Abstract

Carbon monoxide (CO), previously considered a toxic waste product of heme catabolism, is emerging as an important gaseous molecule. In addition to its important role in neurotransmission, exogenous CO protects against vascular injury, transplant rejection, and acute lung injury. However, little is known regarding the precise signaling mechanisms of CO. We have recently shown that CO attenuates endothelial cell apoptosis during anoxia-reoxygenation injury by activating MKK3/p38alpha mitogen-activated protein kinase (MAPK) pathways. Our current study is the first to demonstrate that CO can differentially modulate STAT1 and STAT3 activation and, specifically, that STAT3 activation by CO is responsible for the anti-apoptotic effect in endothelial cells. In addition, we show that the anti-apoptotic effects of CO depend upon both phosphatidylinositol 3-kinase/Akt and p38 MAPK signaling pathways in endothelial cells, whereas previous reports have implicated only the MKK3/p38 MAPK pathway. Using chemical inhibitors and dominant negative constructs, we show that CO enhances STAT3 activation via phosphatidylinositol 3-kinase/Akt and p38 MAPK pathways with subsequent attenuation of Fas expression and caspase 3 activity. These data highlight the anti-apoptotic signaling mechanisms of CO and, importantly, delineate potential therapeutic strategies to prevent ischemia-reperfusion or anoxia-reoxygenation injury in the vasculature.

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.
