The cholangiocarcinoma (CCA) is a relatively rare cancer worldwide but it is highly prevalent in Thailand where the liver fluke, Opisthorchis viverrini is endemic. There are reports that interleukin 6 (IL-6) may play an important role in the pathogenesis of opisthorchiasis associated CCA. Functionally, IL-6 can act on target cells through its receptor, IL-6R, and IL-6R polymorphisms may affect the functional activity of IL-6 leading to susceptibility to cholangiocarcinogenesis. Therefore, we assessed the association of the 48892 A/C (Asp358Ala) polymorphism in exon 9 of the IL-6R gene in 79 CCA cases compared to 80 healthy controls using the PCR-RFLP technique. The results showed significant differences between CCA cases and controls in overall genotype (p=0.001) and allele frequencies (p=0.0002). Chi-square for trend test revealed a significant association between genotype and CCA susceptibility (p=0.0002). The odds ratios (ORs) for genotype were 0.283 (95% CI=0.131-0.605, AC vs. AA; p=0.0003) and 0.206 (95% CI=0.196-1.245, CC vs. AA; p=0.0416), the OR for alleles was 0.347 (95% CI=0.187-0.633, allele C vs. allele A; p=0.0002) and that for the carrier C variant was 0.272 (95% CI=0.130-0.564; p=0.0001). This study demonstrated a close association between an IL-6R polymorphism, specifically higher A allele, and cholangiocarcinoma.

Nutrigenomics refers to research that investigates the interaction between nutrition and the human genome. Caffeine in tea and coffee is widely and routinely consumed by people. This study was performed to confirm the effect of caffeine treatment on the gene expression and cytokine profiling in 3T3-L1 adipocyte cells using microarray and protein array methodology. Treatment of caffeine in 3T3-L1 adipocyte cells increased expression of several genes related with obesity including adipocyte C1Q and collagen domain containing (ACDC), Adipsin (ADN), uncoupling protein 3(UCP3), while glyceraldehyde-3-phosphate dehydrogenase (GAPDH), which is known as lipid storage enzyme, was decreased by caffeine treatment. Furthermore, cytokines, such as interleukin-3 (IL-3), interleukin-12(IL-12), interleukin-13 (IL-13), granulocyte colony stimulating factor (GCSF), granulocyte macrophage colony stimulating factor (GM-CSF) and vascular endothelial growth factor (VEGF), were decreased in caffeine treated 3T3-L1 adipocyte cells. These results provided interesting information about the genes related with caffeine and cytokine expression profiling in obesity.

Background: The present study was designed to prepare and find the optimum active preparation or fraction from Korea Red Ginseng inhibiting matrix metalloproteinase-13 (MMP-13) expression, because MMP-13 is a pivotal enzyme to degrade the collagen matrix of the joint cartilage. Methods: From total red ginseng ethanol extract, n-BuOH fraction (total ginsenoside-enriched fraction), ginsenoside diol-type-enriched fraction (GDF), and ginsenoside triol-type-enriched fraction (GTF) were prepared, and ginsenoside diol type-/F4-enriched fraction (GDF/F4) was obtained from Panax ginseng leaf extract. Results: The n-BuOH fraction, GDF, and GDF/F4 clearly inhibited MMP-13 expression compared to interleukin-$1{\beta}$-treated SW1353 cells (human chondrosarcoma), whereas the total extract and ginsenoside diol-type-enriched fraction did not. In particular, GDF/F4, the most effective inhibitor, blocked the activation of p38 mitogen-activated protein kinase (p38 MAPK), c-Jun-activated protein kinase (JNK), and signal transducer and activator of transcription-1/2 (STAT-1/2) among the signal transcription pathways involved. Further, GDF/F4 also inhibited the glycosaminoglycan release from interleukin-$1{\alpha}$-treated rabbit cartilage culture (30.6% inhibition at $30{\mu}g/mL$). Conclusion: Some preparations from Korean Red Ginseng and ginseng leaves, particularly GDF/F4, may possess the protective activity against cartilage degradation in joint disorders, and may have potential as new therapeutic agents.

Interleukin-18 (IL-18) is an immune-stimulatory cytokine with antitumor activity in preclinical models. It plays pivotal roles in linking inflammatory immune responses and tumor progression and is a useful candidate in gene therapy of lymphoma or lymphoid leukemia. A phase I study of recombinant human IL-18 (rhIL-18) in patients with advanced cancer concluded that rhIL-18 can be safely given in biologically active doses to patients with advanced cancer. Some viruses can induce the secretion of IL-18 for immune evasion. The individual cytokine activity might be potentiated or inhibited by combinations of cytokines. Here we focus on combinational effects of cytokines with IL-18 in cancer progression. IL-18 is an important non-invasive marker suspected of contributing to metastasis. Serum IL-18 may a useful biological marker as independent prognostic factor of survival. In this review we cover roles of IL-18 in immune evasion, metastasis and angiogenesis, applications for chemotherapy and prognostic or diagnostic significance.

In the present study, effects of interleukin-2 (IL-2), a differentiator and proliferator of T-cells, on nuclear maturation and sperm penetration of bovine oocytes was examined in a serum-free or serum-containing medium. Basic medium was used TCM-199 supplemented with 2.2g / ι sodium bicarbonate, 100 i.u. /rnl penicillin. 100$\mu$g /ml streptomycin, 0.25$\mu$g/ml Fungizone, this medium treated with FCS and IL-2. In experiment 1, we examined the effect of the addition of 0, 1, 5, 10 or 15nM /ml IL-2 to tissue culture medium (TCM-199) on nuclear maturation of oocytes Development of oocytes to the Metaphase II (M II) stage (%) was significantly (P<0.05) higher at 1, 5,10 and 15 nM /ml IL-2(54.2, 73.5, 80.0 and 69.6%, respectively) than at 0 nM /ml IL-2(35.7%). In experiment 2, we examined the effect of the addition of l0nM /ml IL-2 or 5% FCS in oocyte maturation. Nuclear maturation rates were significantly(P<0.05) higher l0nM /ml IL-2(80%) than non-treatment(35.7%) and 5% FCS(63.6%) treatment. On the other hand, there were no significant difference in the proportion of oocytes developed to the 2-cell stage after addition of IL-2 and/or FCS. These results suggest that IL-2 supports nuclear maturation of bovine immature oocytes in vitro. Serum-free maturation system using IL-2 might be useful for evaluation of various factors on oocyte maturation.

Background : Several studies have suggested that alterations of cytokine level could be related to the pathophysiology of bipolar disorder. In this study, we measured plasma level of Interleukin-12(IL-12), a pro-inflammatory cytokine and transforming growth factor-${\beta}$1(TGF-${\beta}$1), an anti-inflammatory cytokine before and after treatment in acute manic patients. Methods : The plasma concentrations of IL-12 and TGF-${\beta}$1 were measured using quantitative ELISA in 18 bipolar disorder patients and 25 normal controls at admission and 6 weeks later. The psychopathology was measured by Brief Psychiatric Rating Scale(BPRS) and Young Mania Rating Scale(YMRS). Results : IL-12 levels were significantly higher in bipolar manic patients than in controls before treatment. Following the 6-week treatment, the IL-12 level was decreased than before treatment, but sustained still higher level than normal control. TGF-${\beta}$1 level was not significant different between manic patients and normal controls before treatment, but was increased after treatment comparing with before treatment in bipolar patients. The ratio of IL-12 and TGF-${\beta}$1 was significantly decreased after treatment. Conclusion : Cytokine abnormalities in bipolar disorder might be involved in the pathophysiology of the illness. It is possible that TGF-${\beta}$1 plays an important role in the regulation of immunological imbalance in bipolar disorder.

Osteoarthritis (OA) is one of the most prevalent degenerative joint diseases and is more common in older and obese individuals. Silkworm male pupae exerts tonic effects by increasing testosterone secretion and the forced swimming time and muscle ratio increased in mice consuming silkworm pupae, which may be beneficial to the older population. Therefore, it will be beneficial to investigate the effects of silkworm pupal extracts (SPE) on OA. To confirm this effect, we prepared SPE in different solvents, and their ability to attenuate matrix metalloproteinases (MMPs) and inflammatory mediators (interleukin-6 [IL-6], interleukin-8 [IL-8] and tumor necrosis factor-α [TNF-α]) were evaluated in an interleukin-1β (IL-1β)-induced SW1353 human chondrosarcoma cell line. 70% ethanolic SPE outperformed the other solvents, reducing MMP-1 and MMP-3 expression by up to 53% and 13%, respectively. Further experiments were performed using 70% ethanolic SPE from three distinct pupation stages in males and females. SPE treatment alleviated MMP-1 expression (43.9-47.4%) regardless of pupation stage and sex. Among the inflammatory mediators, 70% ethanolic SPE alleviated IL-6 and TNF-α levels, and the concentrations thereof were lowest in the early-stage male SPE-treated group (43.15% and 56.74%, respectively). In conclusion, 70% ethanolic SPE may prevent IL-1β-induced osteoarthritis by inhibiting MMPs and inflammatory cytokines. Therefore, SPE is a potential therapeutic agent for the treatment of OA.

The anaphylactic allergic reaction is involved in many allergic diseases such as asthma and allergic rhinitis. In this report, I investigated the effect of ripe fruits of Rubus coreanus Miq. (Rosaceae) (RFRC) on the anaphylactic allergic reaction and studied its possible mechanisms of action. RFRC inhibited compound 48/80-induced systemic anaphylactic reaction in mice. RFRC dose-dependently decreased the IgE-mediated passive cutaneous anaphylaxis. In addition, RFRC decreased the gene expression and production of tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and interleukin (IL)-6 in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (A23187)-stimulated human mast cells. These findings provide evidence that RFRC could be a candidate as an anti-allergic agent.

The purpose of this research was to investigate the effects of Seungyangikkitang (SIT) on the immune cells in BALB/c mice. SIT (500mg/kg) was administerd p.o. once a day for 7 days. SIT enhanced the proliferation of thymocytes, but decreased the proliferation of splenocytes. SIT enhanced the subpopulation of cytotoxic T cells in thymocytes and helper T cells in splenocytes, but did not affect the subpopulation of B220/Thy1 cells. SIT enhanced the production of γ-interferon and interleukin-2 in thymocytes, splenocytes and serum, but did not affect the production of interleukin-4. SIT suppressed the production of nitric oxide, but enhanced the lucigenin chemiluminescence and the engulfment of FITC-conjugated E. coli particles in peritoneal macrophages. These results suggest that SIT has a potent activity on the specific immunity via the cytokine secretion of Th1 cells and the non-specific immunity via the phagocytic activity of macrophages in vivo.
