E-MTAB-1640 - Transcription profiling by array of two HPV16 E6/E7 immortalized skin keratinocyte cell lines, NEB1 and KEB7, derived from a healthy individual and a patient suffering from Dowling-Meara type epidermolysis bullosa simplex (EBS-DM), respectively

Dowling-Meara type epidermolysis bullosa simplex (EBS-DM) is a severe blistering disease, caused by dominant mutations in either the keratin-5 (K5) or keratin-14 (K14) gene. K5 and K14 are the major components of the intermediate filament (IF) network in basal keratinocytes. Due to the dominant nature of EBS-DM, misfolded K5 or K14 proteins are incorporated into intermediate filaments, rendering them sensitive to mechanical stress. Upon trauma, these filaments disrupt and the keratinocytes lyse, leading to intra-epidermal blistering. The dominant nature of K5 and K14 mutations in EBS-DM represents a challenge to gene therapeutic approaches. Therefore, we investigated the gene expression profile of a K14 mutant keratinocyte cell line (KEB7) and compared it to the gene expression profile of a wild-type keratinocyte cell line (NEB1). The aim of this study was to identify differentially regulated genes as potential therapeutic targets for the development of new therapies.
