Abstract

Backgrounds: Banxia Xiexin decoction (BXD) is widely used in the treatment of acute and chronic gastritis, peptic ulcer, dyspepsia, gastrointestinal dysfunction, chronic hepatitis, oral ulcer and other diseases, but there are few reports on its treatment of colon cancer. The current study was designed to investigate the effect of BXD on colon cancer and its possible molecular mechanisms.
Methods: Fifty SPF BALB/c nude mice were selected to establish an animal model of colon cancer bearing nude mice. Establishment of nude mice intestinal cancer model by subcutaneous injection of intestinal cancer cells. Serum superoxide dismutase (SOD) and malondialdehyde (MDA) were detected by commercial kits. Pro-inflammatory cytokines in serum were detected. Western blotting was used to demonstrate the expression levels of related apoptosis proteins, inflammation and oxidative stress proteins.
Results: Our results showed that BXD could decrease SOD and increased MDA in nude mice bearing tumors. BXD increased pro-inflammatory cytokines in serum in nude mice bearing tumors. Western blotting revealed that the protein expressions of Bax, Caspase-3, Caspase-9 were increased by different concentrations of BXD, while Bcl-2 was decreased. BXD also decreased Nrf-2 and HO-1, and increased the levels of MAPK/NF-κB pathway in tumor tissue.
Conclusions: BXD has an obvious tumor inhibiting effect on SW 480 colon cancer transplanted tumor in nude mice via apoptotic pathway and MAPK/NF-κB pathway.
