Abstract

Axon degeneration is an active program of self-destruction observed in many physiological and pathological settings. There are three Nicotinamide mononucleotide adenylyl transferase (Nmnat, EC2.7.7.1) in mammals. Overexpression of Nmnat1 or Nmnat3 can delay axon degeneration, while the role of Nmnat2 in axon degeneration remains largely unknown. Here we found that Nmnat2 was specifically and highly expressed in brain compared with Nmnat1 and Nmnat3. Furthermore, we found brain Nmnat2 was correlated with Alzheimer's disease in APPswe/PS1dE9 transgenic mice. Nmnat2 delayed Wallerian degeneration in cultured superior cervical ganglia (SCGs) from morphological changes, microtubule destruction and neurofilament degradation, mutation of the conserved enzyme activity site in Nmnat2 disrupted its enzyme activity as well as the axon-protective function. Our results demonstrate that the brain-specific Nmnat2 delays injury-induced axon degeneration dependent on its NAD synthesis activity. These findings provide new clues to further study the molecular mechanisms of axon degeneration and the related neurodegenerative diseases.

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.
