ACE2 and lung carcinoma: In order to better understand the transcriptional response of lung cells to the SARS-CoV-2 infection, Albrecht and tenOever laboratories profiled the RNA-seq gene expression from human NHBE (Normal Human Bronchial Epithelial) cells, A549 lung cancer cells (no ACE2 expression), A549_ACE2 (A549 lung cancer cells transduced with a vector expressing human ACE2), and CALU-3 lung cancer cells (with ACE2 expression), and 2 human lung samples infected by SARS-CoV-2 [14].
