A related animal experimental study [70] showed that the combination of total phenolic acid of Danshen stem leaves, the main component of Danshen injection, and tanshinone significantly improved the symptoms of ulcerative colitis in mice by inhibiting the TLR4/PI3K/AKT/mTOR signaling pathway and exerting a protective effect on the intestinal mucosa of mice with dextran sulfate sodium (DSS)-induced ulcerative colitis. The gene discussed is MTOR; the disease is ulcerative colitis.
