| 1 | Expression and function of classical protein kinase C isoenzymes in gastric cancer cell line and its drugresistant sublines显示文摘AIM: To investigate the expression and function of classicalprotein kinase C (PKC) isoenzymes in inducing MDRphenotype in gastric cancer cells.METHODS: Two cell lines were used in the study: gastriccancer cell SGC7901 and its drug-resistant cell SGC7901/VCRstepwise-selected by vincristine 0.3, 0. 7 and 1.0 mg@ L-1 ,respectively. The expression of classical PKC (cPKC)isoenzymes in SGC7901 cells and SGC7901/VCR cells weredetected using immunofluorescent cytochemistry, laserconfocal scanning microscope and Wsstern blot. The effectsof anti-PKC isoenzymes antibody of adriamycinaccumulation in SGC7901/VCR cells were determined usingflow cytometric analysis.RESULTS: (1) SGC7901 cells exhibited positive staining ofPKC-α. SGC7901/VCR cells exhibited stronger staining ofPKC-α than SGC7901 cells. The higher dosage vincristineselected, the much stronger staining of PKC-α was observedon SGC7901/VCR cells. (2) Both SGC7901 and SGC7901/VCRcells exhibited positive staining of PKC-βⅠ and PKC-βⅡ withno significant difference. ( 3 ) Compared with SGC7901,SGC7901/VCR cells had decreased adriamycin accumulationand retention. Accumulation of adriamycin in SGC7901 was5.21 + 2.56 mg@ L-1, in SGC7901/VCR 0.3 was 0.85 + 0.29 mg@L-1 , in SGC7901/VCR 0.7 was 0.81 + 0.32 og@ L-1 , and inSGC7901NCR 1.0 was 0.80 + 0.33 mg @ L-1; Retention ofadriamycin in SGC 7901 was 2.51 + 1.23 mg@L-1, in SGC7901/VCR 0.3 was 0.47 + 0.14 mg@ L-1 , in SGC7901/VCR 0.7 was 0.44 + 0.15 mg@ L-1, and in SGC 7901/VCR 1.0 was 0.41 + 0.1 1mg @ L-1 . (4) Fluorescence intensity presented adriamycinaccumulation in SGC7901/VCR cells was increased from 1.14+0.36 to 2.71 +0.94 when cells were co-incubated with anti-PKC-αbut not with anti-PKC-βⅠ, PKC-βⅡ and PKCγ antibodies.CONCLUSION: PKC-α, but not PKC-βⅠ, PKC-βⅡ or PKCγ,may play a role in multidrug resistance of gastric cancercells SGC7901/VCR. | Ying Han Zhe-Yi Han Xin-Min Zhou Ru Shi Yue Zheng Yong-Quan Shi Ji-Yan Miao Bo-Rong Pan Dai-Ming Fan | 2002 | World Journal of Gastroenterology2002，8，3： | 25 |
| 2 | Up-regulation of mitochondrial chaperone TRAP1 in ulcerative colitis associated colorectal cancer显示文摘AIM:To characterize tumor necrosis factor receptorassociated protein 1(TRAP1)expression in the progression of ulcerative colitis(UC)-associated colorectal cancer.METHODS:Chronic UC is an inflammatory bowel disease that predisposes to colorectal cancer.Immunohistochemical analysis was used to evaluate TRAP1expression on tissue microarrays containing colonic tissues from 42 UC progressors(patients with cancer or dysplasia)and 38 non-progressors(dysplasia/cancer free patients).Statistical analyses of the TRAP1immunohistochemistry staining were performed using Graph Pad Prism.Differences in the TRAP1 level between non-progressors and progressors were tested for statistical significance using the Mann-Whitney test.Receiver operating characteristic curve method was used to quantify marker performance in distinguishing diseased cases from controls.RESULTS:TRAP1 was up-regulated in the colon tissues from UC progressors,but not in the colon tissues from UC non-progressors.Moreover,up-regulation of TRAP1 preceded the neoplastic changes:it was present in both the dysplastic and non-dysplastic tissues of UC progressors.When TRAP1 staining in rectal tissue was used as a diagnostic marker,it could distinguish progressors from non-progressors with 59%sensitivity and 80%specificity.Our study further showed that the increase of TRAP1 expression positively correlated with the degree of inflammation in the colorectal cancer tissues,which could be related to the increased oxidation present in the colonic mucosa from UC progressors.We then investigated the cellular proteome changes underlying oxidative stress,and found that oxidative stress could induce up-regulation of TRAP1 along with several other negative modulators of apoptosis.CONCLUSION:These results suggest that oxidative stress in long standing UC could lead to the increase of cytoprotective protein TRAP1,which in turn could promote cancer progression by preventing or protecting the oxidative damaged epithelial cells from undergoing apoptosis.TRAP1 could be a potential diagnostic marker for UC associated colorectal cancer. | Ru Chen Sheng Pan Keith Lai Lisa A Lai David A Crispin Mary P Bronner Teresa A Brentnall | 2014 | World Journal of Gastroenterology2014，20，45： | 9 |
| 3 | BLT1 in dendritic cells promotes Th1/Th17 differentiation and its deficiency ameliorates TNBS-induced colitis显示文摘Leukotriene B4(LTB4)synthesis is enhanced in the colonic mucosa in patients with inflammatory bowel disease(IBD).BLT1,a highaffinity receptor for LTB4,exhibits no effect on the progression of dextran sodium sulfate(DSS)-induced colitis,which mostly relies on innate immunity.Here,we reported that BLT1 regulates trinitrobenzene sulfonic acid(TNBS)-induced colitis,which reflects CD4+T-cell-dependent adaptive immune mechanisms of IBD.We found that BLT1 signaling enhanced the progression of colitis through controlling the production of proinflammatory cytokines by dendritic cells(DCs)and modulating the differentiation of Th1 and Th17.BLT1−/−mice displayed an alleviated severity of TNBS-induced colitis with reduced body weight loss and infiltrating cells in the lamina propria.BLT1 deficiency in DCs led to reduced production of proinflammatory cytokines,including IL-6,TNF-α,and IL-12,and these results were further confirmed via treatment with a BLT1 antagonist.The impaired cytokine production by BLT1−/−DCs subsequently led to reduced Th1 and Th17 differentiation both in vitro and in vivo.We further performed a conditional DC reconstitution experiment to assess whether BLT1 in DCs plays a major role in regulating the pathogenesis of TNBS-induced colitis,and the results indicate that BLT1 deficiency in DCs also significantly reduces disease severity.The mechanistic study demonstrated that BLT1-regulated proinflammatory cytokine production through the Gαiβγsubunit-phospholipase Cβ(PLCβ)-PKC pathway.Notably,we found that treatment with the BLT1 antagonist also reduced the production of proinflammatory cytokines by human peripheral blood DCs.Our findings reveal the critical role of BLT1 in regulating adaptive immunity and TNBS-induced colitis,which further supports BLT1 as a potential drug target for adaptive immunity-mediated IBD. | Jinfeng Zhou Weiming Lai Wanjie Yang Juping Pan Hu Shen Yingying Cai Cuixia Yang Ningjia Ma Yue Zhang Ru Zhang Xin Xie Zhongjun Dong Yuan Gao Changsheng Du | 2018 | Cellular & Molecular Immunology2018，15，12： | 9 |
| 4 | Antibodies against the C-terminal peptide of rabbit oviductin inhibit mouse early embryo development to pass 2-cell stage显示文摘A full-length rabbit oviductin cDNA(1909bp) was cloned. It consists of a 5’-UTR of 52bp, an open reading frame (ORF) of 1374bp and a 3’-UTR of 483bp and has more than 80% homology with that of other mammal oviductins. N-terminal peptide (NTP) (384 residues) and C-terminal peptide (CTP) (73 residues) of deduced protein precursor has about 80% and 50% identity with that of other mammals respectively. Fusion proteins GST-NTP 368(1R-368N)and GST-CTP73 (369F-441A) were expressed and purified. NH2-terminal of CTP sequencing reveals that the purified protein is consistent with the deduced one. In order to study the function of NTP and CTP the mouse anti-NTP and rabbit anti-CTP antisera were prepared. Tissue-specific (skeleton muscle, oviduct, uterus, ovary, liver, heart and brain) analysis indicated that rabbit oviductin was only found in oviduct. The conditioned medium derived from the rabbit oviduct mucosa epithelial cells has a function of overcoming the early embryonic development block of Kunming mous e cultured in vitro. Anti-CTP antiserum could totally inhibit the early embryo development at 2-cell stage cultured in the conditioned culture medium, but anti-NTP antiserum couldn’t. There was a positive relationship between the ratio of early embryos at development block and the dosage of anti-CTP antiserum added in the conditioned culture medium. These results suggest that oviductin has a function not only on fertilization, but also on the release of early embryonic development block, and the later function domain of rabbit oviductin may be situate in its C-terminal. | PAN YONG, ZHENG GU, JIN PING LUO, JUN Ru WANG, JIA KE TSO National Laboratory of Contraceptives and Devices Research, Shanghai Institute of Planned Parenthood Research, 21.40 Xietu Road, Shanghai 200032, China | 2002 | Cell Research2002，12，1： | 8 |
| 5 | Effects of Bushen Yiqi Huoxue Decoction in Treatment of Patients with Diminished Ovarian Reserve:A Randomized Controlled Trial显示文摘Objective:To explore the therapeutic effect of Bushen Yiqi Huoxue Decoction BYHD)in patients with diminished ovarian reserve(DOR).Methods:A total of 180 patients with DOR diagnosed from December2013 to December 2014 were equally assigned into progynova and duphaston(E+D)group,Zuogui Pill group and BYHD group with 60 cases in each by computerized randomization.Patients received E+D,Zuogui Pill or BYHD for 12 months,respectively.Follicle stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E_(2)),anti-Mullerian hormone(AMH),antral follicle count(AFC),ovarian volume,endometrial thickness,and the resistance indices(Rls)of ovarian arteries and uterine arteries were observed before and after treatment.Results:Nine women(4 from the E+D group,3 from the Zuogui Pill group,and 2 from the BYHD group)withdrew from the study.After 6 months,Zuogui Pill and BYHD significantly decreased FSH and LH and increased endometrial thickness and AMH(all P<0.01),BYHD also resulted in E2 elevation(P<0.05),ovary enlargement(P<0.05),AFC increase(P<0.01),and RI of ovarian arteries decrease(P<0.05).After 12 months,further improvements were observed in the Zuogui Pill and BYHD groups(all P<0.01),but BYHD showed better outcomes,with lower FSH,larger ovaries and a thicker endometrium compared with the Zuogui Pill group(all P<0.01).However,E+D only significantly increased endometrial thickness(P<0.01)and no significant improvements were observed in the RI of uterine arteries in the three groups.Conclusions:BYHD had a favorable therapeutic effect in patients with DOR by rebalancing hormone levels,promoting ovulation,and repairing the thin endometrium.The combination of tonifying Shen(Kidney),benefiting qi and activating blood circulation may be a promising therapeutic strategy for DOR. | ZHOU Jing PAN Xin-yao LIN Jin ZHOU Qi LAN Li-kun ZHU Jun DUAN Ru WANG Lan SUN Yan WANG Ling | 2022 | Chinese Journal of Integrative Medicine2022，28，3： | 7 |
| 6 | DDX3X regulates cell survival and cell cycle during mouse early embryonic development显示文摘DDX3X is a highly conserved DEAD-box RNA helicase that participates in RNA transcription,RNA splicing,and mRNA transport,translation,and nucleo-cytoplasmic transport.It is highly expressed in metaphaseⅡ(MⅡ)oocytes and is the predominant DDX3 variant in the ovary and embryo.However,whether it is important in mouse early embryo development remains unknown.In this study,we investigated the function of DDX3X in early embryogenesis by cytoplasmic microinjection with its siRNA in zygotes or single blastomeres of 2-cell embryos.Our results showed that knockdown of Ddx3x in zygote cytoplasm led to dramatically diminished blastocyst formation,reduced cell numbers,and an increase in the number of apoptotic cells in blastocysts.Meanwhile,there was an accumulation of p53 in RNAi blastocysts.In addition,the ratio of cell cycle arrest during 2-cell to 4-cell transition increased following microinjection of Ddx3x siRNA into single blastomeres of 2-cell embryos compared with control.These results suggest that Ddx3x is an essential gene associated with cell survival and cell cycle control in mouse early embryos,and thus plays key roles in normal embryo development. | Qian Li Pan Zhang Chao Zhang Ying Wang Ru Wan Ye Yang Xuejiang Guo Ran Huo Min Lin Zuomin Zhou Jiahao Sha | 2014 | The Journal of Biomedical Research2014，28，4： | 4 |
| 7 | Glycoproteins and glycoproteomics in pancreatic cancer显示文摘Aberrations in protein glycosylation and polysaccharides play a pivotal role in pancreatic tumorigenesis, influencing cancer progression, metastasis, immunoresponse and chemoresistance. Abnormal expression in sugar moieties can impact the function of various glycoproteins, including mucins, surface receptors, adhesive proteins, proteoglycans, as well as their effectors and binding ligands, resulting in an increase in pancreatic cancer invasiveness and a cancerfavored microenvironment. Recent advance in glycoproteomics, glycomics and other chemical biology techniques have been employed to better understand the complex mechanism of glycosylation events and how they orchestrate molecular activities in genomics, proteomics and metabolomics implicated in pancreatic adenocarcinoma. A variety of strategies have been demonstrated targeting protein glycosylation and polysaccharides for diagnostic and therapeutic development. | Sheng Pan Teresa A Brentnall Ru Chen | 2016 | World Journal of Gastroenterology2016，22，42： | 3 |
| 8 | Homoharringtonine is a safe and effective substitute for anthracyclines in children younger than 2 years old with acute myeloid leukemia显示文摘Homoharringtonine (HHT),a plant alkaloid from Cephalotaxus harringtonia,exhibits a unique anticancer mechanism and has been widely used in China to treat patients with acute myeloid leukemia (AML) since the 1970s.Trial SCMC-AML-2009 presented herein was a randomized clinical study designed based on our previous findings that pediatric AML patients younger than two years old may benefit from HHT-containing chemotherapy regimens.Patients randomized to arm A were treated with a standard chemotherapy regimen comprising mainly of anthracyclines and cytarabine (Ara-C),whereas patients in arm B were treated with HHTcontaining regimens in which anthracyclines in all but the initial induction therapy were replaced by HHT.From February 2009 to November 2015,59 patients less than 2 years old with de novo AML (other than acute promyelocytic leukemia) were recruited.A total of 42 patients achieved a morphologic complete remission (CR) after the first course,with similar rates in both arms (70.6% vs.72.0%).At the end of the follow-up period,40 patients remained in CR and 5 patients underwent hematopoietic stem cell transplantation in CR,which could not be considered as events but censors.The 5-year event-free survival (EFS) was 60.2%± 9.6% for arm A and 88.0%± 6.5% for arm B (P=0.024).Patients in arm B experienced shorter durations of leukopenia,neutropenia,and thrombocytopenia and had a lower risk of infection during consolidation chemotherapy with high-dosage Ara-C.Consequently,the homoharringtonine-based regimen achieved excellent EFS and alleviated hematologic toxicity for children aged younger than 2 years with de novo AML compared with the anthracycline-based regimen. | Xiaoxiao Chen Yanjing Tang Jing Chen Ru Chen Longjun Gu Huiliang Xue Ci Pan Jingyan Tang Shuhong Shen | 2019 | Frontiers of Medicine2019，13，3： | 3 |
| 9 | Morphogenesis,Anatomical Observation and Primary Genetic Analysis of a Multi-glume Floral Organ Mutant in Rice显示文摘A multi-glume (mg) mutant was obtained by screening the T-DNA inserted mutant pool. Anatomical observation revealed that the florets of the mutant showed elongated leafy paleas/lemmas and palea/lemma-like structures, just like multi-glumes. Among the 215 observed florets of the mutant, 14.27% were failed to produce pistil and stamens, 23.72% showed extra floret generated on the same rachilla, while 62.01% consisted of one to nine stamens and one to three pistils in a single floret. On the other hand, in some cases the transparent bulged vesile-like tissue could be observed at the basis of filament. The mutant showed glumaceous lodicules, which prevented the florets from opening in natural conditions, while the absolute male and female sterility was an obvious character of the current mutant. Observation on the process of floral organ morphogenesis by a scanning electron microscopy (SEM) indicated that no phenotype difference in floret primordia was found between the wild-type and the mutant. Meanwhile, for the mutant, the beginning of stamen and pistil primordial differentiation was later than the wild type and the palea/lemma-like structure continued to differentiate after the formation of normal palea and lemma. Furthermore, in the mutant the asymmetrical division of floral primordial caused variation in the number of stamens and pistils. Therefore, the genetic analyses indicated that the mutation phenotype was a recessive trait controlled by a single gene and co-segregated with the T-DNA. Based on the phenotypic characteristics, it could be deduced that the mutant was the result of homeotic conversion from the function of the class E genes in ABCD model. | PAN Cun-hong LI Ai-hong Wu Ru ZHANG Ya-fang TANG Wen Wu Chang-yin ZHANG Qi-fa PAN Xue-biao | 2006 | Rice science2006，13，4： | 3 |
| 10 | Biomarkers for colitis-associated colorectal cancer显示文摘Patients with extensive ulcerative colitis(UC) of more than eight years duration have an increased risk of colorectal cancer. Molecular biomarkers for dysplasia and cancer could have a great clinical value in managing cancer risk in these UC patients. Using a wide range of molecular techniques- including cutting-edge OMICS technologies- recent studies have identified clinically relevant biomarker candidates from a variety of biosamples, including colonic biopsies, blood, stool, and urine. While the challenge remains to validate these candidate biomarkers in multi-center studies and with larger patient cohorts, it is certain that accurate biomarkers of colitis-associated neoplasia would improve clinical management of neoplastic risk in UC patients. This review highlights the ongoing avenues of research in biomarker development for colitis-associated colorectal cancer. | Ru Chen Lisa A Lai Teresa A Brentnall Sheng Pan | 2016 | World Journal of Gastroenterology2016，22，35： | 2 |

| 13 | Synthesis and luminescence properties of novel Ce^3+-doped Yb3Al5-xGaxO12 garnets with very fast decay time显示文摘A novel series of Ce^(3+)-doped Yb_3 Al_(5-x)Ga_xO_(12)(x = 0, 1,2, 3,4, 5) powders of ytterbium aluminum gallium garnets were synthesized by high temperature solid-state reaction in a carbon reducing atmosphere. The ytterbium aluminum garnets were characterized by X-ray powder diffraction, UV-Vis diffuse reflectance spectra, photoluminescence spectra and decay curves. Moreover, the substitution effect for the Al^(3+) sites with Ga^(3+) in 0.5 at%Ce:Yb_3 Al_(5-x)Ga_xO_(12)(x = 0,1, 2, 3, 4, 5) garnets were discussed. With the increase of Ga^(3+) ion concentration, the visible absorption peaks within 400-450 nm have blue shift phenomenon,while the absorption peaks in the range of 330-350 nm and the absorption band edge red shifts.Furthermore, the short decay times are very short with less than 10 ns due to the Yb^(3+) + Ce^(3+)→ Yb^(2+) + Ce^(4+) electron transfer reaction. | Ru Li Jie Yin Fei Du Peng Zhang Shangke Pan Jianguo Pan | 2018 | Journal of Rare Earths2018，36，8： | 1 |

| 15 | Diferences and similarities of high-resolution computed tomography features between pneumocystis pneumonia and cytomegalovirus pneumonia in AIDS patients显示文摘Background:Accurately diferentiating pneumocystis from cytomegalovirus pneumonia is crucial for correct therapy selection in AIDS patients.Hence,the goal of this study was to compare the computerized tomography(CT)features of pneumocystis pneumonia and cytomegalovirus pneumonia in AIDS patients and identify clinical hallmarks to accurately distinguish these two pathologies.Methods:A total of 112 AIDS patients(78 with pneumocystis pneumonia and 34 cytomegalovirus pneumonia)at Beijing Ditan Hospital from January 2017 to May 2019 were included in this study.Two experienced chest radiologists retrospectively reviewed CT images for 17 features including ground-glass opacity,consolidation,nodules,and halo sign.Binary logistic regression analyses were conducted to identify the signifcant parameters that distinguished pneumocystis pneumonia from cytomegalovirus pneumonia.Correlations were analyzed by Pearson or Spearman correlation analyses.Result were considered signifcant if P<0.05.Results:The presence of consolidation,halo signs,and nodules(all P<0.05)were signifcantly more frequent in patients with cytomegalovirus pneumonia than in those with pneumocystis pneumonia.Small nodules(32.5%in cytomegalovirus pneumonia,6.41%in pneumocystis pneumonia,P<0.001)without perilymphatic distribution were particularly common in patients with cytomegalovirus pneumonia.Large nodules were not found in any of patients with cytomegalovirus pneumonia.The presence of ground-glass opacity,reticulation,and bronchial wall thickening(all P>0.05)were common in both groups.Conclusions:Analysis of consolidation,nodules,and halo signs may contribute to the diferential diagnosis of pneumocystis pneumonia or cytomegalovirus pneumonia.However,some CT features considered typical in one or other diseases appear with similar frequency in both cohorts of AIDS patients.CT features are potentially useful for the diferential diagnosis of pneumocystis pneumonia and cytomegalovirus pneumonia in AIDS patients. | Chun‑Jing Du Jing‑Yuan Liu Hui Chen Shuo Yan Lin Pu Hao‑Feng Xiong Pan Xiang Chuan‑Sheng Li Ming Zhang Ru‑Ming Xie Bu‑Dong Chen Ang Li | 2020 | Infectious Diseases of Poverty2020，9，5： | 1 |
