#STUDY
ST:STUDY_TITLE                   	Urea cycle and 1C/serine metabolism in the prevention of oxygen induced
ST:STUDY_TITLE                   	retinopathy
ST:STUDY_SUMMARY                 	Untargeted metabolite profiling links the urea cycle and 1C/serine metabolism in
ST:STUDY_SUMMARY                 	the prevention of oxygen induced retinopathy by hepatic HIF stabilization.
ST:STUDY_SUMMARY                 	Premature infants require oxygen supplementation to survive that is
ST:STUDY_SUMMARY                 	simultaneously toxic to developing tissues. We have demonstrated that hypoxia
ST:STUDY_SUMMARY                 	inducible factor (HIF) stabilization during hyperoxia prevents oxygen induced
ST:STUDY_SUMMARY                 	retinopathy (OIR) and lung disease. Here, untargeted metabolite profiling
ST:STUDY_SUMMARY                 	coupled to XCMS systems biology analysis finds that serine/1C and urea cycles
ST:STUDY_SUMMARY                 	dominate pathway enrichment graphs. MS1 peak areas and MS2 library matches
ST:STUDY_SUMMARY                 	reveal 50% or more increased levels of plasma and retina serine, glycine,
ST:STUDY_SUMMARY                 	hypotaurine, methionine, and taurine. In addition, N-acetylglutamate increased
ST:STUDY_SUMMARY                 	4-fold in serum, while orotate, citrulline, arginine, aspartate, glutamine were
ST:STUDY_SUMMARY                 	at least 50% increased after HIF stabilization. Targeted data analysis in vivo
ST:STUDY_SUMMARY                 	finds that retinal serine and glycine were derived from liver. HIF-1α2lox/2lox;
ST:STUDY_SUMMARY                 	albumin-cre KO had reduced levels of serine and retinal glycine. Inhibition of
ST:STUDY_SUMMARY                 	1C metabolism blocked rescue by HIF stabilization. The metabolic phenotype of
ST:STUDY_SUMMARY                 	mice protected from OIR by HIF stabilization is dependent on hepatic serine/1C
ST:STUDY_SUMMARY                 	metabolism and urea cycle.

#SAMPLEPREP
SP:SAMPLEPREP_SUMMARY            	Metabolites from plasma were extracted by adding 20 µl of plasma to 500 µl of
SP:SAMPLEPREP_SUMMARY            	50% cold acetonitrile. Samples were centrifuged at 15,000 x g for 10 min and 400
SP:SAMPLEPREP_SUMMARY            	µl supernatant was carefully removed into fresh tubes without disturbing the
SP:SAMPLEPREP_SUMMARY            	cell pellet. Supernatants were injected directly into the LC-MS
#CHROMATOGRAPHY
CH:CHROMATOGRAPHY_SUMMARY        	Chromatographic separation was performed on SeQuant ZIC-HILIC column with

CH:CHROMATOGRAPHY_SUMMARY        	(Merck, Darmstadt, Germany). The LC method used for separation of metabolites
CH:CHROMATOGRAPHY_SUMMARY        	using the ZIC-HILIC column was adapted from Singh et al. al.(Singh et al, 2017).
CH:CHROMATOGRAPHY_SUMMARY        	Briefly, gradient of solvent A (0.1% formic acid in water) and solvent B (0.08%

CH:CHROMATOGRAPHY_SUMMARY        	step with 5% B from 25-30 min and then re-equilibration with 80% B from 25-30
CH:CHROMATOGRAPHY_SUMMARY        	min. Column oven was set to 20⁰C and a constant flow of solvents was set to
CH:CHROMATOGRAPHY_SUMMARY        	150 µl min-1. Samples were kept on 4⁰C auto-sampler throughout the
