Study Title | Impact of anesthesia and euthanasia on metabolomics of mammalian tissues: studies in a C57BL/6J mouse model |
Study Type | Anesthesia effect study |
Study Summary | We 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. |

Treatment:
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. |
