Redox Biol 2020; 34:101487. [PMID: 32173345 PMCID: PMC7327963 DOI: 10.1016/j.redox.2020.101487] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Revised: 02/27/2020] [Accepted: 02/29/2020] [Indexed: 02/07/2023] Open
Abstract
Endothelial nitric oxide (NO) is a critical mediator of vascular function and vascular remodeling. NO is produced by endothelial nitric oxide synthase (eNOS), which is activated by calcium (Ca2+)-dependent and Ca2+-independent pathways. Here, we report that neurogranin (Ng), which regulates Ca2+-calmodulin (CaM) signaling in the brain, is uniquely expressed in endothelial cells (EC) of human and mouse vasculature, and is also required for eNOS regulation. To test the role of Ng in eNOS activation, Ng knockdown in human aortic endothelial cells (HAEC) was performed using Ng SiRNA along with Ng knockout (Ng −/−) in mice. Depletion of Ng expression decreased eNOS activity in HAEC and NO production in mice. We show that Ng expression was decreased by short-term laminar flow and long-them oscillating flow shear stress, and that Ng siRNA with shear stress decreased eNOS expression as well as eNOS phosphorylation at S1177. We further reveled that lack of Ng expression decreases both AKT-dependent eNOS phosphorylation, NF-κB-mediated eNOS expression, and promotes endothelial activation. Our findings also indicate that Ng modulates Ca2+-dependent calcineurin (CaN) activity, which suppresses Ca2+-independent AKT-dependent eNOS signaling. Moreover, deletion of Ng in mice also reduced eNOS activity and caused endothelial dysfunction in flow-mediated dilation experiments. Our results demonstrate that Ng plays a crucial role in Ca2+-CaM-dependent eNOS regulation and contributes to vascular remodeling, which is important for the pathophysiology of cardiovascular disease. Neurogranin is expressed in endothelial cell and is required for eNOS regulation. Short-term laminar flow and long-them oscillating flow decrease Neurogranin expression in endothelial cells. Neurogranin knockdown decreases both AKT-dependent eNOS phosphorylation and eNOS expression. Deletion of Ng in mice reduces eNOS activity and caused endothelial dysfunction in flow-mediated dilation.

Abstract
BACKGROUND The correlation between single nucleotide polymorphism (SNP) rs12807809 in Neurogranin (NRGN) gene and Schizophrenia (SCZ) was investigated by several studies, whereas the results were conflicting. Thus, we performed the present meta-analysis to combine and analyze the available studies in order to provide a more accurate result on the association of rs12807809 polymorphism in NRGN gene and SCZ vulnerability. METHODS A comprehensive retrieval in PubMed, EMBASE, Web of Science, Cochrane Library and Wanfang was performed for relevant studies on the relationship of rs12807809 polymorphism and SCZ. Summary odds ratios (OR) with 95% confidence interval (95% CI) were calculated in allelic, homozygous, heterozygous, dominant and recessive model to appraise the association. RESULTS The meta-analysis included 8 studies containing 12552 SCZ cases and 34783 controls. The results showed a statistically significant correlation between SCZ and rs12807809 polymorphism in overall population in allelic model (OR = 1.10, 95%CI 1.04-1.17). However, subgroup analysis indicated the association only existed in Caucasians but not Asian. CONCLUSION The results of present meta-analysis suggested significant association between SNP rs12807809 in NRGN gene and SCZ susceptibility in Caucasians but not Asians.

Abstract
Aggressive behavior exerts an enormous impact on society remaining among the main causes of worldwide premature death. Effective primary interventions, relying on predictive models of aggression that show adequate sensitivity and specificity are currently lacking. One strategy to increase the accuracy and precision of prediction would be to include biological data in the predictive models. Clearly, to be included in such models, biological markers should be reliably associated with the specific trait under study (i.e., diagnostic biomarkers). Aggression, however, is phenotypically highly heterogeneous, an element that has hindered the identification of reliable biomarkers. However, current research is trying to overcome these challenges by focusing on more homogenous aggression subtypes and/or by studying large sample size of aggressive individuals. Further advance is coming by bioinformatics approaches that are allowing the integration of inter-species biological data as well as the development of predictive algorithms able to discriminate subjects on the basis of the propensity toward aggressive behavior. In this review we first present a brief summary of the available evidence on neuroimaging of aggression. We will then treat extensively the data on genetic determinants, including those from hypothesis-free genome-wide association studies (GWAS) and candidate gene studies. Transcriptomic and neurochemical biomarkers will then be reviewed, and we will dedicate a section on the role of metabolomics in aggression. Finally, we will discuss how biomarkers can inform the development of new pharmacological tools as well as increase the efficacy of preventive strategies.

Association between NRGN gene polymorphism and resting-state hippocampal functional connectivity in schizophrenia. BMC Psychiatry 2019; 19:108. [PMID: 30953482 PMCID: PMC6451258 DOI: 10.1186/s12888-019-2088-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2018] [Accepted: 03/24/2019] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Based on genome-wide association studies, a single-nucleotide polymorphism in the NRGN gene (rs12807809) is considered associated with schizophrenia (SZ). Moreover, hippocampal dysfunction is associated with rs12807809. In addition, converging evidence suggests that hippocampal dysfunction is involved in SZ pathophysiology. However, the association among rs12807809, hippocampal dysfunction and SZ pathophysiology is unknown. Therefore, this study investigated the association between rs12807809 and hippocampal functional connectivity at rest in SZ. METHODS In total, 158 participants were studied, including a C-carrier group carrying the non-risk C allele (29 SZ patients and 46 healthy controls) and a TT homozygous group carrying the risk T allele (30 SZ patients and 53 healthy controls). All participants were scanned using resting-state functional magnetic resonance imaging. Hippocampal functional connectivity was computed and compared among the 4 groups. RESULTS Significant main effects of diagnosis were observed in the functional connectivity between the hippocampus and bilateral fusiform gyrus, bilateral lingual gyrus, left inferior temporal gyrus, left caudate nucleus, bilateral thalamus and bilateral anterior cingulate gyri. In contrast, no significant main effect of genotype was found. In addition, a significant genotype by diagnosis interaction in the functional connectivity between the hippocampus and left anterior cingulate gyrus, as well as bilateral middle cingulate gyri, was observed, with TT homozygotes with SZ showing less functional connectivity than C-carriers with SZ and healthy control TT homozygotes. CONCLUSIONS These findings are the first to suggest an association between rs12807809 and abnormal Papez circuit function in patients with SZ. This study also implicates NRGN variation and abnormal Papez circuit function in SZ pathophysiology.

Neurogranin regulates sensorimotor gating through cortico-striatal circuitry. Neuropharmacology 2019; 150:91-99.

Abstract
Glutamate dysregulation is known to contribute to many psychiatric disorders including schizophrenia. Aberrant cortico-striatal activity and therefore glutamate levels might be relevant to this disease characterized by reduced prepulse inhibition (PPI), however, the molecular and behavioral mechanism of the pathophysiology of schizophrenia remains unclear. The focus of this study was to contribute to the current understanding of the glutamate and neurogranin (Ng) pathway, in relation to the cortico-striatal pathology of schizophrenia using a mouse model. A variant of the Ng gene has been detected in people with schizophrenia, implicating maladaptation of cortical glutamate signaling and sensorimotor gating. To test Ng-mediated PPI regulation in the mouse model, we utilized Ng null mice, viral-mediated Ng expression, and genetics approaches. Our results demonstrate that lack of Ng in mice decreases PPI. Ng over-expression in the prefrontal cortex (PFC) increases PPI, while Ng expression in either the nucleus accumbens (NAc) or hippocampus induces no change in PPI. Using optogenetics and chemogenetics, we identified that cortico-striatal activation is involved in PPI regulation. Finally, pharmacological regulation of Ng using glutamate receptor inhibitors demonstrated altered PPI between genotypes. In this study, we have investigated the impact of Ng expression on sensorimotor gating. This study contributes to a better understanding of the glutamatergic theory of schizophrenia, opening novel therapeutic avenues that may lead to glutamatergic treatments to ameliorate the symptoms of schizophrenia.

Abstract
Schizophrenia (SCZ) as a severe and complex neuropsychiatric disorder and is characterized by positive symptoms, negative symptoms and cognitive dysfunctions. Genome-wide association studies (GWAS) have identified a strong association between the single nucleotide polymorphism (SNP) rs12807809 upstream of Neurogranin (NRGN) in a European population. This evidence prompted us to conduct an association study among 1005 schizophrenia cases and 1069 controls in a South Indian Population using TaqMan Allelic discrimination method. We observed an association of rs12807809 with SCZ in this study population. Allele frequencies and genotype frequencies of rs12807809 showed significant differences between cases and control subjects [p=0.0019; OR=0.69; 95% CI=(0.55-0.87)] and (p=0.0062). Further Genotype-Phenotype correlation revealed a moderate association of rs12807809 with flat affect (p=0.039) and Hallucinations (p=0.012). The ancestral non-risk C allele contributes to the severity of psychosis (p=0.039) in this population.

Abstract
The present study aimed to investigate the association of two polymorphisms (rs2844337 and rs11237200) in the P21 protein (cell division control protein 42/Rac)-activated kinase 1 gene with susceptibility to schizophrenia (SCZ) in Chinese Zhuang and Chinese Han populations. A total of 700 patients with SCZ and 700 healthy controls were recruited. Rs2844337 and rs11237200 polymorphisms were genotyped using Sequenom technology. A total of 591 patients completed the Positive and Negative Syndrome Scale (PANSS) assessment. Data were statistically analyzed using PLINK version 1.07 and SPSS version 17.0. In the Chinese Han population, the genotypic (P=0.038) and allelic (P=0.033) frequencies of the 3'-untranslated region (UTR) genetic variation of rs2844337 in patients were significantly decreased compared to that in controls; these frequencies were significantly associated with SCZ susceptibility in the additive model (Padj=0.032) and in the recessive model (Padj=0.031). Moreover, the TG haplotype constructed by rs2844337 and rs11237200 polymorphisms remained significantly associated with SCZ risk following adjustment for gender and age and applying a Bonferroni correction in the Chinese Han population (Padj=0.003, PBC=0.009). The adjacent 5'-UTR genetic variation of rs11237200 was significantly associated with the total score (Padj=0.006), positive scale score (Padj=0.014) and general psychopathology scale scores (Padj=0.009) in the recessive model of the Chinese Han population. However, these polymorphisms were not significantly associated with SCZ susceptibility or the PANSS scores in the Chinese Zhuang population. In conclusion, variations in the PAK1 gene influenced the susceptibility and severity of the clinical symptoms of SCZ in the Chinese Han population investigated in the present study.

Polymorphisms in NRGN are associated with schizophrenia, major depressive disorder and bipolar disorder in the Han Chinese population. J Affect Disord 2016; 194:180-7.

Abstract
BACKGROUND The NRGN gene locates on 11q24 and encodes a postsynaptic protein kinase substrate that binds calmodulin in the absence of calcium. In a previous genome-wide association study of schizophrenia in the Caucasian population, rs12807809 of NRGN was found to be significantly associated with schizophrenia, moreover, it was further found to be associated with bipolar disorder. METHODS We recruited 1248 schizophrenia cases, 1344 bipolar disorder cases, 1056 major depressive disorder cases, and 1248 healthy controls from Han Chinese population. Rs12807809 and another two tag SNPs of NRGN were genotyped and analyzed in three diseases respectively. A meta-analysis of rs12807809 was also conducted to verify its association with schizophrenia in Han Chinese population. RESULTS Rs7113041 was associated with bipolar disorder (odds ratio, 95% confidence interval (OR, 95% CI)=1.194, 1.032-1.383; Pgenotype=0.0126), and rs12278912 was associated with major depressive disorder (OR, 95% CI=0.789, 0.673-0.924; Pallele=0.0102, Pgenotype=0.0399) after Bonferroni correction. The "GA" haplotype of rs7113041-rs12278912 was significantly associated with schizophrenia, major depressive disorder and bipolar disorder (corresponding P values were 2.85E-04, 3.00E-03, and 5.40E-04 after Bonferroni correction). LIMITATIONS Despite the association between NRGN and psychoses we have found, we failed to validate the positive variant rs12807809, which was reported in the Caucasian genome-wide association study both in our single site association test and the meta-analysis. Functional studies are needed to illuminate the role of NRGN in the pathogenesis of these mental disorders. CONCLUSIONS Our findings prove that NRGN is a shared susceptibility gene of schizophrenia, major depression and bipolar disorder in Han Chinese, and this might provide a new target for the diagnosis and treatment of these mental disorders.

Abstract
Schizophrenia (SCZ) is a severe neuropsychiatric disorder with high heritability. A recent European genome-wide association study has reported that mitotic arrest deficient-like 1 (MAD1L1) polymorphism rs12666575 is associated with SCZ susceptibility. This study aims to test the association of MAD1L1 variant rs12666575 with SCZ susceptibility in a Chinese population. A total of 1400 participants, which include 700 SCZ patients and 700 sex- and age-matched controls (Zhuang: 300, Han: 400, respectively), were genotyped using the Sequenom MassARRAY iPLEX platform. 591 SCZ patients underwent positive and negative syndrome scale (PANSS) assessment. Genetic association analysis was performed using the PLINK program. The results showed MAD1L1 rs12666575 polymorphism was significantly associated with SCZ susceptibility in the recessive model (p(adj)=0.013). Also, rs12666575 was significantly associated with general psychopathology sub-scale score (p(adj)=0.043) and thought disturbance factor score (p(adj)=0.045). Our data suggested that MAD1L1 rs12666575 polymorphism may play a protective role against SCZ in the Chinese population. Furthermore, rs12666575 may be associated with general psychopathology and thought disturbance in SCZ patients.
