## Abstract

Fenugreek (Trigonella foenum-graecum) is used in many parts of the world for diabetes, cardiovascular
disease, and depression. While the mechanism(s) of these actions is not known, it is becoming increasingly
clear that gut microbiota are key players in homeostasis and also mediate true first-pass metabolism of dietary
compounds. Furthermore, the high protein and fiber content of fenugreek seeds is particularly suited to modify
intestinal bacteria and offset the dysbiotic effects of high fat/low fiber Western-style diets. Indeed, data from our
lab shows that fenugreek significantly alters intestinal microbial populations, and reverses key Western diet-
induced changes to gut microbiota. Based on these observations, we propose the following hypothesis:
 Fenugreek induces physiologic resiliency via changes to intestinal microbiota
Our hypothesis is based on the ability of fenugreek to offset diet-induced gut dysbiosis, and on data showing
that fenugreek-shaped microbiota can replicate selected effects of fenugreek. While these data support a role
for gut bacteria in beneficial responses to fenugreek, key data are needed to confirm and identify mechanisms
by which fenugreek-microbiota interactions drive physiologic benefits. First, the impact of gut microbiota on the
beneficial profile of fenugreek needs to be established. Further, whether fenugreek-microbiota interactions alter
the gut metabolome directly via unmasking/generation of otherwise-inaccessible botanical phytochemicals;
or indirectly via altered metabolism of Western diets should be resolved. Finally, identification of intestinal and
blood-based metabolites that mediate fenugreek-based physiologic resiliency is needed to accelerate the
translation of these findings. To meet these needs, we have devised a unique experimental approach
combining conventional and germ-free mice, an adaptive microbiome transplantation paradigm, and a series of
cutting-edge in silico analyses to identify microbiome-derived, fenugreek-based metabolites that drive
physiologic resiliency. Specific aim 1 conventionally-housed and germ-free mice to determine how intestinal
microbiota shape the beneficial effects of fenugreek. Aim 2 will use microbiome transplants to determine if
specific microbiota are both necessary and sufficient for the beneficial effects of fenugreek, and will determine
if fenugreek-microbiota interactions alter the gut metabolome directly via unmasking/generation of otherwise-
inaccessible botanical phytochemicals; or indirectly via altered metabolism of Western diets. Aim 3 will identify
the exact metabolites in blood and intestinal fractions that predict neurobehavioral and metabolic impairment
using validation cohorts and state-of-the art bioinformatic tools. Identification of these metabolites, and the
commensal bacteria responsible for their production, could spearhead the formulation of safe and effective
strategies to preserve health in the today's modern environment. Furthermore, impro...
