ACE2 and lung adenocarcinoma: Remarkably, ACE2 was significantly up‐regulated in cervical squamous cell carcinoma and endocervical adenocarcinoma, colon adenocarcinoma, kidney renal papillary cell carcinoma, oesophageal carcinoma, lung adenocarcinoma and uterine corpus endometrial carcinoma compared to controls (Figure 1E, P < 0.05), suggesting that the patients with these tumours may face higher injury risk than the individuals without cancer after SARS‐CoV‐2 infection.
