Pagină 1 din 16 rezultate
Mutants at the hprt locus isolated after treatment of cells of the human lymphoblastoid cell line TK6 with X rays were examined by Northern blot and cDNA sequence analysis. In previous work, Southern blot analysis showed that approximately 25% of the mutants isolated from cultures treated with X

The effect of the radiosensitizer misonidazole (Ro-07-0582) on the formation of thymine base damage of the 5,6-dihydroxydihydrothymine-type by gamma rays was measured under aerobic and hypoxic conditions. HeLa cells, prelabeled with [methyl-3H]thymidine, were suspended in phosphate-buffered saline

The majority of the adaptation processes to hypoxia is based on transcriptional regulation by hypoxia-inducible factors--HIFs. Recently the allele polymorphism of oxygen-dependent degradation domain of HIF-lalpha has been described. It consists in the replacement of cytosine for thymine in 1772

An erythropoietin gene polymorphism in the hypoxia-responsive element at position 3434 is possibly associated with hypertension.

OBJECTIVE Several polymorphisms of vasoactive hormones have been implicated in hypertension. Erythropoietin (EPO) interacts with vasoactive substances, such as angiotensin II. Previously detected single nucleotide polymorphisms in the hypoxia-responsive element of EPO might be associated with

Photodynamic therapy is a promising approach to treat a variety of superficial tumors and other diseases. One of its major limitations arises from its dependence on molecular oxygen, which decreases the efficiency of the therapy in hypoxia conditions commonly developed by solid tumors. The present

Prevention of hypoxia-induced apoptosis by the angiogenic factor thymidine phosphorylase.

The angiogenic factor platelet-derived endothelial cell growth factor/thymidine phosphorylase (PD-ECGF/TP) is expressed at higher levels in a wide variety of solid tumors compared to adjacent normal tissues. Patients with PD-ECGF/TP-positive colon and esophageal tumors have a poorer prognosis than

Radiopharmaceuticals in preclinical and clinical development for monitoring of therapy with PET.

This review article discusses PET agents, other than (18)F-FDG, with the potential to monitor the response to therapy before, during, or after therapeutic intervention. This review deals primarily with non-(18)F-FDG PET tracers that are in the final stages of preclinical development or in the early

Thymidine phosphorylase (TP), an enzyme involved in the reversible conversion of thymidine to thymine, is identical to an angiogenic factor, platelet-derived endothelial cell growth factor (PD-ECGF). Both TP and one of the TP-degradation products of thymidine 2-deoxy-D-ribose (dRib) display

2-Deoxy-D-ribose, a downstream mediator of thymidine phosphorylase, regulates tumor angiogenesis and progression.

Angiogenesis plays an important role in tumor metastasis and progression, and thus inhibiting angiogenesis is a promising strategy for treatment of cancer. However, tumor-associated angiogenesis is influenced by various angiogenic factors in the tumor microenvironment. Thymidine phosphorylase (TP,

OBJECTIVE Human umbilical cord mesenchymal stem cells (hUCMSCs) have renoprotective effects but the influence of the microenvironment on characteristics of hUCMSCs has not been well studied. Here, we investigate the effects of injury conditions on properties of hUCMSCs. RESULTS hUCMSCs were treated
An HPLC method was used to determine whether postmortem time and storage temperature affect the concentrations of purines, pyrimidines, and nucleosides in avian and porcine vitreous humor. Inosine, hypoxanthine, xanthine, uric acid, uracil, uridine, and thymine were identified in the vitreous humor
Ionizing radiation triggers the activation of caged oligodeoxynucleotides (ODNs) with a 2-oxoalkyl leaving group to give the corresponding normal uncaged strands. We designed and synthesized ODNs caged by a 2-oxopropyl group at a given thymine N(3) position (d(oxo)T) to evaluate their one-electron

Congenital myotonic dystrophy (CDM1) is an autosomal dominant genetic disorder caused by abnormal cytosine-thymine-guanine trinucleotide repeat expansion that results in weakness and cognitive deficits. Studies detailing brain magnetic resonance imaging (MRI) findings in neonates and

We have measured the yield of single-strand breaks (SSBs) in plasmid DNA after 137Cs gamma irradiation, in the presence of dimethyl sulfoxide (DMSO). In the presence of oxygen, the formation of SSBs is due to hydroxyl radical attack. As the DMSO concentration is increased from 10(-4) mol dm-3 to 1

Thymidine phosphorylase (TP) is a nucleoside metabolism enzyme that plays an important role in the pyrimidine pathway.TP catalyzes the conversion of thymidine to thymine and 2-deoxy-α-D-ribose-1-phosphate (dRib-1-P). Although this reaction is reversible, the main metabolic function of TP is
