Matrine may be protective against colorectal cancer (CRC), but how it may work is unclear. Thus, we explored the underlying\nmechanisms of matrine in CRC. Matrine-related proteins and CRC-related genes and therapeutic targets of matrine in CRC\nwere predicted using a network pharmacology approach. Five targets, including interleukin 6 (IL-6), the 26S proteasome, tumor\nnecrosis factor alpha (TNF-�±), transforming growth factor beta 1 (TGF-�²1) and p53, and corresponding high-mobility group\nbox 1 (HMGB1) signaling and T helper cell differentiation were thought to be associated with matrineâ��s mechanism. Expression\nof predicted serum targets were verified in a 1,2-dimethylhydrazine dihydrochloride-induced CRC model rats that were treated\nwith matrine (ip) for 18 weeks. Data show that matrine suppressed CRC growth and decreased previously elevated expression of\nIL-6, TNF-�±, p53, and HMGB1. Matrine may have had a therapeutic effect on CRC via inhibition of HMGB1 signaling, and this\noccurred through downregulation of IL-6, TNF-�±, and HMGB1.
