| 1 | Single-cell transcriptomic atlas of primate cardiopulmonary aging显示文摘Aging is a major risk factor for many diseases,especially in highly prevalent cardiopulmonary comorbidities and infectious diseases including Coronavirus Disease 2019(COVID-19).Resolving cellular and molecular mechanisms associated with aging in higher mammals is therefore urgently needed.Here,we created young and old non-human primate single-nucleus/cell transcriptomic atlases of lung,heart and artery,the top tissues targeted by SARS-CoV-2.Analysis of cell type-specific aging-associated transcriptional changes revealed increased systemic inflammation and compromised virus defense as a hallmark of cardiopulmonary aging.With age,expression of the SARS-CoV-2 receptor angiotensin-converting enzyme 2(ACE2)was increased in the pulmonary alveolar epithelial barrier,cardiomyocytes,and vascular endothelial cells.We found that interleukin 7(IL7)accumulated in aged cardiopulmonary tissues and induced ACE2 expression in human vascular endothelial cells in an NF-κB-dependent manner.Furthermore,treatment with vitamin C blocked IL7-induced ACE2 expression.Altogether,our findings depict the first transcriptomic atlas of the aged primate cardiopulmonary system and provide vital insights into age-linked susceptibility to SARS-CoV-2,suggesting that geroprotective strategies may reduce COVID-19 severity in the elderly. | Shuai Ma Shuhui Sun Jiaming Li Yanling Fan Jing Qu Liang Sun Si Wang Yiyuan Zhang Shanshan Yang Zunpeng Liu Zeming Wu Sheng Zhang Qiaoran Wang Aihua Zheng Shuguang Duo Yang Yu Juan Carlos Izpisua Belmonte Piu Chan Qi Zhou Moshi Song Weiqi Zhang Guang-Hui Liu | 2021 | Cell Research2021，31，4： | 10 |
| 2 | Germline mutation analysis of hPMS2 gene in Chinese families with hereditary nonpolyposis colorectal cancer显示文摘AIM: To study the germline mutation of hPMS2 gene in 26 unrelated Chinese hereditary nonpolyposis colorectal cancer (HNPCC) probands and to fulfill the screening strategy for HNPCC in Chinese. METHODS: Genomic DNA was extracted from the peripheral blood. To avoid the interference of pseudogene in detection of the remaining 11 exons (exon 1-5, 9, 11-15), long-range polymerase chain reaction (PCR) was conducted to amplify the complete coding region of hPMS2 gene firstly. Then 1/8 of the PCR productswere used as template to amplify the individual exon respectively and DNA sequencing was done. Direct DNA sequencing of the conventional PCR products of exon 6, 7, 8 and 10 of hPMS2 gene was performed. The same analysis was made in 130 healthy persons without family histories of HNPCC to further investigate the pathological effects of the detected missense mutation. RESULTS: One HNPCC proband fulf illed Bethesda guidelines and was found to carry the germline mutation of hPMS2 gene, which has not been reported in Chinese HNPCC families. It was a missense mutation at c.1532C>T of exon 11. It was detected in three controls as well with an occurrence rate of 2.3% (3/130). Since it could not be found in the PMS2-single nucleotide polymorphism (SNP) database, this missense mutation is a new SNP unreported up to date. Meanwhile, 260 reported SNPs of hPMS2 gene were detected in the 26 HNPCC probands. The 2nd and 5th exons were probably the hot SNP regions of hPMS2 gene in Chinese HNPCC families involving 53.1% of all reported SNP. CONCLUSION: The germline mutation of hPMS2 gene may be rare in Chinese HNPCC families. The 2nd and 5th exons are hot SNP regions of hPMS2 gene. | Xia Sheng, Xiao-Yan Zhou, Xiang Du, Tai-Ming Zhang, WeiQi Sheng, Da-Ren Shi, Department of Pathology, Shanghai Cancer Center, Fudan University, Shanghai 200032, China Department of Oncology, Shanghai Medical College, Fudan University, Shanghai 200032, China Heng-Hua Zhou, Department of Pathology, Shanghai Ninth People’s Hospital Affi liated to Shanghai Jiao Tong University School of Medicine, Shanghai 200011, China San-Jun Cai, Department of Abdominal Surgery, Cancer Center, Fudan University, Shanghai 200032, China | 2010 | World Journal of Gastroenterology2010，16，30： | 6 |

| 7 | FTO stabilizes MIS12 and counteracts senescence显示文摘Dear Editor, N6-methyladenosine(m6A)is an abundant epitranscriptomic modification that regulates messenger RNA(mRNA)biology.The m6A modification regulates mRNA splicing,transport,stability,and translation through coordinated activities by methyltransferases(writers),binding proteins(readers),and demethylases(erasers)(Huang et al.,2020;Wu et al.,2020).Among m6A regulators,fat mass of obesity-associ-ated protein(FTO),is the first discovered eraser with RNA m6A demethylation activity(Jia et al.,2011).Since then,FTO has been reported to play m6A-dependent roles in a variety of physiological processes including adipogenesis,neuro-genesis and tumorigenesis(Fischer et al.,2009;Li et al.,2017;Huang et al.,2020).Consequently,FTO deficiency in mice leads to dramatic phenotypes,such as decreased fat mass and impaired brain development(Fischer et al.,2009;Li et al.,2017).Similarly,inhibition of FTO reduces tumori-genesis in multiple types of cancer models,while FTO is highly expressed in many cancers(Huang et al.,2020). | Sheng Zhang Zeming Wu Yue Shi Si Wang Jie Ren Zihui Yu Daoyuan Huang Kaowen Yan Yifang He Xiaoqian Liu Qianzhao Ji Beibei Liu Zunpeng Liu Jing Qu Guang-Hui Liu Weimin Ci Xiaoqun Wang Weiqi Zhang | 2022 | Protein & Cell2022，13，12： | 0 |
| 8 | ALKBH1 deficiency leads to loss of homeostasis in human diploid somatic cells显示文摘Dear Editor,As the most prevalent DNA methylation modification in prokaryotes,DNA N6 methyladenosine(6mA)in eukaryotic genomes has recently been observed in diverse species including Caenorhabditis elegans(Greer et al.,2015),Dro-sophila melanogaster(Zhang et al,2015),mouse(Wu et al,2016)and human(Xiao et al,2018).6mA has been reported to associate with multiple physiological processes including embryonic development and tumorigenesis(Greer et al.,2015;Zhang et al.,2015;Xie et al.,2018),yet some con-troversies exist.In contrast to the findings showing that ALKBH1(alkB homolog 1)is a primary 6mA demethylase in mouse and human cells(Wu et al.,2016;Xiao et al.,2018;Xie et al..2018),other studies indicate that ALKBH1 is prone to demethylate 6mA on bubbled or bulged DNAs that are often featured by a locally unpairing region with flanking duplex,such as D-loop,R-loop as well as DNA or RNA stem-loop,and single-stranded DNAs at a lower efficiency. | Hongyu Li Zeming Wu Xiaoqian Liu Sheng Zhang Qianzhao Ji Xiaoyu Jiang Zunpeng Liu Si Wang Jing Qu Weiqi Zhang Moshi Song Eli Song Guang-Hui Liu | 2020 | Protein & Cell2020，11，9： | 0 |
| 9 | Microwave Drying of Scots Pine Lumber:Structure Changes,Its Effect on Liquid Permeability显示文摘Microwave(MW)drying method was adopted to enhance the liquid permeability of Scots pine lumber.Structure changes were characterized by stereoscope microscope,scanned electron microscope(SEM)and transmission electron microscope(TEM)examination.Pore parameters before and after MW treatment were detected by mercury intrusion porosimetry(MIP)method,and the effect of structure changes on liquid permeability were analyzed.As stereoscope microscope,SEM and TEM examination results showed,macro and micro checks mainly developed at intercellcular of tracheids,intercellular of ray parenchyma and tracheid,while these checks extend main along the radial-longitudinal plane.Pit border destruction,aspirated pits’orus translocation and micro-checks in tracheid cell wall were also observed.MIP test shown that pore volume and pore area increased as macro and micro checks generated to form new cavities.Microstructure changes would increase the quantity of pores or enlarge the pore diameter.Liquid flow pathways increased as macro and micro checks generated,aspirated pits reopened to form new pathways;liquid flow efficiency improved as porosity,pore volume and pore diameter increased which facilitated the liquid flow. | Sheng He Weiqi Leng Yuhe Chen Hongchen Li Jingpeng Li Zaixing Wu Zizhang Xiao | 2023 | Journal of Renewable Materials2023，11，1： | 0 |
| 10 | 4E-BP1 counteracts human mesenchymal stem cell senescence via maintaining mitochondrial homeostasis显示文摘Although the mTOR-4E-BP1 signaling pathway is implicated in aging and aging-related disorders,the role of 4E-BP1 in regulating human stem cell homeostasis remains largely unknown.Here,we report that the expression of 4E-BP1 decreases along with the senescence of human mesenchymal stem celis(hMSCs).Genetic inactivation of 4E-BP1 in hMSCs compromises mitochondrial respiration,increases mitochondrial reactive oxygen species(Ros)production,and accelerates cellular senescence.Mechanistically,the absence of 4E-BP1 destabilizes proteins in mitochondrial respiration complexes,especially several key subunits of complex III including UQCRC2.Ectopic expression of 4E-BP1 attenuates mitochondrial abnormalities and alleviates cellular senescence in 4E-BP1-deficient hMSCs as well as in physiologically aged hMSCs.These findings together demonstrate that 4E-BP1 functions as a geroprotector to mitigate human stem cell senescence and maintain mitochondrial homeostasis,particularly for the mitochondrial respiration complex Il,thus providing a new potential target to counteract human stem cell senescence. | Yifang He Qianzhao Ji Zeming Wu Yusheng Cai Jian Yin Yiyuan Zhang Sheng Zhang Xiaoqian Liu Weiqi zhang Guang-Hui Liu Si Wang Moshi Song Jing Qu | 2023 | Protein & Cell2023，14，3： | 0 |
