The present invention provides a novel DNA microarray chip that can be used for simultaneous testing of transcriptional responses to cutaneous stressors in the context of neuro-endocrine-immune functions of the skin. The transcriptional responses to ultraviolet radiation in epidermal keratinocytes were tested using such microarray chip containing more than 700 neuro-endocrine-immune related genes. The gene expression pattern was non-random and time dependent; it included increased expression of genes involved in water and salt balance, prostaglandin synthesis, keratinocyte differentiation as well as genes coding for stress effectors, cytokines and metalloproteinases. In contrast, expression was decreased for genes coding for growth factors and their receptors, and for elements of extracellular matrix. This stochastic pattern suggests that transcriptional responses are coordinated and aimed at preservation of epidermal barrier function, prevention of early carcinogenic events and remodeling of extracellular matrix.
