| Background: An association between lung cancer and chemokines has been advocated in the recent years. This study aims at investigating the association between lung cancer and 16C/A single nucleotide polymorphism (SNP) (rs. 4359426) in C-C motif chemokine 22 (CCL22) as well as C1014T SNP (rs. 2228428) in C-C chemokine receptor type 4 (CCR4), which serves as the receptor for CCL22.Methods: Genotyping was performed in 148 lung cancer patients and 148 normal controls using Polymerase Chain Reaction-Restriction-Fragment Length Polymorphism (PCR-RFLP). The data were verified by direct automated sequencing. Results: Frequencies of CC, CA and AA genotypes of 16C/A SNP in CCL22 gene were 112 (75.7%), 33 (22.3%) and 3 (2.0%) in patients, and 119 (80.4%), 24 (16.2%) and 5 (3.4%) in controls respectively. No significant differences were observed in genotype frequencies at this position between cases and controls (P=0.34). Moreover, there was no significant association between CCL22 polymorphism and types of lung cancer in patients. The distribution of CC, CT and TT genotypes of C1014T SNP in CCR4 gene, was 76 (51.4%), 60 (40.5%) and 12 (8.1%) in patients, and 80 (54.1%), 49 (33.1%) and 19 (12.8%) in controls respectively. No statistically significant differences were observed in genotypes frequencies of CCR4 gene between patients and controls (P=0.24). The genotype inherited by patients observed not to be associated with the type of lung cancer (P>0.05).Conclusion: Results reveal that CCL22 gene polymorphism at position 16C/A and CCR4 gene polymorphism at position C1014T, appear not to be associated with susceptibility to lung cancer. | ||
