이 연구의 목적은 신체활동이 마이오카인 발현에 미치는 영향을 보고자 문헌고찰을 하였다. 신체적인 활동은 제2형 당뇨, 심혈관질환, 대장암, 치매 및 우울증과 같은 질환을 예방하는 역할을 하고 있다. 그리고 마이오카인(myokine)은 운동 훈련에 의해 분비되는 호르몬으로 뇌성장이나 알츠하이머 같은 질환 예방에 도움을 준다. 운동수행과정에서 수축하는 근육으로부터 분비되는 항염증 마이오카인의 생성과 대사 조절에 필요한 분비 활성화가 건강증진에 중요한 요인으로 보고 있다. 인체 골격근에서 분비되는 마이오카인 가운데 IL-4, IL-6, IL-7, IL-8, IL-15 등은 근육비대(hypertrophy)와 세포(myogenesis) 및 혈관생성(angiogenesis) 등의 조절에 관여한다. IL-6는 AMPK 활성화로 인한 대사중 지방 산화를 촉진시키는 작용을 하고, IL-1Ra, IL-10 과 sTNF-R 는 염증성 싸이토카인 $TNF-{\alpha}$의 분비를 억제한다. IL-15는 저항 운동시 근수축을 통한 발현량이 증가하어 근육 성장의 중요 합성요인으로 작용한다. 한편 IL-7 및 IL-8도 신호 전달 수용체 C-X-C를 통해 혈관신생을 촉진시킨다.

Objectives : This study aimed to investigate the protective effects of mixed extracts from Scutellaria baicalensis Georgi, Alisma orientale Juzepzuk, and Atractylodes japonica Koidzumi on interleukin (IL)-6-induced damage to tight junction (TJ) integrity in a Caco-2 cell model. Methods : We assessed the TJ integrity of Caco-2 monolayers by measuring the flux of FITC-labeled dextran and transepithelial electrical resistance (TEER). Additionally, we evaluated the expression of TJ proteins, such as ZO-1 and Occludin. Results : Treatment with IL-6 (50 ng/ml) increased TJ permeability and decreased TEER values of Caco-2 monolayers. Pretreatment with HTB (50-200 ㎍/ml) for 1 h significantly alleviated IL-6-induced TJ disruption, as evidenced by reduced TJ permeability and increased TEER values. Furthermore, HTB reversed the IL-6-induced inhibition of TJ protein expression, including ZO-1 and Occludin. Conclusions : These findings indicate that HTB protects barrier function by reversing the IL-6-induced decrease in TJ integrity and the suppression of TJ protein expression.

Pheochromocytomas and paragangliomas (PPGLs) may secrete hormones or bioactive neuropeptides such as interleukin-6 (IL-6), which can mask the clinical manifestations of catecholamine hypersecretion. We report the case of a patient with delayed diagnosis of paraganglioma due to the development of IL-6-mediated systemic inflammatory response syndrome (SIRS). A 58-year-old woman presented with dyspnea and flank pain accompanied by SIRS and acute cardiac, kidney, and liver injuries. A left paravertebral mass was incidentally observed on abdominal computed tomography (CT). Biochemical tests revealed increased 24-hour urinary metanephrine (2.12 mg/day), plasma norepinephrine (1,588 pg/mL), plasma normetanephrine (2.27 nmol/L), and IL-6 (16.5 pg/mL) levels. ¹⁸F-fluorodeoxyglucose (FDG) positron emission tomography/CT showed increased uptake of FDG in the left paravertebral mass without metastases. The patient was finally diagnosed with functional paraganglioma crisis. The precipitating factor was unclear, but phendimetrazine tartrate, a norepinephrine-dopamine release drug that the patient regularly took, might have stimulated the paraganglioma. The patient's body temperature and blood pressure were well controlled after alpha-blocker administration, and the retroperitoneal mass was surgically resected successfully. After surgery, the patient's inflammatory, cardiac, renal, and hepatic biomarkers and catecholamine levels improved. In conclusion, our report emphasizes the importance of IL-6-producing PPGLs in the differential diagnosis of SIRS.

Interleukin (IL) 17 is produced by T-helper (Th) 17 with a vigorous effect on cells of the immune system playing important roles in pathogenesis of immune-mediated diseases, including autoimmune disorders and cancers. Therefore, the aim of current study was to determine the serum levels of IL-6, IL-17, and transforming growth factor beta (TGF-${\beta}$) in Iranian bladder cancer patients, and to correlate them with disease status. Blood samples were collected from 40 bladder cancer patients and 38 healthy individuals with no history of malignancies or autoimmune disorders. The serum levels of IL-6, IL-17, and TGF-${\beta}$ were measured by the enzyme-linked immunosorbent assay (ELISA). The results showed that the levels of IL-17 (p<0.0001) and TGF-${\beta}$ (p<0.0001) were significantly lower in the patients compared to the controls. No significant differences in the level of serum IL-6 (p=0.16) was observed between the patients and controls. In addition, demographic characteristics between control and patients groups were not significantly different. As most of the cases studied in this investigation were in stage I and II, it is concluded that reduced Th17-related cytokines can be used as indicators for following the course and clinical stages of bladder carcinoma progress and immune response to cancer.

Sinensetin, a pentamethoxyflavone, is known to exert various pharmacological activities including anti-angiogenesis, anti-diabetic and anti-inflammatory activities. However, its effects on the human mast cell - 1 (HMC-1) mediated inflammatory mechanism remain unknown. To explore the mediator and cellular inflammatory response of sinensetin, we examined its influence on phorbol 12-myristate 13-acetate (PMA) plus A23187 induced inflammatory mediator production in a human mast cell line. In this study, interleukin (IL)-6 production was measured using the enzyme-linked immunosorbent assay and reverse transcription polymerase chain reaction. Sinensetin inhibited PMA plus A23187 induced IL-6 production in a dose-dependent manner as well as IL-4, IL-5 and IL-8 mRNA expression. Furthermore, sinensetin inhibited signal transducer and activator of transcription 3 (STAT3) phosphorylation, suggesting that sinensetin inhibits the production of inflammatory mediators by blocking STAT3 phosphorylation. Moreover, sinensetin was found to inhibit nuclear factor kappa B activation. These findings suggest that sinensetin may be involved in the regulation of mast cell-mediated inflammatory responses.

Yangdan-tang (YD) is recorded as a treatment to treat exterior-related fever illness in the Korean medicine. In this study, we examined the anti-inflammatory effects of YD, using YD water extract and lipopolysaccharide (LPS)-induced RAW 264.7 cells. First of all, we measured the amount of nitric oxide (NO) and prostaglandin E2 (PGE2), the products of inflammatory metabolism. Also, we measured enzymes such as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), as well as cytokines such as tumor necrosis factor alpha (TNF-α), interleukin 6 (IL-6), interleukin 1 alpha (IL-1α), and interleukin 1 beta (IL-1β). YD suppressed the production of NO and PGE2 in a dose dependent manner and reduced the amount of protein and the mRNA expression of iNOS and COX-2. Also, YD reduced the mRNA expression of TNF-α, IL-6, IL-1α and IL-1β. In conclusion, YD decreased production of LPS-induced inflammatory factor, which could be a clinical basic subject for inflammatory diseases.

Objectives : This study was performed to investigate the effects of Foeniculum Vulgare(FV) extract on the anti-inflammatory of lipopolysaccharide(LPS) exposed rats. Methods : We divided LPS exposed Sprague-Dawley rats into 4 groups. They were control group, feed with 100 mg/kg, 200 mg/kg, 300 mg/kg FV groups. They were administered for 6 weeks. We measured the concentration of plasma interleukin-1${\beta}$(IL-1${\beta}$), plasma interleukin-6(IL-6), plasma tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), plasma interleukin-10(IL-10), the concentration of liver IL-1${\beta}$, IL-6, TNF-${\alpha}$ and IL-10. Results : 1. Plasma IL-1${\beta}$, plasma IL-6 and plasma TNF-${\alpha}$ concentration increased rapidly at 2hours after LPS injection and maintained high levels at 5hours after LPS injection. The concentration of these cytokines in the FV extract groups showed lower values than control group(P<0.05). 2. The concentration of Plasma IL-10 in FV extract groups showed higher values than control group at all times(P<0.05). 3. The concentration of liver IL-1${\beta}$ and IL-6 in FV extract groups showed lower values than control group(P<0.05). The concentration of liver TNF-${\alpha}$ in FV extract groups showed a tendency to decrease and that of liver IL-10 in FV extract groups showed a tendency to increase; however, these values showed no significantly different. Conclusions : In inflammatory response by LPS derivation, the FV gives positive effect.

Interleukin-6 (IL-6), a central proinflammatory cytokine, maintains immune homeostasis and also plays important roles in cervical cancer. Therefore, we aimed to evaluate any associations of IL-6 gene polymorphisms at positions -174 and -572 with predisposition to cervical cancer in a Chinese population. The present hospital-based case-control study comprised 518 patients with cervical cancer and 518 healthy controls. Polymorphisms of the IL-6 gene were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Patients with cervical cancer had a significantly higher frequency of the IL-6 -174 CC genotype [odds ratio (OR) =1.52, 95% confidence interval (CI) = 1.06-2.19; p=0.02], IL-6 -572 CC genotype (OR =1.91, 95% CI = 1.16-3.13; p=0.01) and IL-6 -174 C allele (OR =1.21, 95% CI = 1.02-1.44; p=0.03) compared to healthy controls. When stratifying by the FIGO stage, patients with III-IV cervical cancer had a significantly higher frequency of IL-6 -174 CC genotype (OR =1.64, 95% CI =1.04-2.61; p=0.04). The CC genotypes of the IL-6 gene polymorphisms at positions -174 and -572 may confer a high risk of cervical cancer. Additional studies with detailed human papillomavirus (HPV) infection data are warranted to validate our findings.

Recombinant interleukin-2 (IL-2) has demonstrated as an antineoplastic agent in mice and human, but the relatively low response rates observed in clinical trials. Therefore, the present study was undertaken in order to evaluate therapeutic activities of IL-2 for the establishment of therapeutic applications. At the onset of the experiment, normal C3H/HeN mice were injected with $3{\times}10^6$ RD-995 tumor cells, murine ultraviolet radiation-induced fibrosarcoma, subcutaneously. Beginning on day 25, experimental groups were treated with a 5-day course of IL-2 (subcutaneous injection of 30,000 IU every 12 hours for 5 days). The result of this experiment revealed that RD-995 tumor grew progressively in control mice. Subcutaneous IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 therapy decreased tumor growth until day 23, then the tumor grew progressively. No significant difference in the survival of IL-2 treated mice were observed compared with the control mice.

In this report, we investigated the effect of aqueous extract of vinegar treated small black soybean (Glycine max Merr.) (Leguminosae) (VSBS) on mast cell-mediated allergic reaction and pro-inflammatory cytokine secretion. VSBS inhibited compound 48/80-induced systemic reactions. VSBS attenuated immunoglobulin (Ig) E-mediated passive cutaneous anaphylaxis. In addition, VSBS decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated secretion of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and interleukin (IL)-8 in human mast cells. Our findings provide evidence that VSBS inhibits mast cell-derived allergic reactions.
