In this study, we confirmed the effect of HK shiitake mushroom mycelium (HKSMM) on immune enhancement in Balb/c mice. Experimental animals were divided into five groups: negative control (NC), positive control (PC; 1,000 mg/100 g; AHCC), T1 (500 mg/100 g; HKSMM), T2 (1,000 mg/100 g; HKSMM), and T3 (2,000 mg/100 g; HKSMM), and dissection was performed at four and six weeks. COX-2 and iNOS concentrations were significantly lower in the six-week experimental group than in the control group, and the NO results were also similar. Results of the confirmation of the factors related to the NF-κB (p-p65 and p-IκBα) and MAPK (pERK, pJNK, and p38) signaling pathways revealed that the HKSMM-fed experimental group significantly decreased compared with the control group. A comparative analysis of the number and size of white pulp in the spleen tissue showed that those of the experimental group were significantly higher than those of the control group in a concentration-dependent manner. These results suggest that HKSMM has both immune-enhancing and anti-inflammatory effects in Balb/c mice, indicating that it can be used as a health functional food ingredient.
Objectives Forsythiae Fructus treatment has been used for inflammatory and allergic diseases in Korean Medicine. Nevertheless, the mechanism of action and the cellular targets are not understood well. The pathogenesis of allergic diseases are associated with Th2 cytokines such as IL-13, MIP-$1{\alpha}$, IL-13, IL-5, GM-CSF, IL-4, TNF-${\alpha}$ and IL-6, which are secreted by the mast cells. This study was conducted to investigate the effects of Forsythiae Fructus extracts (FF) on Th2 cytokines expression and signal transduction in MC/9 mast cells. Methods In the study, MC/9 mast cells were stimulated with DNP-IgE for 24 hours and then treated separately with CsA $10{\mu}g/m{\ell}$ and varying doses of FF for one hour. MC/9 mast cells stimulated with DNP-IgE was the control group, a treatment with CsA was the positive control group and a treatment with varying doses FF was the experimental groups. The mRNA levels of IL-13, IL-5, GM-CSF, IL-4, TNF-${\alpha}$, IL-6 were analyzed with Real-time PCR. The levels of IL-13, MIP-$1{\alpha}$ were measured using enzyme-linked immunosorbent assays(ELISA). NFAT, AP-1 and NF-${\kappa}B$ p65 were examined by Western blot analysis. Results 1. FF were observed to suppress the mRNA expression of IL-13, IL-5, GM-CSF, IL-4, TNF-${\alpha}$, IL-6 in comparison to DNP-IgE control group. 2. FF also has inhibited the IL-13, MIP-$1{\alpha}$ production significantly in comparison to DNP-IgE control group. 3. Western blot analysis of transduction factors involving Th2 cytokines expression has revealed a prominent decrease of the mast cell specific transduction factors including NFAT-1, NFAT-2, c-Jun, and NF-${\kappa}B$ p65 but c-Fos. Conclusions In conclusion, the anti-allergenic activities of FF may be strongly related to the regulation of transcription factors NFAT-1, NFAT-2, c-Jun, and NF-${\kappa}B$ p65 causing inhibition of Th2 cytokines in mast cells.

Objectives The purpose of this study is to investigate the effects of Gardenia jasminoides for. grandiflora extracts' (GAJ) anti-inflammatory effect on RBL-2H3 mast cells and OVA/alum-sensitized mice. Methods In this study, IL-4 and IL-13 production was measured via ELISA analysis, and mRNA expressions of GM-CSF, IL-4, IL-5, $TNF-{\alpha}$, IL-6 were analyzed by real-time PCR. In addition, MAPKs and $NF-{\kappa}B$ p65 transcription factors were examined using western blotting, and ELISA was used to understand IgE, IL-4, and IL-13 production in ovalbumin-allergic mice in in vitro study. Results As a result of this study, 1. GAJ were observed to suppress the mRNA expression of GM-CSF, IL-4, IL-13, IL-5, $TNF-{\alpha}$, IL-6 in comparison to PMA 50 ng/ml, ionomycin $0.5{\mu}M$ (PI) control group. 2. GAJ also inhibited the IL-4, IL-13 production in comparison to PI control group. 3. Western blot analysis showed decrease on the expression of mast-cell-specific transcription factors, including MAKPs (ERK, JNK, p38) and $NF-{\kappa}B$ p65. 4. Orally-administered GAJ group in OVA/alum induced Balb/c mice showed decreased level of OVA-specific IgE in the serum. This group also has shown decreased the level of IL-4, IL-13 in the splenocyte culture supernatant. Conclusions Obtained results suggest that GAJ may regulate the allergic inflammation by transcription factors MAKPs (ERK, JNK, p38) and $NF-{\kappa}B$ p65 causing inhibition of Th2 cytokines in mast cells and OVA/alum-sensitized mice.

Obesity, which is characterized by a state of mild chronic inflammation, is known to cause metabolic diseases. This study was carried out to investigate the effect of lyophilized dropwort vinegar powder (DVP) on adipocyte differentiation and inflammation in T3-L1 preadipocyte and RAW 264.7 macrophage cell lines. DVP inhibited the differentiation of 3T3-L1 preadipocytes induced by a mixture of IBMX, dexamethasone, and insulin (MDI). Western blot analysis of cell lysates showed that DVP decreased the levels of two major transcription factors involved in adipogenesis, peroxisome proliferator- activated receptor-${\gamma}$ (PPAR-${\gamma}$) and CCAAT-enhancer-binding protein ${\alpha}$ ($C/EBP{\alpha}$). DVP also significantly suppressed lipopolysaccharide (LPS)-induced production of nitric oxide (NO), and this was accompanied by a decrease in inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) protein expression. These results demonstrate that DVP inhibits MDI-induced adipocyte differentiation of 3T3-L1 cells and LPS-induced inflammation in RAW 264.7 macrophage cells. The findings indicate that this natural product may be a good candidate as to prevent metabolic diseases.

Several growth factors and polypeptides were studied for the regeneration of periodontal supporting tissues which had been lost due to periodontal disease. But these are not commonly used for regenerators of bone tissue or alveolar bone, because of the insufficiency of studies on their side effects, genetic engineering for mass production and stability for clinical application. Recently, many natural products, which have advantage of less side effects and possibility of long-term use, have been studied for their capacity and effects of anti-bacterial, anti-inflammatory and regenerative potential or periodontal tissues. Cnidii Rhizoma, Rhinocerotis Cornu and Drynariae Rhizoma have been traditionally used as a drug for treatment of bone disease in oriental medicine. The purpose of this study was to examine the ability of alkaline phosphatase synthesis of MC3T3-E1 cells when above medicines were supplimented. MC3T3-E1 cells were cultured with ${\alpha}-MEM(negative control)$, dexamethasone(positive control), and each natural products for 3 and 5 days. And then ALP synthesis was measured by spectrophotometer for enzyme activity and by naphthol AS-BI staining for morphometry. Except Cnidii Rhizoma, all of the natural products of this study induced higher activity of ALP synthesis than controls. Among them Drynariae Rhizoma induced the highest activity. In the aspects of culturing time, all medicines did not showed the difference between 3 and 5 days, but $10^{-7}g/ml$ group of Rhinocerotis Corun showed significant increase at 3 days than at 5 days. These results indicate that several natural products have a inducing ability of ALP synthesis on osteoblasts.

Several growth factors and polypeptidesare not commonly yet used for regenerators of bone tissue or alveolar bone because of the insufficiency of studies on their side effects, genetic engineering for mass production and stability for clinical application. Recently, many natural medicines, which have advantage of less side effects and possibility of long-term use, have been studied for their capacity and effects of anti-bacterial, anti-inflammatory and regenerative potential of periodontal tissues. Olibanum, Myrrha, Phlomis Radix, and Cimicifugae Rhizoma have been traditionally used as a drug for treatment of bone disease in oriental medicine. The objective of this study was to examine the ability of alkaline phosphatase(ALP) synthesis of rat calvarial osteoblast(MC3T3-E1) when several natural medicines were supplemented. MC3T3-E1 cells were cultured with ${\alpha}$-MEM(negative control), dexamethasone(positive control), and each natural medicines for 3 and 5 days. And then ALP synthesis was measured by spectrophotometer for enzyme activity and by naphthol AS-BI staining for morphometry. All of the natural medicines induced higher activity of ALP synthesis than the negative controls. Especially Olibanumind uced the higher activity than the positive controls (p<0.05). In the aspects of culturing time, except Cimicifugae Rhizoma, the natural medicines induced higher activity of ALP synthesis at 5 days than at 3 days (p<0.05). In morphometry, all of the natural medicines showed statistical significance compared to the negative control (p<0.05). Myrrha a n d Phlomis Radix showed larger positively stained area at 5days than at 3 days, whereas the others did not showed the difference between at 5 and at 3 days(p<0.05). These results indicate that several natural medicines have an inducing ability of ALP synthesis in MC3T3-E1 cells.
Background: Periprocedural treatment with high-dose statins is known to have cardioprotective and pleiotropic effects, such as anti-thrombotic and anti-inflammatory actions. We aimed to assess the efficacy of high-dose rosuvastatin loading in patients with stable angina undergoing off-pump coronary artery bypass grafting (OPCAB). Materials and Methods: A total of 142 patients with stable angina who were scheduled to undergo surgical myocardial revascularization were randomized to receive either pre-treatment with 60-mg rosuvastatin (rosuvastatin group, n=71) or no pre-treatment (control group, n=71) before OPCAB. The primary endpoint was the 30-day incidence of major adverse cardiac events (MACEs). The secondary endpoint was the change in the degree of myocardial ischemia as evaluated with creatine kinase-myocardial band (CK-MB) and troponin T (TnT). Results: There were no significant intergroup differences in preoperative risk factors or operative strategy. MACEs within 30 days after OPCAB occurred in one patient (1.4%) in the rosuvastatin group and four patients (5.6%) in the control group, respectively (p=0.37). Preoperative CK-MB and TnT were not different between the groups. After OPCAB, the mean maximum CK-MB was significantly higher in the control group (rosuvastatin group $10.7{\pm}9.75$ ng/mL, control group $14.6{\pm}12.9$ ng/mL, p=0.04). Furthermore, the mean levels of maximum TnT were significantly higher in the control group (rosuvastatin group $0.18{\pm}0.16$ ng/mL, control group $0.39{\pm}0.70$ ng/mL, p=0.02). Conclusion: Our findings suggest that high-dose rosuvastatin loading before OPCAB surgery did not result in a significant reduction of 30-day MACEs. However, high-dose rosuvastatin reduced myocardial ischemia after OPCAB.

In the present study, we investigated the antiproliferative activity of the water extract of Samgibopae-tang (SGBPT) in NCI-H460 and A549 non-small-cell lung cancer cell lines. We found that exposure of A549 cells to SGBPT resulted in the growth inhibition in a dose-dependent manner as measured by MTT assay, however SGBPT did not affect the growth of NCI-H460 cells. The antiproliferative effect by SGBPT treatment in A549 cells was associated with morphological changes such as membrane shrinking and cell rounding up. SGBPT treatment did not induce the cell cycle arrest in both cell lines, however the frequency of sub-G1 population was concentration-dependently increased by SGBPT treatment in A549 cells. SGBPT treatment partially induced the expression of tumor suppressor p53 in A549 cells and the expression of cyclin-dependent kinase inhibitor p21(WAF1/CIP1) was markedly increased in both transcriptional and translational levels in A549 cells. The up-regulation of p21 by SGBPT occurred in a similar a concentration dependent manner to that observed with the inhibition of cell viability and induction of sub-G1 population of the cell cycle. However SGBPT treatment did not affect other growth regulation-related genes such as early growth response-1 (Egr-1), nonsteroidal anti-inflammatory drug-activated gene-1 (NAG-1), inducible nitric oxide synthease (iNOS), cyclooxygenases (COXs), telomere-regulatory factors in A549 as well as NCI-H460 cells. Taken together, these findings suggested that SGBPT-induced inhibition of human lung carcinoma A549 cell growth was aoosciated with the induction of p21 and the results provided important new insights into the possible molecular mechanisms of the anti-cancer activity of SGBPT.
Melittin is the main component of apitoxin (bee venom) that has been reported to have anti-inflammatory and anti-cancer effects. Herein, we demonstrated that inhibition of epithelial-mesenchymal transition (EMT) by melittin causes suppression of cancer cell migration and invasion. Melittin significantly suppressed the epidermal growth factor (EGF)-induced cell migration and invasion in lung cancer cells. Moreover, melittin up-regulated the expression of epithelial marker protein, E-cadherin, and down-regulated the expression of EMT related proteins, vimentin and fibronectin. Mechanistic studies revealed that melittin markedly suppressed the expression of EMT mediated transcription factors, ZEB2, Slug, and Snail. The EGF-induced phosphorylation of AKT, mTOR, P70S6K, and 4EBP1 was also inhibited by melittin, but not that of ERK and JNK. Therefore, the inhibitory effect of melittin on migration and invasion of lung cancer cells may be associated with the inhibition of EMT via blocking of the AKT-mTOR-P70S6K-4EBP1 pathway.
Arterial thrombosis and its associated diseases are considered to constitute a major healthcare problem. Arterial thrombosis, defined as blood clot formation in an artery that interrupts blood circulation, is associated with many cardiovascular diseases. Oxidative stress is one of many important factors that aggravates the pathophysiological process of arterial thrombosis. Apurinic/apyrimidinic endonuclease 1/redox factor-1 (Ref-1) has a multifunctional role in cells that includes the regulation of oxidative stress and anti-inflammatory function. The aim of this study was to investigate the therapeutic effect of adenovirus-mediated Ref-1 overexpression on arterial thrombosis induced by 60% FeCl3 solution in rats. Blood flow was measured to detect the time to occlusion, thrombus formation was detected by hematoxylin and eosin staining, reactive oxygen species (ROS) levels were detected by high-performance liquid chromatography, and the expression of tissue factor and other proteins was detected by Western blot. FeCl3 aggravated thrombus formation in carotid arteries and reduced the time to artery occlusion. Ref-1 significantly delayed arterial obstruction via the inhibition of thrombus formation, especially by downregulating tissue factor expression through the Akt-GSK3β-NF-κB signaling pathway. Ref1 also reduced the expression of vascular inflammation markers ICAM-1 and VCAM-1, and reduced the level of ROS that contributed to thrombus formation. The results showed that adenovirus-mediated Ref-1 overexpression reduced thrombus formation in the rat carotid artery. In summary, Ref-1 overexpression had anti-thrombotic effects in a carotid artery thrombosis model and could be a target for the treatment of arterial thrombosis.
