Study TitleA Metabolome Atlas of the Aging Mouse Brain
Study SummaryThe mammalian brain relies on neurochemistry to fulfill its functions. Yet, the complexity of the brain metabolome and its changes during diseases or aging remains poorly understood. To start bridging this gap, we generated a metabolome atlas of the aging mouse brain from 10 anatomical regions spanning from adolescence to late adulthood. We combined data from three chromatography-based mass spectrometry assays and structurally annotated 1,709 metabolites to reveal the underlying architecture of aging-induced changes in the brain metabolome. Overall differences between sexes were minimal. We found 94% of all metabolites to significantly differ between brain sections in at least one age group. We also discovered that 90% of the metabolome showed significant changes with respect to age groups. For example, we identified a shift in sphingolipid patterns during aging that is related to myelin remodeling in the transition from adolescent to adult brains. This shift was accompanied by large changes in overall signature in a range of other metabolic pathways. We found clear metabolic similarities in brain sections that were functionally related such as brain stem, cerebrum and cerebellum. In cerebrum, metabolic correlation patterns got markedly weaker in the transition from adolescent to ear adults, whereas correlation patterns between cerebrum and brainstem regions decreased from early to late adulthood. We were also able to map metabolic changes to gene and protein brain atlases to link molecular changes to metabolic brain phenotypes. Metabolic profiles can be investigated via This new resource enables brain researchers to link new metabolomic studies to a foundation data set.

Collection ID:CO001707
Collection Summary:Brain tissue samples were collected from 3 weeks, 16 weeks and 59 weeks old male and female wild type mice on a C57BL/6NCrl background and performed under approved institutional IACUC protocols. Briefly, mice were anesthetized with 4% Isoflurane in 100% oxygen at a flow rate of 3 L/h to a surgical plane. Blood was then collected by retro-orbital bleed into an EDTA tube and centrifuged at 3000 rpm for 15 min to separate and remove plasma. While under anesthsia mice were perfused for approximately 10 minutes with phosphate buffered saline (PBS) pH 7.4 at room temperature. Following perfusion, the brain was removed and placed in a petri dish containing PBS at 4oC for dissection of individual brain regions. A dissection microscope, fine tip (#5) forceps, and razor blade was used to isolate and separate brain regions (olfactory bulb, hippocampus, hypothalamus, thalamus, midbrain, cerebellum, pons, medulla, cerebral cortex, and basal ganglia collected as caudate putamen and basal forebrain) in induvial mice while being careful to avoid contamination from neighboring regions. Briefly, after separating the olfactory bulbs, the left and right cerebral cortices were then removed while taking care not to disrupt the regions underneath. This enabled access to and removal of the left and right hippocampus. After cutting along the thalamus, the left and right caudate putamen was separated and removed from the basal forebrain. Subsequently, the cerebellum and midbrain were isolated and removed, followed by separation and removal of the thalamus and the hypothalamus from the pons and medulla. The pons was then separated from the medulla. Any spinal cord remaining on the medulla was removed. Each region was immediately placed in a cryo vial and flash frozen in liquid nitrogen for analysis.
