Transcription inhibition in Aedes Albopictus C6/36 cells

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.

wMelpop strain of Wolbachia infection of Aedes albopictus mosquito C6/36 cells modulates dengue virus-induced host cellular transcripts and induces critical sequence alterations in dengue viral genome

Project description:The dengue virus (DENV) cause frequent epidemics infecting ~390 million people annually in over 100 countries. There are no approved vaccines or antiviral drugs for treatment of infected patients. However, there is a novel approach to control transmission of DENV by the mosquito vectors, Aedes aegypti and Ae. albopictus, using Wolbachia symbiont. The wMelPop strain of Wolbachia suppresses DENV transmission and shortens the mosquito life span. However, the underlying mechanism is poorly understood. To clarify this mechanism, either naïve Ae. albopictus (C6/36) or wMelPop-C6/36 cells were infected with DENV2. Analysis of host transcript profiles by RNAseq revealed that the presence of wMelPop had profound effects on mosquito host cell transcription in response to DENV2 infection. The viral RNA evolved from wMelPop-C6/36 contained low frequency mutations (~25%) within the coding region of transmembrane domain-1 (TMD1) of E protein. Mutations with >97 % frequencies were distributed within other regions of E, NS5 RNA-dependent RNA polymerase (NS5POL) domain, the TMDs of NS2A, NS2B, and NS4B. Moreover, while DENV2-infected naïve C6/36 cells showed syncytia formation, DENV2-infected wMelPop-C6/36 cells did not. The Wolbachia-induced mutant DENV2 can readily infect and replicate in naïve C6/36 cells; whereas, in the mutant DENV2- infected BHK-21 or Vero cells, the virus replication was delayed. In LLC-MK2 cells, the mutant failed to produce plaques. Additionally, in BHK-21 cells, many mutations in the viral genome reverted to WT and compensatory mutations in NS3 gene appeared. Our results suggest that wMelPop impacts significantly the interactions of DENV2 with mosquito and mammalian host cells.

Quantitative proteomic analysis of ZIKV infected C6/36 cells

Project description:An iTRAQ-based quantitative proteomic analysis of ZIKV infected Aedes albopictus C6/36 cells was performed to investigate host proteins involved in ZIKV infection process. A total of 3,544 host proteins were quantified, with 200 being differentially regulated. Bioinformatics analysis on regulated host proteins highlights several ZIKV infection regulated biological processes.
