E2F Modulates Keratinocyte Squamous Differentiation

E2F regulation is essential for normal cell cycle progression. Therefore, it is not surprising that squamous cell carcinoma cell lines (SCC) overexpress E2F1 and exhibit deregulated E2F activity when compared with normal keratinocytes. Indeed, deliberate E2F1 deregulation has been shown to induce hyperplasia and skin tumor formation. In this study, we report on a dual role for E2F as a mediator...

Pirh2 E3 Ubiquitin Ligase Modulates Keratinocyte Differentiation Through p63

p63, a homolog of the tumor-suppressor p53, is essential for the development of the epidermis and limbs. p63 is highly expressed in the epithelial cell layer and acts as a molecular switch that initiates epithelial stratification. However, the mechanisms controlling p63 protein levels are still far from being fully understood. Here, we demonstrate a regulatory protein for p63 activity. We found...

Ca2+ and BMP-6 signaling regulate E2F during epidermal keratinocyte differentiation.

The epidermis consists of a squamous epithelium continuously replenished by committed stem cells, which can either self-renew or differentiate. We demonstrated previously that E2F genes are differentially expressed in developing epidermis (Dagnino, L., Fry, C. J., Bartley, S. M., Farnham, P., Gallie, B. L., and Phillips, R. A. (1997) Cell Growth Differ. 8, 553-563). Thus, we hypothesized that v...

The keratinocyte growth-differentiation switch.

Growth/differentiation control of normal epithelial cells has been relatively understudied, because of the complexities involved in their cultivation and characterization. The present review is focused on progress in this area using the mouse primary keratinocyte system. This system reproduces under well defined culture conditions the switch between epithelial cell growth and differentiation wh...

SIRT3 regulation of keratinocyte differentiation

Background: SIRT3 plays a major role in protecting against mitochondrial oxidative stress. Results: Oxidative stress increases during keratinocyte differentiation, and SIRT3 can decrease differentiation by attenuating oxidative stress. Conclusion: SIRT3-induced down regulation of mitochondrial oxidative stress attenuates keratinocyte differentiation. Significance: Understanding the regulation o...
