Role of protein kinase C in renal vasoconstriction caused by angiotensin II [PDF]
In this study we have examined the subcellar pathways along which angiotensin II (ANG II) causes renal vasoconstriction. Using the isolated perfused rat kidney model, we found that renal vasoconstriction produced by ANG II (100 pM) was not altered by the

Cochlioquinone A, an Inhibitor of Diacylglycerol Kinase.
The effects of cochlioquinone A, isolated from Drechslera sacchari, were studied in vitro and in vivo. This compound specifically inhibited diacylglycerol kinase activity with Ki = 3.1 microM. The kinetics revealed that cochlioquinone A inhibited diacylglycerol kinase in competition with ATP, and non-competitively with diacylglycerol.

Inhibition of native TRPC6 channel activity by phosphatidylinositol 4,5-bisphosphate in mesenteric artery myocytes [PDF]
The present work investigates the effect of phosphatidylinositol-4,5-bisphosphate (PIP2) on native TRPC6 channel activity in freshly dispersed rabbit mesenteric artery myocytes using patch clamp recording and co-immunoprecipitation methods.

Targeting sphingosine kinase 1 in carcinoma cells decreases proliferation and survival by compromising PKC activity and cytokinesis [PDF]
Sphingosine kinases (SK) catalyze the phosphorylation of proapoptotic sphingosine to the prosurvival factor sphingosine 1-phosphate (S1P), thereby promoting oncogenic processes.

Diacylglycerol Kinase-ε: Properties and Biological Roles
In mammals there are at least 10 isoforms of diacylglycerol kinases (DGK). All catalyze the phosphorylation of diacylglycerol (DAG) to phosphatidic acid (PA). Among DGK isoforms, DGKε has several unique features.

Protein Kinase C as a Molecular Machine for Decoding Calcium and Diacylglycerol Signals [PDF]
The specificity of many signal transduction pathways relies on the temporal coordination of different second messenger signals. Here we found a molecular mechanism which guarantees that conventional protein kinase C (PKC) isoforms are sequentially ...

Diacylglycerol kinase zeta positively controls the development of iNKT-17 cells. [PDF]
Invariant natural killer T (iNKT) cells play important roles in bridging innate and adaptive immunity via rapidly producing a variety of cytokines. A small subset of iNKT cells produces IL-17 and is generated in the thymus during iNKT-cell ontogeny.

Ks1, an epithelial cell-specific gene, responds to early signals of head formation in Hydra [PDF]
As a molecular marker for head specification in Hydra, we have cloned an epithelial cell-specific gene which responds to early signals of head formation.

MicroRNA-34a enhances T cell activation by targeting diacylglycerol kinase ζ. [PDF]
The engagement of the T cell receptor (TCR) induces the generation of diacylglycerol (DAG), an important second messenger activating both the Ras/Erk and PKCθ/NFκB pathways.
