Guanglei Hu, Weihui Zeng, Yumin Xia
TWEAK (tumor necrosis factor-related weak inducer of apoptosis), a member of the tumor necrosis factor superfamily, acts on cells by binding to its only receptor named Fn14 (fibroblast growth factor-inducible 14). Their engagement activates a number of intracellular signal transduction cascades and consequently leads to cell death, proliferation, migration, or survival depending on the cellular contexts. Studies have indicated that the expression of TWEAK and Fn14 is upregulated in many solid tumors compared with healthy tissues...

Porcine conceptuses secrete pregnancy-recognition signals (estrogens, including estradiol-17β) that inhibit luteolysis, thereby prolonging progesterone production by corpora lutea. The supportive mechanism by which the conceptus also inhibits luteolysis is by shifting endometrial prostaglandin (PG) synthesis to luteoprotective PGE2. Progesterone stimulates endometrial production of factors that are essential for conceptus development. Priming the uterus by progesterone and loss of progesterone receptors from the uterine epithelium by D1ay 10-12 after estrus are key for achieving endometrial receptivity for implantation...

Excessive alcohol consumption is the most common cause of liver disease in the world. Chronic alcohol abuse leads to liver damage, liver inflammation, fibrosis and hepatocellular carcinoma. Inflammatory cytokines, such as tumor necrosis factor-α and interferon-γ, induce liver injury, which leads to the develo-pment of alcoholic liver disease (ALD). Hepatoprotective cytokines, such as interleukin (IL)-6 and IL-10, are also associated with ALD. IL-6 improves ALD via the activation of STAT3 and the subsequent induction of a variety of hepatoprotective genes in hepatocytes...

The search for the etiologic agent for Kaposi sarcoma (KS) led to the discovery of Kaposi sarcoma associated herpesvirus (KSHV) in 1994. KSHV, also called human herpesvirus-8 (HHV-8) has since been shown to be the etiologic agent for several other tumors and diseases, including primary effusion lymphoma (PEL), an extracavitary variant of PEL, KSHV-associated diffuse large B-cell lymphoma, a form of multicentric Castleman disease (MCD), and KSHV inflammatory cytokine syndrome (KICS). KSHV encodes several genes that interfere with innate and specific immunity, thwart apoptosis, enhance cell proliferation and cytokine production, and promote angiogenesis, and these play important roles in the disease pathogenesis...

Mast cells, accumulate in the stroma surrounding certain tumors and take part to the inflammatory reaction occurring at the periphery of the tumor. Mast cell-secreted angiogenic cytokines facilitate tumor vascularization not only by a direct effect but also by stimulating other inflammatory cells of the tumor microenvironment to release other angiogenic mediators. An increased number of mast cells have been demonstrated in angiogenesis associated with solid tumors, including breast cancer. Mast cells might act as a new target for the adjuvant treatment of breast cancer through the selective inhibition of angiogenesis, tissue remodeling and tumor promoting molecules, allowing the secretion of cytotoxic cytokines and preventing mast cell mediated immune-suppression...

C-X-C motif chemokine ligand 8 (CXCL-8) promotes cell homing and angiogenesis. However, under hypoxic conditions, the role of CXCL-8 in the homing of human umbilical vein endothelial cells (HUVECs), and its effect on the healing of skin ulcers caused by ischemia and hypoxia remain unknown. In the current study, assays measuring cell proliferation, in vitro angiogenesis and cell migration were performed to evaluate alterations in the proliferation, angiogenic capacity and chemotaxis of HUVECs treated with CXCL-8 protein and/or an Akt inhibitor (AZD5363 group) under hypoxic conditions...

Endothelium toxicity has been involved in early endothelial dysfunction to show the pathogenesis of multiple cardiovascular disease that shows atherosclerosis and its complications. Saturated free fatty acids are the main inducing factors of endothelial cell apoptosis and inflammatory cytokines. In humans, stearoyl-CoA desaturase 1 (SCD-1) is a restriction step to saturation to unsaturated fatty acid desaturation, which plays a beneficial role protecting endothelial cells against lipotoxicity. Δ-17 fatty acid desaturase (FAD) is a newly identified FAD which shares 55% identity at the amino acid level with SCD-1...

Anti-angiogenesis has emerged as a standard of care for metastatic renal cell carcinoma. However, long-lasting efficacy is seldom reached, and evasive resistance eventually occurs under anti-angiogenic tyrosine kinase inhibitor (TKI) therapy. To establish new therapeutic strategies, investigating the molecular mechanism of resistance is critically important. In our study, human umbilical vascular endothelial cells (HUVECs) were incubated with TKI treatment in conditioned medium derived from renal cancer cells (RCCs) to demonstrate cell viability...

Ischemic stroke is the leading cause of disabilities worldwide. MicroRNA-377 (miR-377) plays important roles in ischemic injury. The present study focused on the mechanisms of miR-377 in protecting ischemic brain injury in rats. Cerebral ischemia was induced by middle cerebral artery occlusion (MCAO) in rats. Primary rat microglial cells and brain microvascular endothelial cells (BMECs) were exposed to oxygen-glucose deprivation (OGD). The concentrations of cytokines (TNF-α, IL-1β, IL-6, IFN-γ, TGF-β, MMP2, COX2 and iNOS) in the culture medium were measured by specific ELISA...

Pre-eclampsia (PE) is characterized by an exaggerated systemic inflammatory response and generalized endothelial dysfunction. We have recently demonstrated that fibrinogen, an endogenous ligand of Toll-like receptor (TLR) 4, activates monocytes from women with pre-eclampsia (Al-ofi et al., 2014). Using an experimental co-culture model of primary human monocytes (derived from 9 women with PE (GA=33.18±5.8) and 9 normotensive pregnant women, NP (GA=33.15±4.0)) and human umbilical venous endothelial cells (HUVECs), we compared the effects of fibrinogen and lipopolysaccharide (LPS, bacterial ligand to TLR4) on the expression levels of inflammatory cytokines (IL-6 and IL-1β), chemokines (IL-8 and MCP-1), and anti-angiogenic factor (soluble fms-like tyrosine kinase-1,sFLT-1), as well as the soluble vascular cell adhesion molecule-1 (sVCAM-1)...

Millions of patients around the world suffer minor or major extremity amputation due to progressive wound healing complications of chronic or infected wounds, the therapy of which remains a challenge. One emerging therapeutic option for the treatment of these complicated wounds is the local application of an autologous thrombocytes concentrate lysate (e.g. platelet-released growth factors ((PRGF)) or Vivostat PRF(®)) that contains a multitude of chemokines, cytokines and growth factors and is therefore supposed to stimulate the complex wound healing process...

It has been previously demonstrated that the bi-directional transporter Na(+)/Ca(2+) exchanger (NCX) working in the reverse (Ca(2+)-influx) - mode promotes the activation of ERK1/2 in response to the key pro-angiogenic cytokine VEGF in human endothelial cells (ECs). However, the molecular event(s) that elicit NCX reversal in VEGF-stimulated ECs remain unclear. Here we investigated whether Na(+) influx via the diacylglycerol (DAG) - activated non-selective cation channel TRPC3 was functionally associated with NCX and whether its activity was required for VEGF-induced ERK1/2 activation and angiogenesis...

Autologous adipose tissue or adipose tissue with additive adipose-derived mesenchymal stem cells (ADSCs) is used in the breast reconstruction of breast cancer patients who undergo mastectomy. ADSCs play an important role in the angiogenesis and adipogenesis, which make it much better than other materials. However, ADSCs may promote residual tumor cells to proliferate or metastasize, and the mechanism is still not fully understood. In this study, we demonstrated that human ADSCs (hADSCs) could facilitate tumor cells growth after co-injection with MCF7 and ZR-75-30 breast cancer cells (BCCs) by promoting angiogenesis, but hADSCs showed limited effect on the growth of MDA-MB-231 BCCs...

Tumors routinely attract and co-opt macrophages to promote their growth, angiogenesis and metastasis. Macrophages are also the key effector cell for monoclonal antibody (mAb) therapies. Here we report that the tumor microenvironment creates an immunosuppressive signature on tumor-associated macrophages (TAM) which favors expression of inhibitory rather than activating Fcγ receptors (FcγR), thereby limiting the efficacy of mAb immunotherapy. We assessed a panel of TLR and STING agonists (a) for their ability to reprogram macrophages to a state optimal for mAb immunotherapy...

INTRODUCTION: Psoriasis is a chronic inflammatory skin disease characterized by epidermal hyperproliferation, abnormal differentiation and inflammatory infiltration in the dermis. The dermal microvascular expansion associated with abnormal orientation and dilatation of capillaries in the biopsies of the psoriatic skin suggest that the disease is dependent on angiogenesis. AIM: To analyze and compare the immunohistochemical expression of angiogenic factors - Vascular Endothelial Growth Factor (VEGF), von Willebrand Factor (vWF) and CD 34 in skin biopsies of psoriasis cases with control skin samples; and to correlate the expression of angiogenic factors with Psoriasis Area and Severity Clinical Index (PASI SCORE)...

BACKGROUND AIMS: Adipose tissue has therapeutic potential for spinal cord injury (SCI) because it contains multipotent cells known as adipose-derived stem/stromal cells (ASCs). In this study, we attempted intravenous ASC transplantation in rats with SCI to examine the effect on functional recovery. METHODS: ASCs (2.5 × 10(6)) were intravenously infused into SCI rats, after which hindlimb motor function was evaluated. Distribution of transplanted ASCs was investigated and growth factor/cytokine levels were determined...

Background -Thioredoxin-1 (TRX1), a ubiquitous 12 kDa protein, exerts anti-oxidant and anti-inflammatory effects. In contrast, the truncated form, called TRX80, produced by macrophages induces up-regulation of pro-inflammatory cytokines. TRX80 also promotes the differentiation of mouse peritoneal and human macrophages toward a pro-inflammatory M1 phenotype. Methods -TRX1 and TRX80 plasma levels were determined using specific ELISA. ADAM-17 and ADAM-10 activities were measured using respectively SensoLyte® 520 ADAM10 Activity Assay Kit *Fluorimetric* and InnoZyme™ TACE Activity Kit...

The wound healing process requires enough blood to supply nutrients and various growth factors to the wound area. However, chronic wounds such as diabetic skin ulcers have limited regeneration due to a lack of cellular and molecular signals because of a deficient blood flow. Mesenchymal stem cells (MSCs) are known to provide various factors including growth factors, cytokines and angiogenic mediators. Although MSCs have great therapeutic potential, their transplantation has many obstacles including the time required to culture the cells, the invasiveness of the procedure and limited stem cell sources...
