Ape1 regulates hematopoietic differentiation of embryonic stem cells through its redox functional domain
APE1 DNA repair hematopoiesis
2014/12/12
Ape1 is a molecule with dual functions in DNA repair and redox regulation of transcription factors. In Ape1-deficient mice, embryos do not survive beyond embryonic day 9, indicating that this molecule...
Lack of EGF receptor contributes to drug sensitivity of human germline cells
DNA damage epidermal growth factor receptor drug resistance
2014/12/12
Germline mutations have been associated with generation of various types of tumour. In this study, we investigated genetic alteration of germline tumours that affect the drug sensitivity of cells. Alt...
Protection of pulmonary epithelial cells from oxidative stress by hMYH adenine glycosylase
oxygen toxicity hMYH adenine glycosylase
2014/12/12
Background: Oxygen toxicity is a major cause of lung injury. The base excision repair pathway is one of the most important cellular protection mechanisms that responds to oxidative DNA damage. Lesion-...
Role of the Multifunctional DNA Repair and Redox Signaling Protein Ape1/Ref-1 in Cancer and Endothelial Cells: Small-Molecule Inhibition of the Redox Function of Ape1
APE1/Ref-1 redox signaling cancer
2014/12/12
The DNA base excision-repair pathway is responsible for the repair of DNA damage caused by oxidation/alkylation and protects cells against the effects of endogenous and exogenous agents. Removal of th...
Role of Ape1 and Base Excision Repair in the Radiation Response and Heat-radiosensitization of HeLa Cells
radiation hyperthermia DNA repair
2014/12/12
Background: The mechanism by which heat sensitizes mammalian cells to ionizing radiation remains to be elucidated. We determined whether base excision repair (BER) is involved in heat-radiosensitizati...
Protection of Human Lung Cells against Hyperoxia Using the DNA Base Excision Repair Genes hOgg1 and Fpg
oxygen toxicity DNA damage DNA repair
2014/12/12
Hyperoxia causes pulmonary toxicity in part by injuring alveolar epithelial cells. Previous studies have shown that toxic oxygen-derived species damage DNA and this damage is recognized and repaired b...
Role of APE1 in differentiated neuroblastoma SH-SY5Y cells in response to oxidative stress; Use of APE1 small molecule inhibitors to delineate APE1 functions
base excision repair APE1/Ref-1 oxidative stress
2014/12/12
Oxidative DNA damage has been implicated in a number of central nervous system pathologies. The base excision repair (BER) pathway is one of the most important cellular protection mechanisms that resp...
Genome-wide analysis and proteomic studies reveal APE1/Ref-1 multifunctional role in mammalian cells
APE1/Ref-1 cell signaling difference analysis
2014/12/12
Apurinic apyrimidinic endonuclease/redox effector factor 1 (APE1/Ref-1) protects cells from oxidative stress by acting as a central enzyme in base excision repair pathways of DNA lesions and through i...
A novel fluorometric oligonucleotide assay to measure O 6-methylguanine DNA methyltransferase, methylpurine DNA glycosylase, 8-oxoguanine DNA glycosylase and abasic endonuclease activities: DNA repair status in human breast carcinoma cells overexpressing methylpurine DNA glycosylase
APE1/Ref-1 DNA repair status
2014/12/12
DNA repair status plays a major role in mutagenesis, carcinogenesis and resistance to genotoxic agents. Because DNA repair processes involve multiple enzymatic steps, understanding cellular DNA repair...
Rac Activation Induces NADPH Oxidase Activity in Transgenic COSphox Cells and Level of Superoxide Production is Exchange Factor-Dependent
NADPH oxidase Rac
2014/12/12
Transient expression of constitutively active Rac1 derivatives, (G12V) or (Q61L), was sufficient to induce phagocyte NADPH oxidase activity in a COS-7 cell model in which human cDNAs for essential oxi...
Neurofibromin-deficient Schwann cells secrete a potent migratory stimulus for Nf1+/– mast cells
neurofibromin Schwann cells mast cells
2014/12/12
The NF1 tumor suppressor gene encodes a GTPase-activating protein called neurofibromin that negatively regulates Ras signaling. Mutations in NF1 cause neurofibromatosis type 1 (NF1). The development o...
Induction of IgE synthesis by genetically modified CD8+ T cells of a patient with adenosine deaminase deficiency
CD40 ligand CD8+ T cells gene therapy IgE production interleukin-4
2010/11/26
We have previously reported that an adenosine deaminase (ADA)-deficient patient treated with T cell-directed gene therapy had an increase in serum IgE levels, despite a marked inversion of the CD4/CD8...
