Study TitleZebrafish Retina Regeneration Metabolomics - 3 Days Post Crush
Study SummaryRetinal regeneration has been at the forefront of optic research. Regenerative model organisms provide key information regarding treatment for optic nerve and retinal degeneration in mammalian species; specifically, Zebrafish (Danio Rerio) have the capacity for successful adult retinal regeneration. Mammals, however, lack this intrinsic ability and undergo irreversible neurodegeneration seen in glaucoma, diabetes and other optic neuropathies. Optic nerve and retinal regeneration are often studied using the retina obtained via optic nerve crush, a mechanical neurodegenerative model. Untargeted metabolomic studies within successful regenerative models are deficient. Evaluation of tissue metabolomic changes in active zebrafish retinal 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 the retinas were collected three days after. Contralateral, uninjured optic nerve retinas 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 = 10-12 to obtain sufficient metabolite concentrations for analysis. Retinal 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. Metabolites were identified and quantified using Compound Discoverer 3.3 and isotopic internal metabolite standards.

Collection:

Collection ID:CO002875
Collection Summary:In the tissue collection process, mice were euthanized using an overdose of MS-222. The optic nerve was removed via dissection from the optic nerve head to the optic chiasm. The retinas of both female and male Zebrafish were collected and separated into biological samples. Due to the small tissue and metabolomics resolution constraints, optic nerves were pooled to generate higher signal intensities. A total of 10-11 and 12 retinas were pooled from female and male zebrafish samples, respectively. The untreated retinas were pooled using the same protocol.
Sample Type:Eye tissue

Treatment:

Treatment ID:TR002891
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:SP002888
Sampleprep Summary:Retinas remained on dry ice to prevent metabolite degradation while the metabolite extraction was conducted. Tissues were transferred to 0.5mL Soft Tissue Lysing Kit Precellys tubes containing beads. Then, 84 µL of chilled 1:1 MeOH/H2O were added to Precellys tube. Pre-extraction internal standards were added to the tubes: 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. Homogenate was transferred to a microcentrifuge tube and centrifuged at 18000xrcf for 20 min at 4°C. Then, 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.
