The instability of DA at the neutral pH of the cytosol causes the forma- tion of toxic aminochromes, and these species are not formed when DA is protonated at the acidic pH of the storage ... counter. Values are the mean of six replicates. The specific uptake was determined by subtracting the uptake counts in the absence of inhibitor from the upta...

... in all of these conditions [22]. In the trau- matically injured brain, however, the synthesis of MT1 and MT2, as well as the synthesis of GIF, are up-regu- lated by reactive astrocytes in the vicinity ... fine processes of these cells. Astrocytic synthesis of GIF is mainly found in the cortex, brainstem and spinal cord [6]. Additionally however, there are also consistent...

On the basis of the crystal structure of the tyrosine kinase domain of the IR in complex with the PIR ⁄ BPS domain of Grb14, Depetris ... Although the interaction of Grb14 with the IR is probably the major determi- nant of the insulin-induced membrane translocation of Grb14, several lines of e...
