Akt Signals through the Mammalian Target of Rapamycin Pathway to Regulate CNS Myelination
Open accessAbstract
Mammalian target of rapamycin (mTOR), a well known Akt substrate, regulates multiple cellular functions including cell growth and protein synthesis. The current study identifies a novel role of the Akt/mTOR pathway as a regulator of CNS myelination. Previously, we showed that overexpressing constitutively active Akt in oligodendrocytes in a transgenic mouse model induces enhanced CNS myelination, with no changes in the proliferation or survival of oligodendrocyte progenitor or mature cells. The present study focused on the signaling mechanisms regulating this hypermyelination induced by Akt. Activation of mTOR and its downstream substrates (p70S6 kinase and S6 ribosomal protein) was observed in Akt-overexpressing oligodendrocytes. When mTOR signaling was inhibited chronically in vivo with rapamycin starting at 6 weeks of age, the observed hypermyelination was reduced to approximately the amount of myelin seen in wild-type mice. mTOR inhibition had little impact on wild-type myelination between 6 and 12 weeks of age, suggesting that, in normal adults, myelination is relatively complete and is no longer regulated by mTOR signaling. However, when mTOR was chronically inhibited in young adult wild-type mice, myelination was reduced. These results suggest that, during active myelination, the major Akt signal regulating CNS myelination is the mTOR pathway.

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.
