Fig. 3From: Effects of different extracts of curcumin on TPC1 papillary thyroid cancer cell lineEffects of three different extracts of Curcuma, Arjuna®, Naturex®, C3Complex® on a papillary thyroid carcinoma cell line (TPC1), treated with 25 μM for 24 h (a) and 48 h (b). After incubation, the effects of curcumin on cell viability were determined by MTT assay. The optical density of the cell suspension was measured at 570 nm using a microplate reader, and from the analysis it was obtained the histogram. All data represent as the means ± SEM of three independent experiments. P < 0.01**, P < 0.001*** vs. the control (untreated cells) (ANOVA)Back to article page
