Neferine Suppresses Experimental Colitis-Associated Colorectal Cancer by Inhibition of NF-κ B p65 and STAT3
Colitis is an important risk factor for the development of colorectal cancer (CRC). The inhibitory effect and the underlying mechanism of neferine on colitis-associated colorectal cancer (CA-CRC) were investigated using an azoxymethane (AOM)/dextran sulfate sodium (DSS) triggered mice model. Compared with the CA-CRC model, oral treatment of neferine (2.5 and 5.0 mg/kg) significantly inhibited the DAI scores, decreased the tumor number, and reduced the tumor size. Neferine decreased inflammatory cell infiltration and epithelial hyperplasia in colon tissues. The levels of tumor necrosis factor-α (TNF-α), interleukin-1beta (IL-1β), and interleukin 6 (IL-6) in colon tissues were decreased by neferine. Furthermore, neferine significantly decreased protein expressions of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), p-p65, and p-STAT3 in both tumor and non-tumor tissues. In addition, neferine inhibited LPS and IL-6-induced phosphorylation of both NF-κB p65 and STAT3. Molecular docking demonstrated the interactions of neferine with both NF-κB p65 and STAT3. In conclusion, these results suggested that neferine inhibited CA-CRC carcinogenesis possibly by regulating NF-κB and STAT3. Neferine might be a lead compound for the chemoprevention of CA-CRC.
