Epidermal Gene Expression Regulator

The term "epidermal gene expression regulator" refers to a set of molecules—primarily transcription factors and signaling pathways—that control the specific patterns of gene expression required for epidermal (skin) development, differentiation, and homeostasis. These regulators ensure that keratinocytes (the main cell type in the epidermis) proliferate, differentiate, and function properly. Key regulators include transcription factors like p63, AP-1, Ets, AP-2 families, and signaling pathways like the EGFR pathway. These components work together to control biological processes like ectoderm development, epidermal cell differentiation, and formation of the cornified envelope. Disruption of these regulators can lead to developmental defects or disease states such as cancer or skin barrier disorders.
