1Breast cancer development and progression:Risk factors,cancer stem cells,signaling pathways,genomics,and molecular pathogenesis显示文摘As the most commonly occurring cancer in women worldwide,breast cancer poses a formidable public health challenge on a global scale.Breast cancer consists of a group of biologically and molecularly heterogeneous diseases originated from the breast.While the risk factors associated with this cancer varies with respect to other cancers,genetic predisposition,most notably mutations in BRCA1 or BRCA2 gene,is an important causative factor for this malignancy.Breast cancers can begin in different areas of the breast,such as the ducts,the lobules,or the tissue in between.Within the large group of diverse breast carcinomas,there are various denoted types of breast cancer based on their invasiveness relative to the primary tumor sites.It is important to distinguish between the various subtypes because they have different prognoses and treatment implications.As there are remarkable parallels between normal development and breast cancer progression at the molecular level,it has been postulated that breast cancer may be derived from mammary cancer stem cells.Normal breast development and mammary stem cells are regulated by several signaling pathways,such as estrogen receptors(ERs),HER2,and Wnt/b-catenin signaling pathways,which control stem cell proliferation,cell death,cell differentiation,and cell motility.Furthermore,emerging evidence indicates that epigenetic regulations and noncoding RNAs may play important roles in breast cancer development and may contribute to the heterogeneity and metastatic aspects of breast cancer,especially for triple-negative breast cancer.This review provides a comprehensive survey of the molecular,cellular and genetic aspects of breast cancer.Yixiao Feng Mia Spezia Shifeng Huang Chengfu Yuan Zongyue Zeng Linghuan Zhang Xiaojuan Ji Wei Liu Bo Huang Wenping Luo Bo Liu Yan Lei Scott Du Akhila Vuppalapati Hue H.Luu Rex C.Haydon Tong-Chuan He Guosheng Ren 2018Genes & Diseases2018,5,2:24
2A Strigolactone Biosynthesis Gene Contributed to the Green Revolution in Rice显示文摘Plant architecture is a complex agronomic trait and a major factor of crop yield,which is affected by several important hormones.Strigolactones(SLs)are identified as a new class hormoneinhibiting branching in many plant species and have been shown to be involved in various developmental processes.Genetical and chemical modulation of the SL pathway is recognized as a promising approach to modify plant architecture.However,whether and how the genes involved in the SL pathway could be utilized in breeding still remain elusive.Here,we demonstrate that a partial loss-of-function allele of the SL biosynthesis gene,HIGH TILLERING AND DWARF 1/DWARF17(HTD1/D17),which encodes CAROTENOID CLEAVAGE DIOXYGENASE 7(CCD7),increases tiller number and improves grain yield in rice.We found that the HTD1 gene had been widely utilized and co-selected with Semidwarf 1(SD1),both contributing to the improvement of plant architecture in modern rice varieties since the Green Revolution in the 1960s.Understanding how phytohormone pathway genes regulate plant architecture and how they have been utilized and selected in breeding will lay the foundation for developing the rational approaches toward improving crop yield.Yuexing Wang Lianguang Shang Hong Yu Longjun Zeng Jiang Hu Shen Ni Yuchun Rao Sanfeng Li Jinfang Chu Xiangbing Meng Lei Wang Ping Hu Jijun Yan Shujing Kang Minghao Qu Hai Lin Tao Wang Quan Wang Xingming Hu Hongqi Chen Bing Wang Zhenyu Gao Longbiao Guo Dali Zeng Xudong Zhu Guosheng Xiong Jiayang Li Qian Qian 2020Molecular Plant2020,13,6:23
3MONOCULM 3,an Ortholog of WUSCHEL in Rice,Is Required for Tiller Bud Formation显示文摘WUSCHEL(WUS)plays an essential role for the maintenance of meristem activity in dicots,but its function is still elusive in monocots.We isolated a new monoculm mutant,monoculm 3(moc3),in which a point mutation causes the premature termination of rice O.sativa WUS(Os WUS).Morphological observation revealed that the formation of tiller buds was disrupted in moc3.MOC3 was localized in the nuclear and could interact with TOPLESS-RELATED PROTEINS(TPRs).The expression of MOC3 was induced by cytokinins and defection of MOC3 affected the expression of several two-component cytokinin response regulators,Os RRs and ORRs.Our results suggest that MOC3 is required for the formation of axillary buds and has a complex relationship with cytokinins.Zefu Lu Gaoneng Shao Jinsong Xiong Yongqing Jiao Jing Wang Guifu Liu Xiangbing Meng Yan Liang Guosheng Xiong Yonghong Wang Jiayang Li 2015Journal of Genetics and Genomics2015,42,2:17
4OsBRXL4 Regulates Shoot Gravitropism and Rice Tiller Angle through Affecting LAZY1 Nuclear Localization显示文摘Rice tiller angle is a key agronomic trait that contributes to ideal plant architecture and grain production.LAZY1 (LA1) was previously shown to control tiller angle via affecting shoot gravitropism,but the underlying molecular mechanism remains largely unknown.In this study,we identified an LA1-interacting protein named Brevis Radix Like 4 (OsBRXL4).We showed that the interaction between OsBRXL4 and LA1 occurs at the plasma membrane and that their interaction determines nuclear localization of LA1.We found that nuclear localization of LA1 is essential for its function,which is different from AtLA1,its Arabidopsis ortho.log.Overexpression of OsBRXL4 leads to a prostrate growth phenotype,whereas OsBRXLs RNAi plants,in which the expression levels of OsBRXLI,OsBRXL4,and OsBRXL5 were decreased,display a compact phenotype.Further genetic analysis also supported that OsBRXL4 controls rice tiller angle by affecting nuclear localization of LA1.Consistently,we demonstrated that OsBRXL4 regulates the shoot gravitropism through affecting polar auxin transport as did LA1.Taken together,our study not only identifies OsBRXL4 as a regulatory component of rice tiller angle but also provides new insights into genetic regulation of rice plant architecture.Zhen Li Yan Liang Yundong Yuan Lei Wang Xiangbing Meng Guosheng Xiong Jie Zhou Yueyue Cai Ningpei Han Lekai Hua Guifu Liu Jiayang Li Yonghong Wang 2019Molecular Plant2019,12,8:12
5Identification and functional analysis of the MOC1 interacting protein 1显示文摘Rice tillering is one of the most important agronomic traits that determine grain yields.Our previous study has demonstrated that the MONOCULM1 (MOC1) gene is a key component that controls the formation of rice tiller buds.To further elucidate the molecular mechanism of MOC1 involved in the regulation of rice tillering,we performed a yeast-two-hybrid screening to identify MOC1 interacting proteins (MIPs).Here we reported that MIP1 interacted with MOC1 both in vitro and in vivo.The overexpression of MIP1 resulted in enhanced tillering and reduced plant height.In-depth characterization of the context of MIP1 and MOC1 would further our understanding of molecular regulatory mechanisms of rice tillering.Fengli Sun Weiping Zhang Guosheng Xiong Meixian Yan Qian Qian Jiayang Li Yonghong Wang 2010Journal of Genetics and Genomics2010,37,1:9

7Geochronology, Geochemistry, and Hf Isotopic Compositions of Monzogranites and Mafic-Ultramafic Complexes in the Maxingdawannan Area, Eastern Kunlun Orogen, Western China: Implications for Magma Sources, Geodynamic Setting, and Petrogenesis显示文摘This paper presents zircon U-Pb-Hf isotopic compositions and whole-rock geochemical data for monzogranites and mafic-ultramafic complexes of the Maxingdawannan area in the western end of the east Kunlun orogenic belt, western China. The data are used to determine the ages, petrogenesis, magma sources, and geodynamic setting of the studied rocks. U-Pb zircon dating indicates that monzogranites and gabbros of the complexes were emplaced at 399 and 397 Ma, respectively. The monzogranites are shoshonitic, with high SiO2, Al2 O3 and total-alkali contents, and low TFeO, MgO, TiO2 and P2 O5 contents. The mafic-ultramafic complexes are characterized by low Si O2 contents. The monzogranites display enrichment in light rare-earth elements(LREE) and large-ion lithophile elements(LILE), depletion in heavy REEs(HREE) and high-field-strength elements(HFSE), and negative Eu anomalies(Eu/Eu*=0.36–0.48). The mafic-ultramafic complexes are also enriched in LREEs and LILEs, and depleted in HREEs and HFSEs, with weak Eu anomalies(Eu/Eu*=0.84–1.16). Zircon εHf(t) values for the monzogranites and mafic-ultramafic complexes range from-6.68 to 1.11 and-1.81 to 6.29, with zircon model ages of 1 812–1 319 Ma(TDM2) and 1 087–769 Ma(TDM1), respectively. Hf isotopic data indicate that primary magmas of the monzogranites are originated from partial melting of ancient lower crust during the Paleo-Mesoproterozoic, with a juvenile-crust component. Primitive magmas of the mafic-ultramafic complexes are likely originated from a depleted-mantle source modified by slab-derived fluids and contaminated by crustal components. Geochemical data and the geological setting indicate that Devonian intrusions in the Maxingdawannan area are related to northward subduction of the ProtoTethys oceanic lithosphere.Jiaming Yan Guosheng Sun Fengyue Sun Liang Li Haoran Li Zhenhua Gao Lei Hua Zhengping Yan 2019Journal of Earth Science2019,30,2:6
8Reverse atom transfer radical polymerization of methyl methacrylate initiated by AIBN/FeCl_3/isophthalic acid system显示文摘The reverse ATRP of MMA using AIBN/FeCl3/ isophthalic acid as the initiating system was successfully performed. The new initiating system can be used to synthesize PMMA with high molecular weight and narrow polydis-persity index. The polymerization shows ’living’/controlled characteristics. Compared with other initiating system used in reverse ATRP, the easy availability and non-toxicity of isophthalic acid make it very attractive.ZHANG Guosheng, ZHU Shenmin & YAN DeyueSchool of Chemistry and Chemical Technology, Shanghai Jiao Tong University, Shanghai 200240, China 2001Chinese Science Bulletin2001,46,13:3
9Identification and characterization of Mini1, a gene regulating rice shoot development显示文摘The aerial parts of higher plants are generated from the shoot apical meristem(SAM). In this study, we isolated a small rice(Oryza sativa L.) mutant that showed premature termination of shoot development and was named mini rice 1(mini1). The mutant was first isolated from a japonica cultivar Zhonghua11(ZH11) subjected to ethyl methanesulfonate(EMS)treatment. With bulked segregant analysis(BSA) and map-based cloning method, Mini1 gene was finally fine-mapped to an interval of 48.6 kb on chromosome 9. Sequence analyses revealed a single base substitution from G to A was found in the region, which resulted in an amino acid change from Gly to Asp.The candidate gene Os09g0363900 was predicted to encode a putative adhesion of calyx edges protein ACE(putative HOTHEAD precursor) and genetic complementation experiment confirmed the identity of Mini1. Os09g0363900 contains glucose-methanol-choline(GMC) oxidoreductase and NAD(P)-binding Rossmann-like domain, and exhibits high similarity to Arabidopsis HOTHEAD(HTH). Expression analysis indicated Mini1 was highly expressed in young shoots but lowly in roots and the expression level of most genes involved in auxin biosynthesis and signal transduction were reduced in mutant.We conclude that Mini1 plays an important role in maintaining SAM activity and promoting shoot development in rice.Yunxia Fang Jiang Hu Jie Xu Haiping Yu Zhenyuan Shi Guosheng Xiong Li Zhu Dali Zeng Guangheng Zhang Zhenyu Gao Guojun Dong Meixian Yan Longbiao Guo Yonghong Wang Qian Qian 2015Journal of Integrative Plant Biology2015,57,2:3
10Low phosphorus promotes NSP1–NSP2 heterodimerization to enhance strigolactone biosynthesis and regulate shoot and root architecture in rice显示文摘Phosphorus is an essential macronutrient for plant development and metabolism,and plants have evolved ingenious mechanisms to overcome phosphate(Pi)starvation.However,the molecular mechanisms underlying the regulation of shoot and root architecture by low phosphorus conditions and the coordinated utilization of Pi and nitrogen remain largely unclear.Here,we show that Nodulation Signaling Pathway 1(NSP1)and NSP2 regulate rice tiller number by promoting the biosynthesis of strigolactones(SLs),a class of phytohormones with fundamental effects on plant architecture and environmental responses.We found that NSP1 and NSP2 are induced by Oryza sativa PHOSPHATE STARVATION RESPONSE2(OsPHR2)in response to low-Pi stress and form a complex to directly bind the promoters of SL biosynthesis genes,thus markedly increasing SL biosynthesis in rice.Interestingly,the NSP1/2–SL signaling module represses the expression of CROWN ROOTLESS 1(CRL1),a newly identified early SL-responsive gene in roots,to restrain lateral root density under Pi deficiency.We also demonstrated that GR24^(4DO) treatment under normal conditions inhibits the expression of OsNRTs and OsAMTs to suppress nitrogen absorption but enhances the expression of OsPTs to promote Pi absorption,thus facilitating the balance between nitrogen and phosphorus uptake in rice.Importantly,we found that NSP1p:NSP1 and NSP2p:NSP2 transgenic plants show improved agronomic traits and grain yield under low-and medium-phosphorus conditions.Taken together,these results revealed a novel regulatory mechanism of SL biosynthesis and signaling in response to Pi starvation,providing genetic resources for improving plant architecture and nutrient-use efficiency in low-Pi environments.Kun Yuan Hao Zhang Chaoji Yu Nan Luo Jijun Yan Shuang Zheng Qingliang Hu Dahan Zhang Liquan Kou Xiangbing Meng Yanhui Jing Mingjiang Chen Xinwei Ban Zongyun Yan Zefu Lu Jian Wu Yu Zhao Yan Liang Yonghong Wang Guosheng Xiong Jinfang Chu Ertao Wang Jiayang Li Bing Wang 2023Molecular Plant2023,16,11:2

16Recent advances based on Mg anodes and their interfacial modulation in Mg batteries显示文摘Magnesium(Mg)batteries(MBs),as post-lithium-ion batteries,have received great attention in recent years due to their advantages of high energy density,low cost,and safety insurance.However,the formation of passivation layers on the surface of Mg metal anode and the poor compatibility between Mg metal and conventional electrolytes during charge-discharge cycles seriously affect the performance of MBs.The great possibility of generating Mg dendrites has also caused controversy among researchers.Moreover,the regulation of Mg deposition and the enhancement of battery cycle stability is largely limited by interfacial stability between Mg metal anode and electrolyte.In this review,recent advances in interfacial science and engineering of MBs are summarized and discussed.Special attention is given to interfacial chemistry including passivation layer formation,incompatibilities,ion transport,and dendrite growth.Strategies for building stable electrode/interfaces,such as anode designing and electrolyte modification,construction of artificial solid electrolyte interphase(SEI)layers,and development of solid-state electrolytes to improve interfacial contacts and inhibit Mg dendrite and passivation layer formation,are reviewed.Innovative approaches,representative examples,and challenges in developing high-performance anodes are described in detail.Based on the review of these strategies,reference is provided for future research to improve the performance of MBs,especially in terms of interface and anode design.Fanfan Liu Guoqin Cao Jinjin Ban Honghong Lei Yan Zhang Guosheng Shao Aiguo Zhou Li zhen Fan Junhua Hu 2022Journal of Magnesium and Alloys2022,10,10:1
