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...

Lung malignancy is the foremost cause of cancer-related deaths globally and is frequently related to long-term tobacco smoking. Recent studies reveal that the expression of matrix metalloproteinases (MMPs) is extremely high in lung tumors compared to non-malignant lung tissue. MMPs are zinc-dependent proteases and are involved in the degradation of extracellular matrix (ECM). Several investigations have shown that MMPs manipulate the activity of non-ECM molecules, including cytokines, growth factors and receptors which control the tumor microenvironment...

Semaphorins are an essential family of guidance cues ubiquitously expressed in various organs, which play diverse developmental, homeostatic, and pathological roles. Semaphorin 3E (Sema3E), initially identified as a neuronal chemorepellent, is involved in the regulation of cell migration, proliferation, and angiogenesis. However, expression and function of Sema3E in allergic asthma has not been extensively investigated. We determined the expression of Sema3E in the airways and its effect on airway inflammation, hyperresponsiveness, and remodeling as pathological features of allergic asthma provoked by house dust mite in vivo...

BACKGROUND: Retinoblastoma (Rb) is the most common primary intraocular tumor in children. Local treatment of the intraocular disease is usually effective if diagnosed early; however advanced Rb can metastasize through routes that involve invasion of the choroid, sclera and optic nerve or more broadly via the ocular vasculature. Metastatic Rb patients have very high mortality rates. While current therapy for Rb is directed toward blocking tumor cell division and tumor growth, there are no specific treatments targeted to block Rb metastasis...

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...

Stress-induced prolonged inflammation impairs cutaneous wound healing. Exercise may inhibit this effect via an anti-inflammatory mechanism. Our aim was to investigate the effect of moderate exercise on skin wound healing in chronically stressed mice. Mice were trained five times per week on a treadmill or received no training. Mice underwent daily rotational stress from the 6(th) week until euthanasia. During the 8(th) week, two wounds were created in the dorsum and collected 10 days later. A control group only received wounds...

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...

By gating the traffic of molecules and cells across the vessel wall, endothelial cells play a central role in regulating cardiovascular functions and systemic homeostasis and in modulating pathophysiological processes such as inflammation and immunity. Accordingly, the loss of endothelial cell integrity is associated with pathological disorders that include atherosclerosis and cancer. The p38 mitogen-activated protein kinase (MAPK) cascades are major signaling pathways that regulate several functions of endothelial cells in response to exogenous and endogenous stimuli including growth factors, stress and cytokines...

Macrophages are involved in all phases of scaffold induced tissue regeneration, orchestrating the transition from an inflammatory to regenerative phenotype to guide all other cell types to complete the wound healing process when a tissue defect advances beyond the critical size. Therefore, harnessing macrophages by scaffolds is important for facilitating tissue regeneration in situ. In this work we utilized the superparamagnetic scaffold upon magnetization as a mechanostimulation platform to apply forces directly to macrophages grown in the scaffold, aiming to figure out whether the functions of macrophages related to bone tissue regeneration can be mechanomodulated and to elucidate the underlying mechanisms...

Cancer cells employ many strategies to evade immune defense and to facilitate tumor growth and angiogenesis. As a novel mode of intercellular communication, cancer-derived exosomes contribute to the recruitment and mediation of lymphocytes within the tumor environment. However, the mechanisms and key molecules mediating the effect of exosomes on lymphocytes are unclear. We treated healthy peripheral blood lymphocytes with exosomes from ovarian cancer and ovarian cysts and screened for differentially expressed genes using the RT(2) Profiler Cancer Inflammation and Immunity Crosstalk PCR Array...

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...

MCs are crucial regulators of the innate immune response. MC degranulation is a rapid response mechanism that allows for the release of a stored plethora of inflammatory mediators, including histamine, heparin, various serine proteases, chemokines, and cytokines. The activation of MCs can lead to the de novo expression of a variety of chemokines and cytokines that can influence a variety of outcomes: inflammation, angiogenesis, and others. A variety of IgE-independent mediators, including IgG, cytokines, chemokines, exogenous molecules, drugs, and cationic peptides, and others, can directly trigger MC activation...

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...

miRNAs are important regulators of cellular senescence yet the extent of their involvement remains to be investigated. We sought to identify miRNAs that are involved in cytokine-induced premature senescence (CIPS) in endothelial cells. CIPS was established in young human pulmonary microvascular endothelial cells (HMVEC-Ls) following treatment with a sublethal dose (20ng/ml) of tumor necrosis factor alpha (TNF-α) for 15days. In parallel, HMVEC-Ls were grown and routinely passaged until the onset of replicative senescence (RS)...

Low-density lipoprotein receptor-related protein-1 (LRP1) plays multifunctional roles in lipid homeostasis, signaling transduction, and endocytosis. It has been recognized as an endocytic receptor for many ligands and is involved in the signaling pathways of many growth factors or cytokines. Dysregulation of LRP1-dependent signaling events contributes to the development of pathophysiologic processes such as Alzheimer's disease, atherosclerosis, inflammation, and coagulation. Interestingly, recent studies have linked LRP1 with endothelial function and angiogenesis, which has been underappreciated for a long time...
