Synergistic Antitumor Effect of Dichloroacetate in Combination with 5-Fluorouracil in Colorectal Cancer
Figure 2
Mean values of the combination index at the affected fractions of 50% (IC50) and 80% (IC80) when 5-fluoruracil (5-FU) was combined with dichloroacetate (DCA) in HT-29, LoVo, LS174t, and SW620 cells. Mean IC50 and IC80 ± SD () are shown. A CI value significantly less than 1 indicates synergism, a CI not significantly different from 1 indicates addition, and a CI significantly higher than 1 indicates antagonism; *.
