Fatty acids inhibit anticancer effects of 5-fluorouracil in mouse cancer cell lines.

ABSTRACT: The present study investigated the effects of two major dietary fatty acid components, linoleic acid (LA) and elaidic acid (EA), on the antitumor effects of 5-fluorouracil (5-FU) in the LL2, CT26 and CMT93 mouse cancer cell lines. Concurrent treatment with LA and 5-FU elicited a decreased cell viability compared with treatment with 5-FU alone. In addition, increased inhibition of growth was observed following concurrent treatment with EA and 5-FU. Sequential treatment of LA followed by 5-FU abrogated the anticancer effects of 5-FU, and treatment with EA followed by 5-FU increased cancer cell growth in addition to abrogating the anticancer effects of 5-FU. The expression of the stem cell markers CD133 and nucleostemin (NS) increased in all three cell lines treated concurrently with 5-FU and
