Project description:Aedes albopictus shows a rapid global expansion and dramatic vectorial capacity for various arboviruses. Mosquitoes display distinct sexual dimorphisms，only adult females consume blood meals to complete ovarian follicle development. Therefore, cyclic reproduction in female mosquitoes serves as a foundation for the transmission of numerous disease-causing pathogens. Aedes have an expansion of the piRNA biogenesis genes, indicated that piRNA may play multiple functional roles in mosquitoes. Although the antiviral function of piRNA pathway in mosquitoes has been extensively studied, the role of piRNAs in mosquito reproduction remain to be further understood. In the present study, we first profiled the characteristics of sex-biased piRNAs in adult Ae.albopictus. Then, we identified a female biased piRNA (Aalpi18529) in adult females, that was highly expressed in ovaries at blood feeding-dependent termination, and depended on PIWI5 and ago3 mediated biogenesis. Aalpi18529 overexpression suppressed ovarian development, and reduced fertility and fecundity in adult females post-bloodmeal. Furthermore, we demonstrated that Aalpi18529 can effectively repress its direct target, growth arrest and DNA-damage-inducible protein 45a (GADD45A), and eventually regulates ovarian development via the Gadd45a-mediated JNK-dependent nurse cell apoptosis pathway. Our study is the first to report an endogenous piRNA, which trigger silencing of an important protein-coding gene by posttranscriptional regulation in mosquitoes, expanding our current understanding of the important and multiple roles of piRNAs in biological processes in Ae. albopictus.

Project description:Aedes albopictus shows a rapid global expansion and dramatic vectorial capacity for various arboviruses, thus posing a severe threat to global health. Although many noncoding RNAs have been confirmed to play functional roles in various biological processes in Ae. albopictus, the roles of circRNA remain a mystery. In the present study, we first performed high-throughput circRNA sequencing in Ae. albopictus. Then, we identified a cysteine desulfurase (CsdA) superfamily gene-originated circRNA, namely, aal-circRNA-407, which was the third most abundant circRNA in adult females and displayed a fat body highly expressed manifestation and blood feeding-dependent onset. siRNA-mediated knockdown of circRNA-407 resulted in a decrease in the number of developing follicles and a reduction in follicle size post blood meal. Furthermore, we demonstrated that circRNA-407 can act as a sponge of aal-miR-9a-5p to promote the expression of its target gene Foxl and eventually regulate ovarian development. Our study is the first to report a functional circRNA in mosquitoes, expanding our current understanding of important biological roles in mosquitoes and providing an alternative genetic strategy for mosquito control.

Project description:To determine codon optimality in Aedes Albopictus C6/36 cells, we blocked transcription using three independent transcription inhibitors (5,6-Dichlorobenzimidazole 1-β-D-ribofuranoside (DRB), Flavopiridol and Triptolide) and measured the RNA level at 6 hours post treatment using RNA-seq.

Project description:Certain strains of the intracellular endosymbiont Wolbachia can strongly inhibit or block the transmission of viruses such as dengue by Aedes mosquitoes, and the mechanisms responsible are still not well understood. Direct infusion and liquid chromatography FT-ICR mass spectrometry based lipidomicse DIMS and LCMS analyses were conducted using Aedes albopictus Aa23 cells that were infected with the wMel and wMelPop strains of Wolbachia compared to uninfected cells. Substantial shifts in the cellular lipid profile were apparent in the presence of Wolbachia. Most significantly, sphingolipids were depleted across all classes, and some reduction in diacylglyerol fatty acids and phosphatidylcholines was also observed. These lipid classes have previously been shown to be selectively enriched in DENV-infected mosquito cells, suggesting that Wolbachia may produce a cellular lipid environment that is antagonistic to viral replication. The data improve understanding of the intracellular interactions between Wolbachia and mosquitoes.

Project description:The impact of global climate change on the transmission dynamics of infectious diseases is the subject of extensive debate. The transmission of mosquito-borne viral diseases is particularly complex, with climatic variables directly affecting many parameters associated with the prevalence of disease vectors. While evidence shows that warmer temperatures often decrease the extrinsic incubation period of an arthropod-borne virus (arbovirus), exposure to cooler temperatures often predisposes disease vector mosquitoes to higher infection rates. RNA interference pathways are essential to antiviral immunity in the mosquito; however, few experiments have explored the effects of temperature on the RNAi machinery. Total small RNAs (miRNAs, siRNAs, piRNAs, etc.) were isolated and sequenced from the heads of sensor strain Aedes aegypti mosquitoes, or from the whole bodies of CHIKV-infected Aedes albopictus mosquitoes 8 hours post infection. Mosquitoes were grown at 18C or 28C in replicates of 1 (Ae. aegypti) or 3 (Ae. albopictus).
