Ulcerative colitis (UC) is a chronic inflammatory disorder primarily affecting the colon mucosa. Its etiology and pathogenesis remain unclear. We used 2-DE and MS to identify differentially expressed proteins among the UC active, UC inactive, nonspecific colitis, and normal colon mucosa. Thirteen down-regulated and six up-regulated proteins were identified.(More)
To identify putative tumor suppressor genes in hepatocarcinogenesis, we combined the representational difference analysis and reverse northern blot identifying downregulated genes in human hepatoma tissues. One of them was Dkk-3/REIC. Dkk-3/REIC was downregulated in 11 out of the 20 human hepatoma tissues as compared to their counterparts of noncancerous(More)
Blood is an ideal source for biomarker discovery. However, little has been done to address the effects of sampling, handling and storage procedures on serum/plasma proteomes. We used magnetic bead-based MALDI-TOF MS to systematically evaluate the influence of each procedure on low-molecular-weight serum/plasma proteome profiling on the basis of the whole(More)
BACKGROUND AND AIM Gallbladder (GB) polyps are tumor or tumor-like projections arising from GB mucosa. Although most polyps are benign, some early GB carcinomas present as polypoid lesions. The diagnosis of GB polyps is relatively easy by ultrasonography. Although numerous studies have investigated GB polyps, few studies have addressed the prevalence of and(More)
BACKGROUND & AIMS Unusual hypervascularity is a hallmark of human hepatocellular carcinoma (HCC). Although microRNA-214 (miR-214) is upregulated in other human cancers, it is downregulated in HCC. We elucidated the biological and clinical significance of miR-214 downregulation in HCC. METHODS MicroRNAs deregulated in HCC were identified using array-based(More)
Recently, applications of mass spectrometry in the field of clinical proteomics have gained tremendous visibility in the scientific and clinical community. One major objective is the search for potential biomarkers in complex body fluids like serum, plasma, urine, saliva, or cerebral spinal fluid. For this purpose, efficient visualization of large data sets(More)
UNLABELLED Intrahepatic metastasis is the primary cause of the high recurrence and poor prognosis of human hepatocellular carcinoma (HCC). However, neither its molecular mechanisms nor markers for its prediction before hepatectomy have been identified. We recently revealed up-regulation of erythroblastic leukemia viral oncogene homolog 3 (ERBB3) in human(More)
BACKGROUND In children, pleural empyema is a recognized complication of severe pneumonia and is characterized by loculated effusions with fibrin septations. The aim of this study was to evaluate the relationship between proinflammatory cytokines [tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), and IL-6], intrapleural fibrinolytic(More)
Guillain-Barré Syndrome (GBS) is a rare autoimmune inflammatory polyneuropathy with a high risk of respiratory failure and unclear pathogenesis. Currently, there are no valid biomarkers for diagnosis of GBS. We used 2-DE and MS to analyze the protein profiles of five pairs of cerebrospinal fluid (CSF) samples of the GBS patients and the patient controls.(More)
Frequent intrahepatic metastasis causes early tumor recurrence and dismaying prognosis of human hepatocellular carcinoma (HCC). We recently identified overexpression of stathmin1 (STMN1) in human HCC. This study was designed to elucidate the clinical and biological significance of overexpression of STMN1 in HCC. Expression of STMN1 was conducted by(More)
