PR:PROJECT_TITLE                 	Systemic host inflammation induces stage-specific transcriptomic modification
PR:PROJECT_TITLE                 	and slower maturation in malaria parasites
PR:PROJECT_TYPE                  	MS untargeted metabolomics analysis
PR:PROJECT_SUMMARY               	Previous reports suggest that the maturation rate of malaria parasites within
PR:PROJECT_SUMMARY               	red blood cells (RBC) is not constant for a given species in vivo. For instance,
PR:PROJECT_SUMMARY               	maturation can be influenced by host nutrient status or circadian rhythm. Here
PR:PROJECT_SUMMARY               	we observed in mice that systemic host inflammation, induced by
PR:PROJECT_SUMMARY               	lipopolysaccharide (LPS) conditioning or ongoing acute malaria infection, slowed
PR:PROJECT_SUMMARY               	the progression of a single cohort of parasites from one generation of RBC to
PR:PROJECT_SUMMARY               	the next. LPS-conditioning and acute infection both triggered substantial
PR:PROJECT_SUMMARY               	changes to the metabolomic composition of plasma in which parasites circulated.
PR:PROJECT_SUMMARY               	This altered plasma directly slowed parasite maturation in a manner that could
PR:PROJECT_SUMMARY               	not be rescued by supplementation, consistent with the presence of inhibitory
PR:PROJECT_SUMMARY               	factors. Single-cell transcriptomic assessment of mixed parasite populations,
PR:PROJECT_SUMMARY               	exposed to a short period of systemic host inflammation in vivo, revealed
PR:PROJECT_SUMMARY               	specific impairment in the transcriptional activity and translational capacity
PR:PROJECT_SUMMARY               	of trophozoites compared to rings or schizonts. Thus, we provide in vivo
PR:PROJECT_SUMMARY               	evidence of transcriptomic and phenotypic plasticity of asexual blood-stage

#COLLECTION
CO:COLLECTION_SUMMARY            	Two independent experiments were conducted, each with 6 mice per treatment group
CO:COLLECTION_SUMMARY            	(30 individuals in total). Mice were euthanized by CO2 asphyxiation and their
CO:COLLECTION_SUMMARY            	blood was taken by cardiac puncture into lithium-heparin coated tubes. Samples
CO:COLLECTION_SUMMARY            	were spun for 5 min at 5000 rpm (approx. 7,043 × g) and plasma was immediately
CO:COLLECTION_SUMMARY            	aliquoted into 1.5 mL tubes. In addition, a global sample pool containing equal
CO:COLLECTION_SUMMARY            	volumes of each sample was prepared as quality control (QC) and four aliquots
CO:COLLECTION_SUMMARY            	were transferred into 1.5 mL tubes. Finally, collection tube blank extractions
CO:COLLECTION_SUMMARY            	were performed in triplicate by adding 1x PBS (same volume as blood collection)
CO:COLLECTION_SUMMARY            	to lithium-heparin tubes and then transferring an aliquot into a 1.5 mL tube

#SAMPLEPREP
SP:SAMPLEPREP_SUMMARY            	Ten-times the sample volume of ice-cold butanol/methanol (1:1) containing 50
SP:SAMPLEPREP_SUMMARY            	µg/mL antioxidant 2,6-di-tert-butyl-4-methylphenol (BHT) was added to each
SP:SAMPLEPREP_SUMMARY            	sample and vortexed for 10 s. Samples were snap frozen and transported on dry
SP:SAMPLEPREP_SUMMARY            	ice. Subsequently, samples were thawed on ice and labelled in a randomized

SP:SAMPLEPREP_SUMMARY            	stored for 2 hrs at -30oC and then centrifuged for 15 min at 16,000 × g (4oC).
SP:SAMPLEPREP_SUMMARY            	Lastly, samples were aliquoted, dried down using a vacuum concentrator and
SP:SAMPLEPREP_SUMMARY            	stored at -80oC until LC/MS analysis

MS:MS_COMMENTS                   	performed as described previously. Full scan MS data (m/z 50-1700) was acquired
MS:MS_COMMENTS                   	at a scan rate of 2.5 spectra/sec (equals 3224 transients/spectrum) with the

MS:MS_COMMENTS                   	Data files (30 sample files, 6 QC files and 3 tube blank extraction files) were
MS:MS_COMMENTS                   	loaded into MassHunter Profinder (v 10 SP1, Agilent) and assigned to sample
MS:MS_COMMENTS                   	groups. Spectral feature extraction was performed using the recursive feature
MS:MS_COMMENTS                   	extraction method employing default settings with minor adjustments: Peak
