T. Fukuwatari et al., EXPRESSION OF THE PUTATIVE MEMBRANE FATTY-ACID TRANSPORTER (FAT) IN TASTE-BUDS OF THE CIRCUMVALLATE PAPILLAE IN RATS, FEBS letters, 414(2), 1997, pp. 461-464
The putative membrane fatty acid transporter (FAT) protein and its mRN
A, originally expressed in adipose tissue, were found in the tongue of
rats. Northern blot analysis showed a significant expression of FAT m
RNA in the epithelial layer of circumvallate papillae. Immunohistochem
ical staining revealed that immunoreactivity for FAT is specifically l
ocalized in the apical part of taste bud cells, possibly gustatory cel
ls, in the circumvallate papillae. (C) 1997 Federation of European Bio
