Molecular Biology & Biomarker
A biomarker is an attribute that can be studied as an indicator of pathogenic and biological operation along with pharmacological retort to a therapeutic involvement. These are used for many purposes including disease diagnosis and prognoses of treatment retort. Biomarkers are molecules that are detected and calibrated in parts of the body like the blood or tissue. They indicate either normal or diseased activity in the body. Biomarkers are specific molecules, genes, gene products, hormones, cells or enzymes. Tumour markers are made from normal cells and cancer cells. These are the substances which are produced by cancer cell or any other cells of the body in response to cancer or certain benign conditions. These substances are found in the blood, urine, stool, tumour tissue or any other tissues or from bodily fluids of some patients with cancer. Most tumour markers are proteins. Moreover,recently, designs of gene expression and reform to DNA have also begun to be used as tumour markers. Markers of the latter one are evaluated in tumour tissue specifically. Till now, above 20 tumour markers have been distinguished and are in clinical use. Routine clinical use are characterized by oncology biomarkers. These can be detected and measured in parts of the body like blood or tissue. Awareness on cancer biomarkers has elevated in recent years highly giving great opportunities for benefiting the operation of cancer patients by improving the efficiency of detection and efficacy of treatment. New examination has been enabled for many biomarkers after Recent technological advancement and has renewed interest in flourishing new biomarkers.
