Mapping human microbiome drug metabolism by gut bacteria and their genes | Nature

Individuals vary widely in their responses to medicinal drugs, which can be dangerous and expensive owing to treatment delays and adverse effects. Although increasing evidence implicates the gut microbiome in this variability, the molecular mechanisms involved remain largely unknown. Here we show, by measuring the ability of 76 human gut bacteria from diverse clades to metabolize 271 orally administered drugs, that many drugs are chemically modified by microorganisms.

Gut bacteria may be linked to high blood pressure and depression -- ScienceDaily

The researchers isolated DNA (deoxyribonucleic acid, the carrier of genetic information) from gut bacteria obtained from the stool samples of 105 volunteers. They used a new technique involving artificial-intelligence software to analyze the bacteria, which revealed four distinct types of bacterial genes and signature molecules. Surprisingly, the investigators discovered unique patterns of bacteria from people with 1) high blood pressure plus depression; 2) high blood pressure without depression; 3) depression with healthy blood pressure; or 4) healthy subjects without depression or high blood pressure.

N-of-1 Clinical Trials: Removing the Hay to Find the Needle | Clinical Chemistry

an observed lack of universality in response to interventions and a greater focus on the individual with the emergence of precision medicine. A strong focus on the uniqueness of each individual has led to many discoveries in cancer diagnostics and drug efficacy and has prompted the US Food and Drug Administration to relabel numerous approved drugs to include pharmacogenomics information.
