1A group of SUVH methyl-DNA binding proteins regulate expression of the DNA demethylase ROS_1 in Arabidopsis显示文摘DNA methylation is typically regarded as a repressive epigenetic marker for gene expression.Genome-wide DNA methylation patterns in plants are dynamically regulated by the opposing activities of DNA methylation and demethylation reactions. In Arabidopsis, a DNA methylation monitoring sequence(MEMS) in the promoter of the DNA demethylase gene ROS_1 functions as a methylstat that senses these opposing activities and regulates genome DNA methylation levels by adjusting ROS_1 expression. How DNA methylation in the MEMS region promotes ROS_1 expression is not known. Here, we show that several Su(var)3-9 homologs(SUVHs) can sense DNA methylation levels at the MEMS region and function redundantly to promote ROS_1 expression. The SUVHs bind to the MEMS region, and the extent of binding is correlated with the methylation level of the MEMS.Mutations in the SUVHs lead to decreased ROS_1 expression, causing DNA hypermethylation at more than 1,000 genomic regions. Thus, the SUVHs function to mediate the activation of gene transcription by DNA methylation.Xinlong Xiao Jieqiong Zhang Tao Li Xing Fu Viswanathan Satheesh Qingfeng Niu Zhaobo Lang Jian-Kang Zhu Mingguang Lei 2019Journal of Integrative Plant Biology2019,61,2:11
2The chimeric genes in the hybrid lineage of Carassius auratus cuvieri(♀)×Carassius auratus red var.(♂)显示文摘Hybridization can combine the genomes of different strains or species, which leads to changes of genotype and phenotype in the hybrids. In this study, we aimed to investigate the genetic variations of hybrids(WR-F1 and WR-F2) derived from the intraspecific hybridization of white crucian carp(Carassius auratus cuvieri, WCC, ♀) and red crucian carp(Carassius auratus red var., RCC, ♂). Here, we compared the orthologous genes in the liver transcriptomes of hybrids with those of WCC and RCC, and classified the orthologous genes into eight gene patterns within three categories(chimera, mutant, and biparental origin genes).The results revealed 19.04%, 4.17% chimeric genes and 6.90%, 5.05% mutations of orthologous genes in WR-F1 and WR-F2 respectively. Seventeen of twenty-three characterized genes(77%) were confirmed to be the chimeras at the genomic DNA level.The GO classification discovered that some chimeric and mutant genes were related to metabolic process, immune system and developmental process in WR-F1. Our results provide the new evidence that hybridization can combine the parental genomes,leading to changes in the genotype of the resultant hybrids. This is the first report on the formation of chimeric genes from fish intraspecific hybridization, which is potentially interesting from the context of both evolution and the genetic breeding of fish.Qingfeng Liu Yanhua Qi Qiuli Liang Xiujuan Xu Fangzhou Hu Jing Wang Jun Xiao Shi Wang Wuhui Li Min Tao Qinbo Qin Rurong Zhao Zhanzhou Yao Shaojun Liu 2018Science China(Life Sciences)2018,61,9:6
3Targeted disruption of tyrosinase causes melanin reduction in Carassius auratus cuvieri and its hybrid progeny显示文摘The white crucian carp(Carassius auratus cuvieri,WCC) not only is one of the most economically important fish in Asia,characterized by strong reproductive ability and rapid growth rates,but also represents a good germplasm to produce hybrid progenies with heterosis.Gene knockout technique provides a safe and acceptant way for fish breeding.Achieving gene knockout in WCC and its hybrid progeny will be of great importance for both genetic studies and hybridization breeding.Tyrosinase(TYR) is a key enzyme in melanin synthesis.Depletion of tyr in zebrafish and mice results in mosaic pigmentation or total albinism.Here,we successfully used CRISPR-Cas9 to target tyr in WCC and its hybrid progeny(WR) derived from the cross of WCC(♀) and red crucian carp(Carassius auratus red var.,RCC,♂).The level of TYR protein was significantly reduced in mutant WCC.Both the mutant WCC and the mutant WR showed different degrees of melanin reduction compared with the wild-type sibling control fish,resulting from different mutation efficiency ranging from 60% to 90%.In addition,the transcriptional expression profiles of a series of pivotal pigment synthesis genes,i.e.tyrp1,mitfa,mitfb,dct and sox10,were down-regulated in tyr-CRISPR WCC,which ultimately caused a reduction in melanin synthesis.These results demonstrated that tyr plays a key role in melanin synthesis in WCC and WR,and CRISPR-Cas9 is an effective tool for modifying the genome of economical fish.Furthermore,the tyr-CRISPR models could be valuable in understanding fundamental mechanisms of pigment formation in non-model fish.Qingfeng Liu Yanhua Qi Qiuli Liang Jia Song Junmei Liu Wuhui Li Yuqin Shu Min Tao Chun Zhang Qinbo Qin Jing Wang Shaojun Liu 2019Science China(Life Sciences)2019,62,9:4

5Geochemical provenancing and direct dating of the Harbin archaic human cranium显示文摘As one of the most complete archaic human fossils,the Harbin cranium provides critical evidence for studying the diversification of the Homo genus and the origin of Homo sapiens.However,the unsystematic recovery of this cranium and a long and confused history since the discovery impede its accurate dating.Here,we carried out a series of geochemical analyses,including non-destructive X-ray fluorescence(XRF),rare earth elements(REE),and the Sr isotopes,to test the reported provenance of the Harbin cranium and get better stratigraphic constraints.The results show that the Harbin cranium has very similar XRF element distribution patterns,REE concentration patterns,and Sr isotopic compositions to those of the Middle Pleistocene-Holocene mammalian and human fossils recently recovered from the Harbin area.The sediments adhered in the nasal cavity of the Harbin cranium have a 87Sr/86Sr ratio of 0.711898,falling in the variation range measured in a core drilled near the Dongjiang Bridge,where the cranium was discovered during its reconstruction.The regional stratigraphic correlations indicate that the Harbin cranium was probably from the upper part of the Upper Huangshan Formation of the Harbin area,which has an optically stimulated luminescence dating constraint between 138 and 309 ka.U-series disequilibrium dating(n=10)directly on the cranium suggests that the cranium is older than 146 ka.The multiple lines of evidence from our experiments consistently support the theory that the Harbin cranium is from the late Middle Pleistocene of the Harbin area.Our study also shows that geochemical approaches can provide reliable evidence for locating and dating unsystematically recovered human fossils,and potentially can be applied to other human fossils without clear provenance and stratigraphy records.Qingfeng Shao Junyi Ge Qiang Ji Jinhua Li Wensheng Wu Yannan Ji Tao Zhan Chi Zhang Qiang Li Rainer Grun Chris Stringer Xijun Ni 2021The Innovation2021,2,3:3
6Nsp2 has the potential to be a drug target revealed by global identification of SARS-CoV-2 Nsp2-interacting proteins显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has become a global health threat since December 2019,and there is still no highly effective drug to control the pandemic.To facilitate drug target identification for drug development,studies on molecular mechanisms,such as SARS-CoV-2 protein interactions,are urgently needed.In this study,we focused on Nsp2,a non-structural protein with largely unknown function and mechanism.The interactome of Nsp2 was revealed through the combination of affinity purification mass spectrometry(AP-MS)and stable isotope labeling by amino acids in cell culture(SILAC),and 84 proteins of high-confidence were identified.Gene ontology analysis demonstrated that Nsp2-interacting proteins are involved in several biological processes such as endosome transport and translation.Network analysis generated two clusters,including ribosome assembly and vesicular transport.Bio-layer interferometry(BLI)assay confirmed the bindings between Nsp2-and 4-interacting proteins,i.e.STAU2(Staufen2),HNRNPLL,ATP6V1B2,and RAP1GDS1(SmgGDS),which were randomly selected from the list of 84 proteins.Our findings provide insights into the Nsp2–host interplay and indicate that Nsp2 may play important roles in SARS-CoV-2 infection and serve as a potential drug target for anti-SARS-CoV-2 drug development.Yun-Xiao Zheng Lei Wang Wei-Sha Kong Hong Chen Xue-Ning Wang Qingfeng Meng Hai-Nan Zhang Shu-Juan Guo He-Wei Jiang Sheng-Ce Tao 2021Acta Biochimica et Biophysica Sinica2021,53,9:3
7Study of brain morphology change in Alzheimer’s disease and amnestic mild cognitive impairment compared with normal controls显示文摘Background With an aggravated social ageing level, the number of patients with Alzheimer's disease (AD) is gradually increasing, and mild cognitive impairment (MCI) is considered to be an early form of Alzheimer's disease. How to distinguish diseases in the early stage for the purposes of early diagnosis and treatment is an important topic. Aims The purpose of our study was to investigate the differences in brain cortical thickness and surface area among elderly patients with AD, elderly patients with amnestic MCI (aMCI) and normal controls (NC). Methods 20 AD patients, 21 aMCIs and 25 NC were recruited in the study. FreeSurfer software was used to calculate cortical thickness and surface area among groups. Results The patients with AD had less cortical thickness both in the left and right hemisphere in 17 of the 36 brain regions examined than the patients with aMCI or NC. The patients with AD also had smaller cerebral surface area both in the left and right hemisphere in 3 of the 36 brain regions examined than the patients with aMCI or NC. Compared with the NC, the patients with aMCI only had slight atrophy in the inferior parietal lobe of the left hemisphere, and no significant difference was found. Conclusion AD, as well as aMCI (to a lesser extent), is associated with reduced cortical thickness and surface area in a few brain regions associated with cognitive impairment. These results suggest that cortical thickness and surface area could be used for early detection of AD.Huanqing Yang Hua Xu Qingfeng Li Yan Jin Weixiong Jiang Jinghua Wang Yina Wu Wei Li Cece Yang Xia Li Shifu Xiao Feng Shi Tao Wang 2019General Psychiatry2019,32,2:3
8A modified scar model with controlled tension on secondary wound healing in mice显示文摘Pathological scars might cause a distorted appearance and restricted mobility,and the study of scar pathophysiology has been hindered by the absence of a reliable model.In this study,we introduce a model with a modified device to induce controlled tension on a wound healing by secondary intention to overcome the shortcomings of the model generated by Aarabi et al.We investigated and recommend an induction of 0.1 N/mm^(2) tension on day 7 for 14 days to mimic the characteristics of human scars.A 3.5-fold increase in scar tissue and a 2-fold increase in collagen production were induced by the modified model.Histologically,the modified method increased scar thickness.However,no significant difference was found in cell density between the two groups.This modified procedure significantly increased scar tissue,which could be used for further cellular and biomolecular research.The mechanical force applied to the wound became measurable and controllable.This method is more convenient for researchers to observe in realtime and for providing timely adjustments of the tension used in this modified model.Zi Wang Xin Huang Tao Zan Qingfeng Li Haizhou Li 2020Burns & Trauma2020,8,1:2

11miR-199-5p regulates spermiogenesis at the posttranscriptional level via targeting Tekt1 in allotriploid crucian carp显示文摘Background:Sperm abnormalities are one of the primary factors leading to male sterility,but their pathogenesis is still unclear.Although miRNAs are suggested to exert important roles in the regulation of spermatogenesis at both transcriptional and posttranscriptional levels,little is currently known regarding the regulation of sperm flagella assembly by microRNAs(miRNAs).The role of miRNAs in the development of sperm abnormalities in sterile triploid fish has not been studied.Results:In this study,we found that miR-199-5p was widely expressed in all detected tissues of different-ploidy crucian carp.As one of the testis-specific candidate markers,Tekt1 was predominantly expressed in the testis.Quantitative real-time PCR(qRT-PCR)analyses showed that the expression trend of miR-199-5p was exactly opposite to that of Tekt1.Through bioinformatics analysis,we identified a putative miR-199-5p binding site in the Tekt1 mRNA.We further identified Tekt1 as a target of miR-199-5p using luciferase reporter assay.Finally,we confirmed that miR-199-5p was necessary for sperm flagellar assembly and spermatogenesis in vivo via intraperitoneal injection of miR-199-5p antagomir or agomir in diploid red crucian carp.Moreover,miR-199-5p gainof-function could lead to spermatids apoptosis and abnormal spermatozoa structure,which is similar to that of allotriploid crucian carp.Conclusions:Our studies suggested that abnormally elevated miR-199-5p inhibited the sperm flagella formation in spermiogenesis by negatively regulating the expression of Tekt1,thereby causing sperm abnormalities of male allotriploid crucian carp.Shengnan Li Qiubei Wang Lu Huang Siyu Fan Ting Li Yuqing Shu Chun Zhang Yi Zhou Qingfeng Liu Kaikun Luo Min Tao Shaojun Liu 2022Journal of Animal Science and Biotechnology2022,13,5:1

14A joint call for actions to advance taxonomy in China显示文摘Taxonomy plays an important role in understanding the origin, evolution, and ecological functionality of biodiversity. There are large number of unknown species yet to be described by taxonomists, which together with their ecosystem services cannot be effectively protected prior to description. Despite this, taxonomy has been increasingly underrated insufficient funds and permanent positions to retain young talents. Further, the impact factordriven evaluation systems in China exacerbate this downward trend, so alternative evaluation metrics are urgently necessary. When the current generation of outstanding taxonomists retires,there will be too few remaining taxonomists left to train the next generation. In light of these challenges, all co-authors worked together on this paper to analyze the current situation of taxonomy and put out a joint call for immediate actions to advance taxonomy in China.Chaodong Zhu Arong Luo Ming Bai Michael COrr Zhonge Hou Siqin Ge Jun Chen Yibo Hu Xuming Zhou Gexia Qiao Hongzhi Kong Limin Lu Xiaohua Jin Lei Cai Xinli Wei Ruilin Zhao Wei Miao Qingfeng Wang Zhongli Sha Qiang Lin Meng Qu Jianping Jiang Jiatang Li Jing Che Xuelong Jiang Xiaoyong Chen Lianming Gao Zongxin Ren Chunlei Xiang Shixiao Luo Donghui Wu Dong Liu Yanqiong Peng Tao Su Chenyang Cai Tianqi Zhu Wanzhi Cai Xingyue Liu Hu Li Huaijun Xue Zhen Ye Xuexin Chen Pu Tang Shujun Wei Hong Pang Qiang Xie Feng Zhang Feng Zhang Xianjin Peng Aibing Zhang Taiping Gao Changfa Zhou Chen Shao Libin Ma Zhaoming Wei Yunxia Luan Ziwei Yin Wu Dai Cong Wei Xiaolei Huang Jingxian Liu Xiangsheng Chen Tianci Yi Zhisheng Zhang Zhulidezi Aishan Qin Li Hongying Hu 2022Zoological Systematics2022,47,3:1

19The binding epitope of sintilimab on PD-1 revealed by AbMap显示文摘PD-1 plays an important role as an immune checkpoint.Sintilimab is a newly approved PD-1 antibody for cancer immunotherapy with an unknown binding epitope on PD-1.In this study,to elucidate the molecular mechanism by which sintilimab blocks PD-1 activation,we applied Antibody binding epitope Mapping(AbMap)to identify the binding epitope of sintilimab.An epitope was successfully identified,i.e.SLAPKA,aa 127-132.By constructing a series of point mutations,the dominant residues S127,L128,A129,P130,and A132 of PD-1 were further validated by western blot analysis,biolayer interferometry,and flow cytometry.Structural analysis showed that the epitope is partially within the binding interface of PD-1 and PD-L1,and this epitope also partially overlaps with that of nivolumab and pembrolizumab.These results demonstrate that sintilimab can attenuate PD-1 activation by directly competing with the interaction between PD-1 and PD-L1 through binding with the key residues of the FG loop on PD-1.This study also demonstrates the high efficiency and accuracy of AbMap for determining the binding epitope of therapeutic antibodies.Mingliang Ma Huan Qi Chuansheng Hu Zhaowei Xu Fanlin Wu Nan Wang Danyun Lai Yang Li Hainan Zhang Hewei Jiang Qingfeng Meng Shujuan Guo Yani Kang Xiaodong Zhao Hua Li Sheng-ce Tao 2021Acta Biochimica et Biophysica Sinica2021,53,5:1
