Project description:Subjects are children from Kilifi District Hospital, Kenya, recruited in 2001 malaria season. total RNA extracted from PaxGene tubes, total RNA and Stratagene Universal reference RNA underwent linear amplification (Message Amp, Ambion). Amplified RNA directly labelled Cy5 and Cy3 and hybridised to 'lymphochip' arrays (print run - lc36n). Scanned on Axon 4000B scanner using GenePix 4.0 software. Clinical sample ID provided in 'Disease State Description' corresponds with Sample ID in Table 1 "Clinical Information for the micro-array samples" in the associated publication.

Project description:<p>The malaria parasite life cycle includes asexual replication in human blood, with a proportion of parasites differentiating to gametocytes required for transmission to mosquitoes. Commitment to differentiate into gametocytes, which is marked by activation of the parasite transcription factor <em>ap2-g</em> , is known to be influenced by host factors but a comprehensive model remains uncertain. Here we analyze data from 828 children in Kilifi, Kenya with severe, uncomplicated, and asymptomatic malaria infection over 18 years of falling malaria transmission. We examine markers of host immunity and metabolism, and markers of parasite growth and transmission investment. We find that inflammatory responses and reduced plasma lysophosphatidylcholine levels are associated with markers of increased investment in parasite sexual reproduction (i.e., transmission investment) and reduced growth (i.e., asexual replication). This association becomes stronger with falling transmission and suggests that parasites can rapidly respond to the within-host environment, which in turn is subject to changing transmission.</p>
Project description:We performed shallow whole genome sequencing (WGS) on circulating free (cf)DNA extracted from plasma or cerebrospinal fluid (CSF), and shallow WGS on the tissue DNA extracted from the biopsy in order to evaluate the correlation between the two biomaterials. After library construction and sequencing (Hiseq3000 or Ion Proton), copy number variations were called with WisecondorX.
