GHRL and posterior cortical atrophy: Remarkably, analysis carried out in an additional PCa patient’s cohort and controls demonstrated that acylated In1-ghrelin peptide could be detected in plasma and that these levels, but not those of native-ghrelin, are significantly higher in PCa patients than in healthy-controls, which again would suggest the possible utility of In1-ghrelin levels as a novel biomarker for PCa patients by using non-invasive (liquid) biopsies.
