Expression data from mouse skin

ABSTRACT: Winged bean (WB), Psophocarpus tetragonolobus, is a tropical legume, the potential of which is not yet been understood. We found that a 5 week-oral administration of WB seed extract inhibited wrinkle formation induced by repeated tape stripping (TS), which is a model of lichenification in human chronic eczematous dermatitis. To elucidate mechanism of the effect of WB on this model, we applied microarray analysis. Skin barrier was disrupted by repeated application and removal (tape stripping; TS) of cellophane tape on the dorsal skin of the left side. This procedure was started after 1 week-administration of winged bean (WB) extract, and was conducted 3 times per week for 4 weeks. Dorsal skin samples from three experimental groups were used for microarray experiment. These groups were the non-TS (NT), TS, and TS with oral administration of WB extract (TS/WB). The DNA microarray experiment was performed using Affymetrix Mouse Genome 430 2.0 Array.

Winged bean (WB), Psophocarpus tetragonolobus, is a tropical legume, the potential of which is not fully understood. We found that 5-week oral administration of a WB seed extract inhibited wrinkle formation induced by repeated tape stripping (TS) as a model of lichenification in human chronic eczematous dermatitis. To elucidate the mechanism of the effect of WB on this model, we applied microarray analysis. Hierarchical clustering revealed that each experimental group formed a distinct cluster, ...[more]

Comparison of Tape-Stripping Platforms as Non-Invasive Solutions for Skin Biomarker Discovery

Project description:Use of tape stripping for the collection of stratum corneum is a versatile and reliable procedure for the evaluation of the human skin health, including assessments of the skin barrier function, microbial content, and disease biomarkers. The tape stripping procedure is widely referenced; however, the number and type of tapes required for sample collection vary considerably, and the lack of standardized sampling, processing and normalization protocols complicate data comparison and interpretation. We have compared the performances of two commonly used non-invasive skin sampling platforms by collecting skin tissue from 34 healthy volunteers and applying standardization throughout the workflow, from sampling to data analysis. Our results showed significant differences in the amounts of tissue collected per tape, erythema levels, RNA and protein yields. RNA extracts from both platforms were suitable for sequencing; comparable input and quality of reads were produced for both test groups, however significant differences were found in the percentage of uniquely mapped reads and detected genes. This data highlights processing optimization as an important step in maximizing the efficiency of biomolecule extraction from tape strips and further presents a tape stripping method suitable for fast, efficient, and non-invasive epidermal tissue collection applicable to skin biomarker discovery.

Profilig the Atopic Dermatitis Epidermal Transcriptome by Tape Stripping and BRB-seq

Project description:Tape stripping has recently gained use for the study of the transcriptome of atopic dermatitis (AD), a common inflammatory skin disorder characterized by a defective epidermal barrier and perturbated immune response. Here, we performed BRB-seq (a low cost, multiplex-based, transcriptomic profiling technique) to study the epidermal transcriptome of AD patients and healthy controls from tape stripped skin samples.

The stratum corneum transcriptome in atopic dermatitis can be assessed by tape stripping

Project description:Background: Skin biopsies represent a gold standard in skin immunology and pathology but can cause pain and induce scarring. Non-invasive techniques will facilitate study recruitment of e.g. patients with pediatric atopic dermatitis (AD), hand eczema or facial dermatitis. Objective: By RNA sequencing, we examined whether the stratum corneum transcriptome in AD skin can be assessed by tape stripping, as compared to the epidermal transcriptome of AD in skin biopsies. To make the procedure clinically relevant tape strips were stored and shipped at room temperature for up to 3 days. Methods: Nine adult Caucasian AD patients and three healthy volunteers were included. Tape samples were collected from non-lesional and lesional skin. Biopsies were collected from lesional skin and were split into epidermis and dermis. Total RNA was extracted, and shotgun sequencing was performed. Results: Shotgun sequencing could be performed on skin cells obtained from two consecutive tape strips which had been stored and shipped at room temperature for up to three days. The most prominent differences between the tape strip and biopsy derived transcriptome were due to structural genes, while established molecular markers of AD, including CCL17, CCL22, IL17A and S100A7-S100A9, were also identified in tape strip samples. Furthermore, the tape strip derived transcriptome showed promise in also analysing the skin microbiome. Conclusion: Our study shows that the stratum corneum (SC) transcriptome of AD can be assessed by tape stripping the skin, supporting that this method may be central in future skin biomarker research.

P. syringae pv. phaseolicola NPS3121 responses to bean leaf extract

Project description:Many genes involve in pathogenicity and virulence are induced only in plant or in the presence of host components. Bean leaf extract was obtained from healthy bean leaves. In this work we investigated the effect of bean leaf extract on the transcriptomic profile of the bacterium, when grown at low temperature in minimal medium with or without extract from healthy bean leaves.

Topical Application of Nano-sized Graphene Oxide Cream Ameliorates Acute Skin Inflammation in Mice

Project description:We have previously shown that nano-sized graphene oxide (NGO) displays anti-inflammatory activities against natural killer T (NKT) cell-mediated sepsis. To address whether NGO could be applied to treat acute skin inflammation. We developed a conventional skin Cetaphil® cream containing NGO (NGO cream) for topical application to skin lesions and investigated its therapeutic efficacy by employing the tape-stripping-induced acute skin inflammation model. Topical application of NGO cream to the wounded area significantly reduced skin lesions compared with the control cream. Moreover, NGO cream treatment prevented the tape-stripping-elicited infiltration of and IL1β production by skin neutrophils and dendritic cells (DCs). Furthermore, such anti-inflammatory effects of NGO cream were attributed to decreased infiltration of IL12-producing DCs and IFNγ-producing cells (e.g., CD4+ T, CD8+ T, γδ T, NK, and NKT cells) into the skin. In addition, topical NGO cream administration enhanced the expression of suppressive molecules such as FR4 on skin regulatory T cells. Through RNA sequencing analysis, we found that the preventive effect of NGO cream on acute skin inflammation may be correlated with the activation of keratinocytes located in the epidermis. Our results support NGO cream as a therapeutic option to control acute skin inflammation.

Gene expression analysis in liver collected from mice administered non-toxic, toxic, or severely toxic LNA sequences

Project description:Development of LNA gapmers, antisense oligonucleotides used for efficient inhibition of target RNA expression, is limited by non-target mediated hepatotoxicity issues. In the present study, we investigated hepatic transcription profiles of mice receiving non-toxic and toxic LNA gapmers after a single and repeat administration. To understand the mechanism of LNA gapmer-induced heptotoxicity in mice, we investigated the transcription profiles of liver RNA isolated from mice receiving non-toxic sequence (NTS-1), toxic sequence (TS-2), or severely toxic sequence (HTS-3) of LNA gapmers at 25 mg/kg (dose volume of 10 mL/kg) at 8, 16, or 72 hrs after a single administration (by subcutaneous injection ) using microarray analysis. We also investigated the transcription profiles of liver RNA isolated from mice receiving non-toxic sequence (NTS-1) or toxic sequence (TS-2) of LNA gapmers at 25 mg/kg (dose volume of 10 mL/kg) at 2 weeks after repeated administration (by subcutaneous injection ) using microarray analysis.
