The effect of Paraoxonase gene polymorphisms and paraoxonase enzyme activity on Non-Hodgkin lymphoma

İngilizce (OpenAlex)

Non-Hodgkin Lymphoma (NHL) is a malignant lymphoproliferative disease. Antioxidant paraoxonase enzyme (PON1) has a vital role in the elimination of potential carcinogenic organophosphate molecules. The polymorphisms in the PON1 gene, especially Q192R and L55M, may affect negatively the activity and synthesis of PON1 enzyme. The aim of this study was to evaluate the effect of these polymorphisms together with PON1 enzyme activity on NHL. We surveyed these polymorphisms together with PON1 enzyme activity in 93 patients with NHL and in 93 healthy individuals by real-time polymerase chain reaction (RT-PCR) and spectrophotometer. Although carrying the M and R alleles of L55M and Q192R polymorphisms increases the risk of NHL, they were not significant. Furthermore, the NHL patients carrying 192 R allele had significantly lower enzyme activity than controls having same allele (P = 0.025). This research is the first study worldwide investigating the effect of Q192R and L55M polymorphisms on PON1 enzyme activity in NHL disease. The risk of developing NHL may be further increased in individuals with low enzyme activity having R risk allele of the Q192R polymorphism. The present study suggests that these polymorphisms in NHL disease should be analyzed together with PON1 enzyme activity in larger populations.Supplemental data for this article is available online at https://doi.org/10.1080/15257770.2022.2052315 .
