Dkk4 and Eda regulate distinctive developmental mechanisms for subtypes of mouse hair-1

Project description:Dkk4 transgenic mice in wild-type background showed abnormal hair subtype formation. Gene expression profiling showed significant down regulation of hair follicle-related keratin genes and hair keratin-associated protein genes at E18.5 and P1. Keywords: development or differentiation design,genetic modification design To define target genes of Dkk4 during hair follicle development, we carried out microarray experiments with mouse back skin samples that from 4 developmental time points including E14.5, E16.5, E18.5 and P1 of wild-type and wild-type background Dkk4 transgenic mice.

Fgf18 regulates hair cycle

Project description:Fgf18 gene is strongly expressed in hair follicles of mouse dorsal skin during regressing (catagen) and resting (telogen) phases of hair cycle, but not in growth (anagen) phase. This study aims at identifying the function of Fgf18 in the regulation of hair cycle. To define target genes of Fgf18 during telogen phase of hair cycle, we generated mice in which Fgf18 gene is conditionally knocked out in keratin 5-positive epithelial cells (referred to as Fgf18 cKO below). We carried out microarray experiments with mouse back skin samples harboring telogen hair follicles obtained from three 42-d-old Fgf18 cKO male mice, or from three 42-d-old C57BL/6 male mice as control. Total RNA was isolated from each mouse and further purified to polyA RNA using oligo dT30 columns. The RNA samples were pooled for each group. Gene expression was analyzed by one-color analysis using duplicate arrays for each group.

Keratins control Nrf2 by regulating mitochondrial activity and barrier composition / Keratin-dependent TSLP expression suggests a link between skin blistering and atopic disease

Project description:The epidermal barrier protects the body against mechanical injury, infection and dehydration. The respective contribution of type I and type II keratins which form the major cytoskeleton in epidermal keratinocytes in barrier formation and stress protection is incompletely understood. Here, we reveal a novel mechanism by which keratins control anti-oxidant responses through barrier-dependent and cell-autonomous mechanisms. Mice lacking the entire type I (KtyI) or type II (KtyII) keratin gene clusters suffer from distinct prenatal barrier defects. Comparative transcriptome profiling identifies essential cornified envelope components and reveals strong upregulation of the bZIP transcription factor Nrf2 in situ. Isolated keratinocytes from both strains of mice show elevated mitochondrial oxygen consumption and Nrf2 activity, decreased upon keratin re-expression. We propose a model in which keratins control mitochondria-derived oxidative stress via Nrf2 activation. Our findings reveal major contributions of keratins to chronic inflammation and autoimmune disorders. Total RNA obtained from E18.5 embryo back skin from typeI and II keratin knockout compared with respective wild type.

DNA Microarray and Bioinformatic Analysis Reveals the Potential of Whale Oil in Enhancing Hair Growth in C57BL/6 Mice

Project description:Much research has been conducted to determine how hair regeneration is regulated, as this could provide therapeutic, cosmetic, and even psychological interventions for hair loss. The current study focused on the hair growth effect and effective utilization of fatty oil obtained from Bryde's whales through high-throughput DNA microarray approach in conjunction with immunohistochemical observations. The research also examined the mechanisms and factors involved in hair growth. In an experiment using female C57BL/6J mice, the vehicle control group (VC: propylene glycol: ethanol: water), the positive control group (MXD: 3% minoxidil), and the experimental group (WO: 20% Whale Oil) were topically applied to the back of the mouse. The results showed that 3% MXD and 20% WO were more effective than VC in promoting hair growth, especially 20% WO. Furthermore, in hematoxylin and eosin-stained skin tissue, an increase in the number of hair follicles and subcutaneous tissue thickness was observed with 20% WO. Whole-genome transcriptomic analysis also showed that 20% WO may have lower stress- and inflammation-related responses than 3% MXD. Therefore, whale oil can be expected to be used as a safe hair growth agent.

Bald thigh syndrome in sighthounds

Project description:Bald thigh syndrome is a common hair loss disorder in sighthounds. The overall goal of our study was to identify the cause of bald thigh syndrome and the pathological changes associated with it. We approached this aim by comparing skin biopsies and hair shafts of affected and control dogs microscopically as well as by applying high-throughput technologies such as genomics, transcriptomics and proteomics. While the histology is rather unspecific in most cases, trichogram analysis and scanning electron microscopy revealed severe structural abnormalities in hair shafts of affected dogs. This finding is supported by the results of the transcriptomic and proteomic profiling of skin biopsies and hair shafts, respectively, where genes and proteins important for differentiation of the inner root sheath and the assembly of a proper hair shaft were downregulated. Transcriptome profiling of skin biopsies revealed a downregulation of genes encoding 23 hair shaft keratins and 51 keratin associated proteins, as well as desmosomal cadherins and several actors of the BMP signaling pathway, which is important for hair shaft differentiation. To identify differentially expressed proteins in structural abnormal hair shafts, we performed nLC-MS/MS- based proteomic analysis of fractured hair shafts of four dogs with bald thigh syndrome (Greyhounds, n=3, Whippet, n=1) and intact telogen hair shafts of four control dogs (Greyhounds, n=3, Whippet= n=1) plucked on the thighs. Decreased expression of keratin 71 and desmocollin 2 on the mRNA level in skin biopsies corresponded with a reduced protein expression in the hair shafts of affected dogs.

Folding Keratin Gene Clusters During Skin Specification

Project description:Regional specification is critical for skin development, regeneration and evolution. The contribution of epigenetics in this process remains unknown. Here using avian epidermis we find two major strategies regulate β-keratin gene clusters. 1) Over the body, macro-regional specificities (scales, feathers, claws, etc) established by typical enhancers control five sub-clusters located within the epidermal differentiation complex on chromosome 25; 2) Within a feather, micro-regional specificities are orchestrated by temporo-spatial chromatin looping of the feather β-keratin gene cluster on chromosome 27. Analyses suggest a 3-factor model for regional specification: competence factors (e.g., AP1) make chromatin accessible, regional specifiers (e.g., Zic1) target specific genome regions, and chromatin organizers (e.g., CTCF, SATB2) establish looping configurations. Gene perturbations disrupt morphogenesis and histo-differentiation. This chicken skin paradigm advances our understanding of how regulation of big gene clusters can set up a two-dimensional body surface map.
