Obestatin is a 23-amino-acid peptide encoded by the same gene as ghrelin. Because there is a paucity of data concerning the effects of exercise on obestatin, this study investigated the effect of anaerobic exercise training-detraining on obestatin and growth hormone (GH) plasma levels. Ten young female volunteers participated. Blood was collected 24 h before, and 24 h, 48 h and 7 days after the training. The data indicate that anaerobic training caused a significant reduction in GH levels but had no effect on plasma obestatin concentrations.

Background: Identifying the underlying mechanisms of immune checkpoint inhibitor resistance in patients with cachexia is a current challenge. Ghrelin is a peptide hormone that plays an important role in the metabolism of patients with cancer cachexia. Despite the importance of ghrelin in cancer cachexia, most previous studies on the subject have not distinguished between the forms of ghrelin.

Liver-expressed antimicrobial peptide 2 (LEAP2) has recently emerged as a novel hormone that reduces food intake and glycemia by acting through the growth hormone secretagogue receptor (GHSR), also known as the ghrelin receptor. This discovery has led to a fundamental reconceptualization of GHSR's functional dynamics, now understood to be under a dual and opposing regulation. LEAP2 exhibits several distinctive features.

Associations between variants in the FTO locus and plasma concentrations of appetite related hormones are inconsistent, and might not work in a dose dependent fashion in people with obesity. Moreover, it is relevant to report meal related plasma concentrations of these hormones in persons with obesity given the growing interest in their pharmacological potential in obesity therapy. We find it clinically relevant to examine associations between the SNP rs9939609 genotypes and homeostatic appetite regulation in individuals with BMI ≥35 kg/m2.

Dietary protein reduces energy intake in following meals by signaling directly or indirectly to the brain. We recently observed differences in plasma amino acid kinetics and intra-gastric behavior between micellar casein (MC) and sodium caseinate (SC) in pigs, two factors that impact food intake. Our objective was to clarify whether the supramolecular structure of casein, given as a preload to pigs, impacts on subsequent food intake.

A similar secretory pattern of prolactin (PRL) and growth hormone (GH) during the menstrual cycle has been reported in response to a high dose of ghrelin in adult healthy women. The present study aimed to assess the pattern of PRL and GH secretions in response to a submaximal dose of ghrelin during different menstrual phases in adult healthy women. Eight female subjects with normal cyclicity were enrolled.
