BACKGROUND Chronic skin inflammation in atopic dermatitis (AD) is associated with elevated expression of proinflammatory genes and activation of innate immune responses in keratinocytes. microRNAs (miRNAs) are short, single-stranded RNA molecules that silence genes via the degradation of target mRNAs or inhibition of translation. OBJECTIVE The aim of this(More)
BACKGROUND Enhanced apoptosis of keratinocytes is the main cause of eczema and spongiosis in patients with the common inflammatory skin disease atopic dermatitis (AD). OBJECTIVE The aim of the study was to investigate molecular mechanisms of AD-related apoptosis of keratinocytes. METHODS Primary keratinocytes isolated from patients with AD and healthy(More)
MicroRNAs are short non-coding RNAs that regulate gene expression. Previously, in a genome-wide screen, we found deregulation of microRNA expression in psoriasis skin. MicroRNA-21 (miR-21) is one of the microRNAs significantly up-regulated in psoriasis skin lesions. To identify the cell type responsible for the increased miR-21 level, we compared expression(More)
Brooke-Spiegler syndrome (BSS; OMIM 605041) is an autosomal dominant condition characterized by skin appendageal neoplasms including cylindromas, trichoepitheliomas, and/or spiradenomas. In 1996, the gene locus for BSS was mapped to 16q12-13, and, in 2000, mutations in the cylindromatosis (CYLD) gene were determined to cause BSS, familial cylindromatosis(More)
Lipedema is a disproportional obesity featuring frequent hematoma formation due to even minor traumatic injuries. On the basis of clinical observations, complete decongestive physiotherapy diminishes the incidence of hematomas due to minor injuries beyond leg volume reduction. Hematoma development may be caused by altered capillary resistance (CR) or(More)
Epidermolysis bullosa pruriginosa (EBP; OMIM #604129) is an unusual variant of autosomal dominant (or occasionally recessive) dystrophic epidermolysis bullosa (DEB) in which intense itching and scratching impacts upon the phenotype (1, 2). Although trauma-induced blistering often occurs, and toenail dystrophy is almost universal, the skin lesions can often(More)
Psoriasis Susceptibility-Related RNA Gene Induced by Stress (PRINS) is a non-coding RNA overexpressed in lesional and non-lesional psoriatic epidermis and induced by stress. Its function in healthy and psoriatic skin is still not known. Here, we report that PRINS regulates G1P3, a gene with anti-apoptotic effects in keratinocytes. siRNA-mediated inhibition(More)
MicroRNAs (miRNAs) are short, single-stranded, noncoding RNAs that play important roles in the regulation of gene expression. We previously identified a characteristic miRNA expression profile in psoriasis, distinct from that of healthy skin. One of the most downregulated miRNAs in psoriasis skin was microRNA-125b (miR-125b). In this study, we aimed to(More)
