Investigation of ARF6 gene expression in colorectal cancer

Colorectal cancer is one of the most common cancers in the world. Colorectal cancer develops after a long and multistep carcinogenesis process. Adenosine diphosphate-ribosylation factors (ARFs) are a family of Ras-related GTP binding proteins. ARF6 functions are concerned with actin cytoskeletal remodeling, cell polarity and cell migration and thus may have an important role in driving carcinogenesis. In many types of cancer such as breast, lung, brain and skin, ARF6 has been associated with these cancer types. This study aims to clarify the relationship between the level of ARF6 expression and tumor and normal colon / rectum tissues of colorectal cancer patients in Turkish community. Ethics committee approval required for the study was obtained from the Gaziantep University Medical Faculty Local Ethics Committee. Normal and tumor tissue samples were obtained from 43 patients with colorectal cancer. ARF6 mRNA expressions were analyzed by real time-PCR. Results of the study show that there was no statistically significant difference between ARF6 expression levels in normal and tumor tissues (p > 0.05).
