Biomarker signatures refer to specific sets of biological markers that can be used to predict or diagnose certain diseases or conditions. These markers can include proteins, genes, metabolites, or other molecules that are associated with a particular disease or physiological state. Biomarker signatures are used in many areas of research, including cancer biology, personalized medicine, and drug development, to identify and track the progression of diseases, predict patient responses to treatment, and monitor overall health. By analyzing these biomarker signatures, researchers can gain valuable insights into the underlying mechanisms of disease and develop more targeted and effective therapies.
