The Relationship between Metabolic Syndrome and Plasma Metals Modified by EGFR and TNF-α Gene Polymorphisms.

ABSTRACT: With the escalating global prevalence of metabolic syndrome (MetS), it is crucial to detect the high-risk population early and to prevent chronic diseases. Exposure to various metals has been indicated to promote MetS, but the findings were controversial, and the effect of genetic modification was not considered. Epidermal growth factor receptor (EGFR) was proposed to be involved in the pathway of metabolic disorders, and tumor necrotic factor-α (TNF-α) was regarded as an early inflammatory biomarker for MetS. This research aimed to analyze the impact of EGFR and TNF-α gene polymorphisms on the prevalence of MetS under environmental or occupational exposure to metals. We gathered data from 376 metal industrial workers and 639 non-metal workers, including physical parameters, biochemical data, and plasma concentrations of six metals. According to the genomic database of Taiwan Biobank, 23 single nucleotide polymorphisms (SNPs) on EGFR gene and 6 SNPs on TNF-α gene were incorporated in our research. We applied multivariable logistic regression to analyze the probability of MetS with various SNPs and metals. Our study revealed some susceptible and protective EGFR and TNF-α genotypes under excessive exposure to cobalt, zinc, selenium, and lead. Thus, we remind the high-risk population of taking measures to prevent MetS.

Project description:The study explored the correlations of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) gene polymorphisms with susceptibility and the condition of primary nephrotic syndrome. A total of 200 patients with primary nephrotic syndrome in Qilu hospital were collected as disease group, and 200 healthy people were selected as control group. Genomic deoxyribonucleic acids (DNAs) of nucleated cells in the peripheral blood were extracted to detect the gene polymorphisms of TNF-α (rs1799724 and rs1800629) and IL-10 (rs1800872 and rs141219090). Allele distributions at rs1799724 (P=0.003) and rs1800629 (P=0.011) of TNF-α gene and at rs1800872 (P=0.033) of IL-10 gene in disease group were different from those in control group. In the disease group, allele C frequency at rs1799724 and allele A frequency at rs1800629 of TNF-α gene and allele T frequency at rs1800872 of IL-10 gene were higher. There were differences between rs1799724 (P=0.007) and rs1800629 (P=0.002) of TNF-α gene. In addition, there was a difference in the frequency of the dominant model of TNF-α gene rs1800629 between disease group and control group (P=0.035), and the frequency of dominant model GG+GA was remarkably lower in the disease group. Additionally, TT genotype at rs1799724 of TNF-α gene was obviously related to the plasma TNF-α level (P<0.05), and the plasma TNF-α level was significantly increased in disease group. AA genotype at rs141219090 of IL-10 gene had a notable correlation with the plasma IL-10 level (P<0.05), and the plasma IL-10 level in disease group was markedly raised. Additionally, CT genotype at rs1799724 of TNF-α gene was related to the 24-h urine protein level (P=0.035), GG genotype at rs1800872 of IL-10 gene was associated with the plasma albumin level (P=0.031), and GG genotype at rs141219090 was related to the serum creatinine level (P=0.047). TNF-α and IL-10 gene polymorphisms are predominantly correlated with the susceptibility and the condition of primary nephrotic syndrome.
