Ethanol extract of Lithospermum erythrorhizon Sieb. et Zucc. promotes osteoblastogenesis through the regulation of Runx2 and Osterix.

Bone remodeling and homeostasis are largely the result of the coordinated action of osteoblasts and osteoclasts. Osteoblasts are responsible for bone formation. The differentiation of osteoblasts is regulated by the transcription factors, Runx2 and Osterix.

UPLC-MS/MS-Based Profiling of Eicosanoids in RAW264.7 Cells Treated with Lipopolysaccharide.

While both the pro- and anti-inflammatory effects of several eicosanoids have been widely studied, the degree of inflammation in cells that results from various eicosanoids has yet to be comprehensively studied. The objective of this study was to assess the effect of lipopolysaccharide (LPS) treatment on eicosanoid content in RAW264.7 cells.

Isolation and identification of phytochemicals and biological activities of Hericium ernaceus and their contents in Hericium strains using HPLC/UV analysis.

Ethnopharmacological Relevance: Hericium ernaceus has been traditionally used for the treatment of dyspepsia, gastric ulcer and enervation in traditional Chinese medicine for a long time.

Aim Of The Study: To examine the effect of Hericium strains on their ability to inhibit LPS and interferon-γ induced NO production in cell culture and the bioassay correlation of hericenone C, D, F, isolated from H. ernaceus.

Hepatoprotective Effect and Synergism of Bisdemethoycurcumin against MCD Diet-Induced Nonalcoholic Fatty Liver Disease in Mice.

Nonalcoholic fatty liver disease (NAFLD), the hepatic manifestation of the metabolic syndrome, has become one of the most common causes of chronic liver disease over the last decade in developed countries. NAFLD includes a spectrum of pathological hepatic changes, such as steatosis, steatohepatitis, advanced fibrosis, and cirrhosis. Bisdemethoxycurcumin (BDMC) is polyphenolic compounds with a diarylheptanoid skeleton, curcumin close analogues, which is derived from the Curcumae Longae Rhizoma.

A synthetic chalcone derivative, 2-hydroxy-3',5,5'-trimethoxychalcone (DK-139), suppresses the TNFα-induced invasive capability of MDA-MB-231 human breast cancer cells by inhibiting NF-κB-mediated GROα expression.

2-Hydroxy-3',5,5'-trimenthoxyochalcone (DK-139) is a synthetic chalcone-derived compound. This study evaluated the biological activity of DK-139 on the inhibition of tumor metastasis. Growth-regulated oncogene-alpha (GROα) plays an important role in the progression of tumor development by stimulating angiogenesis and metastasis.

Global Profiling of Various Metabolites in Platycodon grandiflorum by UPLC-QTOF/MS.

In this study, a method of metabolite profiling based on UPLC-QTOF/MS was developed to analyze Platycodon grandiflorum. In the optimal UPLC, various metabolites, including major platycosides, were separated well in 15 min. The metabolite extraction protocols were also optimized by selecting a solvent for use in the study, the ratio of solvent to sample and sonication time.

Melanin Biosynthesis Inhibition Effects of Ginsenoside Rb2 Isolated from Panax ginseng Berry.

Ginsenoside Rb2 (Gin-Rb2) was purified from the fruit extract of Panax ginseng. Its chemical structure was measured by spectroscopic analysis, including HR-FAB-MS, (1)H-NMR, and IR spectroscopy. Gin-Rb2 decreased potent melanogenesis in melan-a cells, with 23.

Postharvest strategies for deoxynivalenol and zearalenone reduction in stored adlay (Coix lachryma-jobi L.) grains.

Improperly practiced postharvest procedures can pose mycotoxin-related risks in the production of medicinal herbs. As a health food with pharmacological supplements, cereal-based adlay has been broadly used in oriental medical practice. Compared with the standard production protocol, three provisional critical control points (CCPs) in the conventional procedure were identified and assessed for mycotoxin contamination in the adlay from small farms in Korea.

Combination Therapy of Sophoraflavanone B against MRSA: In Vitro Synergy Testing.

Sophoraflavanone B (SPF-B), a known prenylated flavonoid, was isolated from the roots of Desmodium caudatum. The aim of this study was to determine the antimicrobial synergism of SPF-B combined with antibiotics against methicillin-resistant Staphylococcus aureus (MRSA). MRSA, a multidrug-resistant pathogen, causes both hospital- and community-acquired infections worldwide.

Induction of human microsomal prostaglandin E synthase 1 by activated oncogene RhoA GTPase in A549 human epithelial cancer cells.

Oncogenic RhoA GTPase has been investigated as a mediator of pro-inflammatory responses and aggressive carcinogenesis. Among the various targets of RhoA-linked signals, pro-inflammatory prostaglandin E(2) (PGE(2)), a major prostaglandin metabolite, was assessed in epithelial cancer cells. RhoA activation increased PGE(2) levels and gene expression of the rate-limiting PGE(2) producing enzymes, cyclooxygenase-2 and microsomal prostaglandin E synthase 1 (mPGES-1).

Identification of genes possibly related to storage root induction in sweet potato.

To identify genes related to initiation of storage root development in sweet potato, a cDNA library was constructed with early stage storage roots (0.3-1 cm in diameter). Single-pass sequences of the 5' ends of 2859 sweet potato cDNA clones were assembled into 483 clusters and 442 singletons.
