| 1 | Fast-Suppressor Screening for New Components in Protein Trafficking,Organelle Biogenesis and Silencing Pathway in Arabidopsis thaliana Using DEX-Inducible FREE1-RNAi Plants显示文摘Membrane trafficking is essential for plant growth and responses to external signals.The plant unique FYVE domain-containing protein FREE1 is a component of the ESCRT complex(endosomal sorting complex required for transport).FREE1 plays multiple roles in regulating protein trafficking and organelle biogenesis including the formation of intraluminal vesicles of multivesicular body(MVB),vacuolar protein transport and vacuole biogenesis,and autophagic degradation.FREE1 knockout plants show defective MVB formation,abnormal vacuolar transport,fragmented vacuoles,accumulated autophagosomes,and seedling lethality.To further uncover the underlying mechanisms of FREE1 function in plants,we performed a forward genetic screen for mutants that suppressed the seedling lethal phenotype of FREE1-RNAi transgenic plants.The obtained mutants are termed as suppressors of free1(sof).To date,229 putative sof mutants have been identified.Barely detecting of FREE1 protein with M3plants further identified 84 FREE1-related suppressors.Also145 mutants showing no reduction of FREE1 protein were termed as RNAi-related mutants.Through next-generation sequencing(NGS)of bulked DNA from F2mapping population of two RNAi-related sof mutants,FREE1-RNAi T-DNA inserted on chromosome 1 was identified and the causal mutation of putative sof mutant is being identified similarly.These FREE1-and RNAi-related sof mutants will be useful tools and resources for illustrating the underlying mechanisms of FREE1 function in intracellular trafficking and organelle biogenesis,as well as for uncovering the new components involved in the regulation of silencing pathways in plants. | Qiong Zhao Caiji Gao PoShing Lee Lin Liu Shaofang Li Tangjin Hu Jinbo Shen Shuying Pan Hao Ye Yunru Chen Wenhan Cao Yong Cui Peng Zeng Sheng Yu Yangbin Gao Liang Chen Beixin Mo Xin Liu Shi Xiao Yunde Zhao Silin Zhong Xuemei Chen Liwen Jiang | 2015 | Journal of Genetics and Genomics2015，42，6： | 4 |
| 2 | Neuro-11:a new questionnaire for the assessment of somatic symptom disorder in general hospitals显示文摘Background Somatic symptom disorder(SSD)commonly presents in general hospital settings,posing challenges for healthcare professionals lacking specialised psychiatric training.The Neuro-11 Neurosis Scale(Neuro-11)offers promise in screening and evaluating psychosomatic symptoms,comprising 11 concise items across three dimensions:somatic symptoms,negative emotions and adverse events.Prior research has validated the scale’s reliability,validity and theoretical framework in somatoform disorders,indicating its potential as a valuable tool for SSD screening in general hospitals.Aims This study aimed to establish the reliability,validity and threshold of the Neuro-11 by comparing it with standard questionnaires commonly used in general hospitals for assessing SSD.Through this comparative analysis,we aimed to validate the effectiveness and precision of the Neuro-11,enhancing its utility in clinical settings.Methods Between November 2020 and December 2021,data were collected from 731 patients receiving outpatient and inpatient care at Shenzhen People’s Hospital in China for various physical discomforts.The patients completed multiple questionnaires,including the Neuro-11,Short Form 36 Health Survey,Patient Health Questionnaire 15 items,Hamilton Anxiety Scale and Hamilton Depression Scale.Psychiatry-trained clinicians conducted structured interviews and clinical examinations to establish a gold standard diagnosis of SSD.Results The Neuro-11 demonstrated strong content reliability and structural consistency,correlating significantly with internationally recognised and widely used questionnaires.Despite its brevity,the Neuro-11 exhibited significant correlations with other questionnaires.A test-retest analysis yielded a correlation coefficient of 1.00,Spearman-Brown coefficient of 0.64 and Cronbach’sαcoefficient of 0.72,indicating robust content reliability and internal consistency.Confirmatory factor analysis confirmed the validity of the three-dimensional structure(p<0.001,comparative fit index=0.94,Tucker-Lewis index=0.92,root mean square error of approximation=0.06,standardised root mean square residual=0.04).The threshold of the Neuro-11 is set at 10 points based on the maximum Youden’s index from the receiver operating characteristic curve analysis.In terms of diagnostic efficacy,the Neuro-11 has an area under the curve of 0.67. | Silin Zeng Yian Yu Shan Lu Sirui Zhang Xiaolin Su Ge Dang Ying Liu Zhili Cai Siyan Chen Yitao He Xin Jiang Chanjuan Chen Lei Yuan Peng Xie Jianqing Shi Qingshan Geng Rafael H Llinas Yi Guo | 2023 | General Psychiatry2023，36，4： | 0 |
