| 1 | Novel MSX1 variants identified in families with nonsyndromic oligodontia显示文摘The goal of this study was to identify MSX1 gene variants in multiple Chinese families with nonsyndromic oligodontia and analyse the functional influence of these variants.Whole-exome sequencing(WES)and Sanger sequencing were performed to identify the causal gene variants in five families with nonsyndromic oligodontia,and a series of bioinformatics databases were used for variant confirmation and functional prediction.Phenotypic characterization of the members of these families was described,and an in vitro analysis was performed for functional evaluation.Five novel MSX1 heterozygous variants were identified:three missense variants[c.662A>C(p.Q221P),c.670C>T(p.R224C),and c.809C>T(p.S270L)],one nonsense variant[c.364G>T(p.G122*)],and one frameshift variant[c.277delG(p.A93Rfs*67)].Preliminary in vitro studies demonstrated that the subcellular localization of MSX1 was abnormal with the p.Q221P,p.R224C,p.G122*,and p.A93Rfs*67 variants compared to the wild type.Three variants(p.Q221P,p.G122*,and p.A93Rfs*67)were classified as pathogenic or likely pathogenic,while p.S270L and p.R224C were of uncertain significance in the current data.Moreover,we summarized and analysed the MSX1-related tooth agenesis positions and found that the type and variant locus were not related to the severity of tooth loss.Our results expand the variant spectrum of nonsyndromic oligodontia and provide valuable information for genetic counselling. | Jinglei Zheng Miao Yu Haochen Liu Tao Cai Hailan Feng Yang Liu Dong Han | 2021 | International Journal of Oral Science2021，13，1： | 4 |
| 2 | Generation of tooth-like structures from integration-free human urine induced pluripotent stem cells显示文摘Background:Tooth is vital not only for a good smile,but also good health.Yet,we lose tooth regularly due to accidents or diseases.An ideal solution to this problem is to regenerate tooth with patients’own cells.Here we describe the generation of tooth-like structures from integration-free human urine induced pluripotent stem cells(ifhU-iPSCs).Results:We first differentiated ifhU-iPSCs to epithelial sheets,which were then recombined with E14.5 mouse dental mesenchymes.Tooth-like structures were recovered from these recombinants in 3 weeks with success rate up to 30%for 8 different iPSC lines,comparable to H1 hESC.We further detected that ifhU-iPSC derived epithelial sheets differentiated into enamel-secreting ameloblasts in the tooth-like structures,possessing physical properties such as elastic modulus and hardness found in the regular human tooth.Conclusion:Our results demonstrate that ifhU-iPSCs can be used to regenerate patient specific dental tissues or even tooth for further drug screening or regenerative therapies. | Jinglei Cai Yanmei Zhang Pengfei Liu Shubin Chen Xuan Wu Yuhua Sun Ang Li Ke Huang Rongping Luo Lihui Wang Ying Liu Ting Zhou Shicheng Wei Guangjin Pan Duanqing Pei | 2013 | Cell Regeneration2013，2，1： | 4 |
| 3 | Neural progenitor cells from human induced pluripotent stem cells generated less autogenous immune response显示文摘The breakthrough development of induced pluripotent stem cells(iPSCs)raises the prospect of patient-specific treatment for many diseases through the replacement of affected cells.However,whether iPSC-derived functional cell lineages generate a deleterious immune response upon auto-transplantation remains unclear.In this study,we differentiated five human iPSC lines from skin fibroblasts and urine cells into neural progenitor cells(NPCs)and analyzed their immunogenicity.Through co-culture with autogenous peripheral blood mononuclear cells(PBMCs),we showed that both somatic cells and iPSC-derived NPCs do not stimulate significant autogenous PBMC proliferation.However,a significant immune reaction was detected when these cells were co-cultured with allogenous PBMCs.Furthermore,no significant expression of perforin or granzyme B was detected following stimulation of autogenous immune effector cells(CD3+CD8 T cells,CD3+CD8+T cells or CD3 CD56+NK cells)by NPCs in both PBMC and T cell co-culture systems.These results suggest that human iPSC-derived NPCs may not initiate an immune response in autogenous transplants,and thus set a base for further preclinical evaluation of human iPSCs. | HUANG Ke LIU PengFei LI Xiang CHEN ShuBin WANG LiHui QIN Li SU ZhengHui HUANG WenHao LIU JuLi JIA Bei LIU Jie CAI JingLei PEI DuanQing PAN GuangJin | 2014 | Science China(Life Sciences)2014，57，2： | 3 |

| 5 | Boosting photocatalytic hydrogen evolution of g-C_(3)N_(4) catalyst via lowering the Fermi level of co-catalyst显示文摘The photocatalytic performances are highly dependent on the charge separation and surface reaction kinetics of photocatalysts.Aiming at figuring out the effects of co-catalyst with the lower Fermi level on photocatalytic activity,we tuned the Fermi level of Pt nanoparticles on g-C_(3)N_(4)(GCN)by introducing Co atom.Experimental results show that lowering the Fermi level of co-catalyst does not alter light absorption of GCN due to the invariable structure.Besides,Pt_(3)Co with a lower Fermi level contributes less positive influence on charge separation in GCN due to an opposite effect from the stronger electron-trap ability of Pt_(3)Co and increased band bending in GCN-Pt_(3)Co.The density functional theory(DFT)calculations indicate that GCN-Pt_(3)Co has faster surface reaction kinetics than GCN-Pt,owing to easier dissociation of H_(2)O molecules and faster desorption of H^(*)on Pt_(3)Co.Consequently,GCN-Pt_(3)Co exhibits an excellent H_(2) evolution rate with 2.91 mmol g^(-1)·h^(-1),which 2.67 times that of GCN-Pt. | Hairui Cai Bin Wang Laifei Xiong Jinglei Bi Hanjing Hao Xiaojing Yu Chao Li Jiamei Liu Shengchun Yang | 2022 | Nano Research2022，15，2： | 2 |

| 12 | GATA2^(−/−) human ESCs undergo attenuatedendothelial to hematopoietic transition andthereafter granulocyte commitment显示文摘Background: Hematopoiesis is a progressive process collectively controlled by an elaborate network of transcriptionfactors (TFs). Among these TFs, GATA2 has been implicated to be critical for regulating multiple steps of hematopoiesisin mouse models. However, whether similar function of GATA2 is conserved in human hematopoiesis, especially duringearly embryonic development stage, is largely unknown.Results: To examine the role of GATA2 in human background, we generated homozygous GATA2 knockout humanembryonic stem cells (GATA2^(−/−) hESCs) and analyzed their blood differentiation potential. Our results demonstratedthat GATA2^(−/−) hESCs displayed attenuated generation of CD34^(+)CD43^(+) hematopoietic progenitor cells (HPCs), due tothe impairment of endothelial to hematopoietic transition (EHT). Interestingly, GATA2^(−/−) hESCs retained the potentialto generate erythroblasts and macrophages, but never granulocytes. We further identified that SPI1 downregulationwas partially responsible for the defects of GATA2^(−/−) hESCs in generation of CD34^(+)CD43^(+) HPCs and granulocytes.Furthermore, we found that GATA2^(−/−) hESCs restored the granulocyte potential in the presence of Notch signaling.Conclusion: Our findings revealed the essential roles of GATA2 in EHT and granulocyte development throughregulating SPI1, and uncovered a role of Notch signaling in granulocyte generation during hematopoiesis modeled byhuman ESCs. | Ke Huang Juan Du Ning Ma Jiajun Liu Pengfei Wu Xiaoya Dong Minghui Meng Wenqian Wang Xin Chen Xi Shi Qianyu Chen Zhongzhou Yang Shubin Chen Jian Zhang Yuhang Li Wei Li Yi Zheng Jinglei Cai Peng Li Xiaofang Sun Jinyong Wang Duanqing Pei Guangjin Pan | 2015 | Cell Regeneration2015，4，1： | 0 |
| 13 | Divergent allocations of nonstructural carbohydrates shape growth response to rainfall reduction in two subtropical plantations显示文摘Nonstructural carbohydrates(NSC)are indicators of tree carbon balance and play an important role in regulating plant growth and survival.However,our understanding of the mechanism underlying drought-induced response of NSC reserves remains limited.Here,we conducted a long-term throughfall exclusion(TFE)experiment to investigate the seasonal responses of NSC reserves to manipulative drought in two contrasting tree species(a broadleaved tree Castanopsis hystrix Miq.and a coniferous tree Pinus massoniana Lamb.)of the subtropical China.We found that in the dry season,the two tree species differed in their responses of NSC reserves to TFE at either the whole-tree level or by organs,with significantly depleted total NSC reserves in roots in both species.Under the TFE treatment,there were significant increases in the NSC pools of leaves and branches in C.hystrix,which were accompanied by significant decreases in fine root biomass and radial growth without significant changes in canopy photosynthesis;while P.massoniana exhibited significant increase in fine root biomass without significant changes in radial growth.Our results suggested that under prolonged water limitation,NSC usage for growth in C.hystrix is somewhat impaired,such that the TFE treatment resulted in NSC accumulation in aboveground organs(leaf and branch);whereas P.massoniana is capable of efficiently utilizing NSC reserves to maintain its growth under drought conditions.Our findings revealed divergent NSC allocations under experimental drought between the two contrasting tree species,which are important for better understanding the differential impacts of climate change on varying forest trees and plantation types in subtropical China. | Xinwei Guo Shirong Liu Hui Wang Zhicheng Chen Jinglei Zhang Lin Chen Xiuqing Nie Lu Zheng Daoxiong Cai Hongyan Jia Baoliang Niu | 2022 | Forest Ecosystems2022，9，2： | 0 |
| 14 | TMEM106A transcriptionally regulated by promoter methylation is involved in invasion and metastasis of hepatocellular carcinoma显示文摘Expression of transmembrane protein 106A(TMEM106A)has been reported to be dysregulated in several types of cancers.However,the role of TMEM106A in hepatocellular carcinoma(HCC)is still unknown.In the present study,we demonstrate that TMEM106A is markedly downregulated in HCC compared with normal liver tissue.In particular,tumor-specific DNA methylation of TMEM106A is frequently observed in tumor tissues from HCC patients.Immunohistochemistry and pyrosequencing reveal a significant relationship between TMEM106A methylation and downregulation of protein expression.Receiver operating characteristic(ROC)curve analysis reveals that methylation of TMEM106A in tumor samples is different from that in non-malignant adjacent tissues of HCC patients.Moreover,HCC patients with TMEM106A hypermethylation have a poor clinical prognosis.5-Aza-2′-deoxycytidin treatment of hypermethylated TMEM106A in highly metastatic HCC cells increases the expression of TMEM106A.Functional assays reveal that overexpression of TMEM106A significantly suppresses the malignant behavior of HCC cells in vitro and decreases tumorigenicity and lung metastasis in vivo.Mechanistically,TMEM106A inhibits epithelial mesenchymal transition(EMT)of HCC cells through inactivation of the Erk1/2/Slug signaling pathway.In conclusion,our findings demonstrate that TMEM106A is an inhibitor of HCC EMT and metastasis,and TMEM106A is often transcriptionally downregulated by promoter methylation,which results in reduced levels of TMEM106A protein and predicts poor survival outcomes for HCC patients. | Shiming Shi Biao Wang Jinglei Wan Lina Song Guiqi Zhu Junxian Du Luxi Ye Qianqian Zhao Jialiang Cai Qing Chen Kun Xiao Jian He Lei Yu Zhi Dai | 2022 | Acta Biochimica et Biophysica Sinica2022，54，7： | 0 |
| 15 | Efficient induction of neural progenitor cells from human ESC/iPSCs on Type I Collagen显示文摘A stable,rapid and effective neural differentiation method is essential for the clinical applications of human embryonic stem cells(ESCs)or induced pluripotent stem cells(iPSCs)in treating neurological disorders and diseases.Herein,we established a novel and robust monolayer differentiation method to produce functional neural progenitor cells(NPCs)from human ESC/iPSCs on Type I Collagen.The derived cells not only displayed the requisite markers,but also behaved similarly to classic NPCs both in vitro and in vivo.Upon transplantation into traumatic brain injury model,the derived NPCs facilitated recovery from injury.We also found that SMAD signaling stayed down throughout the differentiation process on Type I Collagen,and the pluripotent signals were rapidly downregulated along with raising up of neural early markers on the third day.Meanwhile,ATAC-seq data showed the related mediation of distinct transcriptome and global chromatin dynamics during NPC induction.Totally,our results thus provide a convenient way to generate NPCs from human ESC/iPSCs for neural diseases’treatment. | Pengfei Liu Shubin Chen Yaofeng Wang Xiaoming Chen Yiping Guo Chunhua Liu Haitao Wang Yifan Zhao Di Wu Yongli Shan Jian Zhang Chuman Wu Dongwei Li Yanmei Zhang Tiancheng Zhou Yaoyu Chen Xiaobo Liu Chenxu Li Lihui Wang Bei Jia Jie Liu Bo Feng Jinglei Cai Duanqing Pei | 2021 | Science China(Life Sciences)2021，64，12： | 0 |
