Fig. 1From: The role of GLI1 for 5-Fu resistance in colorectal cancerCharacterization of 5-FU resistant LoVo-R cells. a Shows morphology of LoVo and LoVo-R cells. b Shows the IC50 dose of 5-FU calculated from measurement of cell viability in different concentrations of 5-FU (48 h). The X-axis is 5-FU concentration (μg/ml), and the Y-axis is O.D. values. Significant difference was indicated by *p < 0.05, **p < 0.005, or ***p < 0.0005Back to article page
