Abstract
The N6-methyladenosine (m6A) modification of RNA has been reported to affect viral infections. Studies have confirmed the role of m6A in replication of several vector-borne flaviviruses, including dengue virus (DENV), in mammalian cells. Here, we explored the role of m6A in DENV replication in the mosquito Aedes aegypti Aag2 cell line. We first determined the presence of m6A on the RNAs from mosquito cells and using methylated RNA immunoprecipitation and sequencing (MeRIP-Seq) identified m6A modification of the mosquito transcriptome and those that changed upon DENV infection. Depletion of m6A methyltransferases and the m6A binding protein YTHDF3 RNAs decreased the replication of DENV. In particular, we found that the Ae. aegypti ubiquitin carrier protein 9 (Ubc9) is m6A modified and its expression increases after DENV infection. Silencing of the gene and ectopic expression of Ubc9 led to reduced and increased DENV replication, respectively. The abundance of Ubc9 mRNA and its stability were reduced with the inhibition of m6A modification, implying that m6A modification of Ubc9 might enhance expression of the gene. We also show that the genome of DENV is m6A modified at five sites in mosquito cells. Altogether, this work reveals the involvement of m6A modification in Ae. aegypti-DENV interaction. Analysis of m6A RNA modifications in the mosquito transcriptome and their changes upon dengue virus infection provides insight into the role of epigenetics in regulating viral replication in mosquitoes.

Abstract
Dengue remains one of the most serious and widespread mosquito-borne viral infections in human beings, with serious health problems or even death. About 50 to 100 million people are newly infected annually, with almost 2.5 billion people living at risk and resulting in 20,000 deaths. Dengue virus infection is especially transmitted through bites of Aedes mosquitos, hugely spread in tropical and subtropical environments, mostly found in urban and semiurban areas. Unfortunately, there is no particular therapeutic approach, but prevention, adequate consciousness, detection at earlier stage of viral infection, and appropriate medical care can lower the fatality rates. This review offers a comprehensive view of production, transmission, pathogenesis, and control measures of the dengue virus and its vectors.
