Resveratrol ameliorates prenatal progestin exposure-induced autism-like behavior through ERbeta activation / W. XIE in Molecular Autism, 9 (2018)

Titre : Resveratrol ameliorates prenatal progestin exposure-induced autism-like behavior through ERbeta activation Type de document : Texte imprimé et/ou numérique Auteurs : W. XIE, Auteur ; X. GE, Auteur ; L. LI, Auteur ; A. YAO, Auteur ; X. WANG, Auteur ; M. LI, Auteur ; X. GONG, Auteur ; Z. CHU, Auteur ; Z. LU, Auteur ; X. HUANG, Auteur ; Y. JIAO, Auteur ; Y. WANG, Auteur ; M. XIAO, Auteur ; H. CHEN, Auteur ; W. XIANG, Auteur ; P. YAO, Auteur Article en page(s) : 43p. Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Estrogen receptor beta Lipid metabolism Mitochondria Oxidative stress Progestin Resveratrol Index. décimale : PER Périodiques Résumé : Background: Recent literatures indicate that maternal hormone exposure is a risk factor for autism spectrum disorder (ASD). We hypothesize that prenatal progestin exposure may counteract the neuroprotective effect of estrogen and contribute to ASD development, and we aim to develop a method to ameliorate prenatal progestin exposure-induced autism-like behavior. Methods: Experiment 1: Prenatal progestin exposure-induced offspring are treated with resveratrol (RSV) through either prenatal or postnatal exposure and then used for autism-like behavior testing and other biomedical analyses. Experiment 2: Prenatal norethindrone (NET) exposure-induced offspring are treated with ERbeta knockdown lentivirus together with RSV for further testing. Experiment 3: Pregnant dams are treated with prenatal NET exposure together with RSV, and the offspring are used for further testing. Results: Eight kinds of clinically relevant progestins were used for prenatal exposure in pregnant dams, and the offspring showed decreased ERbeta expression in the amygdala with autism-like behavior. Oral administration of either postnatal or prenatal RSV treatment significantly reversed this effect with ERbeta activation and ameliorated autism-like behavior. Further investigation showed that RSV activates ERbeta and its target genes by demethylation of DNA and histone on the ERbeta promoter, and then minimizes progestin-induced oxidative stress as well as the dysfunction of mitochondria and lipid metabolism in the brain, subsequently ameliorating autism-like behavior. Conclusions: We conclude that resveratrol ameliorates prenatal progestin exposure-induced autism-like behavior through ERbeta activation. Our data suggest that prenatal progestin exposure is a strong risk factor for autism-like behavior. Many potential clinical progestin applications, including oral contraceptive pills, preterm birth drugs, and progestin-contaminated drinking water or seafood, may be risk factors for ASD. In addition, RSV may be a good candidate for clinically rescuing or preventing ASD symptoms in humans, while high doses of resveratrol used in the animals may be a potential limitation for human application.

Titre : Social synchronization during joint attention in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Q. LIU, Auteur ; Q. WANG, Auteur ; X. LI, Auteur ; X. GONG, Auteur ; X. LUO, Auteur ; T. YIN, Auteur ; J. LIU, Auteur ; L. YI, Auteur Article en page(s) : p.2120-2130 Langues : Anglais (eng) Mots-clés : Attention Autism Spectrum Disorder Child Cues Female Fixation, Ocular Humans Social Behavior cross-recurrence quantification analysis eye movement gaze-shift behaviors joint attention social synchronization Index. décimale : PER Périodiques Résumé : We explored the social synchronization of gaze-shift behaviors when responding to joint attention in children with autism spectrum disorder (ASD). Forty-one children aged 5 to 8 with ASD and 43 typically developing (TD) children watched a video to complete the response to joint attention (RJA) tasks, during which their gaze data were collected. The synchronization of gaze-shift behaviors between children and the female model in the video was measured with the cross-recurrence quantification analysis (CRQA). Ultimately, we discovered that children with ASD had the ability to synchronize their gaze shifts with the female model in the video during RJA tasks. Compared to the TD children, they displayed lower levels of synchronization and longer latency in this synchronized behavior. These findings provide a new avenue to deepen our understanding of the impairments of social interaction in children with ASD. Notably, the analytic method can be further applied to explore the social synchronization of numerous other social interactive behaviors in ASD. LAY SUMMARY: This study explored how autistic children synchronized their gazed shifts with others' gaze cues during joint attention. We found that compared to typical children, autistic children synchronized their gazed shifts less and needed more time to follow others' gaze. These findings provide a new avenue to deepen our understanding of the impairments of social interaction in children with ASD.
