ACE2 and lung adenocarcinoma: These datasets were obtained from four cell lines: normal human bronchial epithelial cell line (NHBE), human lung adenocarcinoma alveolar epithelial cell line (A549) with and without overexpressed angiotensin-converting enzyme 2 (ACE2; host receptor to which SARS-CoV-2 binds and enters the cell), and human lung adenocarcinoma airway epithelial cell line (Calu-3).
