| 2 | HER2 in gastric cancer: Comparative analysis of three different antibodies using whole-tissue sections and tissue microarrays显示文摘AIM:To compare the performance of three commercially available anti-human epidermalgrowth factor receptor 2(HER2)antibodies in whole-tissue sections and tissue microarrays(TMAs)of a series of gastric tumors.METHODS:We present a comparative analysis of three anti-HER2 antibodies(HercepTest,4B5 and SP3)using TMA and whole-tissue sections prepared from the same paraffin blocks of 199 gastric adenocarcinomas operated upon between January 2004 and December2008 at a Brazilian cancer hospital.The data on the patients’age,sex,the anatomical location of the tumor and the Lauren’s histological classification were collected from clinical and pathological records.The immunohistochemical(IHC)results were examined by two pathologists and the cases were classified as positive(3+),equivocal(2+)and negative(0 or 1+),according to the criteria of the IHC scoring system of gastric cancer.TMAs and whole-tissue sections were evaluated separately and independently.All cases yielding discordant IHC results and/or scored as 2+were subjected to dual-color in situ hybridization in order to determine the final HER2 status.Besides determining the sensitivity and predictive value for HER2-positive status,we measured the accuracy of each antibody by calculating the area under the receiver operating characteristic(ROC)curve.The agreement between the results obtained using the TMAs and those obtained using the whole-tissue sections was assessed by means of Kappa coefficient.RESULTS:Intratumoral heterogeneity of HER2 expression was observed with all antibodies.HER2-positive expression(3+)in the whole-tissue sections was observed in 23 cases(11.6%)using the 4B5 antibody,in 18 cases(9.1%)using the SP3 antibody and in 10 cases(5.1%)using the HercepTest antibody.In the TMAs,11 positive cases(5.6%)were identified using SP3 antibody,9(4.6%)using the 4B5 antibody and 6(3%)using the HercepTest antibody.The sensitivity using whole-tissue sections and TMA,respectively,was 95.2%and 42.9%with 4B5,90.5%and 66.7%with SP3 and 47.6%and42.9%with HercepTest.The accuracy,calculated from the area under the ROC curve,using whole-tissue sections and TMA,respectively,was 0.91 and 0.79 by 4B5,0.86 and 0.80 by SP3 and 0.73 and 0.71 by HercepTest.The concordance of the results obtained using wholetissue sections and TMA was 97.4%(Kappa 0.75)using HercepTest,85.6%(Kappa 0.56)using SP3 and 84.1%(Kappa 0.38)using 4B5.CONCLUSION:The use of the 4B5 antibody on wholetissue sections was the most accurate IHC method for evaluating HER2 expression in gastric adenocarcinoma. | Lucas Faria Abraho-Machado Alexandre Andrade dos Anjos Jácome Durval Renato Wohnrath José Sebastio dos Santos Estela Cristina Carneseca José Humberto Tavares Guerreiro Fregnani Cristovam Scapulatempo-Neto | 2013 | World Journal of Gastroenterology2013，19，38： | 12 |
| 3 | Autoimmune hepatitis in childhood: The role of genetic and immune factors显示文摘Autoimmune hepatitis (AIH) is a rare chronic inflammatory disease of the liver, which affects a group of patients who lost their immunological tolerance to antigens of the liver. It is clinically characterized by hypergammaglobulinemia, elevated liver enzymes, presence of autoantibodies and histological changes. Although being rare in children, it represents a serious cause of chronic hepatic disease that can lead to cirrhosis and hepatic failure. Clinical findings, exclusion of more common liver disorders and the detection of antibodies antinuclear antibodies, smooth muscle antibodies and anti-LKM1 are usually enough for diagnosis on clinical practice. The pathogenic mechanisms that lead to AIH remain obscure, but some research findings suggest the participation of immunologic and genetic factors. It is not yet knew the triggering factor or factors that stimulate inflammatory response. Several mechanisms proposed partially explain the immunologic findings of AIH. The knowledge of immune factors evolved might result in better markers of prognosis and response to treatment. In this review, we aim to evaluate the findings of research about genetic and immune markers and their perspectives of application in clinical practice especially in pediatric population. | Priscila Menezes Ferri Liu Débora Marques de Miranda Eleonora Druve Tavares Fagundes Alexandre Rodrigues Ferreira Ana Cristina Simoes e Silva | 2013 | World Journal of Gastroenterology2013，19，28： | 3 |
| 4 | Circulating leptin and its muscle gene expression in Nellore cattle with divergent feed efficiency显示文摘Background: Leptin has a strong relation to important traits in animal production, such as carcass composition,feed intake, and reproduction. It is mainly produced by adipose cells and acts predominantly in the hypothalamus.In this study, circulating leptin and its gene expression in muscle were evaluated in two groups of young Nellore bulls with divergent feed efficiency. Individual dry matter intake(DMI) and average daily gain(ADG) of 98 Nellore bulls were evaluated in feedlot for 70 d to determinate the residual feed intake(RFI) and select 20 animals for the high feed efficient(LRFI) and 20 for the low feed efficient(HRFI) groups. Blood samples were collected on d 56 and at slaughter(80 d) to determine circulating plasma leptin. Samples of Longissimus dorsi were taken at slaughter for leptin gene expression levels.Results: DMI and RFI were different between groups and LRFI animals showed less back fat and rump fat thickness,as well as less pelvic and kidney fat weight. Circulating leptin increased over time in all animals. Plasma leptin was greater in LRFI on 56 d and at slaughter(P = 0.0049). Gene expression of leptin were greater in LRFI animals(P = 0.0022) in accordance with the plasma levels. The animals of the LRFI group were leaner, ate less, and had more circulating leptin and its gene expression.Conclusion: These findings demonstrated that leptin plays its physiological role in young Nellore bulls, probably controlling food intake because feed efficient animals have more leptin and lower residual feed intake. | Lúcio Flávio Macedo Mota Cristina Moreira Bonafé Pamela Almeida Alexandre Miguel Henrique Santana Francisco JoséNovais Erika Toriyama Aldrin Vieira Pires Saulo da Luz Silva Paulo Roberto Leme JoséBento Sterman Ferraz Heidge Fukumasu | 2018 | Journal of Animal Science and Biotechnology2018，9，1： | 3 |
| 5 | Diagnostic criteria for autoimmune hepatitis in children: A challenge for pediatric hepatologists显示文摘Autoimmune hepatitis (AIH) is a progressive inflammatory liver disorder that is rare in children and adolescents. AIH has a broad clinical spectrum and a quick response to treatment with corticosteroids and immunosuppressive medication. The available diagnosis criteria have limitations and should be evaluated in pediatric populations. Recently, some studies reported that the 2008 simplified diagnostic criteria for AIH could be used in children with high sensibility and specificity. In addition, the authors reported that globulin and immunoglobulin G levels can be used interchangeably for diagnostic purposes. They also demonstrated that the 2008 simplified criteria fail in identifying patients with fulminant hepatic failure. Here, we discuss the limitations of the use of these criteria in pediatric patients and the requirement of more studies to improve the diagnosis of AIH in children. | Priscila Menezes Ferri Alexandre Rodrigues Ferreira Débora Marques Miranda Ana Cristina Sim■es e Silva | 2012 | World Journal of Gastroenterology2012，18，33： | 3 |
| 6 | Dendritic cell deficiencies persist seven months after SARS-CoV-2 infection显示文摘Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components.Dendritic cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFN-α).In COVID-19 there is a deficit in DC numbers and IFN-αproduction,which has been associated with disease severity.In this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory markers.Remarkably,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 infection.Moreover,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were observed.These findings contribute to a better understanding of the immunological sequelae of COVID-19. | Alberto Pérez-Gómez Joana Vitallé Carmen Gasca-Capote Alicia Gutierrez-Valencia María Trujillo-Rodriguez Ana Serna-Gallego Esperanza Muñoz-Muela María de los Reyes Jiménez-Leon Mohamed Rafii-El-Idrissi Benhnia Inmaculada Rivas-Jeremias Cesar Sotomayor Cristina Roca-Oporto Nuria Espinosa Carmen Infante-Domínguez Juan Carlos Crespo-Rivas Alberto Fernández-Villar Alexandre Pérez-González Luis Fernando López-Cortés Eva Poveda Ezequiel Ruiz-Mateos JoséMiguel Cisneros Sonsoles Salto-Alejandre Judith Berastegui-Cabrera Pedro Camacho-Martínez Carmen Infante-Domínguez Marta Carretero-Ledesma Juan Carlos Crespo-Rivas Eduardo Márquez JoséManuel Lomas Claudio Bueno Rosario Amaya JoséAntonio Lepe Jerónimo Pachón Elisa Cordero Javier Sánchez-Céspedes Manuela Aguilar-Guisado Almudena Aguilera Clara Aguilera Teresa Aldabo-Pallas Verónica Alfaro-Lara Cristina Amodeo Javier Ampuero María Dolores Avilés Maribel Asensio Bosco Barón-Franco Lydia Barrera-Pulido Rafael Bellido-Alba Máximo Bernabeu-Wittel Candela Caballero-Eraso Macarena Cabrera Enrique Calderón Jesús Carbajal-Guerrero Manuela Cid-Cumplido Yael Corcia-Palomo Juan Delgado Antonio Domínguez-Petit Alejandro Deniz Reginal Dusseck-Brutus Ana Escoresca-Ortega Fátima Espinosa Nuria Espinosa Michelle Espinoza Carmen Ferrándiz-Millón Marta Ferrer Teresa Ferrer Ignacio Gallego-Texeira Rosa Gámez-Mancera Emilio García Horacio García-Delgado Manuel García-Gutiérrez María Luisa Gascón-Castillo Aurora González-Estrada Demetrio González Carmen Gómez-González Rocío González-León Carmen Grande-Cabrerizo Sonia Gutiérrez Carlos Hernández-Quiles Inmaculada Concepción Herrera-Melero Marta Herrero-Romero Luis Jara Carlos Jiménez-Juan Silvia Jiménez-Jorge Mercedes Jiménez-Sánchez Julia Lanseros-Tenllado Carmina López Isabel López Álvaro López-Barrios Luis F.López-Cortés Rafael Luque-Márquez Daniel Macías-García Guillermo Martín-Gutiérrez Luis Martín-Villén JoséMolina Aurora Morillo María Dolores Navarro-Amuedo Dolores Nieto-Martín Francisco Ortega María Paniagua-García Amelia Peña-Rodríguez Esther Pérez Manuel Poyato Julia Praena-Segovia Rafaela Ríos Cristina Roca-Oporto Jesús F.Rodríguez María Jesús Rodríguez-Hernández Santiago Rodríguez-Suárez Ángel Rodríguez-Villodres Nieves Romero-Rodríguez Ricardo Ruiz Zida Ruiz de Azua Celia Salamanca Sonia Sánchez Víctor Manuel Sánchez-Montagut César Sotomayor Alejandro Suárez Benjumea Javier Toral | 2021 | Cellular & Molecular Immunology2021，18，9： | 2 |
| 7 | Medicinal properties of Angelica archangelica root extract: Cytotoxicity in breast cancer cells and its protective effects against in vivo tumor development显示文摘Objective: Although Angelica archangelica is a medicinal and aromatic plant with a long history of use for both medicinal and food purposes, there are no studies regarding the antineoplastic activity of its root.This study aimed to evaluate the cytotoxicity and antitumor effects of the crude extract of A. archangelica root(CEAA) on breast cancer.Methods: The cytotoxicity of CEAA against breast adenocarcinoma cells(4T1 and MCF-7) was evaluated by a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide(MTT) assay. Morphological and biochemical changes were detected by Hoechst 33342/propidium iodide(PI) and annexin V/PI staining. Cytosolic calcium mobilization was evaluated in cells staining with FURA-4 NW. Immunoblotting was used to determine the effect of CEAA on anti-and pro-apoptotic proteins(Bcl-2 and Bax, respectively).The 4 T1 cell-challenged mice were used for in vivo assay.Results: Using ultra-high-performance liquid chromatography–mass spectrometry analysis, angelicin, a constituent of the roots and leaves of A. archangelica, was found to be the major constituent of the CEAA evaluated in this study(73 mg/mL). The CEAA was cytotoxic for both breast cancer cell lines studied but not for human fibroblasts. Treatment of 4 T1 cells with the CEAA increased Bax protein levels accompanied by decreased Bcl-2 expression, in the presence of cleaved caspase-3 and cytosolic calcium mobilization, suggesting mitochondrial involvement in breast cancer cell death induced by the CEAA in this cell line. No changes on the Bcl-2/Bax ratio were observed in CEAA-treated MCF7 cells. Gavage administration of the CEAA(500 mg/kg) to 4T1 cell-challenged mice significantly decreased tumor growth when compared with untreated animals.Conclusion: Altogether, our data show the antitumor potential of the CEAA against breast cancer cells in vitro and in vivo. Further research is necessary to better elucidate the pharmacological application of the CEAA in breast cancer therapy. | Carlos R.Oliveira Daniel G.Spindola Daniel M.Garcia Adolfo Erustes Alexandre Bechara Caroline Palmeira-dos-Santos Soraya S.Smaili Gustavo J.S.Pereira André Hinsberger Ezequiel P.Viriato Maria Cristina Marcucci Alexandra C.H.F.Sawaya Samantha L.Tomaz Elaine G.Rodrigues Claudia Bincoletto | 2019 | Journal of Integrative Medicine2019，17，2： | 2 |
