Akt Mediates Cytoprotection of Endothelial Cells by Vascular Endothelial Growth Factor in an Anchorage-dependent Manner
Open accessAbstract
Regulation of endothelial cell apoptosis is a critical modulator of normal and pathological angiogenesis. In this study, we examined the role of the protein kinase Akt/PKB in endothelial cell survival in response to growth factor and matrix attachment signals. Vascular endothelial growth factor(VEGF)-induced cytoprotection of endothelial cell monolayers correlated with the wortmannin-sensitive induction of Akt activity. Transfection of an adenovirus expressing a dominant-negative Akt mutant decreased endothelial cell viability in the presence of VEGF. Conversely, adenoviral transduction of wild-type Akt facilitated the cell survival effects of VEGF, whereas transduction of constitutively active Akt conferred endothelial cell survival in the absence of VEGF. Constitutively active Akt also conferred survival to endothelial cells in suspension culture, whereas stimulation with VEGF did not. In suspension cultures, VEGF stimulation was unable to activate Akt, and Akt protein levels were repressed in cells undergoing anoikis. These data suggest that cross-talk between growth factor- and anchorage-dependent signaling pathways are essential for Akt activation and endothelial cell survival.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
