Examination of the expression levels of MACC1, Filamin A and FBXW7 genes in colorectal cancer patients.

Abstract

OBJECTIVE:Colorectal cancer (CRC) is the third most common type of cancer observed in cancer-related mortality because it has a high metastasis ratio. This study aims to investigate the expression levels of several genes, including metastasis-related colon cancer 1 (MACC1), Filamin A (FLNA), F-box/WD repeat-containing protein 7 (FBXW7), which has an important role in cell signaling, migration and adhesion through the remodeling of the cell skeleton.METHODS:In this study, 21 patients with a precise diagnosis of CRC and 21 controls were included. Gene expressions were examined using the RT-PCR technique. To define the relationship of the genes with metastasis, blood samples were collected from all patients with colon/rectal cancer diagnosis without metastasis at six months before and after the medication with Xelox.RESULTS:Our findings showed that no significant difference was observed in the pre-treatment values compared to the control group, whereas FLNA (p=0.001) expression was observed to be significantly increased following treatment with Xelox.CONCLUSION:To our knowledge, our study is the first study to investigate the effects of Xelox treatment on the expression levels of MACC1, FBXW7 and FLNA genes in non-metastatic colorectal cancer patients in Turkey.
