T1734 PDX1 Overexpression in Human Intestinal Epithelial Caco-2 Cells Represses Growth and Alters Expression of Genes Associated with Cell Proliferation

both long and short chains as well by cleaving alpha-1,6 linkages and is the only subunit with this activity.A combination of four subunits reached highest glucogenesis indicating a broader spectrum of glucosidase activities than any individual subunit alone.Some alpha-LDx was not completely available for enzyme hydrolysis, and residues are considered either slowly digestible or resistant to human enzyme digestion.This study for the first time shows the direct role of individual mucosal glucosidase subunits in starch digestion and reveals the potential of producing slow glucose release dextrins.
