1) Background: Keloids occur after the failure during the wound-healing process, persist 22 the inflammation and are refractory to various treatments. The pathogenesis of keloids is still 23 unclear. We previously analyzed the gene expression profiles in keloid tissue using microarray and 24 Northern blot analysis and found that HtrA1 was markedly upregulated in the keloid lesions. 25 HtrA1 is ...

keloids are aesthetically disfiguring and severely disabling. the optimal treatment remains undefined. this clinical study, evaluate the efficacy and side effects of combined topical silicone and 5-fluorouracil on the prevention of keloids. in this double blind randomized clinical trial, fifty patients with keloids were randomly allocated in two groups. the control group were treated by periles...

microRNAs (miRNAs) play a pivotal role in the regulation of cell proliferation and apoptosis in keloid scarring. Integrative analysis of the previous miRNA microarray revealed miRNA-31 was among the most frequently altered miRNAs in keloid and hypertrophic scar. Using qRT-PCR, we further validated miRNA-31 was increased in keloid tissues and keloid-derived fibroblasts. Moreover, downregulation ...

Keloid represents overgrowth of granulation tissue, which is characterized by collection of atypical fibroblasts with excessive deposition of extracellular matrix components, after skin injury, but its etiology is still largely unknown. We recently performed genome-wide association study (GWAS) of keloid and identified NEDD4 to be one of candidate molecules associated with keloid susceptibility...

BACKGROUND The pathogenesis of keloid is poorly understood. Although vigorous investigations have attempted to elucidate the mechanisms or causative factors of keloid, there are little data on why keloids are very intractable and recur easily in each patient. METHODS In an attempt to analyze the possible interaction between human mesenchymal stem cells and keloid-derived fibroblasts, the dual...

Keloid and hypertrophic scars are difficult to manage and remain a therapeutic challenge. Verapamil has shown a great potential in the management of keloid and hypertrophic scars. Comparing with conventional corticosteroid injections, verapamil could improve the appearance of keloid and hypertrophic scars, and is associated with a lower incidence of adverse effects. Is verapamil an effective al...

The keloid lesion is recognised as a spatially heterogeneous mass both in cellular and acellular composition and biological activity. Here, we have utilised a bioinformatic approach to determine whether this spatial heterogeneity is also evident at the molecular level and to identify key upstream regulators of signalling pathways enriched in the lesion in a spatially-restricted manner. Differen...

BACKGROUND Keloids are characterized by excessive collagen deposition in the dermis, in which transforming growth factor β (TGF-β)/Smad signaling plays an important role. Low-level light therapy (LLLT) is reported as effective in preventing keloids in clinical reports, recently. To date, studies investigating the effect of LLLT on keloid fibroblasts are extremely rare. OBJECTIVE We investigat...

OBJECTIVES Create a head-and-neck keloid quality of life (QOL) questionnaire. Demonstrate the reliability of the keloid-specific QOL scale according to test-retest and internal consistency standards. STUDY DESIGN Prospective cohort study. METHODS Patients presenting to a keloid clinic in a tertiary referral institution between April 2012 and February 2013 were enrolled on their first visit....

OBJECTIVES/HYPOTHESIS To generate novel insights and hypotheses in keloid development from potential master regulators. STUDY DESIGN Prospective cohort. METHODS Six fresh keloid and six normal skin samples from 12 anonymous donors were used in a prospective cohort study. Genome-wide profiling was done previously on the cohort using the Infinium HumanMethylation450 BeadChip (Illumina, San Di...
