Objectives : Pro-inflammatory cytokines are related to the pathophysiology of both cancer and depression, and their secretion is controlled by the transcriptional activity of particular gene polymorphisms. This study aimed to investigate whether interleukin (IL)-1β -511C/T gene polymorphism is associated with depression following mastectomy for breast cancer. Methods : A total of 309 patients with breast cancer were evaluated one week after mastectomy, and 244 (79%) were followed one year later. Depression (major+minor depressive disorders) was diagnosed according to DSM-IV criteria using the Mini International Neuropsychiatric Interview, and classified into prevalent, persistent, and incident depression. Associations of IL-1β -511C/T polymorphism with the three depressive status were estimated using logistic regression models. Results : At baseline, 74 (24%) patients were classified with prevalent depression ; and at follow up, 19 (8%) and 25 (10%) patients were classified with persistent and incident depression, respectively. The IL-1β -511T/T genotype was independently associated with prevalent and persistent depression, but not with incident depression. Conclusion : IL-1β -511T/T genotype may involve in the etiology of depression occurring in women with breast cancer who receive a mastectomy.

Objectives: Gallic acid (GA) is the major component of tannin which could be easily founded in various natural materials such as green tea, red tea, grape juice, and Corni Fructus. The purpose of this study is to investigate the effect of Gallic acid (GA) on production of interleukin (IL) in mouse macrophage Raw 264.7 cells stimulated by lipopolysaccharide (LPS). Methods: Productions of interleukins were measured by High-throughput Multiplex Bead based Assay with Bio-plex Suspension Array System based on $xMAP^{(R)}$ (multi-analyte profiling beads) technology. Firstly, cell culture supernatant was obtained after treatment with LPS and GA for 24 hour. Then, it was incubated with the antibody-conjugated beads for 30 minutes. And detection antibody was added and incubated for 30 minutes. And Strepavidin-conjugated Phycoerythrin (SAPE) was added. After incubation for 30 minutes, the level of SAPE fluorescence was analyzed on Bio-plex Suspension Array System and concentration of interleukin was determined. Results: The results of the experiment are as follows. 1. GA significantly inhibited the production of IL-3, IL-10, IL-12p40, and IL-17 in LPS-induced mouse macrophage RAW 264.7 cells at the concentration of 25, 50, 100, 200 uM (p<0.05). 2. GA significantly inhibited the production of IL-6 in LPS-induced mouse macrophage RAW 264.7 cells at the concentration of 50, 100, 200 uM (p<0.05). 3. GA diminished the production of some cytokine such as IL-4, IL-5, and IL-13 in LPS-induced mouse macrophage RAW 264.7 cells. 4. GA did not show the inhibitory effect on the production of IL-$1{\alpha}$ and IL-9 in LPS-induced mouse macrophage RAW 264.7 cells. Conclusions: These results suggest that GA has anti-inflammatory activity related with its inhibitory effects on the production of interleukins such as IL-3, IL-10, IL-12p40, IL-17, and IL-6 in LPS-induced macrophages.

Objective : There are many reports that acupuncture has thermoregulatory effects on human and animals. To investigate the effect and mechanism of antipyretic action of acupuncture, we observed the body temperature and cytokine expressions in the hypothalamus of rats. Methods : Lipopolysaccharide (LPS, i.p., 2.5mg/kg) was injected to conscious rats (Sprague-Dawley, male, n=4l) to cause hyperthermia and simple needling (stainless steel, 0.25 mm o.d., 5 mm insertion for 10 sec with no manipulation) was performed bilaterally with the measurement of rectal temperature. Next, we sacrificed rats to remove brain and determined the level of mRNA for interleukin-6 (IL-6), $interleukin-1{\beta}{\;}(IL-1{\beta})$, interleukin-2 (IL-2) and $interferon-{\gamma}{\;}(IFN-{\gamma})$ in the hypothalamus by using reverse transcriptase-polymerase chain reaction (RT-PCR). Resul1s : Needling on forepaw (acupoint HT8) and needling on hindpaw (acupoint BL66 and acupoint LR2) significantly inhibited LPS-induced fever of rats (P<0.01, 10 min after treatment respectively), but same treatment on proximal tail (non-acupoint) did not cause any change on fever. The levels of IL-6 and $IL-1{\beta}$ mRNA in the hypothalamus was significantly enhanced by LPS-injection, while the level of IL-6 and $IL-1{\beta}$ mRNA was markedly reduced after treatment on BL66 (P<0.01). Treatment on forepaw reduced it slightly, but not significantly. Equivalent stimulation on proximal tail did not cause any changes. Conclusions : Our results indicate that acupuncture stimulation on various body parts has differential thermoregulatory effects on LPS-induced fever of rats with site-specificity. And, we suggest that its antipyretic action might be accompanied with the suppression of hypothalamic production of pro-inflammatory cytokine of immune system, IL-6 and $IL-1{\beta}$.

본 논문에서는 혈관내피세포에서 저농도의 트롬빈이 TNF-$\alpha$가 NF-kB의 활성화를 통해 생성되는 IL-6의 생성량에 미치는 영향을 관찰하였다. TNF-$\alpha$는 혈관내피세포에서 NF-kB의 활성화를 통해 염증을 유발시킨다는 것은 잘 알려진 사실이다. 이 논문에서는 TNF-$\alpha$가 매개하는 염증작용에서 저농도의 트롬빈은 TNF-$\alpha$가 생성시키는 IL-6의 생성량을 감소시켰고, 여기에는 트롬빈의 수용체인 PAR-1이 작용하다는 것을 확인하였다. 뿐만 아니라, 세포내의 PI3-Kinase 역시 저농도 트롬빈이 관여한다는 것을 확인하였다. 이것은 저농도의 트롬빈이 수용체인 PAR-1을 활성화시키고, 활성화된 PAR-1 은 PI3-Kinase의 활성화을 통해 항염증작용을 보여준디는 것을 의미한다. 이 결과는 향후 중증 패혈증 및 각종 염증질환을 치료할 수 있는 신약개발에 있어 중요한 단서를 제공하고 혈관내피세포에서 아직 명확하게 밝혀지지 않은 트롬빈의 염증작용 및 항염증작용의 기전을 밝히는데 좋은 정보를 제공할 것이다.

Novel chalcones were found as potent inhibitors of interleukin-5 (II-5). 1-(6-Benzyloxy-2-hydroxyphenyl)-3-(4-hydroxyphenyl)propenone (2a, 78.8% inhibition at $50\;{\mu}M,\;IC_{50}=25.3\;{\mu}M$) was initially identified as a potent inhibitor of IL-5. This activity is comparable to that of budesonide or sophoricoside (1a). The benzyloxy group appears to be critical for the enhancement of the IL-5 inhibitory activity. To identify the role of this hydrophobic moiety, cyclohexyloxy (2d), cyclohexylmethoxy (2c), cyclohexylethoxy (2e), cyclohexylpropoxy (2f), 2-methylpropoxy (2g), 3-methylbutoxy (2h), 4-methylpentoxy (2i), and 2-ethylbutoxy (2j) analogs were prepared and tested for their effects on IL-5 bioactivity. Compounds 2c ($IC_{50}=12.6\;{\mu}M$), 2d ($IC_{50}=12.2\;{\mu}M$), and 2i ($IC_{50}=12.3\;{\mu}M$) exhibited the most potent activity. Considering the cLog P values of 2, the alkoxy group contributes to the cell permeability of 2 for the enhancement of activity, rather than playing a role in ligand motif binding to the receptor. The optimum alkoxy group in ring A of 2 should be one that provides the cLog P of 2 in the range of 4.22 to 4.67.

Background/Aims: Several epidemiological studies have validated the association of interleukin gene polymorphisms with acute pancreatitis (AP) in different populations. However, there have been few studies in Asian ethnic groups. We aimed to investigate the relationships between inflammatory cytokine polymorphisms and AP as pilot research in a Korean ethnic group. Methods: Patients who had been diagnosed with AP were prospectively enrolled. DNA was extracted from whole blood, and DNA sequencing was subsequently performed. Single-nucleotide polymorphisms (SNPs) of the interleukin $1{\beta}$ (IL1B), interleukin 1 receptor antagonist (IL1RN), and tumor necrosis factor ${\alpha}$ (TNFA) genes of patients with AP were compared to those of normal controls. Results: Between January 2011 and January 2013, a total of 65 subjects were enrolled (40 patients with AP vs. 25 healthy controls). One intronic SNP (IL1RN -1129T>C, rs4251961) was significantly associated with the risk of AP (odds ratio, 0.304; 95% confidence interval, 0.095 to 0.967; p = 0.043). However, in our study, AP was not found to be associated with polymorphisms in the promoter regions of inflammatory cytokine genes, including IL1B (-118C>T, c47+242C>T, +3954C/T, and -598T>C) and TNFA (-1211T>C, -1043C>A, -1037C>T, -488G>A, and -418G>A). Conclusions: IL1RN -1129T>C (rs4251961) genotypes might be associated with a significant increase of AP risk in a Korean ethnic group.

Background: A previous study reported that hyperlipidemia increases the incidence of tears in the rotator cuff tendon and affects healing after repair. The aim of our study was to compare the gene and protein expression of torn rotator cuff tendons in patients both with and without hypercholesterolemia. Methods: Thirty patients who provided rotator cuff tendon samples were classified into either a non-hypercholesterolemia group (n=19, serum total cholesterol [TC] <200 mg/dL) and hypercholesterolemia group (n=11, serum TC ≥240 mg/dL) based on their concentrations of serum TC. The expression of various genes of interest, including COL1A1, IGF1, IL-6, MMP2, MMP3, MMP9, MMP13, TNMD, and TP53, was analyzed by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). In addition, Western blot analysis was performed on the proteins encoded by interleukin (IL)-6 and TP53 that showed significantly different expression levels in real-time qRT-PCR. Results: Except for IGF1, the gene expression levels of IL-6, MMP2, MMP9, and TP53 were significantly higher in the hypercholesterolemic group than in the non-hypercholesterolemia group. Western blot analysis confirmed significantly higher protein levels of IL-6 and TP53 in the hypercholesterolemic group (p<0.05). Conclusions: We observed an increase in inflammatory cytokine and matrix metalloproteinase (MMP) levels in hypercholesterolemic patients with rotator cuff tears. Increased levels of IL-6 and TP53 were observed at both the mRNA and protein levels. We suggest that the overexpression of IL-6 and TP53 may be a specific feature in rotator cuff disease patients with hypercholesterolemia.
