Abstract
High fecal deoxycholate levels may promote colonic cancer. Phospholipids protect against bile salt-induced cytotoxicity. We therefore aimed to examine whether the dietary phospholipid sphingomyelin could decrease hyperproliferation induced by deoxycholate. In CaCo2 cells, hyperproliferation (by bromodeoxyuridine assay), phosphorylation state of cellular proteins, and apoptosis with concomitant caspase-3 activity were evaluated after incubation with 50–500 μM deoxycholate, with or without sphingomyelin. At 2 and 4 hr of incubation, deoxycholate induced dose-dependent apoptosis, with concomitant caspase-3 activation. At 16 hr, apoptosis had decreased markedly, but there was dose-dependent hyperproliferation (with changed phosphorylation status of cellular proteins) at this time point. Sphingomyelin dose-dependently reduced deoxycholate-induced apoptosis and hyperproliferation. In conclusion, sphingomyelin reduces deoxycholate-induced hyperproliferation and apoptosis. These findings may have implications for colonic cancer prevention by dietary modification.
