Nine diacylglycerol kinase (DGK) isozymes have been identified. However, our knowledge of their individual functions is still limited. Here, we demonstrate the role of DGKgamma in regulating Rac1-governed cell morphology. We found that the expression of kinase-dead DGKgamma, which acts as a dominant-negative mutant, and inhibition of endogenous DGKgamma(More)
We report a rare case of postoperative infarction in the territory of the contralateral recurrent artery of Heubner (RAH) after surgery. A 67-year-old male was treated by the right pterional approach with clipping surgery for an unruptured anterior communicating artery aneurysm projecting inferiorly. Postoperative CT scan revealed infarctions in the left(More)
Although nine diacylglycerol kinase (DGK) isozymes have been identified, our knowledge of their individual functions is still limited. Here we report that the levels of DGKgamma mRNA/protein in human leukemia HL-60 and U937 cells were rapidly and markedly decreased upon cellular differentiation into macrophages. In contrast, the enzyme expression remained(More)
Diacylglycerol kinase (DGK) plays an important role in signal transduction through modulating the balance between two signaling lipids, diacylglycerol and phosphatidic acid. DGKdelta (type II isozyme) contains a pleckstrin homology domain at the N terminus and a sterile alpha motif domain at the C terminus. We identified another DGKdelta isoform (DGKdelta2,(More)
