[PMID: 31075410 DOI: 10.1016/j.gene.2019.05.011] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2018] [Revised: 04/24/2019] [Accepted: 05/06/2019] [Indexed: 01/16/2023]
Abstract
BACKGROUND Pulmonary tuberculosis caused by an intracellular pathogen, Mycobacterium tuberculosis continues to exist as a hazardous disease to human life globally. Genetic polymorphisms regulate resistance and susceptibility to tuberculosis. The C-type lectin receptor of family 4 member E (CLEC4E) confers protection against tuberculosis in laboratory animals but its function in influencing exposure or resistance to pulmonary tuberculosis (PTB) in humans remains obscure. AIM We conducted this research to analyze the effects or concomitance of CLEC4E gene variations with susceptibility to pulmonary tuberculosis in a northern Chinese population. METHOD In this study, 202 participants with pulmonary tuberculosis and 214 controls without PTB were enrolled. Two single nucleotide polymorphisms (SNPs) for CLEC4E on chromosome 12 were selected with a minor allele frequency of >0.05. All the SNPs were genotyped using high resolution melting analysis-PCR. RESULTS We estimated and compared two SNPs, rs10841845 and rs10841847. From our study findings, CLEC4E rs10841845 conferred protection against the development of pulmonary TB with a P value of <0.05 and odds ratio of <1 for all models of genetic inheritance. CLEC4E rs10841847 genotypes in co-dominant, Recessive, Dominant models and alleles had a significant statistical difference between patients and controls associated with resistance against the development of PTB (P<0.05 and OR<1). CONCLUSION Our findings suggest that variations at rs10841845 and rs10841847 of CLEC4E genes are associated with increased individual protection against PTB.

Abstract
Background The gene polymorphism of interleukin-6 (IL-6) has been shown to be implicated in tuberculosis susceptibility in many studies, but with conflicting results. This study aimed to provide more accurate estimation of the relationship between IL-6 gene polymorphism and tuberculosis risk through a meta-analysis. Method A literature search was performed in PubMed, EMBASE, and other databases. Data were retrieved, and pooled odds ratio (OR) with 95% CI were calculated. Statistical analyses were performed by using STATA 12.0. Results Twelve publications with 2635 cases and 3049 controls were included. The pooled analysis demonstrated significant evidence of association between IL-6 (-174G/C) and low risk of tuberculosis in dominant model (CC+GC vs GG: OR =0.693, 95% CI 0.581-0.826, p<0.001). Subgroup analysis got similar results for IL-6 (-174G/C) in Asians and Latinos, but the significance did not exist in Caucasians. IL-6 (-572C/G) polymorphism was also associated with low risk of tuberculosis in dominant model (CC+GC vs GG: OR =0.719, 95% CI 0.577-0.896, p=0.003). No publication bias was detected in either of the polymorphisms. Conclusion In summary, IL-6 -572 C/G polymorphism may be associated with a decreased risk of tuberculosis, and C allele is the protective factor against tuberculosis for IL-6 -174G/C among Asians and Latinos, but not in Caucasian population.

Characterization of plasma proteins in children of different Mycobacterium tuberculosis infection status using label-free quantitative proteomics. Oncotarget 2017; 8:103290-103301.

Abstract
Tuberculosis (TB), caused by Mycobacterium tuberculosis (MTB), is an infectious disease found worldwide. Children infected with MTB are more likely to progress to active TB (ATB); however, the molecular mechanism behind this process has long been a mystery. We employed the label-free quantitative proteomic technology to identify and characterize differences in plasma proteins between ATB and latent TB infection (LTBI) in children. To detect differences that are indicative of MTB infection, we first selected proteins whose expressions were markedly different between the ATB and LTBI groups and the control groups (inflammatory disease control (IDC) and healthy control (HC) groups). A total of 521 proteins differed (> 1.5-fold or < 0.6-fold) in the LTBI group, and 318 proteins in the ATB group when compared with the control groups. Of these, 49 overlapping proteins were differentially expressed between LTBI and ATB. Gene Ontology (GO) analysis revealed most proteins had a cellular and organelle distribution. The MTB infection status was mainly related to differences in binding, cellular and metabolic processes. XRCC4, PCF11, SEMA4A and ATP11A were selected and further verified by qPCR and western blot. At the mRNA level, the expression of XRCC4, PCF11and SEMA4A presented an increased trend in ATB group compare with LTBI. At the protein level, the expression of all these proteins by western blot in ATB/LTBI was consistent with the trends from proteomic detection. Our results provide important data for future mechanism studies and biomarker selection for MTB infection in children.

Association of interleukin-6 gene polymorphism (rs1800796) with severity and functional status of osteoarthritis in elderly individuals. Cytokine 2015; 75:316-20. [PMID: 26233477 DOI: 10.1016/j.cyto.2015.07.020] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2014] [Revised: 07/20/2015] [Accepted: 07/22/2015] [Indexed: 11/21/2022]
Abstract
Osteoarthritis (OA) is the most prevalent disease of the musculoskeletal system and it has an important genetic component. Despite several reports have shown the involvement of pro-inflammatory cytokine such as interleukin-1β and TNF-α, the role of interleukin-6 (IL-6) in osteoarthritis is still unclear. Thus, this study aimed to analyze the relationship between the single nucleotide polymorphism in the portion -572 of the promoter region of the IL6 gene (SNP -572G/C) with hip and knee OA in the elderly. In this case-control study, 257 physically independent elderly were recruited (case group: 92 individuals with osteoarthritis and control group: 165 individuals with no osteoarthritis). Blood samples were collected from patients for the DNA fragments extraction and amplification by real-time polymerase chain reaction (PCR) by TaqMan system for subsequent genotyping of IL6 gene. The degree of joint damage was assessed by radiographic classification based on the criteria of Kellgren and Lawrence. The functional status was evaluated by Lequesne and WOMAC questionnaires. It was observed that individuals carrying the C allele have lower susceptibility to osteoarthritis (OR=0.51, 95% CI: 0.32-0.80, p=0.004) and less radiological impairment for both hip (Fisher-Freeman-Halton test=4.2 and p=0.04) and knee joints (Fisher-Freeman-Halton test=4.7 and p=0.03). Regarding functional status, individuals carrying the C allele has a lower degree of functional impairment assessed by WOMAC (Mann-Whitney test, p=0.04), although no difference was observed in the Lequesne questionnaire (p>0.05). Additionally, it was observed a marked reduction in IL-6 serum levels in individuals with GC and CC genotypes when compared to individuals harboring GG genotype. In conclusion, the polymorphism -572G/C IL6 is a protective factor for the presence and severity of hip and knee osteoarthritis in the elderly. Further prospective studies with large sample size and methods (e.g. effect of this polymorphism on gene expression, haplotype analysis for IL-6 promoter polymorphism) are needed to validate this study findings.
