Project description:During red-blood-cell-stage infection of Plasmodium falciparum, the parasite undergoes repeated rounds of replication, egress, and invasion. Erythrocyte invasion involves specific interactions between host cell receptors and parasite ligands and coordinated expression of genes specific to this step of the life cycle. We show that a parasite-specific bromodomain protein, PfBDP1, binds to chromatin at transcriptional start sites of invasion-related genes and directly controls their expression. Conditional PfBDP1 knockdown causes a dramatic defect in parasite invasion and growth and results in transcriptional downregulation of multiple invasion-related genes at a time point critical for invasion. Conversely, PfBDP1 overexpression enhances expression of these same invasion-related genes. PfBDP1 binds to acetylated histone H3 and a second bromodomain protein, PfBDP2, suggesting a potential mechanism for gene recognition and control. Collectively, these findings show that PfBDP1 critically coordinates expression of invasion genes and indicate that targeting PfBDP1 could be an invaluable tool in malaria eradication.

Project description:We compared transcript levels at several points along the asexual blood cycle between 21 P. falciparum lines. These 21 parasite lines are organized in 4 sets of parasite lines, with all parasite lines within a set sharing a clonal origin. We compared transcript levels within each set. We also performed comparative genome hybridization (CGH) for all 21 parasite lines.

Project description:Purpose: this study is to analyze the change of overal transcriptome after disruption of DNA methyltransferase (DNMT) in Plasmodium falciparum. Methods: In this study, the transcriptomes of a PfDNMT gene knockout (KO) parasite line with its wildtype control, its complementation (adding back the DNMT expression by episomal expression of DNMT in the DNMT KO parasite), and overexpression (episomal expression of DNMT in the wildtype parasite) were analyzed by RNAseq. Total RNA were harvested from the asexual parasites at three developmental stages (ring, trophozoite, and schizont) using the Quick-RNA MiniPrep kit (Zymo Research). RNA sequencing libraries were prepared using the KAPA stranded RNA-seq library preparation kit (Roche) with 500 ng RNA from each sample. Illumina adapter sequence removal and quality trimming of reads were performed using Trimmomatic. Only reads that had a minimum length of 50 base pairs were retained. Reads were then mapped to the P. falciparum 3D7 strain reference genome with HISAT2. Results: Using an optimized data analysis workflow, we mapped about 5 million sequence reads per sample to the malaria parasite genome (pf3D7_V3.0.) and identified 5712 transcripts with high mapping rate at the range between 80% and 95. PfDNMT KO profoundly disturbed the global transcription pattern,especially at trophozoite stage, causing 1732 (30.3%) genes to be differentially expressed at trophozoite.Complementation restored the expression pattern and overexpression of PfDNMT caused nearly 2000 gene ro be differentially expressed at schizont stage. Conclusions: Collectively, transcriptomic analysis of DNMT KO, complemetation and overexpression shows PfDNMT plays important role in gene regulation.

Project description:Trichinellosis of human and other mammals was caused through the ingestion of the parasite，Trichinella spiralis，contaminated meat. It is a typical zoonotic disease that affects more than 10 million people world-wide. Parasites of Trichinella genus are unique intracellular pathogens. Adult Trichinella parasites directly release newborn larvae which invade striated muscle cells and causes diseases. In this study, we profiled the global transcriptome in the three developmental stages of T. spiralis. The transcriptomic analysis revealed the global gene expression patterns from newborn larval stage through muscle larval stage to adults. Thousands of genes with stage-specific transcriptional patterns were described and novel genes involving host-parasite interaction were identified. More than 45% of the protein-coding genes showed evidence of transcription from both sense and antisense strands which suggests the importance of RNA-mediated gene regulation in the parasite. This study presents a first deep analysis of the transcriptome of T. spiralis, providing insight information of the parasite biology.
