Zhang J, Svehlikova V, Bao Y, Howie AF, Beckett GJ, Williamson G: Synergy between sulforaphane and selenium in the induction of thioredoxin reductase 1 requires both transcriptional and translational modulation. Carcinogenesis. 2003 Mar;24(3):497-503.
Modulation of TrxR1 mRNA by sulforaphane was glutathione and protein kinase C-dependent, as L-buthionine-S,R-sulfoximine (a specific inhibitor of glutathione synthesis), and the protein kinase C inhibitor 1-(5-isoquinolinesulfonyl)-2-methyl-piperazine, significantly reduced the induction. |

Vidulescu C, Mironneau J, Mironneau C, Popescu LM: Messenger molecules of the phospholipase signaling system have dual effects on vascular smooth muscle contraction. J Cell Mol Med. 2000 Jul-Sep;4(3):196-206.
However, when added during noradrenaline-induced plateau, phospholipase D shortly potentiated it. b) The protein kinase C activator, phorbol dibutyrate potentiated both the exogenous phospholipase C-induced contraction and the noradrenaline-induced plateau, while the protein kinase C inhibitor 1-(-5-isoquinolinesulfonyl)-2-methyl-piperazine relaxed the plateau. c) When added before noradrenaline, indomethacin inhibited both phasic and tonic contractions, but when added during the tonic contraction shortly potentiated it. |
