Whole-mount in situ hybridization for analysis of gene expression during Aedes aegypti development.

Blood-feeding mosquitoes, including the dengue and yellow fever vector Aedes aegypti, transmit many of the world's deadliest diseases. Such diseases have resurged in developing countries and pose clear threats for epidemic outbreaks in developed countries. Recent mosquito genome projects have stimulated interest in the potential for arthropod-borne disease control by genetic manipulation of vector insects, and genes that regulate development are of particular interest.

Induction of cellular growth by the axon guidance regulators netrin A and semaphorin-1a.

Although neurite outgrowth has been linked to axon guidance regulators, the effects of guidance molecules on cellular growth are not well understood. Use of the Drosophila wing imaginal disc, an epithelial tissue and a well-characterized system for analysis of cellular growth regulation, permits analysis of the impacts of guidance molecules on cellular growth in a setting in which axon guidance is not a confounding factor. In this investigation, the impacts of Netrin A (NetA) and Semaphorin-1a (Sema1a) signaling on cellular growth are examined during wing development.
