Cancer Biology
- Tissue Engineering
Background:
- Extracellular matrix (ECM) biomaterials are used for tissue repair.
- ECM shows promise in esophageal adenocarcinoma (EAC) resection recovery.
- Molecular mechanisms of ECM's effects on EAC are not well understood.
Purpose of the Study:
- Investigate in vitro effects of esophageal (eECM) and urinary bladder (ubECM) derived ECM on EAC cell behavior.
- Analyze ECM's impact on EAC proliferation, migration, and signaling pathways.
- Explore potential therapeutic applications of ECM in EAC treatment.
Main Methods:
- Utilized OE33 EAC cells treated with eECM and ubECM.
- Assessed cell proliferation and migration.
- Performed high-throughput cell surface marker screening.
- Analyzed gene and protein expression, including CD164, CXCR4, BMP4, and epithelial-mesenchymal transition markers.
Main Results:
- Both eECM and ubECM inhibited OE33 cell proliferation; eECM showed a stronger effect.
- Both ECM types downregulated CD164 and CXCR4.
- eECM significantly suppressed OE33 cell migration and epithelial-mesenchymal transition.
- eECM reduced BMP4 signaling pathway components.
Conclusions:
- Biochemical cues from nonmalignant ECM modulate EAC cell behavior.
- ECM-based strategies show potential for therapeutic use post-esophageal cancer resection.
- Targeting PI3K-Akt and BMP4 signaling pathways via ECM is a promising avenue.

01:23Role of Matrix Metalloproteases in Degradation of ECM
3.2K
Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult...

11.8K
Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

02:17The Tumor Microenvironment
7.6K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

02:38Mitogens and the Cell Cycle
7.7K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

01:35Cancer Cell Migration through Invadopodia
3.2K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...
