Quercetin-Induced Cell Death in Human Papillary Thyroid Cancer (B-CPAP) Cells

Figure 6

Determination of proteasome activity after quercetin treatment of B-CPAP cells. The fluorogenic peptide suc-LLVY-MCA was used as substrate to measure chymotrypsin-like (CT-L) activities of 20S and 26S proteasome. Differences between means and significance of the treatments were analyzed using ANOVA and Bonferroni posttest. Bar graphs represent mean ± SD, . versus control, versus control.
