Figure 2. Comparison of A2AR (A) and A2BR (B) expression among Pam50 breast cancer subtypes in the METABRIC. A2BR is significantly higher expressed in basal like breast cancer compared to other breast cancer subtypes (***P = 3.9e-11). Gene expression data from The Cancer Genome Atlas (TCGA) and Molecular Taxonomy of Breast Cancer International Consortium (METABRIC) were downloaded from the Gene expression Omnibus database [GEO: GSE62944] and Synapse software platform (syn1688369; Sage Bionetworks, Seattle, WA, USA), respectively
