Abstract

Endothelial cell (EC) migration in response to vascular endothelial growth factor (VEGF) is a critical step in both physiological and pathological angiogenesis. Although VEGF signaling has been extensively studied, the mechanisms by which VEGF-dependent reactive oxygen species (ROS) production affects EC signaling are not well understood. The aim of this study was to elucidate the involvement of Nox2- and Nox4-dependent ROS in VEGF-mediated EC Ca(2+) regulation and migration. VEGF induced migration of human aortic ECs into a scratch wound over 6 h, which was inhibited by overexpression of either catalase or superoxide dismutase (SOD). EC stimulation by micromolar concentrations of H2O2 was inhibited by catalase, but also unexpectedly by SOD. Both VEGF and H2O2 increased S-glutathiolation of SERCA2b and increased Ca(2+) influx into EC, and these events could be blocked by overexpression of catalase or overexpression of SERCA2b in which the reactive cysteine-674 was mutated to a serine. In determining the source of VEGF-mediated ROS production, our studies show that specific knockdown of either Nox2 or Nox4 inhibited VEGF-induced S-glutathiolation of SERCA, Ca(2+) influx, and EC migration. Treatment with H2O2 induced S-glutathiolation of SERCA and EC Ca(2+) influx, overcoming the knockdown of Nox4, but not Nox2, and Amplex red measurements indicated that Nox4 is the source of H2O2. These results demonstrate that VEGF stimulates EC migration through increased S-glutathiolation of SERCA and Ca(2+) influx in a Nox4- and H2O2-dependent manner, requiring Nox2 downstream.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • NOX4-derived ROS can induce the reversible glutathionylation of SERCA and increase Ca2+ levels, thus regulating VEGF-signaling cell migration.

    “Consistent with this role of NOX4-derived ROS in angiogenesis (642, 989), it has been shown that NOX4 can modulate the role of VEGF-induced dimerization of CD146 necessary for cell adhesion (1065), and NOX4-derived ROS can induce the reversible glutathionylation of SERCA and increase Ca2+ levels, thus regulating VEGF-signaling cell migration (273).”

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.
