Fecal proteomics as a novel method to study mammalian behavior and physiology

Project description:Mammalian feces can be collected non-invasively during field research and provides valuable information on the ecology and evolution of the host individuals. Undigested food objects, genome/metagenome, steroid hormones, and stable isotopes obtained from fecal samples provide evidence on diet, host/symbiont genetics, and physiological status of the individuals. However, proteins in mammalian feces have hardly been studied, which hampers the molecular investigations into the behavior and physiology of the host individuals. Here, we apply mass spectrometry-based proteomics to fecal samples (n = 10) that were collected from infant, juvenile, and adult captive Japanese macaques (Macaca fuscata) to describe the proteomes of the host, food, and intestinal microbes. The results show that fecal proteomics is a useful method to investigate dietary changes along with breastfeeding and weaning, to reveal the organ/tissue and taxonomy of dietary items, and to estimate physiological status inside intestinal tracts. These types of insights are difficult or impossible to obtain through other molecular approaches. Most mammalian species are facing extinction risk and there is an urgent need to obtain knowledge on their ecology and evolution for better conservation strategy. The fecal proteomics framework we present here is easily applicable to wild settings and other mammalian species, and provides direct evidence of their behavior and physiology.

RNA transcriptomics of healthy and PI-IBS colonic biopsies

Project description:A subset of post-infection irritable bowel syndrome (PI-IBS) patients have elevated, or high fecal proteolytic activity (PA). Fecal PA has been shown to correlate with increased symptom severity as well as lower quality of life scores, increased fecal output and increased intestinal permeability. To address the underlying mechanisms of barrier disruption as a consequence of high fecal PA, colonic biopsies were collected from healthy individuals PI-IBS patients (n=11). Individuals diagnosed with PI-IBS were further divided in to 2 subgroups, high PA and low PA as defined by the PA in matched fecal samples. RNA was extracted from the biopsies for bulk RNA sequencing to understand transcriptional differences between healthy and high PA PI-IBS patients as well as high PA and Low PA PI-IBS patients.

Diurnal rhythmicity of fecal microbiota and metabolite profiles in the first year of life: a randomized controlled interventional trial with infant formula

Project description:Microbiota assembly in the infant gut is influenced by time and duration of dietary exposure to breast-milk, infant formula and solid foods. In this randomized controlled intervention study, longitudinal sampling of infant stools (n=998) showed similar development of fecal bacterial communities between formula- and breast-fed infants during the first year of life (N=210). Infant formula supplemented with galacto-oligosaccharides (GOS) was most efficient to sustain high levels of bifidobacteria compared to formula containing B. longum and B. breve or placebo. Metabolite (untargeted) and bacterial profiling (16S rRNA/shallow metagenomics sequencing) revealed 24-hour oscillations and integrated data analysis identified circadian networks. Rhythmicity in bacterial diversity, specific taxa and functional pathways increased with age and was most pronounced following breast-feeding and GOS-supplementation. Circadian rhythms in dominant taxa were discovered ex-vivo in a chemostat model. Hence microbiota rhythmicity develops early in life, likely due to bacterial intrinsic clock mechanism and is affected by diet.
