| 2 | Two-dimensional speckle tracking echocardiography for the assessment of atrial function显示文摘Echocardiography is the most common diagnostic method for assessing atrial function but the technique has some limitations. Traditionally, assessment of left atrial function has been performed by measuring volumes with 2D echocardiography. Additionally, it can be assessed with transmitral Doppler and pulmonary vein Doppler. Recently, an alternative method has been incorporated, namely, measurement of myocardial deformation with color tissue Doppler-derived strain. However, this method has several limitations, such as suboptimal reproducibility, angle-dependence, signal artifacts and the fact that it only measures regional strain and does not obtain information about the curved portion of the atrial roof. To overcome these limitations in the quantification of atrial function, the use of speckle tracking echocardiography (STE) strain has been proposed. This technique is not derived from Doppler but rather from 2D echocardiography; it is angle-independent and allows one to measure global as well as regional atrial strain. In this editorial, we describe the physical and pathophysiological concepts of STE and underline the clinical usefulness of this new technique. | Tomás Francisco Cianciulli María Cristina Saccheri Jorge Alberto Lax Alejandra Marina Bermann Daniel Ernesto Ferreiro | 2010 | World Journal of Cardiology2010,2,7: | 39 |

| 6 | IDH突变的弥漫性和间变性星形细胞瘤具有相同的发病年龄和极小的生存期差异:一个WHO分级的问题显示文摘WHO(2007)中枢神经系统肿瘤分类中列出WHOⅡ级的弥漫性星形细胞瘤(A Ⅱ WHO 2007)和WHOⅢ级的间变性星形细胞瘤( AA Ⅲ WHO 2007)之间的区别。 A Ⅱ WHO (2007)的患者与AA Ⅲ WHO (2007)的患者相比显著年轻、生存期明显较长。迄今为主,分级和分类仅仅依靠形态学而未考虑IDH这一预后相关分子标记的状态。作者发现,对于IDH突变的星形细胞瘤而言,WHO(2007)的分级系统对预后的提示意义较差。检测来自3个独立的病例系列共1360例成人弥漫性星形细胞肿瘤的年龄分布和生存时间,其中包括683例Ⅱ级IDH突变型星形细胞瘤( A Ⅱ IDHmut)、562例IDH突变型的间变性星形细胞瘤( AA Ⅲ IDHmut)和115例IDH 突变的胶质母细胞瘤( GBM IDHmut )。 A ⅡIDHmut和 AA Ⅲ IDHmut的患者显示具有相同的发病年龄(36~37岁),而两级别之间的生存时间差异小于 WHO (2007)的报道(A Ⅱ IDHmut 中位生存时间为10.9年,AAⅢIDHmut为9.3年)。作者分析提示AⅡWHO2007与AAⅢ WHO2007年龄分布和生存时间的差异主要取决于 IDH非突变型肿瘤所占的比例。这些数据结果对目前实行的星形细胞瘤分级和危险分层提出了重大挑战,并可能对 IDH突变型星形细胞瘤的治疗管理产生深远的影响。 | David E Yasin M Daniel S 李晓玲 王行富 | 2015 | 临床与实验病理学杂志2015,31,7: | 17 |
| 7 | Anterior cruciate ligament reconstruction best practice: A review of graft choice显示文摘There is much literature about differing grafts used in anterior cruciate ligament(ACL) reconstruction. Much of this is of poor quality and of a low evidence base. We review and summarise the literature looking at the four main classes of grafts used in ACL reconstruction; bone-patella tendon-bone, hamstrings, allograft and synthetic grafts. Each graft has the evidence for its use reviewed and then compared, where possible, to the others. We conclude that although there is no clear 'best' graft, there are clear differences between the differing graft choices. Surgeon's need to be aware of the evidence behind these differences, in order to have appropriate discussions with their patients, so as to come to an informed choice of graft type to best suit each individual patient and their requirements. | Daniel A Shaerf Philip S Pastides Khaled M Sarraf Charles A Willis-Owen | 2014 | World Journal of Orthopedics2014,5,1: | 14 |
| 8 | WJSC 6^(th) Anniversary Special Issues(2):Mesenchymal stem cells Progress of mesenchymal stem cell therapy for neural and retinal diseases显示文摘Complex circuitry and limited regenerative power make central nervous system(CNS)disorders the most challenging and difficult for functional repair.With elusive disease mechanisms,traditional surgical and medical interventions merely slow down the progression of the neurodegenerative diseases.However,the number of neurons still diminishes in many patients.Recently,stem cell therapy has been proposed as a viable option.Mesenchymal stem cells(MSCs),a widely-studied human adult stem cell population,have been discovered for more than 20 years.MSCs have been found all over the body and can be conveniently obtained from different accessible tissues:bone marrow,blood,and adipose and dental tissue.MSCs have high proliferative and differentiation abilities,providing an inexhaustible source of neurons and glia for cell replacement therapy.Moreover,MSCs also show neuroprotective effects without any genetic modification or reprogramming.In addition,the extraordinary immunomodulatory properties of MSCs enable autologous and heterologous transplantation.These qualities heighten the clinical applicability of MSCs when dealing with the pathologies of CNS disorders.Here,we summarize the latest progress of MSC experimental research as well as human clinical trials for neural and retinal diseases.This review article will focus on multiple sclerosis,spinal cord injury,autism,glaucoma,retinitis pigmentosa and age-related macular degeneration. | Tsz Kin Ng Veronica R Fortino Daniel Pelaez Herman S Cheung | 2014 | World Journal of Stem Cells2014,6,2: | 13 |
| 9 | Helicobacter pylori and autoimmune disease:Cause or bystander显示文摘Helicobacter pylori(H.pylori)is the main cause of chronic gastritis and a major risk factor for gastric cancer.This pathogen has also been considered a potential trigger of gastric autoimmunity,and in particular of autoimmune gastritis.However,a considerable number of reports have attempted to link H.pylori infection with the development of extra-gastrointestinal autoimmune disorders,affecting organs not immediately relevant to the stomach.This review discusses the current evidence in support or against the role of H.pylori as a potential trigger of autoimmune rheumatic and skin diseases,as well as organ specific autoimmune diseases.We discuss epidemiological,serological,immunological and experimental evidence associating this pathogen with autoimmune diseases.Although over one hundred autoimmune diseases have been investigated in relation to H.pylori,we discuss a select number of papers with a larger literature base,and include Sj grens syndrome,rheumatoid arthritis,systemic lupus erythematosus,vasculitides,autoimmune skin conditions,idiopathic thrombocytopenic purpura,autoimmune thyroid disease,multiple sclerosis,neuromyelitis optica and autoimmune liver diseases.Specific mention is given to those studies reporting an association of anti-H.pylori antibodies with the presence of autoimmune disease-specific clinical parameters,as well as those failing to find such associations.We also provide helpful hints for future research. | Daniel S Smyk Andreas L Koutsoumpas Maria G Myt-ilinaiou Eirini I Rigopoulou Lazaros I Sakkas Dimitrios P Bogdanos | 2014 | World Journal of Gastroenterology2014,20,3: | 12 |
| 10 | Adiponectin as a protective factor in hepatic steatosis显示文摘AIM: Obesityand insulin resistance (IR) are closely related to hepatic steatosis (HS), and adiponectin is a hepatic insulin sensitizer that has important effects in liver function.This study aims at investigating the relationship between serum adiponectin concentration and the presence of HS.METHODS: We carried out a cross-sectional study in a check-up unit of a University Hospital in Mexico City. We enrolled 196 subjects, comprising 98 subjects with HS (27 women, 71 men) and 98 controls (37 women and 61men). Anthropometric, metabolic and biochemical variables were measured in the two groups. Serum adiponectin and leptin concentrations were determined,their association with grade of HS tested, and concentrations,according to quartiles, compared between cases and controls. χ2 analysis for linear trends was used to test for a dose-response relationship and logistic regression analysis was conducted to test for a protective effect of adiponectin.RESULTS: The HS subjects were older and more obese than controls, with a central obesity pattern. In the fourth quartile of adiponectin concentrations, HS was less common and severe. In a multivariate model of the fourth quartile of the adiponectin concentrations, we observed a protective effect (OR = 0.17, 95%CI: 0.04-0.67, P= 0.01).In subjects with more severe HS, we observed higher leptin concentrations, and caloric intakes, total fat and iron consumption were higher than in controls.CONCLUSION: The results of the present study suggest that a high serum concentration of adiponectin is associated with a protective effect against HS. | Nahum Méndez-Sánchez Norberto C.Chávez-Tapia Antonio R.Villa Karla Sánchez-Lara Daniel Zamora-Valdés Martha H.Ramos Misael Uribe | 2005 | World Journal of Gastroenterology2005,11,12: | 12 |
| 11 | The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment. | ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart | 2019 | Science China(Physics,Mechanics & Astronomy)2019,62,2: | 11 |

| 13 | Role of immunosuppression and tumor differentiation in predicting recurrence after liver transplantation for hepatocellular carcinoma: A multicenter study of 412 patients显示文摘AIM: To assess pre-orthotopic liver transplantation (OLT) factors that could be evaluated pre-operatively or con- trolled post-operatively associated with hepatocellular carcinoma (HCC) recurrence and disease-free survival after liver transplantation (LT).METHODS: Four hundred and twelve patients trans- planted for HCC between 1988 and 1998 in 14 French centers, who survived the postoperative period were studied. Kaplan Meier estimates were calculated for 24 variables potentially associated with recurrence of HCC. Uni- and multivariate analyses were conducted to iden- tify independent predictors of recurrence. RESULTS: Overall 5-year disease-free survival was 57.1%. By univariate analysis, variables associated with disease-free survival were: presence of cirrhosis (P = 0.001), etiology of liver disease (P = 0.03), α fetoprotein level (< 200, 200 to 2000, or > 2000; P < 0.0001), γ-GT activity (N, N to 2N or > 2N; P = 0.02), the number of nodules (1, 2-3 or ≥ 4; P = 0.02), maximal diameter of the largest nodule (< 3 cm, 3 to 5 cm or > 5 cm; P < 0.0001), the sum of the diameter of the nodules (< 3 cm, 3 to 5 cm, 5 to 10 cm or >10 cm; P < 0.0001), bi- lobar location (P = 0.01), preoperative portal thrombosis (P < 0.0001), peri-operative treatment of the tumor (P = 0.002) and chemoembolization (P = 0.03), tumor differentiation (P = 0.01), initial type of calcineurin inhibitor (P = 0.003), the use of antilymphocyte antibodies (P = 0.02), rejection episodes (P = 0.003) and period of LT (P < 0.0001). By multivariate analysis, 6 variables were independently associated with HCC recurrence: maximal diameter of the largest nodule (P < 0.0001), time of LT (P < 0.0001), tumor differentiation (P < 0.0001), use of anti-lymphocyte antibody (ATG) or anti-CD3 antibody (OKT3) (P = 0.005), preoperative portal thrombosis (P = 0.06) and the number of nodules (P = 0.06). CONCLUSION: This study identif ies immunosuppression, through the use of ATG or OKT3, as a predictive factor of tumor recurrence, and confi rms the prognostic value of tumor differentiation. | Thomas Decaens Franoise Roudot-Thoraval Solange Bresson-Hadni Carole Meyer Jean Gugenheim Francois Durand Pierre-Henri Bernard Olivier Boillot Philippe Compagnon Yvon Calmus Jean Hardwigsen Christian Ducerf Georges Philippe Pageaux Sébastien Dharancy Olivier Chazouillères Daniel Cherqui Christophe Duvoux | 2006 | World Journal of Gastroenterology2006,12,45: | 10 |
| 14 | Sternoclavicular joint dislocation and its management: A review of the literature显示文摘Dislocations of the sternoclavicular joint(SCJ) occur with relative infrequency and can be classified into anterior and posterior dislocation, with the former being more common. The SCJ is inherently unstable due to its lack of articular contact and therefore relies on stability from surrounding ligamentous structures, such as the costoclavicular, interclavicular and capsular ligaments. The posterior capsule has been shown in several studies to be the most important structure in determining stability irrespective of the direction of injury. Posterior dislocation of the SCJ can be associated with life threatening complications such as neurovascular, tracheal and oesophageal injuries. Due to the high mortality associated with such complications, these injuries need to be recognised acutely and managed promptly. Investigations such as x-ray imaging are poor at delineating anatomy at the level of the mediastinum and therefore CT imaging has become the investigation of choice. Due to its rarity, the current guidance on how to manage acute and chronic dislocations is debatable. This analysis of historical and recent literature aims to determine guidance on current thinking regarding SCJ instability, including the use of the Stanmore triangle. The described methods of reduction for both anterior and posterior dislocations and the various surgical reconstructive techniques are also discussed. | Daniel J Morell David S Thyagarajan | 2016 | World Journal of Orthopedics2016,7,4: | 10 |
| 15 | Potential role of metabolomics in diagnosis and surveillance of gastric cancer显示文摘Gastric cancer is one of the deadliest cancers worldwide, and is especially prevalent in Asian countries. With such high morbidity and mortality, early diagnosis is essential to achieving curative intent treatment and long term survival. Metabolomics is a new field of study that analyzes metabolites from biofluids and tissue samples. While metabolomics is still in its infancy, there are numerous potential applications in oncology, specifically early diagnosis. Only a few studies in the literature have examined metabolomics' role in gastric cancer. Various fatty acid, carbohydrate, nucleic acid, and amino acid metabolites have been identified that distinguish gastric cancer from normal tissue and benign gastric disease. However, findings from these few studies are at times conflicting. Most studies demonstrate some relationship of cancer cells to the Warburg Effect, in that glycolysis predominates with conversion of pyruvate to lactate. This is one of the most consistent findings across the literature. There is less consistency in metabolomic signature with respect to nucleic acids, lipids and amino acids. In spite of this, metabolomics holds some promise for cancer surveillance but further studies are necessary to achieve consistency and validation before it can be widely employed as a clinical tool. | Angela W Chan Richdeep S Gill Daniel Schiller Michael B Sawyer | 2014 | World Journal of Gastroenterology2014,20,36: | 9 |
| 16 | In vivo radiometric analysis of glucose uptake and distribution in mouse bone显示文摘Bone formation and remodeling occurs throughout life and requires the sustained activity of osteoblasts and osteoclasts,particularly during periods of rapid bone growth.Despite increasing evidence linking bone cell activity to global energy homeostasis,little is known about the relative energy requirements or substrate utilization of bone cells.In these studies,we measured the uptake and distribution of glucose in the skeleton in vivo using positron-emitting^(18)F-fluorodeoxyglucose([^(18)F]-FDG) and non-invasive,high-resolution positron emission tomography/computed tomography(PET/CT) imaging and ex vivo autoradiography.Assessment of [^(18)F]-FDG uptake demonstrated that relative to other tissues bone accumulated a significant fraction of the total dose of the glucose analog.Skeletal accumulation was greatest in young mice undergoing the rapid bone formation that characterizes early development.PET/CT imaging revealed that [^(18)F]-FDG uptake was greatest in the epiphyseal and metaphyseal regions of long bones,which accords with the increased osteoblast numbers and activity at this skeletal site.Insulin administration significantly increased skeletal accumulation of [^(18)F]-FDG,while uptake was reduced in mice lacking the insulin receptor specifically in osteoblasts or fed a high-fat diet.Our results indicated that the skeleton is a site of significant glucose uptake and that its consumption by bone cells is subject to regulation by insulin and disturbances in whole-body metabolism. | Meredith L Zoch Diane S Abou Thomas L Clemens Daniel LJ Thorek Ryan C Riddle | 2016 | Bone Research2016,4,1: | 9 |

| 18 | Concordance of non-invasive mechanical and serum tests for liver fibrosis evaluation in chronic hepatitis C显示文摘AIM To determine the sensitivity and specificity of liver stiffness measurement(LSM) and serum markers(SM) for liver fibrosis evaluation in chronic hepatitis C.METHODS Between 2012 and 2014,81 consecutive hepatitis C virus(HCV) patients had METAVIR score from liver biopsy compared with concurrent results from LSM [transient elastography(TE) [FibroS can~/ARFI technology(Virtual Touch~)] and SM [FIB-4/aspartate aminotransferase-toplatelet ratio index(APRI)].The diagnostic performance of these tests was assessed using receiver operating characteristic curves.The optimal cut-off levels of each test were chosen to define fibrosis stages F ≥ 2,F ≥ 3 and F = 4.The Kappa index set the concordance analysis.RESULTS Fifty point six percent were female and the median age was 51 years(30-78).Fifty-six patients(70%) weretreatment-na?ve.The optimal cut-off values for predicting F ≥ 2 stage fibrosis assessed by TE were 6.6 kP a,for acoustic radiation force impulse(ARFI) 1.22 m/s,for APRI 0.75 and for FIB-4 1.47.For F ≥ 3 TE was 8.9 kP a,ARFI was 1.48 m/s,APRI was 0.75,and FIB-4 was 2.For F = 4,TE was 12.2 kP a,ARFI was 1.77 m/s,APRI was 1.46,and FIB-4 was 3.91.The APRI could not distinguish between F2 and F3,P = 0.92.The negative predictive value for F = 4 for TE and ARFI was 100%.Kappa index values for F ≥ 3 METAVIR score for TE,ARFI and FIB-4 were 0.687,0.606 and 0.654,respectively.This demonstrates strong concordance between all three screening methods,and moderate to strong concordance between them and APRI(Kappa index = 0.507).CONCLUSION Given the costs and accessibility of LSM methods,and the similarity with the outcomes of SM,we suggest that FIB-4 as well as TE and ARFI may be useful indicators of the degree of liver fibrosis.This is of particular importance to developing countries. | Denise C Paranaguá-Vezozzo Adriana Andrade Daniel F C Mazo Vinicius Nunes Ana L Guedes Taisa G Ragazzo Renata Moutinho Lucas S Nacif Suzane K Ono Venancio A F Alves Flair J Carrilho | 2017 | World Journal of Hepatology2017,9,8: | 7 |
| 19 | Clinical implication of 14-3-3 epsilon expression in gastric cancer显示文摘AIM:To evaluate for the first time the protein and mRNA expression of 14-3-3εin gastric carcinogenesis.METHODS:14-3-3εprotein expression was determined by western blotting,and mRNA expression was examined by real-time quantitative RT-PCR in gastric tumors and their matched non-neoplastic gastric tissue samples.RESULTS:Authors observed a significant reduction of 14-3-3εprotein expression in gastric cancer(GC)samples compared to their matched non-neoplastic tissue.Reduced levels of 14-3-3εwere also associated with diffuse-type GC and early-onset of this pathology.Our data suggest that reduced 14-3-3εmay have a role in gastric carcinogenesis process.CONCLUSION:Our results reveal that the reduced 14-3-3εexpression in GC and investigation of 14-3-3ε interaction partners may help to elucidate the carcino-genesis process. | Mariana Ferreira Leal Danielle Queiroz Calcagno Smia Demachki Paulo Pimentel Assumpo Roger Chammas Rommel Rodríguez Burbano Marília de Arruda Cardoso Smith | 2012 | World Journal of Gastroenterology2012,18,13: | 6 |
| 20 | c-Fos overexpression increases the proliferation of human hepatocytes by stabilizing nuclear Cyclin D1显示文摘AIM: To investigate the effect of stable c-Fos overexpression on immortalized human hepatocyte (IHH) proliferation. METHODS: IHHs stably transfected with c-Fos (IHH-Fos) or an empty vector (IHH-C) were grown in medium supplemented with 1% serum or stimulated with 10% serum. Cell proliferation was assessed by cell counts, 3H-thymidine uptake and fl ow cytometry analyses. The levels of cell cycle regulatory proteins (Cyclin D1, E, A) cyclin dependent kinases (cdk) cdk2, cdk4, cdk6, and their inhibitors p15, p16, p21, p27, to- tal and phosphorylated GSK-3β and epidermal growth factor receptor (EGF-R) were assayed by Western blot- ting. Analysis of Cyclin D1 mRNA levels was performed by reverse transcription-polymerase chain reaction and real-time polymerase chain reaction (PCR) analysis. Stability of Cyclin D1 was studied by cycloheximide blockade experiments. RESULTS: Stable c-Fos overexpression increased cell proliferation under low serum conditions and resulted in a two-fold increase in [3H]-thymidine incorpora- tion following serum addition. Cell cycle analysis by fl ow cytometry showed that c-Fos accelerated the cell cycle kinetics. Following serum stimulation, Cyclin D1 was more abundantly expressed in c-Fos overexpressing cells. Cyclin D1 accumulation did not result from increased transcriptional activation, but from nuclear stabilization. Overexpression of c-Fos correlated with higher nuclear levels of inactive phosphorylated GSK- 3β, a kinase involved in Cyclin D1 degradation and higher levels of EGF-R mRNA, and EGF-R protein compared to IHH-C both in serum starved, and in serum stimulated cells. Abrogation of EGF-R signalling in IHH- Fos by treatment with AG1478, a specif ic EGF-R tyrosine kinase inhibitor, prevented the phosphorylation of GSK-3β induced by serum stimulation and decreased Cyclin D1 stability in the nucleus. CONCLUSION: Our results clearly indicate a positive role for c-Fos in cell cycle regulation in hepatocytes. Importantly, we delineate a new mechanism by which c-Fos could contribute to hepatocarcinogenesis through stabilization of Cyclin D1 within the nucleus, evoking a new feature to c-Fos implication in hepatocellular carcinoma. | Meryem Güller Kahina Toualbi-Abed Agnès Legrand Laurence Michel Alain Mauviel Dominique Bernuau Fanny Daniel | 2008 | World Journal of Gastroenterology2008,14,41: | 6 |
