| 2 | Biodegradable nanocarriers for small interfering ribonucleic acid (siRNA) co-delivery strategy increase the chemosensitivity of pancreatic cancer cells to gemcitabine显示文摘Ribonucleic acid (RNA) interference (RNAi) therapies are promising cancertreatment modalities that can specifically target abnormal proto-oncogenes, thusimproving the therapeutic effect. For the treatment of pancreatic cancer, targetingone mutant proto-oncogene by RNAi usually does not yield the desired therapeuticefficiency. Both K-ras gene mutations and Notch1 overexpression are commonsymptoms in pancreatic cancer patients, and play a crucial role in pancreaticcancer cell drug resistance. In this study, biodegradable charged polyester-basedvectors (BCPVs) were synthesized for the co-delivery of K-ras and Notch1 smallinterfering ribonucleic acid (siRNA) into MiaPaCa-2 cells (pancreatic cancercell line) to overcome drug resistance to gemcitabine (GEM), a first-line chem-otherapeutic drug used in the clinic. BCPVs could effectively absorb negative siRNAto form a capsule-like structure, prevent siRNA from nuclease digestion in theserum, and promote effective siRNA cell internalization and endosomal escape.Through K-ras and Notch1 gene silencing in MiaPaCa-2 cells, BCPV-siRNAKsiRNAN^tcm nanocomplexes effectively reversed the epithelia-mesenchymaltransition (EMT) in MiaPaCa-2 cells, thereby greatly enhancing the sensitivity ofMiaPaCa-2 cells to GEM. MiaPaCa-2 cell proliferation, migration, and invasionwere effectively inhibited, and cell apoptosis was also significantly enhanced bythe synergistic antitumor effect of BCPV-siRNAK siRNAN^t~l nanocomplexesand GEM. These results suggest that this combination RNAi therapy can be usedto improve cancer cell sensitivity to chemotherapeutic drugs. Specifically, thisnewly develooed strate^v has a great potential for treating pancreatic cancer. | Chengbin Yang Kok Ken Chan Wen-Jen Lin Alana Mauluidy Soehartono Guimiao Lin Huiting Toh Ho Sup Yoon Chih-Kuang Chen Ken-Tye Yong | 2017 | Nano Research2017,10,9: | 3 |
| 3 | Conservation and characterization of unique porcine interstitial telomeric sequences显示文摘Telomeres are composed of TTAGGG repeats and located at the ends of chromosomes. Telomeres protect chromosomes from instability in mammals, including mice and humans. Repetitive TTAGGG sequences are also found at intrachromosomal sites, where they are named as interstitial telomeric sequences (ITSs). Aberrant ITSs are implicated in chromosomal instability and found in cancer cells. Interestingly, in pigs, vertebrate telomere sequences TTAGGG (vITSs) are also localized at the centromeric region of chromosome 6, in addition to the end of all chromosomes. Surprisingly, we found that botanic telomere sequences, TTTAGGG (bITSs), also localize with vITSs at the centromeric regions of pig chromosome 6 using telomere fluorescence in situ hybridization (FISH) and by comparisons between several species. Furthermore, the average lengths of vITSs are highly correlated with those of the terminal telomeres (TTS). Also, pig ITSs show a high incidence of telomere doublets, suggesting that pig ITSs might be unstable and dynamic. Together, our results show that pig cells maintain the conserved telomere sequences that are found at the ITSs from of plants and other vertebrates. Further understanding of the function and regulation of pig ITSs may provide new clues for evolution and chromosomal instability. | JI GuangZhen LIU Kai CHEN ChengBin RUAN WeiMin GLYTSOU Christina YANG Yang OKUKA Maja SONG WenQing GAGOS Sarantis LINing LIU Lin | 2012 | Science China(Life Sciences)2012,55,12: | 1 |

| 5 | Reduction of mercury(Ⅱ)by electrons contained in carbon dots:An environmentally friendly cold vapor generation for mercury analysis显示文摘In this work,the reduction of mercury ions(Hg2+)to elemental mercury(Hg0)was easily achieved using highly reductive carbon dots(r-CDs),which synthesized from sucrose by a simple and cost-effective method.After a careful mechanistic study,the reduction was probably accomplished with the large numbers of electrons contained in r-CDs rather than the oxidation of its functional groups.Additionally,a3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)assay showed that the r-CDs were nontoxic to wildlife and human beings.Consequently,the r-CDs were used as an alternative to toxic reductants(SnCl2 or NaBH4)for the sensitive and in situ determination of mercury by cold vapor gene ration(CVG)coupled to a miniature point discharge optical emission spectrometer(μPD-OES).Limit of detection of 0.05μg/L was obtained for Hg2+,with relative standard deviation(RSD)less than 5.4%at a concentration of 5μg/L.The accuracy of r-CDs induced CVG-μPD-OES was validated by the determination of mercury in a certified reference material(DOLT-5,dogfish liver)and five natural water samples collected from different rivers and lakes in Chengdu City,Since r-CDs are nontoxic and prepared from abundant and inexpensive sucrose,the r-CDs induced CVG-μPD-OES retains the great potential for the inexpensive and enviro nmentally friendly field analysis of mercury in natural water.The accuracy of the proposed method was validated by the analysis of a certified reference material and several water samples with satisfactory results. | Tao Chen Yao Lin Haochen Li Rui Yang Xiandeng Hou Baozhan Zheng Chengbin Zheng | 2020 | Chinese Chemical Letters2020,31,10: | 0 |
| 6 | Hallmark guided identification and characterization of a novel immune-relevant signature for prognostication of recurrence in stageⅠ-Ⅲlung adenocarcinoma显示文摘The high risk of postoperative mortality in lung adenocarcinoma(LUAD)patients is principally driven by cancer recurrence and low response rates to adjuvant treatment.Here,A combined cohort containing 1,026 stageⅠ-Ⅲpatients was divided into the learning(n Z 678)and validation datasets(n Z 348).The former was used to establish a 16-mRNA risk signature for recurrence prediction with multiple statistical algorithms,which was verified in the valida-tion set.Univariate and multivariate analyses confirmed it as an independent indicator for both recurrence-free survival(RFS)and overall survival(OS).Distinct molecular characteristics between the two groups including genomic alterations,and hallmark pathways were compre-hensively analyzed.Remarkably,the classifier was tightly linked to immune infiltrations,high-lighting the critical role of immune surveillance in prolonging survival for LUAD.Moreover,the classifier was a valuable predictor for therapeutic responses in patients,and the low-risk group was more likely to yield clinical benefits from immunotherapy.A transcription factor regulato-ry proteineprotein interaction network(TF-PPI-network)was constructed via weighted gene co-expression network analysis(WGCNA)concerning the hub genes of the signature.The con-structed multidimensional nomogram dramatically increased the predictive accuracy.There-fore,our signature provides a forceful basis for individualized LUAD management with promising potential implications. | Yongqiang Zhang Zhao Yang Yuqin Tang Chengbin Guo Danni Lin d Linling Cheng Xun Hu Kang Zhang Gen Li | 2023 | Genes & Diseases2023,10,4: | 0 |
| 7 | The S100 calcium binding protein A11 promotes liver fibrogenesis by targeting TGF-βsignaling显示文摘Liver fibrosis is a key transformation stage and also a reversible pathological process in various types of chronic liver diseases.However,the pathogenesis of liver fibrosis still remains elusive.Here,we report that the calcium binding protein A11(S100A11)is consistently upregulated in the integrated data from GSE liver fibrosis and tree shrew liver proteomics.S100A11 is also experimentally activated in liver fibrosis in mouse,rat,tree shrew,and human with liver fibrosis.While overexpression of S100A11 in vivo and in vitro exacerbates liver fibrosis,the inhibition of S100A11 improves liver fibrosis.Mechanistically,S100A11 activates hepatic stellate cells(HSCs)and the fibrogenesis process via the regulation of the deacetylation of Smad3 in the TGF-βsignaling pathway.S100A11 physically interacts with SIRT6,a deacetylase of Smad2/3,which may competitively inhibit the interaction between SIRT6 and Smad2/3.The subsequent release and activation of Smad2/3 promote the activation of HSCs and fibrogenesis.Additionally,a significant elevation of S100A11 in serum is observed in clinical patients.Our study uncovers S100A11 as a novel profibrogenic factor in liver fibrosis,which may represent both a potential biomarker and a promising therapy target for treating liver fibrosis and fibrosis-related liver diseases. | Tingting Zhu Linqiang Zhang Chengbin Li Xiaoqiong Tan Jing Liu Huiqin Li Qijing Fan Zhiguo Zhang Mingfeng Zhan Lin Fu Jinbo Luo Jiawei Geng Yingjie Wu Xiaoju Zou Bin Liang | 2022 | Journal of Genetics and Genomics2022,49,4: | 0 |
