"PROJECT":{"PROJECT_TITLE":"Mayo Pilot and Feasiblity: Targeting Myelin Metabolism of Kallikrein 6 Signals through PAR1 and PAR2 to Enchance Recovery of Function after SCI","PROJECT_SUMMARY":"CNS trauma generates a proteolytic imbalance contributing to secondary injury, including axonopathy and neuron degeneration. Kallikrein 6 (Klk6) is a serine protease implicated in neurodegeneration and here we investigate the role of protease activated receptors 1 (PAR1) and PAR2 in mediating these effects in mice with spinal cord injury (SCI). This project conducts untargeted Profiling (unbiased metabolomics assay) and targeted lipid analysis. The lipid assays are 1) free fatty acid composition of lipids; 2) free fatty acid panel; 3) cholesterol concentration (free and bound); 4) Ceramides, including galactosyl and glucosyl; 5) sphingomyelin.","INSTITUTE":"Mayo Clinic","LAST_NAME":"Scarisbrick","FIRST_NAME":"Isobel","ADDRESS":"200 First Street SW, Rochester, MN 55905","EMAIL":"scarisbrick.isobel@mayo.edu","PHONE":"507-284-0124"},

"COLLECTION":{"COLLECTION_SUMMARY":"Tissue is from adult mouse spinal cord (SC). We are submitting these samples for Untargeted Profiling (unbiased metabolomics assay) and for lipid analysis. The lipid assays we request are 1) free fatty acid composition of lipids; 2) free fatty acid panel; 3) cholesterol concentration (free and bound); 4) Ceramides, including galactosyl and glucosyl; 5) sphingomyelin. The Untargeted profiling is our top priority, followed by the lipid assays as listed. All samples were snap frozen at the point of harvest and approximate weights are provided. The samples are submitted as intact pieces of tissue. There are two different genotypes (K6+/+ and K6-/-) and 20 samples total, n=5 for each group that includes P21(K6+/+); P90 (K6+/+); P21 (K6-/-); and P90 (K6-/-). We would like to make comparisons across the 4 groups."},

"TREATMENT":{"TREATMENT_SUMMARY":"A 3g Clip produces moderate SCI including demyelination and clinical impairment and we recently published a detailed methodology. At 1 week after injury, the 3g injured mice are expected to have an average Basso Mouse Scale score (BMS)=5 on a 9 point scale such that they have frequent plantar stepping with no or some coordination. This level of impairment was chosen to provide a sufficient window to observe recovery."},

"SAMPLEPREP":{"SAMPLEPREP_SUMMARY":"Sphingolipids of mouse spinal cord Lipids will be quantified in myelin isolated in high yield and purity by subcellular fractionation from the lumbosacral spinal cord. While there are no absolutely ‘myelin-specific’ lipids, galactocerebroside is the most typical of myelin in the adult nervous system being directly proportional to the amount of myelin. Sulfatide is another galactolipid enriched in myelin. Together with cholesterol, these form 78% of the total amount of lipid in the myelin membrane and each will be quantified using LC/MS/MS. A highly sensitive assay for galactocerebroside was recently established by the Mayo Metabolomics Core and can be implemented immediately. The LC/MS/MS panel for free fatty acids, including the very long chain fatty acids found in myelin is also routinely performed by the Core. Cholesterol will be quantified using an NMR-based approach by the Mayo Dept. of Laboratory Medicine Clinical Core. Additionally, we have a plan in place with the Metabolomics Core to develop LC/MS/MS assays for sulfatide and sphingomyelin during the Pilot proposal. Having quantitative assays for each of these key myelin lipids will facilitate our goal to comprehensively profile myelin lipid metabolism and will form foundational assays for a future NIH grant focused on myelin metabolism."},
