The angiotensin-converting enzyme 2 (ACE2) is the receptor for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is highly expressed in adipose tissue, possibly associated with progression to severe coronavirus disease 2019 (COVID-19) in obese subjects. We searched the Gene Expression Omnibus (GEO) and reanalyzed the GSE59034 containing microarray data from subcutaneous white adipose tissue (sWAT) biopsies from 16 women before and 2 years after RYGB, and 16 controls matched by sex, age, and BMI. After RYGB, there was a significant decrease in sWAT ACE2 gene expression (logFC=-0.4175, P=0.0015). Interestingly, after RYGB the sWAT ACE2 gene expression was significantly lower than in non-obese matched controls (LogFC=-0.32875, P=0.0014). Our data adds to the well-known benefits of RYGB, a potential protective mechanism against COVID-19.
