Activity-Regulated Cytoskeleton-Associated Protein Dysfunction May Contribute to Memory Disorder and Earlier Detection of Autism Spectrum Disorders
Abstract
OBJECTIVE:
To explore a possible role for activity-regulated cytoskeleton-associated protein (Arc/Arg3.1) in the clinical identification of children with autism.Explorer un rôle possible pour al protéine associée à l'activité régulée du cytosquelette (Arc / Arg3.1) dans l'identification clinique des enfants avec autisme.
SUBJECTS AND METHODS:
The plasma levels of Arc/Arg3.1 in 62 boys with autism and 32 healthy boys were measured using enzyme-linked immunosorbent assay (ELISA). The Childhood Autism Rating Scale (CARS) was used to assess severity of autism as defined in the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, (DSM-IV). Mann-Whitney U tests were used for comparisons between children with autism and healthy children. Spearman's r correlation coefficient (r) was used to determine the relationship between the CARS scores among patients with autism and different variables.RESULTS:
The mean plasma level of Arc/Arg3.1 protein in autism was 1.689 ± 0.917 pg/mL, significantly higher than that of healthy controls: 0.792 ± 1.056 pg/mL (p < 0.001). No significant relationship was found between plasma levels of Arc/Arg3.1 protein and CARS scores (r = - 0.06; p > 0.05), age (r = - 0.27; p > 0.05).La concentration plasmatique moyenne de la protéine Arc / Arg3.1 dans l'autisme était 1,689 ± 0,917 pg / ml, soit nettement supérieure à celle des témoins sans autisme: 0,792 ± 1,056 pg / ml (p <0,001). Aucune relation significative n'a été observée entre les concentrations plasmatiques de la protéine Arc / Arg3.1 et les résultats du CARS (r = - 0,06; p> 0,05), l'âge (r = - 0,27; p> 0,05).
CONCLUSIONS:
The mean plasma level of Arc/Arg3.1 protein was higher in children with autism than in controls, suggesting that Arc/Arg3.1 could be a potential early blood biomarker for diagnosis of autism.Le niveau de la protéine Arc / Arg3.1 plasmatique moyenne était plus élevée chez les enfants autistes que chez les témoins, ce qui suggère que Arc / Arg3.1 pourrait être un biomarqueur sanguin précoce potentiel pour le diagnostic de l'autisme.
