Budhiparama NC, Lumban-Gaol I, Sudoyo H, Magetsari R, Wibawa T. The role of genetic polymorphisms of interleukin-1 (IL-1R1 and IL-1RN) in primary knee osteoarthritis in Indonesia. Sci Rep 2023; 13:7967. [PMID: 37198429 DOI: 10.1038/s41598-023-34824-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Accepted: 05/09/2023] [Indexed: 05/19/2023] Open
Abstract
This study aimed to evaluate the association of SNPs of the IL-1 family with the clinical severity of knee OA. This case‒control study was performed among 100 healthy knees and 130 osteoarthritis (OA) knees of people aged ≥ 50 years with a BMI ≥ 25 kg/m2. The possible correlations among clinical findings, radiographic evaluations, serum levels of IL-1R1 and IL-1Ra, and genotype analyses were evaluated. Three SNPs of IL-1R1, rs871659, rs3771202, and rs3917238, were associated with primary knee OA. Females with IL-1R1 SNP rs871659 allele A had a higher prevalence of primary knee OA. No correlation was found between SNPs of IL-1R1 and IL-1RN and clinical or radiologic severity or serum concentrations of IL-1R1 and IL-1Ra (p > 0.05). BMI and IL-1R1 rs3917238 genotype C/C were correlated with moderate-severe VAS scores. A correlation was also found between the EQ-5D-3L self-care dimension and obesity and between the EQ-5D-3L pain and usual activity dimensions and age ≥ 60 and obesity (p < 0.05). Radiologic severity was only associated with age ≥ 60 years (p < 0.05). We found the IL-1R1 SNPs rs871659, rs3771202, and rs3917238 to be predisposing factors for primary knee osteoarthritis. The clinical findings, radiographic severity, and serum concentrations of IL-1R1 and IL-1Ra were not correlated with these gene polymorphisms.

Abstract
Thyroid cancer is the most common endocrine malignancy, with an increasing trend in the past decades. It has a variety of different histological subtypes, the most frequent one being differentiated thyroid cancer, which refers to papillary carcinoma, the most common histological type, followed by follicular carcinoma. Associations between genetic polymorphisms and thyroid cancer have been investigated over the years and are an intriguing topic for the scientific world. To date, the results of associations of single nucleotide polymorphisms, the most common genetic variations in the genome, with thyroid cancer have been inconsistent, but many promising results could potentially influence future research toward developing new targeted therapies and new prognostic biomarkers, thus consolidating a more personalized management for these patients. This review focuses on emphasizing the existing literature data regarding genetic polymorphisms investigated for their potential association with differentiated thyroid cancer and highlights the opportunity of using genetic variations as biomarkers of diagnosis and prognosis for thyroid cancer patients.

Int J Gen Med 2021; 14:2147-2159. [PMID: 34093035 PMCID: PMC8169084 DOI: 10.2147/ijgm.s291395] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 04/16/2021] [Indexed: 12/02/2022] Open
Abstract
Background Rheumatoid arthritis (RA), an autoimmune systemic inflammatory disease, largely resulted from genetic factor. Our purpose was to explore the association for IL1R1 and IL1R2 genetic variants with RA susceptibility in the Chinese Han population. Patients and Methods A total of 508 RA patients and 494 controls were involved in this case–control study; single-nucleotide polymorphisms (SNPs) genotyping was identified by the Agena MassARRAY platform. The relationship between polymorphisms and RA susceptibility was calculated using the Pearson’s Chi-square test with odds ratios and 95% confidence intervals (CIs) in multiple genetic models. The Pearson’s Chi-square test and Student’s t-test were used for sample basic characteristic analysis. And linkage disequilibrium (LD) analysis and haplotype analysis were performed by logistic regression analysis. Results The result from this study showed that rs2072472 (IL1R2) was an increased risk factor of RA (adjusted OR = 1.41, p = 0.011). Stratified analysis indicated SNPs rs10490571, rs956730, rs3917318 of IL1R1, and SNPs rs4851527, rs719250, rs3218896, rs3218977, rs2072472 of IL1R2 had impacts on RA risk after stratification based on gender and average age (54 years). Finally, haplotype analysis revealed that Ars3218977Ars2072472 haplotype in IL1R2 was related to a decreased RA risk (adjusted OR = 0.79; 95% CI = 0.65–0.94; p = 0.010). Yet, rs3917225(IL1R1) and rs11674595(IL1R2) were not significant in RA association analysis. Conclusion We determined SNPs (rs3917318, rs956730, rs1049057) of IL1R1 and SNPs (rs3218977, rs719250, rs4851527, rs3218896, rs2072472) of IL1R2 were correlated with the RA susceptibility in the Chinese Han population.

Compressive mechanical stress enhances susceptibility to interleukin-1 by increasing interleukin-1 receptor expression in 3D-cultured ATDC5 cells. BMC Musculoskelet Disord 2021; 22:238. [PMID: 33648469 PMCID: PMC7923672 DOI: 10.1186/s12891-021-04095-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Accepted: 02/17/2021] [Indexed: 12/31/2022] Open
Abstract
Background Mechanical overload applied on the articular cartilage may play an important role in the pathogenesis of osteoarthritis. However, the mechanism of chondrocyte mechanotransduction is not fully understood. The purpose of this study was to assess the effects of compressive mechanical stress on interleukin-1 receptor (IL-1R) and matrix-degrading enzyme expression by three-dimensional (3D) cultured ATDC5 cells. In addition, the implications of transient receptor potential vanilloid 4 (TRPV4) channel regulation in promoting effects of compressive mechanical loading were elucidated. Methods ATDC5 cells were cultured in alginate beads with the growth medium containing insulin-transferrin-selenium and BMP-2 for 6 days. The cultured cell pellet was seeded in collagen scaffolds to produce 3D-cultured constructs. Cyclic compressive loading was applied on the 3D-cultured constructs at 0.5 Hz for 3 h. The mRNA expressions of a disintegrin and metalloproteinases with thrombospondin motifs 4 (ADAMTS4) and IL-1R were determined with or without compressive loading, and effects of TRPV4 agonist/antagonist on mRNA expressions were examined. Immunoreactivities of reactive oxygen species (ROS), TRPV4 and IL-1R were assessed in 3D-cultured ATDC5 cells. Results In 3D-cultured ATDC5 cells, ROS was induced by cyclic compressive loading stress. The mRNA expression levels of ADAMTS4 and IL-1R were increased by cyclic compressive loading, which was mostly prevented by pyrollidine dithiocarbamate. Small amounts of IL-1β upregulated ADAMTS4 and IL-1R mRNA expressions only when combined with compressive loading. TRPV4 agonist suppressed ADAMTS4 and IL-1R mRNA levels induced by the compressive loading, whereas TRPV4 antagonist enhanced these levels. Immunoreactivities to TRPV4 and IL-1R significantly increased in constructs with cyclic compressive loading. Conclusion Cyclic compressive loading induced mRNA expressions of ADAMTS4 and IL-1R through reactive oxygen species. TRPV4 regulated these mRNA expressions, but excessive compressive loading may impair TRPV4 regulation. These findings suggested that TRPV4 regulates the expression level of IL-1R and subsequent IL-1 signaling induced by cyclic compressive loading and participates in cartilage homeostasis.

Abstract
The Longlin goat is one of the most valuable livestock species in Guangxi Autonomous Region of China, but its genomic diversity and selective signals are not clearly elucidated. Here we compared 20 genomes of Longlin goat to 66 genomes of other seven goat breeds worldwide to analyze patterns of Longlin goat genetic variation. We found the lowest linkage disequilibrium at the large distances between SNPs associated with the highest effective population size in the recent generations ago in Longlin goat. The eight goat breeds could be divided into Euro-African and East Asian goat population. Interestingly, like East Asian taurine, the same two migration phases might have occurred in the history of East Asian goat. More importantly, we identified selective signals implicated in immune resistance to disease, especially for skin disease, in Longlin goat. Our findings will not only help understand the evolutionary history and breed characteristic but can provide valuable resources for conservation of germplasm resources and implementation of crossbreeding programs.

Abstract
AIM The incidence of head and neck cancer (HNC) is increasing but its pathogenic factors are complex. Changes in both internal (genetic) and external (environmental) causes HNC to some extent. The purpose of our study was to investigate the influence of IL1R1 polymorphisms on HNC risk in Chinese Han population. METHODS Genotypes of 535 HNC patients and 538 healthy controls were analyzed by Agena MassARRAY. Odds ratio (ORs) and 95% confidence interval (CIs) were calculated by logistic regression analysis to evaluate the relationship between single nucleotide polymorphisms (SNPs) and HNC susceptibility. RESULTS It was found that the rs956730 of IL1R1 reduced the risk of HNC in multiple models (allele: OR = 0.76, 95% CI: 0.62-0.93, p = 0.008; codominant: OR = 0.43, 95% CI: 0.25-0.75, p = 0.003; recessive: OR = 0.45, 95% CI: 0.26-0.77, p = 0.004; additive: OR = 0.77, 95% CI: 0.63-0.94, p = 0.01). IL1R1 rs956730 had a protective effect on HNC at age ≤ 46. However, the rs3917225 increased a 1.31-fold HNC risk in the codominant model (OR = 1.31, 95% CI: 1.00-1.70, p = 0.03). CONCLUSION Our study showed that the rs956730 of IL1R1 gene in Chinese Han population was associated with a reduced risk of HNC, while the rs3917225 of IL1R1 might increase the risk of HNC.

Abstract
Background Age-related hearing impairment (ARHI) is a major disability among the elder population. Chronic inflammation is an important factor in the development of ARHI. Interleukin-1 (IL-1) plays a key role in inflammation and may be associated with ARHI. The aim of this study is to analyze the associations of single nucleotide polymorphisms (SNPs) of IL-1 receptor genes with ARHI in an elderly population in Taiwan. Method Participants ≥65 years of age were recruited for audiometric tests and genetic analyses. The bilateral pure-tone average (PTA) of high-tone hearing levels was calculated for ARHI evaluation. The associations of SNPs of the IL-1 receptor type 1 gene (IL1R1) (rs3917225 and rs2234650) and type 2 gene (IL1R2) (rs4141134 and rs2071008) with ARHI were analyzed in 182 ARHI-susceptible (case) and 176 ARHI-resistant (control) participants. Results The G allele of IL1R1 rs3917225 showed a decreased risk of ARHI after adjustments for sex, age, and noise exposure. The GG genotype of IL1R1 rs3917225 in all hereditary models and the TT genotype of IL1R2 rs2071008 in the recessive model also showed decreased risks of ARHI after adjustments. Conclusion These findings suggest that IL1R1 and IL1R2 polymorphisms may contribute to the decreased risk of ARHI in the elderly population.

Abstract
Background The aim of this study was to assess the association of single-nucleotide polymorphisms (SNPs) in IL1R1 with the risk of lumbar disc herniation (LDH) in the Han population in northwest China. Material/Methods To estimate the association of IL1R1 polymorphisms with LDH risk, Agena MassARRAY was used to determine the genotypes of 498 LDH patients and 463 controls. The association between IL1R1 variants and LDH risk was examined by logistic regression analysis with adjustments for age and gender. Stratification analysis was observed between gender and age with polymorphisms of IL1R1. Haplotype construction and analysis in IL1R1 were also applied to detect the potential association. Results The mutant homozygous genotype in codominant model (AA versus GG, OR=2.37, 95% CI: 1.08–5.21, P=0.001) and in recessive model (AA versus GG/GA, OR=2.82, 95% CI: 1.30–6.12, P=0.005) of rs956730 were associated with an increased LDH risk in males, while rs956730 heterozygous genotype under codominant model (AG versus GG, OR=0.65, 95% CI: 0.46–0.92, P=0.001) was a protective genotype in males. In addition, the recessive model (CT/CC versus TT, OR=3.43, 95% CI: 1.11–10.57, P=0.020) of rs10490571 was associated with an increased LDH risk among people older than 50 years of age. Conclusions This study demonstrated that genetic variants in the IL1R1 genes were associated with LDH risk in the Han population of northwestern China.

Abstract
BACKGROUND Thyroid carcinoma accounts for a large part of endocrine neoplasia and the relationship between inflammation and thyroid cancer has been validated previously. Two known receptors of interleukin (IL)-1, IL-1 receptor 1 (IL1R1) and IL-1 receptor 2 (IL1R2), are implicated in numerous inflammatory responses. The present study aimed to assess the genetic polymorphisms of IL1R1 and IL1R2 with respect to thyroid cancer in the Chinese Han population. METHODS Eleven single nucleotide polymorphisms of IL1R1 and IL1R2 were identified among 241 thyroid cancer patients and 463 controls using the Agena MassARRY method (http://www.internationalgenome.org). Genetic models and haplotype analysis were carried out to evaluate the significant links between the variants and the risk of thyroid cancer. RESULTS Logistic regression analyses revealed significant associations of rs3917225, rs2072472 and rs11674595 with susceptibility to thyroid cancer. Haplotype analysis presented two blocks of IL1R2, whereas no statistical significance existed. CONCLUSIONS These findings suggested that rs3917225, rs2072472 and rs11674595 are risk factors associated with the development of thyroid carcinoma in Chinese Han people.

MyD88 and IL-1R signaling drive antibacterial immunity and osteoclast-driven bone loss during Staphylococcus aureus osteomyelitis. PLoS Pathog 2019; 15:e1007744. [PMID: 30978245 PMCID: PMC6481883 DOI: 10.1371/journal.ppat.1007744] [Citation(s) in RCA: 50] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2018] [Revised: 04/24/2019] [Accepted: 04/01/2019] [Indexed: 01/18/2023] Open
Abstract
Staphylococcus aureus is able to infect virtually all organ systems and is a frequently isolated etiologic agent of osteomyelitis, a common and debilitating invasive infection of bone. Treatment of osteomyelitis requires invasive surgical procedures and prolonged antibiotic therapy, yet is frequently unsuccessful due to extensive pathogen-induced bone damage that can limit antibiotic penetration and immune cell influx to the infectious focus. We previously established that S. aureus triggers profound alterations in bone remodeling in a murine model of osteomyelitis, in part through the production of osteolytic toxins. However, staphylococcal strains lacking osteolytic toxins still incite significant bone destruction, suggesting that host immune responses are also major drivers of pathologic bone remodeling during osteomyelitis. The objective of this study was to identify host immune pathways that contribute to antibacterial immunity during S. aureus osteomyelitis, and to define how these immune responses alter bone homeostasis and contribute to bone destruction. We specifically focused on the interleukin-1 receptor (IL-1R) and downstream adapter protein MyD88 given the prominent role of this signaling pathway in both antibacterial immunity and osteo-immunologic crosstalk. We discovered that while IL-1R signaling is necessary for local control of bacterial replication during osteomyelitis, it also contributes to bone loss during infection. Mechanistically, we demonstrate that S. aureus enhances osteoclastogenesis of myeloid precursors in vitro, and increases the abundance of osteoclasts residing on bone surfaces in vivo. This enhanced osteoclast abundance translates to trabecular bone loss, and is dependent on intact IL-1R signaling. Collectively, these data define IL-1R signaling as a critical component of the host response to S. aureus osteomyelitis, but also demonstrate that IL-1R-dependent immune responses trigger collateral bone damage through activation of osteoclast-mediated bone resorption.

Mol Genet Genomic Med 2019; 7:e00557. [PMID: 30623603 PMCID: PMC6418375 DOI: 10.1002/mgg3.557] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Revised: 10/29/2018] [Accepted: 12/13/2018] [Indexed: 12/17/2022] Open
Abstract
Aim Osteonecrosis of the femoral head (ONFH) refers to bony changes caused by osteocyte death under the effects of complicated factors, which is caused by genetic factors and certain risk factors. Our study aimed to explore whether IL1R1/IL1R2 polymorphisms influenced ONFH risk in the Chinese Han population. Methods We selected 286 patients and 441 controls, with 11 single‐nucleotide polymorphisms in IL1R1 and IL1R2 gene were successfully genotyped, and evaluated the associations using the chi‐squared test, Fisher's exact test, T test, and genetic model analyses. Odds ratios and 95% confidence intervals (CIs) were calculated using unconditional logistic regression. Results In the allele model, rs11674595 in IL1R2 was associated with increasing the risk of ONFH, the rs10490571 and rs3917225 in IL1R1 gene were associated with an increased risk of ONFH, respectively. In the genetic model, the rs11674595 in IL1R2 gene was associated with an increased risk of ONFH in the codominant model, dominant model, and log‐additive model, respectively. The rs10490571 and rs3917225 in IL1R1 gene conferred an increased risk of ONFH in the codominant model, dominant model, and log‐additive model, respectively. We found none of the haplotypes in the IL1R2 gene was significantly associated with theONFH risk. Conclusion Our findings have demonstrated that the rs11674595 (IL1R2), rs10490571, and rs3917225 (IL1R1) were significantly associated with increasing the ONFH risk in the Chinese Han population.

Effect of miR-495 on lower extremity deep vein thrombosis through the TLR4 signaling pathway by regulation of IL1R1. Biosci Rep 2018; 38:BSR20180598. [PMID: 30287499 PMCID: PMC6435557 DOI: 10.1042/bsr20180598] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Revised: 08/30/2018] [Accepted: 09/17/2018] [Indexed: 12/11/2022] Open
Abstract
Lower extremity deep vein thrombosis (LEDVT), a common peripheral vascular disease caused by a blood clot in a deep vein is usually accompanied by swelling of the lower limbs. MicroRNAs (miRs) have been reported to play roles in LEDVT. We aimed to investigate the effect of miR-495 on LEDVT via toll-like receptor 4 (TLR4) signaling pathway through interleukin 1 receptor type 1 (IL1R1). LEDVT mouse model was established, and the femoral vein (FV) tissues were collected to detect expressions of miR-495, IL1R1, and TLR4 signaling-related genes. The expressions of both CD31 and CD34 (markers for endothelial progenitor cells) in the FV endothelial cells as well as the proportion of CD31+/CD34+ cells in peripheral blood were measured in order to evaluate thrombosis. The effect of miR-495 on cell viability, cell cycle, and apoptosis was analyzed. IL1R1 was confirmed as the target gene of miR-495. Besides, inhibiting the miR-495 expression could increase IL1R1 expression along with activating the TLR4 signaling pathway. The total number of the leukocytes along with the ratio of weight to length of thrombus in the FV tissue showed an increase. The overexpression of miR-495 could promote FV endothelial cell viability. By injecting agomiR-495 and antagomiR-495 in vivo, the number of leukocytes in the FV tissues and the ratio of weight to length of thrombus were significantly decreased in the mice injected with the overexpressed miR-495, and the IL1R1/TLR4 signaling pathway was inhibited. Collectively, overexpressed miR-495 directly promotes proliferation while simultaneously inhibiting apoptosis of FV endothelial cells, alleviating FV thrombosis by inhibiting IL1R1 via suppression of TLR4 signaling pathway.

Analyses of changes in myocardial long non-coding RNA and mRNA profiles after severe hemorrhagic shock and resuscitation via RNA sequencing in a rat model. BMC Mol Biol 2018; 19:11. [PMID: 30384838 PMCID: PMC6211518 DOI: 10.1186/s12867-018-0113-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Accepted: 10/19/2018] [Indexed: 12/18/2022] Open
Abstract
Background Ischemia–reperfusion injury has been proven to induce organ dysfunction and death, although the mechanism is not fully understood. Long non-coding RNAs (lncRNAs) have drawn wide attention with their important roles in the gene expression of some biological processes and diseases, including myocardial ischemia–reperfusion (I/R) injury. In this paper, a total of 26 Sprague–Dawley (SD) rats were randomized into two groups: sham and ischemia–reperfusion (I/R) injury. Hemorrhagic shock was induced by removing 45% of the estimated total blood volume followed by reinfusion of shed blood. High-throughput RNA sequencing was used to analyze differentially expressed (DE) lncRNAs and messenger RNAs (mRNAs) in the heart tissue 4 h after reperfusion. Myocardial function was also evaluated. Results After resuscitation, the decline of myocardial function of shocked animals, expressed by cardiac output, ejection fraction, and myocardial performance index (MPI), was significant (p < 0.05). DE lncRNAs and mRNAs were identified by absolute value of fold change ≥ 2 and the false discovery rate ≤ 0.001. In rats from the I/R injury group, 851 lncRNAs and 1015 mRNAs were significantly up-regulated while 1533 lncRNAs and 1702 m RNAs were significantly down-regulated when compared to the sham group. Among the DE lncRNAs, we found 12 location-associated with some known apoptosis-related protein-coding genes which were up-regulated or down-regulated accordingly, including STAT3 and Il1r1. Real time PCR assays confirmed that the expression levels of five location-associated lncRNAs (NONRATT006032.2, NONRATT006033.2, NONRATT006034.2, NONRATT006035.2 and NONRATT029969.2) and their location-associated mRNAs (STAT3 and Il1r1) in the rats from the I/R injury group were all significantly up-regulated versus the sham group. Conclusions The DE lncRNAs (NONRATT006032.2, NONRATT006033.2, NONRATT006034.2 and NONRATT006035.2) could be compatible with their role in myocardial protection by stimulating their co-located gene (STAT3) after hemorrhagic shock and resuscitation. The final prognosis of I/R injury might be regulated by different genes, which is regarded as a complex network.

Abstract
BACKGROUND Interleukin (IL)-1 has been reported to be involved in the development of tuberculosis (TB). IL1R1 and IL1R2 encode a cytokine receptor that belongs to the IL-1 receptor family. However, few studies have reported on the polymorphisms of IL1R1 and IL1R2 in TB patients. METHODS We investigated nine single-nucleotide polymorphisms (SNPs) in IL1R1 and IL1R2 in 300 TB patients and 300 controls, aiming to evaluate their association with TB risk. Odds ratios and 95% confidence intervals were calculated using unconditional logistic regression after adjusting for age and gender. RESULTS On comparing the allele frequencies of candidate SNPs, we found that the minor allele 'A' of rs4851527 in IL1R2 was associated with a decreased risk of TB, whereas the minor alleles of rs10490571, rs956730 and rs3917225 in IL1R1 were associated with an increased risk of TB (p < 0.05). In the genetic model analysis, we found that the allele 'A' of rs4851527 was correlated with a decreased risk of TB in a log-additive model, whereas the minor alleles of rs719250, rs3218977, rs10490571, rs956730 and rs3917225 were correlated with an increased risk of TB in dominant and log-additive models (p < 0.05). Additionally, we found three haplotypes that were associated with an increased risk of TB: TGCT and TGTT haplotypes constructed by rs11674595, rs4851527, rs719250 and rs3218896, as well as GA haplotype constructed by rs3218977 and rs2072472 (p < 0.05). CONCLUSIONS Our data shed new light on the association between genetic polymorphisms of IL1R1 and IL1R2 and TB susceptibility in the Chinese Han population.

A case-control study and meta-analysis reveal the association between COX-2 G-765C polymorphism and primary end-stage hip and knee osteoarthritis. J Clin Lab Anal 2018; 32:e22412. [PMID: 29453810 PMCID: PMC6816993 DOI: 10.1002/jcla.22412] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2017] [Accepted: 01/24/2018] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Osteoarthritis (OA) is a popular arthrosis featured as pain, limited joint activity, and deformity. Cyclooxygenase-2 (COX-2) has been reported to be up-regulated in arthritic tissues and is integral to the progression of osteoarthritis (OA). Previous studies showed the COX-2 promoter G-765C polymorphism could influence COX-2 expression. However, the relationship between the variant and OA risk is contrasting. METHODS We conducted a case-control study with 196 primary end-stage hip and knee OA cases and 196 controls in a Chinese Han population. Subsequently, we integrated this case-control study in a meta-analysis to acquire greater statistical power. The results from our case-control study using MassARRAY genotyping technology and binary logistic regression statistical methods. RESULTS The variant carriers in the Chinese Han population had a lower primary end-stage hip and knee OA susceptibility (C vs G: OR = 0.350, 95%CI: 0.154-0.797, P = .012; GC vs GG: adjusted OR = 0.282, 95%CI: 0.118-0.676, P = .005). Stratification studies indicated that a higher GC frequency in women decreased not only knee OA susceptibility but also unilateral knee OA risk. The meta-analysis showed that the variant exhibited a significantly decreased OA risk through comparisons involving allelic, homozygous, heterozygous, and dominant models. CONCLUSION Our findings suggest that the COX-2 G-765C polymorphism exerts a protective effect against primary end-stage knee osteoarthritis in a female Chinese Han population.
