Figure 15. Mice were injected intraperitoneally with a single dose (15 mg/kg) of AOM (the first week) followed by 3 times of 2% DSS given in the drinking water every two days (the second week). AS (150 and 300 mg/kg) was given oral administration every two days. Mice were sacrificed on 15 weeks after CAC induction and the expression of (A) p-NFκB, iNOS (B) VEGF and PCNA were analyzed using Western blotting.
