Study TitleMetabolomic profiling of the rat hippocampus across developmental ages and after learning
Study TypeDevelopmental study
Study SummaryLittle is known about how the hippocampal metabolomic profile changes across development and in response to learning at different ages. To fill this knowledge gap, we employed an untargeted metabolomic analyses in rats to determine how the hippocampal metabolome changes over the course of post-natal development under basal conditions and following inhibitory avoidance (IA) training, an aversive episodic event. We found that unique metabolomic profiles accompany learning at different ages. Subsequent biochemical and behavioral studies based on unique metabolomic regulations in the infant hippocampus established that infantile learning selectively recruits the glutathione-mediated antioxidant defenses for the formation of infantile memory.

Collection ID:CO001815
Collection Summary:Rats trained in inhibitory avoidance at PN17, PN24, and PN80, and the untrained (naive) control rats were euthanized by decapitation (1 hour after IA training). Their brains were quickly removed and placed in ice-cold phosphate-buffered saline (1X). Whole hippocampal samples were dissected and immediately snap-frozen in isopentane on dry ice. All samples were stored at -80°C until processing. Frozen samples were shipped in dry ice to Metabolon Inc. (Morrisville, NC, USA) for metabolomic analysis using a proprietary methodology. Extraction of samples was performed using a MicroLab STAR automated liquid handling robot (Hamilton Robotics, Inc., Reno, NV, USA); 450 μL of methanol was added to 100 μo of sample to precipitate proteins. Four recovery standards (DL-2-fluorophenylglycine, tridecanoic acid, cholesterol-d6 and 4-chlorophenylalanine) were added to each sample to determine extraction efficiency. To remove proteins, dissociate small molecules bound to protein, and recover metabolites, proteins were precipitated with methanol under vigorous shaking for 2 min (Glen Mills GenoGrinder 2000) followed by centrifugation (1300 g for 10 min at room temperature). The resultant supernatants were placed in a TurboVap (Zymark) to remove the organic solvent. Each sample extract was then divided into five equal aliquots, dried under nitrogen, and stored in vacuo prior to metabolomic profiling.
