Malaria

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...

Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique helps...

Area of Science:

Systems biology
Genomics
Protein function prediction

Background:

Inferring functions for uncharacterized proteins is a key challenge in genomics.
This is particularly difficult in pathogens like malaria parasites.

Purpose of the Study:

To predict functions of uncharacterized proteins in malaria parasites.
To leverage comparative expression analysis and literature mining for functional inference.

Main Methods:

Comparative expression analysis across Plasmodium falciparum and Plasmodium yoelii life cycle stages.
Analysis of coordinated transcription patterns in human and yeast expression data for orthologous genes.
Literature mining to identify potential roles of parasite-specific genes.

Main Results:

Type II fatty acid biosynthesis genes are upregulated in liver and insect stages.
Coordinated transcription patterns of uncharacterized genes across species suggest conserved functions.
Probabilistic models predict functions for 926 uncharacterized malaria genes.

Conclusions:

Malaria parasites can serve as model systems for studying human processes.
Functional predictions provide a foundation for understanding transcriptional regulation in malaria parasites.
This work aids in identifying potential drug targets and understanding parasite biology.
