Two cBioportal breast cancer datasets, the Invasive Breast Carcinoma (TCGA, PanCancer Atlas) and Firehose Legacy, which also includes invasive breast carcinoma samples, both showed significant correlation between low P2Y2 expression and a smaller percentage chance of disease-free survival (Figure 6A,B) [34,35]. This evidence concerns the gene P2RY2 and invasive breast carcinoma.
