Study ID	ST003464
Study Title	Lipidomics of mice heart to support understanding of early metabolic shift in presymptomatic sepsis patients. (Part9 mice heart lipid)
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 lipidome analysis of heart from mice model revealed early septic biomarkers in heart.

Collection:

Collection ID:	CO003585
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:	Heart

Treatment:

Treatment ID:	TR003601
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:	SP003599
Sampleprep Summary:	In the different tissue samples, the pellet from the semipolar extraction were used to extract lipids as follows. DCM:MeOH (3:1) were added to the pellets, and the samples were homogenized using a pre-cooled Bead-beater (4 x 60 sec at 30 Hz), with colling of the blocks between the beading cycles. Subsequently, the samples were ultrasonicate for 5 mins and centrifuged (5 mins, 1800 RCF, 4 °C). The supernatant were collected and dried under nitrogen gas. Samples were then reconstitute with 6x (spleen and WAT) or 3x (heart, liver and kidney) the sample weight with the reconstitution solvent eluent mix and vortex mixed for 30 sec. The reconstituted samples were filtrated using SpinX filters by centrifugation (5 mins, 1800 RCF, 4 °C). All samples were mixed 1: 50 in eluent mix. For serum samples, an alliqoute of the serum samples are mixed with extraction solvent (0.1 M BHT in isopropanol with stable isotope labelled internal standard) in a Spin-X® filter. The filters were vortex-mixed for 60 sec and left at room temperature for 10 mins before placing in -20 °C Freezer overnight. The following day samples were left at room temperature for 30 mins before centrifuging (1800g /4°C/2 min). The filtrate were mixed with eluent mix 1:3.
