(Submitter supplied) Disrupted skin barrier due to altered keratinocyte differentiation is common in pathologic conditions such as atopic dermatitis, ichthyosis and psoriasis. However, the molecular cascades governing keratinocyte terminal differentiation are still poorly understood. We have previously demonstrated that a dominant mutation in ZNF750 leads to a clinical phenotype that reminiscent of psoriasis and seborrheic dermatitis. more...

(Submitter supplied) Disrupted differentiation is a hallmark of numerous diseases, which in epidermis alone impact >25% of the population. In a search for dominant mediators of differentiation, we defined a requirement for the ZNF750 nuclear protein in terminal epidermal differentiation. ZNF750 controlled genes mutated in numerous human skin diseases, including FLG, LOR, LCE3B, ALOXE3, and SPINK5. ZNF750 potently induced progenitor differentiation via an evolutionarily conserved C2H2 zinc finger motif. more...

(Submitter supplied) The skin epidermis is a constantly renewing stratified epithelial tissue that provides essential protective barrier functions. The major barrier is at the outermost layers of the epidermis, formed by terminally differentiated keratinocytes reinforced by proteins and lipids of their cornified envelope (CE), and disruptions to this process characterizes common skin disorders. ZNF750 is an epithelial transcription factor essential for in vitro keratinocyte differentiation, whose autosomal dominant mutation in humans causes psoriasis-like skin disease. more...

(Submitter supplied) Glucocorticoids (GCs) have a long history of use as therapeutic agents for numerous skin diseases. Surprisingly, their specific molecular effects are largely unknown. To characterize GC action in epidermis, we compared the transcriptional profiles of primary human keratinocytes untreated and treated with dexamethasone (DEX) for 1, 4, 24, 48 and 72 hours using large-scale microarray analyses. The majority of genes were found regulated only after 24 hours and remained regulated throughout the treatment. more...

(Submitter supplied) Interleukin-1 is a proinflammatory and immunomodulatory cytokine that plays a crucial role in inflammatory diseases of the skin, including bacterial infections, bullous diseases, UV damage and especially psoriasis. To characterize the molecular effects of IL-1 in epidermis, we defined the transcriptional changes in human epidermal keratinocytes 1, 4, 24, and 48 h after treatment with IL-1a. IL-1 significantly regulated 388 genes, including genes associated with proteolysis, adhesion, signal transduction, proliferation, and epidermal differentiation. more...

Each treatment condition have 2 or 3 replicates. 10 million reads were collected. A total of 8202 genes were designated as present (RPKM>5 in at least one sample). 635 genes were differentially expressed (FDR<0.01, P<0.000774201). more...

We compared gene expression profiles between AhR Wt and AhR KO primary mouse keratinocyte cultures. We identified 391 genes that were differentially expressed with a 1.5 fold cutoff and p<.05, and identified the AhR as an important regulator of genes involved in normal epidermal differentiation.

(Submitter supplied) In an RNAseq analysis, we have identified the HOXC13-AS significantly downregulated in wound biopsies and epidermal cells compared to skin counterparts. To study the genes regulated by HOXC13-AS, we transfected HOXC13-AS siRNA pool into human primary epidermal keratinocytes to knockdown HOXC13-AS and induced cell differentiation for 3 days by 1.5 mM calcium. We performed a global transcriptome analysis of keratinocytes upon the HOXC13-AS knockdown using Affymetrix arrays.

(Submitter supplied) Due to microRNAs' (miRs) important functions and high potential for disease diagnosis and therapy, increasing efforts have been put to understand their role in wound repair and identify targetable miRs for wound treatment. However, lack of knowledge about miR-mediated gene expression in human wound tissues hinders the recognition of clinically relevant miRs. Here we profiled genome-wide miR and mRNA expression by RNA-sequencing in the same set of samples from human normal acute wounds and chronic non-healing venous ulcers (VU). more...
