3Genetic diversity of the hepatitis C virus: Impact and issues inthe antiviral therapy显示文摘The hepatitis C Virus (HCV) presents a high degree of genetic variability which is explained by the combination of a lack of proof reading by the RNA dependant RNA polymerase and a high level of viral replication. The re- sulting genetic polymorphism defines a classification in clades, genotypes, subtypes, isolates and quasispecies. This diversity is known to reflect the range of responses to Interferon therapy. The genotype is one of the pre- dictive parameters currently used to define the antiviral treatment strategy and the chance of therapeutic suc- cess. Studies have also reported the potential impact of the viral genetic polymorphism in the outcome of antivi- ral therapy in patients infected by the same HCV geno- type. Both structural and non structural genomic regions of HCV have been suggested to be involved in the Inter- feron pathway and the resistance to antiviral therapy. In this review, we first detail the viral basis of HCV diversity. Then, the HCV genetic regions that may be implicated in resistance to therapy are described, with a focus on the structural region encoded by the E2 gene and the non- structural genes NS3, NS5A and NS5B. Both mechanisms of the Interferon resistance and of the new antiviral drugs are described in this review.H Le Guillou-Guillemette S Vallet C Gaudy-Graffin C Payan A Pivert A Goudeau F Lunel-Fabiani 2007World Journal of Gastroenterology2007,13,17:6
4Second-look surgery plus hyperthermic intraperitoneal chemotherapy for patients with colorectal cancer at high risk of peritoneal carcinomatosis:Does it really save lives?显示文摘The treatment of peritoneal carcinomatosis (PC) of colorectal origin with cytoreductive surgery(CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) has a 5-year recurrence-free or cure rate of at least 16%, so it is no longer labeled as a fatal disease, and offers prolonged survival for patients with a low peritoneal carcinomatosis index. Metachronous PC of colorectal origin is so predictable that there is a model which has been used to successfully determine the individual risk of each patient. Patients at risk are clearly identified; those with the highest risk have small peritoneal nodules present in the first surgery (70% probability of developing PC), ovarian metastases(60%), perforated tumor onset or intraoperative tumor rupture(50%). Current clinical, biological and imaging techniques still lack sufficient sensitivity to diagnose PC in its initial stages, when CRS plus HIPEC has a greater impact and a higher cure rate. Second-look surgery with HIPEC or prophylactic HIPEC at the time of the first intervention have been proposed as means of preventing and/or anticipating clinical or radiological relapse in at-risk patients. Both techniques have shown a significant decrease in peritoneal relapses and should be considered essential weapons in the management of colorectal cancer.Delia Cortes-Guiral Dominique Elias Pedro Antonio Cascales-Campos Alfredo Badía Yébenes Ismael Guijo Castellano Ana Isabel León Carbonero JoséIgnacio Martín Valadés Jesus Garcia-Foncillas Damian Garcia-Olmo 2017World Journal of Gastroenterology2017,23,3:3
5Tumor cells educate mesenchymal stromal cells to release chemoprotective and immunomodulatory factors显示文摘Factors released by surrounding cells such as cancer-associated mesenchymal stromal cells(CA-MSCs)are involved in tumor progression and chemoresistance.In this study,we characterize the mechanisms by which naYve mesenchymal stromal cells(MSCs)can acquire a CA-MSCs phenotype.Ovarian tumor cells trigger the transformation of MSCs to CA-MSCs by expressing pro-tumoral genes implicated in the chemoresistance of cancer cells,resulting in the secretion of high levels of CXC chemokine receptors 1 and 2(CXCR1/2)ligands such as chemokine(C-X-C motif)ligand 1(CXCL1),CXCL2,and interleukin 8(IL-8).CXCR1/2 ligands can also inhibit the immune response against ovarian tumor cells.Indeed,through their released factors,CA-MSCs promote the differentiation of monocytes towards M2 macrophages,which favors tumor progression.When CXCR1/2 receptors are inhibited,these CA-MSC-activated macrophages lose their M2 properties and acquire an anti-tumoral phenotype.Both ex vivo and in vivo,we used a CXCR1/2 inhibitor to sensitize ovarian tumor cells to carboplatin and circumvent the pro-tumoral effects of CA-MSCs.Since high concentrations of CXCR1/2 ligands in patients*blood are associated with chemoresistance,CXCR1/2 inhibition could be a potential therapeutic strategy to revert carboplatin resistance.Augustin Le Naour Melissa Prat Benolt Thibault Renaud Mével Léa Lemaitre Helene Leray Marie-Veronique Joubert Kimberley Coulson Muriel Golzio Lise Lefevre Eliane Mery Alejandra Martinez Gwénael Ferron Jean-Pierre Delord Agnès Coste Bettina Couderc 2020Journal of Molecular Cell Biology2020,12,3:3

8Competition between fusion-evaporation and multifragmentation in central collisions in ^(58)Ni+^(48)Ca at 25A MeV显示文摘The experimental data concerning the58Ni+48Ca reaction at Elab(Ni)=25A MeV,collected by using the CHIMERA 4π device,have been analyzed in order to investigate the competition among different reaction mechanisms for central collisions in the Fermi energy domain.As a main criterion for centrality selection we have chosen the flow angle(flow) method,making an event-by-event analysis that considers the shape of events,as it is determined by the eigenvectors of the experimental kinetic-energy tensor.For the selected central events(flow >60°) some global variables,good to characterize the pattern of central collisions have been constructed.The main features of the reaction products were explored by using different constraints on some of the relevant observables,like mass and velocity distributions and their correlations.Much emphasis was devoted,for central collisions,to the competition between fusion-evaporation processes with subsequent identification of a heavy residue and a possible multifragmentation mechanism of a well defined(if any) transient nuclear system.Dynamical evolution of the system and pre-equilibrium emission were taken into account by simulating the reactions in the framework of transport theories.Different approaches have been envisaged(dynamical stochastic BNV calculations + sequential SIMON code,QMD,CoMD,etc.).Preliminary comparison of the experimental data with BNV calculations shows reasonable agreement with the assumption of sequential multifragmentation emission in the mass region of IMFs close to the heavy residues.Possible deviations from sequential processes were found for those IMFs in the region of masses intermediate between the mass of heavy residues and the mass of light IMFs.Further simulations are in progress.The experimental analysis will be enriched also by information obtained inspecting the IMF-IMF correlation function,in order to elucidated the nature of space-time decay property of the emitting source associated with events having the largest IMF multiplicity.FRANCALANZA L ABBONDANNO U AMORINI F BARLINI S BINI M BOUGAULT R BRUNO M CARDELLA G CASINI G AGOSTINO M D' De FILIPPO V De SANCTIS J GERACI E GIUSSANI A GRAMEGNA F GUIOT B KRAVCHUK V La GUIDARA E LANZALONE G Le NEINDRE N MAIOLINO C MARINI P MORELLI L OLMI A PAGANO A PAPA M PIANTELLI S PIRRONE S POLITI G POGGI G PORTO F RUSSOTTO P RIZZO F VANNINI G VANNUCCI L 2013Nuclear Science and Techniques2013,24,5:2
