Recent evidence suggests that histone deacetylase inhibitors (HDACi) may mediate part of their antitumor effects by interfering with tumor angiogenesis. As signalling via the vascular endothelial growth factor receptor-2 (VEGFR-2) pathway is critical for angiogenic responses during progression, we explored whether established HDACi are partly mediated through diminished VEGFR-2 expression. We therefore examined potential impact three different HDACi, trichostatin A (TSA), sodium butyrate...

The formation of new lymphatic vessels provides an additional route for tumour cells to metastasize. Therefore, inhibiting lymphangiogenesis represents interesting target in cancer therapy. First evidence suggests that histone deacetylase inhibitors (HDACi) may mediate part their antitumor effects by interfering with lymphangiogenesis. However, the underlying mechanisms HDACi induced anti-lymphangiogenic properties are not fully investigated so far and remain unknown.Human endothelial (LEC)...

Patients with chronic inflammatory diseases (e.g. psoriasis and rheumatoid arthritis) are at increased risk for the development of atherosclerosis cardiovascular (CVD). Previous studies have suggested that phosphodiesterase 4 (PDE4) inhibitors possess anti-inflammatory properties.Here we examined effect PDE4 inhibitor apremilast, a well-established anti-psoriatic drug, on pro-inflammatory responses in TNFα-activated endothelial cells.Human umbilical vein cells (HUVEC) were treated tumour...

Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that implicated in the regulation of lipid and glucose homeostasis. PPAR agonists have been shown to control inflammatory processes, part by inhibiting distinct proinflammatory genes (e.g. Il-1β IFN-γ). IL-8 is a member chemokine family important for various functions, such as mediating adhesion eosinophilic granulocytes onto endothelial cells. The influence PPARδ activators on expression...

Inflammation, angiogenesis and oxidative stress have been implicated in the pathogenesis of various vascular diseases. Recent evidence suggests that dimethylfumarate (DMF), an antiposriatic anti-multiple sclerosis agent, possesses anti-inflammatory, anti-oxidative anti-angiogenic properties. Here, we analyze influence DMF on TNF-α-induced expression important pro-inflammatory pro-atherogenic chemokine MCP-1 investigate underlying mechanisms this expression.We analyzed constitutive human...

The ubiquitin-proteasome system is the major pathway for intracellular protein degradation in eukaryotic cells. This controls a wide range of cellular regulatory proteins, including transcription factors and cell cycle proteins. Recent evidence also established importance proteasome tumor development, showing antitumor antiangiogenic actions by using selective inhibitors vivo. As signaling via vascular endothelial growth factor receptor 2 (VEGFR2) critical angiogenic responses to occur, we...

Recent evidence suggests that dimethylfumarate (DMF), known as a highly potent anti-psoriatic agent, might have anti-tumorigenic properties in melanoma. It has recently been demonstrated DMF inhibits melanoma proliferation by apoptosis and cell cycle inhibition therefore metastasis. Nonetheless, the underlying mechanisms remain to be evaluated. To elucidate effects of on lines (A375, SK-Mel), we first performed cytotoxicity assays. No significant lactatedehydogenase (LDH) release could...

Abstract Impaired wound healing as well imbalanced cell proliferation and extracellular matrix synthesis degeneration can cause aberrant scarring. The most severe impacts of such scarring on patients' lives are stigmatization physical restriction. Although, a broad variety combinatorial approaches with, e.g., glucocorticoids, chemotherapeutics, immunomodulators used, there is still high recurrence rate keloids. aim this study was to investigate which influence interferon γ (IFN‐γ,...

Mantle cell lymphoma (MCL) is a unique type of B-cell non-Hodgkin's lymphoma, which very rarely exhibits skin involvement. We herein describe the case 55-year-old woman, who initially presented with nodular mass right infraorbital region. On histological analysis subcutaneous tissue, diffuse neoplastic infiltration was identified, composed medium‑sized lymphoid cells irregular nuclei, diagnosed as MCL. The tumor were positive for CD5, CD20, CD79a, cyclin D1 and sex‑determining region Y-box...

Abstract: Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that function mainly in the regulation of glucose and lipid homeostasis. PPAR agonists have been shown to control inflammation by inhibition distinct proinflammatory genes. Aberrant activation epidermal growth factor receptor and/or overexpression its ligand, transforming factor-α (TGFα), key features both neoplastic inflammatory hyperproliferative epithelia. Matrix metalloproteinase 9...

Different pathologies, such as lymphoedema, cancer or psoriasis, are associated with abnormal lymphatic vessel formation. Therefore, influencing lymphangiogenesis is an interesting target. Recent evidence suggests that dimethylfumarate (DMF), antipsoriatic agent, might have antitumorigenic and antilymphangiogenic properties. To prove this assumption, we performed proliferation functional assays primary human dermal lymphendothelial cells (DLEC). We could demonstrated DMF suppresses DLEC...

Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that implicated in the regulation of lipid and glucose homeostasis. PPAR agonists have been shown to control inflammatory processes, part by inhibiting expression distinct proinflammatory genes such as vascular cell adhesion molecule-1 (VCAM-1), IL-8, intercellular (ICAM-1). ICAM-1 is an important endothelial membrane receptor facilitates transmigration leukocytes across endothelium. To date,...

Abstract: RhoA, Rac1 and CDC42 are small GTP‐binding proteins of the Rho family that play a crucial role in regulation actin‐based cytoskeleton. In addition to cell growth regulation, they implicated transcriptional activation, oncogenic transformation angiogenesis. The Rho‐GTPases have been linked vascular endothelial factor (VEGF)‐induced signalling pathways, but their has not yet elucidated. As via VEGF receptor‐2 (VEGFR2) pathway is critical for angiogenic responses cancer, wound repair...

Abnormalities in the expression of human leucocyte antigens (HLA) by tumour cells impair cellular immune responses promoting evasion and survival. To date, studies analysing HLA class I II levels malignant fibrous histiocytomas, fibrosarcomas dermatofibrosarcoma protuberans are limited.Therefore, we investigated vivo profile 99 20 34 from different anatomical sites.Immunohistochemistry using monoclonal antibodies to was used define these on respective samples.Frequent loss or downregulation...

Measurements of extracellular pH show that the micro environment malignant tumors is more acidic than normal cells, whereas does not differ appreciable in and cells. The acid created by secretion tumor factors ATP hydrolysis hypoxic tissue. In order to survive a low pH-environment cells develop regulatory mechanisms which keep their intracellular stable. Two most important systems are Na+/H+ ion pump Na-dependent HCO3-/Cl- stilbenian derivatives.Experiments were carried out on DBA mice both...

Abstract Peroxisome proliferator‐activated receptor ( PPAR ) delta agonists are known to have distinct anti‐inflammatory and antitumor effects; though, the knowledge regarding their mode of action has thus far been limited. Different cathepsins shown be upregulated in a broad range pathological events, such as rheumatoid arthritis, psoriasis, atherosclerosis diverse tumor entities, for example melanoma. Recent work demonstrated that cathepsin B particular is an important pro‐angiogenic...
