Comparison of gene expression between wild type and AP2-G KO parasites.

ABSTRACT: In the rodent malaria parasite Plasmodium berghei, we found that an AP2 family transcription factor designated AP2-L plays a critical role in the development of the liver stage. Using DNA microarray analysis we showed that the expression of several genes, including those of parasitophorous vacuole membrane proteins, was significantly decreased in the early liver stage of AP2-L-depleted parasites. Gene expression of P. berghei sporozoites was compared between wild type and AP2-G KO parasites. Five biologically independent experiments were performed for each genotype.

Comparison of gene expression between wild type and AP2-L KO parasites

Project description:In the rodent malaria parasite Plasmodium berghei, we found that an AP2 family transcription factor designated AP2-L plays a critical role in the development of the liver stage. Using DNA microarray analysis we showed that the expression of several genes, including those of parasitophorous vacuole membrane proteins, was significantly decreased in the early liver stage of AP2-L-depleted parasites. Gene expression of P. berghei liver stages was compared between wild type and AP2-L KO parasites. Liver stage parasites were cultured for 24h using HepG2 cells. Ten and seven biologically independent experiments were performed for wild type and AP2-L KO parasites, respectively.

RNA-seq of liver stage-derived parasites from wild-type and TCRδ-/- mice

Project description:P. berghei ANKA parasites were collected from the blood at 74h after infection of wild-type and TCRδ-/- mice with 2x10^4 sporozoites (samples were pooled from 3 mice/ group) and mRNA was sequenced by RNA-seq.

Induction of target genes of AP2-Sp in AP2-O::Sp parasites

Project description:Sporozoite-specific genes were induced in parasites that express AP2-O whose AP2 domain was swapped with that of AP2-Sp. DNA construct encoding AP2 domain of AP2-Sp was introduced into P. bergei schizonts. It was integrated into the locus of the endogenious AP2-O gene, resulting in swap of the AP2-domain (AP2-O::Sp parasites). Gene expression was analyzed in ookinetes cultured for 20h.

Transcription activated by AP2-Z in early zygote plays an essential role in Plasmodium ookinete development [ChIP-seq]

Project description:To investigate the genome-wide binding sites of early zygote AP2-family transcription factor, AP2-Z in Plasmodium berghei, the chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) analyses were performed. Parasites expressing GFP-fused AP2-Z (AP2-Z::GFP) were harvested at 6 hours post starting ookinete culture (hpoc) and subjected to ChIP-seq experiments using anti-GFP antibody. Binding sites of AP2-Z were determined from the sequence data.
