Programmed cell death of epidermal keratinocytes (KC) results in the formation of cornified cells, which constitute the outermost skin layer, the stratum corneum. Here we show by reverse transcription-polymerase chain reaction, western blot, and immunohistochemistry that epidermal KC express caspase-14,... Read More

Epidermal formation depends on a balance between cell proliferation, differentiation, and death. While deletion of IKKα gene blocks terminal differentiation in mice, biochemical pathways regulating IKKα in epidermis are unknown. Notch receptors regulate cell fate in response to ligands such...

EpiDerm™ is an in vitro organotypic human skin model cultured at the air/liquid interface to produce a three-dimensional tissue with a stratum corneum possessing a barrier function similar to native epidermis. The model is suitable for topical application of creams... Read More

Cyclooxygenase-2 (COX-2) appears to play an important role in skin carcinogenesis caused by solar ultraviolet radiation (UVR): UVR induces COX-2 expression in human skin, COX-2 activity is upregulated in skin cancers and COX inhibitors reduce UVR-induced tumor formation. In this... Read More

Establishing an effective epidermal barrier requires a series of coordinated molecular events involving keratinocytes (KCs) within a stratified epithelium. Epidermal maturation depends on convergence of pathways involving components of NF-B and peroxisome proliferator activated receptor (PPAR) signaling systems that promote... Read More
