Suppressed inflammatory gene expression during human hypertrophic scar compared to normotrophic scar formation.
Amsterdam, Netherlands. In Exp Dermatol, 02 Jun 2015
In this study, we compared the expression of genes involved in inflammation, angiogenesis and extracellular matrix (ECM) formation and also macrophage infiltration in biopsies obtained before and up to 52 weeks after standard surgery in 5 patients who developed HTscar and 6 patients who developed It was found that HTscar formation coincided with a prolonged decrease of expression of inflammatory genes (TNFα, IL-1α, IL-1RN, CCL2, CCL3, CXCL2, CXCR2, C3 and IL-10) and an extended increased expression of ECM related genes (PLAU, Col3A1, TGFβ3).
Inhibition of Tanshinone IIA, Salvianolic Acid A and Salvianolic Acid B on Areca Nut Extract-Induced Oral Submucous Fibrosis in Vitro.
Shantou, China. In Molecules, Dec 2014
The results showed that Tan-IIA, Sal-A and Sal-B could significantly inhibit the ANE-stimulated abnormal viability and collagen accumulation of mice oral mucosal fibroblasts (MOMFs), inhibit the transcription of procollagen gene COL1A1 and COL3A1, increase MMP-2/-9 activity, decrease TIMP-1/-2 expression and inhibit the transcription and release of CTGF, TGF-β1, IL-6 and TNF-α; Tan-IIA, Sal-A and Sal-B also inhibited the ANE-induced activation of AKT and ERK MAPK pathways in MOMFs and the activation of TGF-β/Smads pathway in HaCaT cells.
Heritable thoracic aortic disorders.
In Curr Opin Cardiol, 2014
RECENT FINDINGS: A classification scheme based on the gene is emerging, those that affect primarily the extracellular matrix (e.g., FBN1, COL3A1), TGF-β signaling (e.g., TGFBR1, TGFB2), or vascular smooth muscle cell contractility (e.g., ACTA2, MYH11).
