Long noncoding RNA (lncRNA) expression profiles of hypertrophic scar fibroblasts treated with glucocorticoids under mechanical stretch environment

After disruption of the skin, fibroblasts along wound edges are constantly exposed to high levels of stress, resulting in increased collagen synthesis and decreased apoptosis. Emerge evidences shows that, the hypertrophic scars tissue fibrosis phenomena are original from the intrinsic cellular mechanical stretch. Traditional glucocorticoids on hypertrophic scarring have been performed for 30 years, utilizing for their anti-inflammatory, anti-allergenic and immunomodulatory effects and for their well-established, pro-apoptotic effects on hematological malignancies. To explore effects of glucocorticoid triamcinolone acetonide (TA) for responses to mechanical stress in hypertrophic scars fibroblasts (HSFB), we performed microarrays to explore long noncoding RNA expression. Our protocol included hypertrophic scars fibroblasts treated with glucocorticoid were seeded in the chambers and subjected to mechanical stretch. Paired HSFBs in the control groups were treated with solvent and subjected to mechanical stretch. LncRNA expression profiles were evaluated by customized Agilent human microarray (OE Biotech Human ceRNA Microarray, Design ID:086188).
