Abstract A study from Thailand showed no significant association between the adiponectin (ADIPOQ) gene rs1501299 polymorphism and knee osteoarthritis (OA) risk. To investigate this association in a Chinese population, we conducted this case–control study involving 372 knee OA patients and 453 controls. Genotyping via standard PCR and restriction fragment length polymorphism (PCR-RFLP) showed that TT genotype (TT vs. GG: adjusted odds ratio (OR) (95% confidence interval (CI)) = 1.70 (1.01–2.86)) or T allele (T vs. G: adjusted OR (95% CI) = 1.26 (1.02–1.56)) of ADIPOQ gene rs1501299 polymorphism significantly increased the risk of knee OA. Significant associations were also observed in subgroups ≥55 years (TT vs. GG: adjusted OR (95% CI) = 2.21 (1.00–4.86)) and body mass index (BMI) < 25 kg/m2 (TT+GT vs. GG: adjusted OR (95% CI) = 1.53 (1.03–2.29)), but not in the subgroup analysis of sex. In conclusion, the ADIPOQ gene rs1501299 polymorphism intensifies the risk of knee OA in this Chinese Han population. Nevertheless, further studies with larger sample sizes in other populations are warranted to verify this finding.

AbstractBackground/aims: Studies have demonstrated that osteopontin (OPN) was associated with the severity and development of knee osteoarthritis (OA). Methods: The purpose of this case–control study was to investigate the association between OPN gene rs11730582 polymorphism and knee OA risk in a Chinese population. Genotyping was analyzed using standard PCR and restriction fragment length polymorphism (PCR-RFLP). Results: The present study found that C allele or CC genotype of OPN gene rs11730582 polymorphism was related to decreased risk for knee OA. Furthermore, positive associations were obtained amongst the females, and body mass index (BMI) < 25 kg/m2 groups. Conclusions: To sum up, the present study reveals that OPN gene rs11730582 polymorphism decreases the risk of knee OA in Chinese Han population.

Abstract Background: There is an association between Interleukin-6 (IL-6) polymorphism and knee osteoarthritis (OA) risk. The case-control study aims at exploring how IL-6 rs12700386 polymorphism affects the knee OA risk in Chinese Han individuals.Methods: We extracted the DNA from 763 participants, thereinto, 352 were OA patients and 411 were healthy controls. The polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assisted in genotyping the IL-6 gene polymorphism. The relative expression exhibited by IL-6 in blood samples of knee OA patients was determined via a quantitative reverse transcription PCR (qRT-PCR). Results: We found that IL-6 rs12700386 enhanced the knee OA susceptibility. Based on a subgroup analysis, the loci magnified the knee OA risk in smokers, drinkers, and subjects ≥ 55 years old or with BMI ≥ 25 kg/m2. The combination of smoking and drinking and rs12700386 genotype led to an increase in the knee OA risk, indicating an underlying interaction between gene and environment. Additionally, the rs12700386 was found to be related to increased IL-6 gene levels. Conclusion: These data indicate that rs12700386 polymorphism of IL-6 gene led to an increase in the knee OA risk specific to Chinese Han individuals.

Matrix metalloproteinase 1 (MMP-1) degrades cartilage, which may result in osteoarthritis (OA) development. Several studies have explored the association between MMP-1 gene rs1799750 polymorphism and OA in different populations. However, the results are inconsistent. The aim of this case–control study was to investigate the association between MMP-1 gene rs1799750 polymorphism and knee OA in a Chinese population. The present study included 308 cases and 404 controls. Genotyping was performed using standard polymerase chain reaction and restriction fragment length polymorphism. The present study found that 2G2G genotype (2G2G vs 1G1G: OR & 95% CI, 2.28 (1.47–3.53), P<0.001; 2G2G + 1G2G vs 1G1G: OR & 95% CI, 1.61 (1.15–2.24), P=0.005; 2G2G vs 1G2G + 1G1G: OR & 95% CI, 1.84 (1.26–2.68), P=0.002) or 2G allele carriers (2G vs 1G: OR & 95% CI, 1.48 (1.20–1.83), P<0.001) of MMP-1 gene rs1799750 polymorphism increased the risk of OA. In conclusion, this case–control study confirms that MMP-1 gene rs1799750 polymorphism increases the risk of knee OA in Chinese Han population.

Abstract Epidermal Growth factor (EGF) could induce colorectal cancer (CRC) cell to develop epithelial mesenchymal-transition and enhance their ability to invade and migrate. Several studies have thrown light on the association between EGF gene polymorphism and risk of CRC, but with conflicting results. Therefore, we determined EGF A61G polymorphism by using PCR-restriction fragment length polymorphism method in 341 CRC cases and 472 controls in a Chinese population. Our results showed that EGF A61G polymorphism increased the risk of CRC in a Chinese population (GG vs AA: adjusted OR: 1.92; 95% CI: 1.27–2.91; P=0.002; GG+AG vs AA: adjusted OR: 1.43; 95% CI: 1.05–1.94; P=0.022; GG vs AG+AA: adjusted OR: 1.65; 95% CI: 1.15–2.39, P=0.007; G vs A: OR: 1.39; 95% CI: 1.14–1.69, P=0.001). Stratified analyses revealed that the significant association was more evident in the females, smokers, drinkers, and old subjects (age ≥60 years). Furthermore, the GG and/or AG genotype carriers were more likely to have larger tumor size and lymph node metastasis. In conclusion, EGF A61G polymorphism is a genetic contributor to CRC in a Chinese Han population.

We also found that IL-6 levels were significantly higher in the CC genotype compared to the GG genotype carriers in OA patients.Conclusion: These data suggest that the rs12700386 polymorphism in the IL-6 gene leads to an increase in the risk of knee OA in Chinese Han individuals.

Abstract Several studies have explored the association between matrix Gla protein (MGP) gene polymorphism and knee osteoarthritis (OA) risk; however, they obtained conflicting findings. The present study aims to explore the association of MGP gene polymorphism and OA risk in a Chinese Han population. A total of 256 patients with radiographic knee OA and 327 control subjects were recruited in this case–control study. The genotypes of MGP gene rs1800802 polymorphism was determined by standard PCR and restriction fragment length polymorphism (PCR-RLFP). In this case–control study, we observed that MGP gene rs1800802 polymorphism increased the risk of knee OA. Subgroup analyses also found that rs1800802 polymorphism was related to the elevated risk for knee OA among the female, smoker, drinker, and body mass index (BMI) ≥25 kg/m2 groups. In conclusion, this study shows that MGP gene rs1800802 polymorphism is associated with increased risk for knee OA in Chinese Han population and the rs1800802 polymorphism may be a diagnostic marker of radiographic knee OA.
