Evaluation of C-PC treatment effect on the COX-2 expression in the CT-26 cells by flow cytometry.

Groups	COX-2 negative %	COX-2 positive %
Control	7.2 ± 4.3%	92.8 ± 4.3%
RT	1.7 ± 1.1%	98.3 ± 1.1%
C-PC 50 µg/mL	11.8 ± 7.6%	88.2 ± 7.6%
C-PC 100 µg/mL	28.4 ± 6.1%	71.6 ± 6.1%
C-PC 200 µg/mL	74.8 ± 9.4%	25.2 ± 9.4%

Control: The cells which were not treated with C-PC (0 µg/mL), C-PC: C-phycocyanin., RT: radiation therapy.
