1. Arc extracellular vesicles mediate intercellular transfer of Arc mRNA in neurons.

2. Specific acetylation of lysine residues on Arc promote Arc protein stability.

3. Stress from escapable electroshock (ES) was associated with up-regulation of brain-derived neurotrophic factor in amygdala as well as medial prefrontal cortex (mPFC). Stres from inescapable shock suppressed c-fos in mPFC (0 h) but induced more Arc in amygdala (2 h) in comparison with ES.

4. Our data support the hypothesis that the kinetics of Arc induction to refine cortical representations of sensory categories is sensitive to the familiarity of the sensory experience.

5. PSD95 was essential for Arc assembly into 1.5-MDa complexes and activity-dependent recruitment to excitatory synapses.

6. Data show that although activity-dependent expression of activity regulated cytoskeletal-associated protein (Arc) mRNA does not change with age, expression of Arc protein is maximal during the critical period and declines in adulthood.

7. It appears that palmitoylation regulates at least a subset of Arc functions in synaptic plasticity.

8. These results indicate that dopamine is required to drive activity-dependent amplification of Arc mRNA in the developing postnatal frontal cortex.

9. Study demonstrates in mice that explored novel spatial environments, the involvement of Egr3 in regulating the late protein-dependent phase of Arc expression in the dentate gyrus.

10. Arc/Arg3.1 effects on memory formation are not only manifested at the level of molecular pathways regulating synaptic plasticity, but also at the systems level.

11. CTCF knockdown attenuates fear-conditioning-induced hippocampal gene expression of key learning genes and loss of long-range interactions at the BDNF and Arc loci.

12. Genetic disruption of Arc in mice causes alterations in dopamine and neurobehavioral phenotypes related to schizophrenia.

13. Data indicate that ARC overexpression diminishes amyloid-induced JNK pathway activation and apoptosis in the beta-cell, a strategy that may reduce beta-cell loss in type 2 diabetes

14. Activity-regulated cytoskeleton-associated protein accumulates in the nucleus in response to cocaine and acts as a brake on chromatin remodeling and long-term behavioral alterations.

15. This is a promising novel therapeutic approach because it appears to be effective in a model producing severe injury by interfering with an array of proximal signals and effectors of the ischemic cascade, upstream of JNK, caspases, and BIM and BAX activation.

16. missense mutations in TRIAD3 abolished the interaction of TRIAD3A with Arc, disrupting Arc ubiquitination, and consequently Arc degradation.

17. The dynamics of the c-Fos and Arc expression has a biphasic pattern: the first peak was observed in 15-30 min after learning and the second less pronounced peak in 1-3 h.

18. we report that late Arc expression is essential for the persistence of newly-acquired and reactivated memories. Persistent fear memories could be a factor in post-traumatic stress disorder.

19. Arc-expressing neurons have enhanced intrinsic excitability and are preferentially recruited into newly encoded memory traces.

20. These findings suggest that 11beta-HSD1 may contribute to the decline in Npas4 and Arc mRNA levels associated with memory impairment during ageing

Human Activity-Regulated Cytoskeleton-Associated Protein (Arc) interaction partners

1. Our results indicated that the Arc gene would confer susceptibility to Alzheimer disease in Han Chinese, probably through changing the protein structure or affecting the Arc expression in brain tissues, which would finally contribute to the pathogenesis and development of AD.

2. The ARC complex revealed association with verbal and total IQ in child.

3. Study identified several rare mutations that reduced ARC expression in schizophrenia patients. Furthermore, DNA methylation of ARC in schizophrenia patients may be associated with a downregulation of ARC mRNA expression. These findings suggest that multiple rare ARC variants and DNA methylation of ARC might contribute to the pathogenesis of schizophrenia.

4. missense mutations in TRIAD3 abolished the interaction of TRIAD3A with Arc, disrupting Arc ubiquitination, and consequently Arc degradation.

5. ARC confers resistance to sunitinib in renal cell carcinoma through alternate angiogenesis pathways

6. We tested whether ARC variants are associated with six measures of cognitive functioning in 670 healthy subjects in the Norwegian Cognitive NeuroGenetics (NCNG) by extracting data from its Genome-Wide Association Study (GWAS).

7. this is the first report associating an ARC SNP with schizophrenia and supports recent large-scale GWAS findings implicating the ARC complex in schizophrenia risk

8. we propose that the peculiar characteristics of Arc protein, such as its optimal expression after ongoing experience or familiar behavior could explain how familiarization and recognition memories are stored and preserved in the mammalian brain--{REVIEW}

9. mRNA levels of ARC and SGK1 did not differ significantly between the schizophrenia or control samples.

10. Arc is a flexible multi-domain protein that exists in monomeric and oligomeric forms, compatible with a diverse, hub-like role in plasticity-related processes.

11. Degradation of Arc by clathrin-localized Triad3A regulates the availability of synaptic AMPA receptors.

12. we report a novel ARC single nucleotide polymorphism associated with a reduced risk of developing Alzheimer disease.

13. analysis of dynamic, multifaceted control of Arc synthesis during mAchR signaling

14. Strong fibrinogen and Abeta deposition is demonstrated in small- and medium-sized vessels, but not in large cerebral arteries, of 24-month-old transgenic arcAbeta mice.

15. Arc Expression Is Increased in medial frontal cortex of patients with Alzheimer's Disease.

16. Arc/MS2 mRNA assembles into particles that move independently, bidirectionally, and intermittently. These observations identify several phases of Arc mRNA movement that serve as potential points for regulating Arc mRNA localization.
