Therapeutic Mechanism and Effect of Camptothecin on Dextran Sodium Sulfate-Induced Ulcerative Colitis in Mice

Figure 4

Effects of camptothecin (CPT) on the MAPK signaling pathway in DSS-induced ulcerative colitis in mice. Tissue lysates were prepared and subjected to western blot using (a, b) p-ERK1/2, (a, c) p-JNK1/2, and (a, d) p-P38 antibodies. The p-ERK1/2, p-JNK1/2, and p-P38 immunoreactive bands were digitized and expressed as a ratio of ERK1/2, JNK1/2, and P38 levels (b–d). Values are presented as ( vs. the DSS group).
