| 1 | Relationship between angiotensin-(1-7) and angiotensin Ⅱ correlates with hemodynamic changes in human liver cirrhosis显示文摘AIM:To measure circulating angiotensins at different stages ofhuman cirrhosis and to further evaluate a possible relationship between renin angiotensin system (RAS) components and hemodynamic changes.METHODS: Patients were allocated into 4 groups: mild-to-moderate liver disease (MLD), advanced liver disease (ALD), patients undergoing liver transplantation, and healthy controls. Blood was collected to determine plasma renin activity (PRA), angiotensin (Ang) , Ang Ⅱ, and Ang-(1-7) levels using radioimmunoassays. During liver transplantation, hemodynamic parameters were determined and blood was simultaneously obtained from the portal vein and radial artery in order to measure RAS components.RESULTS: PRA and angiotensins were elevated in ALD when compared to MLD and controls (P < 0.05). In contrast, Ang was signicantly reduced in MLD. Ang-(1-7)/Ang Ⅱ ratios were increased in MLD when compared to controls and ALD. During transplantation, Ang Ⅱ levels were lower and Ang-(1-7)/Ang Ⅱ ratios were higher in the splanchnic circulation than in the peripheral circulation (0.52 ± 0.08 vs 0.38 ± 0.04, P < 0.02), whereas the peripheral circulating Ang /Ang ratio was elevated in comparison to splanchnic lev-els (0.18 ± 0.02 vs 0.13 ± 0.02, P < 0.04). Ang-(1-7)/Ang Ⅱ ratios positively correlated with cardiac output (r= 0.66) and negatively correlated with systemic vascular resistance (r =-0.70).CONCLUSION: Our ndings suggest that the relation-ship between Ang-(1-7) and Ang Ⅱmay play a role in the hemodynamic changes ofhuman cirrhosis. | Walkíria Wingester Vilas-Boas Antnio Ribeiro-Oliveira Jr Regina Maria Pereira Renata da Cunha Ribeiro Jerusa Almeida Ana Paula Nadu Ana Cristina Simoes e Silva Robson Augusto Souza dos Santos | 2009 | World Journal of Gastroenterology2009，15，20： | 11 |
| 2 | MGMT and MLH1 methylation in Helicobacter pylori-infected children and adults显示文摘AIM:To evaluate the association between Helicobacter pylori(H.pylori) infection and MLH1 and MGMT methylation and its relationship with microsatellite instability(MSI).METHODS:The methylation status of the MLH1 and MGMT promoter region was analysed by methylation specific methylation-polymerase chain reaction(MSPPCR) in gastric biopsy samples from uninfected or H.pylori-infected children(n = 50),from adults with chronic gastritis(n = 97) and from adults with gastric cancer(n = 92).MLH1 and MGMT mRNA expression were measured by real-time PCR and normalised to a constitutive gene(β actin).MSI analysis was performed by screening MSI markers at 4 loci(Bat-25,Bat-26,D17S250 and D2S123) with PCR;PCR products were analysed by single strand conformation polymorphism followed by silver staining.Statistical analyses were performed with either the χ 2 test with Yates continuity correction or Fisher's exact test,and statistical significance for expression analysis was assessed using an unpaired Student's t-test.RESULTS:Methylation was not detected in the promoter regions of MLH1 and MGMT in gastric biopsy samples from children,regardless of H.pylori infection status.The MGMT promoter was methylated in 51% of chronic gastritis adult patients and was associated with H.pylori infection(P < 0.05);this region was methylated in 66% of gastric cancer patients,and the difference in the percentage of methylated samples between these patients and those from H.pylori-infected chronic gastritis patients was statistically significant(P < 0.05).MLH1 methylation frequencies among H.pylori-infected and non-infected chronic gastritis adult patients were 13% and 7%,respectively.We observed methylation of the MLH1 promoter(39%) and increased MSI levels(68%) in samples from gastric cancer patients in comparison to samples from H.pylori-infected adult chronic gastritis patients(P < 0.001 and P < 0.01,respectively).The frequency of promoter methylation for both genes was higher in gastric cancer samples than in H.pylori-positive chronic gastritis samples(P < 0.05).The levels of MLH1 and MGMT mRNA were significantly reduced in chronic gastritis samples that were also hypermethylated(P < 0.01).CONCLUSION:In summary,MGMT and MLH1 methylation did not occur in earlier-stage H.pylori infections and thus might depend on the duration of infection. | Marisa C Alvarez Juliana C Santos Nathália Maniezzo Marcelo S Ladeira Artur LC da Silva Isabel CA Scaletsky José Pedrazzoli Jr Marcelo L Ribeiro | 2013 | World Journal of Gastroenterology2013，19，20： | 5 |
| 3 | Transcriptome analyses of the Dof-like gene family in grapevine reveal its involvement in berry, flower and seed development显示文摘The Dof(DNA-binding with one finger)protein family spans a group of plant transcription factors involved in the regulation of several functions,such as plant responses to stress,hormones and light,phytochrome signaling and seed germination.Here we describe the Dof-like gene family in grapevine(Vitis vinifera L.),which consists of 25 genes coding for Dof.An extensive in silico characterization of the VviDofL gene family was performed.Additionally,the expression of the entire gene family was assessed in 54 grapevine tissues and organs using an integrated approach with microarray(cv Corvina)and real-time PCR(cv Pinot Noir)analyses.The phylogenetic analysis comparing grapevine sequences with those of Arabidopsis,tomato,poplar and already described Dof genes in other species allowed us to identify several duplicated genes.The diversification of grapevine DofL genes during evolution likely resulted in a broader range of biological roles.Furthermore,distinct expression patterns were identified between samples analyzed,corroborating such hypothesis.Our expression results indicate that several VviDofL genes perform their functional roles mainly during flower,berry and seed development,highlighting their importance for grapevine growth and production.The identification of similar expression profiles between both approaches strongly suggests that these genes have important regulatory roles that are evolutionally conserved between grapevine cvs Corvina and Pinot Noir. | Danielle Costenaro da Silva Vítor da Silveira Falavigna Marianna Fasoli Vanessa Buffon Diogo Denardi Porto Georgios Joannis Pappas Jr Mario Pezzotti Giancarlo Pasquali Luís Fernando Revers | 2016 | Horticulture Research2016，3，1： | 5 |

| 5 | Effect of propranolol on the splanchnic and peripheral renin angiotensin system in cirrhotic patients显示文摘AIM:To evaluate the effect of β-blockade on angiotensins in the splanchnic and peripheral circulation of cirrhotic patients and also to compare hemodynamic parameters during liver transplantation according to propranolol pre-treatment or not. METHODS:Patients were allocated into two groups:outpatients with advanced liver disease(LD) and during liver transplantation(LT). Both groups were subdivided according to treatment with propranolol or not. Plasma was collected through peripheral venipuncture to determine plasma renin activity(PRA),Angiotensin(Ang) Ⅰ,Ang Ⅱ,and Ang-(1-7) levels by radioimmunoassay in LD group. During liver transplantation,hemodynamic parameters were determined and blood samples were obtained from the portal vein to measure renin angiotensin system(RAS) components.RESULTS:PRA,Ang Ⅰ,Ang Ⅱ and Ang-(1-7) were signifi cantly lower in the portal vein and periphery in all subgroups treated with propranolol as compared to non-treated. The relationships between Ang-(1-7) and Ang Ⅰ levels and between Ang Ⅱ and Ang Ⅰ were significantly increased in LD group receiving propranolol. The ratio between Ang-(1-7) and Ang Ⅱ remained unchanged in splanchnic and peripheral circulation in patients under β-blockade,whereas the relationship between Ang Ⅱ and Ang Ⅰ was significantly increased in splanchnic circulation of LT patients treated with propranolol. During liver transplantation,cardiac output and index as well systemic vascular resistance and index were reduced in propranolol-treated subgroup. CONCLUSION:In LD group,propranolol treatment reduced RAS mediators,but did not change the ratio between Ang-(1-7) and Ang Ⅱ in splanchnic and peripheral circulation. Furthermore,the modification of hemodynamic parameters in propranolol treated patients was not associated with changes in the angiotensin ratio. | Walkíria Wingester Vilas-Boas Antnio Ribeiro-Oliveira Jr Renata da Cunha Ribeiro Renata Lúcia Pereira Vieira Jerusa Almeida Ana Paula Nadu Ana Cristina Sim■es e Silva Robson Augusto Souza Santos | 2008 | World Journal of Gastroenterology2008，14，44： | 2 |
| 6 | Interleukin-6-174G/C polymorphism is associated with a decreased risk of type 2 diabetes in patients with chronic hepatitis C virus显示文摘BACKGROUND Chronic hepatitis C(CHC)is associated with type 2 diabetes mellitus.Although the pathogenesis remains to be elucidated,a growing evidence has suggested a role of pro-inflammatory immune response.Increased serum concentrations of Interleukin 6(IL-6)have been associated with insulin resistance,type 2 diabetes mellitus as well as advanced forms of liver disease in chronic hepatitis C infection.AIM To investigate the frequency of IL-6-174G/C(rs1800795)single nucleotide polymorphism(SNP)in CHC patients and in healthy subjects of the same ethnicity.Associations between type 2 diabetes mellitus(dependent variable)and demographic,clinical,nutritional,virological and,IL-6 genotyping data were also investigated in CHC patients.METHODS Two hundred and forty-five patients with CHC and 179 healthy control subjects(blood donors)were prospectively included.Type 2 diabetes mellitus was diagnosed according to the criteria of the American Diabetes Association.Clinical,biochemical,histological and radiological methods were used for the diagnosis of the liver disease.IL-6 polymorphism was evaluated by Taqman SNP genotyping assay.The data were analysed by logistic regression models.RESULTS Type 2 diabetes mellitus,blood hypertension and liver cirrhosis were observed in 20.8%(51/245),40.0%(98/245)and 38.4%(94/245)of the patients,respectively.The frequency of the studied IL-6 SNP did not differ between the CHC patients and controls(P=0.81)and all alleles were in Hardy-Weinberg equilibrium(P=0.38).In the multivariate analysis,type 2 diabetes mellitus was inversely associated with GC and CC genotypes of IL-6-174(OR=0.42;95%CI=0.22-0.78;P=0.006)and positively associated with blood hypertension(OR=5.56;95%CI=2.79-11.09;P<0.001).CONCLUSION This study was the first to show that GC and CC genotypes of IL-6-174 SNP are associated with a decreased risk of type 2 diabetes mellitus in patients chronically infected with hepatitis C virus.The identification of potential inflammatory mediators involved in the crosstalk between hepatitis C virus and the axis pancreas-liver remains important issues that deserve further investigations. | Cliviany Borges da Silva Diego Alves Vieira Luisa Freitas de Melo Anna Luiza Soares Chagas Adriana Dias Gomes César Lúcio Lopes de Faria Jr Rosangela Teixeira Dulciene Maria de Magalh?es Queiroz Gifone Aguiar Rocha Maria Marta Sarquis Soares Juliana Maria Trindade Bezerra Luciana Diniz Silva | 2020 | World Journal of Hepatology2020，12，4： | 2 |
