Project description:A custom resequencing array for analysis of field isolates of plasmdium falciparum was created. Test of DNA with genotypes known at all loci genotyped by the microarray as well as test of accuracy correlation with amounts of DNA added to each array Comparison of test DNA from lab and clinical isolates between genotyped generated by next-generation sequencing and this new custom DNA microarray.

Project description:Investigation of whole genome gene expression level changes in Plasmodium falciparum 3D7 delta-PfPuf2 mutant, compared to the wild-type strain 3D7. The mutation engineered into this strain render tanslational control. The mutants analyzed in this study are further described in Miao J, Li J, Fan Q, Li X, Li X, Cui L.2010. The Puf-family RNA-binding protein PfPuf2 regulates sexual development and sex differentiation in the malaria parasite Plasmodium falciparum. J Cell Sci. 123(7):1039-49 (PMID 20197405). A 12 chip study using total RNA recovered from six separate wild-type cultures of Plasmodium falciparum 3D7 at gametocyte stage III (three cultures) and stage V (three cultures) and six separate cultures of dalta PfPuf2 mutant at gametocyte stage III (three cultures) and stage V (three cultures). Each chip measures the expression level of 5,367 genes from Plasmodium falciparum 3D7 with 45-60 mer probes with two replicates on final array of 71618 probes.
Project description:Transcriptomic Analysis of Cultured Sporozoites of P. falciparum RNA-seq reads from each of three developmental stages (2 replicates per sample) were mapped to the reference Plasmodium falciparum genome, and gene expression levels were calculated for each sample.
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
