Computational analysis of functionally related genes in mouse response to Plasmodium chabaudi

According to the World Health Organization (WHO), over 1-3 million children under the age of five die due to malaria each year. The aim of this project is to increase our understanding of the
Plasmodium

chabaudi
parasite and of its interactions with the mammalian host using a computational approach. This is achieved by applying a time-series clustering algorithm to a publicly available short time-series gene expression data representing two disease states (
P.

chabaudi
infected and non infected), two genders (male and female), two protocols (intact and gonadectomized), and four time points (0, 3, 7, and 14 days after inoculation) of
Mus

musculus
(mouse) response to
P.

chabaudi
infection. Results obtained provide a rigorous statistical explanation to the fact that intact males were more likely than intact females to die following
P.

chabaudi
infection on one hand, and on the other hand, gonadectomy of male and female mice altered these sex-associated differences. These findings may suggest that sex steroid hormone modulates immune responses to pathogen attacks.
