Lipid metabolism in visceral fat cells is correlated with metabolic syndrome and cardiovascular diseases. Okadaic-acid, a 38-carbon fatty acid isolated from the black sponge Halichondria okadai , can stimulate lipolysis by promoting the phosphorylation of several proteins in adipocytes. However, the mechanism of okadaic acid-induced lipolysis and the effects of okadaic acid on lipid-droplet

Literature in this Area Tocris offers the following scientific literature in this area to showcase our products. Abstract: Okadaic acid (OA) is one of the most frequent and worldwide distributed marine toxins. It is easily accumulated by shellfish, mainly bivalve mollusks and fish, and, subsequently, can be consumed by humans causing alimentary intoxications. OA is the Okadaic acid, an inhibitor of protein phosphatase 1 and 2A, induces premature separation of sister chromatids during meiosis I and aneuploidy in mouse oocytes in vitro. Okadaic acid promotes epithelial‐mesenchymal transition of hepatocellular carcinoma cells by inhibiting protein phosphatase 2A.

Sammanfattning: Bivalve molluscs accumulate toxins of the okadaic acid (OA) and pectenotoxin (PTX) groups, which are frequently found in Dinophysis spp.

[1] [2] Okadaic acid eliminate metazoan symbionts/ parasites by apoptosis [3] . Okadaic acid is a marine sponge toxin which potently inhibits certain serine/threonine protein phosphatases. This cell permeable inhibitor targets the multiple isoforms of PP1 (IC50 = 10-50 nM), both isoforms of PP2A (IC50 = 0.5 nM) and PP3 (IC50 Okadaic acid also enhanced the neurite degeneration of NGF-primed PC12 cells, indicating that continual phosphatase activity is required to maintain neurites. Taken together, these results reveal the presence of an okadaic acid-sensitive pathway in neurite outgrowth and imply that protein phosphatase plays a positive role in regulating the neuritogenic effects of NGE. Okadaic acid significantly increased phosphorylation of CaMKII; indicating a major role of PP1 in CaMKII dephosphorylation.

Okadaic acid

Okadaic acid is a naturally occuring polyether toxin produced by marine dinoflagellates. It is a potent and selective inhibitor of protein phosphatases, inhibiting PP2A completely at 1nM and PP1 at higher concentrations (IC 50 =10-15nM). PP2B is much less sensitive to okadaic acid than PP1, while PP2C is …

Okadaic acid

Okadaic acid has been an important tool in the analysis of PP function. A product of dinoflagellate metabolism, okadaic acid is the causative agent of diarrhetic shellfish poisoning. This toxin potently and specifically inhibits PP-1 and PP-2A, although with different IC 50 concentrations. Despite sharing similar structure and catalytic The three main results of the study were as follows: (1) The saxitoxin-group toxins, okadaic acid and analogues, and pectenotoxins were the major phycotoxin residues found in scallops; (2) Six kinds of toxic microalgae were identified, Protoperidinium spp., Gonyaulax spp., and Alexandrium spp.

General information: High concentrations of shellfish toxins can accumulate in filter feeders such as clams, mussels, and … Okadaic acid is a toxic polyether compound of a C 38 fatty acid (Fig. 1).It is isolated from the black sponge, Halichondria okadai (Kadota), however, it is thought to be produced by marine dinoflagellates that attach to the black sponge.Okadaic is derived from the name of a Japanese educator Yaichiro Okada. When the structure of okadaic acid was elucidated in 1981, Paul Scheuer at the Okadaic acid is a marine sponge toxin which potently inhibits certain serine/threonine protein phosphatases. This cell permeable inhibitor targets the multiple isoforms of PP1 (IC50 = 10-50 nM), both isoforms of PP2A (IC50 = 0.5 nM) and PP3 (IC50 = 4 nM).[1],[2],[3] It is a very weak inhibitor of PP2B (IC50 > 2 μM) and does not inhibit PP2C or other phosphatases.[1],[3 ]Presumably through Lipid metabolism in visceral fat cells is correlated with metabolic syndrome and cardiovascular diseases.
