| 2 | Glutamate transporters, EAAT1 and EAAT2, are potentially important in the pathophysiology and treatment of schizophrenia and affective disorders显示文摘Glutamate is the predominant excitatory neurotransmitter in the human brain and it has been shown that prolonged activation of the glutamatergic system leads to nerve damage and cell death. Following release from the pre-synaptic neuron and synaptic transmission, glutamate is either taken up into the presynaptic neuron or neighbouring glia by transmembrane glutamate transporters. Excitatory amino acid transporter(EAAT) 1 and EAAT2 are Na+-dependant glutamate transporters expressed predominantly in glia cells of the central nervous system. As the most abundant glutamate transporters, their primary role is to modulate levels of glutamatergic excitability and prevent spill over of glutamate beyond the synapse. This role is facilitated through the binding and transportation of glutamate into astrocytes and microglia. The function of EAAT1 and EAAT2 is heavily regulated at the levels of gene expression, post-transcriptional splicing, glycosylation states and cell-surface trafficking of the protein. Both glutamatergic dysfunction and glial dysfunction have been proposed to be involved in psychiatric disorder. This review will present an overview of the roles that EAAT1 and EAAT2 play in modulating glutamatergic activity in the human brain, and mount an argument that these two transporters could be involved in the aetiologies of schizophrenia and affective disorders as well as represent potential drug targets for novel therapies for those disorders. | Georgia M Parkin Madhara Udawela Andrew Gibbons Brian Dean | 2018 | World Journal of Psychiatry2018，8，2： | 9 |
| 3 | Biomarkers in schizophrenia:A focus on blood based diagnostics and theranostics显示文摘Identifying biomarkers that can be used as diagnostics or predictors of treatment response(theranostics) in people with schizophrenia(Sz) will be an important step towards being able to provide personalized treatment. Findings from the studies in brain tissue have not yet been translated into biomarkers that are practical in clinical use because brain biopsies are not acceptable and neuroimaging techniques are expensive and the results are inconclusive. Thus, in recent years, there has been search for blood-based biomarkers for Sz as a valid alternative. Although there are some encouraging preliminary data to support the notion of peripheral biomarkers for Sz, it must be acknowledged that Sz is a complex and heterogeneous disorder which needs to be further dissected into subtype using biological based and clinical markers. The scope of this review is to critically examine published blood-based biomarker of Sz, focusing on possible uses for diagnosis, treatment response, or their relationship with schizophreniaassociated phenotype. We sorted the studies into six categories which include:(1) brain-derived neurotrophic factor;(2) inflammation and immune function;(3) neurochemistry;(4) oxidative stress response and metabolism;(5) epigenetics and micro RNA; and(6) transcriptome and proteome studies. This review also summarized the molecules which have been conclusively reported as potential blood-based biomarkers for Sz in different blood cell types. Finally, we further discusses the pitfall of current blood-based studies and suggest that a prediction model-based, Sz specific, bloodoriented study design as well as standardize blood collection conditions would be useful for Sz biomarker development. | Chi-Yu Lai Elizabeth Scarr Madhara Udawela Ian Everall Wei J Chen Brian Dean | 2016 | World Journal of Psychiatry2016，6，1： | 6 |
| 4 | 籼稻开花期耐热性鉴定与QTL定位分析显示文摘高温热害是水稻生产的重要制约因素之一。本研究利用籼稻恢复系蜀恢527为轮回亲本,以来自不同来源的6个籼稻品种为供体亲本构建了131个BC2F3:4选择导入系群体,在正常大田和温室大棚高温胁迫条件下进行连续两年(2011年和2012年)的耐热性鉴定,并结合基因型分析进行产量相关性状和耐热性QTL定位。耐热表型分析结果表明,尽管轮回亲本和供体本身不具备很强的耐热性,但绝大多数导入系后代出现了耐热性的超亲分离。本研究通过分子标记基因型和表型分析的单向方差分析进行产量相关性状(每穗总粒数,结实率,千粒重,单株产量)和耐热性(热胁迫指数)QTL发掘,共定位的到39个产量相关性状QTL,贡献率为7.3%-39.7%和12个耐热性QTL,贡献率为14.7%-30.2%。12个耐热性QTL中,有9个也在产量相关性状中检测到。40例QTL有利等位基因来自供体亲本,61.5%的QTL能在不同群体或环境中被重复检测到。产量性状和耐热性QTL在染色体上大多成簇分布,每个簇往往同时影响几个性状(多效性)。其中,第2染色体上RM341(Bin2.8)对每穗总粒数、千粒重和单株产量影响较大;第7染色体RM051(Bin7.1)则是主要控制结实率、单株产量和耐热指数等性状。第10染色体RM258(Bin10.5)则是主要控制每穗总粒数和耐热指数等性状。研究结果将为水稻耐热性改良及其分子标记辅助育种提供有益信息。 | 刘周 唐启源 李飞 U.A.Kapila Siri Udawela 项超 高用明 石英尧 | 2015 | 分子植物育种2015，13，1： | 5 |
| 5 | Allosteric modulation of cholinergic system:Potential approach to treating cognitive deficits of schizophrenia显示文摘Schizophrenia is a psychiatric disorder affecting approximately 1% of the population worldwide and is characterised by the presence of positive and negative symptoms and cognitive deficits. Whilst current therapeutics ameliorate positive symptoms, they are largely ineffective in improving negative symptoms and cognitive deficits. The cholinergic neurotransmitter system heavily influences cognitive function and there is evidence that implicates disruption of the central cholinergic system in schizophrenia. Historically, targeting the cholinergic system has been impeded by poor selectivity leading to intolerable side effects warranting the need to develop more targeted therapeutic compounds. In this review we will summarise evidence supporting the roles of the cholinergic system, particularly the muscarinic M1 receptor, in the pathophysiology of schizophrenia and discuss the potential of a promising new class of candidate compounds, allosteric ligands, for addressing the difficulties involved in targeting this system. The body of evidence presented here highlights the dysfunction of the cholinergic system in schizophrenia and that targeting this system by taking advantage of allosteric ligands is having clinically meaningful effect on cognitive deficits. | Shaun Hopper Madhara Udawela Elizabeth Scarr Brian Dean | 2016 | World Journal of Pharmacology2016，5，1： | 3 |
