摘要：

ContextAdrenal tumours belong to one of the most prevalent neoplasms. It is a heterogeneous group with different aetiology, clinical manifestation and prognosis. Its histopathologic diagnosis is difficult and identification of differentiation markers for tumorigenesis is extremely valuable for diagnosis. DesignTo assess ghrelin expression and the relationship among ghrelin, IGF2 and the clinicopathological characteristics of adrenal tumours. To investigate the influence of ghrelin on ACC cell line proliferation. Materials and methodsExpression of ghrelin and IGF2 in a total of 84 adrenal tissue samples (30 adenoma, 12 hyperplasia, 8 myelolipoma, 20 pheochromocytoma, 7 carcinoma and 7 unchanged adrenal glands) were estimated. Every operated patient from whom samples were obtained underwent clinicopathological analysis. All the parameters were compared among the groups examined and correlations between these were estimated. H295R cell line was incubated with ghrelin to assess its effect on proliferation and migration rate. ResultsThe highest ghrelin expression was observed in carcinoma samples and the lowest in the control group. Ghrelin expression was 21 times higher in carcinoma (P=.017) and 2.4 times higher in adenoma (P=.029) compared with controls. There were no statistically significant differences between myelolipoma (P=.093) and pheochromocytoma (P=.204) relative to the control. Ghrelin level was significantly higher in carcinoma compared to adenoma (P=.049) samples. A positive correlation between ghrelin and IGF2 expression was observed only in myelolipoma (P=.001). Ghrelin at concentrations of 1x10(-6)mol/L and 1x10(-8)mol/L significantly stimulated proliferation and migration rate in the H295R cell line. ConclusionGhrelin appears to be an essential factor in driving adrenal tumours development.
