PR:PROJECT_SUMMARY The emergence of multidrug resistance in Plasmodium falciparum parasites PR:PROJECT_SUMMARY presents a significant obstacle to the malaria elimination agenda. Resistance to PR:PROJECT_SUMMARY piperaquine (PPQ), an important first-line partner drug, has spread across PR:PROJECT_SUMMARY Southeast Asia where it has contributed to widespread treatment failures. The PR:PROJECT_SUMMARY genetic cause of resistance to PPQ is attributable to a novel set of amino acid PR:PROJECT_SUMMARY substitutions in the P. falciparum chloroquine resistance transporter (PfCRT). PR:PROJECT_SUMMARY In this study, we used magnetically-purified trophozoite extracts from seven PR:PROJECT_SUMMARY different lines comprising five genetically-modified and two field isolates. PR:PROJECT_SUMMARY Three independent extractions with triplicate technical repeats were run by mass PR:PROJECT_SUMMARY spectrometry on positive and negative modes and spectral peak raw data analyzed PR:PROJECT_SUMMARY to obtain the fold change difference between the samples and parental control, PR:PROJECT_SUMMARY Dd2Dd2crt. We show that PPQ-resistant, PfCRT mutant asexual blood stage PR:PROJECT_SUMMARY parasites accumulate higher levels of hemoglobin-derived peptides than do their PR:PROJECT_SUMMARY PPQ-sensitive counterparts.

Trophozoite counts were determined on a CO:COLLECTION_SUMMARY hemocytometer. Parasites were lysed in 1 mL of 90% cold methanol, containing 0.5 CO:COLLECTION_SUMMARY μM of the internal standard [13C4, 15N1]-Aspartate (Cambridge Isotope) to CO:COLLECTION_SUMMARY correct for technical variations arising from sample processing. Samples were CO:COLLECTION_SUMMARY vortexed to disrupt cell pellets and to generate uniform homogenates, which were CO:COLLECTION_SUMMARY centrifuged (13,000´ g for 10 min) and the supernatants then harvested. CO:COLLECTION_SUMMARY Supernatants were dried under nitrogen prior to resuspension in HPLC-grade water CO:COLLECTION_SUMMARY for LC-MS analysis. CO:SAMPLE_TYPE Plasmodium cells #TREATMENT TR:TREATMENT_SUMMARY Cells were all untreated, but had different genetic backgrounds. #SAMPLEPREP SP:SAMPLEPREP_SUMMARY Supernatants were dried under nitrogen prior to resuspension in HPLC-grade water SP:SAMPLEPREP_SUMMARY for LC-MS analysis.

Solvent A was HPLC grade CH:CHROMATOGRAPHY_SUMMARY water with 0.1% formic acid and Solvent B was HPLC grade acetonitrile with 0.1% CH:CHROMATOGRAPHY_SUMMARY formic acid. The initial condition were 97% A and 3 % B, increasing to 45% B at CH:CHROMATOGRAPHY_SUMMARY 10 min, 75% B at 12 min where it was held at 75% B until 17.5 min before CH:CHROMATOGRAPHY_SUMMARY returning to the initial conditions.
