Project description:Plasmodium berghei transcriptomes of wild-type and ap2-z knockout parasites [ap2-z(-)] were analyzed at 6 hours post starting ookinete culture (hpoc).
Project description:Transcriptional profiling of gametocyte non-producer lines in Plasmodium berghei Transcriptome of gametocyte non producer lines (natural and genetic KO) and parental (820) lines. The aim of the study was to identify key genes involved in the decision to commit to gametocytogenesis in Plasmodium berghei. These microarrays compare naturally selected lines that do not produce gametocytes, and the parental line and additionally a genetic knock out of AP2-G PBANKA_143750. Data published Sinha, Hughes, et, al Nature tbc.

Data published Sinha, Hughes, et, al Nature tbc. 2- colour microarray comparing to common background pool (containing all life cycle stages). Replicates of different life cycle stages of gametocyte non-producer lines and wild tye (WT) parental control lines
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.
Project description:Previously published data indicated that PgCHT2 forms a high molecular weight (HMW), reduction-sensitive complex; data suggested that the binding partner is the ookinete-produced von Willebrand A-domain-containing protein, WARP. To test the hypothesis that transgenic P.berghei ookinete-produced PfCHT1 could form a high molecular homo-multimer or, alternatively, could interact with P. berghei ookinete-produced proteins to produce a HMW hetero-multimer, we created a chimeric P. berghei parasites expressing PfCHT1 to replace PbCHT1, allowing production of large numbers of PfCHT1-expressing ookinetes.Mass spectrometry analysis was carried out on the chitin affinity pulled down proteins from the Pb-PfCHT1(r) ookinete culture supernatant.
