Unfortunately, artemisinin-based combination therapies (ACTs), recently adopted as our last resort in combating malaria infection, are already challenged by ACT-resistant strains detected in south-east Asia. With the spread of parasite resistance to all current antimalarial drugs, successful control and eradication will only be achieved if new efficient tools and cost-effective

antimalarial strategies are developed. When the near-completed sequence of the genome of the human malaria parasite P. falciparum was first published (1), the scientific community predicted that it would accelerate the discovery of new drug targets and vaccine strategies. Almost a decade later, this is still PDGFR inhibitor a work-in-progress. The genome sequence of the malaria Palbociclib parasite has nonetheless provided the foundation for modern biomedical research. The goal is now to transform our increasing knowledge of the parasite’s biology into actual improvements of human health. Such achievement requires an integrated understanding of both the pathogen’s and the host’s responses to infection. In this review, we present an overview of the P. falciparum genome as well as recent advances in genomics and systems biology that have led to major improvements in the understanding of the pathogen. We discuss the impact of these approaches on the development

of new therapeutic strategies as well as exploring the long-term goal of global malaria eradication. The first draft of the P. falciparum genome was published after 7 years of international effort. The genome was sequenced using the Sanger method and chromosome shotgun strategy (1). The size of the genome was initially estimated at 22·8 Mb separated into 14 chromosomes and 5300 protein-encoding predicted genes. In addition to its nuclear genome, the parasite contains

6- and 35-kb circular DNA found in its mitochondria and plant-related apicoplast, respectively. Today, the P. falciparum genome remains to be the most AT-rich genome. The overall (A + T) composition is 80·6% and can rise to 95% in introns and intergenic regions. After almost 9 years of coordinated genome MRIP curation efforts, the complete genome sequence is defined as haploid and 23·26 Mb in size. It contains 6372 genes and 5524 protein-coding genes (genome version: 06-01-2010, http://plasmodb.org/plasmo/). Approximately half of these genes have no detected sequence homology with any other model organism. Despite recent access to comparative and functional genomics studies and the completion of genome sequencing of more than eight Plasmodium species, the cellular function of most of the parasite genes remains obscure. Over the past few years, extensive resequencing efforts have been successfully undertaken to identify genes and genetic traits associated with parasite’s drug resistance and severity of the clinical outcomes. Initial sequencing surveys of genetic variation across the P.
