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:ChIP-seq experiments were performed to profile PfH3.3 (PF3D7_0617900) in the malaria parasite Plasmodium falciparum. Sequencing of ChIP samples showed enrichment of PfH3.3 at GC-rich coding sequences and subtelomeric repetitive regions throughout the intraerythrocytic life cycle and additionally in intergenic regions during trophozoite stages. Also the promoter and the coding sequence of the active and poised var2CSA gene were marked (reference genome Plasmodium falciparum 3D7 from PlasmoDB version 6.1)
