Gene Expression
Nebulas
Gene Expression NebulasSummary: We present evidence that (1) viral respiratory infections are potential mechanisms of ACE2 overexpression in patients with asthma and (2) ACE activation regulates multiple cytokine anti-viral responses that could explain a mechanism for cytokine surge and associated tissue damage. These results suggest that the recent finding of severe COVID-19 in asthma patients with recent exacerbations may be attributable to synergistic biomolecular interactions with viral co-infections.
Overall Design: In a paired design experiments across discovery and validation cohorts of in asthmatic patients the biological replicates treated with RVA and RVC were compared to non-treated ones.

| Growth Protocol: | We developed well-differentiated ciliated air-liquid interface (ALI) cultures from nasal tissues biopsied from thirty adults with physician-diagnosed asthma. |
| Treatment Protocol: | - |
| Extract Protocol: | RNA was extracted from whole-cell lysates, mapped to the UCSC transcript set using Bowtie2 (v2.1.0) and the gene expression level was estimated using standard techniques. |
| Library Construction Protocol: | Libraries for RNA-Seq were prepared with Kapa Stranded mRNA. The workflow consisted of mRNA enrichment, cDNA generation, and end repair to generate blunt ends, A-tailing, adaptor ligation and PCR amplification. Different adaptors were used for multiplexing samples in one lane. |
