Substrate-induced changes in the lipid content of ischemic and reperfused myocardium. Its relation to hemodynamic recovery.

abstract：RATIONALE:We previously reported that vascular endothelial growth factor (VEGF)-induced binding of VEGF receptor 2 (VEGFR2) to epsins 1 and 2 triggers VEGFR2 degradation and attenuates VEGF signaling. The epsin ubiquitin interacting motif (UIM) was shown to be required for the interaction with VEGFR2. However, the mole...
