Background, Programed cell death 1 (PD-1) and its ligand (PD-L1) activity have already detected in various cancers. In non-Hodgkin lymphoma (NHL), however, the prognostic value of PD-1/PD-L1 genes polymorphisms and expression levels remains unclear. In the present study we aimed to investigate the relationship between genetic polymorphisms of PD-1/PD-L1 genes and non-Hodgkin lymphoma in Iranian papulation.
Methods, four single nucleotide polymorphisms of the PD-1/PD-L1 genes, including 134 NHL patients and 125 healthy controls were examined using PCR-RFLP method. The expression level of PD-1/PD-L1 genes were analyzed using real time PCR method.
Results, our data demonstrated that the PD-L1 rs2890685 (A>C) SNP (p<0.0001) significantly was associated with increased risk of NHL. The AA genotype of PD-L1 rs2890685 polymorphism was found to be more prevalent in NHL patents compared to healthy controls. No significant association were found between PD-L1 rs4143815, PD-1 rs11568821, PD-1rs2227981 SNPs and the risk of NHL incidence. Furthermore, our data showed that the mRNA transcription levels of both PD-1 and PD-L1 were significantly higher than normal healthy controls (p<0.001).
Conclusion, Collectively, our finding demonstrated that the functional PD-L1 rs2890685 polymorphism was associated with NHL risk, suggesting that genetic variant of PD-L1 might be a possible prognosis marker for prediction of NHL risk and its development.
