Gut-liver axis-mediated mechanism of liver cancer: a special focus on the role of gut microbiota.

Cancer Sci 2021 Sep 17. Epub 2021 Sep 17.

Research Institute for Microbial Diseases, Osaka University, Suita, Osaka, Japan.

Gut microbiota and the mammalian host share a symbiotic relationship, where the host provides a suitable ecosystem for the gut bacteria to digest indigestible nutrients and produce useful metabolites. While gut microbiota primarily reside in and influence the intestine, they also regulate liver function via absorption and subsequent transfer of microbial components and metabolites through the portal vein to the liver. Owing to this transfer, the liver may be continuously exposed to gut-derived metabolites and components. Read More
