TGFB1 and cancer: In view of the important effects of TGFβ and ΔNp63 in SCC development and progression, and the discrepant results reported for their regulatory connections in normal or cancer cells of different tissue origins, we performed an in-depth analysis of non-malignant and malignant squamous cells using consistent growth conditions and exposures to clarify the effects of TGFβ on p63 in this cell type.
