This study is to investigate the correlation between urine metabolites and clinical staging in patients with ovarian cancer. The urina sanguinis from 56 cases of primary epithelial ovarian cancer patients and 15 healthy volunteers was collected and the urine metabolites were extracted. Ultra high performance liquid chromatography/time-of-flight mass spectrometry (UPLC-Q-TOF-MS) analysis was performed. Principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were used to analyze the mass spectrometry data. Database retrieval and comparison of the screened metabolites were performed and one-way ANOVA and least significant dif­ference (LSD) t test were carried out. PCA analysis of UPLC-Q-TOF-MS results showed that the score plots of samples from healthy people and patients with ovarian cancer at different clinical stages were separated. Further PLS-DA analysis significantly improved the classification results. The R2X was 0.757, the R2Y was 0.977 and the Q2Y was 0.87, indicating that the model stability and predictability were good. Eight metabolites, including N-acetylneuraminic acid-9-phosphate, 5’-methioadenosine, uric acid-3-nucleoside, pseudouridine, L-valine, succinic acid, L-proline and β-nicotinamide mononucleotide were identified. The contents of these metabolites increased with the development of the disease. There was correlation between urine metabolites and clinical staging in patients with ovarian cancer. © 2015, E-Century Publishing Corporation. All rights reserved.

Recently, ETS-related gene (ERG) gene rearrangements, phosphatase tensin homologue (PTEN) deletions and EGFR family aberrations were characterized as potential biomarkers for prostate cancer (PCa) patient management. Although ERG gene rearrangement has been identified in approximately 50% of localized prostate cancers in western countries, the prognostic significance of this critical molecular event remains unknown in Chinese patients. Using fluorescence in situ hybridization (FISH) and immunohistochemistry, we evaluated ERG, PTEN and EGFR family aberrations in a cohort of 224 Chinese prostate cancer patients diagnosed in transurethral resection of the prostate (TUR-P). Overall, ERG rearrangement was detected in 23.2% (44/190) cases, of which 54.5% (24/44) showed deletion of the 59end of ERG. PTEN deletion was identified in 10.8% (19/176) cases. Amplification of EGFR and HER2 genes was present in 1.1% (2/178) and 5.8% (10/173) of cases, respectively. Significant correlation between ERG rearrangement and PTEN deletion was identified in this cohort. EGFR and HER2 aberrations occurred more frequently in PCas without ERG rearrangement than in those with ERG rearrangement, although this did not reach statistical significance. Overall, ERG rearrangement was associated with pre-operative PSA values (P = 0.038) and cancer-related death (P = 0.02), but not with the age, clinical T stage, Gleason score, or Ki-67 labeling index (LI). Notably, multivariate analysis including known prognostic markers revealed ERG rearrangement was an independent prognostic factor (P = 0.022). Additionally, ERG rearrangement status was helpful to identify patients with poor prognosis from PCa group with low Ki-67 LI. In summary, we reported that ERG rearrangement was associated with cancer-related death in Chinese PCa patients. Determination of ERG rearrangement status allows stratification of PCa patients into different survival categories. © 2014 Qi et al.

OBJECTIVE: Umbilical mesenchymal stem cells (UMSCs) is one of most popular regenerative medical source of bone replacement therapy in both clinical and scientific researches. However, it is still low effective to induce the osteogenesis of hUMSCs. In this study, we aimed to elucidate the roles of DNA methyltransferase 3B (DNMT3B) in the osteogenesis of hUMSCs. MATERIALS AND METHODS: Knockdown DNMT3B in hUMSCs was gained via RNA interference technology. After confirming the decrease of DNMT3B in mutant hUMSCs by immunostaining and qPCR, osteogenesis differentiation was carried out. To identify the phenotype of osteogenesis in both bone formation ability and function of bone, immunostaining, qPCR and functional test was performed, compared to wildtype hUMSCs. RESULTS: Real-time Quantitative PCR (qPCR) and immunostaining results indicated that lacking of DNTM3B the osteogenesis related genes were significantly downregulated. Meanwhile, the functional test was also consistent with the downregulated differentiation result. CONCLUSIONS: The osteogenesis differentiation of hUMSCs is impaired in the absence of DNMT3B.

c-Met plays an important role in colorectal tumorigenesis and disease progression and thus is believed to be an attractive inhibitory target for receptor molecular therapeutic. SU11274 was identified as a small molecule, ATP competitive inhibitor of the catalytic activity of the c-Met kinase. Our study had investigated the relationship between the high expression of c-Met and colorectal carcinoma and the effect of c-Met inhibitor SU11274 in colorectal carcinoma in vitro and vivo. Immunohistochemistry was used to detect the expression of c-Met in 60 patients with colorectal cancer and 20 patients with benign adenoma and surrounding normal colon tissues. The effect of SU11274 on human colorectal carcinoma LoVo cells was detected by Western blot and MTT. And the influence of SU11274 on cell cycle was determined by flow cytometry. In addition, LoVo cell-transplanted tumor growth and expression of c-Met in nude mice was examined for inhibition of SU11274 in vivo. We found c-Met had high expression and was closely related to lymph node metastasis and TNM stage in colorectal carcinoma tissues. SU11274 significantly suppressed the phosphorylation of c-Met as well as the survival and proliferation of LoVo cell lines. G1-phase arrest was also induced by SU11274. SU11274 apparently restrained the growth of the xenograft tumor in nude mice. Our data suggest developing therapies that specifically inhibit the activation of c-Met may represent a novel therapeutic modality for patients with colorectal carcinoma expressing high levels of c-Met. © 2013 Springer Science+Business Media New York.

Human LIGHT (lymphotoxin-related inducible ligand that competes for glycoprotein D binding to herpesvirus entry mediator on T cells) is the 14th member of the tumor necrosis factor (TNF) superfamily and is therefore also known as TNFSF14. LIGHT has been proven to be a multifunctional molecule affecting cell proliferation, differentiation and a number of other biological processes, in particular, cell growth inhibition. However, the expression and molecular mechanisms of the LIGHT gene in human colorectal carcinoma cells remain largely unclear. In the present study, the LIGHT gene was overexpressed using a lentiviral expression vector in HCT116 human colorectal carcinoma cells in vitro and in vivo, in order to explore the mechanism by which the LIGHT gene inhibits cell growth and suppresses tumor formation. The results showed that the recombinant lentivirus with LIGHT overexpression inhibited the proliferative capacity of the HCT116 cells and significantly decreased the xenografted tumor volumes in nude mice. Furthermore, LIGHT treatment effectively initiated increased caspase-3 and decreased Bcl-2 activities in the HCT116 cells. This study provides a basis for the improved understanding of the role and molecular mechanisms of the LIGHT gene in human colorectal carcinoma cells and may facilitate further functional studies of LIGHT.
