Özet

The aim of this study was to investigate the methylation of the SFRP2, P16, DAPK1, HIC1, and MGMT genes, as well as the mutation of amino acid codons 12 and 13 of the KRAS gene in normal and tumor tissue DNA of patients diagnosed with sporadic colorectal cancer (SCRC). The methylation of gene regions and the KRAS mutations of normal (N) and tumor tissue (T) DNA obtained from 17 patients diagnosed with SCRC and 20 healthy controls were investigated using the polymerase chain reaction and reverse-hybridization methods. There was an Asp mutation in four patients, an Asp and Ser mutations in one patient in codon 12 of the KRAS gene, and an Asp mutation in codon 13 in eight patients. Overall promoter methylation (OPM) in the SFRP2 gene was observed in one N and four T, whereas partial promoter methylation (PPM) was observed in two N and five T. OPM in the P16 gene was present in one T. In the DAPK1 gene, OPM existed in seven T and five N, while PPM was present in two N. In the HIC1 gene, OPM was demonstrated in three T, while PPM was noted in two N; however, no methylation existed in N. In the MGMT gene, OPM occurred in five T and two N, and PPM was present in one T. KRAS mutations in Turkish patients with SCRC are similar to those of other population groups. Methylations in the genes, which underwent methylation analysis, were higher in Tin comparison with N, and it has been suggested that significant results would be obtained by making a study with a larger population.
