ANOVA results indicated significant seasonal differences for 19 different carbon substrates including 3 amino acids (L-phenylalanine, L-serine, and glycyl-L-glutamic acid), 9 carbohydrates ([alpha]-D-lactose, [beta]-methyl D-glucoside, D-cellobiose, D-mannitol, i-erythritol, glucose-1-phosphate, D-galacturonic acid [gamma]-lactone, N-acetyl-D-glucosamine, and D-xylose), 4 carboxylic acids ([alpha]-ketobutyric acid, [gamma]-hydroxybutyric acid, pyruvic acid methyl ester, and D-galacturonic acid), 2 polymers ([alpha]-cyclodextrin and 2-hydroxybenzoic acid), and 1 phenolic compound (2-hydroxybenzoic acid).

MCT4 has been observed in lactate-producing tissues, specifically in skeletal muscle and astrocytes, and displays a lower affinity for substrates such as L-lactic acid and pyruvic acid. Recently, MCT4 has been shown to localize to the membrane of glial cells in the cerebellum [14] and the paraventricular nucleus, specifically in astrocytes and ciliated ependymal cells, playing a significant nonmetabolic role in the neuroprotective mechanism of ischemic preconditioning (IPC) in the gerbil with transient cerebral ischemia [28].
