| 1 | A nuclear import inhibitory peptide ameliorates the severity of cholecystokinin-induced acute pancreatitis显示文摘AIM: To assess the effect of our novel cell-permeable nuclear factor-kappaB (NF-κB) inhibitor peptide PN50 in an experimental model of acute pancreatitis. PN50 was produced by conjugating the cell-penetrating penetratin peptide with the nuclear localization signal of the NF-κB p50 subunit.METHODS: Pancreatitis was induced in male Wistar rats by administering 2×100 μg/kg body weight of cholecystokininoctapeptide (CCK) intraperitoneally (IP) at an interval of 1 h. PN50-treated animals received 1 mg/kg of PN50 IP 30 min before or after the CCK injections. The animals were sacrificed 4 h after the first injection of CCK.RESULTS: All the examined laboratory (the pancreatic weight/body weight ratio, serum amylase activity,pancreatic levels of TNF-α and IL-6, degree of lipid peroxidation, reduced glutathione levels, NF-κB binding activity, pancreatic and lung myeloperoxidase activity) and morphological parameters of the disease were improved before and after treatment with the PN50 peptide.According to the histological findings, PN50 protected the animals against acute pancreatitis by favoring the induction of apoptotic, as opposed to necrotic acinar cell death associated with severe acute pancreatitis.CONCLUSION: Our study implies that reversible inhibitors of stress-responsive transcription factors like NF-κB might be clinically useful for the suppression of the severity of acute pancreatitis. | Tamás Letoha Csaba Somlai Tamáas Takács Annamária Szabolcs Katalin Jármay Zoltán Rakonczay Jr Péter Hegyi Ilona Varga József Kaszaki István Krizbai Imre Boros Ern(?)

| 2 | Therapeutic proteasome inhibition in experimental acute pancreatitis显示文摘AIM: To establish the therapeutic potential of proteasome inhibition, we examined the therapeutic effects of MG132 (Z-Leu-Leu-Leu-aldehyde) in an experimental model of acute pancreatitis.METHODS: Pancreatitis was induced in rats by two hourly intraperitoneal (ip) injections of cholecystokinin octapeptide (CCK; 2 x 100 μg/kg) and the proteasome inhibitor MG132 (10 mg/kg ip) was administered 30 min after the second CCK injection. Animals were sacrificed 4 h after the first injection of CCK.RESULTS: Administering the proteasome inhibitor MG132 (at a dose of 10 mg/kg, ip) 90 min after the onset of pancreatic inflammation induced the expression of cell-protective 72 kDa heat shock protein (HSP72) and decreased DNA-binding of nuclear factor-kB (NF-kB). Furthermore MG132 treatment resulted in milder inflammatory response and cellular damage, as revealed by improved laboratory and histological parameters of pancreatitis and associated oxidative stress.CONCLUSION: Our findings suggest that proteasome inhibition might be beneficial not only for the prevention, but also for the therapy of acute pancreatitis. | Tamás Letoha Liliána Z Fehér László Pecze Csaba Somlai Ilona Varga József Kaszaki Gábor Tóth Csaba Vizler László Tiszlavicz Tamás Takács | 2007 | World Journal of Gastroenterology2007,13,33: | 5 |
| 3 | Clinical significance of granuloma in Crohn's disease显示文摘AIM: Granuloma is considered the hallmark of microscopic diagnosis in Crohn's disease (CD), but granulomas can be detected in only 21-60% of CD patients. The aim of this studywas to evaluate the frequency of granulomas by multiple endoscopic biopsies in patients with CD and to examine whether group of patients with or without granuloma exhibit a different clinical course.METHODS: Fifty-six patients with newly diagnosed Cdwere included in the study. Jejunoscopy, enteroclysis and ileo-colonoscopy were performed in all patients. At least two biopsy specimens from each examined gastrointestinal segment were examined microscopically searching granuloma. The clinical course was followed in all patients, and extraintestinal manifestations as well as details of any immunosuppressive therapy and surgical intervention were noted.RESULTS: Granuloma was found in 44.6% of the cases (25 patients). Patients with granuloma had higher activity parameters at the time of the biopsies. Extraintestinal manifestations were observed and surgical interventions were performed more often in the granuloma group. The need of immunosuppressive therapy was significantly more frequent in the patients with granuloma. Granuloma formation is more often seen in younger patients, and mainly in the severe, active penetrating disease. CONCLUSION: The significantly higher frequency of surgical interventions and immunosuppressive therapy suggests that granuloma formation is associated with a more severe disease course during the first years of CD. | Tamás Molnár László Tiszlavicz Csaba Gyulai Ferenc Nagy János Lonovics | 2005 | World Journal of Gastroenterology2005,11,20: | 5 |
| 4 | Relevance of α-defensins(HNP1-3) and defensin β-1 in diabetes显示文摘AIM: To investigate the genetic background of human defensin expression in type 1 and 2 diabetes.METHODS: Associations between DEFA1/DEFA3 gene copy number polymorphism and diabetes as well as between the promoter polymorphisms of DEFB1 and diabetes were studied. The copy number variation of the DEFA1/DEFA3 genes was determined in 257 diabetic patients(117 patients with type 1 and 140 with type 2 diabetes). The control group consisted of 221 age- and gender-matched healthy blood donors. The cumulative copy numbers of the DEFA1/DEFA3 genes were detected by using quantitative PCR analysis. To evaluate the HNP 1-3(human neutrophil peptide 1-3 or α-defensin) levels in the circulation, plasma HNP 1-3 concentrations were measured by ELISA. The expression of DEFA1/A3 in peripheral leukocytes of the diabetic patients was measured by quantitative RT PCR analysis. Three SNPs of the human DEFB1(human defensin β-1) gene: DEFB1 G-20A(rs11362), DEFB1 C-44G(rs1800972) and DEFB1 G-52A(rs1799946) were genotyped by Custom TaqMan? Real Time PCR assay.RESULTS: Significant differences were observed in HNP1-3 levels between the healthy subjects and both groups of diabetic patients. The mean ± SE was 28.78 ± 4.2 ng/mL in type 1 diabetes, and 29.82 ± 5.36 ng/mL in type 2 diabetes, vs 11.94 ± 2.96 ng/mL in controls; P < 0.01 respectively. There was no significant difference between patients with type 1 and type 2 diabetes in the high plasma concentrations of HNP1-3. The highest concentrations of α-defensin were found in diabetic patients with nephropathy(49.4 ± 4.8 ng/mL), neuropathy(38.7 ± 4.8 ng/mL) or cardiovascular complications(45.6 ± 1.45 ng/L). There was no significant difference in the cumulative copy numbers of DEFA1/DEFA3 genes between controls and patients, or between patients with the two types of diabetes. Comparisons of HNP 1-3 plasma level and DEFA1/A3 copy number of the same patient did not reveal significant relationship between defensin-α levels and the gene copy numbers(r2 = 0.01). Similarly, no positive correlation was observed between the copy numbers and the mRNA expression levels of DEFA1/A3. Regarding the C-44G polymorphism of DEFB1, the GG 'protective' genotype was much less frequent(1%-2%) among both groups of patients than among controls(9%).CONCLUSION: Elevated HNP1-3 levels in diabetes are independent of DEFA1/DEFA3 copy numbers, but GG genotype of C-44G SNP in DEFB1 gene may result in decreased defensin β-1 production. | Balázs Csaba Németh Tamás Várkonyi Ferenc Somogyvári Csaba Lengyel Katalin Fehértemplomi Szabolcs Nyiraty Péter Kempler Yvette Mándi | 2014 | World Journal of Gastroenterology2014,20,27: | 4 |
| 5 | Is early limited surgery associated with a more benign disease course in Crohn's disease?显示文摘AIM:To analyze the difference in disease course and need for surgery in patients with Crohn’s disease(CD).METHODS:Data of 506 patients with incident CD were analyzed(age at diagnosis:31.5±13.8 years).Both hospital and outpatient records were collected prospectively with a complete clinical follow-up and comprehensively reviewed in the population-based Veszprem province database,which includes incident CD patients diagnosed between January 1,1977 and December 31,2008.Follow-up data were collected until December 31,2009.All patients included had at least 1year of follow-up available.Patients with indeterminate colitis at diagnosis were excluded from the analysis.RESULTS:Overall,73 patients(14.4%)required resective surgery within 1 year of diagnosis.Steroid exposure and need for biological therapy were lower in patients with early limited surgery(P<0.001 and P=0.09).In addition,surgery rates during follow-up in patients with and without early surgery differed significantly after matching on propensity scores(P<0.001,HR=0.23).The need for reoperation was also lower in patients with early limited resective surgery(P=0.038,HR=0.42)in a Kaplan-Meier and multivariate Cox regression(P=0.04)analysis.However,this advantage was not observed after matching on propensity scores(PLogrank=0.656,PBreslow=0.498).CONCLUSION:Long-term surgery rates and overall exposure to steroids and biological agents were lower in patients with early limited resective surgery,but reoperation rates did not differ. | Petra Anna Golovics Laszlo Lakatos Attila Nagy Tunde Pandur Istvan Szita Mihaly Balogh Csaba Molnar Erzsebet Komaromi Barbara Dorottya Lovasz Michael Mandel Gabor Veres Lajos S Kiss Zsuzsanna Vegh Peter Laszlo Lakatos | 2013 | World Journal of Gastroenterology2013,19,43: | 3 |
| 6 | Increased duodenal expression of mi R-146a and-155 in pediatric Crohn's disease显示文摘AIM: To evaluate the role of micro RNA(mi R)-146 a,-155 and-122 in the duodenal mucosa of pediatric patients with Crohn's disease(CD) and the effect of transforming growth factor-β(TGF-β) on these mi Rs in duodenal epithelial and fibroblast cells.METHODS: Formalin-fixed, paraffin-embedded biopsies derived from the macroscopically inflamed(CD inflamed: n = 10) and intact(CD intact: n = 10) duodenal mucosa of pediatric CD patients and control children(C: n = 10) were examined. Expression of mi R-146 a,-155 and-122 was determined by realtime polymerase-chain reaction(PCR). The expression of the above mi Rs was investigated in recombinant human TGF-β(1 nmol/L, 24 h) or vehicle treated small intestinal epithelial cells(CCL-241) and primary duodenal fibroblast cells derived from healthy children as well.RESULTS: Expression of mi R-146 a was significantly higher in the inflamed duodenal mucosa compared to the intact duodenal mucosa of children with CD(CD inflamed: 3.21 ± 0.50 vs CD intact: 0.62 ± 0.26, p ≤ 0.01) and to the control group(CD inflamed: 3.21 ± 0.50 vs C: 1.00 ± 0.33, p ≤ 0.05). The expression of mi R-155 was significantly increased in the inflamed region of the duodenum compared to the control group(CD inflamed: 4.87 ± 1.02 vs Control: 1.00 ± 0.40, p ≤ 0.001). The expression of mi R-122 was unchanged in the inflamed or intact mucosa of CD patients compared to controls. TGF-β treatment significantly decreased the expression of mi R-155 in small intestinal epithelial cells(TGF-β: 0.7 ± 0.083 vs Control: 1 ± 0.09, p ≤ 0.05) and also the expression of mi R-146a(TGF-β: 0.67 ± 0.04 vs Control: 1 ± 0.15, p ≤ 0.01) and mi R-155(TGF-β: 0.72 ± 0.09 vs Control: 1 ± 0.06, p ≤ 0.05) in primary duodenal fibroblasts compared to corresponding vehicle treated controls. TGF-β treatment did not influence the expression of mi R-122.CONCLUSION: The elevated expression of mi R-146 a and-155 in the inflamed duodenal mucosa of CD patients suggests the role of these mi Rs in the pathomechanism of inflammatory bowel disease. Antiinflammatory TGF-β plays an important role in the regulation of the expression of these mi Rs. | Dániel Szucs Nóra Judit Béres Réka Rokonay Kriszta Boros Katalin Borka Zoltán Kiss András Arató Attila J Szabó ádám Vannay Erna Sziksz Csaba Bereczki Gábor Veres | 2016 | World Journal of Gastroenterology2016,22,26: | 2 |
