Project description:In this project we use MS2-based 6-plex TMT quantitation to compare phosphorylation site abundances across several stages of the Plasmodium falciparum life cycle in wild-type Plasmodium and in a strain whose PK7 has been knocked out. See Pease et al. (2018) J. Proteome Res. for details.

Project description:Epigenetic mechanisms have been poorly understood in Plasmodium falciparum, the causative agent of malaria. To elucidate stage specific epigenetic regulations in P. falciparum, we performed genome-wide mapping of various histone modifications, nucleosomes and RNA Polymerase II. Our comprehensive analysis suggest that transcription initiation and elongation are distinct in Plasmodium. In this study, by analyzing histone modifications, nucleosome occupancy and RNA Polymerase II (Pol II) at three different IEC developmental stages of Plasmodium; ring, trophozoite and schizont, we tried to unravel the epigenetic mechanism associated with gene regulation. Examination of H3K27me3, H3K4me3, H3K9me3, H3K14ac, H3K4me1, H3K79me3, H3K27ac, H3K4me2, H3K9ac, H4ac, RNA Pol II and Histone H3 at three different stages of Plasmodium falciparum
Project description:The aim of this study was to describe gene copy number variation in Plasmodium falciparum parasites sourced from high vs. low malaria transmission settings in east Africa in order to test the hypothesis that malaria parasites are locally adapted to their environment. In three separate experiments, parasites from ‘High’ vs. ‘Low’ transmission populations were taken from non-immune children and evaluated for copy number variants by microarray against a reference genome. Two of these population comparisons were geographic in nature while the third was temporal, i.e., before and after a marked decline in malaria. This study is described in Simam et al. 2018 BMC Genomics.
