UGT8 and nasopharyngeal carcinoma: In summary, by the MS-based differential quantitative proteomics, we revealed that the dysfunction of Npc1 is not only associated with a reduced expression of various myelin structural and indispensable proteins (Bcas1, Enpp6, Mbp, and Ugt8) but also the proteins (Cers2, Ugt8, and Gltp) related to sphingolipid metabolism in NPC mice.
