Differential N6-methyladenosine(m6A) modification in hypertrophic scar v.s. normal skin

Project description:N6-methyladenosine (m6A) is the most prevalent internal modification in eukaryotes. Here, m6A-mRNA and lncRNA transcriptomes were profiled for HS and full-thickness normal skin (NS) tissues using human m6A-mRNA and lncRNA epitranscriptomic microarray. These data exhibited 5838 differentially m6A methylated transcripts (4706 mRNAs, 1132 lncRNAs) between HS and NS tissues. Of note, most of them (about 94%) were hypermethylated. And 3197 differentially expressed mRNAs (1466 upregulated and 1731 downregulated) were obtained by microarray. Conjoint analysis of differentially methylated and differentially expressed transcripts screened 815 transcripts (675 hyper-up, 140 hypo-down). Among them, IFNGR1 (ENST00000367739) and IL37 (ENST00000349806) are two of the most significant methylated transcripts in hyper-up and hypo-down groups. This study proposed a transcriptional regulatory network of m6A modifications on mRNA and lncRNA in human hypertrophic scar, which may bring a new clue into the development, pathogenesis, and treatment of abnormal scars.

The m6A RNA modification modulates gene expression and fibrosis-related pathways in hypertrophic scar

Project description:Purpose: To systematically analyze the overall m6A modification pattern in hyperplastic scars (HS). Methods: The m6A modification patterns in HS and normal skin (NS) tissues were described by m6A sequencing and RNA sequencing, and subsequently bioinformatics analysis was performed. The m6A-related RNA was immunoprecipitated and verified by real-time quantitative PCR. Results: The appearance of 14,791 new m6A peaks in the HS sample was accompanied by the disappearance of 7,835 peaks. The unique m6A-related genes in HS were thus associated with fibrosis-related pathways. We identified the differentially expressed mRNA transcripts in HS samples with hyper-methylated or hypo-methylated m6A peaks. Conclusion: This study is the first to map the m6A transcriptome of human HS, which may help clarify the possible mechanism of m6A-mediated gene expression regulation.

METTL3 Facilitates Hypertrophic Scar Fibrosis by Promoting pri-miRNA-31 Maturation and ZBTB20 Silencing in m6A-dependent Manner [MeRIP-Seq]

Project description:To clarify the role of METTL3-mediated m6A modification in hypertrophic scars (HS), we conditionally knocked out the m6A methyltransferase METTL3 in HS-derived dermal fibroblasts (HSFBs). We then performed MeRIP-seq analysis on HSFBs.

Epigenome analysis of normal skin and hypertrophic scar samples

Project description:Hypertrophic scarring (HS) is characterized by excessive extracellular matrix deposition, matrix metalloprotein gene activation, and fibroblast invasive growth. However, the methylation level of hypertrophic scarring is poorly understood. Genome wide DNA methylation profiling of normal skin and hypertrophic scar. The Illumina Infinium Methylation EPIC BeadChip (850K) was used to obtain DNA methylation profiles across approximately 853,307 CpGs in liquid based scar samples. Samples included 6 normal skin, and 6 hypertrophic scar.

Gene Expression in Three Early Human Hypertrophic Scar Samples

Project description:The goal was to obtain expression data from the deep cones in early human hypertrophic scars to be used to confirm expression data obtained in a porcine model. Three samples of early human hypertrophic scar were obtained and processed with the Affymetrix Human GeneChip® Human Genome U133 plus 2.0. Sample demographics were Black 2, White 1; upper extremity 2, neck 1; times since injury 6.7 months and 10.8 months; and patient ages were 19 and 54.
