Measurement of catestatin and vasostatin in wild boar Sus scrofa captured in a corral trap

Le résumé fourni par la source

OBJECTIVE: Our aim was to analyse the chromogranin A-derived peptides vasostatin and catestatin in serum from wild boar (Sus scrofa) captured in a corral trap. Acute capture-related stress quickly leads to a release of adrenalin and noradrenalin, but these hormones have a short half-life in blood and are difficult to measure. Chromogranin A (CgA), a glycoprotein which is co-released with noradrenalin and adrenalin, is relatively stable in circulation and the CgA-derived peptides catestatin and vasostatin have been measured in domestic species, but not yet in wildlife. RESULTS: Vasostatin and catestatin could be measured and the median (range) serum concentrations were 0.91 (0.54-2.86) and 0.65 (0.35-2.62) nmol/L, respectively. We conclude that the CgA-derived peptides vasostatin and catestatin can be measured in wild boar serum and may thus be useful as biomarkers of psychophysical stress.
