Coronaviruses such as MERS-CoV and SARS-CoV-2 infect the human respiratory tract
and can cause severe pneumonia. Disease severity and outcomes are different for
these two infections: the human mortality rate for MERS-CoV and SARS-CoV-2 is
over 30% and less than 10%, respectively. Here, using microarray assay, we
analyzed the global alterations in gene expression induced by MERS-CoV or
SARS-CoV-2 infections in primary human pulmonary epithelial cells. Overall, the
number of differentially expressed genes was higher in human lung cells infected
with MERS-CoV than in cells with SARS-CoV-2. Out of 44,556 genes analyzed, 127
and 50 were differentially expressed in cells infected with MERS-CoV and
SARS-CoV-2, respectively (> 2-fold increase, compared to uninfected cells). Of
these, only eight genes, including the one coding for CXCL8, were similarly
modulated (upregulated or downregulated) by the two coronaviruses. Importantly,
these results were virus-specific and not conditioned by differences in viral
load, and viral growth curves were similar in human lung cells infected with both
viruses. Our results suggest that these distinct gene expression profiles,
detected early after infection by these two coronaviruses, may help us understand
the differences in clinical outcomes of MERS-CoV and SARS-CoV-2 infections.
