We found that furin might elevate ACE2 expression in both LUAD (Figure 9B, C) and UCEC (Figure 9B, D); might reduce ACE2 expression in COAD (Figure 8B); might elevate HSPA5 expression in PAAD (Figure 9B, E); and might elevate TMPRSS2 expression in BRCA (Figure 8B, F). Here, ACE2 is linked to pancreatic adenocarcinoma.
