Figure 2

Concentration and time effects of degraded and undegraded carrageenan in FHs 74 Int cell line, as measured by the MTT assay. FHs 74 Int cells were treated with (A) FGKC, (B) DKC (C) CGKC (D) FGIC and (E) CGIC at concentrations of 62.5 – 2000.0 μg mL−1 and (F) tamoxifen at concentrations of 0.625- 20.000 μg mL−1 for 24 – 72 h. Degraded FGKC, DKC and CGKC showed IC50 in FHs 74 Int (black bold line). IC50 values were not found in degraded FGIC, CGIC and all undegraded carrageenan treated cells (black dotted line). Data are reported as means of three replicates from 3 independent experiments (n = 3). α: significant difference at 24 h; β: significant difference at 48 h and *: significant difference at 72 h for degraded carrageenan. Significant differences of undegraded carrageenan were in red symbols.
