Study IDST001872
Study TitleUntargeted LC-MS metabolomics analysis of cecal content of mice treated with TCDD vs. vehicle control (part II)
Study TypeUntargeted metabolomics
Study SummarySix-week-old female wildtype (WT) C57BL/6 mice were administered a single 100µl intraperitoneal injection containing sterile corn oil (VEH group) or an intraperitoneal injection of 10µg/kg TCDD suspended within sterile corn oil (TCDD group). At the 72h time point following TCDD or VEH exposure, the mice were humanely euthanized by an overdose of inhaled isoflurane. During necropsy, cecal content and blood serum samples were collected for untargeted metabolomics profiling.

Project Title:Effects of Acute 2,3,7,8-Tetrachlorodibenzo-p-dioxin Exposure on the Circulating and Cecal Metabolome Profile
Project Type:Untargeted metabolomics
Project Summary:2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a polyhalogenated planar hydrocarbon belonging to a group of highly toxic and persistent environmental contaminants known as “dioxins”. TCDD is an animal teratogen and carcinogen that is well characterized for causing immunosuppression through activation of Aryl Hydrocarbon Receptor (AHR). In the current study, we investigated the effect of exposure of mice to an acute dose of TCDD on the metabolic profile within the serum and cecal contents to better define the effects of TCDD on host physiology. Our findings demonstrated that within the circulating metabolome following acute TCDD, there was significant dysregulation in the metabolism of bioactive lipids, amino acids, and carbohydrates when compared to the VEH treated mice. These wide-spread changes in metabolite abundance were identified to regulate host immunity via modulating Nuclear Factor-Kappa B (NF-κB) and Extracellular Signal‑Regulated Protein Kinase (ERK1/2) activity, and work as biomarkers for a variety of organ injuries and dysfunctions that follow TCDD exposure. Within the cecal content, of mice exposed to TCDD, we were able to detect changes in inflammatory markers that regulate NF-κB, markers of injury-related inflammation, and changes in lysine degradation, nicotinamide metabolism, and butanoate metabolism, which suggested an immediate suppression microbial metabolism. Collectively, these results demonstrate that acute TCDD exposure results in immediate irregularities in the circulating and intestinal metabolome which likely contributes to TCDD toxicity and can be used as biomarkers for the early detection of individual exposure.

Collection:

Collection ID:CO001942
Collection Summary:Six-week-old female wildtype (WT) C57BL/6 mice acquired from Jackson Laboratories (Bar Harbor, ME) were housed in an AAALAC-accredited specific-pathogen-free animal facility located at the grounds of the University of South Carolina School of Medicine for the entirety of all experiments. Mice within the facility were housed within polycarbonate cages containing cellulose fiber chips as bedding in a temperature and humidity-controlled environment. After a 2-week acclimatization period, the mice were divided randomly into two groups that would be administered a single 100µl intraperitoneal injection containing sterile corn oil (VEH group) or an intraperitoneal injection of 10µg/kg TCDD suspended within sterile corn oil (TCDD group). At the 72h time point following TCDD or VEH exposure, the mice were humanely euthanized by an overdose of inhaled isoflurane. Cecal content and blood sera were collected at the time of necropsy.
Sample Type:Blood (serum)

Sample Preparation:

Sampleprep ID:SP001955
Sampleprep Summary:Cecal content and serum samples were processed according to previously described methods for the metabolomic profiling using liquid chromatography-mass spectrometry (LC-MS) with slight modifications. For cecal content, ~25 mg was aliquoted into 1.5-mL Eppendorf tubes (Hamburg, Germany) containing ~20 mg acid washed glass beads (Sigma-Aldrich, St. Louis, MO), extracted into ice-cold MeOH:water (1:1, v/v) on a Qiagen TissueLyzer at 50 Hz for 10 min (Hilden, Germany), and centrifuged at 12,000 rpm for 10 min. For blood sera, 20 µL aliquots were extracted by adding 180 µL cold MeOH, briefly vortexed, and incubated at -20 ºC for 30 min for protein precipitation. The supernatants of both matrices were dried in a CentriVap vacuum concentrator (Labconco, MO) and resuspended in ACN:water (2:98, v/v) upon analysis.
