| 1 | Mapping a mammalian adult adrenal gland hierarchy across species by microwell-seq显示文摘Recently,single-cell RNA-seq technologies have been rapidly updated,leading to a revolution in biology.We previously developed Microwell-seq,a cost-effective and high-throughput single cell RNA sequencing(scRNA-seq)method with a very simple device.Most cDNA libraries are sequenced using an expensive Illumina platform.Here,we present the first report showing combined Microwell-seq and BGI MGISEQ2000,a less expensive sequencing platform,to profile the whole transcriptome of 11,883 individual mouse adult adrenal gland cells and identify 18 transcriptionally distinct clusters.Moreover,we performed a single-cell comparative analysis of human and mouse adult adrenal glands to reveal the conserved genetic networks in these mammalian systems.These results provide new insights into the sophisticated adrenal gland hierarchy and provide a benchmark,low-cost strategy for highthroughput single-cell RNA study. | Shujing Lai Lifeng Ma Weigao E Fang Ye Haide Chen Xiaoping Han Guoji Guo | 2020 | Cell Regeneration2020，9，1： | 2 |

| 3 | Effects of Dispersive Agent and Alumina Micropowder on Workability of Al_2O_3-MgO Castables for Steel Ladles显示文摘This work aims at enhancing the workability of Al2 O3-Mg O castables. Al2 O3-Mg O castables were prepared using tabular alumina particles( 5-3,3-1,≤1 mm),tabular alumina fines( ≤0. 088 mm),fused magnesia( ≤1 mm),reactive alumina micropowder( PFR40,PBR,and CL) and calcined alumina micropowder( AC34 B5 and CT) as the main starting materials,calcium aluminate cement( Secar71) as the binder,and polycarboxylic acid water reducer WS,FS,and AD as the dispersive agent,respectively. Effects of three dispersive agents addition( 0. 4 mass% WS,0. 2 mass% FS and 1 mass% AD),two kinds of reactive alumina micropowder addition( PFR40 and PBR),composite alumina micropowder addition( PFR40-AC34 B5 and CL-CT,the mass ratio from 9/0 to 3/6)on the flow value,apparent porosity,bulk density,cold crushing strength and cold modulus of rupture of Al2 O3-MgO castables were investigated. The results show that:( 1) with PBR or PFR40,the castables with0. 4 mass% WS own better performance than those with0. 2 mass% FS or 1 mass% AD;( 2) compared with the castables with CL-CT composite powder, the castables with PFR40-AC34 B5 composite powder have slightly higher flow value; with the decreasing ratio of PFR40 and AC34 B5,or the decreasing ratio of CL andCT,the castables have declined flow value and the dried castable specimens have decreased density but the mildly changed strength; in consideration of the high price of reactive alumina,a proper compositing ratio shall be selected. | WANG Qingheng LI Yuanbing WEI Hao XU Nana LI Shujing LUO Han XIANG Ruofei | 2018 | China's Refractories2018，27，3： | 0 |
| 4 | Identification of potential pathogenic mutations in Chinese children with first branchial cleft anomalies detected by whole-exome sequencing显示文摘Importance:First branchial cleft anomalies(FBCAs)are rare congenital malformations,accounting for<8%of all branchial cleft anomalies.However,little is currently known about the cause of FBCAs at the molecular level.Objective:To identify genomic alterations related to the genetic etiology of FBCAs in Chinese children.Methods:We performed whole-exome sequencing of samples from 10 pediatric patients with FBCAs.Data analysis was carried out using the Burrow-Wheeler Alignment software package,and the dbSNP database for comparisons.Rare variants were further validated by Sanger sequencing.Insertion/deletions(indels)were examined using the Genome Analysis Toolkit.Results:We identified 14 non-synonymous mutations in seven potential FBCA-susceptibility genes(TRAPPC12,NRP2,NPNT,SH3RF2,RHPN1,TENM4,and ARMCX4).We also detected 133 shared small indels in 125 genes.Gene Ontology analysis indicated that most of the identified genes played critical roles in development and differentiation pathways involved in regulating organ development.Interpretation:We characterized the mutational landscape in pathways involved in development and differentiation in Chinese children with FBCA.The results identified potential pathogenic genes and mutations related to FBCA,and provide molecular-level support for the branchial theory of FBCA pathogenesis. | Yeran Yang Wei Liu Yaqiong Jin Min Chen Jie Lu Yongbo Yu Huimin Ren Shujing Han Ping Chu Yongli Guo Jie Zhang Xin Ni | 2021 | Pediatric Investigation2021，5，3： | 0 |
| 5 | scRNA-seq profiling of neonatal and adult thymus-derived CD4+ T cells by a T cell origin-time tracing model显示文摘It is well documented that the neonatal thymus-derived (neonatal-TD) regulatory T cells (Treg) are essential to prevent lethal autoimmune diseases and allergies, and neonatal and adult thymus possesses distinct output potentials for naïve T cells, including Treg. However, the molecular features and detailed functional differences between neonatal-TD and adult thymus-derived (adult-TD) T cells in terms of their ability to maintain immune homeostasis during long-term environmental influences are still largely unknown, partially due to the lack of appropriate animal models to precisely trace these cells at specific time points. In this study, neonatal-TD and adult-TD CD4+ T cells from the spleen and Peyer's patches were traced for 9 weeks by a T cell origin-time tracing mouse model and analysed by single-cell RNA sequencing. More Treg but fewer naïve T cells were found in neonatal-TD CD4+ T cells from both tissues than those from adult-TD counterparts. Interestingly, the neonatal-TD Treg in both the spleen and Peyer's patches exhibited augmented expression of Foxp3, Gata3, Ctla4, Icos, Il2ra, Tgfb1, and Nrp1, as well as enriched Gene Ontology terms like T cell activation and tolerance induction, indicating an enhanced immunosuppressive function. These results were further confirmed by flow cytometry analysis and in vitro immune suppression assays. Flow cytometry also revealed a significantly higher proportion of neonatal-TD Treg in total Treg than that of adult-TD counterparts, suggesting the longer lifespan of neonatal-TD Treg. To investigate the intrinsic features of neonatal-TD and adult-TD CD4+ T cells, a shortened tracing time was performed. Surprisingly, the neonatal-TD and adult-TD CD4+ T cells had similar proportions of Treg and did not exhibit significant differences in Foxp3, Gata3, Ctla4, Icos, Il2ra, and Tgfb1 expression levels after tracing for 12 days. On the other hand, neonatal-TD Treg present an increased Nrp1 expression level compared with adult-TD counterparts, indicating the enhanced stability. Together, our work reveals that the neonatal-TD Treg are more immunosuppressive, which is likely shaped primarily by environmental factors. | Yuheng Han Xinxing Ouyang Yao Chen Shujing Lai Hongxiang Sun Ningbo Wu Chun Ruan Limin Lu Bing Su | 2022 | Journal of Molecular Cell Biology2022，14，12： | 0 |
