Biomarker Discovery

Biomarker discovery requires several steps to identify biomolecules that can function as dependable disease or physiological condition indicators. DNA, RNA, proteins, metabolites and other small molecules which demonstrate significant expression level changes throughout disease progression can serve as biomolecules for early, advanced or treatment response disease stages. Biomarkers in oncology research serve multiple purposes, from early detection of cancer before symptoms manifest through diagnosis to predicting disease progression and patient survival with prognosis tools while assessing treatment responses and developing individualized treatment approaches based on biomarker profiles. The discovery of biomarkers demands high-throughput screening operations followed by bioinformatics analysis together with stringent validation procedures to establish both reliability and clinical usefulness.
