| 1 | Multiplex RT-PCR-based detections of CEA, CK20 and EGFR in colorectal cancer patients显示文摘AIM: To develop a multiplex reverse transcription polymerase chain reaction (RT-PCR) method detecting cir-culating tumor cells in the peripheral blood of colorectal cancer (CRC) patients. METHODS: Peripheral blood samples were collected from 88 CRC patients and 40 healthy individuals from the blood donors' clinic and subsequently analyzed by multiplex RT-RCR for the expression of carcinoembryonic antigen (CEA), cytokeratin 20 (CK20) and epidermal growth factor receptor (EGFR) mRNA. The analysis involved determining the detection rates of CEA, CK20 and EGFR transcripts vs disease stage and overall survival. Median follow-up period was 19 mo (range 8-28 mo). RESULTS: Rates of CEA, CK20 and EGFR detection in CRC patients were 95.5%, 78.4% and 19.3%, respectively. CEA transcripts were detected in 3 healthy volunteer samples (7.5%), whereas all control samples were tested negative for CK20 and EGFR transcripts. The increasing number of positive detections for CEA, CK20 and EGFR transcripts in each blood sample was positively correlated with Astler-Coller disease stage (P< 0.001) and preoperative serum levels of CEA (P=0.029) in CRC patients. Data analysis using Kaplan-Meier estimator documented signif icant differences in the overall survival of the different CRC patient groups as formed according to the increasing number of positivity for CEA, CK20 and EGFR transcripts. CONCLUSION: These data suggest that multiplex RTPCR assay can provide useful information concerning disease stage and overall survival of CRC patients. | Aikaterini Tsouma Chrysanthi Aggeli Panagiotis Lembessis George N Zografos Dimitris P Korkolis Dimitrios Pectasides Maria Skondra Nikolaos Pissimissis Anastasia Tzonou Michael Koutsilieris | 2010 | World Journal of Gastroenterology2010，16，47： | 19 |
| 2 | Mitochondrial dysfunction and mitochondrial DNA mutations in atherosclerotic complications in diabetes显示文摘Mitochondrial DNA(mtDNA) is particularly prone to oxidation due to the lack of histones and a deficient mismatch repair system.This explains an increased mutation rate of mtDNA that results in heteroplasmy,e.g.,the coexistence of the mutant and wild-type mtDNA molecules within the same mitochondrion.In diabetes mellitus,glycotoxicity,advanced oxidative stress,collagen cross-linking,and accumulation of lipid peroxides in foam macrophage cells and arterial wall cells may significantly decrease the mutation threshold required for mitochondrial dysfunction,which in turn further contributes to the oxidative damage of the diabetic vascular wall,endothelial dysfunc-tion,and atherosclerosis. | Dimitry A Chistiakov Igor A Sobenin Yuri V Bobryshev Alexander N Orekhov | 2012 | World Journal of Cardiology2012，4，5： | 17 |
| 3 | Brain stem cells as the cell of origin in glioma显示文摘Glioma incidence rates in the United States are near 20000 new cases per year, with a median survival time of 14.6 mo for high-grade gliomas due to limited therapeutic options. The origins of these tumors and their many subtypes remain a matter of investigation. Evidence from mouse models of glioma and human clinical data have provided clues about the cell types and initiating oncogenic mutations that drive gliomagenesis, a topic we review here. There has been mixed evidence as to whether or not the cells of origin are neural stem cells, progenitor cells or differentiated progeny. Many of the existing murine models target cell populations defined by lineage-specific promoters or employ lineagetracing methods to track the potential cells of origin. Our ability to target specific cell populations will likely increase concurrently with the knowledge gleaned from an understanding of neurogenesis in the adult brain. The cell of origin is one variable in tumorigenesis, as oncogenes or tumor suppressor genes may differentially transform the neuroglial cell types. Knowledge of key driver mutations and susceptible cell types will allow us to understand cancer biology from a developmental standpoint and enable early interventional strategies and biomarker discovery. | Aram S Modrek N Sumru Bayin Dimitris G Placantonakis | 2014 | World Journal of Stem Cells2014，6，1： | 12 |
| 4 | 一种miRNA标记在胶质瘤侵袭性表型的确定与预后评估中的价值(英文)显示文摘Gliomas represent a disparate group of tumours for which there are to date no cure. Thus,there is a recognized need for new diagnostic and therapeutic approaches based on increased understanding of their molecular nature. We performed the comparison of the microRNA( miRNA) profile of 8 WHO grade II gliomas and 24 higher grade tumours( 2 WHO grade III and 22 glioblastomas) by using the Affymetrix Gene Chip miRNA Array v. 1. 0. A relative quantification method( RT-q PCR) with standard curve was used to confirm the 22 miRNA signature resulted by array analysis. The prognostic performances of the confirmed miRNAs were estimated on the Tumor Cancer Genome Atlas( TCGA) datasets. We identified 22 miRNAs distinguishing grade II gliomas from higher grade tumours.RT-q PCR confirmed the differential expression in the two patients' groups for 13 out of the 22 miRNAs. The analysis of the Glioblastoma Multiforme( GBM) and Lower Grade Glioma( LGG) datasets from TCGA demonstrated the association with prognosis for 6 of those miRNAs. Moreover,in the GBM dataset miR-21 and miR-210 were predictors of worse prognosis in both univariable and multivariable Cox regression analyses( HR 1. 19,P = 0. 04,and HR 1. 18,P = 0. 029 respectively). Our results support a direct contribution of miRNAs to glioma cancerogenesis and suggest that miR-21 and miR-210 may play a role in the aggressive clinical behaviour of glioblastomas. | Barbano R Palumbo O Pasculli B Galasso M Volinia S D'Angelo V Icolaro N Coco M Dimitri L Graziano P Copetti M Valori VM Maiello E Carella M Fazio VM Parrella P | 2014 | 中华神经外科疾病研究杂志2014，13，5： | 6 |
| 5 | Association of the level of heteroplasmy of the 15059G>A mutation in the MT-CYB mitochondrial gene with essential hypertension显示文摘AIM: To examine whether the heteroplasmy level for 15059G>A mutation in the mitochondrial genome might be associated with essential hypertension. METHODS: This cross-sectional study involved 196 unrelated participants randomly selected from general population (90 males and 106 females) who underwent a regular medical check-up at the Institute for Ath-erosclerosis Research (Moscow, Russia). One hundred and twenty of them (61%) had essential hypertension, and 76 (39%) were apparently healthy normotensive persons. The level of heteroplasmy for 15059G>A mutation occurring in the coding region of cytochrome b gene (MT-CYB) of mtDNA isolated from the blood leukocytes, was quantified using DNA pyrosequencing method. RESULTS: The 15059G>A heteroplasmy level ranged between 4% and 83%, with a median level of 31%. Between the upper and lower quartiles of 15059G>A heteroplasmy distribution, significant differences were observed for patients' age, systolic blood pressure, and triglyceride levels. 15059G>A heteroplasmy correlated both with age (r = 0.331, P < 0.001) and the presence of hypertension (r = 0.228, P = 0.002). Regression analysis revealed that the age explains 12% variability of 15059G>A heteroplasmy, and hypertension independently explains more 5% variability. The 15059G>A heteroplasmy exceeding 31% was found to be significantly associated with a higher risk of essential hypertension (odds ratio 2.76; P (Fisher) 0.019]. The study participants with high 15059G>A heteroplasmy level were found to have significantly higher age (P < 0.001) and the prevalence of essential hypertension (P = 0.033), as compared to those with low 15059G>A heteroplasmy level. These observations suggested a positive correlation between the level of 15059G>A heteroplasmy and essential hypertension. CONCLUSION: This study provides the evidence of association of mtDNA 15059G>A mutation heteroplasmy with essential hypertension. | Igor A Sobenin Dimitry A Chistiakov Margarita A Sazonova Maria M Ivanova Yuri V Bobryshev Alexander N Orekhov Anton Y Postnov | 2013 | World Journal of Cardiology2013，5，5： | 3 |
| 6 | Solitary fibrous tumor of the liver expressing CD34 and vimentin:A case report显示文摘A case of a successfully treated solitary fibrous tumor (SFT) of the liver is reported.An 82-year-old female presented with left upper abdominal discomfort,a firm mass on palpation,and imaging studies revealed a large tumor,15 cm in diameter,arising from the left lobe of the liver.A formal left hepatectomy was performed.Microscopic evaluation showed spindle and fibroblast-like cells within the collagenous stroma.Immunohistochemistry disclosed diffuse CD34 and positive vimentin,supporting the diagnosis of a benign SFT.The patient remained well 21 months after surgery.SFT of the liver is a very rare neoplasm of mesenchymal origin.In most cases it is a benign lesion,although some may have malignant histological features and recur locally or metastasize.With less than 30 reported cases in the literature,little can be said regarding its natural history or the benefits of adjuvant radiochemotherapy.Complete surgical resection remains the cornerstone of its treatment. | Dimitris P Korkolis Katerina Apostolaki Chrysanthi Aggeli George Plataniotis Emmanuel Gontikakis Dimitra Volanaki Maria Sebastiadou Dimitris Dimitroulopoulos Dimitris Xinopoulos George N Zografos Perikles P Vassilopoulos | 2008 | World Journal of Gastroenterology2008，14，40： | 3 |
