| Description | Adiponectin is a recently described protein secreted by adipocytes, whose circulating levels are reduced in conditions related to insulin resistance and hyperinsulinemia. Leptin is small peptide produced by adipocytes and is implicated in a great number of endocrine regulations, whose impairment might result in obesity. The aim of this study was to investigate possible associations of previously described polymorphisms within the leptin (LEP -2548 G/A) and adiponectin gene (T94G) and development of endometrial cancer. Methods: Peripherial blood samples obtained of 16 women with endometrial cancer and 14 healthy controls were evaluated for leptin -2548 G/A and adiponectin T94G polymorphisms. Results: We did not found any significant differences in genotype distributions and allelic frequencies of both examined polymorphims (LEP -2548 G/A: pg=0.13 and Adipo T94G: pg=0.75) in endometrial cancer cases and controls. The endometrial cancer cases differed significantly from the controls in baseline patients characteristics, such as weight (p= < 0.0001), height (p= < 0.0001), LDL cholesterol plasma level (p=0.02) and spontaneous abortion rate (p=0.0006). Conclusions: Our results do not clearly support the hypothesis for leptin and adiponectin polymorphisms involvement in ethiopathogenesis of endometrial cancer. However, as this was a preliminary study, the number of cases in both cohorts might not be sufficient for finding a significant association. |
