Background and purpose: Colorectal cancer (CRC) is one of the most common types of cancer. Its incidence has increased in Iran during the last 25 years. Micro-RNAs are used as new approach in cancer researches. The roles of miR-146a have been detected in different tumors. This study aimed at investigating the expression of microRNA146 in tumor tissue of colorectal adenocarcinoma in various stag...

Introduction: Studies have shown that an increase in carcinoembryonic antigen (CEA) is associated with the progression of colorectal cancer and is considered a sensitive diagnostic factor for CRC. Moreover, the role of peroxisome proliferators (PPARs) has recently been considered in colorectal cancer. This study aimed to investigate the relationship between the expression level of PPARs and CEA...

Hypermethylation of CpG islands located in the promoter regions of genes is a major event in the development of the majority of cancer types, due to the subsequent aberrant silencing of important tumor suppressor genes. KLOTHO; a novel gene associated primarily with suppressing senescence has been shown to contribute to tumorigenesis as a result of its impaired function. Recently the relevance ...

introduction: insertion or deletion of a guanine in -1607 at promoter region of matrix metalloproteinase-1 enzyme creates two allelic types for this gene in the population: 2g and 1g, respectively. 2g allele contains an extra binding site for ets transcription factors that this may increase the level of gene expression. therefore, aim of this study was investigation of the single guanine insert...

Background and Purpose: Each year, about 50,000 new cases of cancer occur in Iran and the most common being the gastrointestinal (GI) tract (38%). Colorectal cancers account for the 3rd and 4th most prevalent cancers in Iranian men and women, respectively. Since genetic and environmental factors lead to differences in colorectal cancer occurrence in different geographic regions and races, we ...

Background: Colorectal cancer is the third most common type of aggressive cancers. Chemotherapy, surgery,and radiotherapy are the common therapeutic options for treating this cancer. Due to the adverse side-eff ects of these methods, immunotherapy is considered as an appropriate alternative therapeutic option. Treatment through the application of monoclonal antibodies is considered as a n...
