For example, CTNND1 had significant differences in comparing the expression pattern of a pair of isoforms, both with high detection rate, in luminal and basal-like samples, even though no statistical difference was seen in the total gene expression level comparison (Fig. 3a); this same switching pattern was also seen in the PanCan12 3308 tumor data set when we focused on the Squamous Genomic Group versus LUAD-enriched Group (Fig. 3b), thus suggesting that this pattern is conserved across related cell and/or tumor subtypes. This evidence concerns the gene CTNND1 and neoplasm.
