TP53 and basal cell carcinoma: IPA analysis for all differentially expressed genes in SCC vs. normal tissue revealed basal cell carcinoma signalling (FDR = 3.72 × 10−6, ratio = 33/70), p38 MAPK signalling pathway (FDR = 1.29 × 10−5, ratio = 32/54), p53 signalling pathway (FDR = 7.59 × 10−3, ratio = 34/62), and noradrenaline degradation (FDR = 7.05 × 10−4, ratio=16/30) as the top canonical pathways, not disclosed in ADC (Figure 4B).
