Nevertheless, due to the close relationship between O-GlcNAcylation processes and nutritional status (the donor of the GlcNAc group being UDP-GlcNAc positioned at the intersection of different metabolisms), it will be interesting to evaluate in the near future the activity of FASN in pathologies associated with nutritional disorders or for which increased OGT activity has been reported. This evidence concerns the gene FASN and nutritional disorder.
