NRP1, the ACE2-dependent co-receptor, and TMEM106B, a proviral host factor for SARS-CoV-2 were differentially expressed in all the four tumors (4, 5) . Among the three potential SARS-COV-2 receptors identified by Zhu et al, LDLRAD3 was significantly up-regulated in lung cancer, esophageal carcinoma and B-cell lymphoma, CLEC4G was significantly up-regulated in leukemia, and TMEM30A was significantly up-regulated in esophageal carcinoma, B-cell lymphoma and leukemia (4) . Interestingly, whether in normal tissues or tumor tissues, the level of ACE2 expression was quite low. We believed that the SARS-COV-2 receptor that made cancer patients more susceptible to infection was unlikely to be ACE2. In summary, we explained the potential reasons why patients with four malignant tumors were more susceptible to COVID-19, namely the upregulation of SARS-COV-2 receptors in tumor tissues made individuals more likely to be infected by SARS-COV-2. We suggested NRP1, TMEM106B, LDLRAD3, TMEM30A and CLEC4G as a potential genetic shared genes for tumors and COVID-19, but ACE2 might not be included.
