Study TitleImpact of anesthesia and euthanasia on metabolomics of mammalian tissues: studies in a C57BL/6J mouse model
Study TypeAnesthesia effect study
Study SummaryWe examined the effect of several commonly-used methods of anesthesia and euthanasia for collection of skeletal muscle, liver, heart, adipose and serum of C57BL/6J mice. The data revealed tissue-specific impacts of different anesthesia and euthanasia strategies. Based on these findings, we present a more optimal collection strategy mammalian tissues and recommend that rodent tissues intended for metabolomics studies be collected under anesthesia rather than post-euthanasia.

Project Title:Impact of anesthesia and euthanasia on metabolomics of mammalian tissues: studies in a C57BL/6J mouse model
Project Type:Anesthesia effect study
Project Summary:We examined, for the first time using untargeted and targeted metabolomics, the effect of several commonly-used methods of anesthesia and euthanasia for collection of skeletal muscle, liver, heart, adipose and serum of C57BL/6J mice. The data revealed tissue-specific impacts of different anesthesia and euthanasia strategies. Based on these findings, we present a more optimal collection strategy mammalian tissues and recommend that rodent tissues intended for metabolomics studies be collected under anesthesia rather than post-euthanasia.

Collection ID:CO000124
Collection Summary:4 tissues plus blood serum were collected and immediately following euthanasia or anesthesia induction, frozen in liquid nitrogen and stored at -80C until analysis
Sample Type:Skeletal muscle (gastrocnemius), Liver, Heart, Epididymal white adipose (fat), blood serum
Collection Method:Surgical dissection
Collection Time:As soon as possible following anesthesia/euthanasia (all tissues collected within 3 minutes)
Storage Conditions:-80 C


Treatment ID:TR000142
Treatment Summary:Mice were prepared or tissue collection by one of 6 modes of anesthesia or euthanasia, then tissues were rapidly surgically collected and frozen
Animal Anesthesia:One of 6 methods: 1) Cervical dislocation, 2) Carbon dioxide inhalation, 3) Isoflurane overdose, 4) continuous isoflurane, 5) ketamine, 6) pentobarbital
Animal Fasting:5 hours
Animal Endp Euthanasia:All tissue collection were terminal studies; in methods 1-3, animals were euthanized prior to tissue collection; in methods 4-6, animals were under deep anesthesia while tissues were collected.

Sample Preparation:

Sampleprep ID:SP000137
Sampleprep Summary:Frozen tissue samples were pulverized in a liquid nitrogen-chilled mortar and pestle, then sonicated in cold extraction solvent (7:2:1 methanol:chloroform:water) at an approximate ratio of 30 mg tissue (wet mass) /1 mL of solvent. After allowing samples to rest on ice 5 minutes, they were centrifuged to pellet precipitated protein and cell debris; the supernatant was placed in autosampler vials for direct LC-MS analysis. For serum, extraction solvent (1:1:1 methanol:acetonitrile:acetone) was added to serum at a 4:1 solvent:serum ratio, vortexed to mix, then centrifuged and supernatant recovered for LC-MS analysis.
