Dihydroartemisinin Protects against Dextran Sulfate Sodium-Induced Colitis in Mice through Inhibiting the PI3K/AKT and NF-κB Signaling Pathways

Figure 4

Dihydroartemisinin blocks activation of the PI3K/AKT signaling pathway in colitis both in vivo and in vitro. The mice were treated with DSS for 7 days and IEC-6 cells were treated with LPS for 24 hours, and then, the colon tissue and IEC-6 cell lysates were analyzed by western blotting. (a): Representative image of p-PI3K, PI3K, p-AKT, and AKT in colon tissues. (b): Quantification analysis of p-PI3K/PI3K and p-AKT/AKT in colon tissues. N = 4 in each group. vs. control group. vs. DSS group. (c) Representative image of p-PI3K, PI3K, p-AKT, and AKT in IEC-6 cells. (d) Quantification analysis of p-PI3K/PI3K and p-AKT/AKT in IEC-6 cells. N = 4 in each group. (e) Relative mRNA expression of TNF-α, IL-6, and IL-1β in IEC-6 cells. N = 4 in each group. vs. control group; vs. LPS group; and vs. LPS + DHA group.
