Productivity of seagrasses can be controlled by physiological processes, as well as various biotic and abiotic factors that influence plant metabolism. Light, temperature, and inorganic nutrients affect biochemical processes of organisms, and are considered as major factors controlling seagrass growth. Minimum light requirements for seagrass growth vary(More)
Schisandra chinensis has a long-standing history of medicinal use as a tonic, a sedative, an anti-tussive, and an anti-aging drug. Nevertheless, the antagonistic effects of S. chinensis against lipopolysaccharide (LPS)-stimulated responses have not yet been studied. In this study, we investigated whether water extract of S. chinensis fruit (WESC) has the(More)
Little is known about whether trans-isoferulic acid (TIA) regulates the production of lipopolysaccharide (LPS)-induced proinflammatory mediators. Therefore, we examined the effect of TIA isolated from Clematis mandshurica on LPS-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production in BV2 microglial cells. We found that TIA inhibited the(More)
Verrucarin A (VA) is a member of the family of macrocyclic trichothecenes, which exhibit anti-cancer and immune-modulating activities. However, VA has not yet been demonstrated to be involved in the sensitization of tumor necrosis factor-alpha (TNF-α)-mediated apoptosis. In the present study, we found that VA triggers TNF-α-induced apoptosis in human breast(More)
Little is known about the molecular mechanism through which 18β-glycyrrhetinic acid (GA) inhibits metastasis and invasion of cancer cells. Therefore, this study aimed to investigate the effects of GA on the expression of matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor (VEGF) in various types of cancer cells. We found that treatment(More)
Though camptothecin (CPT) possesses potent anti-inflammatory, immunomodulatory, anticancerous, and antiproliferative effects, little is known about the mechanism by which CPT regulates the expression of matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor (VEGF). Therefore, the current study aimed to investigate the effects of CPT on(More)
Photoacclimatory responses of the seagrass Zostera marina in the intertidal and subtidal zones were investigated by measuring chlorophyll a fluorescence parameters, photosynthetic pigments, leaf δ13C values, and shoot morphology in two bay systems. Intertidal plants had higher carotenoid concentrations than subtidal plants to avoid photodamage under excess(More)
We identified single nucleotide polymorphism (SNP) markers in the laccase gene to establish a line-diagnostic system for shiitake mushrooms. A total of 89 fungal isolates representing four lines, including Korean registered, Korean wild type, Chinese, and Japanese lines, were analyzed. The results suggest that SNP markers in the laccase gene can be useful(More)
Caffeic acid phenethyl ester (CAPE) exhibits various pharmaceutical properties, including anti-bacterial, anti-inflammatory, anti-viral, anti-cancer, and anti-oxidative activity. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been a promising anti-cancer agent that preferentially induces cancer cell apoptosis with negligible(More)
Porphyra spp. (currently Porphyra and Pyropia) are major sources of seafood globally. In this study, we investigated the effects of ammonium concentration, water temperature, and thallus stocking density on N-ammonium uptake rate (NUR), tissue nutrients content, N–NH4 + filtration efficiency (NUE: nitrogen uptake efficiency %) of Pyropia yezoensis at a(More)
