Abstract:
:To study in vivo phosphorylation of N-methyl-D-aspartate (NMDA) glutamate receptors and the recruitment of protein kinase C isoforms during acute hypoxia, dorsocaudal brainstem lysates were harvested from conscious rats exposed to either room air or hypoxia (10% O2 for 5 and 15 min). Increased phosphorylation of the NR-1 subunit at serine residue 896 occurred during hypoxia and was blocked by pre-treatment with MK-801. Immunoblots of soluble and particulate fractions revealed subcellular translocation for PKC-beta, -gamma, -delta, -epsilon, and -iota during hypoxia with no changes in PKC-alpha, -mu, and -zeta. Translocation of PKC-beta, -delta and -epsilon was selectively attenuated following MK-801. We demonstrate that hypoxia leads to PKC-mediated activation of NMDA receptors in the brainstem, and that PKC-beta, -delta and -epsilon are the most likely candidates for NR-1 phosphorylation.
