Genes affected

PTX3 (HGNC:9692): (pentraxin 3) This gene encodes a member of the pentraxin protein family. The expression of this protein is induced by inflammatory cytokines in response to inflammatory stimuli in several mesenchymal and epithelial cell types, particularly endothelial cells and mononuclear phagocytes. The protein promotes fibrocyte differentiation and is involved in regulating inflammation and complement activation. It also plays a role in angiogenesis and tissue remodeling. The protein serves as a biomarker for several inflammatory conditions. [provided by RefSeq, Jun 2016]

PTX3 links:

VEPH1 (HGNC:25735): (ventricular zone expressed PH domain containing 1) Predicted to enable phosphatidylinositol-5-phosphate binding activity. Involved in negative regulation of SMAD protein signal transduction and negative regulation of transforming growth factor beta receptor signaling pathway. Predicted to be active in plasma membrane.
