Discovery of Telomere Repeat-binding Zinc finger protein in the malaria parasite Plasmodium falciparum

Project description:ChIP-seq experiments were performed for the putative Telomere Repeat-binding Zinc finger protein (PfTRZ) in the malaria parasite Plasmodium falciparum strain 3D7. The gene encoding this factor (PF3D7_1209300) was endogenously tagged with either a GFP- or a 3xHA-tag and these transgenic parasite lines were used in ChIP-sequencing experiments. Sequencing of the ChIP and input libraries showed enrichment of PfTRZ at all telomere-repeat containing chromosome ends (reference genome Plasmodium falciparum 3D7 from PlasmoDB version 6.1) as well as in all upsB var promoters.In addition,PfTRZ was enriched at seven additional, intra-chromosomal sites and called in the PfTRZ-HA ChIP-seq only.

Plasmodium falciparum 3D7 parasites were generated with -GFP or -3xHA C-terminal tagged TRF (PF3D7_1209300). Nuclei were isolated from formaldehyde cross-linked schizont-stage transgenic parasites and used to prepare chromatin. Chromatin immunoprecipitations were performed using mouse anti-GFP (Roche Diagnostics, #11814460001) or rat anti-HA 3F10 (Roche Diagnostics, #12158167001). Sequencing libraries were prepared according to a Plasmodium-optimized library preparation procedure including KAPA polymerase-mediated PCR amplification.

Submicroscopic and asymptomatic Plasmodium falciparum and P. vivax infections are common in western Thailand - molecular and serological evidence

Project description:Background: Malaria is a public health problem in parts of Thailand, where Plasmodium falciparum and Plasmodium vivax are the main causes of infection. In the northwestern border province of Tak parasite prevalence is now estimated to be less than 1% by microscopy. Nonetheless, microscopy is insensitive at low-level parasitaemia. The objective of this study was to assess the current epidemiology of falciparum and vivax malaria in Tak using molecular methods to detect exposure to and infection with parasites; in particular, the prevalence of asymptomatic infections and infections with submicroscopic parasite levels. Methods: Three-hundred microlitres of whole blood from finger-prick were collected into capillary tubes from residents of a sentinel village and from patients at a malaria clinic. Pelleted cellular fractions were screened by quantitative PCR to determine parasite prevalence, while plasma was probed on a protein microarray displaying hundreds of P. falciparum and P. vivax proteins to obtain antibody response profiles in those individuals. Results: Of 219 samples from the village, qPCR detected 25 (11.4%) Plasmodium sp. infections, of which 92% were asymptomatic and 100% were submicroscopic. Of 61 samples from the clinic patients, 27 (44.3%) were positive by qPCR, of which 25.9% had submicroscopic parasite levels. Cryptic mixed infections, misdiagnosed as single-species infections by microscopy, were found in 7 (25.9%) malaria patients. All sample donors, parasitaemic and non-parasitaemic alike, had serological evidence of parasite exposure, with 100% seropositivity to at least 54 antigens. Antigens significantly associated with asymptomatic infections were P. falciparum MSP2, DnaJ protein, putative E1E2 ATPase, and three others.

Capturing the dynamic RNA landscape of the malaria parasite P. falciparum

Project description:To date, total mRNA analysis throughout intraerythrocytic development of the malaria parasite, Plasmodium falciparum, has only revealed abundance profiles of each gene at a given time. Here, we establish a new methodology in Plasmodium falciparum that enables biosynthetic labeleing and capture of sub-population mRNA. As a proof of principle for this novel method, we examine the mRNA dynamics of early gametocyte commitment.

The P. falciparum orthologue of Male Development Protein 3 is a Male-associated regulator of translation initiation or enhancement [CLIP-Seq]

Project description:Sex determination and development of Plasmodium gametocytes is critical to the transmission of malaria parasites and involves a complex interplay of multiple molecular factors. Here, we characterized the P. falciparum gene syntenic to P. berghei MD3- pf3d7_0315600. This protein contains a non-classical CCCH zinc-finger domain and Lysine-Proline rich domain associated with ribosome receptors, suggesting a role in mRNA regulation. We investigated the function of PfMD3-3xHA using in vivo using crosslinked RNA-Protein interaction capture followed by RNA-sequencing (CLIP-seq) to determine its RNA targets in both early (stage II) and late (stage IV-V) development of gametocytes. We found that these bound mRNA targets show decreased protein levels in a genetic knockout of PfMD3, suggesting a role for PfMD3 in translational processing. We then propose that PfMD3 functions as a Male Associated Regulator of Translation Initiation or Enhancement (MARTIE) in the human malaria parasite P. falciparum.
