| 1 | Distinct neuronal excitability alterations of medial prefrontal cortex in early-life neglect model of rats显示文摘Object:Early-life neglect has irreversible emotional effects on the central nervous system.In this work,we aimed to elucidate distinct functional neural changes in me-dial prefrontal cortex(mPFC)of model rats.Methods:Maternal separation with early weaning was used as a rat model of early-life neglect.The excitation of glutamatergic and GABAergic neurons in rat mPFC was recorded and analyzed by whole-cell patch clamp.Results:Glutamatergic and GABAergic neurons of mPFC were distinguished by typi-cal electrophysiological properties.The excitation of mPFC glutamatergic neurons was significantly increased in male groups,while the excitation of mPFC GABAergic neurons was significant in both female and male groups,but mainly in terms of rest membrane potential and amplitude,respectively.Conclusions:Glutamatergic and GABAergic neurons in medial prefrontal cortex showed different excitability changes in a rat model of early-life neglect,which can contribute to distinct mechanisms for emotional and cognitive manifestations. | Yu Zhang Xiuping Sun Changsong Dou Xianglei Li Ling Zhang Chuan Qin | 2022 | Animal Models and Experimental Medicine2022,5,3: | 2 |
| 2 | A genome-wide identification of the BLH gene family reveals BLH1 involved in cotton fiber development显示文摘Background:Cotton is the world’s largest and most important source of renewable natural fiber.BEL1-like homeodomain(BLH)genes are ubiquitous in plants and have been reported to contribute to plant development.However,there is no comprehensive characterization of this gene family in cotton.In this study,32,16,and 18 BLH genes were identified from the G.hirsutum,G.arboreum,and G.raimondii genome,respectively.In addition,we also studied the phylogenetic relationships,chromosomal location,gene structure,and gene expression patterns of the BLH genes.Results:The results indicated that these BLH proteins were divided into seven distinct groups by phylogenetic analysis.Among them,25 members were assigned to 15 chromosomes.Furthermore,gene structure,chromosomal location,conserved motifs,and expression level of BLH genes were investigated in G.hirsutum.Expression profiles analysis showed that four genes(GhBLH1_3,GhBLH1_4,GhBLH1_5,and GhBLH1_6)from BLH1 subfamily were highly expressed during the fiber cell elongation period.The expression levels of these genes were significantly induced by gibberellic acid and brassinosteroid,but not auxin.Exogenous application of gibberellic acid significantly enhanced GhBLH1_3,GhBLH1_4,and GhBLH1_5 transcripts.Expression levels of GhBLH1_3 and GhBLH1_4 genes were significantly increased under brassinosteroid treatment.Conclusions:The BLH gene family plays a very important role in many biological processes during plant growth and development.This study deepens our understanding of the role of the GhBLH1 gene involved in fiber development and will help us in breeding better cotton varieties in the future. | LIU Cuixia LI Zhifang DOU Lingling YUAN Yi ZOU Changsong SHANG Haihong CUI Langjun XIAO Guanghui | 2020 | Journal of Cotton Research2020,3,3: | 1 |
| 3 | Patterns of presence-absence variants in Upland cotton显示文摘Dear Editor,Sources of genetic variations in genomes include small-scale sources(such as single-nucleotide polymorphisms(SNPs),insertions/deletions(InDels),and simple sequence repeats and larger-scale structural variations(mainly presence-absence variants(PAVs))and copy number variants).PAVs are sequences that are either inserted or missing in genomes in comparison with a reference sequence or genome.PAVs can have a much longer sequence than SNPs and InDels,as illustrated in the human genome(Conrad et al.,2010).PAVs are important genomic structural variations that can directly affect genomic structure and key functional genes in the genome(Kumar et al.,2007).Moreover,the use of PAVs for studying quantitative traits has been valuable(Lam et al.,2010). | Junfang Liu Xianliang Zhang Lingling Dou Wei Li Xiaojian Zhou Yangai Liu Xiaoyu Pei Zhongying Ren Wensheng Zhang Huaizhu Li Wenbo Wang Changsong Zou Kunlun He Fei Zhang Wenyu Ma Haihong Shang Hongbin Li Daigang Yang Guanghui Xiao Xiongfeng Ma | 2020 | Science China(Life Sciences)2020,63,10: | 0 |
| 4 | Genome-wide identification and expression analysis of the GhIQD gene family in upland cotton(Gossypium hirsutum L.)显示文摘Background:Calmodulin(CaM)is one of the most important Ca^(2+)signaling receptors because it regulates diverse physiological and biochemical reactions in plants.CaM functions by interacting with CaM-binding proteins(CaMBPs)to modulate Ca^(2+)signaling.IQ domain(IQD)proteins are plant-specific CaMBPs that bind to CaM by their specific CaM binding sites.Results:In this study,we identified 102 GhIQD genes in the Gossypium hirsutum L.genome.The GhIQD gene family was classified into four clusters(Ⅰ,Ⅱ,Ⅲ,andⅣ),and we then mapped the GhIQD genes to the G.hirsutum L.chromosomes.Moreover,we found that 100 of the 102 GhIQD genes resulted from segmental duplication events,indicating that segmental duplication is the main force driving GhIQD gene expansion.Gene expression pattern analysis showed that a total of 89 GhIQD genes expressed in the elongation stage and second cell wall biosynthesis stage of the fiber cells,suggesting that GhIQD genes may contribute to fiber cell development in cotton.In addition,we found that 20 selected GhIQD genes were highly expressed in various tissues.Exogenous application of MeJA significantly enhanced the expression levels of GhIQD genes.Conclusions:Our study shows that GhIQD genes are involved in fiber cell development in cotton and are also widely induced by MeJA.Thw results provide bases to systematically characterize the evolution and biological functions of GhIQD genes,as well as clues to breed better cotton varieties in the future. | DOU Lingling LV Limin KANG Yangyang TIAN Ruijie HUANG Deqing LI Jiayin LI Siyi LIU Fengping CAO Lingyan JIN Yuhua LIU Yang LI Huaizhu WANG Wenbo PANG Chaoyou SHANG Haihong ZOU Changsong SONG Guoli XIAO Guanghui | 2021 | Journal of Cotton Research2021,4,1: | 0 |
| 5 | Autophagy and autophagy-related molecules in neurodegenerative diseases显示文摘Autophagy is one of the degradation pathways to remove proteins or damaged or-ganelles in cells that plays an important role in neuroprotection.Different stages of autophagy are regulated by autophagy-related genes,and many molecules such as transcription factor EB(TFEB)are involved.The complete autophagy process plays an important role in maintaining the dynamic balance of autophagy and is crucial to the homeostasis of intracellular substance and energy metabolism.Autophagy balance is disrupted in neurodegenerative diseases,accounting for a variety of degeneration dis-orders.These impairments can be alleviated or treated by the regulation of autophagy through molecules such as TFEB. | Changsong Dou Yu Zhang Ling Zhang Chuan Qin | 2023 | Animal Models and Experimental Medicine2023,6,1: | 0 |
