| 1 | Single-cell RNA landscape of the special fiber initiation process in Bombax ceiba显示文摘As a new source of natural fibers,the Bombax ceiba tree can provide thin,light,extremely soft and warm fiber material for the textile industry.Natural fibers are an ideal model system for studying cell growth and differentiation,but the molecular mechanisms that regulate fiber initiation are not fully understood.In B.ceiba,we found that fiber cells differentiate from the epidermis of the inner ovary wall.Each initiated cell then divides into a cluster of fiber cells that eventually develop into mature fibers,a process very different from the classical fiber initiation process of cotton.We used high-throughput single-cell RNA sequencing(scRNA-seq)to examine the special characteristics of fiber initiation in B.ceiba.A total of 15567 high-quality cells were identified from the inner wall of the B.ceiba ovary,and 347 potential marker genes for fiber initiation cell types were identified.Two major cell types,initiated fiber cells and epidermal cells,were identified and verified by RNA in situ hybridization.A developmental trajectory analysis was used to reconstruct the process of fiber cell differentiation in B.ceiba.Comparative analysis of scRNAseq data from B.ceiba and cotton(Gossypium hirsutum)confirmed that the additional cell division process in B.ceiba is a novel species-specific mechanismfor fiber cell development.Candidate genes and key regulators that may contribute to fiber cell differentiation and division in B.ceiba were identified.This work reveals gene expression signatures during B.ceiba fiber initiation at a single-cell resolution,providing a new strategy and viewpoint for investigation of natural fiber cell differentiation and development. | Yuanhao Ding Wei Gao Yuan Qin Xinping Li Zhennan Zhang Wenjie Lai Yong Yang Kai Guo Ping Li Shihan Zhou Haiyan Hu | 2023 | Plant Communications2023，4，5： | 0 |
| 2 | Enhanced Beta2-band Oscillations Denote Auditory Hallucination in Schizophrenia Patients and a Monkey Model of Psychosis显示文摘An electroencephalographic(EEG)signature of auditory hallucinations(AHs)is important for facilitating the diagnosis and treatment of AHs in schizophrenia.We recorded EEG from 25 schizophrenia patients with recurrent AHs.During the period of AHs,EEG recordings exhibited significantly elevated beta2-band power in the temporal region,as compared to those recorded in the absence of AHs or during stimulation with verbal sounds.We further generated methamphetamine-treated rhesus monkeys exhibiting psychosis-like behaviors,including repetitive sudden searching actions in the absence of external intrusion,suggesting the occurrence of AHs.Epidural EEG beta2-band power in the temporal region of these monkeys was enhanced immediately after methamphetamine treatment and positively correlated with the frequency of sudden searching actions.Thus,the enhancement of temporal beta2-band oscillations represents a signature for AHs in both patients and a monkey model of psychosis,and this monkey model can be used for developing closed-loop neuromodulation approaches for the treatment of refractory AHs in schizophrenia. | Shuo Ma Tianzhen Chen Wenjun Jia Jie Liu Shihan Ding Puzhe Li Hong Gan Dapeng Zhang Shuxin Shao Mu-Ming Poo Min Zhao Bomin Sun Jian Jiang | 2024 | Neuroscience Bulletin2024，40，3： | 0 |
