Study ID	ST002444
Study Title	Zebrafish Optic Nerve Regeneration Metabolomics - 3 Days Post Crush
Study Summary	Zebrafish (Danio Rerio) have the capacity for successful adult optic nerve regeneration. In contrast, mammals lack this intrinsic ability and undergo irreversible neurodegeneration seen in glaucoma and other optic neuropathies. Optic nerve regeneration is often studied using optic nerve crush, a mechanical neurodegenerative model. Untargeted metabolomic studies within successful regenerative models are deficient. Evaluation of tissue metabolomic changes in active zebrafish optic nerve regeneration can elucidate prioritized metabolite pathways that can be targeted in mammalian systems for therapeutic development. Female and male (6 month to 1 year old) right Zebrafish (Tg(gap43:GFP)) optic nerves were crushed and collected three days after. Contralateral, uninjured optic nerves were collected as controls. The tissue was dissected from euthanized fish and frozen on dry ice. Samples were pooled for each category (female crush, female control, male crush, male control) and pooled at n = 31 to obtain sufficient metabolite concentrations for analysis. Optic nerve regeneration was verified by microscope visualization of GFP fluorescence. Metabolites were extracted using a Precellys Homogenizer and a serial extraction method: (1) 1:1 Methanol/Water and (2) 8:1:1 Acetonitrile/Methanol/Acetone. Metabolites were analyzed by untargeted liquid chromatography-mass spectrometry (LC MS-MS) profiling using a Q-Exactive Orbitrap instrument coupled with Vanquish Horizon Binary UHPLC LC-MS system. Metabolites were identified and quantified using Compound Discoverer 3.3 and isotopic internal metabolites standards.

Project Title:	Regenerative Metabolomic Profiles of the Zebrafish Visual System
Project Summary:	Zebrafish (Danio Rerio) have the capacity for successful adult optic nerve regeneration. In contrast, mammals lack this intrinsic ability and undergo irreversible neurodegeneration seen in glaucoma and other optic neuropathies. Optic nerve regeneration is often studied using optic nerve crush, a mechanical neurodegenerative model. Currently, untargeted metabolomic studies within successful regenerative models are deficient. Evaluation of tissue metabolomic changes in active zebrafish optic nerve regeneration can elucidate prioritized metabolite pathways to be targeted in mammalian systems for therapeutic development. Female and male (6 month to 1 year old) right Zebrafish (Tg(gap43:GFP)) optic nerves were crushed and collected three days after. The associated retinas and tecta were also collected under the same conditions for metabolic analysis. Contralateral, uninjured optic nerves, retinas and tecta were collected as controls. The three tissue types (optic nerve, retina, and tectum) were dissected from euthanized fish and frozen on dry ice. Optic nerve samples were pooled for each category (female crush, female control, male crush, male control) and pooled at n = 31 to obtain sufficient metabolite concentrations for analysis. Retina and tectum samples were pooled using the same categories (female crush, female control, male crush, male control) at n = 10-12. Regeneration was verified by microscope visualization of GFP fluorescence. Metabolites were extracted using a Precellys Homogenizer and a serial extraction method: (1) 1:1 Methanol/Water and (2) 8:1:1 Acetonitrile/Methanol/Acetone. Metabolites were analyzed by untargeted liquid chromatography-mass spectrometry (LC MS-MS) profiling using a Q-Exactive Orbitrap instrument coupled with Vanquish Horizon Binary UHPLC LC-MS system.

Collection:

Collection ID:	CO002526
Collection Summary:	For tissue collection, animals were euthanized by overdose of MS-222 and optic nerve removed by dissection from the optic nerve head to the optic chiasm. Female and male Zebrafish optic nerves were collected separated and are separate biological samples. Due to the small tissue and metabolomics resolution constraints, optic nerves were pooled to generate higher signal intensities. 31 and 36 crushed optic nerves were pooled for female and male zebrafish samples, respectively. The contralateral uncrushed optic nerves were pooled in the same way.
Sample Type:	Eye tissue

Treatment:

Treatment ID:	TR002545
Treatment Summary:	For optic nerve crush, animals were deeply anesthetized in 0.033% tricaine methane-sulfonate (MS-222). The right optic nerve was exposed by gently removing the connective tissue on the dorsal half of the eye and rotating the eye ventrally out of the orbit with a number 5 forceps. A nerve crush was then performed using number 5 forceps to crush the nerve ~0.5–1 mm from the optic nerve head for 5 s. Success was observed by the generation of a translucent stripe in the nerve that completely separated two areas of white myelination with no bleeding. Fish were then revived in fresh aquatic system water in individual tanks. After 1 h the tanks were returned to the fish system and animals were maintained normally with daily feeding until 3 days post injury.

Sample Preparation:

Sampleprep ID:	SP002539
Sampleprep Summary:	Metabolite extraction from samples was carried out quickly while keeping optic nerve tissues on dry ice to prevent metabolite degradation. Tissues were transferred to 0.5mL Soft Tissue Lysing Kit Precellys tubes containing beads. Add 84 µL of chilled 1:1 MeOH/H2O to Precellys tube. Pre-extraction internal standards were added to the tubes. Add pre-extraction internal standards: 5µl of 1mg/ml Caffeine 13C6, 5µl of 1mg/ml D-Glucose 13C6, 5µl of 1mg/ml Oleic Acid 13C5, and 1µl of 5mg/mL Isoleucine 13C6 to each sample. Tissues were homogenized using Precellys 24 Touch. Cycle parameters: 2 cycles: 30 seconds homogenization at 4500 rpm, 10 seconds rest. Transfer homogenate to microcentrifuge tube and centrifuge at 18000xrcf for 20 min at 4°C. Collect supernatant and transfer pellet to Precellys Lysing Kit tube. Add 84uL of 8:1:1 Acetonitrile/Methanol/Acetone to pellet and add the rest of the pre-extraction internal standards: 5µl of 1mg/ml Caffeine 13C6, 5µl of 1mg/ml D-Glucose 13C6, 5µl of 1mg/ml Oleic Acid 13C5, 1µl of 5mg/mL Isoleucine 13C6. Final pre-extraction internal standards concentrations are 50μg/mL. Homogenization cycles were repeating using Precellys 24 Touch. Centrifuge as before and add second supernatant to first round of collected supernatant. Centrifuge at 1800xrcf for 20 min once more to remove any remaining tissue debris. Collect supernatant and dry supernatant in Speedvac. Two extraction blanks were prepared in the same manner as the biological samples. Dried samples were reconstituted immediately in 0.1% formic acid in 44.75µL of HPLC-MS grade water. Post-extraction internal standards were added: 25 µl of 5mg/ml Phenylalanine 13C6, 2.5 µl of .5mg/ml Uracil 13C 15N2, 1.25 µl of 1mg/ml Arginine 13C6, 1.25 µl of 1mg/ml Serine 13C3 to each sample.
