-
Tat-induced SMO activation, involving the polyamine-sensitive subtype of the NMDA receptor, the activation is completely prevented by the NMDAR antagonist MK-801. Mechanism, overview
-
N1,N11-diethylnorspermine
-
polyamine analogue with clinical relevance as an experimental anticancer agent. Treatment of human C-28/I2 chondrocytes rapidly induces spermidine/spermine N1-acetyltransferase and spermine oxidase activities, and down-regulates ornithine decarboxylase. The treatment does not provoke cell death and caspase activation when given alone for 24 h, but causes a caspase-3 and -9 dependent apoptosis in chondrocytes further exposed to cycloheximide. The simultaneous addition of N1,N11-diethylnorspermine and cycloheximide rapidly increases caspase activity in C-28/I2 cells in the absence of spermidine/spermineN1-acetyltransferase and spermine oxidase induction or significant reduction of polyamine levels
