Changes in the Tyrosine Phosphorylation of Mitogen‐Activated Protein Kinase in the Rat Hippocampus During and Following Severe Hypoglycemia
Forskningsoutput: Tidskriftsbidrag › Debate/Note/Editorial
Abstract: The changes in the levels of tyrosine‐phosphorylated proteins in the cytosolic fraction of the rat hippocampus subjected to severe hypoglycemia were analyzed. A marked increase in tyrosine phosphorylation of a 43‐kDa protein was observed at 30 min of isoelectric EEG and 30 min and 1 h of recovery. Immunostaining of the same blot with antibody against mitogen‐activated protein (MAP) kinase demonstrated a double band of ∼42 and 43 kDa. The increased tyrosine phosphorylation of MAP kinase during hypoglycemic coma and the early recovery period suggests that MAP kinase may be involved in neuronal degeneration and repair.
