Translational proteomics plays a key role in identifying clinically relevant protein biomarkers, swiftly progressing from discovery to validation. These biomarkers have significantly enhanced disease diagnosis, enabling monitoring, predicting recurrence, and guiding therapeutic interventions. While genetic markers highlight susceptibility, they fall short in confirming disease presence. Phenotypic markers, particularly alterations in protein expression, are crucial for this purpose. Clinical proteomics, concentrating on uncovering protein biomarkers, represents a pivotal advancement for personalized, early disease detection, diagnosis, and treatment.
