The Science Behind ColonSentry
The Sentinel Principle® is a patent protected, platform technology which utilizes functional genomics to enable early identification of disease.
- Circulating blood reflects, in a detectable way, what is occurring throughout the body.
- As blood circulates communication occurs between cells in blood and tissue.
- Subtle changes that occur in cells due to injury or disease trigger detectable, specific changes in blood cell gene expression.
- Profiling these changes generates unique molecular signatures reflecting disease activity.
- These molecular signatures can be used to identify disease-specific blood biomarkers.
- These biomarkers are the foundation for ColonSentry’s highly sensitive and specific molecular diagnostic assay.
Why use blood?
- tissue-specific gene transcripts including beta-myosin-heavy chain (heart specific) and insulin (specific to pancreatic islet beta cells) can be detected circulating blood cells
- suggest that although the expression level of genes may vary among different tissue or cell types, most genes may be expressed in the blood at a detectable level
- blood cells can act as sentinels of disease and that could be used for the diagnosis/prognosis of disease (the “Sentinel Principle”).
- Peripheral blood is an ideal surrogate tissue as it is readily obtainable and response to changes in the macro-and micro-environments is detectable as alterations in the levels of these gene transcripts
