        Background: Astilbe chinensis (Maxim.) Franch. Et Savat. is a plant belonging to Saxifragaceae family and contains various active ingredients including astilbin and bergenin. It has been used as a traditional Korean medicine to improve fever, pain, and cough. Recently, a number of Korean medical resources have been studied for cancer and inflammation treatment, but A. chinensis (Maxim.) Franch. Et Savat. has not yet been investigated. Consequently, this study investigated the inhibitory effect of ethanol extracts from A. chinensis (Maxim.) Franch. Et Savat. (ARE) on oxidative stress and colorectal cancer using RAW264.7 and the human colorectal cancer cell line HCT-116. Methods and Results: In total, 500 ㎍/㎖ ARE reduced cell viability by 38.96 ± 1.32%, and increased caspase-3 activity by 133.08 ± 3.41% in HCT-116 cells. Moreover, TUNEL signaling and the early apoptosis ratio (34.56 ± 1.67%) increased by 500 ㎍/㎖ ARE treatment. H2O2-induced oxidative stress and cell death were diminished by 500 ㎍/㎖ ARE treatment through decreasing ROS (reactive oxygen species). Conclusions: The inhibitory effects of ARE against human colorectal cancer cells is mediated by apoptosis and caspase-3 activation, and H2O2-induced ROS generation and cell death are decreased by ARE treatment in RAW264.7 cells. However, further study is required to explore how ARE treatment is involved in the signaling pathway to decrease ROS.

        In this study, we elucidated anti-cancer activity and potential molecular mechanism of 70% ethanol extracts from Taxilli Ramulus (Taxillus chinensis (DC.) Danser) (TR-E70) against human colorectal cancer cells. Anti-cell proliferative effect of TR-E70 was evaluated by MTT assay. The effect of TR-E70 on the expression of cyclin D1 in the protein and mRNA level was evaluated by Western blot and RT-PCR, respectively. TR-E70 suppressed the proliferation of human colorectal cancer cell lines, HCT116 and SW480. Although TR-E70 decreased cyclin D1 expression in protein and mRNA level, decreased level of cyclin D1 protein by TR-E70 more dramatically occurred than that of cyclin D1 mRNA. Cyclin D1 downregulation by TR-E70 was attenuated in presence of MG132. In addition, TR-E70 phosphorylated threonine-286 (T286) of cyclin D1. TR-E70-mediated cyclin D1 degradation was blocked in presence of LiCl as an inhibitor GSK3β but not PD98059 as an ERK1/2 inhibitor and SB203580 as a p38 inhibitor. Our results suggest that TR-E70 may downregulate cyclin D1 as one of the potential anti-cancer targets through GSK3β-dependent cyclin D1 degradation. From these findings, TR-E70 has potential to be a candidate for the development of chemoprevention or therapeutic agents for human colorectal cancer.

        Background: In this study, examined the effects of an extract of a mixture of Angelica gigas, Cnidium officinale, Paeonia lactiflora, and Rehmannia glutinosa fermented by Leuconostoc mesenteroides, with enhanced value and functionality. In oriental medicine, a mixture of these herbs is called Samultang. Methods and Results: In this study, we evaluated the effects of a fermented extract of Samultang on oxidative stress, procollagen type I expression, and melanin production. Samultang was extracted with 70% ethanol, followed by inoculation with Leuconostoc mesenteroides to obtain the fermented extract. The evaluation of viability of B16F10 cells and human foreskin fibroblast (HHF) revealed that both ethanol and fermented extracts of Samultang were non-toxic. The results of 1,1-diphenyl-2-picrylhydrazyl (DPPH) test showed that the fermented extract of Samultang (SC50 value = 100 ㎍/㎖) was a more effective DPPH free radical scavenger than its ethanol extract. In addition, procollagen type I expression was higher in cells treated with the fermented extract of Samultang than in cells treated with ethanol. In the non-toxic concentration range, the fermented extract of Samultang showed strong inhibitory effect on melanin production in α-melanocyte stimulatin hormone-stimulated B16F10 cells (IC50 = 37.9 ㎍/㎖). Conclusions: These results suggest that the fermented extract of Samultang has considerable protential as a cosmetic ingredient owing to its antioxidant, anti-wrinkle, and whitening effects.

        Background: This study was performed to evaluate the protective effect of Saururus chinensis ethanol extract (SCE) against styrene toxicity in mouse spermatocyte cells [GC-2spd (ts) cell line]. Methods and Results: Cytotoxicity in mouse spermatocyte cells was measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Generation of reactive oxygen species (ROS) was determined using 2’,7’-dichlorodihydrofluorescein diacetate (DCF-DA) assay. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and western blotting were performed to quantify the mRNA and protein expression levels, resepectiviely, of stress or apoptosis-related genes including p21, p53, heat shock protein 70 (Hsp70), heat shock protein 90 (Hsp90), Bax, Bcl-2, and caspase-3. The results of the MTT assay showed that 50 ㎍/㎖ SCE did not affect cell viability. ROS generation in mouse spermatocyte cells increased by treatment with 100 μM styrene, and decreased by co-treatment with SCE. SCE repressed the mRNA expression of stress-related genes, which increased by styrene treatment. In addition, SCE inhibited the apoptosis of mouse spermatocyte cells by ameliorating mRNA and protein levels of apoptotic genes that were altered by styrene treatment. Conclusions: These results suggest that SCE may alleviate styrene toxicity in mouse spermatocyte cells by reducing ROS stress and regulating genes related to styrene toxicity.
