Determining The Effects Of Maternal Adiposity On Preterm Neonatal Microbiome And Short Chain Fatty Acid Profiles, Dalton James, William A. Clark Phd, Kristy L. Thomas
Undergraduate Honors Theses
The gut microbiota and its metabolites have vast impacts on the human digestive system, immune system, and health outcomes. Short chain volatile fatty acids (SCVFAs) present in feces can be representative of the interactions of the microbiota present in the gut. Low microbiota diversity in the human gut is highly associated with obesity and adverse health outcomes. Furthermore, the maternal microbiome has a direct impact on neonatal microbiota through various pathways such as environment, skin flora, breast milk composition, and vaginal secretions. This study is aimed to further understand the associations between various factors (maternal adiposity, gestational time, length of …
Gut Microbial Metabolite Indole: A Stimulator Of Enteroendocrine Cell Differentiation Via Activation Of Aryl Hydrocarbon Receptor, James Hart
Theses, Dissertations and Capstones
Enteroendocrine cells (EECs) regulate energy balance and glucose homeostasis by releasing hormones in response to food intake. Dysregulated EEC differentiation is observed in obesity, while gut microbiota metabolites influence this process. Here, we investigated the role of indole, a biologically active gut microbial metabolite, in EEC differentiation through aryl hydrocarbon receptor (AhR) activation. Human intestinal organoids derived from jejunal mucosal biopsies were exposed to indole. Indole treatment significantly increased mRNA levels of chromogranin A, an EEC marker. The effect was reversed by an AhR antagonist, indicating AhR involvement. Indole also upregulated AhR target gene mRNA levels. These findings highlight the …
