Fig. 5. The signaling pathway by which p63 affects CSCs in epithelial cancers.
A Distinct expression levels of the p63 protein in different tumor tissues (The Human Protein Atlas, https://www.proteinatlas.org/ENSG00000073282-TP63/pathology). B The ΔNp63 isoform plays a crucial role in regulating various signaling pathways implicated in CSC stemness regulation, particularly in breast and SCC cancers. C p63 regulates ALDH1A1 in the context of prostate cancer, in which p63 affects CSC stemness. D TAp63 modulates the expression of specific Hippo pathway components to regulate the stemness of CSCs in breast cancer.
