Changes in tyrosine phosphorylation in neocortex following transient cerebral ischaemia.


Growth factor receptors activate protein tyrosine kinases, which are important for cell growth and survival. The protein tyrosine kinase (PTK) activity and the levels of phosphotyrosine (Ptyr) containing proteins were studied in the rat neocortex exposed to 15 min of transient cerebral ischaemia. The levels of the Ptyr containing proteins increase during… (More)
