Gut Bacteria Can Control Organ Functions

Bacteria in your gut may be doing more than helping to digest food -- it could also be exerting some level of control over the metabolic functions of your other organs.

Researchers exposed germ-free mice to bedding that had previously been used by conventional mice with normal gut bacteria.  The new bacteria triggered a number of processes in their livers. Statistical modeling determined that the levels of glucose, glycogen and triglycerides in the liver were strongly associated with a single family of bacteria called Coriobacteriaceae.

Eurekalert reports:

“Another important finding in the paper ... is that gut colonization strongly stimulated the expression and activity of the cytochrome P450 3A11, an essential enzyme in drug-detoxification pathways.”
