Quantitative presentation of caspase 3 activity in HT 29 cells. The HT 29 colorectal cancer cells were treated with cisplatin or oxaliplatin with or without doxycycline and caspase 3 activity was measured. (Con = CON = Positive control, Dox = DOX = Doxycycline treatment for 24 hours, C1; C4; C24 = Cisplatin treatment for 1, 4 and 24 hours respectively, CD1; CD4; CD24 = Cisplatin and Doxycycline treatment for 1, 4 and 24 hours respectively, O1; O4; O24 = Oxaliplatin treatment for 1, 4 and 24 hours respectively, OD1; OD4; 0D24 = Oxaliplatin and Doxycycline treatment for 1, 4 and 24 hours respectively. *, **, *** – Statically significant difference). The data are depicted as means of three experiments ± standard deviation.
