Background

The concurrent Zika Virus (ZIKV) outbreaks in the United States and Northeast Brazil have evoked global surveillance. Zika infection has been correlated with severe clinical symptoms, such as microcephaly, Guillain-Barré syndrome, and other congenital brain abnormalities. Recent data suggest that ZIKV predominantly targets neural progenitor cells leading to neurological impairment. Despite the clinical evidence, detailed experimental mechanism of ZIKV neurotropic pathogenesis has not been fully understood yet. Here we hypothesized that ZIKV produces miRNAs, which target essential host genes involved in various cellular pathways facilitating their survival through immune evasion and progression of disease during brain development.

Methods

From genome sequence information using several bioinformatic tools, we predicted pri-miRNAs, pre-miRNAs, and finally the mature miRNAs produced by ZIKV. We also identified their target genes and performed functional enrichment analysis to identify the biological processes associated with these genes. Finally, we analyzed a publicly available RNA-seq data set to determine the altered expression level of the targeted genes.

Results

From ZIKV genome sequence, we identified and validated 47 putative novel miRNAs. Functional enrichment of the targeted genes demonstrates the involvement of various biological pathways regulating cellular signaling, neurological functions, cancer, and fetal development. The expression analysis of these genes showed that ZIKV-produced miRNAs downregulate the key genes involved in these pathways, which in turn may lead to impaired brain development.

Conclusions

Our finding proposes novel ZIKV miRNAs and their targets, which upon experimental validation could help developing new therapeutics to combat ZIKV infection and minimize ZIKV-mediated pathologies.
