Association between IL1B gene and cervical cancer susceptibility in Chinese Uygur Population: A Case–Control study

Background Interleukin‐1β (IL‐1B) has been recognized as a pro‐inflammatory cytokine and associated with tumorigenesis. We aimed to evaluate the contribution of IL‐1B polymorphisms to the susceptibility of cervical cancer in Chinese Uygur population. Methods Seven variants were genotyped by Agena MassARRAY platform in 267 cervical cancer patients and 302 healthy controls. Allelic, genotypic, and haplotypic association analyses adjusted for age were investigated using odds ratios (OR) and 95% confidence intervals (CI). GEPIA and UALCAN databases were used to evaluate expression and prognostic of IL‐1B gene in cervical cancer. Results Our result revealed IL‐1B rs1143627‐AA (OR = 1.98, p = 0.029) and rs16944‐GG (OR = 2.01, p = 0.025) was associated with an increased risk of cervical cancer. Besides, we also found two protective single nucleotide polymorphisms (SNPs) rs3136558 (OR = 0.63, p = 0.011) and rs1143630 (OR = 0.63, p = 0.019). Haplotype ″TGA″ in the block (rs1143630, rs1143627, and rs16944) significantly decreased the susceptibility of cervical cancer (OR = 0.53, p = 0.0007). IL‐1B mRNA level was up‐regulated in the cervical cancer patients, which was related with poor prognosis in silico. Conclusions For the first time, our results provide evidence on polymorphism of IL‐1B gene associated with cervical cancer risk in Chinese Uygur population.
