In other cell types, including astrocytes, melanoma cells, and endothelial cells, particularly those of the blood-retinal, blood-brain, and cerebrospinal fluid-blood barriers, DHA’s transport by GLUT1 is possible by the local and transient oxidation of AA and is relevant to maintain cerebral vitamin C levels [6,9,10]. The gene discussed is SLC2A1; the disease is melanoma.
