BACKGROUND: As a definition, Endometriosis is a commonly encountered gynecological disease; as endometrial glandular and stromal cells existing in the outside of the uterus. In spite of several studies on endometriosis, its molecular mechanism and pathogenesis nevertheless have been not completely illuminated. Role of ELAM-1 gene in mediating the adhesion of tumor cells to endothelial cells by binding to ELAM-1 ligands expressed by eosinophils, neutrophils, monocytes, natural killer cell effectors T-lymphocyte cell, and cancer (progenitor/stem) cells is well studied. Our hypothesis proposes that the alteration in ELAM-1 mRNA level is a significant point in successful transplantation deregulations of effective migration genes which may be related to endometrial proliferative disorders such as endometriosis.
METHODS: In this study, Real time-PCR, Western blotting and immunohistochemistry has been applied in order to determine the expression pattern of ELAM-1 gene in 22 patients. for the validation study, control group include 8 healthy wemon were recruited. Comparison of the prognostic accuracy of Elam-1 with other clinicopathological risk factors were analyzed by logistic regression.
RESULTS: The endometriosis tissues from women ages 33 ± 7 years (mean, [±SEM]) were assessed. The results showed that the ELAM-1 mRNA expression is significantly higher in patients group compare control group (p=0.0001). Moreover, in the samples of Stage III and IV, ELAM-1 gene has expressed more (p<0.001). ELAM-1 immunostaining expressed positive staining in the patients group. ELAM-1 protein expression level was correlated directly with American Fertility Society score and depicted no correlation with age.
CONCLUSIONS: According to our results, ELAM-1 upregulation may promote disorder in adhesion, and migration of the cells leading to the endometriosis disorder.
