The regulatory role of AP-2β in monoaminergic neurotransmitter systems: insights on its signalling pathway, linked disorders and theragnostic potential. Cell Biosci 2022; 12:151. [PMID: 36076256 PMCID: PMC9461128 DOI: 10.1186/s13578-022-00891-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 08/28/2022] [Indexed: 11/10/2022] Open
Abstract
AbstractMonoaminergic neurotransmitter systems play a central role in neuronal function and behaviour. Dysregulation of these systems gives rise to neuropsychiatric and neurodegenerative disorders with high prevalence and societal burden, collectively termed monoamine neurotransmitter disorders (MNDs). Despite extensive research, the transcriptional regulation of monoaminergic neurotransmitter systems is not fully explored. Interestingly, certain drugs that act on these systems have been shown to modulate central levels of the transcription factor AP-2 beta (AP-2β, gene: TFAP2Β). AP-2β regulates multiple key genes within these systems and thereby its levels correlate with monoamine neurotransmitters measures; yet, its signalling pathways are not well understood. Moreover, although dysregulation of TFAP2Β has been associated with MNDs, the underlying mechanisms for these associations remain elusive. In this context, this review addresses AP-2β, considering its basic structural aspects, regulation and signalling pathways in the controlling of monoaminergic neurotransmitter systems, and possible mechanisms underpinning associated MNDS. It also underscores the significance of AP-2β as a potential diagnostic biomarker and its potential and limitations as a therapeutic target for specific MNDs as well as possible pharmaceutical interventions for targeting it. In essence, this review emphasizes the role of AP-2β as a key regulator of the monoaminergic neurotransmitter systems and its importance for understanding the pathogenesis and improving the management of MNDs.

Abstract
AIM Examination of psychometric properties and diagnostic accuracy of the Depression Self-Rating Scale for Adolescents (DSRS-A) as well as development and evaluations of a shorter version, DSRS-A-Screener. METHODS Analyses of component structure and internal consistency were performed in a community-based sample of adolescents N = 4,506 and among consecutive outpatients from three child psychiatric settings in Sweden (n = 137). Concurrent validity was measured as a correlation between a summation index of the scale items and the total major depressive disorder (MDD) symptom severity score from the Kiddie Schedule of Affective Disorders and Schizophrenia (K-SADS). Diagnostic accuracy was examined in the clinical sample, with the K-SADS interview as the reference test, by receiver operating characteristic analysis (ROC), calculations of sensitivity, specificity among other measures. With the purpose to select items for a shorter scale, associations between scale items and MDD were examined with binary logistic regression. This shorter scale was thereafter examined similarly. RESULTS Based on association with MDD, five items were selected for the brief DSRS-A Screener that showed one component structure, internal consistency Cronbach's alpha .80 and.82, respectively. In the clinical population concurrent validity was Spearman's rho .63 and ROC analysis showed AUC .84 (95% CI .78-.91; p < .001). The optimal cut-off for screening was 2 with sensitivity .85 and specificity of .64. CONCLUSION The DSRS-A Screener compared to the original scale, maintained or improved reliability, validity, and showed moderate diagnostic accuracy.

Abstract
Objective: Modern board and card game-based cognitive interventions and gamification practices showed effectiveness in boosting executive functions and decreasing behavioral problems in children. However, the combination of both game-based methods has not been tested. Therefore, the main aim of this study was to test the effectiveness of gamification in modern board and card game-based cognitive interventions in Spanish schoolchildren at risk of social exclusion. Materials and Methods: In this multicenter single-blind study with a quasi-experimental design, 176 schoolers (6-13 years old) were assigned to a gamified group (with a narrative context and a rewarding system) and 107 to a nongamified group (with no narrative context or rewarding system). The interventions were implemented in regular classes. Behavioral executive dysfunction was assessed using the Behavior Rating Inventory of Executive Function, Second Revision (BRIEF-2) (Teacher form), pre- and postintervention. Results: We found significant time effects in all BRIEF-2 domains with small and medium effect sizes (d = -0.35 to d = -0.62). The nongamified group showed significantly higher decreases in all measures than those who used gamification. Conclusions: It is possible that playing for the joy of playing in the nongamified group was enough motivation to focus on the task, while adding gamification elements did not favor greater effectiveness of the program.

Abstract
In pregnant women with epilepsy, it is imperative to balance the safety of the mother and the potential teratogenicity of anticonvulsants, which could cause impairments such as intellectual disability and cleft lip. In this study, we examined behavioral and hippocampal neurogenesis alterations in male offspring of rats exposed to valproic acid (VPA) during pregnancy. Pregnant Wistar rats received daily intraperitoneal injections of VPA (100 mg/kg/day or 200 mg/kg/day) from embryonic day 12.5 until birth. At postnatal day 29, animals received an injection of bromodeoxyuridine (BrdU). At postnatal day 30, animals underwent the open field (OF), elevated plus-maze, and Y-maze tests. After behavioral testing, animals were decapitated, and their brains were dissected for immunohistochemistry. Of the offspring of the VPA200 mothers, 66.6% showed a malformation. In the OF test, these animals showed locomotor hyperactivity. In the elevated plus-maze, offspring of VPA-treated mothers spent significantly more time in the open arms, irrespective of the treatment dose. The number of BrdU-positive cells in the dentate gyrus of the offspring of VPA-treated mothers increased significantly in a dose-dependent manner compared with the control. A significant positive correlation between spontaneous locomotor activity in the OF and BrdU-positive cell counts was observed across groups. In conclusion, VPA administration during pregnancy results in malformations and attention-deficit/hyperactivity disorder-like behavioral abnormalities in the offspring. An increase in cell proliferation in the hippocampus may underlie the behavioral changes observed. Repeated use of high doses of VPA during pregnancy may increase the risk of neurodevelopmental abnormalities dose dependently and should be carefully considered.

Abstract
How the human brain differs from those of non-human primates is largely unknown and the complex drivers underlying such differences at the genomic level remain unclear. In this study, we selected 243 brain-related genes, based on Gene Ontology, and identified 184,113 DNaseI hypersensitive sites (DHSs) within their regulatory regions. To performed comprehensive evolutionary analyses, we set strict filtering criteria for alignment quality and filtered 39,132 DHSs for inclusion in the investigation and found that 2,397 (~6%) exhibited evidence of accelerated evolution (aceDHSs), which was a much higher proportion that DHSs genome-wide. Target genes predicted to be regulated by brain-aceDHSs were functionally enriched for brain development and exhibited differential expression between human and chimpanzee. Alignments indicated 61 potential human-specific transcription factor binding sites in brain-aceDHSs, including for CTCF, FOXH1, and FOXQ1. Furthermore, based on GWAS, Hi-C, and eQTL data, 16 GWAS SNPs, and 82 eQTL SNPs were in brain-aceDHSs that regulate genes related to brain development or disease. Among these brain-aceDHSs, we confirmed that one enhanced the expression of GPR133, using CRISPR-Cas9 and western blotting. The GPR133 gene is associated with glioblastoma, indicating that SNPs within DHSs could be related to brain disorders. These findings suggest that brain-related gene regulatory regions are under adaptive evolution and contribute to the differential expression profiles among primates, providing new insights into the genetic basis of brain phenotypes or disorders between humans and other primates.

Abstract
Childhood maltreatment is a significant risk factor for a host of psychiatric, developmental, medical, and neurocognitive conditions, often resulting in debilitating and long-term consequences. However, there is no available neuropsychological resource reviewing the literature on the associated neurocognitive deficits in children and adolescents. This review comprehensively examines the 23 prior studies that evaluated the intellectual, language, visual-spatial, memory, motor, and/or attention/executive functions in children and adolescents following an experience of childhood abuse and/or neglect. Neurocognitive impairments were frequently reported. Impairments in executive functions were the most frequent and severe reported impairments, although intelligence, language, visual-spatial skills, and memory are also at serious risk for compromised development following maltreatment. However, specific factors such as abuse/neglect duration, severity, type, and timing during development were all associated with neurocognition. This indicates that these factors are of greater importance than just the presence of abuse/neglect in identifying risk for neurocognitive compromise. Such neurocognitive deficits appear to be a consequence to the known neurobiological and brain development abnormalities of this population, suggesting traumatic stress can be a potential cause of neurodevelopmental disorders. These findings have critical implications for the clinical practice and research involving children following childhood maltreatment and other types of traumatic stress.

Abstract
The aim of this study was to investigate possible effects of antisocial behavior on reducing the association between subdimensions of ADHD symptoms (inattention, hyperactivity and impulsivity) and alcohol use. Boys and girls were analyzed separately using a population-based Swedish adolescent sample. A randomly selected cross-sectional survey was performed in secondary and upper secondary schools in Västmanland County during 2010. Participants were a population of 2,439 15-16 year-olds and 1,425 17-18 year-olds (1,947 girls and 1,917 boys). Psychosocial adversity, antisocial behaviors, symptoms of ADHD and alcohol use were assessed by questionnaires. Except for girls' inattention, subdimensions of ADHD symptoms were not associated with alcohol use when variance due to antisocial behavior was accounted for. Among boys, instead of an indirect effect of antisocial behavior on the association between impulsivity and alcohol use, a moderating effect was found. Among girls, the inattention component of ADHD was independently associated with alcohol use even when adjusted for antisocial behavior. The reduced associations between symptoms of hyperactivity, impulsivity, and alcohol use for boys and girls after adjusting for antisocial behavior suggest a considerable overlap between hyperactivity, impulsivity, and antisocial behavior. The direct pathway between inattention and alcohol use among girls suggests that girls with inattention symptoms are at risk of alcohol use regardless of antisocial behavior. Special attention should be given to these girls. Accounting for antisocial behavior reduced the relation between subdimensions of ADHD symptoms and alcohol use, and antisocial behaviors should therefore be screened for when symptoms of ADHD are present.
