[HTML][HTML] Identification of a goblet cell-specific enhancer element in the rat intestinal trefoil factor gene promoter bound by a goblet cell nuclear protein

H Ogata, N Inoue, DK Podolsky - Journal of Biological Chemistry, 1998 - ASBMB
Intestinal trefoil factor (ITF) is selectively expressed in goblet cells of the small and large
intestinal mucosa. Detailed analysis of the rat ITF (RITF) promoter was undertaken by
transient transfection and gel mobility shift assays (GMSAs) using the goblet cell-like
LS174T colon cancer-derived cell line. Various lengths of wild-type or mutant constructs of
the 5′-flanking region were linked to the pXP2 reporter gene luciferase. Expression of− 118
RITF was significantly decreased compared with− 154 RITF, and transfection with an 18 …
