Expression data from ERK1/2 null endothelial cells

ABSTRACT: Angiogenesis is a complex process orchestrated by both growth factors and cell adhesion to the extracellular matrix and is initiated by focal degradation of the vascular basement membrane with subsequent migration and proliferation of endothelial cells (EC). The Ras/Raf/MEK/ERK pathway is critical for EC function during angiogensis. Although in vitro studies implicate ERK1 and ERK2 in EC survival, their precise role in EC function in vivo remains poorly defined. Cre/loxP technology was used to inactivate Erk1 and Erk2 in EC during murine development, resulting in embryonic lethality due to a drastic reduction in angiogenesis. The angiogenic defect was linked to diminished EC proliferation and migration, but not to increased cell apoptosis. Expression of key cell cycle regulators was
