The pandemic of Corona Virus Disease 2019 (COVID-19), a respiratory disease caused by a novel severe acute respiratory syndrome coronavirus (SARS-CoV-2), is causing substantial morbidity and mortality. Along with the respiratory symptoms, underlying diseases in senior patients such as diabetes, hypertension and coronary heart disease are the most common comorbidities, which cause more sever outcomes, even death. During the attach and entry of SARS-CoV-2, the key protein involved is the Angiotensin I Converting Enzyme 2 (ACE2) located on the membrane of host cells. Here, we aim to curate an expression profile of Ace2 and other COVID-19 related genes across the available diabetes murine strains. Based on strictly manual curation and bioinformatics analysis of the publicly deposited expression datasets, Ace2 and other potential proteins such as Furin, Tmprss2, Ang, Ang2 were examined. We found that Ace2 expression is rather ubiquitous in three diabetes prone strains (db/db, ob/ob and DIO). With the most abundant datasets presence, liver shows a medium Ace2 level compared with lung, pancreatic islet, brain and even T cell. Age is a critical factor for Ace2 expression in db/db than the other two strains. Other four host genes except Ace2 showed correlation to each other at varied levels. To accelerate the researches of the interaction between COVID-19 and the underlying diseases, transcriptomics database of Murine4Covid (www.geneureka.org/Murine4Covid) will facilitate the design of research on COVID-19 and underlying diseases.

Summary of Ace2 expression in mouse tissues based on publicly available transcriptomics datasets. Different sizes of circles represent normalized expression levels of Ace2, and scaled colors of circles represent number of samples curated in certain tissue of strain. A consistent expression in the lung, pancreatic islet, liver, adipose, heart, aortas, brain, kidney, gall bladder, muscle and T cells was observed across all datasets. Blank in situ represents no qualified dataset available. Intensity is normalized and shown as to /(103 intensity of geometric mean of Gapdh and Actb).
