Fig. 1. Tissue expression and localization of AR, TMPRSS2, and ACE2 in mice versus in humans.

Fig. 1

a The relative mRNA expression levels of Ar, Tmprss2, and Ace2 in prostate (n = 3), lungs (n = 3), small intestine (n = 3), and kidneys (n = 3) in 8-week-old male C57BL/6 mice were quantified by qRT-PCR. qPCR values (mean ± SD) are expressed as mRNA copies/µg total RNA. b The mRNA expression levels of AR, TMPRSS2, and ACE2 in the prostate (n = 152), lungs (n = 427), small intestine (n = 137), and kidneys (n = 45) in adult humans were extracted from the “The Human Protein Atlas/The Genotype-Tissue Expression (GTEx) Dataset”. GTEx dataset reports mRNA expression of each gene in human tissue as average pTPM. The data were presented by box plots showing all values. c The localization of AR, TMPRSS2, and ACE2 in the prostate, lungs, small intestine, and kidneys in 8-week-old male C57BL/6 mice were displayed by immunohistochemistry (IHC). d The IHC images of AR, TMPRSS2, and ACE2 in the prostate, lungs, small intestine, and kidneys in adult humans were extracted from the “The Human Protein Atlas/Protein Expression Summary” subcategory. In the database of The Human Protein Atlas, IHC staining was performed on normal human tissue. The scale bar of representative images is ×40 by 100 μm.
