Via their capacities for proliferation and synthesis of matrix proteins such as collagen, fibroblasts are key effectors in the pathogenesis of fibrotic disorders such as idiopathic pulmonary fibrosis. Prostaglandin E(2) (PGE(2)) potently inhibits these functions in lung fibroblasts through receptor ligation and production of the second messenger cAMP, but the downstream pathways mediating such ...

Dysregulation of fibroblast growth factor receptors ( FGFRs ) has been implicated in several human malignancies, including urothelial carcinoma. In carcinoma, the oncogenic role mutated FGFR is mediated by RAS-mitogen-activated protein kinase pathway, resembling effects observed with activated HRAS . Activating somatic mutations FGFR3 are clustered three hotspots exons 7, 10 and 15, almost alwa...

We previously reported that basic fibroblast growth factor (FGF-2) stimulates the release of vascular endothelial growth factor (VEGF) via p44/p42 mitogen-activated protein (MAP) kinase and stress-activated protein kinase/c-Jun N-terminal kinase (SAPK/JNK) in osteoblast-like MC3T3-E1 cells and that FGF-2-activated p38 MAP kinase negatively regulates VEGF release. In addition, p70 S6 kinase acti...

BACKGROUND: Bone Morphogenetic Protein Receptor II (BMPR2) deficiency is associated with the pathologic development of pulmonary vascular changes in Pulmonary Arterial Hypertension (PAH). Fibroblast most abundant cell vascular. However, there only a little information regarding effect BMPR2 fibroblast. This study aims to understand fibroblasts.METHODS: applied CRISPR/Cas9 technique edit BMPPR2 ...

Increased Src activity has been associated with the pathogenesis of renal tumors and some glomerular diseases, but its role in renal interstitial fibrosis remains elusive. To evaluate this, cultured renal interstitial fibroblasts (NRK-49F) were treated with PP1, a selective inhibitor of Src. This resulted in decreased expression of α-smooth muscle actin, fibronectin, and collagen I in response ...

BACKGROUND In the heart, acute injury induces a fibrotic healing response that generates collagen-rich scarring that is at first protective but if inappropriately sustained can worsen heart disease. The fibrotic process is initiated by cytokines, neuroendocrine effectors, and mechanical strain that promote resident fibroblast differentiation into contractile and extracellular matrix-producing m...
