| Project Title: | Lipidomics of deep-diving pinniped brains |
| Project Summary: | The brain of diving mammals such as the hooded seal (Cystophora cristata) exhibits a remarkable tolerance to low tissue oxygen levels (hypoxia). While neurons of most terrestrial mammals suffer irreversible damage after only short periods of hypoxia, in vitro experiments revealed that neurons of the hooded seal show prolonged functional integrity even in severe hypoxia. As major components of membranes, specific neuronal lipids of diving mammals could contribute to the observed high hypoxia tolerance. Therefore, we analyzed the brain lipidome of deep-diving pinnipeds (Cystophora cristata, Pagophilus groenlandicus) in comparison to terrestrial (non-diving) relatives (Mustela putorius furo, Mus musculus). Furthermore, lipid composition of C. cristata brain tissue was analyzed that was exposed to hypoxia and reoxygenation in vitro. |
