Project description:The transcriptional profile of pyrethroid resistant Anopheles arabiensis from Zanzibar. Anopheles arabiensis from Pemba Island, exposed (Survivors) and non-exposed (Pemba) to a discriminating dose of the pyrethroid lambda-cyhalothrin were compared to two insecticide susceptible strains from Zanzibar island (Unguja) and Dar es Salaam (Dar).
Project description:The transcriptional profile of Anopheles arabiensis collected from a pyrethroid resistant area on Pemba Island collected in 2011 was compared to that of a lab susceptible colony of Anopheles arabiensis (MOZ).
Project description:Anopheles arabiensis from Jinja, Uganda resistant to permethrin (1hr exposure) were compared to sympatric controls and two pyrethroid susceptible colonies of An. arabiensis (Moz and Dongola)
Project description:Illumina HiSeq 2500 technology was used to sequence the transcriptome of three Ethiopian field populations of An. arabiensis (Asendabo (ASN), Chewaka (CHW) and Tolay (TOL)) and two An. arabiensis strains (Sekoru (SEK, from Ethiopia) and Moz (MOZ, from Mozambique)). Both ASN, CHW and TOL were previously shown to be resistant against delamethrin and DDT, while the two An. arabiensis strains (SEK and MOZ) were both susceptible to deltamethrin and DDT (Alemayehu et al. 2017, DOI: 10.1186/s13071-017-2342-y; Witzig et al. 2013, DOI: 10.1038/hdy.2012.112). Differentially expressed genes (absolute fold change (FC) ≥ 2 and Benjamini-Hochberg adjusted p-value < 0.05) were determined between each insecticide resistant field population (ASN, CHW or TOL) and one of the insecticide susceptible strains (SEK or MOZ).
Project description:We characterize the epigenome of the human malaria vector Anopheles gambiae in midgut cells by mapping the distribution and levels of two post-translational histone modifications, H3K27ac and H3K27me3. These histone profiles were then correlated with levels of gene expression obtained by RNA-seq.
