UV irradiation leads to distinct changes in skin connective tissue, which is degradation of collagen. Many of these alterations in the extracellular matrix are mediated by matrix metalloproteinases. In this study, to develop a new anti-aging agent, we screened the antioxidant activity of solvent fractions from ethanolic extract of Melothria Heterophylla. Among the four solvent fractions tested, the EtOAc fraction exhibited the highest antioxidant activity. It was investigated the inhibitory effect of the EtOAc fraction on the expression and activity of MMP-1 in UVA-irradiated human dermal fibroblasts. The EtOAc fraction inhibited the activity of MMP-1 in a dose dependent manner with the $IC_{50}$ values of $9{\mu}g/mL$. Also, UVA-induced MMP-1 expression was reduced about $90\%$ by $100{\mu}g/mL$ of the EtOAc fraction but MMP-1 mRNA expression was not inhibited. Therefore, we conclude that the EtOAc fraction significantly inhibits MMP-1 expression at the protein level. From these results, we suggest that the EtOAc fraction from M. heterophylla could be used as a new anti-aging agent for the photo-damaged skin.

Adriamycin is a major cancer chemotherapeutic agent against a me range of human neoplasms. However, its clinical application is limited since It has a variety of side effects, bone marrow suppression and cardiotoxity, and this toxicity appears by free radical. This study investigated the effect of Ampelopsis radix on the toxicity of adriamycin. The methanol fraction reduced slightly adriamycin induced lipid peroxidation and superoxide production at the dose of 50mg /kg. 1.p., respectively. During the adriamycin administration. Protein bound-SH, nonprotein bound-SH, and glutathione-5-transferase did not change, but methanol fraction treated group were markedly increase. These results indicated that Ampelopsis radix has a major influence on the thiol group and related enzyme activity on the antioxidative effects.

Although many studies have been performed to elucidate the molecular consequence of ultraviolet irradiation on an aging, little is known about the effect of natural products. Matrix metalloproteinases (MMPs) we known to play an important role in (a) photoaging. Hete we investigated the effect of $1,2,4,6-tetra-O-galloyl-{\beta}-{_D}-gluco- pyranose (1)$ and 3,4,5-trihydroxybenzoic acid (2) on the expression of MMP-1 in UVA-irradiated human skin fibroblasts (products), (on the) activity of MMP-1, and (on the) scavenging activities of free radicals. Compounds 1 and 2 were isolated from Melothria heterophylla (Cucurbitaceae). These compounds were found to scavenge free radicals and reactive oxygen species (ROS) and were measured to have the $SC_{50}$ values of $3.9{\mu}M\;and\;13.3{\mu}M$ against the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and $4.3{\mu}M\;and\; 4.0{\mu}M$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. Compounds 1 and 2 showed a dose-dependent inhibitory effect on the e):pression and activity of MMP-1 in the UVA-irradiated human skin fibroblasts. Therefore, we concluded that compounds 1 and 2 significantly inhibited MMP-1 expression at the protein level. Also, these compounds were determined to have a potent antioxidant activity. From these results, we suggest that these compounds nay be used as (a) new anti-aging agents for the photo-damaged skin.

Objective : The aim of this study is to evaluate anti-cancer effects of $Ampelopsisradix$ Extract (AE) on human lung cancer A549 cells. Method : The apoptotic activities and cell growth arrest activities of AE were measured using 3-[4,5-dimethyl-thiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. The molecules involved in apoptotic process were assessed by western blotting. Result : Treatment of AE potently reduced cell viability in a dose-dependent manner in A549 cells. AE (100-500 ${\mu}g/m{\ell}$) resulted in apoptosis via activation of caspase 9 following PARP cleavage in a time-and dose-dependent manner. The levels of Bax and Bad levels were increased by AE with a concomitant decrease of Bcl-xL. In addition, AE at the low dose (30 ${\mu}g/m{\ell}$) significantly inhibited cell growth in the presence of serum. Conclusion : AE has the potential as a therapeutic agent against lung cancer.

Matrix metalloproteinases (MMPs) are known to play an important role in photoaging by mediating the degradation of extracellular matrix proteins. In this study, to develop a n ew anti-aging agent, we investigated the antioxidant activity and the inhibitory effect of Melothria heterophylla extract on expression of MMP-1 in UVA-irradiated human dermal fibroblasts and MMP-1 activity. The M.heterophylla extract was found to scavenge radicals and reactive oxygen species (ROS) with the $SC_{50}$ values of $13{\mu}g/ml$ against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and $20{\mu}g/ml$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. UVA-induced MMP-1 expression was reduced about 80% by $100{\mu}g/ml$ of the M.heterophylla extract but MMP-1 Mrna expression was not inhibited. Therefore, we conclude that the M.heterophylla extract significantly inhibits MMP-1 expression at the protein level. Also, the M.heterophylla extract inhibited MMP-1 activity in a dose dependent manner. From these results, we suggest that the M.heterophylla extract can be used as a new anti-aging agent by antioxidant activity, regulation of UVA-induced MMP-1 production, and inhibition of MMP-1 activity.

Objectives: In this study, we investigated the inhibitory effects of Ampelopsis Radix methanol(AR-M) extract on allergic inflammation in activated human mast cells and its potential therapeutic or toxic effects. Methods: Ampelopsis Radix(AR) was extracted with 80% methanol. HMC-1 cells, a human mast cell line, were treated with different concentrations of AR-M extract, and then stimulated with PMA plus A23187. The cell toxicity of AR-M extract was determined by MTT assay. The concentrations of $PGE_2$ and cytokines were measured by ELISA. The gene expression of COX-2 and its protein levels were determined by RT-PCR and Western blot. The phosphorylation of ERK MAPK and the NF-${\kappa}B$ activation were determined by Western blot. Results: AR-M extract was significantly inhibited the production of PGE2 and inflammatory cytokines(TNF-${\alpha}$, IL-6 and IL-8) in PMA/A23187-stimulated HMC-1 cells. AR-M extract also attenuated the mRNA expression of COX-2 and its protein induction. Furthermore, AR-M extract attenuated PMA/A23187-induced phophorylation of ERK1/2 MAPK and the NF-${\kappa}B$ p65 subunit translocation into nuclear of HMC-1 cells. AR-M extract significantly decreased PMN A23187-induced release of histamine in a dose-dependent manner. Conclusions: These results indicate that Ampelopsis Radix shows the property of anti-allergic inflammation In vitro through suppressing the production of inflammatory mediators released from mast cells, suggesting have a potential for the treatment of allergic diseases.

Objectives : Osteoporosis is a systemic skeletal disorder characterized by reduced bone mineral density and increased risk of fractures. Bisphosphonates and selective estrogen receptors, which are bone resorption inhibitors that are currently widely used as osteoporosis treatments, show serious side effects when administered for a long time. Research on bone resorption inhibitors that complement the problems of existing treatments is needed. The purpose of this study was to investigate the effect of inhibiting osteoclast differentiation and activity on the tuberous root of Ampelopsis japonica (Thunb.) Makino (AM). Methods : After extracting AM using distilled water and ethanol, the inhibitory effects of the two solvents on osteoclast differentiation were compared using the RANKL-induced in vitro experimental model and the TRAP assay kit. The impact of AM on bone resorption was investigated through the pit formation assay, and its effect on F-actin formation was assessed through fluorescent staining. Additionally, protein and mRNA expression levels of osteoclast differentiation markers (NFATc1, c-Fos, TRAP and ATP6v0d2) and resorption markers (MMP-9, CTK, and CA2) were analyzed via western blot and RT-PCR. Results : AM treatment significantly decreased the number of TRAP-positive cells and pit formation area. Furthermore, AM suppressed both the protein and mRNA expression of NFATc1 and c-Fos, key transcription factors involved in osteoclast differentiation and it downregulated the expression of osteoclast-associated genes such as TRAP, CTK, MMP-9, CA2, and ATP6v0d2. Conclusions : These results suggest that AM can inhibit bone resorption and osteoclast differentiation, indicating its potential for use in the treatment and prevention of osteoporosis.
