Background: Endometriosis, a gyncological disorder,benign and common cause of infertility, is defined as the presence of endometrial glands and stroma at ectopic locations outside the uterine cavity. Clinical observations have led to the assessment that endometriosis is an invasive disease. Abnormal expression of adhesion molecules such as cadherins is likely to be an important determinant of l...

introduction: colorectal carcinoma is a main health problem in many countries and the third common cancer in iran. this malignancy at present is the most curable carcinoma of gastrointestinal tract. variation in the expression of the proteins produced by p53, p21, p16, e-cadherin, and β-catenin genes have been noted in this malignancy and may be important in the prognosis and therapeutic respon...

background : e-cadherin is a trans-membrane glycoprotein that plays a critical role in many aspects of cell adhesion as well as establishment and maintenance of epithelial cell polarity. loss of the adhesive function of e-cadherin seems to promote invasive and metastatic properties of neoplastic cells.   objectives: the present study is a retrospective study aiming to evaluate the loss of e-cad...

Background and objectives:  Gastric cancer is currently known as one of the most important causes of cancer-driven death all over the world. In patients with gastric cancer, a significant proportion of death occurs due to metastasis. On the other hand, down modulated E-cadherin level has been reported as an important contributor to tumor cell invasion and metastasis. In this re...

conclusions according to this observation, another factor such as oncogenes activity may cause cancer in samples but ct genotype of mthfr can be considered as an effective factor in creating cancer. results methylation status of e-cadherin gene numbers of methylated cases in the cancer group were equal to one and unmethylated cases equal to 33 and numbers of unmethylated cases in the non-cancer...

Loss of expression of the E-cadherin cell-cell adhesion molecule is important in carcinoma development and progression. Because previous data suggest that loss of E-cadherin expression in breast carcinoma may result from a dominant transcriptional repression pathway acting on the E-cadherin proximal promoter, we pursued studies of cis sequences and transcription factors regulating E-cadherin ex...

background gastric dysplasia (gd) is a precursor lesion of gastric adenoâ­carcinoma. intestinal type gastric carcinoma commonly shows microsatellite instability (msi) and the diffuse type is associâ­ated with down regulation of e-cadherin. her-2/neu is over-expressed in some cases of gastric cancer. in this study, msi and expression rates of her-2/neu and e-cadherin in gd were evaluated. me t h...

The degree of E- and P-cadherin expressions inversely correlate with the progression stage of human melanoma. In the present study, we analyzed mechanisms of down-regulation of E- and P-cadherin gene expressions in 8 human melanoma cell lines. In 5 of the 8 melanoma cell lines, E-cadherin expression was lost or markedly decreased compared to that in normal melanocytes, and 4 of the 5 melanoma c...
