  • To identify new active anti-wrinkle ingredients, this study investigated the anti-wrinkle effects of Schizandra chinensis Baillon fermented with Lactobacillus plantarum (SCF) by assessment of cytotoxicity of human dermal fibroblast, collagen biosynthesis, matrix metalloproteinase-I (MMP-1) inhibition and elastase inhibition. S. chinensis was fermented with L. rhamnosus for 1 day at $37^{\circ}C$. The cytotoxicity of SCF was evaluated by a cytopathic effect reduction method. Effects on collagen biosynthesis and matrix metalloproteinase-I (MMP-1) of SCF were evaluated by previous reported method using procollagen type-IC peptide EIA kit and Matrix Metalloproteinase-1 Biotrack activity Assay Kit, respectively. Elastase inhibition assay was conducted by reaction of enzyme and substrate using N-Suc-$(Ala)_3$-nitroanilide as the substrate. As the results, SCF didn't show cytotoxicity against human dermal fibroblast at concentration of $100{\mu}g/mL$. Also, SCF was increased collagen synthesis and showed inhibitory effect of MMP-1 (p < 0.05). In the elastase inhibition assay, the $IC_{50}$ of SCF was $36.4{\mu}g/mL$. Therefore, our results indicated that SCF possesses anti-wrinkle effects and can be used practically for anti-wrinkle care of skin.

  • Skin wrinkle formations are associated with collagen synthesis and matrix metalloproteinase-I(MMP-1) activity. This study was carried out to find out skin wrinkle reducing components in Torilis Fructus. Torilis Fructus were extracted with 70% ethanol and the ethanol extracts were systematically fractionated with n-hexane, ethylacetate, n-butanol and distilled water. Among them, antiwrinkle component from n-hexane fraction was purified by several column chromatographies and HPLC, which identified as torilin by $^1H-NMR,\;^{13}C-NMR$ and ESI-MS. To determine cell viability, collagen biosynthesis and MMP-1 activity, human dermal fibroblast was treated with 1-5 ppm concentrations of Torilis Fructus extract fraction and torilin. Cell viability was showed 84-102% at all group treated with 1-5 ppm. Collagen synthesis was increased in all group, especially torilin-treated group was highest amount. Active forms of MMP-1 were decreased in all group. From these results, we consider that Torilis Fructus have several antiwrinkle components and torilin may be one of the effective components.

  • The present work was undertaken to evaluate the antimetastatic potential of capsaicin (8­methyl-N-vanillyl-6-nonenamide) by measuring its effects on matrix metalloproteinase activity, cell invasion and lung metastasis. Significant inhibition of matrix metalloproteinase-2 activity by capsaicin (100 $\mu$M) was detected by gelatin zymography. In vitro invasion assay showed capsaicin (50, 100 $\mu$M) reduced tumor cell invasion ($28-40\%$). Capsaicin (i.p., 2.5 mg/kg) inhibited development of lung colonization ($58\%$). These results suggest that capsaicin prevents metastasis in part through suppression of invasion of B16F10 melanoma cells by inhibiting matrix metalloproteinase-2 responsible for degradation of extracellular matrix.

  • Tissue plasminogen activator (tPA) is used to lyse clots and reperfuse brain in ischemic stroke. However, sideeffects of intracerebral hemorrhage (ICH) and edema limit their clinical application. In part, these phenomena has been linked with elevations in matrix metalloproteinase-9 (MMP-9) in neurovascular unit. However little is known about their regulatory signaling pathways in brain cells. Here, I examine the role of MAP kinase pathways in tPA-induced MMP-9 regulation in rat cortical astrocytes. tPA $(1-10\;{\mu}g/ml)$ induced dose-dependent elevations in MMP-9 and MMP-2 in conditioned media. Although tPA increased phosphorylation in two MAP kinases (ERK, JNK), only inhibition of the JNK pathway by the JNK inhibitor SP600126 significantly reduced MMP-9 upregulation. Neither ERK inhibition with U0126 nor p38 inhibition with SB203580 had any significant effects. Taken together, these results suggest that c-jun N-terminal kinase (JNK) plays an essential role for tPA-induced MMP-9 upregulation.

  • Diallyl disulfide (DADS), an oil-soluble organosulfur compound in garlic has been reported to suppress tumor growth and to induce apoptosis in cancer. In the present study, we investigated the effects of DADS on pulmonary metastasis of B16-F10 murine melanoma cells. DADS (i.p. 40 mg/kg) significantly (p<0.05) reduced the number of pulmonary metastatic nodules (48%) in experimental pulmonary metastasis assay. We also found that DADS inhibited adhesion, invasion and migration of B16-F10 melanoma cells in a dose-dependent manner. To study the antimetastatic potential of DADS, we performed the effects of DADS on matrix metalloproteinase activity. DADS significantly inhibited the expression of matrix metalloproteinase-2 activity in B16-F10 cells by gelatin zymography. These results suggest that DADS prevent metastasis in part through suppression of migration of B16-F10 melanoma cells by Inhibiting matrix metalloproteirase-2 responsible for degradation of extracellar matrix.

  • Abalone, a marine organism inhabiting the west coast of Korea, has antioxidant and anti-inflammatory effects, and is a resource with potential to be used in various industries such as antibiotic development and cosmetic raw materials. In this study, we chose abalone among various marine lives on the west coast. Antibacterial peptide (AMP) was separated from abalone and its derivative Ab4-7 was identified and its physiological activity was studied. The treatment of Ab4-7 in inflammatory RAW 264.7 to check the anti-inflammatory efficacy nhibited inflammatory cytokines, TLR4, TNF-α, IL-1β, COX-2, and iNOS and increased mRNA manifestation of HO-1, genes related to antioxidants. Based on the strong antioxidant and anti-inflammatory effects of Ab4-7, the effects of Ab4-7 in the inflammatory RAW 264.7 cells were identified through RT-PCR, which regulates the gene Matrix Metalloproteinase (MMPs) that induces a variety of inflammatory skin diseases by engaging in the decomposition of the extrocellular matrix metalloproteinase (ECM). Taken together, it is concluded that Ab4-7 has a powerful anti-inflammatory and antioxidant effect and can be used as a functional material for various inflammatory skin disease treatments by controlling the genes associated with matrix metalloproteinase (MMPs).

  • Matrix metalloproteinases (MMPs) can degrade a wide range of extracellular matrix components. It has been reported that MMP-9 are activated after focal ischemia in experimental animals. (-)-Epigallocatechin-3-gallate (EGCG), a major constituent of green tea polyphenols, is a potent free radical scavenger and reduces the neuronal damage caused by oxygen free radicals. And it has been known that EGCG could reduce the infarction volume in focal brain ischemia and inhibit MMP-9 activity. To delineate the relationship between the anti-ischemic action and the MMP-9-inhibiting action of EGCG, we investigated the effect of EGCG on brain infarction and the activity of matrix metalloproteinase-9 induced by permanent middle cerebral artery occlusion (pMCAO) in ICR mice. EGCG (40 mg/kg, i.p. $15{\sim}30min$ prior to MCAO) significantly decreased infarction volume at 24 hr after MCAO. GM 6001 (50 mg/kg, i.p. $15{\sim}30min$ prior to MCAO), a MMP inhibitor, also significantly reduced infarction volume. In zymogram, MMP-9 activities began to increase at ipsilateral cortex at 2 hr after MCAO, and the increments of MMP-9 activities were attenuated by EGCG treatment. Western blot for MMP-9 also showed patterns similar to that of zymogram. These findings demonstrate that the anti-ischemic action of EGCG ire mouse focal cerebral ischemia involves its inhibitory effect on MMP-9.

  • Background: CpG DNA plays an important role in immune cell function. This study examined whether the temporal control of toll-like receptor (TLR)9 by CpG DNA can regulate the expression of matrix metalloproteinase-9(MMP-9). Methods and materials: Macrophages were cultured in the presence of 10% FBS. For the various MMP genes analysis, RT-PCR and real-time PCR were performed. In addition, zymography assay performed for the MMP activity. The phosphorylation assay did for the ERK1/2 and NF${\kappa}B$ activation, and luciferase promoter assay was for the NF${\kappa}B$ activity. Results: CpG DNA induced the mRNA expression of MMP-2, MMP-9, and MMP-13, but not of MMP-7, MMP-8, and MMP-12, in a time-dependent manner. Especially, the mRNA expression of MMP-9 was strongly induced by CpG DNA using real-time RT-PCR. The TLR9 inhibitor, chloroquine, suppressed CpG DNA-induced MMP-9 expression and its activity. Moreover, CpG DNA induced the phosphorylation of ERK and the inhibition of ERK by U0126 suppressed CpG DNA-induced MMP-9 expression and its activity. CpG DNA stimulated $I{\kappa}B-{\alpha}$ degradation and luciferase activity. In addition, pretreatment of SN-50, the inhibitor of NF${\kappa}B$, strongly blocked the CpG DNA-induced MMP-9 expression and activity. Conclusion: These observations suggest that CpG DNA may play important roles in the activation of macrophages by regulating the production of MMP-9 via the sequential TLR9-ERK-NF${\kappa}B$ signaling pathway.

  • Portulaca oleracea L. is an edible plant widely consumed in daily diet throughout Europe, Asia and America. In this study, protective effects of P. oleracea L. extracts against oxidative stress and matrix metalloproteinase (MMP) activity induced by ultraviolet B (UVB) radiation were investigated using HaCaT immortal human keratinocytes. In this context, the mRNA and protein productions of MMPs (MMP-1, -2, and -9) and type I procollagen, which are major markers of photoaging induced by UVB radiation in HaCaT keratinocytes, were evaluated. Furthermore, UVB-induced reactive oxygen species (ROS) generation and mRNA and protein expression levels of superoxide dismutase-1 (SOD-1), oxygenase-1 (OH-1), and nuclear factor-erythroid 2-related factor-2 (Nrf-2), all of which are associated with the antioxidant balance, were investigated. As shown by the results, UVB radiation induced ROS formation and led to increased production of MMPs and decreased collagen production in human keratinocytes, which resulted in skin photoaging or photodamage. The treatment with P. oleracea L. extracts downregulated MMP (MMP-1, -2, and -9) production and upregulated type I procollagen expression in UVB-induced HaCaT cells. Furthermore, treatment with the extracts decreased UVB-induced ROS generation and increased the expression of antioxidant enzymes, such as SOD-1 and OH-1, through the Nrf-2 pathway. Taken together, these results suggest that P. oleracea L. extracts could be a potential cosmeceutical agent for the prevention of skin photoaging or photodamage.
