Introduction: Obesity and insulin resistance have been identified as risk factors for breast cancer and are associated with late-stage diagnosis and poor prognosis. Ghrelin is a unique gut-derived peptide that has major impact in energy homeostasis and weight regulation, with new emerging implications in tumorigenesis process, especially in hormone-dependent cancers.Aim: To evaluate the relationship between ghrelin, clinico-biological parameters of obesi...

Experimental autoimmune thyroiditis (EAT) has been used to simulate human autoimmune thyroid disease for decades. EAT can be easily induced in genetically susceptible strains of mice by excess iodine ingestion or by immunization with mouse thyroglobulin. Excess iodine may induce and exacerbate autoimmune thyroiditis (AIT) in humans and animal models. In order to assess the potential protective mechanisms of selenium (Se) in thyroid autoimmunity, we evaluated the effects of ino...

Introduction: Ghrelin, a peptide hormone produced in the stomach, stimulates secretion of growth hormone and regulates appetite and energy homeostasis. Various other effects attributed to ghrelin may contribute to many aspects of cancer development and progression.Material and Methods: Using polyclonal antibody immunohistochemistry, we assessed (by intensity scoring) the immunolocalization of ghrelin in 70 tissue samples, and described particularities wi...
