  • Objective: Pathogenesis of the endometriosis is very complex and the etiology is still unclear. Our hypothesis is that there may be some difference in gene expression patterns between eutopic endometriums with or without endometriosis. In this study, we analyzed the difference of gene expression profile with cDNA microarray. Methods: Endometrial tissues were gathered from patients with endometriosis or other benign gynecologic diseases. cDNA microarray technique was applied to screen the different gene expression profiles from early and late secretory phase endometria of those two groups. Each three mRNA samples isolated from early and late secretory phase of endometrial tissues of control were pooled and used as master controls and labeled with Cy3-dUTP. Then the differences of gene expression pattern were screened by comparing eutopic endometria with endometriosis, which were labeled with Cy5-dUTP. Fluorescent labeled probes were hybridized on a microarray of 4,800 human genes. Results: Twelve genes were consistently over-expressed in the endometrium of endometriosis such as ATP synthase H transporting F1 (ATP5B), eukaryotic translation elongation factor 1, isocitrate dehydrogenase 1 (NADP+), mitochondrial ribosomal protein L3, ATP synthase H+ transporting (ATP5C1) and TNF alpha factor. Eleven genes were consistently down-regulated in the endometriosis samples. Many extracellular matrix protein genes (decorin, lumican, EGF-containing fibulin-like extracellular matrix protein 1, fibulin 5, and matrix Gla protein) and protease/protease inhibitors (serine proteinase inhibitor, matrix metalloproteinase 2, tissue inhibitor of metalloproteinase 1), and insulin like growth factor II associated protein were included. Expression patterns of selected eight genes from the cDNA microarray were confirmed by quantitative RT-PCR or real time RT-PCR. Conclusion: The result of this analysis supports the hypothesis that the endometrium from patients with endometriosis has distinct gene expression profile from control endometrium without endometriosis.

  • SMAD7 has been identified as a functional candidate gene for colorectal cancer (CRC). SMAD7 protein is a known antagonist of the transforming growth factor beta ($TGF-{\beta}$) signaling pathway which is involved in tumorigenesis. Polymorphisms in SMAD7 may thus alter cancer risk. The aim of this study was to investigate the influence of a SMAD7 gene polymorphism (rs2337107) on risk of CRC and clinicopathological features in an Iranian population. In total, 210 subjects including 105 patients with colorectal cancer and 105 healthy controls were recruited in our study. All samples were genotyped by TaqMan assay via an ABI 7500 Real Time PCR System (Applied Biosystems) with DNA from peripheral blood. The polymorphism was statistically analyzed to investigate the relationship with the risk of colorectal cancer and clinicopathological properties. Logistic regression analysis revealed that there was no significant association between rs2337107and the risk of colorectal cancer. In addition, no significant association between genotypes and clinicopathological features was observed (p value>0.05). Although there was not any association between genotypes and disorder, CT was the most common genotype in this population. This genotype prevalence was also higher in the patients with well grade (54.9%) and colon (72.0%) tumors. Our results provide the first evidence that this polymorphism is not a potential contributor to the risk of colorectal cancer and clinicopathological features in an Iranian population, and suggests the need of a large-scale case-control study to validate our results.

  • Inflammatory mediators has been recognized as an important role in the pathogenesis of rheumatoid arthritis (RA). IL-17 is increasingly recognized as an important regulator of immune and inflammatory responses, including induction of proinflammatory cytokines and osteoclastic bone resorption. Evidence of the expression and proinflammatory activity of IL-17 has been demonstrated in RA synovium and in animal models of RA. However, the signaling pathways that regulate IL-17 production remain unknown. In the present study, we investigated the role of the phosphatidylinositol 3 kinase (PI3K)-Akt pathway in the regulation of IL-17 production in RA. PBMC were separated from RA (n=24) patients, and stimulated with various agents (anti CD3, anti CD28, PHA, ConA, IL-15). IL-17 levels were determined by sandwich ELISA and RT-PCR. The production of IL-17 was significantly increased in cells treated with anti-CD3 antibody, PHA, IL-15 or MCP-1 (P<0.05). ConA also strongly induced IL-17 production (P<0.001), whereas TNF-alpha, IL-1beta, IL-18 or TGF-beta did not. IL-17 was detected in the PBMC of patients with osteoarthritis (OA) but their expression levels were much lower than those of RA PBMC. Anti-CD3 antibody activated the PI3K-Akt pathway and activation of the PI3K-Akt pathway resulted in a pronounced augmentation of nuclear factor kappaB ($NF-{\kappa}B$). IL-17 production by activated PBMC in RA is completely or partially blocked in the presence of $NF-{\kappa}B$ inhibitor PDTC and PI3K-Akt inhibitor, wortmannin and LY294002, respectively. Whereas the inhibition of AP-1 and extracellular signal-regulated kinase (ERK)1/2 did not affect IL-17 production. These results provide new insight into that PI3K/Akt and $NF-{\kappa}B$ dependent signal transduction pathway could be involved in the overproduction of key inflammatory cytokine, IL-17 in rheumatoid arthritis.

  • Bone morphogenetic protein-2/4 (BMP-2/4) are members of Transforming Growth $Factor-{\beta}\;(TGF-{\beta})$ superfamily and they may differentiate the osteoprogenitor cell and induce formation of cartilage and bone in vivo. This study was performed to investigate the effects of bone morphogenetic protein-2/4 on the characteristics of rat periodontal ligament cells(RPDL) and rat calvaria cells(RCV). In the control group, the cells were cultured alone with Dulbeco's Modified Eagle's Medium contained with 20% fetal bovine serum, $100{\mu}/ml$ penicillin, $100{\mu}/ml$ streptomycin. In the experimental groups, recombinant human bone morphogenetic protein-2/4 (25ng, 100ng, 250ng/ml) were added into the above culture condition. And then each group was characterized by examing the cell proliferation at 1, 2, 3, 5, 7th day, the amount of total protein synthesis and alkaline phosphatase activity at 2, 5, 7th day. And also, the calcified nodule was examed. The results were as follows ; 1 . Both RCV and RPDL cells in both control and experimental groups proliferated during the entire experimental period, but there is no stastically significant difference according to the BMP-2/4 concentration. 2 . Amount of total protein synthesis of both cells in both groups was steadily increased until 5th day, but all experimental groups were significantly different from the control group at 7th day. 3. Alkaline phosphatase activity of both cells in both groups was increased during the entire experiment period. In RCV cells, the experimental group treated with 100ng/ml and 250ng/ml BMP-2/4 were significantly different from the control group at 7th day. In RPDL cells, the experimental group treated with 100ng/ml and 250ng/ml BMP-2/4 were significantly different from the control group at 5th day, and all experimental groups were significantly different from the control group at 7th day. 4. In the both of the cultured Rat Periodontal ligament and calvaria cell treated with BMP-2/4 to compared with control group, it revealed more rapid cell polarization, cell aggregation and hyperchromatic stained on HE agent, and even though only 1 day treated with BMP-2/4 both RPDL and RCV showed more rapid cell reaction than control group. More sensivitve cell reaction of RCV were observed than RPDL in this experiment. From the above results, we could conclude that BMP-2/4 influenced the induction, proliferation and differentiation of bone forming cells

  • Objectives: Trans-cinnamaldehyde (TCA) is the main component of Cinnamomi Ramulus and it has been reported that TCA inhibits inflammatory responses in various cell types. Inflammation-mediated neurological disorders induce the activation of macrophages such as microglia in brain, and these activated macrophages release various inflammation-related molecules, which can be neurotoxic if overproduced. In this study, we evaluated gene expression profiles using gene chip microarrays in lipopolysaccharide (LPS)-stimulated BV-2 cells to investigate the antiinflammatory effect of TCA on inflammatory responses in brain microglia. Methods: A negative control group was cultured in normal medium and a positive control group was stimulated with $1{\mu}g/ml$ in the absence of TCA. TCA group was pretreated with $10{\mu}g/ml$ before $1{\mu}g/ml$ LPS stimulation. The oligonucleotide microarray analysis was performed to obtain the expression profiles of 28,853 genes using gene chip mouse gene 1.0 ST array in this study. Results: In positive control group, 1522 probe sets were up-regulated in the condition of the cutoff value of 1.5-fold change and 341 genes with Unigene ID were retrieved. In TCA group, 590 probe sets were down-regulated from among 1522 probe sets and 33 genes with Unigene ID were retrieved, which included 6 inflammation-related genes. We found out that Id3 gene is associated with transforming growth factor-${\beta}$ (TGF-${\beta}$) signaling pathway and Klra8 gene is related to natural killer cell-mediated cytotoxicity pathway. Conclusions: The results mean that TCA inhibits inflammatory responses through down-regulating the expressions of inflammation-related genes in LPS-stimulated BV-2 cells.

  • Bone morphogenetic proteins(BMPs) are a group of transforming growth factor beta(TGF-${\beta}$)-related factors and multifunctional proteins, especially the only known biologic factors capable of inducing endochondral bone formation at an extraskeletal site. This study was performed to investigate the effect of the partially purified porcine BMP(pBMP) at an ectopic site. PBMP was partially purified from porcine bone matrix and its activity was monitored by an in vivo bioassay. The purification method utilized extraction of the bone-inducing activity with 4M guanidine, followed by chromatography on heparin-Sepharose. Active fractions were assayed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. And the fractions were reconstituted with inactive insoluble collagenous bone matrix from rats, acid soluble type I collagen from rat tail and chondroitin-6-sulfate sodium salt and implanted into the pectroralis muscle pouches of Sprague-Dawley rats. And the carrier complex was implanted on the opposite side as control. The rats were sacrificed at the day of 1st, 3rd, 5th, 7th, 11th, 14th and 21st after implantation and examined histologically, radiologically and biochemically. And alkaline phosphatase activity and calcium content were used as indices of bone formation. The results were as follows ; 1. Active fractions were localized in a zone between 31 and 40 KDa on SDS-PAGE. 2. The implanted 3.0mg of the partially purified pBMP induced cartilage and bone in the muscle tissue of rats through an endochondral ossification process. 3. Inactive insoluble bone matrix, type I collagen and chondroitin-6-sulfate have functioned as carriers for pBMP, but revealed some foreign body reactions. 4. Soft X-ray didn't reveal significant change between the experimental and the control group. 5. The alkaline phosphatase activities in the experimental group of 5th, 7th, 11th, 14th and 21st were increased significantly compared with control (p<0.01) with the peak in the group of 11th day. 6. With time, the calcium content of the experimental group increased. And the calcium contents in the experimental group of 11th, 14th and 21st were increased significantly compared with control (p<0.01).

  • Wished to examine closely effect that SoPungDoJeokTang-KaMi (SPDJTK) medicines used to atopy dermatitis disease patient get in atopy eruption control experimentally. SPDJTK medicines controlled $CD4^+/IFN-\gamma$, and $CD4^+/CD25^+/foxp3^+$ revelation that an experiment that motive allergy immune reponse because an in vitro experiment stimulates T cells of a NC/Nga mouse same time by anti-CD40/rmIL-4, and interleukin-$1{\beta}$, IL-6, TNF-$\alpha$, and TGF-$\beta$ mRNA outturn that bear in T and B cells decreased remarkably by SPDJTK medicines. Intracellular staining of splenocytes anti-CD40/rmIL-4 plus rmIL-4 stimulated as described in a, assessed after 24 h, SPDJTK exerts a mainly immunosuppressive effect that acts at least partially through suppression of the transcription factor GATA3 expression in $CD4^+$ T cells. Atopic dermatitis (AD) usually develops in patients with an individual or family history of allergic diseases, and is characterized by chronic relapsing inflammation seen specially in childhood, association with IgE hyperproduction and precipitation by environmental factors. However, the exact etiology of AD has been unclear. To further explore the pathogenesis and treatment of AD, a suitable animal model is required. We found that skin lesions, which were clinically and histologically very similar to human AD, mite antigen-induced dermatitis on the face, neck, ears and dorsal skin of inbred NC/Nga mice. Result that Th1 cell and Th2 cell observe to be shifted by cytokine expression with $CD4^+/CD25^+/foxp3^+$ Treg cells induction by SPDJTK medicines could know that SPDJTK medicines can use usefully in allergy autoimmnune diease.

  • Objectives: The stomach is a sensitive digestive organ that is susceptible to exogenous pathogens from the diet. In response to such pathogens, the stomach induces oxidative stress, which might be related to the development of both gastric organic disorders such as gastritis, gastric ulcers, and gastric cancer, and functional disorders such as functional dyspepsia. This study was accomplished to investigate the effect of Ganoderma lucidum pharmacopuncture (GLP) on chronic gastric ulcers in rats. Methods: The rats were divided into 4 groups of 8 animals each: the normal, the control, the normal saline (NP) and the GLP groups. In this study, the modified ethanol gastritis model was used. The rats were administrated 56% ethanol orally every other day. The dose of ethanol was 8 g/kg body weight. The normal group received the same amount of normal saline instead of ethanol. The NP and the GLP groups were treated with injection of saline and GLP respectively. The control group received no treatment. Two local acupoints CV12 (中脘) and ST36 (足三里) were used. All laboratory rats underwent treatment for 15 days. On last day, the rats were sacrificed and their stomachs were immediately excised. Results: Ulcers of the gastric mucosa appeared as elongated bands of hemorrhagic lesions parallel to the long axis of the stomach. In the NP and GLP groups, the injuries to the gastric mucosal injuries were not as severe as they were in the control group. Wound healings of the chronic gastric ulcers was promoted by using GLP and significant alterations of the indices in the gastric mucosa were observed. Such protection was demonstrated by gross appearance, histology and immunehistochemistry staining for Bcl-2-associated X (BAX), B-cell lymphoma 2 (Bcl-2) and Transforming growth factor-beta 1 (TGF-${\beta}1$). Conclusion: These results suggest that GLP at CV12 and ST36 can provide significant protection to the gastric mucosa against an ethanol induced chronic gastric ulcer.

  • Many biological systems are regulated by an intricate set of feedback loops that oscillate with a circadian rhythm of roughly 24 h. This circadian clock mediates an increase in body temperature, heart rate, blood pressure, and cortisol secretion early in the day. Recent studies have shown changes in the amplitude of the circadian clock in the hearts and livers of streptozotocin (STZ)-treated rats. It is therefore important to examine the relationships between circadian clock genes and growth factors and their effects on diabetic phenomena in animal models as well as in human patients. In this study, we sought to determine whether diurnal variation in organ development and the regulation of metabolism, including growth and development during the juvenile period in rats, exists as a mechanism for anticipating and responding to the environment. Also, we examined the relationship between changes in growth factor expression in the liver and clock-controlled protein synthesis and turnover, which are important in cellular growth. Specifically, we assessed the expression patterns of several clock genes, including Per1, Per2, Clock, Bmal1, Cry1 and Cry2 and growth factors such as insulin-like growth factor (IGF)-1 and -2 and transforming growth factor (TGF)-${\beta}1$ in rats with STZ-induced diabetes. Growth factor and clock gene expression in the liver at 1 week post-induction was clearly increased compared to the level in control rats. In contrast, the expression patterns of the genes were similar to those observed after 5 weeks in the STZ-treated rats. The increase in gene expression is likely a compensatory change in response to the obstruction of insulin function during the initial phase of induction. However, as the period of induction was extended, the expression of the compensatory genes decreased to the control level. This is likely the result of decreased insulin secretion due to the destruction of beta cells in the pancreas by STZ.
