However, other astrocyte genes (Slc7a10, Myoc, Fam107a, Gjb6, Slc1a2, Aqp4, Aldh1a1, Slc2a4, S100b, Atp1a2), were not expressed by astroglia differentiated from NPC at in vivo astrocyte levels but were generally increased compared to NPC. This evidence concerns the gene MYOC and nasopharyngeal carcinoma.
