Peritoneal fibrosis (PF) is a serious complication in various clinical settings, but the mechanisms driving it remain to be fully determined. Connective tissue growth factor (CTGF) is known to regulate fibroblast activities. We therefore examined if CTGF inhibition has anti-fibrotic effects in PF. PF was induced by repetitive intraperitoneal injections of chlorhexidine gluconate (CG) in mice with type I pro-collagen promoter-driven green fluorescent protein (GFP) expression to identify fibroblasts. FG-3019, an anti-CTGF monoclonal antibody, was used to inhibit CTGF...

BACKGROUND: Juvenile nasopharyngeal angiofibroma (JNA) is a benign tumor that presents in adolescent males. Although surgical excision is the mainstay of treatment, recurrences complicate treatment. There is a need to develop less invasive approaches for management. JNA tumors are composed of fibroblasts and vascular endothelial cells. We identified fibroblast growth factor receptor (FGFR) and vascular endothelial growth factor (VEGF) expression in JNA-derived fibroblasts. FGFR influences fibroblast proliferation and VEGF is necessary for angiogenesis...

BACKGROUND: Neovascularization, also known as angiogenesis, is the process of capillary sprouting from pre-existing blood vessels. This physiological process is a hallmark event in normal embryonic development as blood vessels generally supply both oxygen and nutrients to the cells of the body. Any disruption in this process can lead to the development of various chronic diseases, including cancer. In cancer, aberrant angiogenesis plays a prominent role in maintaining sustained tumor growth to malignant phenotypes and promoting metastasis...

IL-33 is a newly discovered member of the IL-1 family and has been identified as a potent inducer of Th2 type immunity. Emerging evidence imply that IL-33 may also act as an alarm to alert the immune system when released by epithelial barrier tissues during trauma or infection. In this study, we further investigate the potential efficacy of IL-33 on dermal wound healing in streptozotocin-induced diabetic mice. A full-thickness skin wound was generated on the back of diabetic mice and treated with IL-33 or vehicle topically...

INTRODUCTION: Nintedanib is a multi-tyrosine kinase receptor inhibitor recently approved for treatment of idiopathic pulmonary fibrosis. Although angiogenesis is a key process involved in airway structural changes in patients with bronchial asthma, the effect of nintedanib targeting the angiokinase pathway on airway inflammation and remodeling has not been evaluated. METHODS: We used a 3-month ovalbumin (OVA) challenge mouse model of airway remodeling. Nintedanib was orally administrated during the challenge period, and the effects were examined based on the percentage of airway inflammatory cells, airway hyper-reactivity (AHR), peribronchial goblet cell hyperplasia, total lung collagen and smooth muscle area...

Soft tissue sarcomas (STS) are rare malignant tumors. Unfortunately, the first-line doxorubicin-based treatment has not been improved since the 1970s. Platelet-derived growth factor (PDGF) receptor alpha (PDGFR-α) and its ligands are co-expressed in many types of cancer, including sarcomas. They are involved in stimulating growth and regulating stromal-derived fibroblasts and angiogenesis. PDGFR-α and its ligand may play an important role in tumorigenesis and be a potential target in the treatment of sarcomas...

BACKGROUND: Angiogenesis is a process of new vessel formation originating from the already present vascular network. It plays an important role in the growth and spreading of malignancies, including brain tumours. Process of angiogenesis is characterised by increased expression of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF), and release of their soluble forms into circulation. OBJECTIVES: The aim of the study was to evaluate serum levels of VEGF and bFGF in children with malignant and benign brain tumours...

Effectively stimulating angiogenesis is great challenge in wound care management. It's necessary to develop a new wound dressing with angiogenic capacity. Therefore, strontium loaded SF/SA blend films were prepared as a potential wound dressing material, and their physicochemical and bioactive properties were evaluated. The strontium loaded SF/SA blend films (especially the strontium loaded SF/SA blend films prepared by treating with 5mg/ml Sir solution) could meet the needs of a wound dressing such as water absorption, water vapor transmission rate, mechanical properties and fibroblasts-cytocompatibility...

Arylurea derivatives, an important class of small molecules, have received considerable attention in recent years due to their wide range of biological applications. Various molecular targeted agents with arylurea scaffold as potential enzyme/receptor inhibitors were constructed with the successful development of sorafenib and regorafenib. This review focuses on those arylureas possessing anti-cancer activities from 2010 to date. According to their different mechanisms of action, these arylureas are divided into the following six categories: (1) Ras/Raf/MEK/ERK signaling pathway inhibitors; (2) tumor angiogenesis inhibitors, their targets include vascular endothelial growth factor receptors (VEGFRs), fibroblast growth factor receptors (FGFRs), platelet-derived growth factor receptors (PDGFRs), epidermal growth factor receptors (EGFRs), insulin-like growth factor 1 receptor (IGF-1R), Fms-like tyrosine kinase 3 (FLT3), c-Kit, MET, and Smoothened (Smo); (3) PI3K/AKT/mTOR signaling pathway inhibitors; (4) cell cycle inhibitors, their targets include checkpoint kinases (Chks), cyclin-dependent kinases (CDKs), Aurora, SUMO activating enzyme 1 (SUMO E1), tubulin, and DNA; (5) tumor differentiation, migration, and invasion inhibitors, their targets include matrix metalloproteinases (MMPs), LIM kinase (Limk), nicotinamide phosphoribosyltransferase (Nampt), and histone deacetylase (HDAC); (6) arylureas from the rational modification of natural products...

Unlike for adenocarcinomas of the lung, no molecular targeted therapies have yet been developed for squamous cell lung cancers, because targetable oncogenic aberrations are scarce in this tumor type. Recent discoveries have established that the fibroblast growth factor (FGF) signaling pathway plays a fundamental role in cancer development by supporting tumor angiogenesis and cancer cell proliferation via different mechanisms. Through comprehensive genomic studies, aberrations in the FGF pathway have been identified in various tumor types, including squamous cell lung cancer, making FGF receptor (FGFR) a potentially druggable target in this malignancy...

Deficiency of the extracellular matrix (ECM) protein latent transforming growth factor beta (TGFβ) binding protein 4 (LTBP-4) results in lack of intact elastic fibers, which leads to disturbed pulmonary development and lack of normal alveolarization in humans and mice. Formation of alveoli and alveolar septation in pulmonary development requires the concerted interaction of extracellular matrix proteins, growth factors like TGFβ, fibroblasts and myofibroblasts to promote elastogenesis as well as vascular formation in the alveolar septae...

Breast cancer is the most commonly diagnosed malignant tumor in women worldwide and contributes significantly as the primary cause of female cancer related mortality. Hence, research is focused on discovering new and effective treatment targets. The breast tumor microenvironment (TME) comprising of recruited host stromal cells and tumor cells, has recently emerged as an important player in tumor progression, with the potential for future treatment. The TME comprises immune system elements (such as macrophages and lymphocytes), cells composing blood vessel, fibroblast, myofibroblast, mesenchymal stem cells, adipocytes and extracellular matrix (ECM)...

The tumor microenvironment (TME) is a relevant target for novel biological therapies. MV-m-uPA and MV-h-uPA are fully retargeted, species-specific, oncolytic measles viruses (MVs) directed against murine or human urokinase receptor (PLAUR/uPAR), expressed in tumor and stromal cells. The effects of stromal selective targeting by uPAR retargeted MVs were investigated. In vitro infection, virus-induced GFP expression and cytotoxicity by MV-h-uPA and MV-m-uPA were demonstrated in human and murine cancer cells and cancer associated fibroblasts (CAFs) in a species-specific manner...

Wnts are secreted glycoproteins that regulate stem cell self-renewal, differentiation, and cell-to-cell communication during embryonic development and in adult tissues. Bone marrow mesenchymal stem cells (BM-MSCs) have been shown to stimulate dermis repair and regeneration; however, it is unclear how BM-MSCs may modulate downstream Wnt signaling. While recent reports implicate that Wnt ligands and Wnt messenger RNAs (such as Wnt4) exist within the interior compartment of exosomes, it has been debated whether or not Wnts exist on the exterior surface of exosomes to travel in the extracellular space...

Lesions associated with medication-related osteonecrosis of the jaws (MRONJ) are refractory to different treatment approaches. Hence, auxiliary approaches capable of improving patient outcomes should be explored. Leukocyte- and platelet-rich fibrin (LPRF) is a second-generation platelet concentrate (natural autologous fibrin matrix). It shows anti-infectious activity through immune regulation and accelerates the angiogenesis and multiplication of fibroblasts and osteoblasts; in consequence, it stimulates soft tissue healing and prevents exposure of the alveolar bone in the oral cavity...

Fibroblast growth factor receptors (FGFRs) are a family of receptor tyrosine kinases containing three domains: an extracellular receptor domain, a single transmembrane helix, and an intracellular tyrosine kinase domain. FGFRs are activated by fibroblast growth factors (FGFs) as part of complex signal transduction cascades regulating angiogenesis, skeletal formation, cell differentiation, proliferation, cell survival, and cancer. We have developed the first recombinant expression system in E. coli to produce a construct of human FGFR2 containing its transmembrane and extracellular receptor domains...
