Developmental time course of gene expression in Anopheles gambiae embryo

ABSTRACT: In order to examine the gene expression in the course of mosquito embryogenesis, microarray assays were performed on staged A. gambiae embryos, from fertilization to 52 hours of development (which is close to hatching at ~50 hours post-fertilization). RNA was extracted from staged embryos roughly every three hours after fertilization, and then hybridized to the A. gambiae transcriptome microarray. Keywords: time-course

Gene expression in the embryonic serosa of Anopheles gambiae

Project description:Whole-genome transcriptome assays were performed with isolated serosa from A. gambiae embryos. These assays identified a large number of genes implicated in the production of the larval cuticle. In D. melanogaster, these genes are activated just once during embryogenesis, during late stages where they are used for the production of the larval cuticle. Evidence is presented that the serosal cells secrete a dedicated serosal cuticle, which protects A. gambiae embryos from desiccation.

Transcriptome analysis of virgin and mated Anopheles gambiae and Anopheles albimanus

Project description:We custom-built a bioinformatics pipeline to search for 20E-modifying enzymes in the accessory glands of Anopheles gambiae males, searching for ecdysteroid kinases (EcK), ecdysone oxidases (EO), and ecdysteroid-phosphate phosphatases (EPP). To this end, we generated RNAseq datasets of different An. gambiae tissues dissected from virgin and mated females and males, and produced similar datasets for Anopheles albimanus, a South American species that does not synthetize and transfer ecdysteroids during mating. These analyses led to the identification of one candidate EPP and two potential EcKs (EcK1 and EcK2), which we demonstrated are involved in the activity of a male-specific oxidized ecdysteroid (3D20E). We further determined that 3D20E is specifically produced by the An. gambiae male accessory glands and is transferred to females during copulation, where it triggers a series of post-mating responses.

Anopheles gambiae genome-wide gene expression in response to bloodmeal

Project description:With their genome sequenced, Anopheles gambiae mosquitoes now serve as a powerful tool for basic research in comparative, evolutionary and developmental biology. The knowledge generated by these studies is expected to reveal molecular targets for novel vector control and pathogen transmission blocking strategies. Comparisons of gene-expression profiles between adult male and nonblood-fed female Anopheles gambiae mosquitoes revealed that roughly 22% of the genes showed sex-dependent regulation. Blood-fed females switch the majority of their metabolism to blood digestion and egg formation within 3 h after the meal is ingested, in detriment to other activities such as flight and response to environment stimuli. Changes in gene expression are most evident during the first, second and third days after a blood meal, when as many as 50% of all genes showed significant variation in transcript accumulation. After laying the first cluster of eggs (between 72 and 96 h after the blood meal), mosquitoes return to a nongonotrophic stage, similar but not identical to that of 3-dayold nonblood-fed females. Ageing and/or the nutritional state of mosquitoes at 15 days after a blood meal is reflected by the down-regulation of 5% of all genes. A full description of the large number of genes regulated at each analysed time point and each biochemical pathway or biological processes in which they are involved is not possible within the scope of this contribution. Therefore, we present descriptions of groups of genes displaying major differences in transcript accumulation during the adult mosquito life. However, a publicly available searchable database (Anopheles gambiae Gene Expression Database at UC Irvine) has been made available so that detailed analyses of specific groups of genes based on their descriptions, functions or levels of gene expression variation can be performed by interested investigators according to their needs.
