D. Effect of detergent-resistant pellets prepared from Fn 12230 (Fn) and US1 (∆fadA) on tumor growth. HCT116 cells were inoculated into the nude mice as described above. In one group of mice (n=3), sarkosyl-resistant pellets prepared from Fn 12230 and US1 (∆fadA) were injected into the tumors on opposite sides. In another group (n=5), sarkosyl-resistant pellets prepared from Fn 12230 were mixed with OC or rabbit IgG control (rIgG) before injecting into the tumors on opposite sides. The tumor volumes were measured described above. The vertical lines represent the standard deviations. The individual tumor pairs are shown (right panel). *p < 0.05, **p < 0.01, ***p< 0.001 [compared to US1 (∆fadA), t-test].
