Th tea extract inhibited the expression of cell-cycle-related proteins. (A). HT-29 cells were treated with 0.2 mg/mL extract of different tea samples 03Y, 07Y, 11Y, 15Y and 19Y for 48 h, and then CDK2, CDK4 and CylinB1 expressions were detected by Western blotting. (B–D). Relative quantification of CDK2, CDK4 and CylinB1 protein levels in each group was shown, with actin as a reference. One-way ANOVA analysis was performed between the treatments of multiple tea samples. The different lowercase letters (a and b) in the same group show the significant differences at p < 0.05 level.
