Abstract
Aim: To investigate the mRNAs and noncoding RNAs (ncRNAs) expression in astrocytes upon meningitic-Escherichia coli infection. Materials & methods: The transcription of mRNAs and ncRNAs were fully investigated and profiled by whole transcriptome sequencing and bioinformatic approaches. Whole transcriptome differences between the infected astrocytes and brain microvascular endothelial cells were further compared and characterized. Results: A total of2045 mRNAs, 74 long noncoding RNAs, 27 miRNAs and 418 circular RNAs were differentially transcribed in astrocytes upon infection. Competing endogenous RNAs regulatory networks were constructed and preliminary validated. Transcriptomic differences between astrocyte and brain microvascular endothelial cells revealed the cell-specific responses against the infection. Conclusion: Our study comprehensively characterized the ncRNAs and mRNAs profiles in astrocytes upon meningitic-E. coli infection, which will facilitate future functional studies.
