1Converting lateral scanning into axial focusing to speed up three-dimensional microscopy显示文摘In optical microscopy,the slow axial scanning rate of the objective or the sample has traditionally limited the speed of volumetric imaging.Recently,by conjugating either a movable mirror to the image plane in a remote-focusing geometry or an electrically tuneable lens(ETL)to the back focal plane,rapid axial scanning has been achieved.However,mechanical actuation of a mirror limits the axial scanning rate(usually only 10–100 Hz for piezoelectric or voice coil-based actuators),while ETLs introduce spherical and higher-order aberrations that prevent high-resolution imaging.In an effort to overcome these limitations,we introduce a novel optical design that transforms a lateral-scan motion into a spherical aberration-free axial scan that can be used for high-resolution imaging.Using a galvanometric mirror,we scan a laser beam laterally in a remote-focusing arm,which is then back-reflected from different heights of a mirror in the image space.We characterize the optical performance of this remote-focusing technique and use it to accelerate axially swept light-sheet microscopy by an order of magnitude,allowing the quantification of rapid vesicular dynamics in three dimensions.We also demonstrate resonant remote focusing at 12 kHz with a two-photon raster-scanning microscope,which allows rapid imaging of brain tissues and zebrafish cardiac dynamics with diffraction-limited resolution.Tonmoy Chakraborty Bingying Chen Stephan Daetwyler Bo-Jui Chang Oliver Vanderpoorten Etai Sapoznik Clemens F.Kaminski Tuomas P.J.Knowles Kevin M.Dean Reto Fiolka 2020Light(Science & Applications)2020,9,1:4
2The genome of the recretohalophyte Limonium bicolor provides insights into salt gland development and salinity adaptation during terrestrial evolution显示文摘Halophytes have evolved specialized strategies to cope with high salinity.The extreme halophyte sea lavender(Limonium bicolor)lacks trichomes but possesses salt glands on its epidermis that can excrete harmful ions,such as sodium,to avoid salt damage.Here,we report a high-quality,2.92-Gb,chromosome-scale L.bicolor genome assembly based on a combination of Illumina short reads,single-molecule,real-time long reads,chromosome conformation capture(Hi-C)data,and Bionano genome maps,greatly enriching the genomic information on recretohalophytes with multicellular salt glands.Although the L.bicolor genome contains genes that show similarity to trichome fate genes from Arabidopsis thaliana,it lacks homologs of the decision fate genes GLABRA3,ENHANCER OF GLABRA3,GLABRA2,TRANSPARENT TESTA GLABRA2,and SIAMESE,providing a molecular explanation for the absence of trichomes in this species.We identified key genes(LbHLH and LbTTG1)controlling salt gland development among classical trichome homologous genes and confirmed their roles by showing that their mutations markedly disrupted salt gland initiation,salt secretion,and salt tolerance,thus offering genetic support for the long-standing hypothesis that salt glands and trichomes may share a common origin.In addition,a whole-genome duplication event occurred in the L.bicolor genome after its divergence from Tartary buckwheat and may have contributed to its adaptation to high salinity.The L.bicolor genome resource and genetic evidence reported in this study provide profound insights into plant salt tolerance mechanisms that may facilitate the engineering of salt-tolerant crops.Fang Yuan Xi Wang Boqing Zhao Xiaojing Xu Miao Shi Bingying Leng Xinxiu Dong Chaoxia Lu Zhongtao Feng Jianrong Guo Guoliang Han Haikuan Zhang Jianwei Huang Min Chen Bao-Shan Wang 2022Molecular Plant2022,15,6:3
3Molecular imaging of tumor angiogenesis using RGD-labeled iron oxide nanoparticles显示文摘Integrin is often significantly up-regulated in activated endothelial cells during tumor angiogenesis.The arginine-glycine-aspartic acid(RGD)peptide sequence is a specific recognition motif toανβ3 integrin.In this study,a RGD labeled,Poly lactic acid(PLA) coated ultrasmall paramagnetic iron oxide(USPIO)(referred to as RGD-PLA-USPIO)were developed and the ability to detect tumor angiogenesis was investigated in vitro and in vivo.Increased uptake of RGD-PLA-USPIO by human umbilical vein endothelial cells(HUVECs)was detected by Prussian blue stain and transmission electronic microscopy(TEM).Pronounced signal decrease in T2*-weighted magnetic resonance image(MRI)and heterogeneous arrangement of neovasculature of tumor tissue were clearly identified in Vx-2 tumor model.The MR signal of contralateral muscle only could be seen a slight background change after either RGD-PLA-USPIO or PLA-USPIO injection.These studies demonstrate the efficiency of RGD-PLA-USPIO to visualizeανβ3 integrin in activated tumor endothelial cells and its potential for detecting and monitoring tumor vasculature change after therapy.WU XinYing ZHANG JingFeng LIN BingYing ZHANG MinMing 2010Chinese Science Bulletin2010,55,24:3
4SP1 governs primordial folliculogenesis by regulating pregranulosa cell development in mice显示文摘Establishment of the primordial follicle(PF)pool is pivotal for the female reproductive lifespan;however,the mechanism of primordial folliculogenesis is poorly understood.Here,the transcription factor SP1 was shown to be essential for PF formation in mice.Our results showed that SP1 is present in both oocytes and somatic cells during PF formation in the ovary.Knockdown of Sp1 expression,especially in pregranulosa cells,significantly suppressed nest breakdown,oocyte apoptosis,and PF formation,suggesting that SP1 expressed by somatic cells functions in the process of primordial folliculogenesis.We further demonstrated that SP1 governs the recruitment and maintenance of Forkhead box L2-positive(FOXL2^+)pregranulosa cells using an Lgr5-EGFP-IRES-CreER^T2(Lgr5-KI)reporter mouse model and a FOXL2^+ cell-specific knockdown model.At the molecular level,SP1 functioned mainly through manipulation of NOTCH2 expression by binding directly to the promoter of the Notch2 gene.Finally,consistent with the critical role of granulosa cells in follicle survival in vitro,massive loss of oocytes in SP1 knockdown ovaries was evidenced before puberty after the ovaries were tranSP1anted under the renal capsules.Conclusively,our results reveal that SP1 controls the establishment of the ovarian reserve by regulating pregranulosa cell development in the mammalian ovary.Han Cai Bingying Liu Huarong Wang Guanghong Sun Lizhao Feng Ziqi Chen Jiaqi Zhou Jiawei Zhang Tuo Zhang Meina He Tingting Yang Qirui Guo Zhen Teng Qiliang Xin Bo Zhou Hua Zhang Guoliang Xia Chao Wang 2020Journal of Molecular Cell Biology2020,12,3:3
5p53-dependent upregulation of PIG3 transcription by γ-ray irradiation and its interaction with KAP1 in responding to DNA damage显示文摘PIG3 (p53-inducible gene 3), originally identified as one of a set of genes induced by p53 before the onset of apoptosis, was assumed to contribute to early cellular response to DNA damage. Here, we studied the relation between p53 status and the increased expression of PIG3 by ionizing radiation (IR), and the related clues regarding the involvement of PIG3 in the cellular response to IR-induced DNA damage signaling. We demonstrated that the pentanucleotide microsatellite sequence was responsible for the p53-dependent induction of PIG3 transcription after irradiation, while sequence upstream of PIG3 promoter could maintain the basal level of expression which was not inducible by irradiation. The interaction of PIG3 and the KRAB-ZFP-associated protein 1 (KAP1), a DNA damage response protein, was revealed. PIG3 nucleus foci were formed 15 min after γ-ray irradiation, and which were found to partially colocalize with the phospho-KAP-1 foci as well as γ-H2AX foci. Although the lac operator tagged EGFP based reporter system revealed that PIG3 does not remodel chromatin in large scale in the cells under normal growing condition, it indeed prompted the chromatin relaxation in the cellular response to DNA damage signaling. All these data suggest that PIG3 is involved in IR-induced DNA damage response, and which maybe partially attribute to its interaction with KAP1.QIN Xia ZHANG ShiMeng LI Bingi LIU XiaoDan HE XingPeng SHANG ZengFu XU QinZhi ZHAO ZengQiang YE QiNong ZHOU PingKun 2011Chinese Science Bulletin2011,56,30:2

7Postnatal state transition of cardiomyocyte as a primary step in heart maturation显示文摘Postnatal heart maturation Is the basis of normal cardiac function and provides critical insights into heart repair and regenerative medicine.While static snapshots of the maturing heart have provided much Insight into its molecular signatures,few key events during postnatal cardiomyocyte maturation have been uncovered.Here,we report that cardiomyocytes(CMs)experience epige-netic and transcriptional decline of cardiac gene expression immediately after birth,leading to a transi-tion state of CMs at postnatal day 7(P7)that was essential for CM subtype specification during heart maturation.Large-scale single-cell analysis and genetic lineage tracing confirm the presence of transition state CMs at P7 bridging immature state and mature states.Silencing of key transcription factor JUN In P1-hearts significantly repressed CM transition,resulting in per-turbed CM subtype proportions and reduced cardiac function in mature hearts.In addition,transplantation of P7-CMs into infarcted hearts exhibited cardiac repair potential superior to P1-CMs.Collectively,our data uncover CM state transition as a key event in postnatal heart maturation,which not only provides insights into molecular foundations of heart maturation,but also opens an avenue for manipulation of cardiomyocyte fate in disease and regenerative medicine.Zheng Li Fang Yao Peng Yu Dandan Li Mingzhi Zhang Lin Mao Xiaomeng Shen Zongna Ren Li Wang Bingying Zhou 2022Protein & Cell2022,13,11:2

12Functional isolation,culture and cryopreservation of adult human primary cardiomyocytes显示文摘Cardiovascular diseases are the most common cause of death globally.Accurately modeling cardiac homeostasis,dysfunction,and drug response lies at the heart of cardiac research.Adult human primary cardiomyocytes(hPCMs)are a promising cellular model,but unstable isolation efficiency and quality,rapid cell death in culture,and unknown response to cryopreservation prevent them from becoming a reliable and flexible in vitro cardiac model.Combing the use of a reversible inhibitor of myosinⅡATPase,(-)-blebbistatin(Bleb),and multiple optimization steps of the isolation procedure,we achieved a 2.74-fold increase in cell viability over traditional methods,accompanied by better cellular morphology,minimally perturbed gene expression,intact electrophysiology,and normal neurohormonal signaling.Further optimization of culture conditions established a method that was capable of maintaining optimal cell viability,morphology,and mitochondrial respiration for at least 7 days.Most importantly,we successfully cryopreserved hPCMs,which were structurally,molecularly,and functionally intact after undergoing the freeze-thaw cycle.hPCMs demonstrated greater sensitivity towards a set of cardiotoxic drugs,compared to human-induced pluripotent stem cell-derived cardiomyocytes(hiPSC-CMs).Further dissection of cardiomyocyte drug response at both the population and single-cell transcriptomic level revealed that hPCM responses were more pronouncedly enriched in cardiac function,whereas hiPSC-CMs responses reflected cardiac development.Together,we established a full set of methodologies for the efficient isolation and prolonged maintenance of functional primary adult human cardiomyocytes in vitro,unlocking their potential as a cellular model for cardiovascular research,drug discovery,and safety pharmacology.Bingying Zhou Xun Shi Xiaoli Tang Quanyi Zhao Le Wang Fang Yao Yongfeng Hou Xianqiang Wang Wei Feng Liqing Wang Xiaogang Sun Li Wang Shengshou Hu 2022Signal Transduction and Targeted Therapy2022,7,8:1
