| 4 | Integrative single-cell analysis of transcriptome,DNA methylome and chromatin accessibility in mouse oocytes显示文摘Oocyte growth is a key step in forming mature eggs that are ready to be fertilized.The states and modifications of chromatin represent critical sources of information for this process.However,the dynamics and interrelations of these chromatin characteristics remain elusive.In this study,we developed an improved scCOOL-seq technique (iscCOOL-seq),which is a multiomics,single-cell and single-base resolution method with high mapping rates,and explored the chromatin accessibility landscape and its relationship to DNA methylation in growing mouse oocytes.The most dramatic change in chromatin accessibility occurs during oocyte growth initiation,accompanied with prominent transcriptome alterations and an elevated variation in DNA methylation levels among individual oocytes.Unlike CpG islands (CGIs),partially methylated domains (PMDs)are associated with a low density of nucleosome-depleted regions (NDRs)during the whole maturation period.Surprisingly,highly expressed genes are usually associated with NDRs at their transcriptional end sites (TESs).In addition,genes with de novo methylated gene bodies during oocyte maturation are already open at their promoters before oocyte growth initiation.Furthermore,epigenetic and transcription factors that might be involved in oocyte maturation are identified.Our work paves the way for dissecting the complex, yet highly coordinated,epigenetic alterations during mouse oocyte growth and the establishment of totipotency. | Chan Gu Shanling Liu Qihong Wu Lin Zhang Fan Guo | 2019 | Cell Research2019,29,2: | 14 |

| 9 | Indoleamine 2,3-dioxygenase (IDO) is essential for dendritic cell activation and chemotactic responsiveness to chemokines显示文摘Indoleamine 2, 3-dioxygenase (IDO) is a rate-limiting enzyme for the tryptophan catabolism. In human and murine cells, IDO inhibits antigen-specific T cell proliferation in vitro and suppresses T cell responses to fetal alloantigens during murine pregnancy. In mice, IDO expression is an inducible feature of specific subsets of dendritic cells (DCs), and is important for T cell regulatory properties. However, the effect of IDO and tryptophan deprivation on DC func- tions remains unknown. We report here that when tryptophan utilization was prevented by a pharmacological inhibitor of IDO, 1-methyl tryptophan (1MT), DC activation induced by pathogenic stimulus lipopolysaccharide (LPS) or inflam- matory cytokine TNF-α was inhibited both phenotypically and functionally. Such an effect was less remarkable when DC was stimulated by a physiological stimulus, CD40 ligand. Tryptophan deprivation during DC activation also regu- lated the expression of CCR5 and CXCR4, as well as DC responsiveness to chemokines. These results suggest that tryptophan usage in the microenvironment is essential for DC maturation, and may also play a role in the regulation of DC migratory behaviors. | Shih Ling HWANG Nancy Pei-Yee CHUNG Jacqueline Kwai-Yi CHAN Chen-Lung Steve LIN | 2005 | Cell Research2005,15,3: | 11 |
| 10 | Reduction of the ages at diagnosis and operation of biliary atresia in Taiwan: A 15-year population-based cohort study显示文摘AIM: To describe the ages at diagnosis and operation of biliary atresia(BA) and its incidence over a 15-year period in Taiwan.METHODS: This was a population-based cohort study. BA cases were identified from the Taiwan National Health Insurance Research Database based on the International Classification of Diseases,Ninth Revision(ICD-9) code of BA 751.61 plus Kasai operation(ICD-9 procedure code 51.37) or liver transplantation(LT,ICD-9 procedure code 50.5). The patients' characteristics including sex,age at diagnosis,age at receiving Kasai operation and age at receiving LT were compared among three birth cohorts:(1) 1997 to 2001;(2) 2002 to 2006; and(3) 2007 to 2011.RESULTS: There were a total of 540 BA cases(275 females) with an incidence of 1.62 per 10000 live births. No seasonality of BA was noted. The mean ages at diagnosis of three cohorts were 57.9,55.6 and 52.6 d.A linear regression model demonstrated a decreasing trend of the mean age at diagnosis(1.27 d per year). The proportion of BA cases that received the Kasai operation within 60 d of age increased from 76% to 81%. A total of 189(35%) BA patients underwent LT. The mean age at LT was reduced from 3-year-old to 1-year-old. The rates of LT were 25.6% and 32.3% in patients who received the Kasai operation within 60 d or after 60 d of age,respectively. All patients who did not undergo a Kasai operation eventually required LT.CONCLUSION: The ages at diagnosis and operation in BA cases have decreased over time. Kasai operation performed at younger age reduces the need for LT. The incidence of BA in Taiwan fluctuates,but without certain trend. | Jen-Shyang Lin Solomon Chih-Cheng Chen Chin-Li Lu Hung-Chang Lee Chun-Yan Yeung Wai-Tao Chan | 2015 | World Journal of Gastroenterology2015,21,46: | 10 |

| 12 | Effectiveness of Traditional Chinese Medicine on chemo-radiotherapy induced leukaemia in patients with lung cancer:a Meta-analysis显示文摘OBJECTIVE: To assess the curative effect of Traditional Chinese Medicine(TCM) on leukopenia induced by chemo-radiotherapy in patients with lung cancer.METHODS: A comprehensive electronic search in Medline, Embase, the Cochrane Libary database,China National Knowledge Infrastructure Database(CNKI) and Wanfang Database was conducted up to July 2017. Random-effects model was used to estimate the standardized mean differences(SMDs)with 95% confidence intervals(CIs). Eleven studies with a total of 957 patients were included in this meta-analysis.RESULTS: The effectiveness in TCM group was higher than control group [RR = 1.60, 95% CI(1.38, 1.85),P < 0.000 01]. Compare with Western Medicinegroup, the effectiveness has no significant difference [RR = 0.96, 95% CI(0.82, 1.12), P = 0.57]. The ineffective rate in test group was lower than the control group [RR = 0.30, 95% CI(0.21, 0.42), P < 0.00001].CONCLUSION: By meta-regression it was suggested that TCM has curative effect on leukopenia induced by chemo-radiotherapy in patients with lung cancer, but by the influence of number and quality of researches, publication bias, more evidence from high quality studies, and larger cohorts for observational trials are needed. | Li Yu Xiong Chan Qin Erqi Li Lin Zhuang Guangtong Yu Zheng | 2018 | Journal of Traditional Chinese Medicine2018,38,5: | 9 |

| 14 | Clinical utility of Epstein-Barr virus DNA and other liquid biopsy markers in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is a malignant epithelial tumor ubiquitously associated with the Epstein-Barr virus(EBV),which is highly prevalent in South China,Southeast Asia,and North Africa.Despite being a highly radio-sensitive and treatable cancer,a majority of NPC patients are diagnosed in their advanced stage,and locoregional and distant relapses following definitive treatment contribute largely to cancer-specific mortality among these patients.Given that EBV-driven NPC is the predominant variant seen in endemic regions,various EBV detection methods have been developed and are utilized in screening,prognostication,and post-treatment surveillance of NPC patients.While the Immunoglobulin A(IgA)serology assay is the most extensively studied EBV detection method,the detection of plasma EBV DNA released during replication or cellular apoptosis has shown superior outcomes in endemic population screening,prognostication,and detection of distant relapse.Furthermore,there is emerging evidence on the use of circulating tumor cells,microRNAs,DNA hypermethylation,and combination assays in various clinical scenarios.Herein,this paper provides a comprehensive overview of the relevant studies using various EBV detection techniques in the management of NPC.Specifically,the recent advances,clinical evidence,and challenges associated with the clinical application of EBV liquid biopsies in population screening,prognostication,and surveillance of NPC are presented. | Rong Tan Sean Kean Ann Phua Yoke Lim Soong Lynette Lin Ean Oon Kian Sing Chan Sasidharan Swarnalatha Lucky Jamie Mong Min Han Tan Chwee Ming Lim | 2020 | Cancer Communications2020,40,11: | 8 |
| 15 | Deformation behavior of Zr-based bulk metallic glass and composite in the supercooled liquid region显示文摘A Zr-based bulk metallic glass (BMG) with a composition of (Zr75Cu25)78.5Ta4Ni10Al7.5 and a bulk metallic glass matrix composite (BMGC) with a composition of (Zr75Cu25)74.5Ta8Ni10Al7.5 have been prepared by copper-mold casting. The compres-sive deformation behavior of the BMG and BMGC was investigated in the super-cooled region at different temperatures and various strain rates ranging from 8×10-4s-1 to 8×10-2s-1. It was found that both the strain rate and test temperature signifi-cantly affect the deformation behavior of the two alloys. The deformation follows Newtonian flow at low strain rates but non-Newtonian flow at high strain rates. The deformation mechanism for the two kinds of alloys was discussed in terms of the transition state theory. | CHEN Qi LIU Lin CHAN K.C. | 2008 | Science China(Physics,Mechanics & Astronomy)2008,51,4: | 8 |

| 17 | Progressive loss of striatal dopamine terminals in MPTP-induced acute parkinsonism in cynomolgus monkeys using vesicular monoamine transporter type 2 PET imaging([^(18)F]AV-133)显示文摘The 1-methyl-4-phenyl-1,2,3,4-tetrahydropyridine(MPTP)-induced parkinsonism model, particularly in non-human primates, remains the gold-standard for studying the pathogenesis and assessing novel therapies for Parkinson's disease. However, whether the loss of dopaminergic neurons in this model is progressive remains controversial, mostly due to the lack of objective in vivo assessment of changes in the integrity of these neurons. In the present study, parkinsonism was induced in cynomolgus monkeys by intravenous administration of MPTP(0.2 mg/kg) for 15 days; stable parkinsonism developed over 90 days, when the symptoms were stable. Noninvasive positron emission tomographic neuroimaging of vesicular monoamine transporter 2 with 9-[18F]fluoropropyl-(+)-dihydrotetrabenazine([18F]AV-133) was used before, and 15 and 90 days after the beginning of acute MPTP treatment. The imaging showed evident progressive loss of striatal uptake of [18F]AV-133. The dopaminergic denervation severity had a significant linear correlation with the clinical rating scores and the bradykinesia subscores. Thesefindings demonstrated that [18F]AV-133 PET imaging is a useful tool to noninvasively evaluate the evolution of monoaminergic terminal loss in a monkey model of MPTP-induced parkinsonism. | Yajing Liu Feng Yue Rongping Tang Guoxian Tao Xiaomei Pan Lin Zhu Hank F.Kung Piu Chan | 2014 | Neuroscience Bulletin2014,30,3: | 6 |
