Quantitative proteome profiling of Leishmania donovani after hypericin treatment


ABSTRACT: Hypericin, a novel inhibitor of spermidine synthase of Leishmania donovani, has been found to cause necrotic like death of the parasite. Hypericin treatment has indicated the importance of spermidine in pathways other than redox metabolism of Leishmania parasite. We have used label free quantitative proteomics approach to compare the alteration in expression of proteins in untreated and hypericin treated Leishmania promastigotes.

We have earlier reported antileishmanial activity of hypericin by spermidine starvation. In the current report, we have used label free proteome quantitation approach to identify differentially modulated proteins after hypericin treatment. A total of 141 proteins were found to be differentially regulated with ANOVA P value less than 0.05 in hypericin treated Leishmania promastigotes. Differentially modulated proteins have been broadly classified under nine major categories. Increase in ribosomal  ...[more]
