Barley leaf (BL) is potentially beneficial to intestinal health.But the impact on colorectal cancer (CRC) is unclear.To investigate the impact and mechanism, this study established two mouse models of CRC induced by azoxymethane (AOM) /dextran sodium sulfate (DSS) and CT26 subcutaneous injection.Results showed that BL could significantly reduce the AOM/DSS-induced tumorigenesis and had no impacts on transplanted tumor growth.Meanwhile, by means of western blot, 16S analysis, and gas chromatography-mass spectrometer (GC-MS) analysis, this study found that 5% BL significantly decreased the expression of cyclooxygenase-2 (COX-2) and epidermal growth factor receptor (EGFR) in the colon, improved dysbacteriosis, and increased the concentration of short-chain fatty acid (SCFA).Cell experiments showed that the sodium salt of SCFA could restrain the malignant transformation of epithelial cells by reducing the expression of p-AKT and p-ERK.In summary, barely leaf could attenuate the AOM/DSS-induced tumorigenesis via dysbacteriosis amelioration, increasing the concentration of part SCFA and down-regulating the expression of key proteins in tumor-related signaling pathways.
