All were taking a full diet supplying approximately 1 gm. of tryptophan per day. The control subjects were drawn from laboratory personnel and middle-aged persons undergoing periodic health ...
And the result “identified alterations in tryptophan metabolism, and specifically indole, that correlated with disease.” “We found that when indole is present, the mice start to develop ...
By further exploring the underlying mechanism of SIN-mediated gut microbiota regulation, the team found that tryptophan metabolites (indole-3-acrylic acid, indole-3-propionic acid, and indole-3 ...
The research highlights the complex role of tryptophan metabolism in cancer. While tryptophan is known to be metabolized into ...
It is also clear that this derangement in tryptophan metabolism is not specific for one disease since increased urinary indole-3-acetic acid is found in patients with tropical sprue, nontropical ...
New research shows how metabolic activity and thus the communication between intestinal tissue and microbiome collapses during intestinal inflammation.
This cycle impacts many other functions, including the metabolism of nutrients and your immune system (23). Several studies have shown that increasing tryptophan in the diet can improve sleep by ...
Prenatal phthalate levels in the mother's blood during pregnancy were associated with lower levels of key neurotransmitter precursors (related to tyrosine and tryptophan metabolism) important for ...
