Upregulation of HOTAIR Transcript Level in Tumor Tissue of Iranian Women with Breast Cancer
Background:Dysregulation of HOX Transcript Antisense Intergenic RNA (HOTAIR) has been linked to the etiopathogenesis of several human cancers. According to epidemiological evidences, the risk of susceptibility to breast cancer varies among different populations. This study was designed to determine the transcriptional level of HOTAIR in tumor cells of breast cancer pat...
متن کاملCorrelation of Tissue Distribution of HLA-G and HLA-E and Degree of Tumor Malignancy in Patients with Breast Cancer
Background and Aims: Human leukocyte antigen (HLA) molecules play a substantial role in T Lymphocyte-mediated adaptive immune response. Down-regulation of HLA expression may help the tumor to escape from immune surveillance. This study aimed to evaluate the correlation between HLA-G and HLA-E tissue distribution and the degree of tumor malignancy in human breast tumors. Materials and Methods:...

Background: Breast cancer is the second most common cancer in the world after lung cancer also is the fifth cause of cancer mortality. About 90 percent of cancer mortality is because of metastasis and devastating between cell attachments, especially tight cell junctions. Epithelial mesenchymal transition is a phenomena involved in metastasis and starts with cell detachment. Occludin is the inte...

متن کاملRole of Cyclooxygenese-2 (COX-2) Expression in Breast Cancer Differentiation and Its Relationship with Hormone Receptors Status
Background and Objectives: Cyclooxygenese-2 (COX-2) expression in breast cancer and its correlation with tumor prognosis is unclear. We investigated the incidence of COX-2 expression in patients and assessed interactions between COX-2 and clinical features of cancer and expression of HER2/neu, estrogen receptor (ER), and progesterone receptor (PR). Methods: COX-2 expression was investigated by...
متن کاملStudy of the Expression of miR-4270 in Plasma of Patients with Breast Invasive Ductal Carcinoma
Detection of tumor-specific microRNAs (miRs) in the blood of cancer patients may provide a unique and valuable biomarker for diagnosis and prognosis. The aim of this study was to investigate whether plasma levels of microRNA-4270 could serve as a potential marker for breast invasive ductal carcinoma. A total of 40 breast cancer patients and 28 controls were recruited in this study. Total RNA wa...
