Mutant p63 affects epidermal cell identity through rewiring the enhancer landscape

Project description:<p>Transcription factor p63 is a key regulator of epidermal keratinocyte proliferation and differentiation. Mutations in the p63 DNA-binding domain are associated with Ectrodactyly Ectodermal Dysplasia Cleft Lip/Palate (EEC) syndrome. Underlying molecular mechanism of these mutations however remain unclear. Here we characterized the transcriptome and epigenome of p63 mutant keratinocytes derived from EEC patients. The transcriptome of p63 mutant keratinocytes deviated from the normal epidermal cell identity. Epigenomic analyses showed an altered enhancer landscape in p63 mutant keratinocytes contributed by loss of p63-bound active enhancers and by unexpected gain of enhancers. The gained enhancers were frequently bound by deregulated transcription factors such as RUNX1. Reversing RUNX1 overexpression partially rescued deregulated gene expression and the altered enhancer landscape. Our findings identify an unreported disease mechanism whereby mutant p63 rewires the enhancer landscape and affects epidermal cell identity, consolidating the pivotal role of p63 in controlling the enhancer landscape of epidermal keratinocytes.</p>

Circular RNA circASH1L protects miRNA-129-5p from target-directed microRNA degradation in human skin wound healing [circASH1L knockdown]

Project description:In an RNAseq analysis, we have identified the circular RNA cASH1L with high levels in acute wounds (day1 to day7) compared to normal skin. The biological function of cASH1L in human epidermal keratinocytes during wound repair has not been studied. To study the genes regulated by cASH1L, we transfected siRNA targeting the diagnostic junctions of cASH1L into human primary epidermal keratinocytes to knockdown cASH1L expression. We performed a global transcriptome analysis of keratinocytes upon circRNA knockdown using Affymetrix arrays.

A global transcriptome analysis of human epidermal keratinocytes upon knockdown of hsa_circ_0084443

Project description:Hsa_circ_0084443 expression level is down-regulated during normal skin wound healing and higher level of hsa_circ_0084443 was found in chronic non-healing diabetic foot ulcers compared to normal wounds. However, the biological function of hsa_circ_0084443 in epidermal keratinocytes during wound repair has not been studied. To study the genes regulated by hsa_circ_0084443, we transfected siRNA targeting hsa_circ_0084443 diagnostic junction into human primary epidermal keratinocytes to knockdown hsa_circ_0084443 expression. We performed a global transcriptome analysis of keratinocytes upon knockdown of hsa_circ_0084443 using Affymetrix arrays.

Gene expression profile of primary epidermal keratinocytes (HEKs) stimulated with lawsone

Project description:The study aimed to interrogate whether the 1,4-naphtoquinone derivative lawsone activates the aryl hydrocarbon receptor (AhR) downstream transcriptional program in keratinocytes and is capable of modulating skin homeostasis. The study has been performed on human primary epidermal keratinocytes (HEKs), which represent the first line of defense against exogenous molecules. HEK cells were treated with the vehicle control DMSO (control), stimulated with lawsone or with the TLR2 ligand Pam2CSK4. Transcriptional profiles of HEK cells were studied to investigate the regulation of AhR -related genes, Nrf2-related genes and epidermal differentiation and keratin genes. We demonstrated that lawsone was sensed by keratinocytes and activated AhR. In particular, lawsone efficiently activated the transcriptional program of AhR and promoted keratinocyte differentiation.

Circular RNA circASH1L protects miRNA-129-5p from target-directed microRNA degradation in human skin wound healing [miR129 overexpression]

Project description:In an RNAseq analysis, we have identified the microRNA hsa-miR-129-5p with high levels in acute wounds (day1 to day7) compared to normal skin. The biological function of this miRNA in human epidermal keratinocytes during wound repair has not been studied. To study the genes regulated by miR-129-5p , we transfected miR-mimics targeting miR-129-5p into human primary epidermal keratinocytes to over-express miR-129-5p expression. We performed a global transcriptome analysis of keratinocytes upon miRNA overexpression using Affymetrix arrays.
