Core Tip
Core Tip: The effect of the gut microbiome (GM) expands upon the intestine in altering the metabolism and inducing inflammation. Mutually, the host microenvironment impacts the GM through the variation of estrogen levels. The circulating estrogen itself is regulated through the β-glucuronidase enzyme which deconjugates estrogen to its biologically active form, allowing it to link to estrogen receptors and thus contributing to its physiological and pathological effects (e.g. cancers and specially sex-hormone driven cancers). In this review, the interaction between estrogen and microbiota in sex-hormone-mediated cancers as well as the potential health outcomes on their clinical management are emphasized.
