Distribution of Obestatin and Ghrelin in Human Tissues

Ghrelin and obestatin in human neuroendocrine tumors: expression and effect on obestatin levels after food intake.

BACKGROUND Ghrelin and obestatin are derived from the same peptide hormone precursor and are mainly produced by the gastric mucosa. Ghrelin is involved in many biological processes, whereas the physiological function of obestatin needs further investigation. The aims of the present study were to establish the incidence of ghrelin- and obestatin-immunoreactive cells in a comprehensive panel of h...

Ghrelin, Obestatin and Leptin in Childhood Obesity

Effects of Combined Training on the Levels of Obestatin, Ghrelin, and Insulin Resistance in Overweight Women

Background: The present quasi-experimental and field research was conducted to evaluate the effect of combined exercises on the levels of obestatin and ghrelin in overweight women. Methods: The study subjects consisted of 34 overweight women with a Mean±SD age of 30.29±4.66 years, a Mean±SD height of 165.11±5.56 cm, a Mean±SD weight of 74.64±7.33 kg, a Mean±SD body mass index of 27.35±1.74 kg/...

Ghrelin and obestatin: different role in fetal lung development?

Ghrelin and obestatin are two proteins that originate from post-translational processing of the preproghrelin peptide. Various authors claim an opposed role of ghrelin and obestatin in several systems. Preproghrelin mRNA is significantly expressed in airway epithelium throughout lung development, predominantly during the earliest stages. The aim of this study was to evaluate the role of ghrelin...

Immunohistochemical Localization of Ghrelin in Testicular Tissues of Holstein Bulls

Ghrelin, a 28-amino acid acylated peptide, was identified as the endogenous ligand for the growth hormone (GH) secretagogue receptor and its role in reproduction has recently been established. It is believed that the site of ghrelin expression in testes may indicate its role in local regulation. This study investigated the immunohistochemical (IHC) localization of ghrelin in Holstein bull testi...
