OBJECTIVE The aim of the present study was to investigate regulatory mechanisms of angiogenesis in the decidua using immortalized human decidual fibroblasts. METHODS A sample of decidual fibroblasts was taken from a woman in early pregnancy. A cell line, DE-1, was established by infecting the

Purpose: Acute retinal necrosis (ARN) is caused by varicella zoster virus (VZV) infection. In this study, we investigated the activity of this virus and expressions of some cytokines.Patients and Methods: The expressionof VZV thymidine kinase and some cytokines were investigated by reverse

OBJECTIVE Acute retinal necrosis (ARN) is caused by varicella zoster virus (VZV) infection. In this study, we investigated the activity of this virus and expressions of some cytokines. METHODS The expression of VZV thymidine kinase and some cytokines were investigated by reverse

The effect of human tumor necrosis factor (TNF) on early-passage HL-60 cells was studied. A transient phase of increased [3H]thymidine (TdR) incorporation was noted at 20-24 hr of exposure to TNF. This increase was disproportionate to the much slighter stimulation of the percentage of S-phase cells,

We have assessed the effect of combine cancer gene therapy with exogenous human tumor necrosis factor alpha (hTNFalpha) and suicide gene therapy on three human cancer cell lines MCF-7 (breast adenocarcinoma), U-118MGand 42-MG-BA (human gliomas). Transfection of a plasmid containing hTNFalpha under

The angiogenic factor thymidine phosphorylase (TP) is highly expressed in human monocytes and macrophages, and its expression has been linked to the pathology and progression of solid tumors, rheumatoid arthritis, and gastric ulcers. In this study, TP mRNA and enzyme activity were found to be

Past studies have documented the promise of herpes simplex virus type 1 (HSV-1) thymidine kinase (TK) suicide gene therapy as a potential antitumor treatment. HSV-TK converts the pro-drug ganciclovir (GCV) into a toxic nucleotide analogue, the incorporation of which into cellular DNA blocks cell

The goal of this work was to identify potential host immune responses to thymidine kinase (TK) suicide gene-modified tumors undergoing chemoablation induced by the prodrug ganciclovir (GCV). The aims were to measure the efficacy and specificity of immunity induced against unmodified tumor, to

Angiogenesis is an essential requirement for tumour growth and metastasis and is regulated by a complex network of factors produced by both stromal cells and neoplastic cells within solid tumours. The cytokine tumour necrosis factor alpha (TNF-alpha) and the enzyme thymidine phosphorylase (TP) are

Thymidine phosphorylase (TP; also known as platelet-derived endothelial cell growth factor, PD-ECGF) is an angiogenic factor that is chemotactic for endothelial cells and has been found to induce neovascularization in vivo. TP is frequently overexpressed in human solid tumors, where its expression

Gliostatin/thymidine phosphorylase (GLS/TP) is known to have angiogenic and arthritogenic activities. The purpose of this study was to determine the inhibitory effects of FK506 (tacrolimus) on GLS production in rheumatoid arthritis (RA). We investigated the modulation of serum GLS by FK506 therapy

Human uveal melanoma is the most common primary intraocular tumor, and brachytherapy is one of the most common and effective treatment strategies. In order to find a safer and more effective way to increase the radio sensitivity of the tumor, we tried to use the dendrimer nanoparticle performing

After massive liver injury with acetaminophen, subcoma doses of hepatic failure toxins (NH+4, dimethyl disulfide [----methanethiol], octanoic acid) depressed liver thymidine kinase (TK) activity by 78%, 85%, and 90%, respectively, and ornithine decarboxylase (ODC) activity by 40%, 83%, and 78%,

BACKGROUND Anti-tumor necrosis factor (TNF)-α biotherapies have considerably changed the treatment of rheumatoid arthritis (RA). However, serious infections are a major concern in patients with rheumatic diseases treated with anti-TNF-α. Little is known about viral, especially latent, infections in
