Widdrol, a natural sesquiterpene present in Juniperus sp., has been shown to exert anticancer and antifungal effects. Emerging evidence has suggested that AMP-activated protein kinase (AMPK), which functions as a cellular energy sensor, is a potential therapeutic target for human cancers. In this study, we found that(More)
The effects of temperature, irradiance, and daylength on Sargassum horneri growth were examined at the germling and adult stages to discern their physiological differences. Temperature–irradiance (10, 15, 20, 25, 30°C × 20, 40, 80 μmol photons m−2s−1) and daylength (8, 12, 16, 24 h) experiments were carried out. The germlings and blades of S. horneri grew(More)
PURPOSE alpha-lipoic acid is an essential cofactor for mitochondrial respiratory enzymes that improves mitochondrial function. We previously reported that alpha-lipoic acid markedly reduced body weight gain in rodents. The purpose of this study was to determine whether alpha-lipoic acid reduces body weight in obese human subjects. METHODS in this(More)
Costunolide, a sesquiterpene lactone isolated from the root of Saussurea lappa Clarke, is known to have a variety of biological activities, including anti-carcinogenic and anti-fungal activities. Here, we demonstrated the inhibitory effect of costunolide on the protein and mRNA expression of interleukin-1beta (IL-1beta) in LPS-stimulated RAW 264.7 cells. We(More)
Lung cancer is the leading cause of cancer-related death among men and women in the world. Despite the aggressive treatment with surgery, radiation and chemotherapy, the long term survival for lung cancer patients remains low. In this study, the anti-tumor activity of cytokine-induced killer (CIK) cells against human lung cancer was evaluated in vitro and(More)
(R)-4-(3,4-Dihydro-8,8-dimethyl)-2H,8H-benzo[1,2-b:3,4-b'] dipyran-3yl)-1,3-benzenediol (glabridin) is known to have anti-inflammatory, antimicrobial, and cardiovascular protective activities. In the present study, we report the inhibitory effect of glabridin on intercellular adhesion molecule-1 (ICAM-1) expression in tumor necrosis factor-alpha(More)
The acidic polysaccharide (PL) from Phellinus linteus is an immunostimulator that has therapeutic activity against cancers. Here, we show that PL markedly inhibits melanoma cell metastasis in mice, and report that PL directly inhibits cancer cell adhesion to and invasion through the extracellular matrix, but that it has no direct effect on cancer cell(More)
Mitochondrial dysfunction is known as one of causative factors in Alzheimer's disease (AD), inducing neuronal cell death. Mitochondria regulate their functions through changing their morphology. The present work was undertaken to investigate whether Amyloid β (Aβ) affects mitochondrial morphology in neuronal cells to induce apoptosis. Aβ treatment induced(More)
Multidrug resistance mediated by the drug efflux protein, P-glycoprotein (P-gp), is one of the principal mechanisms by which tumor cells escape the cell death induced by chemotherapeutic agents. In our previous study, we demonstrated that KBH-A42 [N-hydroxy-3-(2-oxo-1-(3-phenylpropyl)-1,2,5,6-tetrahydropyridin-3-yl)propanamide], a synthetic histone(More)
The pectic polysaccharide (angelan) of Angelica gigas Nakai is an immunostimulator that activates the immune functions of B cells and macrophages. Here we investigated the effect of angelan on tumor growth and metastasis. Angelan was found to significantly prolong the survival rate of B16F10-implanted mice and to reduce the frequency of pulmonary metastasis(More)
