BACKGROUND: Pandemic COVID-19 by severe acute respiratory syndrome (SARS)
coronavirus 2 (SARS-CoV-2) infection is facilitated by the ACE2 receptor and
protease TMPRSS2. Modestly sized case series have described clinical factors
associated with COVID-19, while ACE2 and TMPRSS2 expression analyses have been
described in some cell types. Patients with cancer may have worse outcomes to
COVID-19. METHODS: We performed an integrated study of ACE2 and TMPRSS2 gene
expression across and within organ systems, by normal versus tumor, across
several existing databases (The Cancer Genome Atlas, Census of Immune Single Cell
Expression Atlas, The Human Cell Landscape, and more). We correlated gene
expression with clinical factors (including but not limited to age, gender, race,
body mass index, and smoking history), HLA genotype, immune gene expression
patterns, cell subsets, and single-cell sequencing as well as commensal
microbiome. RESULTS: Matched normal tissues generally display higher ACE2 and
TMPRSS2 expression compared with cancer, with normal and tumor from digestive
organs expressing the highest levels. No clinical factors were consistently
identified to be significantly associated with gene expression levels though
outlier organ systems were observed for some factors. Similarly, no HLA genotypes
were consistently associated with gene expression levels. Strong correlations
were observed between ACE2 expression levels and multiple immune gene signatures
including interferon-stimulated genes and the T cell-inflamed phenotype as well
as inverse associations with angiogenesis and transforming growth factor-?
signatures. ACE2 positively correlated with macrophage subsets across tumor
types. TMPRSS2 was less associated with immune gene expression but was strongly
associated with epithelial cell abundance. Single-cell sequencing analysis across
nine independent studies demonstrated little to no ACE2 or TMPRSS2 expression in
lymphocytes or macrophages. ACE2 and TMPRSS2 gene expression associated with
commensal microbiota in matched normal tissues particularly from colorectal
cancers, with distinct bacterial populations showing strong associations.
CONCLUSIONS: We performed a large-scale integration of ACE2 and TMPRSS2 gene
expression across clinical, genetic, and microbiome domains. We identify novel
associations with the microbiota and confirm host immunity associations with gene
expression. We suggest caution in interpretation regarding genetic associations
with ACE2 expression suggested from smaller case series.
