Wheat is rich in sources of fiber, oligosaccharides, and resistant starch, simple carbohydrates which may have a protective role against carcinoma. Additionally, Whole wheat/bran as well includes contains phytochemicals such as flavonoids, lignans, folate, phytosterols, phenolic acids, and tocols. The above phytochemicals suitable forms antioxidant and cholesterol-reducing activities. Phytoestrogens are regarded as especially essential in the preventative measures of hormonally dependent malignancies such as breast cancer (BC). In this study lowered BC risk has been associated with whole grain/bran consumption with an odds ratio (OR=0.24 and 95 %CI=0.10-0.56). Wheat/bran appears to have a reliable protective impact against BC. While intake of white bread has been associated with a high risk of BC (OR=2.63 and CI 95 %=1.07-6.48). Also, the E-Selectin (SELE) Single nucleotide polymorphisms (SNPs) rs5353 A/G and rs932307 C/T were investigated using the sanger sequences approach. There was a positive association between genotypes (rs5353 GG+AG) and (rs932307 TT+CT) with rate consumption of wheat-white/bread and these genotypes were more frequent in patients had BC in comparison with a significant difference (P=0.03) (P=0.01), respectively. The genotypes (GG+AG) frequency of the rs5353 polymorphism and (TT+CT) genotypes of the rs932307 polymorphism in the present study had a high risk of cancer with (OR=3.05), (OR=4.17) respectively. While these genotypes showed no significant association with the rate of whole grain consumption in patients and control. Therefore, the type of wheat may associate with increased incidence of disease-related with type of Polymorphism because some present genotypes of SNPs showed high (OR) which may refer to their positive associated with disease, the white wheat consumption may active the risky association between SNPs and BC.

The GroEL heat-shock protein from Fusobacterium nucleatum, a periodontopathogen, activates risk factors for atherosclerosis in human microvascular endothelial cells (HMEC-1) and ApoE-/- mice. In this study, we analyzed the signaling pathways by which F. nucleatum GroEL induces the proinflammatory factors in HMEC-1 cells known to be risk factors associated with the development of atherosclerosis and identified the cellular receptor used by GroEL. The MAPK and NF-${\kappa}B$ signaling pathways were found to be activated by GroEL to induce the expression of interleukin-8 (IL-8), monocyte chemoattractant protein 1 (MCP-1), intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), E-selectin, and tissue factor (TF). These effects were inhibited by a TLR4 knockdown. Our results thus indicate that TLR4 is a key receptor that mediates the interaction of F. nucleatum GroEL with HMEC-1 cells and subsequently induces an inflammatory response via the MAPK and NF-${\kappa}B$ pathways.

Vascular inflammation is an important event in the development of vascular diseases such as tumor progression and atherosclerosis. This study was to investigate the inhibitory effects of WK-38, a new herbal prescription for the treatment of atherosclerosis, on vascular inflammation in human umbilical vein endothelial cells (HUVEC). WK-38 is composed of Rhei Rhizoma, Magonoliae Cortex, Moutan Cortez Radicis. Pretreatment with WK-38 was significantly blocked TNF-$\alpha$-induced expression level of cell adhesion molecules such as vascular cell adhesion molecule-1 (VCAM-1), intracellular adhesion molecule-1 (ICAM-1), and endothelial cell selectin (E-selectin) in a dose-dependent manner. TNF-$\alpha$-induced cell adhesion in co-cultured U937 and HUVEC was also blocked by pretreatment with WK-38. Moreover, WK-38 significantly suppressed p65 NF-${\kappa}B$ translocation into the nucleus by TNF-$\alpha$ as well as the phosphorylation and degradation of $I{\kappa}B-{\alpha}$. In conclusion, the present data suggested that WK-38 could suppress TNF-$\alpha$-induced vascular inflammatory process, though inhibition of NF-${\kappa}B$ activation in HUVEC.

BACKGROUND/OBJECTIVES: Curcuma zedoaria R. (Zingiberaceae) has been used to treat headache, fever, and hypertension-related symptoms in Asian countries, including Korea, China, and Japan. We investigated whether dietary intake of a C. zedoaria extract (CzE) affected atherosclerosis in vivo. MATERIALS/METHODS: Apolipoprotein E-deficient (ApoE^-/-) mice (n = 32) were fed a normal diet (ND), a high-cholesterol diet (HCD), an HCD containing CzE (100 mg/kg/day), or an HCD containing simvastatin (10 mg/kg/day) for 12 weeks. The anti-atherosclerotic effects were evaluated by observing changes in fatty streak lesions, immunohistochemical analysis, ex vivo fluorescence imaging, lipid profiles, and western blot analysis. RESULTS: The CzE-fed group showed a 41.6% reduction of atherosclerosis. Furthermore, CzE significantly reduced the levels of serum triglyceride, high-density lipoprotein, the chemokine (C-X3-C-motif ) ligand 1, the adhesion molecules vascular cell adhesion molecule-1, intracellular adhesion molecule-1, and E-selectin; down-regulation of tumor necrosis factor-α, interleukin-6, high mobility group box-1, and cathepsin levels in the aortic sinuses and aortas of ApoE^-/- mice were also observed. CONCLUSIONS: The results suggest that the inclusion of a water extract of C. zedoaria in a HCD is closely correlated with reducing the risk of vascular inflammatory diseases in an ApoE mouse model.

This study was conducted to investigate antioxidant activity and anti-immunological inflammatory effect of Allium victorialis subsp. platyphyllum extracts (AVPEs). Antioxidant activities of AVPEs were determined by free radical scavenging assay and reducing power test. Leaf-part extract had comparatively better antioxidant activity than other-part extracts. Antioxidant activity of extracts had protective effect for human umbilical vein endothelial cells (HUVECs) against superoxide anions secreted from activated neutrophils. Also, we observed AVPEs had inhibitory effects on the adherence of monocytic THP-1 to HUVEC monolayer to the basal level. Inhibitory effect on cell adhesion was caused by suppression of tumor necrosis factor-${\alpha}\;(TNF-{\alpha})-upregulated$ expression of vascular cellular adhesion molecule-1 (VCAM-1) and E-selectin in HUVECs. From these results, we expect to support the evidence of anti-immunological inflammatory effects of Allium victorialis subsp. platyphyllum (AVP) as a Korean traditional pharmaceutical.

The Camella japonica flower(CJF) extract was studied for their anti-angiogenenic and anti-cell adhesion effect. CJF-extract inhibited the tube formation on human umbilical vein endotherial cells(HUVEC) with butanol extract by 70.2%, acetone extract by 54.2%, ethyl acetate extract by 37.0%, chloroform extract by 21.2%. Cell adhesion molecules were effectively suppressed at different concentration of CJF at 50, 100, 200 ug/well such as for intercellular adhesion molecule(ICAM) by 5.9%, 29.4% and 52.9%, for vascular cell adhesion molecule(VCAM) by 12.5%, 43.8% and 62.5%, for E-selectin by 7.1%, 21.4% and 35.7%, respectively. Signal molecules of vascular endotherial growth factor receptor 2(VEGFR2), ${/beta}$-catenin and PI3K are inhibited by different concentration of CJF at 10, 20 and 30 ${\mu}g/mL$ with western blot. Angiogenesis will be inhibited with suppressing NF-kB molecule resulted in signal molecules blocked by CJF. CJF will be useful materials for treatment of angiogenesis related diseases such as cancer, metastasis, rheumathioid arthritis and obesity.

Anti-angiogenesis and anti-cell adhesion effects were investigated with different dose of Camellia japonica leaf (CJL) extract for applying anti-cancer, anti-metastasis and anti-obesity. Cytotoxicity on HUVECs was very low at 200 ug/mL of CJL-extract. Anti-angiogenic ratio at increasing dose of 1.5 ug/mL, 3.0 ug/mL, 15 ug/mL and 30 ug/mL was showed 30.7%, 38.5%, 53.8%, and 70.0%, respectively. Also, anti-cell adhesion effect at concentration of $50{\mu}g{/well},\;100{\mu}g{/well}\;and\;200{\mu}g{/well}$ was expressed on E-selectin by 46.7%, 66.7%, and 86.76%, on VCAM-1, 23.0%, 61.5%, and 84.6%, and on ICAM-1, 11%, 55.5%, and 88.8%, respectively. For inquiring anti-angiogenesis mechanism, when western blot was performed with different dose of CJL extract, signal molecules of VEGFR-2, $\beta$-catenin and PI3-K were suppressed. As the signal transduction from VEGFR-2, $\beta$-catenin and PI3-K to NF-${\kappa}$B was interupted, angiogenesis could not be occurred causing not activated NF-kB. C. japonica leaf (CJL) is a useful herb for developing therapeutics of angiogenesis related diseases such as cancer, metastasis, rheumathioid arthritis and obesity.

Staphylococcus aureus is a major human pathogen that is associated with various types of local and systemic infection. Staphylococcal protin A (SPA), a highly expressed surface component of S. aureus, may have a role in virulence such as activating inflammation and interfering with immune clearance. We examined the effect of recombinant SPA on inflammatory response in human HaCaT keratinocytes. The recombinant SPA protein was prepared using the pET-28a Vector System in Escherichia coli. The expression of pro-inflammatory related adhesion molecules and cytokines in HaCaT cells incubated for 6, 12, and 24 h with SPA (2 ${\mu}g$/ml) was analyzed by comparative RT-PCR or ELISA. The expression of E-selectin, ICAM-1, MCP-1, IL-6 and IL-8 was significantly increased in HaCaT from 6 to 24 h after treatment with SPA. SPA showed the effect on the adhesion-promoting ability of U937 monocytes to HaCaT cells. Our data demonstrate that SPA stimulates inflammatory response of HaCaT cells, implicating an important factor for exacerbation of skin inflammation of immunologic disease.

Excessive salt intake induces hypertension, but several gamma-aminobutyric acid (GABA) supplements have been shown to reduce blood pressure. GABA-salt, a fermented salt by L. brevis BJ20 containing GABA was prepared through the post-fermentation with refined salt and the fermented GABA extract. We evaluated the effect of GABA-salt on hypertension in a high salt, high cholesterol diet induced mouse model. We analyzed type 1 macrophage (M1) polarization, the expression of M1 related cytokines, GABA receptor expression, endothelial cell (EC) dysfunction, vascular smooth muscle cell (VSMC) proliferation, and medial thicknesses in mice model. GABA-salt attenuated diet-induced blood pressure increases, M1 polarization, and TNF-α and inducible nitric oxide synthase (NOS) levels in mouse aortas, and in salt treated macrophages in vitro. Furthermore, GABA-salt induced higher GABAB receptor and endothelial NOS (eNOS) and eNOS phosphorylation levels than those observed in salt treated ECs. In addition, GABA-salt attenuated EC dysfunction by decreasing the levels of adhesion molecules (E-selectin, Intercellular Adhesion Molecule-1 [ICAM-1], vascular cell adhesion molecule-1 [VCAM-1]) and of von Willebrand Factor and reduced EC death. GABA-salt also reduced diet-induced reductions in the levels of eNOS, phosphorylated eNOS, VSMC proliferation and medial thickening in mouse aortic tissues, and attenuated Endothelin-1 levels in salt treated VSMCs. In summary, GABA-salt reduced high salt, high cholesterol diet induced hypertension in our mouse model by reducing M1 polarization, EC dysfunction, and VSMC proliferation.
