FUT8 Regulates Cerebellar Neurogenesis and Development Through Maintaining the Level of Neural Cell Adhesion Molecule Cntn2.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Core fucosylation at N-glycans, which is uniquely catalyzed by fucosyltransferase FUT8, plays essential roles in post-translational regulation of protein function. Aberrant core fucosylation leads to neurological disorders in individuals with congenital glycosylation disorders (CDG). However, the underlying mechanisms for these neurological defects remain largely unknown. In this study, we have showed that FUT8 and fucosylation are abundant in cerebellum. Specific deletion of Fut8 in cerebellar granule neuron progenitors (GNPs) results in the impaired proliferation and differentiation of GNPs, as well as the compromised neuronal development, synaptic physiology and motor coordination. Mechanistically, we have showed that Fut8 deficiency reduced Contactin 2 (Cntn2) expression, a member of neural cell adhesion molecules (NCAMs). Furthermore, ectopic Cntn2 can rescue the neuronal defects induced by Fut8 deficiency. Collectively, our study has revealed the important roles of FUT8 and core fucosylation in regulating cerebellar development and function through modulating Cntn2 expression.
