  • Interleukin-12 (IL-12) as an antitumor and interleukin-6 (IL-6) as an inflammatory cytokine, are immunomodulatory products that play important roles in responses in cancers and inflammation. We tested the association between two polymorphisms of IL-12(1188A>C; rs3212227) and IL-6 (-174 C>G) and the risk of bladder cancer in 261 patients and 251 healthy individuals. We also investigated the possible association of these SNPs in patients with high-risk jobs and smoking habits with the incidence of bladder cancer. The genotype distributions of IL-6 (-174 C/G) genotype were similar between the cases and the control groups; however, among patients with smoking habits, the association between IL-6 gene polymorphism and incidence of bladder cancer was significant. After a control adjustment for age and sex, the following results were recorded: CC genotype (OR= 2.11, 95%CI=1.56-2.87, p=0.007), GC genotype (OR=2.18, 95%CI=1.16-4.12, p=0.014) and GC+CC (OR=2.6, 95%CI=1.43-4.47, p=0.011). A significant risk of bladder cancer was observed for the heterozygous genotype (AC) of IL-12 (OR=1.47, 95%CI=1.01-2.14, p=0.045) in all cases, and among smokers (AC) (OR=3.13, 95%CI=1.82-5.37, p=0.00014), combined AC+CC (OR=3.05, 95%CI=1.8-5.18, p=0.000015). Moreover among high risk job patients, there was more than a 3-fold increased risk of cancer in the carriers of IL-12 beta heterozygous (OR=3.7, 95%CI=2.04-6.57, p=0.000056) and combined AC+CC(OR=3.29, 95%CI=1.58-5.86, p=0.00002) genotypes as compared with the AA genotype with low-risk jobs. As a conclusion, this study suggests that IL-12(3'UTR A>C) and IL-6 (-174 C>G) genotypes are significantly associated with an increased risk of bladder cancer in the Iranian population with smoking habits and/or performing high-risk jobs.

  • Resveratrol은 천연 stilbene으로 안전성 있는 항염증 활성을 가진 화합물로 알려져 있다. 최근의 연구들에서 resveratrol이 천식, 만성 대장염, 류마티스성 관절염과 같이 염증에 의해 발생하는 다양한 질병을 억제한다고 보고되었다. 이러한 연구들은 resveratrol이 $CD4^+$ helper T cells (Th cells)에 의한 면역반응을 조절할 것이라고 제시하였다. 그러나 resveratrol이 직접적으로 Th cells의 활성화와 분화를 조절하는지 완전히 밝혀지지 않았다. C57BL/6에서 Th cells을 분리하여 다양한 농도의 resveratrol을 세포에 처리하였다. 본 연구에서는 resveratrol이 직접적으로 Th cells의 활성화와 증식을 억제하는 것을 확인하였다. Th cells에 resveratrol을 처리하였을 때 IFN-${\gamma}$, IL-4, IL-17 사이토카인 생성이 농도에 따라 유의하게 감소하였고 또한 Th cells이 이러한 사이토카인들을 분비하는 Th1과 Th2과 Th17으로 분화되는 것이 억제되었다. 그리고 고농도의 resveratrol이 Th cells의 세포사멸을 유도하는 것으로 확인되었다. 본 연구에서는 resveratrol이 Th cells의 활성화와 분화를 직접적으로 억제하는 것을 확인하였으며, 이는 resveratrol이 $CD4^+$ Thcells에 의해 발생되는 자가면역질환의 효과적인 치료법이 될 수 있을 것이라고 제시한다.

  • PURPOSE. This study was to investigate the effects of recombinant human platelet-derived growth factor (rhPDGF-BB) and heparin to titanium surfaces for enhancement of osteoblastic functions and inhibition of inflammation activity. MATERIALS AND METHODS. The anodized titanium discs, not coated with any material, were used as a control group. In heparinized-Ti group, dopamine was anchored to the surface of Ti substrates, and coated with heparin. In PDGF-Ti group, rhPDGF-BB was immobilized onto heparinized Ti surface. The surface morphologies were investigated by the scanning electron microscope in each group. The release kinetics of rhPDGF-BB were analyzed, and cytotoxicity tests for each group were conducted. The biocompatibilities were characterized by measuring cell proliferation, alkaline phosphatase activity, and calcium deposition using MG-63 cells. Statistical comparisons were carried out by one-way ANOVA tests. Differences were considered statistically significant at $^*$P<.05 and $^{**}$P<.001. RESULTS. The combination of rhPDGF-BB and heparin stimulated alkaline phosphatase activity and OCN mRNA expression in osteoblastic cells ($^*$P<.05 and $^{**}$P<.001). MG-63 cells grown on PDGF-Ti had significantly higher amounts of calcium deposition than those grown on anodized Ti ($^{**}$ P<.001). Heparinized Ti was more anti-inflammatory compared to anodized Ti, when exposed to lipopolysaccharide using the transcript levels of TNF-${\alpha}$ and IL-6 of proinflammatory cytokine ($^*$P<.05 and $^{**}$P<.001). CONCLUSION. The result of this study demonstrated that the incorporation of rhPDGF-BB and heparin onto Ti surface enhanced osteoblastic functions and inhibited inflammation.

  • Background: C-reactive protein (CRP), considered as a prototypical inflammatory cytokine, has been proposed to be involved in tumor progression through inflammation. Recent studies have indicated CRP as a progostic predictor for urological cancers, but the results remain controversial. Materials and Methods: A systematic search of Medline, Scopus and the Cochrane Library was performed to identify eligible studies published between Jan 1, 2001 and Sep 1, 2013. Outcomes of interest were collected from studies comparing overall survival (OS), cancer-specific survival (CSS) and relapse-free survival (RFS) in patients with elevated CRP levels and those having lower levels. Studies were pooled, and combined hazard ratio (HR) of CRP with its 95% confidence interval (CI) for survival were used for the effect size estimate. Results: A total of 43 studies (7,490 patients) were included in this meta-analysis (25 for RCC, 10 for UC, and 8 for PC). Our pooled results showed that elevated serum CRP level was associated with poor OS (HR: 1.26, 95%CI: 1.22-1.30) and RFS (HR: 1.38 95%CI: 1.29-1.47), respectively. For CSS the pooled HR (HR: 1.33, 95%CI: 1.28-1.39) for higher CRP expression could strongly predict poorer survival in urological cancers. Simultaneously, elevated serum CRP was also significantly associated with poor prognosis in the subgroup analysis. Conclusions: Our pooled results demonstrate that a high serum level of CRP as an inflammation biomarker denotes a poor prognosis of patients with urological cancers. Further large prospective studies should be performed to confirm whether CRP, as a biomarker of inflammation, has a prognostic role in urological cancer progression.

  • Background: HCV is a major global health problem. IL-27 is a member of the IL-6/IL-12 cytokine family with a broad range of anti-inflammatory properties. Recent studies highlighted the effect of a SNP in the IL-27 promoter region on modulating the progression of infectious diseases and individual responses to therapy. Aim of the work: The present study investigated the potential role of (-964 A/G) SNP in the promoter region of IL-27p28 gene (alleles rs153109) on the outcome of HCV infection among genotype 4a infected patients. Materials and Methods: HCV genotyping confirmed that all of the HCV-infected patients had genotype 4a infection. Genomic DNA was extracted from 111 patients with chronic HCV infection, 42 spontaneous resolvers (SR) and 16 healthy controls. IL- 27p28.rs153109 genotyping was assessed using PCR-RFLP then confirmed by DNA sequencing. Results: The frequency of IL-27-p28.rs153109AA, AG, and GG genotypes among chronically infected subjects were 74.8 %, 25.2%, and 0% while among the SR, they were 57.1%, 35.7%, and 7.14%, respectively. Our data show the unique presence of G/G genotype in the SR group (3 patients; 7.14%). Moreover, the "G" allele frequencies among chronic and resolved subjects were 12.6% and 25.0%, respectively (p=0.0136). Importantly, subjects with the GG genotype were more likely to clear their HCV infection than those with the AA genotype (p=0.0118). Conclusions: HCV genotype 4a subjects with the IL-27-p28.rs153109 A/G and G/G genotype were more likely to clear their HCV infection. Therefore, we propose IL- 27p28.rs153109SNPas a genetic biomarker for predicting HCV infection outcome.

  • Objectives: The purpose of this study is to investigate the effects of Yijungtang(YJT) on atopic dermatitis in an in-vitro and in-vivo experiment using a RBL-2H3 mast cells and a NC/Nga atopic dermatitis mouse. Methods: In-vitro experiment, IL-4, IL-13 mRNA expression were evaluated by a real-time PCR, IL-4, IL-13 production by ELISA and transcription factor as GATA-1, GATA-2, NF-AT1, NF-AT2, AP-1 and NF-kB by western blotting. In-vivo experiment, clinical skin score we evaluated by, hematology and Serum total IgE and IgG1 of NC/Nga atopic dermatitis mouse, cytokine level, total number of cell, Immunohistochemical staining and Histological features of auxiliary lymph node(ALN), draining lymph node(DLN), peripheral blood mononuclear cells(PBMCs) and dorsal skin tissue in NC/Nga mouse. Results: YJT decreased IL-4, IL-13 mRNA expression, IL-4, IL-13 production and prominently decreased the expression of mast cell specific transcription factors including GATA-2, NF-AT2, c-Fos and NF-kB. YJT oral administration reduced the levels of skin severity scores. It also decreased the level of inflammatory cytokines such as IL-5, IL-13, histamine and IgE in the serum. It elevated IFN-gamma level in the spleenocyte culture supernatant but decreased. $CD3e^+$, $CD19^+$, $CD4^+$, $CD8^+$, $CD3e^+CD69^+$, $CD11b^+Gr-1^+$, $CCR3^+$ in the PBMCs, $CD4^+$, $CD8^+$, $CD3e^+CD69^+$, $B220^+CD23^+$ in the ALN, $CD4^+$, $CD3e^+CD69^+$ in the ALN and $CD4^+$, $CD11b^+Gr-1^+$ in the dorsal skin. Histological examination showed that infiltration levels of immune cells in the skin of AD-induced NC/Nga mice were much improved by YJT oral administration. Conclusions: The anti-allergic activities of YJT may be mediated by down-regulation of Th2 cytokines, such as IL-4 and IL-13, through the regulation GATA-2, NF-AT2 and NF-kB transcription factors in mast cells. YJT would be regulate molecular mediators and immune cells which are functionally associated with atopic dermatitis induced in NC/Nga mice, and may play an important role in recovering AD symptoms.

  • Objectives The purpose of this study is to investigate the effect of SPDJTK(SoPungDoJeokTangKami) and concurrent administration of AJ(Atopy cream, Jawoongo)+SPDJTK on atopic dermatitis-like skin lesions by using in NC/Nga atopic dermatitis mouse induced by BMAC-induced mice. Methods Clinical skin score, hematology and Serum total IgE and IgG1 of NC/Nga atopic dermatitis mice were evaluated. Moreover, the cytokine level, total cell number, Immunohistochemical staining and Histological features of axillary lymph node(ALN), draining lymph node(DLN), peripheral blood mononuclear cells(PBMCs) and dorsal skin tissue were used in NC/Nga mice. Results Orally administrated SPDJTK with concurrent administration of SPDJTK and AJ decreased the clinical skin score, total cell number of WBC, eosinophils in blood, serum total IgE & IgG1, IL-5, IL-13, IFN-$\gamma$. Also, total cell number of ALN and dorsal skin tissue, absolute cell number of CD4+, CD8+, CD3+CD69+, CD3+CCR3+, CCR3+, CD4+CXCR5+ in ALN, absolute cell number of CD3+CCR3+, CCR3+ in DLN, granulocytes in PBMCs, activation cell number of CD3+CD69+, CCR3+, total cell number of CD3+ T cell in dorsal skin tissue were significantly decreased. Furthermore, thickness of epidermis, infiltrated inflammatory immune cell and mast cell in dermis, amount of Eotaxin2 mRNA, CCR3 mRNA in dorsal skin tissue, gene expression of IL-5, IL-13 mRNA in ALN, CD4+ Th cell in dorsal skin tissue and CCR3+ eosinophils in ALN were all significantly decreased. However, total number of DLN, absolute number of CD3e+ T cell and CD19+ B cell, absolute number of CD4+, number of Th cell in DLN and gene expression of foxp3 mRNA were significantly increased significantly. Conclusions Concurrent administration of SPDJTK and AJ on atopic dermatitis in NC/Nga atopic dermatitis mouse was very effective treatment for atopic dermatitis.

  • Leptin is an adipocyte-secreted hormone and its plasma levels correlate with total body fat mass, however, it also plays a regulatory role in immunity, inflammation, and hematopoiesis. Chemokine is known as a chemoattractant cytokine in inflammatory reaction, but its role in leptin reaction has not been well studied. In this study, the direct effect of leptin on the expression of chemokine mRNAs and lipopolysaccharide (LPS)-induced chemokine KC mRNA in mouse peritoneal macrophages was investigated. Leptin did not induce the expression of lymphotactin, RANTES, eotaxin, MIP-1$\beta$, MIP-1$\alpha$, MIP-2, MCP-1, IP-10, TCA-3, and KC mRNA in mouse peritoneal macrophages, and had no direct effect on the expression of these LPS-induced chemokine mRNAs except KC mRNA. The synergistic effect of leptin on the expression of LPS-induced KC mRNA occurred late in the time course of response to LPS. The increased expressions of Ob-Rb mRNA and leptin receptor protein were detected during the LPS treatment. Leptin produced a substantial increase in the stability of the LPS-induced KC mRNA, and the synergistic effect of leptin on LPS-induced KC mRNA expression was further augmented by cycloheximide (CHX). Pyrrolidine dithiocarbamate (PDTC) did not block the synergistic effect of leptin on LPS-induced KC mRNA expression in mouse peritoneal macrophages. These data suggest that although leptin has no direct effect on the expression of lymphotactin, RANTES, eotaxin, MIP-1$\beta$, MIP-1$\alpha$, MIP-2, MCP-1, IP-10, TCA-3, and KC mRNA in mouse peritoneal macrophages, the synergistic effect of leptin on the expression of LPS-induced KC mRNA has the possibility that LPS might induce the expression of the Ob-Rb receptor or an unknown gene(s) that sensitizes macrophages to the synergistic function of leptin. Therefore, further studies are necessary to examine leptin as a regulatory factor of chemokine production.
