| 1 | Molecular immune pathogenesis and diagnosis of COVID-19显示文摘Coronavirus disease 2019(COVID-19)is a kind of viral pneumonia which is caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).The emergence of SARS-CoV-2 has been marked as the third introduction of a highly pathogenic coronavirus into the human population after the severe acute respiratory syndrome coronavirus(SARS-CoV)and the Middle East respiratory syndrome coro-navirus(MERS-CoV)in the twenty-first century.In this minireview,we provide a brief introduction of the general features of SARS-CoV-2 and discuss current knowledge of molecular immune pathogenesis,diagnosis and treatment of COVID-19 on the base of the present understanding of SARS-CoV and MERS-CoV infections,which may be helpful in offering novel insights and potential therapeutic targets for combating the SARS-CoV-2 infection. | Xiaowei Li Manman Geng Yizhao Peng Liesu Meng Shemin Lu | 2020 | Journal of Pharmaceutical Analysis2020，10，2： | 31 |
| 2 | Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype. | Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu | 2021 | Cell Research2021，31，3： | 9 |
| 3 | A single-cell transcriptome of mesenchymal stromal cells to fabricate bioactive hydroxyapatite materials for bone regeneration显示文摘The osteogenic microenvironment of bone-repairing materials plays a key role in accelerating bone regeneration but remains incompletely defined,which significantly limits the application of such bioactive materials.Here,the transcriptional landscapes of different osteogenic microenvironments,including three-dimensional(3D)hydroxyapatite(HA)scaffolds and osteogenic medium(OM),for mesenchymal stromal cells(MSCs)in vitro were mapped at single-cell resolution.Our findings suggested that an osteogenic process reminiscent of endochondral ossification occurred in HA scaffolds through sequential activation of osteogenic-related signaling pathways,along with inflammation and angiogenesis,but inhibition of adipogenesis and fibrosis.Moreover,we revealed the mechanism during OM-mediated osteogenesis involves the ZBTB16 and WNT signaling pathways.Heterogeneity of MSCs was also demonstrated.In vitro ossification of LRRC75A+MSCs was shown to have better utilization of WNT-related ossification process,and PCDH10+MSCs with superiority in hydroxyapatite-related osteogenic process.These findings provided further understanding of the cellular activity modulated by OM conditions and HA scaffolds,providing new insights for the improvement of osteogenic biomaterials.This atlas provides a blueprint for research on MSC heterogeneity and the osteogenic microenvironment of HA scaffolds and a database reference for the application of bioactive materials for bone regeneration. | Peng Guo Xizhe Liu Penghui Zhang Zhongyuan He Zhen Li Mauro Alini RGeoff Richards Sibylle Grad Martin J.Stoddart Guangqian Zhou Xuenong Zou Danny Chan Wei Tian Dafu Chen Manman Gao Zhiyu Zhou Shaoyu Liu | 2022 | Bioactive Materials2022，7，3： | 3 |

| 5 | Effects of drip and flood irrigation on carbon dioxide exchange and crop growth in the maize ecosystem in the Hetao Irrigation District,China显示文摘Drip irrigation and flood irrigation are major irrigation methods for maize crops in the Hetao Irrigation District,Inner Mongolia Autonomous Region,China.This research delves into the effects of these irrigation methods on carbon dioxide(CO_(2))exchange and crop growth in this region.The experimental site was divided into drip and flood irrigation zones.The irrigation schedules of this study aligned with the local commonly used irrigation schedule.We employed a developed chamber system to measure the diurnal CO_(2)exchange of maize plants during various growth stages under both drip and flood irrigation methods.From May to September in 2020 and 2021,two sets of repeated experiments were conducted.In each experiment,a total of nine measurements of CO_(2)exchange were performed to obtain carbon exchange data at different growth stages of maize crop.During each CO_(2)exchange measurement event,CO_(2)flux data were collected every two hours over a day-long period to capture the diurnal variations in CO_(2)exchange.During each CO_(2)exchange measurement event,the biological parameters(aboveground biomass and crop growth rate)of maize and environmental parameters(including air humidity,air temperature,precipitation,soil water content,and photosynthetically active radiation)were measured.The results indicated a V-shaped trend in net ecosystem CO_(2)exchange in daytime,reducing slowly at night,while the net assimilation rate(net primary productivity)exhibited a contrasting trend.Notably,compared with flood irrigation,drip irrigation demonstrated significantly higher average daily soil CO_(2)emission and greater average daily CO_(2)absorption by maize plants.Consequently,within the maize ecosystem,drip irrigation appeared more conducive to absorbing atmospheric CO_(2).Furthermore,drip irrigation demonstrated a faster crop growth rate and increased aboveground biomass compared with flood irrigation.A strong linear relationship existed between leaf area index and light utilization efficiency,irrespective of the irrigation method.Notably,drip irrigation displayed superior light use efficiency compared with flood irrigation.The final yield results corroborated these findings,indicating that drip irrigation yielded higher harvest index and overall yield than flood irrigation.The results of this study provide a basis for the selection of optimal irrigation methods commonly used in the Hetao Irrigation District.This research also serves as a reference for future irrigation studies that consider measurements of both carbon emissions and yield simultaneously. | LI Chaoqun HAN Wenting PENG Manman | 2024 | Journal of Arid Land2024，16，2： | 0 |
| 6 | LncFASA promotes cancer ferroptosis via modulating PRDX1 phase separation显示文摘Ferroptosis, a unique type of non-apoptotic cell death resulting from iron-dependent lipid peroxidation, has a potential physiological function in tumor suppression, but its underlying mechanisms have not been fully elucidated. Here, we report that the long non-coding RNA(lncRNA) LncFASA increases the susceptibility of triple-negative breast cancer(TNBC) to ferroptosis. As a tumor suppressor, LncFASA drives the formation of droplets containing peroxiredoxin1(PRDX1), a member of the peroxidase family, resulting in the accumulation of lipid peroxidation via the SLC7A11-GPX4 axis. Mechanistically, LncFASA directly binds to the Ahpc-TSA domain of PRDX1, inhibiting its peroxidase activity by driving liquid-liquid phase separation, which disrupts intracellular ROS homeostasis. Notably, high LncFASA expression indicates favorable overall survival in individuals with breast cancer, and LncFASA impairs the growth of breast xenograft tumors by modulating ferroptosis. Together, our findings illustrate the crucial role of this lncRNA in ferroptosis-mediated cancer development and provide new insights into therapeutic strategies for breast cancer. | Xiao Fan Fangzhou Liu Xiang Wang Ying Wang Yu Chen Chengyu Shi Xinwan Su Manman Tan Qingfeng Yan Jinrong Peng Jianzhong Shao Yan Xiong Aifu Lin | 2024 | Science China(Life Sciences)2024，67，3： | 0 |
