Abstract: Disclosed is an AMPK activating material used for improving and treating metabolic syndrome, in which AMPK (AMP-activated protein kinase) is a main enzyme for regulating an energy sensor and lipid/glucose metabolism in the body. The activation of AMPK inhibits the synthesis of fat and cholesterol, and accelerates the reduction of body fat and blood glucose, thereby improving obesity, diabetes, and hyperlipidaemia. The disclosed AMPK activating material contains, as active ingredients having an improving and treating effect on metabolic syndrome, including obesity, diabetes, and hyperlipidaemia, a novel compound 2?,3?,12?-trihydroxydammar-20(22)-E,24-diene-3-O-[?-D-glucopyranosyl-(1?)-?-D-glucopyranoside], named Damulin A, and a novel compound 2?,3?,12?-trihydroxydammara-20,24-diene-3-O-[?-D-glucopyranosyl-(1?)-?-D-glucopyranoside], named Damulin B.

Abstract: Disclosed is a pharmaceutical composition containing obovatol represented by Formula 1 and its derivatives. The obovatol and its derivatives effectively increase the activity of AMPK (AMP-activated protein kinase) that plays an important role in diabetes and metabolic syndrome, and thus may be variously used in treating diabetes and metabolic syndrome. (In Formula 1, R1, R2 and R3 are the same as defined above).

Abstract: The present application describes a composition that includes an extract of Gynostemma pentaphyllum used to treat insulin resistance syndrome, obesity, hypertriglyceridemia, as well as decrease body fat mass.

Abstract: The present invention relates to a cytosolic isocitrate dehydrogenase, its gene, and its use in the treatment of obesity, hyperlipidemia, and fatty liver. The expression of the IDPc gene and the concomitant increase in IDPc level bring about an increase in the cellular level of NADPH, which causes the lipid deposition in adipocytes, leading to obesity and fatty liver. A decrease in the cellular level of NADPH, resulting from the suppression of the gene expression of IDPc, has the effect of inhibiting the lipid deposition in adipocytes. Further, by taking advantage of the suppressive or inhibitory effects of isocitrate dehydrogenase inhibitors, pharmaceutically effective materials for the prophylaxis and treatment of obesity, hyperlipidemia and fatty liver can be developed.

Abstract: The present invention relates to a pharmaceutical composition for prevention and treatment of arthritis and a screening method thereof. More precisely, the present invention relates to a pharmaceutical composition for prevention and treatment of arthritis which contains extracellular signal regulated protein kinase (ERK) or its upstream signal transduction molecule MAP kinase kinase (MEK) activity inhibitor, and a screening method for the pharmaceutical composition for prevention and treatment of arthritis through searching the ERK or MEK activity inhibitors.

Abstract: The present invention relates to a zebrafish HuC promoter with its 5′-flanking region which directs the neuron-specific expression of structural genes, a transgenic animal that shows the neuron-specific expression of GFP (green fluorescence protein) under the regulation of the HuC promoter, and a method for screening neurogenesis mutants in zebrafish by use of the transgenic animal. The HuC promoter with its 5′-flanking region can be used in the study of the regulatory mechanism responsible for the differentiation of the nervous system. Additionally, the HuCP-GFP transgenic zebrafish enables the direct identification of neurogenesis and axonogenesis, as well as being a valuable tool for isolating and analyzing neurogenesis mutants in live zebrafish with ease.
