Aims: This study was conducted to evaluate the levels of TNF-${\alpha}$, IL-6, IL-8 and VEGF in serum of patients with non- small cell lung cancer, for assessing their possible diagnostic and prognostic roles. Methods: We enrolled 48 patients newly diagnosed with non-small cell lung cancer and 40 healthy controls. TNF- ${\alpha}$, IL-6 and IL-8 levels were measured in the serum of all the subjects with specific radioimmunoassay kits, while EGF was analyzed by sandwich enzyme immunoassay techniques. Results: A statistically significant difference was observed between lung cancer patients and the control group regarding the values of TNF-${\alpha}$, IL-6, IL-8 and VEGF in serum. Moreover, TNF-${\alpha}$, IL-8 and VEGF levels were higher in patients with advanced stages compared to early stages. In addition, higher serum levels of TNF-${\alpha}$, IL-6, IL-8 and VEGF were found in smokers than in non-smokers, both in patients and controls. Conclusion: Serum levels of TNF-${\alpha}$, IL-6, IL-8 and VEGF were all elevated in lung cancer patients, suggesting that inflammatory cytokines could be jointly used as a screening tool. Though TNF-${\alpha}$, IL-8 and VEGF levels were related to advanced disease, long-term survival studies of NSCLC patients should be performed to confirm whether they can act as biomarkers of advanced disease. In addition, smoking would be an important contributor to the processes of inflammation and lung cancer.

Bee venom (BV) therapy has been used as a traditional medicine to treat a variety of conditions, such as arthritis, back pain, cancerous tumors, and skin diseases. However, regulatory effects of BV on tumor necrosis factor (TNF)-${\alpha}$-induced HaCaT cell migration or anti-inflammatory have not been explored. In the present study, we investigated the effects of BV on HaCaT cell migration and anti-inflammation. HaCaT cell migration was evaluated by wound-healing assay. The pro-inflammatory cytokines such as TNF-${\alpha}$, interleukin (IL)-$1{\beta}$, and IL-8 were examined by ELISA or Western blotting. BV treatment led to an increase in migration of HaCaT cells for 24 and 48 h. Especially, 10 ng/ml of BV were significantly increased HaCaT cell migration. Also, BV suppressed the secretion of TNF-${\alpha}$, IL-$1{\beta}$, and IL-8 in culture medium with HaCaT cells. In addition, Western blot results demonstrate that BV suppressed the expression of TNF-${\alpha}$ and IL-$1{\beta}$, in HaCaT cells. Especially, 1 or 10 ng/ml of BV markedly decreased the expression of pro-inflammatory cytokines. These results demonstrate the potential of BV for the prevention of skin inflammation induced by TNF-${\alpha}$.

Male genital tract inflammatory conditions may be associated with unexplained infertility. The presence of cytokine such as tumor necrosis factor-alpha (TNF-${\alpha}$) was reported in the semen of infertile men. However, the effect of these cytokines on human sperm function is still unclear. The purpose of this study was to investigate the in-vitro effects of TNF-alpha on human sperm motility with computer assisted sperm analysis. Washed sperm from 16 normal men were incubated without and with TNF-${\alpha}$ (0.1, 10, 1000 ng/ml). The changes of parameters of sperm motility were recorded at different time intervals (0, 5, 24 hour). There was no significant change of parameters of sperm motility in the incubation with TNF-${\alpha}$. It is suggested that TNF-${\alpha}$ alone does not interfere with the sperm motility and more studies are needed.

본 연구는 염증상태에서의 CLA의 효과와 작용기전을 알아보기 위해 LPS-자극 RAW 264.7 macrophages에 있어 ROS 생성과 TNF-${\alpha}$ 생산, NF-${\kappa}B$ 및 $PPAR{\gamma}$ 활성을 검토하였다. t10c12-CLA는 LPS로 자극하지 않은 비염증시의 RAW 세포에서는 ROS 생성을 증가시켜 TNF-${\alpha}$ 생산을 유도하였으며, 이 효과는 $PPAR{\gamma}$ 활성화에 의존해서 NF-${\kappa}B$ 활성 증가에 의해 매개되었다. 반면, LPS로 자극한 염증조건의 RAW 세포에서는 t10c12-CLA가 $PPAR{\gamma}$ 활성화에 의존하지 않는 경로로 ROS 생성 및 과도한 TNF-${\alpha}$ 생산을 억제하였다. 본 결과로부터 CLA는 ROS 생성을 통해 TNF-${\alpha}$ 생산 및 NF-${\kappa}B$ 활성을 염증 유무에 따라 조절하는 것으로 사료되었다.

Purpose: The purpose of this study was to verify that the expressions of angiogenin, transforming growth factor-beta(TGF-${\beta}$), vascular endothelial growth factor(VEGF), human apurinic/apyrimidinic endonuclease(APEX) and tumor necrosis factor-alpha(TNF-${\alpha}$) were associated with the tumorigenesis of the oral squamous cell carcinoma(OSCC). Materials and Methods: Fifty-one samples of OSCC and fifteen normal oral mucosae were obtained to analyze the expression levels of above five factors. mRNA expressions were quantified by the quantitative competitive PCR(QC-PCR) method. After 2% agarose gel electrophoresis stained with ethidium bromide, the concentration of mRNA was calculated by a digital image analysis system. The expression levels of angiogenin, TGF-${\beta}$, VEGF, APEX and TNF-${\alpha}$ were compared by unpaired Student's t-tests between cancer and normal tissues. We analyzed statistically to find the cut-off values that would be useful as diagnostic markers, and the linear regression analysis between every two factors of these five factors by SAS system. Results: All of these five factors (angiogenin: P<0.0037, TGF-${\beta}$: P<0.0001, VEGF: P<0.0102, APEX: P<0.0023, TNF-${\alpha}$: P<0.0074) were significantly correlated with OSCC. In the analysis to find the cut-off values for the diagnosis, we could not find any value that had a reasonable sensitivity and specificity. In the linear regression analysis, there were correlations between angiogenin and TNF-${\alpha}$, TGF-${\beta}$ and VEGF, TGF-${\beta}$ and APEX, TGF-${\beta}$ and TNF-${\alpha}$, VEGF and APEX, VEGF and TNF-${\alpha}$, APEX and TNF-${\alpha}$. Conclusion: Our results suggest that not only angiogenin, TGF-${\beta}$, VEGF, APEX and TNF-${\alpha}$ are significantly associated with the tumorigenesis, but also the close relationship between these factors might enhance the tumorigenesis of OSCC. We can not find clinical availability for diagnosis.

연구배경 : 만성폐쇄성폐질환 환자의 체중감소는 질환의 자연경과로 조직의 산소소모량을 최소로 유지하기 위한 일종의 신체적응과정으로 이해하였다. 그러나 만성폐쇄성폐질환 환자의 체중감소가 에너지대사량 증가와 관계 있고, 체중감소가 심한 환자들은 폐기능의 감소정도와 상관없이 이환율과 사망률이 증가한다는 연구결과가 보고된 후, 영양학적인 부분에 대하여 관심을 가지게 되었다. 저자들은 만성폐쇄성폐질환자 중 만성기관지염 환자와 폐기종 환자의 폐기능과 체성분을 측정하여 혈중 leptin농도 및 $TNF-{\alpha}$ system 과의 관계를 비교하여, 체중감소와의 관계를 알아보았다. 방 법 : 미국흉부학회의 진단기준에 따라 1초간 노력성 호기량이 예측치의 80% 미만이고, 노력성 폐활량에 대한 1초간 노력성 호기량의 비 ($FEV_1$/FVC)가 70% 미만인 41명의 환자를 대상으로 하였다. Kco가 60미만인 경우를 폐기종으로, 80이상인 경우를 만성기관지염으로 분류하였으며, 체성분 분석, 및 혈중 leptin농도, 그리고 $TNF-{\alpha}$ system의 활성도를 측정하였다. 결 과 : 만성기관지염 환자 및 폐기종 환자의 혈중 leptin농도는 각각 $1378.1{\pm}428.3pg/ml/kg$, $947.0{\pm}441.0pg/ml/kg$로 만성기관지염 환자가 유의하게 높았으며, 이들 값을 체지방량으로 교정하였을 때도 $180.9{\pm}57.7pg/ml/kg$, $108.5{\pm}39.4pg/ml/kg$로 만성기관지염 환자가 유의하게 높았다 (p<0.05). 혈중 $TNF-{\alpha}$ system 은 $TNF-{\alpha}$, sTNF-R75는 양 군에서 차이가 없었으나, sTNF-R55는 폐기종 환자군에서 $920.4{\pm}116.4pg/ml$로 만성기관지염 환자보다 유의하게 높았다 (p<0.05). 혈중 leptin농도는 체지방량 및 체질량지수와 상관관계가 있었으며, sTNF-R55는 체지방량이나 체질량지수와 관계가 없었다. 또한 sTNF-R55의 활성도는 혈중 leptin농도와도 무관하였다. 결 론 : 만성기관지염에 비하여 체중감소가 심한 폐기종의 체중감소에는 혈중 leptin보다는 $TNF-{\alpha}$ system이 관계할 것으로 생각되며, $TNF-{\alpha}$ system은 혈중 leptin와는 무관하게 작용할 것으로 생각한다. 그러나 앞으로 이에 대하여 더 많은 환자를 대상으로 한 연구가 있어야 하겠으며, 만성폐쇄성폐질환자의 체중변화에 영향을 줄 수 있는 영양섭취, 운동량, 안정시 에너지소모량 및 다른 사이토카인 등과의 관계에 대한 연구도 이루어져야 할 것이다.

Ellagitannins have been reported to enhance the immune system. In this study, the effects of pedunculagin on langerhans cells were examined. Pedunculagin, an ellagitannin from Alnus hirsuta var. microphylla. Betulaceae, is a novel immunomodulator. Langerhans cell are known as the potent antigen presenting cell and elicit the Contact Hypersensitivity (CHS) response by presenting Ag to trafficking Ag-specific T cells within the skin. For determining the effects af pedunculagin on murine langerhans cell, the expression of TNF-$\alpha$ mRNA was examined by RT-PCR. As a result, the expression of TNF-$\alpha$ mRNA was upregulated by pedunculagin. These results suggest that pedunculagin enhances TNF-$\alpha$ and could be used as an immunomodulator in skin immune system.

Apoptosis of vascular smooth muscle cell is observed in the vascular diseases such as atherosclerosis and restenosis. The death of vascular smooth muscle cells can be induced by cytokines and activation of Fas-pathways. It is widely accepted that apoptosis occurs without inflammation. There are, however, reports that apoptosis is not silent. Vascular smooth muscle cells dying by Fas-pathway secreted inflammatory cytokines including monocyte chemoattractant protein-1. This study have investigated whether apoptosis is associated with potent inflammatory cytokine tumor tumor necrosis factor (TNF)-${\alpha}$. The cells which undergo apoptosis by expressing FADD in the absence of tetracycline expressed and secreted TNF-${\alpha}$. When the level of TNF-${\alpha}$ transcript was investigated, dying smooth muscle cells exhibited transcriptional activation of TNF-${\alpha}$. The data indicate that dying vascular smooth muscle cells contribute to inflammation by expressing inflammatory cytokines. The present study suggests that apoptosis could not be silent in certain pathological situations.

Sparganosis is a tissue invading helminthiasis infecting intermediate hosts, including humans. Strong immune responses are expected to occur in early phases of infection. Thus, we investigated cytokine expressions in splenic dendritic cells and in sera after experimental infection of mice. In splenic dendritic cells, TNF-${\alpha}$ and IL-$1{\beta}$ expression peaked at week 1 and week 3 post -infection (PI), respectively, and also early phase (week 2 PI) depressed cytokine expression was noticed. Serum IL-$1{\beta}$ concentration increased significantly at week 2 PI and peaked at week 6 PI, and that of TNF-${\alpha}$ peaked at week 6 PI. These results showed that pro-inflammatory cytokines, TNF-${\alpha}$ and IL-$1{\beta}$, are chronologically regulated in mouse sparganosis.

Objectives : Tumor necrosis factor-${\alpha}$(TNF ${\alpha}$) is a proinflammatory cytokine involved in the pathogenesis of rheumatoid arthritis. This study was designed to investigate the relation between TNF-${\alpha}$ gene polymorphism and rheumatoid arthritis in Korean population. Methods : This study was carried out on 103 rheumatoid arthritis patients who fulfilled the American College of Rheumatology 1987 revised criteria for rheumatoid arthritis and 208 healthy control subjects. Blood samples from all subjects were obtained for DNA extraction. The extracted DNA was amplified by polymerse chain reaction(PCR). PCR products were visualized by 2% agarose gel electrophoresis. We investigated the genotyping of TNF-${\alpha}$ by using Pyrosequencing. Results: The genotypes of TNF-${\alpha}$ gene were GG, AG and AA. While the distribution of TNF-${\alpha}$ polymorphism in control subjects was 92.31%, 7.21%, 0.48% respectively, in rheumatoid arthritis patients was 93.20%, 6.80%, 0.00%(GG, AG, AA). There was no statistical significant allelic frequency difference between control and rheumatoid arthritis groups. Conclusions : We concluded that there was no significant association between TNF-${\alpha}$ gene polymorphism and rheumatoid arthritis. However, the findings of this study need to be confirmed in more patients and further studies.
