The effect of CL on the apoptosis regulation. (A) Immunocytochemistry morphology of Bcl-2 expression; (B) quantification of Bcl-2 expression; and (C) percentage of Rac-1 gene expression level of cell migration-related proteins was measured by quantitative real-time polymerase chain reaction. Data are presented as mean + SEM, N = 3. *P < 0.05 Indicates significant differences in comparison with the untreated cells. CL, Curcuma longa; Bcl-2, B-cell lymphoma 2; Rac-1, Ras-related C3 botulinum toxin substrate 1.
