Project description:We used microarray analysis to investigate if keratinocytes excert an immuno-inflammatory response towards streptococcal M1 protein. Keratinocytes respond to M1 protein by activating pathways to induce the production of inflammatory signaltransducers, AP-1 and NFkB transcription factor subunits, together with inflammatory mediators such as IL-8, CCL20 and IL-1 family proteins etc.

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.

Project description:IL-17C is important for the pathogenesis of inflammatory diseases such as IBD and psoriasis. We found that IL-17C is highly induced in a murine model of psoriasis. Recent results suggest that IL-17C can target epithelial cells that express both IL-17RA and IL-17RE receptor chains. Here we identify genes induced in response to IL-17C treatment of human keratinocytes to provide the tools for dissection of the IL-17C signaling pathway. Human keratinocytes, HEKn, were incubated in the absence (n = 3) and presence (n = 5) of 500 ng/ml recombinant human IL-17C for 3 and 24 hours. Whole RNA was isolated via RNeasy kit (Qiagen).

Project description:We used microarrays to investigate if keratinocytes excert an immuno-inflammatory response towards M1 protein. Keratinocytes respond to M1 protein by activating pathways to induce the production of inflammatory signaltransducers, AP-1 and NFkB transcription factor subunits together with inflammatory mediators such as IL-8, CCL20 and IL-1 family proteins etc. HaCaT cells were cultured in serum-free media, without calcium, until 80% confluency. Cells were incubated in absence or presence of M1 protein before RNA extraction. The integrity of RNA quality was analysed by an Bioanalyzer. Out of 12 samples, 3 M1 stimulated and 3 control samples were chosen for hybridization on Affymetrix Human 2.0 ST array.

Project description:miR-10a has been shown to regulate proliferation and invasiveness of cancer cells and inflammatory responses of endothelial cells. The function of miR-10a in the skin has not been studied before. Here we examined miR-10a expression, regulation and functions in keratinocytes (KCs) in association with atopic dermatitis (AD).

Project description:Mutations of TCF4, which encodes a basic helix-loop-helix transcription factor, cause Pitt-Hopkins syndrome (PTHS) via multiple genetic mechanisms. TCF4 is a complex locus expressing multiple transcripts by alternative splicing and use of multiple promoters. We report a three-generation family segregating mild intellectual disability with an apparently balanced chromosomal translocation t(14;18)(q23.3;q21.2) that we characterized as a complex unbalanced karyotype 46,XY,der(14)del(14)(q23.3q23.3)t(14;18)(q23.3;q21.2)del(18)(q21.2q21.2) del(18)(q21.2q21.2)inv(18)(q21.2q21.2),der(18)t(14 ;18)(q23.3;q21.2) disrupting TCF4. Using whole genome sequencing, transcriptome sequencing, qRT-PCR and nCounter analysis, we characterized the breakpoint junctions from derivative chromosomes and gene expression at the TCF4 locus. Our analyses revealed that family members segregating mild intellectual disability with the complex chromosome aberration had normal expression of genes along chromosomes 14 or 18 and no marked changes in expression of genes other than TCF4. Affected individuals had 12-33 fold higher mRNA levels of TCF4 than did unaffected controls or individuals with PTHS. Increased levels of TCF4 transcript variants originating distal to the translocation breakpoint, not the fusion transcript generated by the derivative chromosome, contributed to this increased. Although validation in additional patients is required, our findings suggest that the dysmorphic features and severe intellectual disability characteristic of PTHS is partially rescued by overexpression of short TCF4 transcripts encoding a nuclear localization signal, a transcription activation domain, and the basic helix-loop-helix domain.

Project description:Haplo-insufficiency of TCF4 induced by mutations or microdeletion of TCF4 gene causes Pitt-Hopkins Diseases. Recent gene association studies revealed that mutations of TCF4 is significantly associated with schizophrenia. But the role of TCF4 in developing neocortex is not known. The goal of this study is to identify TCF4 itranscriptional regulatory pathways in developing neocortex by analyzing transcriptomes of dorsal telencephalons of TCF4knockout, TCF4Heterozygote and WT littermates and comparing differential expressed genes between these genotypes.
