The TNMPlot (https://tnmplot.com/) online tool was used to compare laminin transcript abundance in RNAseq data between normal pancreas from the GTEx dataset and PAAD tumour tissues from TCGA dataset (n; normal = 252, tumour = 177, Figures 2A, B; Supplemental Material S1A, S1B). This evidence concerns the gene LAMB2 and pancreatic adenocarcinoma.
