Study ID	ST003460
Study Title	Metabolomics of mice serum to support understanding of early metabolic shift in presymptomatic sepsis patients. (Part6 mice serum metabolite)
Study Summary	Sepsis, a life-threatening organ dysfunction caused by a dysregulated response to infection, is a critical medical condition with significant global impact, responsible for 48.9 million cases and 11 million deaths annually. Metabolic dysregulation in sepsis is a critical determinant of disease outcome, yet most studies focus on patients after severe illness onset, comparing septic versus non-septic groups or survivors versus non-survivors. To truly understand this complex disease, it is essential to investigate early metabolic shifts, capturing the transition from simple infection to sepsis. Our untargeted metabolome analysis of serum tissues from mice model revealed early septic biomarkers in serum.

Collection:

Collection ID:	CO003581
Collection Summary:	Mice tissue samples were collected from our in vivo mice model and frozen at -80 °C. Samples were shipped to MS-OMICS for metabolomic analysis.
Sample Type:	Blood (serum)

Treatment:

Treatment ID:	TR003597
Treatment Summary:	Approximately 30% of the cecum was ligated and punctured twice with a 23 Gauge (G) needle. A small amount of faeces was extruded and the cecum was placed back into the abdominal cavity. All animals received 40 mL/kg saline s.c. directly after the procedure and once 25mg/kg s.c. Imipenem/Cilastatin after 6 hours. This model is associated with a 14-day mortality of 30%, closely mimicking the clinical situation. Animals were orally gavaged with 500mg/kg 12C-Serin (Sigma) or 13C-Serin (CLM-1574-H-0.25 Serine-L (13C3 99%13C), Euroisotope, Germany) in 10mL/kg drinking water or drinking water only (vehicle) 6 and 18 hours after CLP98,99. After 24 hours, the animals are then perfused with ice cold PBS and organs were harvested, snap frozen and stored at -80° until further analysis. Sham animals underwent exactly to the same procedures except for the CLP.

Sample Preparation:

Sampleprep ID:	SP003595
Sampleprep Summary:	To prepare samples for semi-polar metabolites extraction, the different tissue samples were weighted and transferred to Eppendorf tubes. Ceramic beads and precooled methanol/water (1:2) were added. All tubes were placed in a pre-cooled (-20°C) bead beater and homogenized (4 x 30 sec., 30 Hz) followed by ultrasonication (5 min). After centrifugation (18000 RCF, 5 min, 4°C), the supernatant was collected. The sample pellet was reextracted as described above. The two extract supernatants were pooled and passed through a phosphor removal cartridge (Phree filter plates). A precise aliquot of the extract was evaporated to dryness under a gentle stream of nitrogen, before reconstitution with 10% Eluent B in Eluent A. All Samples were diluted 5 times in mobile phase eluent A and stable isotope labelled standards were added before analysis. Mouse serum (50 μl) was diluted with a mixture of acetonitrile and methanol (200 μl 1:1 v/v). The extract was then passed through a phosphor removal cartridge (Phree, Phenomenex). An aliquot (100 μl) was transferred into a high recovery HPLC vial and the solvent was removed under a gentle flow of nitrogen. Extracts were reconstituted in a mobile phase mixture (100 μl, 10%B in 90%A). To ensure high-quality sample preparation, a quality control sample (QC sample) was prepared by pooling small equal aliquots from each sample, to create a representative average of the entire set.
