In vivo activation of JAK2/STAT‐3 pathway during angiogenesis induced by GM‐CSF
Abstract
Besides the regulation of hematopoiesis, granulocyte‐macrophage colony‐stimulating factor (GM‐CSF) induces the expression of a functional program in cultured endothelial cells (ECs) related to angiogenesis and to the their survival in bone marrow microenvironment. ECs express the specific GM‐CSF receptor that signals through the recruitment and the activation of Janus kinase (JAK)2 (Soldi et al., Blood 89 , 863–872, 1987). We now report that GM‐CSF in vivo induces angiogenesis and activates JAK‐2 and signal transducers and activators of transcription (STAT)‐3. This cytokine has an angiogenetic activity in chick chorioallantoic membrane (CAM) without recruitment of inflammatory cells and induces vessel sprouting from chicken aorta rings. When added to CAM, subnanomolar concentrations of GM‐CSF cause a rapid phosphorylation in tyrosine residues of JAK‐2 persisting at least for 10 min. Furthermore, we show that signal transducers and activators of transcription (STAT)‐3, but not STAT‐5, also are phosphorylated for 30 min after GM‐CSF stimulation. AG‐490, a JAK‐2 inhibitor, reduced in a dose‐dependent manner the angiogenic effect of GM‐CSF in CAM. These findings provide the first evidence that the JAK‐2/STAT‐3 pathway is activated in vivo and participates in vessel formation triggered by GM‐CSF.

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.
