Functional analysis of AeSCP-2 using gene expression knockdown in the yellow fever mosquito, Aedes aegypti.
The effect of gene expression knockdown was used to study the function of the sterol carrier protein-2 (AeSCP-2) in the yellow fever mosquito, Aedes aegypti. Injection of small double stranded AeSCP-2 RNAs into mosquito larvae resulted in the knockdown of gene products. The lack of AeSCP-2 in larvae coincided with a reduction in accumulated cholesterol in pupae, supporting the hypothesis that AeSCP-2 may be involved in cholesterol uptake in mosquito larvae. Knockdown of AeSCP-2 caused a high mortality rate in developing adult and reduced egg viability. Results from this study indicate that AeSCP-2 is important for adult development and for the viability of the eggs.
