Role of STIM1- and Orai1-mediated Ca entry in Ca- induced epidermal keratinocyte differentiation
The uppermost thin layer on the surface of the skin, called the epidermis, is responsible for the barrier function of the skin. The epidermis has a multilayered structure in which each layer consists of keratinocytes (KCs) of different differentiation status. The integrity of KC differentiation is crucial for the function of skin and its loss causes or is accompanied by skin diseases. Intracell...
متن کاملThe 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...
متن کاملCLIC4 mediates and is required for Ca2+-induced keratinocyte differentiation.
Keratinocyte differentiation requires integrating signaling among intracellular ionic changes, kinase cascades, sequential gene expression, cell cycle arrest, and programmed cell death. We now show that Cl(-) intracellular channel 4 (CLIC4) expression is increased in both mouse and human keratinocytes undergoing differentiation induced by Ca(2+), serum and the protein kinase C (PKC)-activator, ...
متن کاملSIRT3 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...
متن کاملE2F 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...
