ABSTRACT:

We investigated on colon cancer cells the effect of geraniol on thymidylate synthase and thymidine kinase expression, two enzymes related to 5-fluorouracil cytotoxicity. The anti-tumoral efficacy of geraniol and 5-fluorouracil were also evaluated on TC-118 human tumors transplanted in Swiss nu/nu mice. Geraniol (150 microM) but not 5-fluorouracil caused a 2-fold reduction of thymidylate synthase and thymidine kinase expression in cancer cells. In nude mice, the combined administration of 5-fluorouracil (20 mg/kg) and geraniol (150 mg/kg) caused a 53% reduction of the tumor volume, whereas a 26% reduction was obtained with geraniol alone, 5-fluorouracil alone showed no effect.
