| 1 | Mitochondrial protection by low doses of insulin-like growth factor-Ⅰin experimental cirrhosis显示文摘AIM: To characterize the mitochondrial dysfunction in experimental cirrhosis and to study whether insulin-like growth factor-Ⅰ(IGF-Ⅰ) therapy (4 wk) is able to induce beneficial effects on damaged mitochondria leading to cellular protection. METHODS: Wistar rats were divided into three groups: Control group, untreated cirrhotic rats and cirrhotic rats treated with IGF-Ⅰtreatment (2 μg/100 g bw/d). Mitochondrial function was analyzed by flow cytometry in isolated hepatic mitochondria, caspase 3 activation was assessed by Western blot and apoptosis by TUNEL in the three experimental groups. RESULTS: Untreated cirrhotic rats showed a mitochon- drial dysfunction characterized by a significant reduction of mitochondrial membrane potential (in status 4 and 3); an increase of intramitochondrial reactive oxigen species (ROS) generation and a significant reduction of ATPase activity. IGF-Ⅰtherapy normalized mitochondrial func-tion by increasing the membrane potential and ATPase activity and reducing the intramitochondrial free radical production. Activity of the electron transport complexes Ⅰand Ⅲ was increased in both cirrhotic groups. In addition, untreated cirrhotic rats showed an increase of caspase 3 activation and apoptosis. IGF-Ⅰtherapy reduced the expression of the active peptide of caspase 3 and resulted in reduced apoptosis. | Raquel Pérez María García-Fernández Matías Díaz-Sánchez Juan E Puche Gloria Delgado Marian Conchillo Jordi Muntané Inma Castilla-Cortázar | 2008 | World Journal of Gastroenterology2008，14，17： | 11 |
| 2 | Soluble ST2:A new and promising activity marker in ulcerative colitis显示文摘AIM:To correlate circulating soluble ST2(sST2) levels with the severity of ulcerative colitis(UC) and serum levels of pro-inflammatory cytokines,and to demonstrate the predictive power of sST2 levels for differentiation between active and inactive UC.METHODS:We recruited 153 patients:82 with UC,26 with Crohn's disease(CD) and 43 disease controls [non-inflammatory bowel disease(IBD)].Subjects were excluded if they had diagnosis of asthma,autoimmune diseases or hypertension.The serum levels of sST2 and pro-inflammatory cytokines [pg/mL;median(25th-75th)] as well as clinical features,endoscopic and histological features,were subjected to analyses.The sST2 performance for discrimination between active and inactive UC,non-IBD and healthy controls(HC) was determined with regard to sensitivity and specificity,and Spearman's rank correlation coefficient(r).To validate the method,the area under the curve(AUC) of receiver-operator characteristic(ROC) was determined(AUC,95% CI) and the total ST2 content of the colonic mucosa in UC patients was correlated with circulating levels of sST2.RESULTS:The serum sST2 value was significantly higher in patients with active [235.80(90.65-367.90) pg/mL] rather than inactive UC [33.19(20.04-65.32) pg/mL],based on clinical,endoscopic and histopathological characteristics,as well as compared with non-IBD and HC(P < 0.001).The median level of sST2 in CD patients was 54.17(35.02-122.0) pg/mL,significantly higher than that of the HC group only(P < 0.01).The cutoff was set at 74.87 pg/mL to compare active with inactive UC in a multicenter cohort of patients.Values of sensitivity,specificity,and ability to correctly classify UC,according to activity,were 83.33%,83.33% and 83.33%,respectively.The AUC of the ROC curve to assess the ability of this molecule to discriminate between active vs inactive UC was 0.92(0.86-0.97,P < 0.0001).The serum levels of sST2 in patients with UC significantly correlated with endoscopic and histo-pathological scores(r = 0.76 and r = 0.67,P < 0.0001,respectively),and with the pro-inflammatory cytokine,tumor necrosis factor-α(r = 0.69 and r = 0.61,respectively,P < 0.0001).Interestingly,we found a direct correlation between total intestinal ST2 content and serum levels of sST2,adjusted to endoscopic activity score in patients with mild(r = 0.44,P = 0.004),moderate(r = 0.59,P = 0.002) and severe disease(r = 0.82,P = 0.002).Only patients with inactive UC showed no significant correlation(r = 0.45,P = 0.267).CONCLUSION:sST2 levels correlated with disease severity and inflammatory cytokines,are able to differentiate active from inactive UC and might have a role as a biomarker. | David Díaz-Jiménez Lucía E Núez Caroll J Beltrán Enzo Candia Cristóbal Suazo Manuel varez-Lobos María-Julieta González Marcela A Hermoso Rodrigo Quera | 2011 | World Journal of Gastroenterology2011，17，17： | 8 |
| 3 | Viral hepatitis update: Progress and perspectives显示文摘Viral hepatitis,secondary to infection with hepatitis A,B,C,D,and E viruses,are a major public health problem and an important cause of morbidity and mortality.Despite the huge medical advances achieved in recent years,there are still points of conflict concerning the pathogenesis,immune response,development of new and more effective vaccines,therapies,and treatment.This review focuses on the most important research topics that deal with issues that are currently being solved,those that remain to be solved,and future research directions.For hepatitis A virus we will address epidemiology,molecular surveillance,new susceptible populations as well as environmental and food detections.In the case of hepatitis B virus,we will discuss host factors related to disease,diagnosis,therapy,and vaccine improvement.On hepatitis C virus,we will focus on pathogenesis,immune response,direct action antivirals treatment in the context of solid organ transplantation,issues related to hepatocellular carcinoma development,direct action antivirals resistance due to selection of resistanceassociated variants,and vaccination.Regarding hepatitis D virus,we describe diagnostic methodology,pathogenesis,and therapy.Finally,for hepatitis E virus,we will address epidemiology(including new emerging species),diagnosis,clinical aspects,treatment,the development of a vaccine,and environmental surveillance. | María B Pisano Cecilia G Giadans Diego M Flichman Viviana E Ré María V Preciado Pamela Valva | 2021 | World Journal of Gastroenterology2021，27，26： | 8 |
| 4 | Liver disease and erythropoietic protoporphyria:A concise review显示文摘The porphyries are a group of metabolic disorders characterized by deficiencies in the activity of enzymes involved in the biosynthesis of heme.In erythropoietic protoporphyria(EPP),in the majority of cases an autosomal dominant disease,there is a mutation of the gene that encodes ferrochelatase(FECH).FECH deficiency is associated with increased concentrations of protoporphyrin in erythrocytes,plasma,skin and liver.The prevalence of this inherited disorder oscillates between 1:75 000 and 1:200 000.Clinical manifestations of EPP appear in early infancy upon first exposure to the sun.Nevertheless,approximately 5%-20% of patients with EPP develop liver manifestations.Retention of protoporphyrin in the liver is associated with cholestatic phenomena and oxidative stress that predisposes to hepatobiliary disease of varying degrees of severity,such as cholelithiasis,mild parenchymal liver disease,progressive hepatocellular disease with end-stage liver disease and acute liver failure.Liver damage is the major risk in EPP patients,so surveillance and frequent clinical and biochemical liver follow-up is mandatory.The diagnostic approach consists in detecting increased levels of protoporphyrin,decreased activity of FECH and genetic analysis of the FECH gene.A variety of nonsurgical therapeutic approaches have been adopted for the management of EPP associated with liver disease,but none of these has been shown to be unequivocally efficacious.Nevertheless,some may have a place in preparing patients for liver transplantation.Liver transplantation does not correct the constitutional deficiency of FECH.Consequently,there is a risk of recurrence of liver disease after liver transplantation as a result of continuing overproduction of protoporphyrin.Some authors recommend that bone marrow transplantation should be considered in liver allograft recipients to prevent recurrence of hepatic disease. | María José Casanova-González María Trapero-Marugán E Anthony Jones Ricardo Moreno-Otero | 2010 | World Journal of Gastroenterology2010，16，36： | 7 |
| 5 | Glycoprotein biomarkers for the detection of pancreatic ductal adenocarcinoma显示文摘Pancreatic cancer(Pa C) shows a clear tendency to increase in the next years and therefore represents an important health and social challenge. Currently, there is an important need to find biomarkers for PaC early detection because the existing ones are not useful for that purpose. Recent studies have indicated that there is a large window of time for PaC early detection, which opens the possibility to find early biomarkers that could greatly improve the dismal prognosis of this tumor. The present manuscript reviews the state of the art of the existing PaC biomarkers. It focuses on the anomalous glycosylation process and its role in PaC. Glycan structures of glycoconjugates such as glycoproteins are modified in tumors and these modifications can be detected in biological fluids of the cancer patients. Several studies have found serum glycoproteins with altered glycan chains in PaC patients, but they have not shown enough specificity for PaC. To find more specific cancer glycoproteins we propose to analyze the glycan moieties of a battery of glycoproteins that have been reported to increase in PaC tissues and that can also be found in serum. The combination of these new candidate glycoproteins with their aberrant glycosylation together with the existing biomarkers could result in a panel, which would expect to give better results as a new tool for early diagnosis of PaC and to monitor the disease. | Esther Llop Pedro E Guerrero AdriàDuran Sílvia Barrabés Anna Massaguer María JoséFerri Maite Albiol-Quer Rafael de Llorens Rosa Peracaula | 2018 | World Journal of Gastroenterology2018，24，24： | 4 |
| 6 | Epigenetic basis of Alzheimer disease显示文摘Alzheimer disease(AD)is the primary form of dementia that occurs spontaneously in older adults.Interestingly,the epigenetic profile of the cells forming the central nervous system changes during aging and may contribute to the progression of some neurodegenerative diseases such as AD.In this review,we present general insights into relevant epigenetic mechanisms and their relationship with aging and AD.The data suggest that some epigenetic changes during aging could be utilized as biomarkers and target molecules for the prevention and control of AD. | Angeles C Tecalco-Cruz JosuéO Ramírez-Jarquín María E Alvarez-Sánchez Jesus Zepeda-Cervantes | 2020 | World Journal of Biological Chemistry2020，11，2： | 4 |
| 7 | Celiac disease serology in patients with different pretest probabilities: Is biopsy avoidable?显示文摘AIM: To establish the diagnostic performance of sev-eral serological tests, individually and in combination, for diagnosing celiac disease (CD) in patients with different pretest probabilities, and to explore potential se- rological algorithms to reduce the necessity for biopsy. METHODS: We prospectively performed duodenal biopsy and serology in 679 adults who had either high risk (n = 161) or low risk (n = 518) for CD. Blood samples were tested using six assays (enzyme-linked immunosorbent assay) that detected antibodies to tissue transglutaminase (tTG) and deamidated gliadin peptide (DGP). RESULTS: CD prevalence was 39.1% in the high-risk population and 3.3% in the low-risk group. In high-risk patients, all individual assays had a high diagnostic efficacy [area under receiving operator characteristic curves (AU ROC): 0.968 to 0.999]. In contrast, assays had a lower diagnostic efficacy (AU ROC: 0.835 to 0.972) in the low-risk group. Using assay combinations, it would be possible to reach or rule out diagnosis of CD without biopsy in 92% of cases in both pretest populations. We observed that the new DGP/tTG Screen assay resulted in a surplus compared to more conventional assays in any clinical situation. CONCLUSION: The DGP/tTG Screen assay could be considered as the best initial test for CD. Combinations of two tests, including a DGP/tTG Screen, might be able to diagnose CD accurately in different clinical scenarios making biopsy avoidable in a high proportion of subjects. | Emilia Sugai María L Moreno Hui J Hwang Ana Cabanne Adriana Crivelli Fabio Nach-man Horacio Vázquez Sonia Niveloni Julio Argonz Roberto Mazure Graciela La Motta María E Caniggia Edgardo Smecuol Néstor Chopita Juan C Gómez Eduardo Maurińo Julio C Bai | 2010 | World Journal of Gastroenterology2010，16，25： | 4 |
| 8 | Regression of cardiovascular remodeling in hypertension:Novel relevant mechanisms显示文摘Asymptomatic organ damage due to progressive kidney damage, cardiac hypertrophy and remodeling put hypertensive patients at high risk for developing heart and renal failure, myocardial infarction and stroke. Current antihypertensive treatment normalizes high blood pressure, partially reverses organ damage, and reduces the incidence of heart and renal failure. Activation of the renin-angiotensin system(RAS) is a primary mechanism of progressive organ damage and, specifically, a major cause of both renal and cardiovascular fibrosis. Currently, inhibition of the RAS system [mainly with angiotensin I converting enzyme inhibitors or angiotensin II(Ang II) receptor antagonists] is the most effective antihypertensive strategy for normalizing blood pressure and preventing target organ damage. However, residual organ damage and consequently high risk for cardiovascular events and renal failure still persist. Accordingly, in hypertension, it is relevant to develop new therapeutic perspectives, beyond reducing blood pressure to further prevent/reduce target organ damage by acting on pathways that trigger and maintain cardiovascular and renal remodeling. We review here relevant novel mechanisms of target organ damage in hypertension, their role and evidence in prevention/regression of cardiovascular remodeling and their possible clinical impact as well. Specifically, we focus on the signaling pathway Rho A/Rho kinase, on the impact of the vasodilatory peptides from the RAS and some insights on the role of estrogens and myocardial chymase in cardiovascular hypertensive remodeling. | Jorge E Jalil María P Ocaranza | 2016 | World Journal of Hypertension2016，6，1： | 2 |
