A systematic approach to understand the mechanism of action of the bisthiazolium compound T4 on the human malaria parasite, Plasmodium falciparum (2008)

Le Roch, Karine G, Johnson, Jeffrey R, Ahiboh, Hugues, Chung, Duk-Won D, Prudhomme, Jacques, Plouffe, David, ...

Abstract Background In recent years, a major increase in the occurrence of drug resistant falciparum malaria has been reported. Choline analogs, such as the bisthiazolium T4, represent a novel class...

A Systematic Map of Genetic Variation in Plasmodium falciparum (2006)

Claire Kidgell, Sarah K. Volkman, Johanna Daily, Justin O. Borevitz, David Plouffe, Yingyao Zhou, ...

Discovering novel genes involved in immune evasion and drug resistance in the human malaria parasite, Plasmodium falciparum, is of critical importance to global health. Such knowledge may assist in...

An integrated view of the chemistry and mineralogy of Martian soils. (2006)

Yen, Albert S., Gellert, Ralf, Schroder, Christian, Morris, Richard V., Bell, James F. III, Knudson, Amy T., ...

The mineralogical and elemental compositions of the martian soil are indicators of chemical and physical weathering processes. Using data from the Mars Exploration Rovers, we show that bright dust...

Global Analysis of Transcript and Protein Levels Across the Plasmodium falciparum Life Cycle (2006)

To investigate the role of post-transcriptional controls in the regulation of protein expression for the malaria parasite, Plasmodium falciparum, we have compared mRNA transcript and protein...

Proteomics in Malaria (2006)

Johnson, Jeffrey R., Florens, Laurence, Carucci, Daniel J.

The recent completion of human, Anopheles gambiae, and Plasmodium falciparum genomes relevant to the study of human malaria allows the application of modern proteomic technologies to complement...

A Plasmodium Gene Family Encoding Maurer's Cleft Membrane Proteins: Structural Properties and Expression Profiling (2006)

Sam-Yellowe, Tobili Y., Florens, Laurence, Johnson, Jeffrey R., Wang, Tongmin, Drazba, Judith A., Le Roch, Karine G., ...

Upon invasion of the erythrocyte cell, the malaria parasite remodels its environment; in particular, it establishes a complex membrane network, which connects the parasitophorous vacuole to the host...
