Pathological increases in adipogenic potential with decreases in osteogenic differentiation occur in osteoporotic bone marrow cells. Previous studies have shown that bioactive materials isolated from natural products can reciprocally regulate adipogenic and osteogenic fates of bone marrow cells. In this study, we showed that Eupatorium japonicum stem extracts (EJE) suppressed lipid accumulation and inhibited the expression of adipocyte markers in multipotent C3H10T1/2 and primary bone marrow cells. Conversely, EJE stimulated alkaline phosphatase activity and induced the expression of osteoblast markers in C3H10T1/2 and primary bone marrow cells. Daily oral administration of 50mg/kg of EJE for 6 weeks to ovariectomized rats prevented body weight increase and bone mineral density decrease. Finally, activity-guided fractionation led to the identification of coumaric acid and coumaric acid methyl ester as bioactive anti-adipogenic and pro-osteogenic components in EJE. Taken together, our data indicate a promising possibility of E. japonicum as a functional food and as a therapeutic intervention for preventing osteoporosis and bone fractures. © 2014 Mary Ann Liebert, Inc.

This study was conducted to examine the effect of egg shell membrane hydrolysates (ESMH) on wrinkle, UV, and moisture protection for cosmetic use. ESMH were fragmented as whole ESMH (before fractioning), Fraction I (> 10 kDa), Fraction II (3-10 kDa), and Fraction III (< 3 kDa). In order to test whether fractionated ESMH can be used for functional cosmetic materials, we examined not only the level of hyaluronic acid and collagen production, but also the MMP-1 activity using a HaCaT and CCD-986Sk cell line. Our study treated each sample of fractionated ESMH with different concentrations (0.01, 0.1, 1 mg/mL). In our in vivo research, we used hairless mice that had been exposed to UV-B to induce wrinkles for 7 wk, then applied Fraction I to the treatment group for 5 wk and then tested skin thickness, minimum erythema dose and moisture content. In addition, Fraction I was high in collagen and HA biosynthesis and it was better than TGF-β in improving of the skin. When TNF-α caused MMP-1 activity in the CCD-986Sk cells, the whole ESMH and Fraction I proved to be effective in hindering the induction of collagenase depending on the concentration, and also showed outstanding effects in the suppression of skin aging. We found that the treatment group mice's UV-B radiation-induced skin damage was largely mitigated compared to that of the non-treatment group mice. Thus, we have concluded that EMSH helps to mitigate UV-B radiation-induced wrinkles, collagen, HA, MMP-1 activity and can be used for functional cosmetic materials.

The in vivo and in vitro effects of oriental herb extracts of Cassia obtusifolia, Taraxacum platycarpum and Ulmusmacrocarpa on anti-atopic allergic reaction were evaluated in this study. A mixture of these extracts exhibited more potent anti-allergic activities in human mast cells than those from individual extracts. The herbal mixture significantly inhibited the release of compound 48/80-induced β-hexosaminidase release in the human mast cell line, HMC-1. The mixture also suppressed the production of PMA and A23187-induced inflammatory cytokines in HMC-1 cells. To further investigate the in vivo effects of the herbal mixture, a Dermatophagoides farinae (DF)-induced atopic dermatitis mouse model was utilized. Oral administration of the herbal mixture significantly decreased the ear thickness and swelling in DF treated NC/Nga mice in a dose dependent manner. Furthermore, serum levels of IgE and interleukin-4 (IL-4) were significantly decreased, whereas interferon-gamma (IFN-γ) levels were increased in the mixture administrated groups when compared to the control. Taken together, our data indicate the possibility of using a mixture of the oriental herb extract to relieve symptoms of atopic dermatitis. © The Korean Society of Food Science and Technology.

Osteoporosis, an age associated skeletal disease, exhibits increased adipogenesis at the expense of osteogenesis from common osteoporotic bone marrow cells. In this study, black rice (Oryza sativa L.) extracts (BRE) were identified as osteogenic inducers. BRE stimulated the alkaline phosphatase (ALP) activity in both C3H10T1/2 and primary bone marrow cells. Similarly, BRE increased mRNA expression of ALP and osterix. Oral administration of BRE in OVX rats prevented decreases in bone density and strength. By contrast, BRE inhibited adipocyte differentiation of mesenchymal C3H10T1/2 cells and prevented increases in body weight and fat mass in high fat diet fed obese mice, further suggesting the dual effects of BRE on anti-adipogenesis and pro-osteogenesis. UPLC analysis identified cyanidin-3-O-glucoside and peonidin-3-O-glucoside as main anti-adipogenic effectors but not for pro-osteogenic induction. In mechanism studies, BRE selectively stimulated Wnt-driven luciferase activities. BRE treatment also induced Wnt-specific target genes such as Axin2, WISP2, and Cyclin D1. Taken together, these data suggest that BRE is a potentially useful ingredient to protect against age related osteoporosis and diet induced obesity. This journal is © The Royal Society of Chemistry.

Background: Inflammatory response on LPS and IFN-γ induced Macrophage Raw 264.7 cells was secreted NO (nitric oxide) and PGE2 (prostaglandin E2) though expression of iNOS and COX-2. And many pro-inflammatory cytokines (TNF-α, IL-1β, IL-6 etc.) was secreted on LPS and IFN-γ induced Macrophage Raw 264.7 cells, too. Atopy dermatitis was inflammatory skin disease with pruritus, xeroderma and specific eczema. Objective: We sought to effect of anti-inflammation and skin hydration of AF-343 on Macrophage Raw 264.7 cells and NC/Nga mice with Atopic Dermatitis. Methods: The immune response of Raw 264.7 cells were induced by LPS and IFN-γ. Then LPS and IFN-γ induced Raw 264.7 cells was measured NO, PGE2 production after treatment of different concentrations for AF-343. The related genes (iNOS, COX-2) for NO, PGE2 production were detected using Western blot in LPS and IFN-γ induced Raw 264.7 cells after treatment of different concentrations for AF-343. Pro-inflammatory cytokines were detected, too. NC/Nga mice as Atopy dermatitis model was induced atopy dermatitis. Then NC/Nga mice with atopy dermatitis were performed oral administration of AF-343 for 1weeks. After oral administration of AF-343, TEWL was measured on skin tissues of NC/Nga mice with atopy dermatitis according to whether were performed oral administration of AF-343 or not. And pro-inflammatory cytokines and IgE was measured in serum, protein of skin tissues of NC/Nga mice. Skin tissues of NC/Nga mice were performed H&E staining, immunohistochemical staining for PCNA, Involucrin and filaggrin. Results: LPS and IFN-γ induced Raw 264.7 cells was decreased NO, PGE2 production in dose-dependent after treatment of different concentrations for AF-343. The expression level of iNOS, COX-2 protein was decreased in dose-dependent, too. The related pro-inflammatory cytokines in media with LPS and IFN-γ induced Raw 264.7 cells were decreased after treatment of different concentrations for AF-343. TEWL level of NC/Nga mice skin (back, ear) with atopy dermatitis according to whether were performed oral administration of AF-343 or not was decreased in NC/Nga mice with atopy dermatitis group was performed oral administration by AF-343. When NC/Nga mice group with atopy dermatitis was performed oral administration by AF-343, induced pro-inflammatory cytokines and IgE expression in serum, protein of back, ear skin tissues of each NC/Nga mice group was decreased. H&E stained Skin tissues of NC/Nga mice was confirmed that thickness of epidermis, dermis were decreased in NC/Nga mice group with atopy dermatitis was performed oral administration by AF-343 than NC/Nga mice group with atopy dermatitis. The expression of PCNA, involucrin and filaggrin were decreased in NC/Nga mice group with atopy dermatitis was performed oral administration by AF-343 than NC/Nga mice group with atopy dermatitis as results of immunihistochemical staining using specific antibodies such as PCNA as cell proliferation marker, involucrin and filaggrin as keratinocytes differentiation markers for skin tissues (back, ear) of NC/Nga mice. Conclusion: We confirmed effect of anti-inflammation and skin hydration of AF-343 on Macrophage Raw 264.7 cells and NC/Nga mice with Atopic Dermatitis. In conclusion, AF-343 is expecting as therapeutics for atopic dermatitis.

This study was conducted to examine the effects of eggshell membrane hydrolysates (ESMH) on the anti-inflammatory, anti-wrinkle, anti-microbial activity, and moisture-protection for cosmetic use. Whole ESMH (before fractionation), and fraction I (>10 kDa), fraction II (3-10 kDa), and fraction III (<3 kDa) of the hydrolysates were assessed in this experiment. As lipopolysaccharide (LPS) and IFN-γ caused the inflammation on Raw264.7 cell, whole ESMH and fraction I showed to be effective in inhibiting the induction of cell inflammation depending on the concentration, and also showed outstanding effect to suppress the skin inflammation. Fraction I inhibited collagenase and elastase activities to a greater extent than the other fractions, while all fractions had antibiotic effects at concentrations of 10 mg/disc and 20 mg/disc. In addition, it showed the moisture protection effects of skin on the holding amount and losing amount of moisture in upper-inner arm of the human body with a relatively low loss rate in skin, which confirmed that the hydrolyzed fractions of ESM helps to form the superior protective layer of moisture. It was concluded that ESMH fractions with different molecular weights, especially the 10 kDa fraction, have anti-lipopolysaccharide, anti-IFN-γ-induced inflammation, anti-collagenase and elastase activities, and thus can be used as a cosmetic agent to protect skin.

Extract of Taraxacum platycarpum (AF-343) has been reported to have several biological properties such as skin hydration and anti-inflammatory effects. Although clinical evidences of skin hydration and antiinflammatory effect were proven in clinical trial, precise mechanism of skin hydration was not fully understood yet. In this study, we have focused skin hydration mechanism related filaggrin, collagen, and matrix metalloproteinase (MMP) in vitro and animal study. Herein, skin hydration mechanism of AF-343 is due to recovery of filaggrin in mice model and increased production of collagen with suppression of matrix MMP in vitro fibroblast cell line.

The present invention relates to a Eupatorium spp. extract having anti-obesity effects as a result of decreasing adipocytes and increasing osteoblasts, as well as the effects of preventing bone disease or fractures by increasing osteoblasts and of preventing osteoporosis by decreasing adipocytes and increasing osteoblasts by the same proportion in mesenchymal stem cells. DCM fraction layers of a Eupatorium spp. stem extract collected on a monthly basis and Eupatorium spp. stem extract collected only in September may inhibit the activity of PPAR, AP2, CD36, adiponectin C/EBP, and LPL, which serve as significant factors for adipocyte differentiation in C3H10T1/2 cells and primary mesenchymal stem cells, which are pluripotent stem cell lines, and may increase the activity of ALP, osterix, CO1I and RUNX2, which serve as significant factors for osteoblast differentiation. The Eupatorium spp. extract of the present invention exhibits the effects of increasing bone mineral density (BMD) and decreasing adipocytes in bone marrow in an osteoporosis animal model experiment involving an ovariectomy, and therefore may be used as a useful material for preventing and treating osteoporosis.
