Insights

Cardiac extracellular matrix (ECM) changes are common in heart diseases. Circulating collagen peptides may serve as useful biomarkers for diagnosing and predicting heart failure (HF).

Area of Science:

  • Cardiology
  • Biochemistry
  • Biomarker Discovery

Background:

  • Extracellular matrix (ECM) alterations are hallmarks of major cardiac diseases, including ischemic, pressure overload, and volume overload heart diseases, as well as cardiomyopathies.
  • Collagen types I and III are key myocardial structural proteins, and their circulating pro- or telopeptides can indicate collagen synthesis and degradation.

Purpose of the Study:

  • To review and summarize published data on cardiac ECM and its circulating biomarkers.
  • To analyze studies focusing on collagen metabolism biomarkers in heart failure (HF) patients.
  • To discuss limitations in the clinical application of these biomarkers.

Main Methods:

  • Literature review of studies on cardiac ECM and collagen metabolism biomarkers.
  • Analysis of clinical trial data concerning diagnostic and prognostic utility in heart failure.
  • Discussion of current limitations for clinical use.

Main Results:

  • Circulating collagen peptides show potential as non-invasive indicators of ECM remodeling in cardiovascular diseases.
  • These biomarkers may reflect disease activity and progression in heart failure patients.
  • Clinical trials are exploring their diagnostic and prognostic value.

Conclusions:

  • Cardiac ECM remodeling is a significant factor in heart disease.
  • Circulating collagen peptides offer a promising avenue for biomarker development in cardiology.
  • Further research is needed to overcome limitations for widespread clinical adoption.

The Extracellular Matrix

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...

Extracellular Matrix

Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...

Role of Matrix Metalloproteases in Degradation of ECM

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...

Collagens are the Major Structural Proteins of ECM

Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers. Collagen fiber is made from fibrous protein subunits linked together to form a long, straight fiber. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength. These fibers hold connective tissues together, even during the body's movement.
Connective tissue proper includes loose...

Overview of Cell-Matrix Interactions

The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...
