摘要: Background The emergence of artemisinin resistance in the malaria parasite Plasmodium falciparum poses a major threat to control and elimination malaria. Certain point mutations propeller domain PfKelch13 are associated with resistance, but do not always result clinical resistance. underlying mechanisms poorly understood, impact on cellular biochemistry is defined. Methods This study aimed identify global biochemical differences between PfKelch13-mutant artemisinin-resistant -sensitive strains P. by combining liquid chromatography-mass spectrometry (LC-MS)-based proteomics, peptidomics, metabolomics. Results Proteomics analysis found both examined be specifically decreased abundance protein. Metabolomics demonstrated accumulation glutathione its precursor, gamma-glutamylcysteine, significant depletion 1 other putative metabolite resistant strains. Peptidomics revealed lower several endogenous peptides derived from hemoglobin (HBα HBβ) Conclusion lead protein, digestion, enhanced production.
