In biomedical contexts, a biomarker, or biological marker, is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated using blood, urine, or soft tissues [1] to examine normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. [2]
In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention."
This category collects together articles describing various biomolecules used as biomarkers. Subcategories. This category has the following 2 subcategories, out of 2 ...
Cardiac markers are biomarkers measured to evaluate heart function. They can be useful in the early prediction or diagnosis of disease. [1] Although they are often discussed in the context of myocardial infarction, other conditions can lead to an elevation in cardiac marker level. [2] [3]
A tumor marker is a biomarker that can be used to indicate the presence of cancer or the behavior of cancers (measure progression or response to therapy). They can be found in bodily fluids or tissue. Markers can help with assessing prognosis, surveilling patients after surgical removal of tumors, and even predicting drug-response and monitor ...
Other potential future biomarkers include micro RNA molecules, which cancerous cells express more of than healthy ones. [45] Cancer is a disease with excessive molecular causes and constant evolution. There's also heterogeneity of disease even in an individual.
One notable biomarker garnering significant attention is the protein biomarker S100-beta in monitoring the response of malignant melanoma. In such melanomas, melanocytes , the cells that make pigment in our skin, produce the protein S100-beta in high concentrations dependent on the number of cancer cells.
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
