For instance, we showed a minority of TCGA glioblastoma samples had an expression of AGTR2 (19/160), which aligned with a previous study that showed a lack of AGTR2 mRNA (nanostring expression) and protein expression (immunoblot) in a small cohort of glioblastoma cases; however, this protein was expressed on the microvessels and stem cells of glioblastoma through immunohistochemistry [20]. Here, AGTR2 is linked to glioblastoma.
