Comparative Study
Identification of an Adrenomedullin precursor fragment in plasma of sepsis patients.
Adrenomedullin and PAMP are potent vasodilatory peptides derived from a common larger precursor peptide. Elevation of circulating levels of both peptides has been described for diseases involving dysfunction of the cardiovascular system. ⋯ This peptide is produced in stoichiometric amounts to Adrenomedullin and PAMP, but -- contrary to them -- is apparently non-functional and stable. Thus, proADM 45-92 represents a suitable diagnostic target which could be used to assess the concentrations of Adrenomedullin gene products released into the bloodstream.
