Abstract

The TGF-β pathway plays an important role in physiological and pathological angiogenesis. MicroRNAs (miRNAs) are a class of 18- to 25-nucleotide, small, noncoding RNAs that function by regulating gene expression. A number of miRNAs have been found to be regulated by the TGF-β pathway. However, the role of endothelial miRNAs in the TGF-β-mediated control of angiogenesis is still largely unknown. Here we investigated the regulation of endothelial microRNA-29a (miR-29a) by TGF-β signaling and the potential role of miR-29a in angiogenesis. MiR-29a was directly up-regulated by TGF-β/Smad4 signaling in human and mice endothelial cells. In a chick chorioallantoic membrane assay, miR-29a overexpression promoted the formation of new blood vessels, and miR-29a suppression completely blocked TGF-β1-stimulated angiogenesis. Consistently, miR-29a overexpression increased tube formation and migration in endothelial cultures. Mechanistically, miR-29a directly targeted the phosphatase and tensin homolog (PTEN) in endothelial cells, leading to activation of the AKT pathway. PTEN knockdown recapitulated the role of miR-29a in endothelial migration, whereas AKT inhibition completely attenuated the stimulating role of miR-29a in angiogenesis. Taken together, these results reveal a crucial role of a TGF-β-regulated miRNA in promoting angiogenesis by targeting PTEN to stimulate AKT activity.

    From GDF10 is a signal for axonal sprouting and functional recovery after stroke (2015) · cites this paper as [31]

    The Discussion reports that TGF-β signaling promotes angiogenesis by up-regulating miR-29a in endothelial cells. The paper does not address astrocyte responses or neuroinflammation (searched: astrocyte responses, neuroinflammation, brain inflammation), so it supports only the angiogenesis part of the sentence.

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.
