Figure 3From: Increase of cyclooxygenase-2 inhibition with celecoxib combined with 5-FU enhances tumor cell apoptosis and antitumor efficacy in a subcutaneous implantation tumor model of human colon cancerComparison of TUNEL positive rate in each group. The rate of tumor apoptosis in the control group, 5-FU group, celecoxib group and 5-FU + celecoxib group was 9.5%, 47.5%, 68.5% and 80.1%, respectively, P <0.05 among all groups.Back to article page
