Glucose uptake by rabbit intestine has been shown to be confined to the upper two-thirds of jejunal villi. Inhibition by phloridzin shows most of this transport to take place through the Na(+)-glucose linked transporter (SGLT1). Parallel measurements on the other hand show SGLT1 mRNA expression to increase rapidly as enterocytes reach the crypt-villus junction. Levels of SGLT1 mRNA then remain elevated in all villus enterocytes. These results provide direct evidence that SGLT1-mediated glucose transport is subject to post-transcriptional control.
