1A de novo Genome of a Chinese Radish Cultivar显示文摘Here, we report a high-quality draft genome of a Chinese radish(Raphanus sativus) cultivar. This draft contains 387.73 Mb of assembled scaffolds, 83.93% of the scaffolds were anchored onto nine pseudochromosomes and 95.09% of 43 240 protein-coding genes were functionally annotated. 184.75 Mb(47.65%) of repeat sequences was identified in the assembled genome. By comparative analyses of the radish genome against 10 other plant genomes, 2 275 genes in 780 gene families were found unique to R. sativus. This genome is a good reference for genomic study and of great value for genetic improvement of radish.ZHANG Xiaohui YUE Zhen MEI Shiyong QIU Yang YANG Xinhua CHEN Xiaohua CHENG Feng WU Zhangyan SUN Yuyan JING Yi LIU Bo SHEN Di WANG Haiping CUI Na DUAN Yundan WU Jian WANG Jinglei GAN Caixia WANG Jun WANG Xiaowu LI Xixiang 2015Horticultural Plant Journal2015,1,3:10
2SIDT1-dependent absorption in the stomach mediates host uptake of dietary and orally administered microRNAs显示文摘Dietary microRNAs have been shown to be absorbed by mammals and regulate host gene expression,but the absorption mechanism remains unknown.Here,we show that SIDT1 expressed on gastric pit cells in the stomach is required for the absorption of dietary microRNAs.SIDT1-deficient mice show reduced basal levels and impaired dynamic absorption of dietary microRNAs.Notably,we identified the stomach as the primary site for dietary microRNA absorption,which is dramatically attenuated in the stomachs of SIDT1-deficient mice.Mechanistic analyses revealed that the uptake of exogenous microRNAs by gastric pit cells is SIDT1 and low-pH dependent.Furthermore,oral administration of plant-derived miR2911 retards liver fibrosis,and this protective effect was abolished in SIDT1-deficient mice.Our findings reveal a major mechanism underlying the absorption of dietary microRNAs,uncover an unexpected role of the stomach and shed light on developing small RNA therapeutics by oral delivery.Qun Chen Fan Zhang Lei Dong Huimin Wu Jie Xu Hanqin Li Jin Wang Zhen Zhou Chunyan Liu Yanbo Wang Yuyan Liu Liangsheng Lu Chen Wang Minghui Liu Xi Chen Cheng Wang Chunni Zhang Dangsheng Li Ke Zen Fangyu Wang Qipeng Zhang Chen-Yu Zhang 2021Cell Research2021,31,3:10
3Research of optical rainfall sensor based on CCD linear array显示文摘Rainfall monitoring is one of the most important meteorological observation elements for the disaster weather. The maintenance of current tipping bucket rain gauge and weighing type rain gauge is a critical issue. The optical rainfall sensor based on CCD linear array is mainly studied in this paper. Because of the maintenance-free time and good adaptability,it can be widely used in the automatic rainfall monitoring in severe environment and have a good perspective in using.YANG Bifeng LIU Yuyan LU Ying WU Shangqian 2015Instrumentation2015,2,3:9

5LIN28 coordinately promotes nucleolar/ribosomal functions and represses the 2C-like transcriptional program in pluripotent stem cells显示文摘LIN28 is an RNA binding protein with important roles in early embryo development,stem cell differentiation/re-programming,tumorigenesis and metabolism.Previous studies have focused mainly on its role in the cytosol where it interacts with Let-7 microRNA precursors or mRNAs,and few have addressed LIN28's role within the nucleus.Here,we show that LIN28 displays dynamic temporal and spatial expression during murine embryo development.Maternal LIN28 expression drops upon exit from the 2-cell stage,and zygotic LIN28 protein is induced at the forming nucleolus during 4-cell to blas-tocyst stage development,to become dominantly expressed in the cytosol after implantation.In cultured pluripotent stem cells(PSCs),loss of LIN28 led to nucleolar stress and activation of a 2-cell/4-cell-like transcriptional program characterized by the expression of endogenous retrovirus genes.Mechanistically,LIN28 binds to small nucleolar RNAs and rRNA to maintain nucleolar integrity,and its loss leads to nucleolar phase separation defects,ribosomal stress and activation of P53 which in turn binds to and activates 2C transcription factor Dux.LIN28 also resides in a complex containing the nucleolar factor Nucleolin(NCL)and the transcrip-tional repressor TRIM28,and LIN28 loss leads to reduced occupancy of the NCL/TRIM28 complex on the Dux and rDNA loci,and thus de-repressed Dux and reduced rRNA expression.Lin28 knockout cells with nucleolar stress are more likely to assume a slowly cycling,translationally inert and anabolically inactive state,which is a part of previously unappreciated 2C-like transcriptional program.These findings elucidate novel roles for nucleolar LIN28 in PSCs,and a new mechanism linking 2C program and nucleolar functions in PSCs and early embryo development.Zhen Sun Hua Yu Jing Zhao Tianyu Tan Hongru Pan Yuqing Zhu Lang Chen Cheng Zhang Li Zhang Anhua Lei Yuyan Xu Xianju Bi Xin Huang Bo Gao Longfei Wang Cristina Correia Ming Chen Qiming Sun Yu Feng Li Shen Hao Wu Jianlong Wang Xiaohua Shen George Q.Daley Hu Li Jin Zhang 2022Protein & Cell2022,13,7:4
6Survival difference between EGFR Del19 and L858R mutant advanced non-small cell lung cancer patients receiving gefitinib:a propensity score matching analysis显示文摘Objective: Although superior clinical benefits of epidermal growth factor receptor(EGFR) tyrosine kinase inhibitors(TKIs) in the treatment of advanced non-small-cell lung cancer(NSCLC) had been reported,the survival difference between exon 19 deletion(Del19) and exon 21 Leu858 Arg substitution(L858 R) remains controversial.The purpose of this study is to investigate the differences in progression-free survival(PFS) and overall survival(OS) between different EGFR mutant subtypes among advanced NSCLC patients receiving gefitinib.Methods: There were 204 advanced NSCLC patients with EGFR mutations treated with gefitinib were enrolled in this retrospective cohort study.Patients were divided into the EGFR Del19 group and the L858 R mutated group according to their mutant subtype.Propensity score matching(PSM) was conducted by using a nearest-neighbor algorithm(1:1) to adjust for demographical and clinical covariates.Survival curves were constructed with the Kaplan-Meier method and compared by using the log-rank test.Results: The PFS in Del19 group was similar to that in the L858 R group [before PSM 8.6 vs.7.2 months,P=0.072; after PSM 7.3 vs.7.2 months,P=0.155].No differences were detected in OS between the L858 R and the Del19 group(before PSM 17.8 vs.13.1 months,P=0.253; after PSM 16.9 vs.13.1 months,P=0.339).The Del19 group was significantly younger compared with the L858 R mutation group in age(P=0.015).Conclusions: No significant difference was found in the PFS or OS between the Del19 and L858 R mutant NSCLC patients receiving gefitinib.The age gap might contribute to the survival differences between Del19 and L858 R groups.PSM is of important value to the elimination of potential bias.Minglei Zhuo Qiwen Zheng Jun Zhao Meina Wu Tongtong An Yuyan Wang Jianjie Li Shuhang Wang Jia Zhong Xue Yang Hanxiao Chen Bo Jia Zhi Dong Emei Gao JingjingWang Ziping Wang 2017Chinese Journal of Cancer Research2017,29,6:4
7A phase I study of nimotuzumab plus docetaxel in chemotherapy- refractory/resistant patients with advanced non-small-cell lung cancer显示文摘Background: To determine the safety and therapeutic efficacy of nimotuzumab(h-R3) combined with docetaxel in advanced non-small-cell lung cancer(NSCLC) patients who have failed to respond to prior first-line chemotherapy.Methods: In this single-center, open-label, dose-escalating phase I trial, patients with epidermal growth factor receptor(EGFR)-expressing stage IV NSCLC were treated with nimotuzumab plus docetaxel according to a dose escalation schedule. The safety and efficacy of the combination treatment were observed and analyzed.Results: There were 12 patients with EGFR-expressing stage IV NSCLC enrolled. The dose of nimotuzumab was escalated from 200 to 600 mg/week. The longest administration of study drug was 40 weeks at the 600 mg/week dose level. Grade III–IV toxicities included neutropenia and fatigue, and other toxicities included rash. Dose-limiting toxicity occurred with Grade 3 fatigue at the 200 mg dose level of nimotuzumab and Grade 4 neutropenia with pneumonia at the 600 mg dose level of nimotuzumab. No objective responses were observed, and stable disease was observed in eight patients(66.7%). The median progression-free survival(PFS) was 4.4 months in all patients, 1.3 months in patients with the EGFR mutation, and 4.4 months in those with wild type EGFR(EGFR WT). The median survival time(MST) was 21.1 months in all patients, 21.1 months in patients with EGFR mutation, and 26.4 months in patients with EGFR WT.Conclusions: Nimotuzumab and docetaxel combination therapy was found to be well tolerated and efficacious. Further study of nimotuzumab is warranted in advanced NSCLC patients.Jun Zhao Minglei Zhuo Zhijie Wang Jianchun Duan Yuyan Wang Shuhang Wang Tongtong An Meina Wu Jie Wang 2016Chinese Journal of Cancer Research2016,28,1:3
8Securities regulation and implicit penalties显示文摘The extant literature offers extensive support for the significant role played by institutions in financial markets,but implicit regulation and monitoring have yet to be examined.This study fills this void in the literature by employing unique Chinese datasets to explore the implicit regulation and penalties imposed by the Chinese government in regulating the initial public offering(IPO) market.Of particular interest are the economic consequences of underwriting IPO deals for client firms that violate regulatory rules in China's capital market.We provide evidence to show that the associated underwriters' reputations are impaired and their market share declines.We further explore whether such negative consequences result from a market disciplinary mechanism or a penalty imposed by the government.To analyze the possibility of a market disciplinary mechanism at work,we investigate(1) the market reaction to other client firms whose IPO deals were underwritten by underwriters associated with a violation at the time the violation was publicly disclosed and(2) the under-pricing of IPO deals undertaken by these underwriters after such disclosure.To analyze whether the government imposes an implicit penalty,we examine the application processing time for future IPO deals underwritten by the associated underwriters and find it to be significantly longer than for IPO deals underwritten by other underwriters.Overall,there is little evidence to suggest that the market penalizes underwriters for the rule-violating behavior of their client firms in China.Instead,the Chinese government implicitly penalizes them by imposing more stringent criteria on and lengthening the processing time of the IPO deals they subsequently underwrite.Donghua Chen Yuyan Guan Gang Zhao Feifei Wu 2011China Journal of Accounting Research2011,,Z1:2

10Low-depth whole genome sequencing reveals copy number variations associated with higher pathologic grading and more aggressive subtypes of lung non-mucinous adenocarcinoma显示文摘Objective:Histology grade,subtypes and TNM stage of lung adenocarcinomas are useful predictors of prognosis and survival.The aim of the study was to investigate the relationship between chromosomal instability,morphological subtypes and the grading system used in lung non-mucinous adenocarcinoma(LNMA).Methods:We developed a whole genome copy number variation(WGCNV)scoring system and applied next generation sequencing to evaluate CNVs present in 91 LNMA tumor samples.Results:Higher histological grades,aggressive subtypes and more advanced TNM staging were associated with an increased WGCNV score,particularly in CNV regions enriched for tumor suppressor genes and oncogenes.In addition,we demonstrate that 24-chromosome CNV profiling can be performed reliably from specific cell types(<100 cells)isolated by sample laser capture microdissection.Conclusions:Our findings suggest that the WGCNV scoring system we developed may have potential value as an adjunct test for predicting the prognosis of patients diagnosed with LNMA.Zheng Wang Lin Zhang Lei He Di Cui Chenglong Liu Liangyu Yin Min Zhang Lei Jiang Yuyan Gong Wang Wu Bi Liu Xiaoyu Li David S Cram Dongge Liu 2020Chinese Journal of Cancer Research2020,32,3:1
11Methylation status of DJ-1 in leukocyte DNA of Parkinson’s disease patients显示文摘Background:DJ-1 has been thought as a candidate biomarker for Parkinson’s disease(PD).It was found reduced in PD brains,CSF and saliva,although there were conflicting results.How DJ-1 expression may be regulated is not clear.Recently,blood-based DNA methylation represents a highly promising biomarker for PD by regulating the causative gene expression.Thus,in this study,we try to explore whether blood-based DNA methylation of DJ-1 could be used as a biomarker to differentiate PD patients from normal control(NC),and whether DNA methylation could regulate DJ-1 expression in a SH-SY5Y cell model.Methods:Forty PD patients and 40 NC were recruited in this study.DNA was extracted from peripheral blood leukocytes(PBLs).Methylation status of two CpG islands(CpG1 and CpG2)in promoter region of DJ-1 was explored by bisulfite specific PCR-based sequencing method.Methylation inhibitor 5-Aza-dC was used to treat SH-SY5Y cell line,DJ-1 level was detected in both mRNA and protein level.Results:CpG sites in these two CpG islands(CpG1 and CpG2)of DJ-1 were unmethylated in both PD and NC group.In SH-SY5Y cell model treated by methylation inhibitor,there was no significant change of DJ-1 expression in either mRNA level or protein level.Conclusions:Our results indicated that DNA methylation inhibitor didn’t alter DJ-1 gene expression in SH-SY5Y cell model,and DNA methylation of DJ-1 promoter region in PBLs level might not be an efficient biomarker for PD patients.Yuyan Tan Li Wu Dunhui Li Xiaoli Liu Jianqing Ding Shengdi Chen 2016Translational Neurodegeneration2016,5,1:1
12PIK3CA mutation in Chinese patients with lung squamous cell carcinoma显示文摘Objective: To investigate PIK3CA mutation in Chinese patients with lung squamous cell carcinoma (LSCC) and explore their relationship with clinicopathological profiles. Methods: Tumor samples from 123 cases of LSCC were included in this study. PIK3CA mutations in exon 9 and 20 were screened by pyrosequencing and confirmed by clone sequencing or amplification refractory mutation system (ARMS). Denaturing performance liquid chromatography (DHPLC) was employed for evaluation of EGFR mutation in exon 19, 21 and KRAS mutation. Results: PIK3CA mutations were found in 3 (2.4%) patients. The mutation type included E545K, E452Q and H1047R. Of these three patients, one coupled with EGFR mutation, and the other two coupled with PIK3CA amplification. All the three patients shared the same clinicopathologic characteristics: male, less than 60 years old, had smoke history, stage III and carried wild-type KRAS. Conclusions: The frequency of PIK3CA mutation is low in Chinese patients with LSCC. The mutational status of PIK3CA is not mutually exclusive to EGFR mutation.Jinglin Yu Hua Bai Zhijie Wang Zhigang Wei Xiaosheng Ding Jianchun Duan Lu Yang Meina Wu Yuyan Wang Jie Wang 2013Chinese Journal of Cancer Research2013,25,4:1

14Genome-wide identification of functional enhancers and their potential roles in pig breeding显示文摘Background:The pig is an economically important livestock species and is a widely applied large animal model in medical research.Enhancers are critical regulatory elements that have fundamental functions in evolution,development and disease.Genome-wide quantification of functional enhancers in the pig is needed.Results:We performed self-transcribing active regulatory region sequencing(STARR-seq)in the porcine kidney epithelial PK15 and testicular ST cell lines,and reliably identified 2576 functional enhancers.Most of these enhancers were located in repetitive sequences and were enriched within silent and lowly expressed genes.Enhancers poorly overlapped with chromatin accessibility regions and were highly enriched in chromatin with the repressive histone modification H3K9me3,which is different from predicted pig enhancers detected using ChIP-seq for H3K27ac or/and H3K4me1 modified histones.This suggests that most pig enhancers identified with STARR-seq are endogenously repressed at the chromatin level and may function during cell type-specific development or at specific developmental stages.Additionally,the PPP3CA gene is associated with the loin muscle area trait and the QKI gene is associated with alkaline phosphatase activity that may be regulated by distal functional enhancers.Conclusions:In summary,we generated the first functional enhancer map in PK15 and ST cells for the pig genome and highlight its potential roles in pig breeding.Yinqiao Wu Yuedong Zhang Hang Liu Yun Gao Yuyan Liu Ling Chen Lu Liu David M.Irwin Chunhui Hou Zhongyin Zhou Yaping Zhang 2022Journal of Animal Science and Biotechnology2022,13,6:1

16Effect of Wuda granule on gastrointestinal function recovery after laparoscopic intestinal resection:a randomized–controlled trial显示文摘Background Previous studies have suggested that the Wuda granule(WDG)could promote the recovery of gastrointestinal(GI)function after gynecologic abdominal surgery.This trial aimed to investigate the efficacy and safety of WDG in the rapid recovery of GI function in patients after laparoscopic intestinal resection in the setting of enhanced recovery after surgery(ERAS)-based perioperative care.Methods We performed a randomized,double-blind,placebo-controlled pilot trial.Thirty patients who met the inclusion criteria were randomly assigned to either the WDG group or the placebo group in a 1:1 ratio.The patients received WDG or placebo twice a day in addition to ERAS-based perioperative care,starting on post-operative Day 1 until Day 3.The primary outcomes were time to first bowel movement and time to first tolerance of solid food.The secondary outcomes were time to first flatus,length of hospital stay(LOS),and post-operative ileus-related morbidity.Adverse events were also recorded.Results There were no statistically significant differences in baseline characteristics between the two groups.The median time to first bowel movement was significantly decreased in the WDG group compared with the control group(27.6 vs 50.1 h;P<0.001),but the median times to first flatus(22.9 vs 25.1 h;P>0.05)and LOS(5.0 vs 5.0 days;P>0.05)were not statistically different.The occurrence rates of post-operative nausea,vomiting,abdominal distension,and abdominal pain were similar in the two groups.No adverse events occurred in any patients.Conclusions The addition of WDG to ERAS post-operative care after laparoscopic intestinal resection can safely promote the rapid recovery of GI function.Haiping Zeng Wei Wang Lixing Cao Yuyan Wu Wenwei Ouyang Dechang Diao Jin Wan Qicheng Chen Zhiqiang Chen 2022Gastroenterology Report2022,10,1:1

18A non-ACE2 competing human single-domain antibody confers broad neutralization against SARS-CoV-2 and circulating variants显示文摘The current COVID-19 pandemic has heavily burdened the global public health system and may keep simmering for years.The frequent emergence of immune escape variants have spurred the search for prophylactic vaccines and therapeutic antibodies that confer broad protection against SARS-CoV-2 variants.Here we show that the bivalency of an affinity maturated fully human singledomain antibody(n3113.1-Fc)exhibits exquisite neutralizing potency against SARS-CoV-2 pseudovirus,and confers effective prophylactic and therapeutic protection against authentic SARS-CoV-2 in the host cell receptor angiotensin-converting enzyme 2(ACE2)humanized mice.The crystal structure of n3113 in complex with the receptor-binding domain(RBD)of SARS-CoV-2,combined with the cryo-EM structures of n3113 and spike ecto-domain,reveals that n3113 binds to the side surface of up-state RBD with no competition with ACE2.The binding of n3113 to this novel epitope stabilizes spike in up-state conformations but inhibits SARS-CoV-2 S mediated membrane fusion,expanding our recognition of neutralization by antibodies against SARS-CoV-2.Binding assay and pseudovirus neutralization assay show no evasion of recently prevalent SARS-CoV-2 lineages,including Alpha(B.1.1.7),Beta(B.1.351),Gamma(P.1),and Delta(B.1.617.2)for n3113.1-Fc with Y58L mutation,demonstrating the potential of n3113.1-Fc(Y58L)as a promising candidate for clinical development to treat COVID-19.Zhenlin Yang Yulu Wang Yujia Jin Yuanfei Zhu Yanling Wu Cheng Li Yu Kong Wenping Song Xiaolong Tian Wuqiang Zhan Ailing Huang Shanshan Zhou Shuai Xia Xiaoxu Tian Chao Peng Cuicui Chen Yibing Shi Gaowei Hu Shujuan Du Yuyan Wang Youhua Xie Shibo Jiang Lu Lu Lei Sun Yuanlin Song Tianlei Ying 2021Signal Transduction and Targeted Therapy2021,6,12:1
