Project description:<p>The genomes of positive-sense (+) single-stranded RNA (ssRNA) viruses are believed to be subjected to a wide range of RNA modifications. In this study, we focused on the chikungunya virus (CHIKV) as a model (+) ssRNA virus to study the landscape of viral RNA modification in infected human cells. Among the 32 distinct RNA modifications analyzed by mass spectrometry, inosine was found enriched in the genomic CHIKV RNA. However, orthogonal validation by Illumina RNA-seq analyses did not identify any inosine modification along the CHIKV RNA genome. Moreover, CHIKV infection did not alter the expression of ADAR1 isoforms, the enzymes that catalyze the adenosine to inosine conversion. Together, this study highlights the importance of a multidisciplinary approach to assess the presence of RNA</p><p>modifications in viral RNA genomes.</p>
Project description:We report RNA-seq analysis of Vehicle control, cAIMP, or scleroglucan treated human fibroblasts under uninfected (mock) and Chikungunya virus infected conditions.
Project description:In this study, we aim to identify common host genes involved in pathogenesis of different Chikungunya virus strains as an attempt to recognize probable antiviral targets. We have compared the host gene regulation after infection of monkey kidney cell line (Vero) with two different wild type CHIKV strains i.e. S 27 (human, ECSA), and DRDE-06 (human, ECSA). Vero cells were mock infected or infected with two Chikungunya virus strains (S 27 and DRDE-06) and harvested at 8hpi and 18hpi. The total RNA was extracted and microarray was done using Agilent protocol.
Project description:Chikungunya virus (CHIKV) infection is characterized by alterations in gene expression profile on host cells that consequently lead to an immune response. Here, we used RNA sequencing to analyze the mRNA expression profile in human monocyte-derived macrophages (MDMs) infected with a Colombian clinical isolate of CHIKV at 6 and 24 hpi. analyze the mRNA expression profile in the human monocyte-derived macrophages infected at 6 and 24 hrs with a Colombian clinical isolate of Chikungunya virus.
Project description:Human monocyte-derived macrophage cells were infected with Chikungunya virus (CHIKV) to identify and quantify intracellular transcriptional changes that contribute to the host response to infection with CHIKV. RNA was collected from these cells at 8 and 24 hours post-infection (hpi) and were compared to mock-infected cells. The RNAseq data was then analyzed to determine the genes, functions, and signaling pathways that were significantly affected in an effort to predict existing drugs that could be repurposed as potential therapeutics for CHIKV.
