Abstract

Angiotensin-converting enzyme 2 (ACE2) shares some homology with angiotensin-converting enzyme (ACE) but is not inhibited by ACE inhibitors. The main role of ACE2 is the degradation of Ang II resulting in the formation of angiotensin 1–7 (Ang 1–7) which opposes the actions of Ang II. Increased Ang II levels are thought to upregulate ACE2 activity, and in ACE2 deficient mice Ang II levels are approximately double that of wild-type mice, whilst Ang 1–7 levels are almost undetectable. Thus, ACE2 plays a crucial role in the RAS because it opposes the actions of Ang II. Consequently, it has a beneficial role in many diseases such as hypertension, diabetes, and cardiovascular disease where its expression is decreased. Not surprisingly, current therapeutic strategies for ACE2 involve augmenting its expression using ACE2 adenoviruses, recombinant ACE2 or compounds in these diseases thereby affording some organ protection.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Lower ACE2 may reduce the potential for SARS-CoV-2 invasion, while further ACE2 reduction caused by viral entry may worsen a proinflammatory response that mediates cytokine storm, acute lung injury and ARDS.

    “Decreased expression of ACE2 could mean less potential for SARS-CoV-2 invasion of host cells, and further ACE2 reduction caused by viral entry may exacerbate a heightened proinflammatory response that helps mediate cytokine storm, acute lung injury, and ARDS.”

  • ACE2 is downregulated in people with cardiovascular disease and diabetes, conditions that also correlate with severe COVID-19.

    “ACE2 is also downregulated in humans with cardiovascular disease and diabetes, which also correlate with severe COVID-1965.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
