Fatty acids are a major source of energy for cardiac myocytes. Changes in fatty acid metabolism have been implicated as causal in diabetes and cardiac disease. The mechanism by which long chain fatty acids (LCFAs) enter cardiac myocytes is not well understood but appears to occur predominantly by protein-mediated transport. Here we report the cloning, expression pattern, and subcellular localization of a novel member of the fatty acid transport protein (FATP) family termed FATP6. FATP6 is principally expressed in the heart where it is the predominant FATP family member. Similar to other FATPs, transient and stable transfection of FATP6 into 293 cells enhanced uptake of LCFAs. FATP6 mRNA was localized to cardiac myocytes by in situ hybridization. Immunofluorescence microscopy of FATP6 in monkey and murine hearts revealed that the protein is exclusively located on the sarcolemma. FATP6 was restricted in its distribution to areas of the plasma membrane juxtaposed with small blood vessels. In these membrane domains FATP6 also colocalizes with another molecule involved in LCFA uptake, CD36. These findings suggest that FATP6 is involved in heart LCFA uptake, in which it may play a role in the pathogenesis of lipid-related cardiac disorders. << Less

The blood-brain barrier (BBB), formed by the brain capillary endothelial cells, provides a protective barrier between the systemic blood and the extracellular environment of the CNS. Passage of fatty acids from the blood to the brain may occur either by diffusion or by proteins that facilitate their transport. Currently several protein families have been implicated in fatty acid transport. The focus of the present study was to identify the fatty acid transport proteins (FATPs) expressed in the brain microvessel endothelial cells and characterize their involvement in fatty acid transport across an in vitro BBB model. The major fatty acid transport proteins expressed in human brain microvessel endothelial cells (HBMEC), mouse capillaries and human grey matter were FATP-1, -4 and fatty acid binding protein 5 and fatty acid translocase/CD36. The passage of various radiolabeled fatty acids across confluent HBMEC monolayers was examined over a 30-min period in the presence of fatty acid free albumin in a 1 : 1 molar ratio. The apical to basolateral permeability of radiolabeled fatty acids was dependent upon both saturation and chain length of the fatty acid. Knockdown of various fatty acid transport proteins using siRNA significantly decreased radiolabeled fatty acid transport across the HBMEC monolayer. Our findings indicate that FATP-1 and FATP-4 are the predominant fatty acid transport proteins expressed in the BBB based on human and mouse expression studies. While transport studies in HBMEC monolayers support their involvement in fatty acid permeability, fatty acid translocase/CD36 also appears to play a prominent role in transport of fatty acids across HBMEC. << Less
