Description and Significance

Roseburia intestinalis is a major inhabitant of the human gut microbiome, making up 2.3% of the entire gut microbiome and up to 20% of the bacteria found in the colorectal region (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8647967/). R. intestinalis is a butyrate producer, a short-chain fatty acid that provides an energy source for colon epithelial cells to break down dietary fiber. The main reason for it’s ability to produce butyrate is from the enzyme Butyryl-CoA:acetate CoA transferase, which can transform acetate into butyrate. Butyrate is also known to suppress colon cancer, as it induces histone acetylation on the epithelial cells. (https://ncbi.nlm.nih.gov/pmc/articles/PMC9396028/) Butyrate in healthy colon cells will feed them through beta-oxidation, which is what most healthy epithelial cells prefer. It acts as a natural histone deacetylase enzyme inhibitor, which are enzymes known to lead to oncogene expression and is a factor that leads to colon cancer. As R. intestinalis acts as a natural inhibitor to these HDACs, cancer therapies involving R. intestinalis is on the rise in research. Lack of butyrate production has been associated with diseases such as inflammatory bowel disease and Type 2 diabetes. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8647967/) Live Biotherapeutics Drug Discovery has announced R. intestinalis and the rest of its genus as a Next Generation Probiotic for people with digestive issues to restore their gut health, as butyrate production is a big reason inflammation can be suppressed in the gut.
