BMPs inhibit neurogenesis by a mechanism involving degradation of a transcription factor
Open accessAbstract
Bone morphogenetic proteins (BMPs), negative regulators of neural determination in the early embryo, were found to be potent inhibitors of neurogenesis in olfactory epithelium (OE) cultures. BMPs 2, 4 or 7 decreased the number of proliferating progenitor cells and blocked production of olfactory receptor neurons (ORNs). Experiments suggested that this effect was due to an action of BMPs on an early-stage progenitor in the ORN lineage. Further analysis revealed that progenitors exposed to BMPs rapidly (< 2 h) lost MASH1, a transcription factor known to be required for the production of ORNs. This disappearance was due to proteolysis of existing MASH1 protein, but new gene expression was required to trigger it. The data suggest a novel mechanism of BMP action, whereby the induced degradation of an essential transcription factor results in premature termination of a neuronal lineage.

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.
