Chen and colleagues examined how AXL, Angiotensin-converting enzyme 2 (ACE2), dipeptidyl peptidase-4 (DPP4), Alanyl Aminopeptidase (ANPEP), Transmembrane serine protease 2 (TMPRSS2), and Glutamyl Aminopeptidase (ENPEP) could be carcinogenic as secondary pathways that the SARS-CoV-2 virus uses to its benefit as glioblastoma progresses. Here, ACE2 is linked to glioblastoma.
