Biosci Rep (2018) 38 (5): BSR20171459.
Published: 07 September 2018
...Sushant Kumar Das; Yi Feng Yuan; Mao Quan Li To explore whether or not inhibition of protein kinase C βII (PKC βII) stimulates angiogenesis as well as prevents excessive NETosis in diabetics thus accelerating wound healing. Streptozotocin (STZ, 60 mg/kg/day for 5 days, i.p.) was injected to induce...

... acid oversupply to hepatocytes can establish a vicious cycle involving diminished protein folding, endoplasmic reticulum (ER) stress, insulin resistance and further lipogenesis. This commentary discusses the recent findings of Lai et al. published in Bioscience Reports , that implicate protein kinase C...

...Anita Sjö; Karl-Eric Magnusson; Kajsa Holmgren Peterson We show here, that activation of protein kinase C by the phorbol ester PMA improves barrier function in colon carcinoma (HT 29) cells. By contrast, in canine kidney (MDCK I) cells it caused increased permeability and opening of tight junctions...

The protein kinase C (PKC) inhibitor, Ro-31-8220, and downregulation of PKC by prolonged incubation of cells with 12-O-tetradecanoylphorbol-13-acetate (TPA), had no effect on the ability of insulin to stimulate protein synthesis whilst completely blocking the response...

... that their action was by activation of protein kinase C rather than by arachidonate release and prostaglandin formation. Ibuprofen, an inhibitor of cyclo-oxygenase failed to block the effects of insulin whereas a second cyclo-oxygenase inhibitor, indomethacin had only a partial inhibitory effect. The protein kinase...

...P. García-Paramio; M. J. Carmena; F. Román; B. Colás; J. C. Prieto The properties of protein kinase C (PKC) activity have been studied in cytosolic and membrane fractions from rat and human prostate. Ion exchange chromatography indicated the existence of different PKC isoforms, PKC from rat ventral...

... and A 23187, two calcium ionophores, synergistically potentiated the stimulatory effect of IL-1β on PGE 2 formation. Three different phorbol esters known to activate protein kinase C also synergistically potentiated the action of IL-1β on PGE 2 formation. Exogenously added arachidonic acid significantly...

...Richard M. Epand; Christine McCallum Retinol has little effect on the activity of protein kinase C. However, air oxidation of retinol produces products which are inhibitory to this enzyme. These results are consistent with a suggestion that the activity of protein kinase C is modulated by the bulk...
