Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses the angiotensin-converting enzyme 2 (ACE2) receptor for cell entry. This study found higher ACE2 gene expression in human breast tissue than lung tissue, suggesting potential SARS-CoV-2 infection of the breast.
Area of Science:
- Virology
- Genomics
- Pathology
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) entry into host cells depends on binding to the angiotensin-converting enzyme 2 (ACE2) receptor.
- ACE2 receptors are present in various human tissues, including the lungs, a primary target for SARS-CoV-2.
- Previous research has not confirmed SARS-CoV-2 infection in human breast tissue.
Purpose of the Study:
- To investigate the expression of the ACE2 gene in human breast tissue.
- To compare ACE2 gene expression levels in breast tissue with those in lung tissue.
Main Methods:
- Utilized a public gene expression database.
- Performed a search to identify and analyze ACE2 gene expression data in human breast tissue samples.
Main Results:
- ACE2 gene expression was detected in human breast tissue.
- The expression level of the ACE2 gene was found to be higher in human breast tissue compared to human lung tissue.
Conclusions:
- The elevated ACE2 expression in breast tissue suggests it could be a potential target for SARS-CoV-2.
- This finding implies that SARS-CoV-2 infection may lead to pathology in breast tissue.
- Further research is warranted to understand the implications of ACE2 expression in breast tissue concerning COVID-19.
