[PMID: 38308345 PMCID: PMC10835968 DOI: 10.1186/s13018-024-04583-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 01/25/2024] [Indexed: 02/04/2024] Open
Abstract
BACKGROUND Osteoarthritis (OA) is a degenerative joint disease caused by the deterioration of cartilage. However, the underlying mechanisms of OA pathogenesis remain elusive. METHODS Hub genes were screened by bioinformatics analysis based on the GSE114007 and GSE169077 datasets. The Sprague-Dawley (SD) rat model of OA was constructed by intra-articular injection of a mixture of papain and L-cysteine. Hematoxylin-eosin (HE) staining was used to detect pathological changes in OA rat models. Inflammatory cytokine levels in serum were measured employing the enzyme-linked immunosorbent assay (ELISA). The reverse transcription quantitative PCR (RT-qPCR) was implemented to assess the hub gene expressions in OA rat models. The roles of PDK4 and the mechanism regulating the PPAR pathway were evaluated through western blot, cell counting kit-8 (CCK-8), ELISA, and flow cytometry assays in C28/I2 chondrocytes induced by IL-1β. RESULTS Six hub genes were identified, of which COL1A1, POSTN, FAP, and CDH11 expressions were elevated, while PDK4 and ANGPTL4 were reduced in OA. Overexpression of PDK4 inhibited apoptosis, inflammatory cytokine levels (TNF-α, IL-8, and IL-6), and extracellular matrix (ECM) degradation protein expressions (MMP-3, MMP-13, and ADAMTS-4) in IL-1β-induced chondrocytes. Further investigation revealed that PDK4 promoted the expression of PPAR signaling pathway-related proteins: PPARA, PPARD, and ACSL1. Additionally, GW9662, an inhibitor of the PPAR pathway, significantly counteracted the inhibitory effect of PDK4 overexpression on IL-1β-induced chondrocytes. CONCLUSION PDK4 inhibits OA development by activating the PPAR pathway, which provides new insights into the OA management.

Abstract
Chronic cervical spondylitis (CCS), a degenerative disorder of the spine, is known for causing disability among old and young people. Single-nucleotide polymorphisms (SNPs) in various cytokine genes have demonstrated an impactful association with several inflammatory disorders. In the present study, we have investigated the SNPs and allelic distribution of the three most prevalent cytokines genes, IL-1β (-511C/T), TNF-α (-308G/A), and TGF-β (-509C/T), along with serum levels of these cytokines in 252 subjects. SNPs were analyzed using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and digested fragments were separated and visualized using agarose gel electrophoresis and Native Polyacrylamide gel electrophoresis (PAGE). The serum cytokine levels were analyzed with a flow cytometer using a customized multiplex bead-based assay. It was observed that these SNPs did not reflect the susceptibility to CCS but were associated with susceptibility to CCS. We found a significant association between the C/C and G/G genotypes and the C and G alleles of IL-1β and TNF-α, respectively, suggesting a lower risk of CCS. The frequency distribution of risk alleles (-511T) and (-308A) were simultaneously higher in CCS compared to the control, reflecting the susceptibility to CCS. TGF-β showed a significant association with disease susceptibility, along with a significant correlation between age and the chronicity of CCS. The serum cytokine levels were significantly different in CCS and controls.

Abstract
The present coronavirus disease 2019 (COVID-19) is spreading rapidly and existing data has suggested a number of susceptibility factors for developing a severe course of the disease. The current case-control experiment is aimed to study the associations of genetic polymorphisms in tumor necrosis factors (TNFs) with COVID-19 and its mortality rate. A total of 550 participants (275 subjects and 275 controls) were enrolled. The tetra-amplification refractory mutation system polymerase chain reaction technique was recruited to detect -308G>A TNFα and +252A>G TNFβ polymorphisms among the Iranian subjects. We demonstrated that carriers of the G allele of TNFβ-252A/G, rs909253 A>G were more frequent in COVID-19 subjects compared to the healthy group and this allele statistically increased the disease risk (odds ratio [OR] = 1.55, 95% confidence interval [CI] = 1.23-1.96, p < 0.0001). At the same time, the A allele of TNFα-311A/G, rs1800629 G>A moderately decreased the risk of COVID-19 (OR = 0.68, 95% CI = 0.53-0.86, p < 0.002). Also, we analyzed the various genotypes regarding the para-clinical and disorder severity; we found that in the AA genotype of TNFβ-252A/G (rs909253 A>G), the computed tomography scan pattern was different in comparison to cases carrying the AG genotype with p1 < 0.001. In addition, in the severe cases of COVID-19, leukocyte and neutrophil count and duration of intensive care unit hospitalization in the deceased patients were significantly increased (p < 0.001). Moreover, the TNFα-311A/G (rs1800629 G>A) variant is likely to change the pattern of splicing factor sites. Our findings provided deep insights into the relationship between TNFα/TNFβ polymorphisms and severe acute respiratory syndrome coronavirus 2. Replicated studies may give scientific evidence for exploring molecular mechanisms of COVID-19 in other ethnicities.

[PMID: 34735544 PMCID: PMC8568107 DOI: 10.1371/journal.pone.0259561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Accepted: 10/22/2021] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Osteoarthritis (OA) is an important health issue in elderly people. Many studies have suggested that genetic factors are important risk factors for OA, of which tumor necrosis factor-α (TNF-α) is one of the most examined genes. Moreover, several studies have investigated the relationship between TNF-α G-308A polymorphisms and OA risk, but consistent results have not been obtained. OBJECTIVE This study examines the association between TNF-α G-308A polymorphisms and knee OA. Moreover, meta-analysis and trial sequential analysis (TSA) was used to determine whether this is a susceptibility gene for knee OA. METHODS Between 2015 and 2019, 591 knee OA cases and 536 healthy controls were recruited. The Kellgren-Lawrence grading system was used to identify the knee OA cases. A meta-analysis was conducted including related studies published until 2020 from PubMed, Embase, and previous meta-analysis to improve the evidence level of the current study. The results were expressed as odds ratios (ORs) with corresponding 95% confidence intervals (CI) to evaluate the effect of this polymorphism on knee OA risk. The TSA was used to estimate the sample sizes required in this issue. RESULTS A nonsignificant association was found between the AA genotype and knee OA [adjusted OR, 0.84; 95% CI, 0.62-1.15) in the recessive model] in the present case-control study, and analysis of other genetic models showed a similar trend. After adding the critical case-control samples for Asians, the TNF-α G-308A, AA genotype exhibited 2.57 times more risk of developing arthritis when compared with the GG + GA genotype (95% CI, 1.56-4.23), and the cumulative samples for TSA (n = 2182) were sufficient to obtain a definite conclusion. CONCLUSIONS The results of this meta-analysis revealed that the TNF-α G-308A, AA genotype is a susceptible genotype for OA in the Asian population. This study integrated all current evidence to arrive at this conclusion, suggesting that future studies on Asians are not required.

Abstract
BACKGROUND Osteoarthritis (OA) is the most prevalent form of arthritis and the major cause of disability and overall diminution of quality of life in the elderly population. Currently there is no cure for OA, partly due to the large gaps in our understanding of its underlying molecular and cellular mechanisms. Macrophage migration inhibitory factor (MIF) is a procytokine that mediates pleiotropic inflammatory effects in inflammatory diseases such as rheumatoid arthritis (RA) and ankylosing spondylitis (AS). However, data on the role of MIF in OA is limited with conflicting results. We undertook this study to investigate the role of MIF in OA by examining MIF genotype, mRNA expression, and protein levels in the Newfoundland Osteoarthritis Study. METHODS One hundred nineteen end-stage knee/hip OA patients, 16 RA patients, and 113 healthy controls were included in the study. Two polymorphisms in the MIF gene, rs755622, and -794 CATT5-8, were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and PCR followed by automated capillary electrophoresis, respectively. MIF mRNA levels in articular cartilage and subchondral bone were measured by quantitative polymerase chain reaction. Plasma concentrations of MIF, tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-1 beta (IL-1β) were measured by enzyme-linked immunosorbent assay. RESULTS rs755622 and -794 CATT5-8 genotypes were not associated with MIF mRNA or protein levels or OA (all p ≥ 0.19). MIF mRNA level in cartilage was lower in OA patients than in controls (p = 0.028) and RA patients (p = 0.004), while the levels in bone were comparable between OA patients and controls (p = 0.165). MIF protein level in plasma was lower in OA patients than in controls (p = 3.01 × 10-10), while the levels of TNF-α, IL-6 and IL-1β in plasma were all significantly higher in OA patients than in controls (all p ≤ 0.0007). Multivariable logistic regression showed lower MIF and higher IL-1β protein levels in plasma were independently associated with OA (OR per SD increase = 0.10 and 8.08; 95% CI = 0.04-0.19 and 4.42-16.82, respectively), but TNF-α and IL-6 became non-significant. CONCLUSIONS Reduced MIF mRNA and protein expression in OA patients suggested MIF might have a protective role in OA and could serve as a biomarker to differentiate OA from other joint disorders.

Abstract
The present study aimed to identify key genes involved in osteoarthritis (OA). Based on a bioinformatics analysis of five gene expression profiling datasets (GSE55457, GSE55235, GSE82107, GSE12021 and GSE1919), differentially expressed genes (DEGs) in OA were identified. Subsequently, a protein-protein interaction (PPI) network was constructed and its topological structure was analyzed. In addition, key genes in OA were identified following a principal component analysis (PCA) based on the DEGs in the PPI network. Finally, the functions and pathways enriched by these key genes were also analyzed. The PPI network consisted of 241 nodes and 576 interactives, including a total of 171 upregulated DEGs [e.g., aspartylglucosaminidase (AGA), CD58 and CD86] and a total of 70 downregulated DEGs (e.g., acetyl-CoA carboxylase β and dihydropyrimidine dehydrogenase). The PPI network complied with an attribute of scale-free small-world network. After PCA, 47 key genes were identified, including β-1,4-galactosyltransferase-1 (B4GALT1), AGA, CD58, CD86, ezrin, and eukaryotic translation initiation factor 4 γ 1 (EIF4G1). Subsequently, the 47 key genes were identified to be enriched in 13 Gene Ontology (GO) terms and 2 Kyoto Encyclopedia of Genes and Genomes pathways, with the GO terms involving B4GALT1 including positive regulation of developmental processes, protein amino acid terminal glycosylation and protein amino acid terminal N-glycosylation. In addition, B4GALT1 and EIF4G1 were confirmed to be downregulated in OA samples compared with healthy controls, but only EIF4G1 was determined to be significantly downregulated in OA samples, as determined via a meta-analysis of the 5 abovementioned datasets. In conclusion, B4GALT1 and EIF4G1 were indicated to have significant roles in OA, and B4GALT1 may be involved in positive regulation of developmental processes, protein amino acid terminal glycosylation and protein amino acid terminal N-glycosylation. The present study may enhance the current understanding of the molecular mechanisms of OA and provide novel therapeutic targets.

Abstract
INTRODUCTION In our study we aimed to investigate the mechanism of Wnt inhibitory factor 1 (WIF1) on regulating chondrocyte proliferation and apoptosis via reactive oxygen species (ROS) and the Wnt/βcatenin signaling pathway in osteoarthritis (OA). MATERIAL AND METHODS Osteoarthritis chondrocytes were treated with interleukin 1β (IL-1β) to simulate an inflammatory condition. Quantitative real-time polymerase chain reaction (qRT-PCR) and western blot were applied for detecting WIF1 expression in OA chondrocytes. MTT assay and flow cytometry were carried out to analyze the cell proliferation and apoptosis. Content of ROS was detected using flow cytometry, and activity of the Wnt/βcatenin signaling pathway was detected using immunofluorescence, western blot and luciferase reporter assay. Western blot and enzyme-linked immunosorbent assay (ELISA) were performed to detect the expression of apoptosis-related proteins and secretion of matrix metalloproteinases (MMPs). RESULTS WIF1 expression in OA chondrocytes was significantly lower than in normal chondrocytes. After WIF1 cDNA transfection, the aberrantly high ROS level in OA chondrocytes was down-regulated, which led to the increase of proliferation and reduction of apoptosis. The Wnt/βcatenin signaling pathway was suppressed by WIF1 overexpression and the secretion of MMPs was therefore reduced. CONCLUSIONS Up-regulation of WIF1 would promote proliferation and suppress apoptosis of OA chondrocytes through eliminating ROS production and reduce secretion of MMPs via blocking the Wnt/βcatenin signaling pathway.

Abstract
Background Several studies suggest that there is a biologically plausible connection between rheumatoid arthritis (RA) and periodontal diseases (PD). Both disorders are characterized as multifactorial diseases potentially sharing common risk factors. Based on the inflammatory nature of RA and PD, the impact of genetic variations of genes of the immune system on both diseases was studied in this study. Materials and Methods We conducted a case-control study (n = 201) comparing 101 RA patients suffering from periodontal disease of different severities (no/mild PD vs. severe PD) with 100 systemically healthy controls without RA and severe PD. The genotype, allele, and haplotype distributions of 22 SNPs of 13 pro- and anti-inflammatory cytokines were assessed applying sequence-specific PCR. Results Evaluating the impact of cytokine SNPs in RA, we identified the G allele of rs1801275 in IL4Rα (p = 0.043) and the G allele of rs361525 in TNFα (p = 0.005) as disease-associated risk factors in bivariate analyses. In multivariate analyses, these significant associations could not be proven. The A allele of rs2430561 in IFNγ was indicative for severe periodontitis among the patients with rheumatoid arthritis (p = 0.039). Investigating the impact of rs2430561 in IFNγ on comorbidity using binary logistic regression analyses, the A allele was confirmed as an independent risk factor for severe periodontal disease and RA (p = 0.024). Conclusions These results emphasize the association of genetic variations in proinflammatory cytokines (TNFα and IFNγ) and cytokine receptor (IL4Rα) and RA and periodontal diseases. In multivariate analyses, the A allele of IFNγ was proven to be a significant marker of RA and PD comorbidities. The study broadens the knowledge about disease-specific differences in genetic composition and provides an improved understanding of a possible association of both diseases.

Abstract
SRY‑box 9 (SOX9) is the master regulator of the chondrocyte phenotype, which is essential for differentiating chondrogenic mesenchymal condensations into chondrocytes, and is involved in regulating every stage of chondrocyte differentiation. SOX9 deletion in chondrocytes at the late stages of cartilage development results in decreased chondrocyte proliferation; inhibited expression of cartilage matrix genes, including Indian hedgehog and the downstream parathyroid hormone‑related protein; and premature conversion of proliferating chondrocytes into hypertrophic chondrocytes, which mineralize their matrix prematurely. Therefore, SOX9 is considered vital for the majority of phases of chondrocyte lineage, from early condensations to the differentiation of proliferating chondrocytes, leading to chondrocyte hypertrophy. It has been reported that SOX9 expression is decreased in osteoarthritis (OA) cartilage. Regeneration or repair of cartilage degradation in OA remains a challenge. Previous studies have indicated that overexpression of SOX9 can promote cartilage repair and can be used as a potential therapeutic agent at the early stages of human OA. The present study identified Scm‑like with four malignant brain tumor domains 2 (SFMBT2) as a novel regulator of SOX9 expression in human chondrocytes. Our previous study revealed that SFMBT2 is negatively regulated in OA cartilage, and decreased levels of SFMBT2 contribute to the catabolic phenotype of chondrocytes. The present study detected increased expression levels of SFMBT2 in early cartilage development and during the early phases of chondrogenesis. Overexpression of SFMBT2 in C28/I2 cells upregulated SOX9 expression in a dose‑dependent manner. Furthermore, SFMBT2 positively regulated C28/I2 cell proliferation and restored the decreased levels of SOX9 in chondrocytes following tumor necrosis factor‑α treatment. Additional studies may reveal novel insights into the molecular mechanism involved and the potential role of SFMBT2 in cartilage repair and OA management.

Abstract
OBJECTIVE A comprehensive search on electronic databases was conducted to identify all eligible studies of TNF-α polymorphisms and knee osteoarthritis (OA). METHODS Eight studies on TNF-α -308 G > A and three on TNF-α -238G > A polymorphism were identified. RESULTS Overall, the pooled ORs indicated that neither TNF-α -238G > A nor -238G > A polymorphism was associated with knee OA risk. Similarly, in the stratified analysis by ethnicity, no significant association was found. CONCLUSION This meta-analysis results inconsistent with the previous meta-analyses showed that the TNF-α -308 G > A and -238G > A polymorphisms may not be associated with the susceptibility to knee OA.

Abstract
Osteoarthritis (OA) is a multifactorial disease characterized by low-grade inflammatory processes that are mediated initially by the cells and factors of the innate immune system. In addition to their key role in inflammation, cytokines contribute to the pathogenesis of OA through angiogenesis and chemotaxis. The purpose of the present case-control study was to investigate a possible association of four cytokine single nucleotide polymorphisms (SNPs), IL-4R -3223C>T (rs2057768), IL-8 -251T>A (rs4073), IL-10 -1082A>G (rs1800896) and TNF -A-308G>A (rs1800629) with OA susceptibility. Genomic DNA was isolated from blood samples collected from 305 Romanian subjects (90 patients with OA and 215 controls) and the genotyping of the SNPs was performed by TaqMan allelic discrimination polymerase chain reaction using predesigned assays. Our data indicated a significant association for IL-4R rs2057768 C>T SNP. The subjects that carried the CT genotype were at a higher risk for OA (OR 2.03, 95% CI: 1.21-3.42, P=0.007) compared with those that had the CC genotype. Furthermore, the carriers of the T allele were at a 1.9 fold higher risk for OA (OR 1.92; 95% CI, 1.17-3.17; P=0.009) in a dominant model. The association remained significant only for knee OA in the subgroups analysis. No correlations were observed between the other remaining SNPs and OA. The results suggested that the IL-4R rs2057768 SNP could contribute to OA susceptibility in the Romanian population, providing novel evidence for the involvement of IL-4/IL-4R pair in the pathogenesis of OA.

Abstract
Osteoarthritis (OA) is the most common degenerative disease affecting articular
cartilage. Some studies indicate that tumor necrosis factor alpha (TNF-α) gene
rs1800629 polymorphism was associated with OA risk among Caucasian populations.
To examine the role of this candidate gene in Asian populations, we conducted a
hospital-based case-control study involving 257 knee OA patients and 305
controls in a Chinese population. Genotyping was performed using a
custom-by-design 48-Plex single nucleotide polymorphism (SNP) Scan™
kit. Our study indicated that the AA genotype of TNF-α rs1800629 polymorphism
was associated with increased risk of OA. Subsequently, we conducted a
meta-analysis and found that rs1800629 polymorphism increased the risk of OA in
the recessive and homozygous models. Stratification analysis of ethnicity also
obtained a significant association among Asian populations. In conclusion, TNF-α
rs1800629 polymorphism confers susceptibility to OA, especially among Asians.
Larger studies with more diverse ethnic populations are needed to confirm these
results.

Abstract
OBJECTIVE To investigate the association of 14 cytokine gene polymorphisms with bronchopulmonary dysplasia (BPD) among Han Chinese newborns. The 14 polymorphisms investigated were IL18 rs1946519, rs1946518, rs187238, rs360718, and rs360717 polymorphisms, IL10 rs3024493 polymorphism, IL6 rs1800795, rs1800796, and rs1800797 polymorphisms, TNF rs361525 and rs1800629 polymorphisms, and TGFB1 rs1800469, rs1800468, and rs1800471 polymorphisms. WORKING HYPOTHESIS The polymorphisms could be associated with the risk of BPD among Han Chinese newborns. STUDY DESIGN, PATIENT-SUBJECT SELECTION, AND METHODOLOGY This is a retrospective study. Genotyping of these polymorphisms were performed on BPD cases (N = 1022) and non-BPD controls (N = 1039) who were ascertained using the established Jobe and Bancalari criteria. The odds ratios (ORs) of polymorphisms whose genotype distribution in the controls fulfilled the Hardy-Weinberg equilibrium (HWE) were calculated to evaluate the strengths of genetic association. RESULTS Genotype distributions of IL6 rs1800795 and rs1800797 polymorphisms deviated significantly from HWE and were omitted from the analysis. Among the 12 remaining polymorphisms, only TNF rs361525 polymorphism demonstrated a statistically significant association with BPD risk. The heterozygous GA genotype of TNF rs361525 polymorphism showed an OR of 1.932 (1.512-2.470), while the homozygous AA variant genotype showed an OR of 2.927 (1.216-7.048) (P = 0.000 and P = 0.017, respectively). Besides, the allelic OR was also analyzed, and it was found that the variant A allele of TNF rs361525 polymorphism showed an OR of 2.146 (1.718-2.680) (P = 0.000). CONCLUSION TNF rs361525 polymorphism could influence BPD risk among Han Chinese newborns.

Abstract
The aim of the present study was to investigate the relationship of four TNF-α SNP with inflammatory biomarkers and plasma fatty acids (FA), and the interaction among them in a population-based, cross-sectional study in São Paulo, Brazil. A total of 281 subjects, aged >19 and <60 years, participated in a cross-sectional, population-based study performed in Brazil. The following SNP spanning the TNF-α gene were genotyped: -238G/A (rs361525), -308G/A (rs1800629), -857C/T (rs1799724) and -1031T/C (rs1799964). In all, eleven plasma inflammatory biomarkers and plasma FA profile were determined. To analyse the interaction between TNF-α SNP and plasma FA, a cluster analysis was performed to stratify individuals based on eleven inflammatory biomarkers into two groups used as outcome: inflammatory (INF) and non-inflammatory clusters. The -238A allele carriers had higher TNF-α (P=0·033), IL-6 (P=0·013), IL-1β (P=0·037), IL-12 (0·048) and IL-10 (P=0·010) than the GG genotype. The -308A allele carriers also had lower levels of plasma palmitoleic acid (P=0·009), oleic acid (P=0·039), total MUFA (P=0·014), stearoyl-CoA desaturase (SCD) activity index-16 (P=0·007), SCD-18 (P=0·020) and higher levels of PUFA (P=0·046) and DHA (P=0·044). Significant interactions modifying the risk of belonging to the INF cluster were observed with inflammatory cluster as outcome between -857C/T and plasma α-linolenic acid (P=0·026), and also between -308G/A and plasma stearic acid (P=0·044) and total SFA (P=0·040). Our study contributes to knowledge on TNF-α SNP and their association with inflammatory biomarker levels, plasma FA and the interaction among them, of particular interest for the Brazilian population.

Abstract
BACKGROUND Associations of TNF-α-308 (rs1800629) and -238 (rs361525) with gastric cancer had the inconsistent indication among different populations. METHODS In this case-control family study, 47 families were determined with the probands diagnosed with gastric cancer (case family, n=296), accordingly 47 families without gastric cancer were matched with the case families by multivariate distribution of age, sex, social class, and pedigree size (control family, n=319). Polymerase chain reaction-restriction fragment length polymorphism (RFLP-PCR) was used to identify the TNF genotype. Chi-square test was used to compare the groups regarding genotype and the allele frequencies, HWE test for Hardy-Weinberg equilibrium. RESULTS The frequencies of TNF-α-308 GA and AA genotypes were significantly higher in case family than that in control family. The risk of gastric cancer was increased in GA and AA carriers in the first degree (OR=2.06, 95% CI=1.20-3.51 and OR=4.89, 95% CI=2.74-8.74), however the similar result was not found in the second degree. Helicobacter pylori infection status were significantly associated with risk of gastric cancer in first-degree relatives (OR=1.96, 95% CI=1.26-3.05) while no statistical significance was noted in the second-degree relatives. Haplotypes of TNF-α-308/-238 alleles, GA/GG, AA/GG and AA/GA indicated the susceptibilities to gastric cancer with OR and 95% confident intervals resulting 2.07 (1.34-3.21), 4.49 (2.74-7.33) and 4.98 (1.76-14.01) respectively. CONCLUSIONS TNF-α-G308A (rs1800629) polymorphisms are associated with gastric cancer in Chinese population. Haplotypes of TNF-α-308/-238 GA/GG, AA/GG and AA/GA increase the susceptibilities to gastric cancer. The first-degree relatives are more likely to develop into gastric cancer with TNF-α-G308 polymorphisms and H. pylori positive than the second-degree are.

Abstract
Background Immunosenescence is associated with several changes in adaptive and innate immune cells. Altered cytokine production is among the most prominent of these changes. The impact of age-related alterations on cytokine global profiles produced by distinct populations of leukocytes from healthy Brazilian individuals was studied. We analysed frequencies of cytokine-producing lymphocytes and innate immune cells from individuals at several ages spanning a lifetime period (0–85 years). Results Healthy adult individuals presented a balanced profile suggestive of a mature immune system with equal contributions of both innate and adaptive immunity and of both categories of cytokines (inflammatory and regulatory). In healthy newborns and elderly, innate immune cells, especially neutrophils and NK-cells, contributed the most to a balanced profile of cytokines. Conclusions Our results support the hypothesis that ageing is not associated with a progressive pro-inflammatory cytokine production by all leukocytes but rather with distinct fluctuations in the frequency of cytokine-producing cells throughout life.

Abstract
This study aims to examine whether the presence of polymorphisms in TNF-α (rs361525 and rs1799724) and MTHFR (rs1476413 and rs9651118) genes is associated with the pathogenesis of cerebral palsy (CP). A total of 105 CP patients and 114 age-, gender-, and ethnicity-matched healthy controls were genotyped for the selected polymorphisms, using TaqMan allelic discrimination assay. Odds ratios (OR) and 95 % confidence intervals (CI) were determined to measure the strength of associations of TNF-α and MTHFR polymorphisms with CP. The proportion of subjects with the gestational age more than 37 weeks or asphyxia was much larger in cases compared with controls (gestational age 63.8 vs. 34.2 %; asphyxia 25.7 vs. 7.9 %). The genotype frequencies of TNF-α rs1799724 were similar between groups (P > 0.05), yet the allele distributions were significantly different (P < 0.05). Both the allele and genotype distributions of MTHFR rs9651118 polymorphism varied significantly between the groups (P < 0.05). Subgroup analysis based on gestational age indicated a significant association between rs361525 and rs9651118 and CP with or without premature. TNF-α protein concentrations were significantly increased among patients with rs361525 GG genotype compared with controls. Also, a significant increase in the risk of CP was observed to be associated with the interactions of TNF-α rs1799724 and MTHFR rs9651118 (OR 2.75, 95 % CI 1.23-6.13). These data suggest that polymorphisms in TNF-α and MTHFR genes might be involved in the pathogenesis of CP in Chinese infants.

Abstract
Background Several case–control studies have been conducted to clarify the association between the tumor necrosis factor alpha (TNF-α) -G308A polymorphism and risk of osteoarthritis (OA); however, the results are inconsistent. This meta-analysis was performed to clarify this issue using all the available evidence. Methods Eligible articles were retrieved by searching PubMed, Web of science and Google scholar. The strength of the association between the TNF-α -G308A polymorphism and risk of OA was assessed by odds ratios (ORs) with the corresponding 95% confidence interval (CI) for each study. Results Seven studies were included in the meta-analysis, which included 983 OA cases and 1355 controls. The pooled analysis based on all included studies showed a significantly increased OA risk in the recessive genetic model analysis (OR = 11.08, 95% CI = 4.75-25.86, p < 0.001) and in the A allele vs. G allele analysis (OR = 2.30, 95% CI = 1.08-4.90). However, there was no statistical difference in the dominant genetic model analysis (OR = 2.45, 95% CI = 0.95-6.27, p = 0.06). Furthermore, we found that OA patients had a higher frequency of the AA genotype (OR = 10.49, 95% CI = 4.47-24.61) and GA genotype (OR = 1.78, 95% CI = 1.03-3.08) compared with the control population. Conclusion Our results suggested that the TNF-α -G308A polymorphism were associated with an increased risk of OA.

Abstract
Articular cartilage damage and subsequent degeneration are a frequent occurrence in synovial joints. Treatment of these lesions is a challenge because this tissue is incapable of quality repair and/or regeneration to its native state. Non-operative treatments endeavour to control symptoms and include anti-inflammatory medications, viscosupplementation, bracing, orthotics and activity modification. Classical surgical techniques for articular cartilage lesions are frequently insufficient in restoring normal anatomy and function and in many cases, it has not been possible to achieve the desired results. Consequently, researchers and clinicians are focusing on alternative methods for cartilage preservation and repair. Recently, cell-based therapy has become a key focus of tissue engineering research to achieve functional replacement of articular cartilage. The present manuscript is a brief review of stem cells and their potential in the treatment of early OA (i.e. articular cartilage pathology) and recent progress in the field.

Abstract
PURPOSE The purpose of this study was to investigate the possible association between single nucleotide polymorphisms (SNPs) rs1800629 (TNF-α -308) and rs361525 (TNF-α -238) of the tumour necrosis factor (TNF)-α gene and susceptibility to osteoarthritis (OA) in the Han Chinese population. METHODS The TNF-α -308 and -238 genotypes were determined by TaqMan assay in 200 OA cases and 305 controls. Odds ratios (ORs) for OA and 95% confidence intervals (CIs) from unconditional logistic regression models were used to evaluate relative risks. RESULTS The frequencies of the allele 'A' of rs1800629 were 16% and 8.85% in OA cases and in controls, respectively, and thus the -308A allele had a 1.9612-fold (95% CI = 1.3323-2.8869, P < 0.001) increased risk for OA as compared to the -308G allele. However, no significant differences were found in the genotype and allele frequencies for rs361525 between OA and HC groups. CONCLUSIONS In the Han Chinese population, the allele 'A' of TNF-α -308 may increase the risk for OA, whereas TNF-α -238 polymorphisms do not play a role in OA patients.

Abstract
Introduction The goal of this study is to investigate whether the -308G > A promoter polymorphism in the tumor necrosis factor alpha (TNFA) gene is associated with disease severity and radiologic joint damage in a large cohort of patients with rheumatoid arthritis (RA). Methods A long-term observational early RA inception cohort (n = 208) with detailed information about disease activity and radiologic damage after 3, 6 and 9 years of disease was genotyped for the TNFA -308G > A promoter polymorphism (rs1800629). A longitudinal regression analysis was performed to assess the effect of genotype on RA disease severity and joint damage. Subsequently, a meta-analysis, including all publically available data, was performed to further test the association between joint erosions and the TNFA polymorphism. To learn more about the mechanism behind the effect of the polymorphism, RNA isolated from peripheral blood from RA patients (n = 66) was used for TNFA gene expression analysis by quantitative PCR. Results Longitudinal regression analysis with correction for gender and disease activity showed a significant difference in total joint damage between GG and GA+AA genotype groups (P = 0.002), which was stable over time. The meta-analysis, which included 2,053 patients, confirmed an association of the genetic variant with the development of erosions (odds ratio 0.78, 95% CI 0.62, 0.98). No significant differences in TNFA gene expression were observed for the different genotypes, confirming earlier findings in healthy individuals. Conclusions Our data confirm that the TNFA -308G > A promoter polymorphism is associated with joint damage in patients with RA. This is not mediated by differences in TNFA gene expression between genotypes.
