Colorectal cancer (CRC) is a common malignant tumor that occurs in the colon. Gut microbiota is a complex ecosystem that plays an important role in the pathogenesis of CRC. Our previous studies showed that the soluble dietary fiber of foxtail millet (FMB-SDF) exhibited significant antitumor activity in vitro. The present study evaluated the anticancer potential of FMB-SDF in the azoxymethane (AOM)- and dextran sodium sulfate (DSS)-induced mouse CRC models. The results showed that FMB-SDF could significantly alleviate colon cancer symptoms in mice. Further, we found that FMB-SDF consumption significantly altered gut microbiota diversity and the overall structure and regulated the abundance of some microorganisms in CRC mice. Meanwhile, KEGG pathway enrichment showed that FMB-SDF can also alleviate the occurrence of colon cancer in mice by regulating certain cancer-related signaling pathways. In conclusion, our findings may provide a novel approach for the prevention and biotherapy of CRC.
结直肠癌(CRC)是一种常见于结肠的恶性肿瘤。肠道微生物群是一个复杂的生态系统,在CRC的发病机制中起重要作用。我们之前的研究表明,谷子可溶性膳食纤维(FMB-SDF)在体外具有显著的抗肿瘤活性。本研究评估了FMB-SDF在氧化偶氮甲烷(AOM)和葡聚糖硫酸钠(DSS)诱导的小鼠CRC模型中的抗癌潜力。结果表明,FMB-SDF可显著减轻小鼠结肠癌症状。此外,我们发现食用FMB-SDF可显著改变CRC小鼠肠道微生物群的多样性和整体结构,并调节某些微生物的丰度。同时,KEGG通路富集表明,FMB-SDF还可通过调节某些癌症相关信号通路减轻小鼠结肠癌的发生。总之,我们的研究结果可能为CRC的预防和生物治疗提供一种新方法。
