Among the most significant candidates in the kidney cell analysis (summarized in Fig 22C), we again focused on non‐cancer datasets and observed that the chemotherapy drug cisplatin upregulated ACE2 in mice kidney samples, while it downregulated ACE2 in the renal cortex of rat (logFC = 0.29 and −1.16, adjusted P = 8.06E−3 and 2.36E−5, respectively, Fig 22D), suggesting a cell type and possibly species‐specific effect. Here, ACE2 is linked to cancer.
