Interestingly, analysis of RNA sequencing expression data from tumours and normal samples from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) projects using the web-based tool GEPIA revealed a positive correlation between the expression of P2Y12 and ZEB1 (Pearson correlation coefficient = 0.76, p < 0.05) in PDAC patients (Figure S4B,C). This evidence concerns the gene P2RY12 and neoplasm.
