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...
DNA Repair Proteins as Molecular Targets for Cancer Therapeutics
DNA repair cancer therapeutics
2014/12/12
Cancer therapeutics include an ever-increasing array of tools at the disposal of clinicians in their treatment of this disease. However, cancer is a tough opponent in this battle and current treatment...
Conversion of the Bifunctional 8-oxoguanine/β-δ AP DNA Repair Activities of Drosophila Ribosomal Protein S3 into the Human S3 Monofunctional β- elimination Catalyst Through a Single Amino Acid Change
DNA repair drosophila ribosomal protein s3
2014/12/12
The Drosophila S3 ribosomal protein has important roles in both protein translation and DNA repair. In regards to the latter activity, it has been shown that S3 contains vigorous N-glycosylase activit...
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...
Conditional Targeting of the DNA Repair Enzyme hOGG1 into Mitochondria
DNA repair mitochondria
2014/12/12
Oxidative damage to mitochondrial DNA (mtDNA) has been suggested to be a key factor in the etiologies of many diseases and in the normal process of aging. Although the presence of a repair system to r...
Knockdown of the DNA repair and redox signaling protein Ape1/ Ref-1 blocks ovarian cancer cell and tumor growth
base excision repair APE1/Ref-1 ovarian cancer
2014/12/12
Apurinic endonuclease 1/redox effector factor-1 (Ape1/Ref-1 or Ape1) is an essential protein with two distinct functions. It is a DNA repair enzyme in the base excision repair (BER) pathway and a redu...
APE1/Ref-1 (APE1), the mammalian ortholog of Escherichia coli Xth, and a multifunctional protein possessing both DNA repair and transcriptional regulatory activities, has a pleiotropic role in control...
