Analysis of gene expression in differentiated human primary keratinocytes depleted for MLL2

Project description:Human primary keratinocytes were depleted of MLL2 by siRNA and induced to differentiated for 2 days by addition of Calcium Primary normal human keratinocytes were transfected with MLL2 or scrambled control siRNA using RNAi max (Life Technologies). 24 hours post transfection medium was raised to 1.8mM calcium to induce differentiation. Cells were collected 48 hours later.

RNA-seq of IL-4 stimulated human keratinocytes

Project description:In this study we aim to determine the role of IL-4/STAT6 in gene expression in human keratinocytes using RNA-sequencing approach. Human keratinocytes were cultured for 2 or 5 days with calcium chloride to induce terminal differentiation as determined by the expression of epidermal differentiation complex genes. The cells were then stimulated with IL-4 for 3 and 24 hours, or along the 5 days culture period. We observed that IL-4 inhibits fully differentiation of keratinocytes, induces genes involved with production of inflammatory mediators, and reduces the healing capacity of human keratinocytes. Moreover, STAT6 controlled important genes involved with calcium binding, inflammation and epidermis development. Human keratinocytes were differentiated with calcium chloride for 2 days and incubated with media alone or 20ng/ml of recombinant human IL-4 for 3 and 24 hours. Human keratinocytes were differentiated with calcium chloride for 5 days with or wihout recombinant human IL-4 (20ng/ml). Keratinocytes transfected with control or STAT6 siRNA were differentiated with calcium chloride for 2 days and then stimulated with recombinant huma IL-4 for 24 hours.

Expression profile of proliferating and differentiating primary human keratinocytes in vitro

Project description:Human epidermal keratinocytes undergo tightly controlled program of cell differentiation, leading to the formation of cornified envelope. Primary keratinocytes in vitro, under calcium stimulation mimic the differentiation program observed in vivo. Analysis of the transcription profile of two cell population, such as proliferating cells and differentiating cells helps to discover new genes implicated in that process and to understand the mechanisms of regulation of the keratinocyte differentiation. Primary human keratinocytes were cultured under proliferating (Day 0, sub-confluent cells) and differentiating (seven days of high calcium medium) conditions. As a source of cells, we used normal skin from different body sites: back, foreskin, palmoplantar. RNA extracted from cultured primary human keratinocytes were isolated from five different donors. We compared the expression profiles of proliferating versus differentiating keratinocytes.

Expression data from LINC00958-depleted primary human keratinocytes

Project description:Long non-coding RNAs (lncRNAs) have emerged as important regulators of biological processes and diseases, the function of the majority of epidermal lncRNAs in skin homeostasis and their potential role in psoriasis has remained unknown. We report the identification of lncRNAs with altered expression in psoriasis keratinocytes and identify LINC00958 is overexpressed in psoriasis epidermis. We used microarrays to detail the global programme of gene expression upon LINC00958 depletion in keratinocytes

VZV infection of primary keratinocytes

Project description:Our aim was to investigate the interaction between epidermal differentiation and VZV infection. By means of a calcium-induced keratinocyte differentiation model and RNA-seq we show VZV infection has a profound effect on differentiating keratinocytes and hijacks the normal process of epidermal gene expression to generate a signature resembling patterns of gene expression seen in both heritable and acquired skin-blistering disorders. Analysis of the viral transcriptome provides evidence that VZV replication in skin is tightly linked to differentiation and critically, that late viral gene expression is associated with cellular differentiation. The experiment was performed on human primary keratinocytes under four conditions: undifferentiated/uninfected, uninfected/differentiated, VZV-infected/undifferentiated and VZV-infected/differentiated.
