Are there any biomarkers related to amino acid metabolism for cancer diagnosis or prognosis?
Yes, alterations in amino acid metabolism can serve as biomarkers for cancer diagnosis and prognosis. Elevated levels of certain amino acids, such as serine and glycine, have been associated with poor prognosis in some cancers. Additionally, the expression levels of amino acid transporters, like SLC1A5, can provide diagnostic and prognostic insights. Metabolomic profiling of amino acids in blood or tissue samples is an emerging tool for cancer biomarker discovery.
