#PROJECT
PR:PROJECT_TITLE                 	Mayo Pilot and Feasiblity: Targeting Myelin Metabolism of Kallikrein 6 Signals
PR:PROJECT_TITLE                 	through PAR1 and PAR2 to Enchance Recovery of Function after SCI
PR:PROJECT_SUMMARY               	CNS trauma generates a proteolytic imbalance contributing to secondary injury,
PR:PROJECT_SUMMARY               	including axonopathy and neuron degeneration. Kallikrein 6 (Klk6) is a serine
PR:PROJECT_SUMMARY               	protease implicated in neurodegeneration and here we investigate the role of
PR:PROJECT_SUMMARY               	protease activated receptors 1 (PAR1) and PAR2 in mediating these effects in
PR:PROJECT_SUMMARY               	mice with spinal cord injury (SCI). This project conducts untargeted Profiling
PR:PROJECT_SUMMARY               	(unbiased metabolomics assay) and targeted lipid analysis. The lipid assays are
PR:PROJECT_SUMMARY               	1) free fatty acid composition of lipids; 2) free fatty acid panel; 3)
PR:PROJECT_SUMMARY               	cholesterol concentration (free and bound); 4) Ceramides, including galactosyl
PR:PROJECT_SUMMARY               	and glucosyl; 5) sphingomyelin.

#COLLECTION
CO:COLLECTION_SUMMARY            	Tissue is from adult mouse spinal cord (SC). We are submitting these samples for
CO:COLLECTION_SUMMARY            	Untargeted Profiling (unbiased metabolomics assay) and for lipid analysis. The
CO:COLLECTION_SUMMARY            	lipid assays we request are 1) free fatty acid composition of lipids; 2) free
CO:COLLECTION_SUMMARY            	fatty acid panel; 3) cholesterol concentration (free and bound); 4) Ceramides,
CO:COLLECTION_SUMMARY            	including galactosyl and glucosyl; 5) sphingomyelin. The Untargeted profiling is
CO:COLLECTION_SUMMARY            	our top priority, followed by the lipid assays as listed. All samples were snap
CO:COLLECTION_SUMMARY            	frozen at the point of harvest and approximate weights are provided. The samples
CO:COLLECTION_SUMMARY            	are submitted as intact pieces of tissue. There are two different genotypes
CO:COLLECTION_SUMMARY            	(K6+/+ and K6-/-) and 20 samples total, n=5 for each group that includes
CO:COLLECTION_SUMMARY            	P21(K6+/+); P90 (K6+/+); P21 (K6-/-); and P90 (K6-/-). We would like to make
CO:COLLECTION_SUMMARY            	comparisons across the 4 groups.
#TREATMENT
TR:TREATMENT_SUMMARY             	A 3g Clip produces moderate SCI including demyelination and clinical impairment
TR:TREATMENT_SUMMARY             	and we recently published a detailed methodology. At 1 week after injury, the 3g
TR:TREATMENT_SUMMARY             	injured mice are expected to have an average Basso Mouse Scale score (BMS)=5 on
TR:TREATMENT_SUMMARY             	a 9 point scale such that they have frequent plantar stepping with no or some
TR:TREATMENT_SUMMARY             	coordination. This level of impairment was chosen to provide a sufficient window
TR:TREATMENT_SUMMARY             	to observe recovery.
#SAMPLEPREP
SP:SAMPLEPREP_SUMMARY            	"Sphingolipids of mouse spinal cord Lipids will be quantified in myelin isolated
SP:SAMPLEPREP_SUMMARY            	in high yield and purity by subcellular fractionation from the lumbosacral
SP:SAMPLEPREP_SUMMARY            	spinal cord. While there are no absolutely ‘myelin-specific’ lipids,
SP:SAMPLEPREP_SUMMARY            	galactocerebroside is the most typical of myelin in the adult nervous system
SP:SAMPLEPREP_SUMMARY            	being directly proportional to the amount of myelin. Sulfatide is another
SP:SAMPLEPREP_SUMMARY            	galactolipid enriched in myelin. Together with cholesterol, these form 78% of
SP:SAMPLEPREP_SUMMARY            	the total amount of lipid in the myelin membrane and each will be quantified
SP:SAMPLEPREP_SUMMARY            	using LC/MS/MS. A highly sensitive assay for galactocerebroside was recently
SP:SAMPLEPREP_SUMMARY            	established by the Mayo Metabolomics Core and can be implemented immediately.
SP:SAMPLEPREP_SUMMARY            	The LC/MS/MS panel for free fatty acids, including the very long chain fatty
SP:SAMPLEPREP_SUMMARY            	acids found in myelin is also routinely performed by the Core. Cholesterol will
SP:SAMPLEPREP_SUMMARY            	be quantified using an NMR-based approach by the Mayo Dept. of Laboratory
SP:SAMPLEPREP_SUMMARY            	Medicine Clinical Core. Additionally, we have a plan in place with the
SP:SAMPLEPREP_SUMMARY            	Metabolomics Core to develop LC/MS/MS assays for sulfatide and sphingomyelin
SP:SAMPLEPREP_SUMMARY            	during the Pilot proposal. Having quantitative assays for each of these key
SP:SAMPLEPREP_SUMMARY            	myelin lipids will facilitate our goal to comprehensively profile myelin lipid
SP:SAMPLEPREP_SUMMARY            	metabolism and will form foundational assays for a future NIH grant focused on
SP:SAMPLEPREP_SUMMARY            	myelin metabolism."
