the antioxidant and anti-apoptotic activities of dPrx5 play a critical role in development and aging of the fly
the role of a key metabolic integrator coenzyme A (CoA) in modulating the activity of Prdx5 was investigated.
Studied association of expression levels of peroxiredoxin 5 (PRDX5) and survival in ovarian cancer patients.
Prx V suppresses AGS cell apoptosis via scavenging intracellular ROS and modulating apoptosis-related markers.
human Prx3 rapidly reduces peroxynitrite; Prx3 intrinsic fluorescence presents biphasic changes upon oxidation;Peroxynitrite in excess leads to Prx3 nitration and hyperoxidation;Both Prx3 and Prx5 are predicted to be main targets for mitochondrial peroxynitrite.
Prx V regulates colon cancer cell apoptosis via scavenging ROS cellular levels and mediating the Wnt/beta-catenin signaling pathway, which was induced by beta-lapachone.
These results suggest that there are distinct prognostic values of PRDX family members in patients with ovarian cancer, and that the expression of PRDX3, PRDX5, and PRDX6 mRNAs are a useful prognostic indicator in the effect of chemotherapy in ovarian cancer patients.
Single-molecule experiments demonstrate that PRDX5 specifically binds to TLR4. PRDX5 binding induces a cellular mechanoresponse.
High PRX5 expression is associated with gastric cancer.
Results found that Prx5 was increased in the cellular model of Alzheimer's disease (AD) and, identify a role for Prx5 as an upregulator of Cdk5 activation via reactive oxygen species-mediated Ca2+-mediated calpain activation.
The PRX5 can be used as a predictive biomarker and serves as a putative therapeutic target for the development of clinical treatments for human CRC.
peroxisomal PRDX5 protects oligodendrocytes against peroxisomal and mitochondrial oxidative stress.
show here how the ligand-observed saturation transfer difference (STD) experiment and the PRDX5 protein-observed 15N-HSQC experiment, two popular NMR screening experiments, can be used to compare the binding modes of analogous fragments
PRX5 is either consumed or its production is impaired in severe stroke
This study demonistrated that overexpression of mitochondrial PRDX5 protects SH-SY5Y cells against the ROS/RNS-dependent neuronal death induced by MPP+.
The promoter region critical for Prx5 gene regulation to which the novel negative transcription regulator, GATA1 binds in human breast cancer cell lines.
basal expression of the human PRDX5 gene is regulated by GABP
analysis of fragment molecules that bind the human peroxiredoxin 5 active site
Glutaredoxin-dependent peroxiredoxin from poplar: protein-protein interaction and catalytic mechanism
the expression of peroxiredoxin 5 is upregulated in osteoarthritis
multiple subcellular targeting of peroxiredoxin 5 in mammalian cells can be implicated in antioxidant protective mechanisms under nonpathological conditions
Authors demonstrate that engaging the antioxidant response is sufficient to suppress Toll-like receptor (TLR)-induced cytokine production in dendritic cells and that Prdx5 is required for attenuation of inflammatory cytokine production.
Deletion of Prdx5 increases susceptibility to high-fat diet-induced obesity.
glutamate-stimulated activation of ROS may provoke the induction of Prx V, which has an antioxidative function in glutamate-stimulated HT22 cell apoptosis, and PrxV may serve a role in neural apoptosis.
PRX1 and PRX5 were upregulated in osteoblasts in the proximal tibial metaphysis of ovariectomized mice. Interestingly, PRX1 and PRX5 showed different distribution patterns, with PRX1 mainly accumulated in cell nuclei and PRX5 in the cytoplasm.
These data provided a plausible mechanism linking maternal vitamin D deficiency with altered postnatal lung function.
The ventral signal observed from E12.5 on colocalized with motor neuron markers Isl1/2 and FoxP1 and The strong ventral signal colocalizing wtth Isl1/2 was observed in all rostrocaudal segments of the spinal cord.
results suggest that PrdxV is a key mediator contributing to the regulation of LPS/TLR4-induced immune responses
IMS-PRDX5 expression also attenuates the increase in cytosolic [Ca(2+)] in PASMCs during hypoxia.
The SirT1 regulates the expression of several antioxidant genes in bovine aortic endothelial cells, including Mn superoxide dismutase, catalase, peroxiredoxins 3 and 5, thioredoxin 2, thioredoxin reductase 2, and uncoupling protein 2.
Prx V plays a key role in the microglial activation process through modulation of the balance between ROS/NO generation and the corresponding JNK cascade activation.
PRDX5 has a role in neuroprotection
Prx5 levels also appear to be highly dependent on c-Myc, and chromatin immunoprecipitation experiments showed differential occupancy of c-Myc and Prx1 complexes at E-box elements in the prx5 gene proximal promoter
These results suggest that the antioxidant and antiapoptotic activities of PRDX5 play important roles in the in vitro development of bovine SCNT embryos.
Bovine cauda sperm PRDX5 acts as an antioxidant enzyme in the epididymal environment.
This gene encodes a member of the peroxiredoxin family of antioxidant enzymes, which reduce hydrogen peroxide and alkyl hydroperoxides. The encoded protein may play an antioxidant protective role in different tissues under normal conditions and during inflammatory processes. This protein interacts with peroxisome receptor 1. The crystal structure of this protein in its reduced form has been resolved to 1.5 angstrom resolution. This gene uses alternate in-frame translation initiation sites to generate mitochondrial or peroxisomal/cytoplasmic forms. Three transcript variants encoding distinct isoforms have been identified for this gene.
