we utilized domain-specific probes and polyclonal antibodies against cea-related antigens to study sodium butyrate-induced expression of the cea gene family in a villous adenoma-derived cell line , which is nontumorigenic in nude mice ( vaco 235 ) , and two colonic carcinoma cell lines known to respond to sodium butyrate exposure by phenotypic differentiation ( ht-29 and ls 174t ) .
