biomarker panel that provides information on the subsequent clinical outcome or therapeutic efficacy, which can be validated to yield a final panel, then translated into say, an ELISA - based kit or some other immunodiagnostic format in the clinical setting,» says Dorfman.
More importantly, they also identified a few proteins that previously were not known to be HCC - related, opening possibilities for
candidate biomarker development.
«We are proposing that the disease be defined in living people by evidence of brain pathology using
biomarker studies, either brain imaging or body fluid examination, and that clinical symptoms should be regarded for what they are — a product or result of the disease, as opposed to the definition of the disease,» said lead author Dr. Clifford Jack, Jr. of the Mayo Clinic.
