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

ABSTRACT: 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.

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.

Glucocorticoid promotes fatty acids metabolism in hypertrophic scar tissues and fibroblasts via the microRNA

Project description:Hypertrophic scar (HS) is a skin lesion due to abnormal wound healing after skin injury; histologically, HS is characterized by deposition of excessive amounts of the extracellular matrix and collagen produced by wound healing-induced proliferative fibroblasts. Clinically, HS management includes surgical resection of HS, topical glucocorticoid therapy or drug injections, pressure therapy, fractional carbon dioxide laser therapy, and cryotherapy. In terms of non-surgical therapy, glucocorticoids (like Triamcinolone acetonide, a synthetic corticosteroid medication used topically to treat various skin conditions) was able to effectively inhibit HS formation safely for decades. The effects of glucocorticoids may either be due to its anti-inflammatory, anti-allergenic and immunomodulatory effects or activate fatty acids metabolism by promotion of lipid accumulation in fibroblasts. However, it is no clear why and how glucocorticoids-upregulated fatty acid metabolisms benefit in HS treatment and prevention.And it remains to be defined how altered microRNAs regulated-fatty acid metabolism involved in pathological scars.

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.
