RhoA triggers a specific signaling pathway that generates transforming microvesicles in cancer cells
Open accessAbstract
Vesicular structures called microvesicles (MVs) that are shed from the surfaces of cancer cells are capable of transferring oncogenic cargo to recipient cancer cells, as well as to normal cells, sending mitogenic signals that greatly enhance tumor growth. Because MVs are stable in the circulation, they also may have a key role in secondary colonization and metastasis. Thus, understanding how MVs are generated could have important consequences for interfering with cancer progression. Here we report that the small GTPase RhoA triggers a specific signaling pathway essential for MV biogenesis in various human cancer cells. Inhibiting the activity of different proteins comprising this pathway blocks MV biogenesis in the donor cancer cells and prevents oncogenic transformation in cell culture as well as tumor growth in mice. Although RhoA has often been implicated in human cancer, these findings now highlight a previously unappreciated role for this GTPase in malignant transformation, and demonstrate that blocking MV biogenesis may offer novel approaches for interfering with malignant transformation.

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.
