PCa and 5-FU synergistically inhibited the growth of HT-29 cells in vitro. HT-29 cells were treated with (a) PCa (0, 10, 20, 40, or 80 μg/ml) and/or 5-FU (1.5 μg/ml), (b) 5-FU (0, 1 2, 4, or 8 μg/ml) and/or PCa (30 μg/ml) for 48 h, and then we measured cell viability by using an MTT assay. PCa and 5-FU revealed a synergistic effect (CI value < 1). Compared with PCa or 5-FU only vs. the combination group ().
