Adrenomedullin (ADM) is a vasoactive peptide that was recently localized in renal glomeruli. In the present study we explored whether ADM stimulates cAMP system in glomerular mesangial cells (MC) and whether it can via "negative-crosstalk" inhibit the mitogen-activated protein kinase (MAPK) and thus suppress proliferation of MC. We found that ADM elicited(More)
We have previously reported anti-obesity effects of Lysimachia foenum-graecum in high-fat diet (HFD)-induced obesity model. Here we isolated a triterpene saponin foenumoside B as an active component of L. foenum-graecum. Foenumoside B blocked the differentiation of 3T3-L1 preadipocytes in a dose-dependent manner with an IC50 of 0.2 μg/ml in adipogenesis(More)
A protease from the venom of the Southern Copperhead snake (Agkistrodon contortrix contortrix) that activates protein C was purified to homogeneity by a combination of sulfopropyl (SP)-Sephadex C-50, Sephadex G-150 and Mono-S column chromatography. The purified enzyme is a glycoprotein, and migrated as a single band in sodium dodecylsulfate-polyacrylamide(More)
The fruit of Terminalia chebula Retzius has been used as a panacea in India and Southeast Asia but its biological activities have not been fully elucidated. Here we report anti-arthritic and analgesic effect of NDI10218, a standardized ethanol extract of Terminalia chebula, on collagen-induced arthritis and acetic acid-induced writhing model, respectively.(More)
Protein phosphatase 5 (PP5) is a serine/threonine phosphatase that belongs to the PPP family phosphatases. PP5 and the other phosphatases of the PPP family share significantly similar catalytic domain structure. Due to this structural similarity, natural competitive inhibitors such as okadaic acid and cantharidin exhibit broad specificity over the PPP(More)
The need for efficient high-throughput gene delivery system for mammalian cells is rapidly increasing with the growing request for functional genomics studies and drug discoveries in various physiologically relevant systems. However, plasmid-based gene delivery has limitations in transfection efficiency and available cell types. Viral vectors have great(More)
