Intestinal expression of multidrug resistance-associated protein 2 (Mrp2), monocarboxylate transporter 1 (Mct1), and UDP-glucuronosyltransferase (Ugt) and liver expression of Cyp51a1 and Cyp2c29 have been found altered in AD transgenic models [102]. This evidence concerns the gene SLC16A1 and Alzheimer disease.
