Study Title | Impact of early-life exposure to a potent aryl hydrocarbon receptor ligand on gut microbiota and host glucose homeostasis in C57BL/6J male mice (Part II) |
Study Summary | This study aimed to explore the association between early-life exposure to a potent aryl hydrocarbon receptor (AHR) agonist and persistent disruptions in the microbiota, leading to impaired metabolic homeostasis later in life. This study utilized metagenomics, NMR- and mass spectrometry-based metabolomics, and biochemical assays to analyze the gut microbiome composition and function, as well as the physiological and metabolic effects of early-life exposure to 2,3,7,8-tetrachlorodibenzofuran (TCDF) in conventional, germ-free (GF), and Ahr-null mice. The impact of TCDF on Akkermansia muciniphila (A. muciniphila) in vitro was assessed using optical density (OD 600), flow cytometry, transcriptomics, and mass spectrometry-based metabolomics. TCDF-exposed mice exhibited disruption in the gut microbiome community structure and function, characterized by lower abundances of A. muciniphila, lower levels of cecal short chain fatty acids (SCFAs) and indole-3-lactic acid (ILA), and a reduction in gut hormones GLP-1 and PYY. Importantly, microbial and metabolic phenotypes associated with early-life POP exposure were transferable to GF recipients in the absence of POP carry-over. In addition, AHR-independent interactions between POPs and the microbiota were observed, significantly affected the growth, physiology, gene expression, and metabolic activity of A. muciniphila, resulting in suppressed activity along the ILA pathway. |

MS Type: | EI |
MS Comments: | For ionization, the EI source was used with the following settings: filament source temperature at 230 °C and electron ionization energy at 70 eV. Mass spectra were collected in a mass range of m/z 50 - 600 at a scan rate of 2 spectra/s. Mass calibration was performed after every injection with internal reference masses m/z 68.9947, 263.9866 and 501.9706. Data acquisition was performed using the Agilent MassHunter Workstation GC-MS Data Acquisition v 10.0 (Agilent Technologies, Waldbronn, Germany). |
