| 1 | Diagnostic and prognostic potential of tissue and circulating long non-coding RNAs in colorectal tumors显示文摘Long non-coding RNAs(lncRNAs)are members of the non-protein coding RNA family longer than 200 nucleotides.They participate in the regulation of gene and protein expression influencing apoptosis,cell proliferation and immune responses,thereby playing a critical role in the development and progression of various cancers,including colorectal cancer(CRC).As CRC is one of the most frequently diagnosed malignancies worldwide with high mortality,its screening and early detection are crucial,so the identification of disease-specific biomarkers is necessary.LncRNAs are promising candidates as they are involved in carcinogenesis,and certain lncRNAs(e.g.,CCAT1,CRNDE,CRCAL1-4)show altered expression in adenomas,making them potential early diagnostic markers.In addition to being useful as tissue-specific markers,analysis of circulating lncRNAs(e.g.,CCAT1,CCAT2,BLACAT1,CRNDE,NEAT1,UCA1)in peripheral blood offers the possibility to establish minimally invasive,liquid biopsy-based diagnostic tests.This review article aims to describe the origin,structure,and functions of lncRNAs and to discuss their contribution to CRC development.Moreover,our purpose is to summarise lncRNAs showing altered expression levels during tumor formation in both colon tissue and plasma/serum samples and to demonstrate their clinical implications as diagnostic or prognostic biomarkers for CRC. | Orsolya Galamb Barbara K Barták Alexandra Kalmár Zsófia B Nagy Krisztina A Szigeti Zsolt Tulassay Peter Igaz Béla Molnár | 2019 | World Journal of Gastroenterology2019，25，34： | 18 |
| 2 | Perianal disease,small bowel disease,smoking,prior steroid or early azathioprine/biological therapy are predictors of disease behavior change in patients with Crohn's disease显示文摘AIM:To assess the combined effect of disease phenotype, smoking and medical therapy [steroid, azathioprine(AZA), AZA/biological therapy] on the probability of disease behavior change in a Caucasian cohort of patients with Crohn's disease(CD).METHODS:Three hundred and forty well-characterized, unrelated, consecutive CD patients were analyzed(M/F:155/185, duration:9.4 ± 7.5 years) with a complete clinical follow-up.Medical records including disease phenotype according to the Montreal classification, extraintestinal manifestations, use of medications and surgical events were analyzed retrospectively.Patients were interviewed on their smoking habits at the time of diagnosis and during the regular follow-up visits.RESULTS:A change in disease behavior was observed in 30.8% of patients with an initially non-stricturing, non-penetrating disease behavior after a mean diseaseduration of 9.0 ± 7.2 years.In a logistic regression analysis corrected for disease duration, perianal disease, smoking, steroid use, early AZA or AZA/ biological therapy use were independent predictors of disease behavior change.In a subsequent Kaplan-Meier survival analysis and a proportional Cox regression analysis, disease location(P = 0.001), presence of perianal disease(P < 0.001), prior steroid use(P = 0.006), early AZA(P = 0.005) or AZA/biological therapy(P = 0.002), or smoking(P = 0.032) were independent predictors of disease behavior change.CONCLUSION:Our data suggest that perianal disease, small bowel disease, smoking, prior steroid use, early AZA or AZA/biological therapy are all predictors of disease behavior change in CD patients. | Peter Laszlo Lakatos Zsofia Czegledi Tamas Szamosi Janos Banai Gyula David Ferenc Zsigmond Tunde Pandur Zsuzsanna Erdelyi Orsolya Gemela Janos Papp Laszlo Lakatos | 2009 | World Journal of Gastroenterology2009，15，28： | 14 |
| 3 | Epithelial-to-mesenchymal and mesenchymal-to-epithelial transitions in the colon显示文摘Epithelial-to-mesenchymal and mesenchymal-to-epithelial transitions are well established biological events which have an important role in not just normal tissue and organ development,but in the pathogenesis of diseases.Increasing evidence has established their presence in the human colon during colorectal carcinogenesis and cancer invasion,chronic inflammation-related fibrosis and in the course of mucosal healing.A large body of evidence supports the role for transforming growth factor-β and its downstream Smad signaling,the phosphatidylinositol 3'-kinase/Akt/mTOR axis,the Ras-mitogen-activated protein kinase/Snail/Slug and FOXC2 pathway,and Hedgehog signaling and microRNAs in the development of colorectal cancers via epithelial-to-mesenchymal transition.C-met and Frizzled-7,among others,seem to be the principle effectors of mesenchymal-to-epithelial transition,hence have a role not just in mucosal regeneration but in the progression of colonic wall fibrosis.Here we discuss a role for these pathways in the initiation and development of the transition events.A better understanding of their induction and regulation may lead to the identification of pathways and factors that could be potent therapeutic targets.The inhibition of epithelial-to-mesenchymal transition using mTOR kinase inhibitors targeting the ATP binding pocket and which inhibit both mTORC1 and mTORC2,RNA aptamers or peptide mimetics,such as a Wnt5A-mimetic,may all be useful in both cancer treatment and delaying fibrosis,while the induction of mesenchymal-to-epithelial transition in induced pluripotent stem cells may enhance epithelial healing in the case of severe mucosal damage.The preliminary results of the current studies are promising,but more clinical investigations are needed to develop new and safe therapeutic strategies for diseases of the colon. | Ferenc Sipos Orsolya Galamb | 2012 | World Journal of Gastroenterology2012，18，7： | 13 |
| 4 | Aging related methylation influences the gene expression of key control genes in colorectal cancer and adenoma显示文摘AIM To analyze colorectal carcinogenesis and age-related DNA methylation alterations of gene sequences associated with epigenetic clock CpG sites. METHODS In silico DNA methylation analysis of 353 epigenetic clock Cp G sites published by Steve Horvath was performed using methylation array data for a set of 123 colonic tissue samples [64 colorectal cancer(CRC), 42 adenoma, 17 normal; GEO accession number: GSE48684]. Among the differentially methylated agerelated genes, secreted frizzled related protein 1(SFRP1) promoter methylation was further investigated in colonic tissue from 8 healthy adults, 19 normal children, 20 adenoma and 8 CRC patients using bisulfite-specific PCR followed by methylation-specific high resolution melting(MS-HRM) analysis. m RNA expression of age-related 'epigenetic clock' genes was studied using Affymetrix HGU133 Plus2.0 whole transcriptome data of 153 colonic biopsy samples(49 healthy adult, 49 adenoma, 49 CRC, 6 healthy children)(GEO accession numbers: GSE37364, GSE10714, GSE4183, GSE37267). Whole promoter methylation analysis of genes showing inverse DNA methylationgene expression data was performed on 30 colonic samples using methyl capture sequencing.RESULTS Fifty-seven age-related Cp G sites including hypermethylated PPP1R16 B, SFRP1, SYNE1 and hypomethylated MGP, PIPOX were differentially methylated between CRC and normal tissues(P < 0.05, ?β≥ 10%). In the adenoma vs normal comparison, 70 CpG sites differed significantly, including hypermethylated DKK3, SDC2, SFRP1, SYNE1 and hypomethylated CEMIP, SPATA18(P < 0.05, ?β≥ 10%). In MS-HRM analysis, the SFRP1 promoter region was significantly hypermethylated in CRC(55.0% ± 8.4 %) and adenoma tissue samples(49.9% ± 18.1%) compared to normal adult(5.2% ± 2.7%) and young(2.2% ± 0.7%) colonic tissue(P < 0.0001). DNA methylation of SFRP1 promoter was slightly, but significantly increased in healthy adults compared to normal young samples(P < 0.02). This correlated with significantly increased SFRP1 m RNA levels in children compared to normal adult samples(P < 0.05). In CRC tissue the mR NA expression of 117 agerelated genes were changed, while in adenoma samples 102 genes showed differential expression compared with normal colonic tissue(P < 0.05, logF C > 0.5). The change of expression for several genes including SYNE1, CLEC3 B, LTBP3 and SFRP1, followed the same pattern in aging and carcinogenesis, though not for all genes(e.g., MGP). CONCLUSION Several age-related DNA methylation alterations can be observed during CRC development and progression affecting the m RNA expression of certain CRC- and adenoma-related key control genes. | Orsolya Galamb Alexandra Kalmár Barbara Kinga Barták árpád V Patai Katalin Leiszter Bálint Péterfia Barnabás Wichmann Gábor Valcz Gábor Veres Zsolt Tulassay Béla Molnár | 2016 | World Journal of Gastroenterology2016，22，47： | 7 |
| 5 | Epidemiologic characteristics of Helicobacter pylori infection in southeast Hungary显示文摘BACKGROUND Epidemiologic studies have revealed a decrease in the prevalence of Helicobacter pylori(H.pylori)infection in Western Europe.AIM To obtain data regarding the prevalence of H.pylori in Csongrád and Békés Counties in Hungary,evaluate the differences in its prevalence between urban and rural areas,and establish factors associated with positive seroprevalence.METHODS One-thousand and one healthy blood donors[male/female:501/500,mean age:40(19–65)years]were enrolled in this study.Subjects were tested for H.pylori IgG antibody positivity via enzyme-linked immunosorbent assay.Subgroup analysis by age,gender,smoking habits,alcohol consumption,and urban vs nonurban residence was also performed.RESULTS The overall seropositivity of H.pylori was 32%.It was higher in males(34.93%vs 29.2%,P=0.0521)and in rural areas(36.2%vs 27.94%,P=0.0051).Agricultural/industrial workers were more likely to be positive for infection than office workers(38.35%vs 30.11%,P=0.0095)and rural subjects in Békés County than those in Csongrád County(43.36%vs 33.33%,P=0.0015).CONCLUSION Although the prevalence of H.pylori infection decreased in recent decades in Southeast Hungary,it remains high in middle-aged rural populations.Generally accepted risk factors for H.pylori positivity appeared to be valid for the studied population. | Lenke Bálint Andrea Tiszai Gábor Kozák Ilona Dóczi Veronika Szekeres Orsolya Inczefi Georgina Ollé Krisztina Helle Richárd Róka András Rosztóczy | 2019 | World Journal of Gastroenterology2019，25，42： | 5 |
| 6 | Transhepatic fibrinolysis of mesenteric and portal vein thrombosis in a patient with uIterative colitis: A case report显示文摘AIM: To present a case of acute mesenteric and portal vein thrombosis treated with thrombolytic therapy in a patient with ulcerative colitis in acute phase and to review the literature on thrombolytic therapy of mesenteric-portal system. Treatment of acute portal vein thrombosis has ranged from conservative treatment with thrombolysis and anticoagulation therapy to surgical treatment with thrombectomy and/or intestinal resection.METHODS: We treated our patient with intraportal infusion of plasminogen activator and then heparin through a percutaneous transhepatic catheter.RESULTS: Thrombus resolved despite premature interruption of the thrombolytic treatment for neurological complications, which subsequently resolved.CONCLUSION: Conservative management with plasminogen activator, could be considered as a good treatment for patients with acute porto-mesenteric thrombosis. | Alfredo Guglielmi Francesca Fior Orsolya Halmos Gian Franco Veraldi Lorenzo Rossaro Andrea Ruzzenente Claudio Cordiano | 2005 | World Journal of Gastroenterology2005，11，13： | 3 |

| 9 | mRNA expression, functional profiling and multivariate classification of colon biopsy specimen by cDNA overall glass microarray显示文摘AIM: To understand the local pathophysiological altera- tions and gene ontology-based functional classification of colonic biopsies into inflammatory and neoplastic dis- eases. METHODS: Total RNA was extracted from frozen biop- sies and amplified by T7-method. Expression profile was evaluated by Atlas Glass 1K microarrays. After microar- ray quality control, applicable data were available from 10 adenomas, 6 colorectal adenocarcinomas (CRCs), and 6 inflammatory bowel diseases (IBDs). Multivariate statistical and cell functional analyses were performed. Real-time RT-PCR and immunohistochemistry were used for validation. RESULTS: Discriminant analysis of selected genes, could correctly reclassify all 22 samples using 4 parameters (heat shock transcription factor-1, bystin-like, calgranu- lin-A, TRAIL receptor 3). IBD samples were characterized by overregulated chemokine (C-X-C motif) ligand 13, replication protein A1, E74-like factor 2 and downregu- lated TNF receptor-associated factor 6, BCL2-interacting killer genes. In adenomas upregulation of TNF receptor- associated factor 6, replication protein A1, E74-like factor 2 and underexpression of BCL2-associated X protein, cal- granulin-A genes were found. CRC cases had significantly increased epidermal growth factor receptor, topoisomer- ase-1, v-jun, TNF receptor-associated factor 6 and TRAIL receptor 3, and decreased RAD51 and RAD52 DNA repair gene, protein phosphatase-2A and BCL2-interacting killer mRNA levels. Epidermal growth factor receptor RT-PCR and immunohistochemistry, topoisomerase-1 RT-PCRconfirmed the chip results. CONCLUSION: Different histological alterations can be reclassified by functional, multivariate analysis using cDNA microarrays. Further studies with expanded sample number are needed for subclassification of pathological alterations. | Orsolya Galamb Ferenc Sipos Elek Dinya Sandor Spisak Zsolt Tulassay Bela Molnar | 2006 | World Journal of Gastroenterology2006，12，43： | 2 |
| 10 | 体育运动与活性氧对大脑的复杂作用显示文摘活性氧(ROS)在有氧代谢中以中度水平持续产生,有利于产生氧化还原信号,但数量较大时却能引起氧化损伤和神经退行性病变。由于大脑对ROS敏感度提高,在不同类型神经细胞中保持正常氧化还原状态尤为重要。过去10年的研究充分说明:有规律的运动对大脑功能产生有益影响,并对中风、老年痴呆和帕金森症的预防和治疗起重要作用。然而,研究运动的具体影响似乎又非常复杂,包括通过神经营养因子的神经发生、毛细血管化增加、氧化损伤减少,以及通过蛋白酶和脑啡肽酶的蛋白降解增加。来自我们及其他实验室的数据表明,运动诱导的ROS水平调节对蛋白含量以及脑源性神经营养因子(BDNF)、酪氨酸激酶B(TrkB)、cAMP反应元件结合蛋白(CREB)的表达有重要作用,有利于完善脑功能、增加神经生成。因此,运动诱导的氧化还原状态调节是一种重要方式,运动能通过这一方式造福于大脑功能、增强对氧化应激的抵抗力,协助从氧化应激中恢复、减弱年龄相关的认知能力下降。 | Zsolt Radak Orsolya Marton Eniko Nagy Erika Koltai Sataro Goto | 2013 | Journal of Sport and Health Science2013，2，2： | 2 |
