January 2016 in “Development” The study demonstrated that the transcription regulators YAP and TAZ were essential for maintaining skin homeostasis by promoting the proliferation of basal layer stem/progenitor cells. In both mouse and human skin, YAP and TAZ localized in the nucleus of basal layer cells, regulated by integrin-Src signaling. Deletion of YAP and TAZ in mice resulted in slowed cell proliferation, hair loss, and impaired wound healing, underscoring their role in skin regeneration. The research highlighted the importance of integrin-Src and EGFR-PI3K signaling pathways for YAP nuclear localization, which was crucial for cell cycle progression and growth. Additionally, YAP acted as a sensor of epithelial cell polarity, with its localization influenced by apical-basal polarity signals. These findings provided insights into the molecular mechanisms of skin renewal and the potential impact of YAP and TAZ on skin-related conditions and cancer.

February 2006 in “Cancer Research” The study investigated the role of Patched1 (Ptch1) in cell cycle progression and its function as a gatekeeper in preventing tumorigenesis, particularly in skin tumors resembling human basal cell carcinoma (BCC). Researchers found that loss of Ptch1 in mouse models led to rapid skin tumor formation, increased nuclear accumulation of cyclin D1 and B1, and enhanced cell proliferation, indicating Ptch1's role as a tumor suppressor. The study highlighted that Ptch1 loss predisposed cells to a tumorigenic fate by facilitating cell cycle progression, rather than through Wnt signaling. The research suggested that targeting the Hedgehog pathway, which involves Ptch1, could be a potential therapeutic strategy for cancer treatment, as inhibiting this pathway induced tumor regression in Ptch1-deficient mice.
