| 1 | Fintech investments in European banks:a hybrid IT2 fuzzy multidimensional decision‑making approach显示文摘Financial technology(Fintech)makes a significant contribution to the financial system by reducing costs,providing higher quality services and increasing customer satisfaction.Hence,new studies play an essential role to improve Fintech investments.This study evaluates Fintech-based investments of European banking services with an application of an original methodology that considers interval type-2(IT2)fuzzy decision-making trial and evaluation laboratory and IT2 fuzzy TOPSIS models.Empirical findings are controlled for consistency by applying the VIKOR method.Moreover,we conduct a sensitivity analysis by considering six distinct cases.This study contributes to the existing literature by identifying the most important Fintech-based investment alternatives to improve the financial performance of European banks.Our empirical findings illustrate that results are coherent,reliable,and identify“competitive advantage”as the most important factor among Fintech-based determinants.Moreover,“payment and money transferring systems”are the most important Fintech-based investment alternatives.It is recommended that,among Fintech-based investments,European banks should mainly focus on payment and money transferring alternatives to attract the attention of customers and satisfy their expectations.This is also believed to have a positive impact on the ease of bank’receivable collection.Another important point is that Fintech-based investments in money transferring systems could help to decrease costs. | Gang Kou Ozlem Olgu Akdeniz Hasan Dincer Serhat Yuksel | 2021 | Financial Innovation2021,7,1: | 38 |
| 2 | Angiogenesis and liver fibrosis显示文摘Recent data indicate that hepatic angiogenesis, regardless of the etiology, takes place in chronic liver diseases(CLDs) that are characterized by inflammat ion and progre s s ive f ibros is. B e c aus e ant iangiogenic therapy has been found to be efficient in the prevention of fibrosis in experimental models of CLDs, it is suggested that blocking angiogenesis could be a promising therapeutic option in patients with advanced fibrosis. Consequently, efforts are being directed to revealing the mechanisms involved in angiogenesis during the progression of liver fibrosis. Literature evidences indicate that hepatic angiogenesis and fibrosis are closely related in both clinical andexperimental conditions. Hypoxia is a major inducer of angiogenesis together with inflammation and hepatic stellate cells. These profibrogenic cells stand at the intersection between inflammation, angiogenesis and fibrosis and play also a pivotal role in angiogenesis. This review mainly focuses to give a clear view on the relevant features that communicate angiogenesis with progression of fibrosis in CLDs towards the-end point of cirrhosis that may be translated into future therapies. The pathogenesis of hepatic angiogenesis associated with portal hypertension, viral hepatitis, non-alcoholic fatty liver disease and alcoholic liver disease are also discussed to emphasize the various mechanisms involved in angiogenesis during liver fibrogenesis. | Gulsum Ozlem Elpek | 2015 | World Journal of Hepatology2015,7,3: | 24 |
| 3 | Clinical characteristics of Caroli's syndrome显示文摘Caroli's syndrome is characterized by multiple segmental cystic or saccular dilatations of intrahepatic bile ducts associated with congenital hepatic fibrosis. The clinical features of this syndrome reflect both the characteristics of congenital hepatic fibrosis such as portal hypertension and that of Caroli's disease named as recurrent cholangitis and cholelithiasis. The diagnosis depends on both histology and imaging methods which can show the communication between the sacculi and the bile ducts. Treatment consists of symptomatic treatment of cholangitis attacks by antibiotics, some endoscopic, radiological and surgical drainage procedures and surgery. Liver transplantation seems the ultimate treatment for this disease. Prognosis is fairly good unless recurrent cholangitis and renal failure develops. | Ozlem Yonem Yusuf Bayraktar | 2007 | World Journal of Gastroenterology2007,13,13: | 22 |
| 4 | Maastricht Ⅱ treatment scheme and efficacy of different proton pump inhibitors in eradicating Helicobacter pylori显示文摘AIM: The Maastricht Ⅱ criteria suggest the use of amoxicillin and clarithromycin in addition to a proton pump inhibitor over 7-10 d as a first line therapy in the eradication of Helicobacter pylori (Hpylori). For each proton pump inhibitor, various rates of eradication have been reported. The present study was to compare the efficacy of different proton pump inhibitors like omeprazole, lansoprazole and pantoprazole in combination with amoxicillin and clarithromycin in the first line eradication of Hpylonand to investigate the success of H pylonrieradication in our district. METHODS: A total of 139 patients were included having a Helicobacter pylori (+) gastroduodenal disorders diagnosed by means of histology and urease test. Besides amoxicillin (1000 mg twice a day) and darithromycin (500 mg twice a day), they were randomized to take omeprazole (20 mg twice a day), or lansoprazole (30 mg twice a day), or pantoprozole (40 mg twice a day) for 14 d. Four weeks after the therapy, the eradication was assessed by means of histology and urease test. It was evaluated as eradicated if the Hpyloriwas found negative in both. The complaints (pain in epigastrium, nocturnal pain, pyrosis and bloating) were graded in accordance with the Licert scale. The compliance of the patients was recorded. RESULTS: The eradication was found to be 40.8% in the omeprazole group, 43.5% in the lansoprazole group and 47.4% in the pantoprazole group. Sixty-three out of 139 patients (45%) had eradication. No statistically significant difference was observed between the groups. Significant improvements were seen in terms of the impact on the symptom scores in each group. CONCLUSION: There was no difference between omeprazole, lansoprazole and pantoprazole in H pylori eradication, and the rate of eradication was as low as 45%. Symptoms were improved independent of the eradication in each treatment group. The low eradication rates suggest that the antibiotic resistance or the genetic differences of the microorganism might be in effect. Further studies are required to verify these suggestions. | EnginAltintas OrhanSezgin Oguz Ulu Ozlem Avdin Handan Camdeviren | 2004 | World Journal of Gastroenterology2004,10,11: | 23 |
| 5 | Clinical probability and risk analysis of patients with suspected pulmonary embolism显示文摘BACKGROUND: Pulmonary embolism(PE) is one of the most frequent diseases that could be missed in overcrowded emergency departments as in Turkey. Early and accurate diagnosis could decrease the mortality rate and this standard algorithm should be defi ned. This study is to fi nd the accurate, fast, non-invasive, cost-effective, easy-to-access diagnostic tests, clinical scoring systems and the patients who should be tested for clinical diagnosis of PE in emergency department.METHODS: One hundred and forty patients admitted to the emergency department with the fi nal diagnosis of PE regarding to anamnesis, physical examination and risk factors, were included in this prospective, cross-sectional study. The patients with a diagnosis of pulmonary embolism, acute coronary syndrome or infection and chronic obstructive pulmonary disease(COPD) were excluded from the study. The demographics, risk factors, radiological fi ndings, vital signs, symptoms, physicallaboratory fi ndings, diagnostic tests and clinical scoring systems of patients(Wells and Geneva) were noted. The diagnostic criteria for pulmonary emboli were: fi lling defect in the pulmonary artery lumen on spiral computed tomographic angiography and perfusion defect on perfusion scintigraphy.RESULTS: Totally, 90(64%) of the patients had PE. Age, hypotension, having deep vein thrombosis were the risk factors, and oxygen saturation, shock index, BNP, troponin and fi brinogen levels as for the biochemical parameters were signifi cantly different between the PE(+) and PE(–) groups(P<0.05).The Wells scoring system was more successful than the other scoring systems.CONCLUSION: Biochemical parameters, clinical findings, and scoring systems, when used altogether, can contribute to the diagnosis of PE. | Gulden Ozeren Yetgin Sule Akkose Aydin Ozlem Koksal Fatma Ozdemir Dilek Kostak Mert Gokhan Torun | 2014 | World Journal of Emergency Medicine2014,5,4: | 20 |
| 6 | Clinical characteristics of Caroli’s disease显示文摘Caroli's disease is a rare congenital condition chara- cterized by non-obstructive saccular or fusiform dilatation of larger intrahepatic bile ducts. Cholangitis, liver cirrhosis, and cholangiocarcinoma are its potential complications. The diagnosis of Caroli's disease depends on demonstrating that the cystic lesions are in continuity with the biliary tree which can be showed by ultrasonography, computerized tomography, endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography or magnetic resonance cholangiopancreatography. Treatment of Caroli's disease relies on the location of the biliary abnormalities. While localized forms confined to one lobe can be treated with surgery, liver transplantation is the only effective modality for diffuse forms. Although a rare disorder; Caroli's disease should always be considered in the differential diagnosis of chronic cholestasis of unknown cause. | Ozlem Yonem Yusuf Bayraktar | 2007 | World Journal of Gastroenterology2007,13,13: | 18 |
| 7 | Increased levels of homocysteine in patients with ulcerative colitis显示文摘AIM: To investigate serum levels of homocysteine (Hcys) and the risk that altered levels carry for thrombosis development in ulcerative colitis (UC) patients. METHODS: 55 UC patients and 45 healthy adults were included. Hcys, vitamin B12 and folic acid levels were measured in both groups. Clinical history and thrombo- embolic events were investigated. RESULTS: The average Hcys level in the UC patients was 13.3 ± 1.93 μmmol/L (range 4.60-87) and was higher than the average Hcys level of the control group which was 11.2 ± 3.58 μmmol/L (range 4.00-20.8) (P < 0.001). Vitamin B12 and folic acid average values were also lower in the UC group (P < 0.001). Whenmultivariate regression analysis was performed, it was seen that folic acid deficiency was the only risk factor for hyperhomocysteinemia. Frequencies of thromboembolic complications were not statistically significantly different in UC and control groups. When those with and without a thrombosis history in the UC group were compared according to Hcys levels, it was seen that there were no statistically significant differences. A negative linear relationship was found between folic acid levels and Hcys. CONCLUSION: We could not find any correlations between Hcys levels and history of prior thromboembolic events. | Sabiye Akbulut Emin Altiparmak Firdevs Topal Ersan Ozaslan Metin Kucukazman Ozlem Yonem | 2010 | World Journal of Gastroenterology2010,16,19: | 13 |
| 8 | Synergistic effect of multiple predisposing risk factors on the development of bezoars显示文摘AIM:To describe the clinical characteristics of patients with gastric or intestinal bezoars recently treated in our hospital.METHODS:In this study,a retrospective chart review of consecutive patients with gastrointestinal bezoars,who were treated at the Samsun Education and Research Hospital between January 2006 and March 2011,was conducted.Data on demographic characteristics,clinical presentation,history of risk factors,diagnostic procedures,localization of bezoars,treatment interventions,and postoperative morbidity and mortality rates were collected and evaluated.RESULTS:Forty-two patients [26 (61.9%) males and 16 (31.1%) females] with a mean±SD (range) age of 55.8±10.5 (37-74) years were enrolled in this study.Thirty-six patients (85.7%) had one or more predisposing risk factors for gastrointestinal bezoars.The most common predisposing risk factor was a history of previous gastric surgery which was identified in 18 patients (42.8%).Twenty three patients (54.8%) had multiple predisposing risk factors.Phytobezoars were identified in all patients except one who had a trichobezoar in the stomach.Non-operative endoscopic fragmentation was performed either initially or after unsuccessful medical treatment in 14 patients with gastric bezoars and was completely successful in 10 patients (71.5%).Surgery was the most frequent treatment method in our study,which was required in 28 patients (66.7%).Intestinal obstruction secondary to bezoars was the most common complication (n=18,42.8%) in our study.CONCLUSION:The presence of multiple predisposing factors may create a synergistic effect in the development of bezoars. | Metin Kement Nuraydin Ozlem Elif Colak Sadik Kesmer Cem Gezen Selahattin Vural | 2012 | World Journal of Gastroenterology2012,18,9: | 11 |
| 9 | Biological subtypes of breast cancer: Prognostic and therapeutic implications显示文摘Breast cancer is a heterogeneous complex of diseases, a spectrum of many subtypes with distinct biological features that lead to differences in response patterns to various treatment modalities and clinical outcomes. Traditional classification systems regarding biological characteristics may have limitations for patient-tailored treatment strategies. Tumors with similar clinical and pathological presentations may have different behaviors. Analyses of breast cancer with new molecular techniques now hold promise for the development of more accurate tests for the prediction of recurrence. Gene signatures have been developed as predictors of response to therapy and protein gene products that have direct roles in driving the biology and clinical behavior of cancer cells are potential targets for the development of novel therapeutics. The present review summarizes current knowledge in breast cancer molecular biology, focusing on novel prognostic and predictive factors. | Ozlem Yersa L Sabri Barutca | 2014 | World Journal of Clinical Oncology2014,5,3: | 10 |
| 10 | Listening to Turkish classical music decreases patients’anxiety,pain,dissatisfaction and the dose of sedative and analgesic drugs during colonoscopy:A prospective randomized controlled trial显示文摘AIM: To determine whether listening to music decreases the requirement for dosages of sedative drugs, patients’ anxiety, pain and dissatisfaction feelings during colonoscopy and makes the procedure more comfortable and acceptable. METHODS: Patients undergoing elective colonoscopy between October 2005 and February 2006 were randomized into either listening to music (Group 1, n = 30) or not listening to music (Group 2, n = 30). Anxiolytic and analgesic drugs (intravenous midazolam and meperidine) were given according to the patients’ demand. Administered medications were monitored. We determined their levels of anxiety using the State-Trait Anxiety Inventory Test form. Patients’ satisfaction, pain, and willingness to undergo a repeated procedure were self-assessed using a visual analog scale.RESULTS: The mean dose of sedative and analgesic drugs used in group 1 (midazolam: 2.1 ± 1.4, meperidine: 18.1 ± 11.7) was smaller than group 2 (midazolam: 2.4 ± 1.0, meperidine: 20.6 ± 11.5), but without a significant difference (P > 0.05). The mean anxiety level in group 1 was lower than group 2 (36.7 ± 2.2 vs 251.0 ± 1.9, P < 0.001). The mean satisfaction score was higher in group 1 compared to group 2 (87.8 ± 3.1 vs 58.1 ± 3.4, P < 0.001). The mean pain score in group 1 was lower than group 2 (74.1 ± 4.7 vs 39.0 ± 3.9, P < 0.001).CONCLUSION: Listening to music during colonoscopy helps reduce the dose of sedative medications, as well as patients’ anxiety, pain, dissatisfaction during the procedure. Therefore, we believe that listening to music can play an adjunctive role to sedation in colonoscopy. It is a simple, inexpensive way to improve patients’ comfort during the procedure. | Nimet Ovayolu Ozlem Ucan Seda Pehlivan Yavuz Pehlivan Hakan Buyukhatipoglu M Cemil Savas Murat T Gulsen | 2006 | World Journal of Gastroenterology2006,12,46: | 10 |

| 12 | Is portal vein cavernous transformation a component of congenital hepatic fibrosis?显示文摘Congenital hepatic fibrosis (CHF) is an autosomal recessive disorder that belongs to the family of fibropolycystic liver diseases. This family includes a spectrum of disorders which are usually found in combination with each other and are usually inherited. Clinically fibropolycystic diseases have three effects being present in different proportions, those of a space occupying lesion, of portal hypertension and of cholangitis. In most patients, the first manifestations of CHF are signs and symptoms related to portal hypertension such as splenomegaly and varices. Portal hypertension in these patients has been attributed to the hypoplasia or compression of the portal vein radicles in the fibrous bands. Cavernous transformation of the portal vein (CTPV) is a relatively rare condition resulting from extrahepatic portal vein obstruction with recanalization or collateral vein formation to bypass the obstruction. It has been found that patients with CHF having an accompanying CTPV have relatively large splenomegaly and suffers more frequent episodes of bleeding from esophageal varices.We believe that CTPV is a congenital component of CHF and also one of the important causative factors of portal hypertension in these patients. | Ozlem Yonem Yusuf Bayraktar | 2007 | World Journal of Gastroenterology2007,13,13: | 9 |
| 13 | Gastric polypoid lesions:Analysis of 150 endoscopic polypectomy specimens from 91 patients显示文摘AIM: To analyze gastric polypoid lesions in our patientpopulation with respect to histopathologic features and demographic, clinical, and endoscopic characteristics of patients.METHODS: Clinical records and histopathologic reports of patients with gastric polypoid lesions were analyzed retrospectively. All lesions had been totally removed by either endoscopic polypectomy or hot biopsy forceps. The histopathologic slides were re-evaluated by the same histopathologist.RESULTS: One-hundred and fifty gastric polypoid lesions were identified in 91 patients. There were 53 (58%) women and 38 (42%) men with a median age of 53 (range, 31 to 82) years. The most frequent presenting symptom was dyspepsia that was observed in 35 (38.5%) patients.Symptoms were mostly related to various associated gastric abnormalities such as chronic gastritis or H pylori infection rather than polypoid lesion itself. Polypoid lesions were commonly located in the antrum followed by cardia. Out of 150 lesions, 80 (53%) had the largest dimensions less than or equal to 5 mm and only 7 were pedunculated. The frequencies of hyperplastic polyps, foveolar hyperplasia, and fundic gland polyps were 46%, 18%, and 14% respectively.We also detected gastritis varioliformis in 12 specimens,lymphoid follicles in 9, 4 adenomatous polyps in 4, polypoid lesions with edematous mucosa in 4, inflammatory polyps in 3, and carcinoid tumor in 1. Adenomatous changes were observed within two hyperplastic polyps and low grade dysplasia in one adenoma. Histopathologic evaluation of the surrounding gastric mucosa demonstrated chronic gastritis in 72 (79%) patients and H pylori infection in 45 (49%).CONCLUSION: Hyperplastic polyps are the most frequently encountered subtype of gastric polypoid lesions. They are usually associated with chronic gastritis or H pylori gastritis. Contrary to the previous belief, they may harbour adenomatous changes or dysplastic foci.Therefore, endoscopic polypectomy seems as a safe and fast procedure for both diagnosis and treatment of gastric polypoid lesions at the same session. In addition,edematous mucosa may appear misleadingly as a polypoid lesion in some instances and it can be ruled out only by histopathologic examination. | Rasim Gencosmanoglu Ebru Sen-Oran Ozlem Kurtkaya-Yapicier Erol Avsar Aydin Sav Nurdan Tozun | 2003 | World Journal of Gastroenterology2003,9,10: | 8 |
| 14 | Ovarian stem cells:From basic to clinical applications显示文摘The field of reproductive biology has undergone significant developments in the last decade. The notion that there is a fixed reserve pool of oocytes before birth was established by Zuckerman in 1951. However, in 2004, an article published in nature challenged this central dogma of mammalian reproductive biology. Tilly's group reported the existence of ovarian germline stem cells(GSCs) in postnatal ovaries of mice and suggested that the bone marrow could be an extragonadal source of ovarian GSCs. These findings were strongly criticized; however, several independent groups have sincesuccessfully isolated and characterized ovarian GSCs in postnatal mice. The ovarian GSCs are located in the ovarian surface epithelium and express markers of undifferentiated GSCs. When transplanted into mouse ovaries, mouse ovarian GSCs could differentiate and produce embryos and offspring. Similarly, in a recent study, ovarian GSCs were found to be present in the ovaries of women of reproductive age. Conversely, there is increasing evidence that stem cells responsible for maintaining a healthy state in normal tissue may be a source of some cancers, including ovarian cancer. Cancer stem cells(CSCs) have been found in many tissues, including ovaries. Some researchers have suggested that ovarian cancer may be a result of the transformation and dysfunction of ovarian GSCs with self-renewal properties. Drug resistant and metastasisgenerating CSCs are responsible for many important problems affecting ovarian cancer patients. Therefore, the identification of CSCs will provide opportunities for the development of new therapeutic strategies for treatments for infertility and ovarian cancer. In this article, we summarize the current understanding of ovarian GSCs in adult mammals, and we also discuss whether there is a relationship between GSCs and CSCs. | Ozlem Bingol Ozakpinar Anne-Marie Maurer Derya Ozsavci | 2015 | World Journal of Stem Cells2015,7,4: | 8 |
| 15 | Importance of antimicrobial susceptibility testing for the management of eradication in Helicobacter pylori infection显示文摘The management of Helicobacter pylori(H. pylori) infection treatment differs from the common treatment protocol for other infectious diseases. Because culture-or molecular-guided approaches face several practical issues, such as the invasive procedures required to obtain gastric biopsy specimens and the lack of availability of routine laboratory testing in some places, H. pylori treatment includes the administration of two or three empirically selected antibiotics combined with a proton pump inhibitor rather than evidence-based eradication treatment. The efficacy of empirical therapy is decreasing, mostly due to increasing multiple resistance. Multiresistance to levofloxacin, clarithromycin, and metronidazole, which are commonly used in empirical treatments, appears to have increased in many countries. Mutations play a primary role in the antimicrobial resistance of H. pylori, but many different mechanisms can be involved in the development of antibiotic resistance. Determining and understanding these possible mechanisms might allow the development of new methods for the detection of H. pylori and the determination of antimicrobial resistance. A treatment based on the detection of antimicrobial resistance is usually more effective than empirical treatment. Nevertheless, such an approach before treatment is still not recommended in the Maastricht guidelines due to the difficulty associated with the routine application of available cultureor molecular-based susceptibility tests, which are usually administered in cases of treatment failure. The management of first and rescue treatments requires further research due to the steadily increase in antimicrobial resistance. | Nazli Arslan ozlem Yilmaz Ebru Demiray-Gürbüz | 2017 | World Journal of Gastroenterology2017,23,16: | 7 |
| 16 | Interobserver variation in histopathological assessment of Helicobacter pylori gastritis显示文摘AIM: Because the presence or absence of H pyloriinfection has important implications for therapeutic decisions based on histological assessment, the reproducibility of Sydneysystem is important. The study was designed to test the reproducibility of features of Helicobacter pylori gastritis, using the updated Sydney classification. METHODS: Gastric biopsies of 40 randomly selected cases of H pylori gastritis were scored semiquantitatively by three pathologists. Variables analysed included chronic inflammation,inflammatory activity, atrophy, intestinal metaplasia, H pylori,surface epithelial damage. k values below 0.5 represented poor, those between 0.5 and 0.75 good and values over 0.75 excellent interobserver agreement. RESULTS: The best interobserver agreement (k=0.62) was present for intestinal metaplasia. The agreement was the poorest for evaluating atrophy (k=0.31). CONCLUSION: Although the results of this study were in accordance with some previous studies, an excellent agreement could not be reached for any features of H pylori gastritis. This low degree of concordance is assumed to be due to the personal evaluation differences in grading the features, the lack of standardized diagnostic criteria, and the ignorance to reach a consensus about the methods to be used in grading the features of H pylori gastritis before initiating the study. | Ozlem Aydin Reyhan Egilmez Tuba Karabacak Arzu Kanik | 2003 | World Journal of Gastroenterology2003,9,10: | 6 |
| 17 | 吸烟,血清抗氧化维生素水平和老年性黄斑变性之间的关系(英文)显示文摘目的:研究老年性黄斑变性(AMD)等级、血清抗氧化维生素水平(维生素A、C和E)和吸烟的关系。方法:对84例患者行黄斑彩色眼底成像,根据AMD损伤率和损伤程度将其分为五组(等级I^V)。应用高效液相色谱法(HPLC)测量血清抗氧化维生素水平。根据吸烟状况分不吸烟者、已戒烟者和吸烟者三组,并统计吸烟者每年的吸烟总量。结果:对照组中,维生素A、E、C水平分别为0.874±0.326mg/L,10.739±4.874mg/L和1.737±0.447mg/L,AMD组中分别为0.880±0.305mg/L,9.487±6.060mg/L和1.870±2.191mg/L,无显著差异(P>0.05)。AMD不同等级分组间维生素A(P=0.881)和E(P=0.293)水平差异无统计学意义,维生素C水平(P=0.044)随AMD程度的加深而增加。根据吸烟状况,AMD组与对照组之间无显著差异。根据每年的吸烟总量,两组之间有显著差异(P=0.02)。AMD越严重,年吸烟总量越高(P=0.007)。结论:研究结果显示AMD与维生素A、E血清水平无关,但和维生素C的血清水平相关,并与吸烟量有关。 | Sezen Akkaya Cakir Ozlem Sahin Haluk Kazokoglu Feyza Tekeli Goncagul Haklar Yelda Ozkurt | 2014 | 国际眼科杂志2014,14,5: | 5 |
| 18 | Expression of Notch pathway components (Numb, Itch, and Siah-1) in colorectal tumors: A clinicopathological study显示文摘BACKGROUND The role of the Notch pathway in carcinogenesis and tumor progression has been demonstrated in many organs,including the colon.Accordingly,studies aimed at developing therapies targeting this pathway in various cancers require the identification of several factors that may play a role in regulating Notch-1 expression.Although Numb,Itch,and seven in absentia homolog-1(Siah-1)have been shown to contribute to the regulation of Notch signaling,their role in colorectal carcinogenesis and tumor progression has not been fully elucidated to date.AIM To evaluate Numb,Itch,and Siah-1 expression in colorectal tumors to clarify their relationship with Notch-1 expression and their role in carcinogenesis and tumor behavior.METHODS Expression of Notch-1,Numb,Itch,and Siah-1 was investigated in 50 colorectal carcinomas,30 adenomas,and 20 healthy colonic tissues by immunohistochemistry and quantitative real-time polymerase chain reaction(PCR)analyses.RESULTS In contrast to Notch-1,which is expressed at higher levels in tumor tissues and adenomas,expression of Numb,Itch,and Siah-1 was stronger and more frequent in normal mucosa(P<0.01).There was a positive correlation between Notch-1 expression and high histological grade,the presence of lymph node metastasis,and advanced-stage tumors,whereas expression of Numb,Itch,and Siah-1 was absent or reduced in tumors with these clinicopathological parameters(P<0.05).In survival analysis,expression of Notch was related to poor prognosis but that of Numb,Itch,and Siah-1 correlated with improved survival(P<0.05).Multivariate analysis revealed Notch-1 expression and loss of Numb expression to be independent prognostic parameters together with lymph node metastasis(P<0.05).CONCLUSION Our findings support the role of Notch-1 in colorectal carcinoma and indicate that loss of Numb,Itch,and Siah-1 expression is associated with carcinogenesis.Our data also suggest that these three proteins might be involved in the Notch-1 pathway during colorectal carcinoma(CRC)progression and might play an essential role in approaches targeting Notch as novel molecular therapies for CRC. | Sinem Cil Gonulcu Betul Unal Ibrahim Cumhur Bassorgun Mualla Ozcan Hasan Senol Coskun Gulsum Ozlem Elpek | 2020 | World Journal of Gastroenterology2020,26,26: | 5 |
