Fig. 8
Comparative analysis of miRNA expression levels between our nasal swab (NS) samples and those obtained from various studies on blood. We examined the expression levels of fourteen identified miRNAs showing > 2-fold change in expression from our study in comparison to samples from blood, including WBC, plasma, and serum. Red boxes denote miRNAs that were upregulated, while green boxes denote those that were downregulated following COVID-19 infection. The miRNAs highlighted in blue showed the same expression profile in our nasal swab samples as those observed in the WBCs, plasma, or serum reported from other studies, while the miRNA in orange was the most consistently dysregulated miRNA reported in most studies listed here. This is contrary to the profile of serum miRNAs reported that were mostly dysregulated in the opposite manner; i.,e., upregulated in nasal swabs, but downregulated in serum. All the studies reported in this figure used RNAseq except the one in the last column reported by Li et al., 2022 that used RT-qPCR.
