| abstractText | Studies showed that manipulation of gut microbiota (GM) composition through the treatment of prebiotics could be a novel preventive measure against colorectal cancer (CRC) development. In this study, for the first time, we assessed the non-toxic doses of the triterpene saponins (ginsenoside-Rb3 and ginsenoside-Rd) - as prebiotics - that effectively reinstated the dysbiotic-gut microbial composition and intestinal microenvironment in an Apc(Min/+) mice model. Rb3 and Rd effectively reduced the size and the number of the polyps that accompanied with the downregulation of oncogenic signaling molecules (iNOS, STAT3/pSTAT3, Src/pSrc). Both the compounds improved the gut epithelium by promoting goblet and Paneth cells population and reinstating the E-cadherin and N-Cadherin expression. Mucosal immunity remodeled with increased in anti-inflammatory cytokines and reduced in pro-inflammatory cytokines in treated mice. All these changes were correlating with the promoted growth of beneficial bacteria such as Bifidobacterium spp., Lactobacillus spp., Bacteroides acidifaciens, and Bacteroides xylanisolvens. Whereas, the abundance of cancer cachexia associated bacteria, such as Dysgonomonas spp. and Helicobacter spp., was profoundly lower in Rb3/Rd-treated mice. In conclusion, ginsenosides Rb3 and Rd exerted anti-cancer effects by holistically reinstating mucosal architecture, improving mucosal immunity, promoting beneficial bacteria, and down-regulating cancer-cachexia associated bacteria. |
