Figure 1.
Regression models for the cytotoxic effects of all three mixture components in RKO (a), HCT-15 (b), and NCM460 (c) cells. The solid lines represent the regression models for acetate, butyrate, and propionate obtained in the SRB assay, following 48 h incubations. The labels are as follows: A—acetate, B—butyrate, P—propionate (for values see Table 2). Black dashed lines represent the upper and lower 95% CI for the regression fit. Experimental data were obtained from a minimum of three independent experiments run in triplicate.
