Abstract:
Objective:To study the relationship between circulating inflammatory proteins and liver cancer by Mendelian randomization.Methods:Data from the genome-wide association study (GWAS) of 91 circulating inflammatory proteins were sourced from the GWAS Catalog, involving 14 824 participants of European ancestry from 11 cohorts. Summary statistics for liver cancer were obtained from the GWAS database, encompassing a total sample of 197 611 cases, a two-sample Mendelian randomization analysis was conducted to evaluate the relationship between 91 circulating inflammatory proteins and liver cancer. Among them, inverse variance weighting, weighted median method, MR-Egger, simple mode, and weighted mode were the main analysis methods. Using odds ratio (OR) values to evaluate the causal relationship between them. Cochran Q-test, MR-PRESSO, MR-Egger intercept, and "leave-one-out" analyses were used for sensitivity analysis. Reverse MR, MR-Steiger tests were employed to rule out the influence of reverse causality.Results:Among the circulating 91 inflammatory proteins, C-C motif chemokine 20 ( OR=1.28, 95% CI: 1.01-1.62), CD40 receptor ( OR=1.31, 95% CI: 1.00-1.28), fibroblast growth factor 21 ( OR=1.47, 95% CI: 1.18-1.83), glial cell line-derived neurotrophic factor ( OR=1.29, 95% CI: 1.08-1.54), interleukin-13 (IL-13) ( OR=1.24, 95% CI: 1.02-1.50), IL-20 levels ( OR=1.78, 95% CI: 1.30-2.44), IL-20 receptor subunit alpha ( OR=1.43, 95% CI: 1.06-1.93), and matrix metalloproteinase-10 ( OR=1.21, 95% CI: 1.04-1.39) have positive causal relationship with the occurrence of liver cancer. And IL-1 alpha ( OR=0.83, 95% CI: 0.71-0.96), IL-24 ( OR=0.68, 95% CI: 0.47-0.99), leukemia inhibitory factor ( OR=0.77, 95% CI: 0.60-0.98) and stem cell factor ( OR=0.87, 95% CI: 0.78-0.97) showed negative causal relationship with the occurrence of liver cancer. Heterogeneity tests for all 12 circulating inflammatory proteins revealed no outliers. Sensitivity analyses consistently demonstrated robustness, with no evidence of pleiotropy observed. Neither reverse MR nor MR-Steiger tests supported the existence of a reverse causal relationship between inflammatory proteins and liver cancer. Conclusion:The C-C motif chemokine 20, CD40L receptor, fibroblast growth factor 21, glial cell line-derived neurotrophic factor, IL-13, IL-20, IL-20 receptor subunit alpha, MMP-10, IL-1 alpha, IL-24, leukemia inhibitory factor, and stem cell factor may be causally related to the development of liver cancer.
