IL-17F gene polymorphism is associated with susceptibility to acute myeloid leukemia.

ABSTRACT:

Purpose

Recent studies have suggested that Th17 cells may play a role in the pathogenesis of acute myeloid leukemia (AML). This subset of CD4+ cells is characterized by interleukin (IL)-17A and IL-17F production, which share strong homology, and surface expression of the IL-23 receptor (IL-23R). The present study aimed to determine the association between the polymorphic features located within the IL-17A, IL-17F and IL-23R genes and disease susceptibility, progression and response to therapy. In addition, the relationship between the polymorphic variants and the plasma IL-17 levels in patients was analyzed.

Methods

For this purpose, 187 individuals of Polish origin including 62 AML patients and 125 healthy controls were typed for IL-17A (rs2275913; G-197A), IL-17F (rs763780; A7488G; His161Arg) and IL-23R (rs11209026, G1142A; Arg381Gln) alleles.

Results

The rs763780 IL-17F polymorphism appeared to be associated with susceptibility to the disease. The presence of the minor (G) variant (RR = 4.76, p < 0.001) and its homozygosity (RR = 23.02, p < 0.005) was more frequent among patients than healthy individuals. No significant association was observed for either other polymorphisms studied or IL-17 levels.

Conclusions

Thus, the rs763780 IL-17F polymorphism was found to be associated with predisposition to AML in the Polish population.

Project description:PurposeAlthough MYBL2 had been validated to participate in multiple cancers including leukemia, the role of MYBL2 polymorphisms in acute lymphoblastic leukemia (ALL) was still not clear. In this study, we aimed to evaluate the association between MYBL2 single nucleotide polymorphisms (SNPs) and ALL risk in children.MethodsA total of 687 pediatric ALL cases and 971 cancer-free controls from two hospitals in South China were recruited. A case-control study by genotyping three SNPs in the MYBL2 gene (rs285162 C>T, rs285207 A>C, and rs2070235 A>G) was conducted. The associations were assessed by odds ratios (ORs) with corresponding 95% confidence intervals (CIs). Subgroup and stratification analyses were conducted to explore the association of rs285207 with ALL risk in terms of age, sex, immunophenotype, risk level, and other clinical characteristics. The false-positive report probability (FPRP) analysis was performed to verify each significant finding. Functional analysis in silico was used to evaluate the probability that rs285207 might influence the regulation of MYBL2 .ResultsOur study demonstrated that rs285207 was related to a decreased ALL risk (adjusted OR = 0.78; 95% CI = 0.63-0.97, P = 0.022) in the dominant model. The associations of rs285207 with ALL risk appeared stronger in patients with pre B ALL (adjusted OR=0.56; 95% CI=0.38-0.84, P=0.004), with normal diploid (adjusted OR=0.73; 95% CI=0.57-0.95, P=0.017), with low risk (adjusted OR=0.68; 95% CI=0.49-0.94, P=0.021), with lower WBC (adjusted OR=0.62; 95% CI=0.43-0.87, P=0.007) or lower platelet level (adjusted OR=0.76; 95% CI=0.59-0.96, P=0.023). With FPRP analysis, the significant association between the rs285207 polymorphism and decreased ALL risk was still noteworthy (FPRP=0.128). Functional analysis showed that IKZF1 bound to DNA motif overlapping rs285207 and had a higher preference for the risk allele A. As for rs285162 C>T and rs2070235 A>G, no significant was found between them and ALL risk.ConclusionIn this study, we revealed that rs285207 polymorphism decreased the ALL risk in children, and rs285207 might alter the binding to IKZF1, which indicated that the MYBL2 gene polymorphism might be a potential biomarker of childhood ALL.
