BAM-SiPc-PDT induced the expression of chemokines in CT26 cells. CT26 cells were treated with 8 nM BAM-SiPc and subjected to PDT. a After 8 h of incubation, total RNA was extracted from the cells and quantitative PCR was conducted to detect the level of various chemokines. b After 24 h of incubation, culture media were collected for cytokine concentration determination using ELISA kits. Data shown are means ± SEM of three independent experiments. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
