Laminin is the main non-collagenous glycoprotein found in the basement membrane. The various laminin isoforms are involved in many physiological and pathological processes, including cancer dissemination. The interaction of cancer cells with laminin was identified as a key event in tumor invasion and metastasis. Laminin effects are mediated by laminin(More)
A genomewide technology, digital karyotyping, was used to identify subchromosomal alterations in ovarian cancer. Amplification at 11q13.5 was found in three of seven ovarian carcinomas, and amplicon mapping delineated a 1.8-Mb core of amplification that contained 13 genes. FISH analysis demonstrated amplification of this region in 13.2% of high-grade(More)
Although in vitro models have been a cornerstone of anti-cancer drug development, their direct applicability to clinical cancer research has been uncertain. Using a state-of-the-art Taqman-based quantitative RT-PCR assay, we investigated the multidrug resistance (MDR) transcriptome of six cancer types, in established cancer cell lines (grown in monolayer,(More)
BACKGROUND Recent work has suggested a role for nuclear factor kappaB (NF-kappaB) in the propagation of ovarian cancer cell lines, but the significance and mechanism of NF-kappaB in ovarian cancer is unknown. The authors hypothesized that the NF-kappaB pathway is over activated in aggressive ovarian cancers. METHODS The levels of 3 NF-kappaB transcription(More)
BACKGROUND Germline mutations in the BRCA1 and BRCA2 genes are known to be associated with an increased risk of breast and epithelial ovarian cancers. Two specific mutations, 185delAG-BRCA1 and 6174delT-BRCA2, have been detected in a substantial proportion (20%-60%) of unselected Ashkenazi Jewish patients--i.e., Jewish patients of Eastern/Northern European(More)
A comprehensive pathological report is essential for optimal patient management, cancer staging and prognostication. In many countries, proforma reports are used but these vary in their content. The International Collaboration on Cancer Reporting (ICCR) is an alliance formed by the Royal College of Pathologists of Australasia, the Royal College of(More)
The object of this study was to analyze the potential association between the expression of MMP-2, MMP-9, MT1-MMP and TIMP-2, and disease outcome in advanced-stage ovarian carcinomas. Sections from 70 paraffin-embedded blocks (36 primary ovarian carcinomas and 34 metastatic lesions) from 45 patients diagnosed with advanced stage ovarian carcinomas (FIGO(More)
Improved insight into the molecular characteristics of the different ovarian cancer subgroups is needed for developing a more individualized and optimized treatment regimen. The aim of this study was to a) identify differentially expressed miRNAs in high-grade serous ovarian carcinoma (HGSC), clear cell ovarian carcinoma (CCC) and ovarian surface epithelium(More)
PURPOSE The purpose of this study was to analyze the expression of the high- and low-affinity nerve growth factor (NGF) receptors TrkA and p75 in effusions and in primary and metastatic tumors of serous ovarian carcinoma patients, as well as to evaluate their association with clinicopathological parameters and disease outcome. EXPERIMENTAL DESIGN Sections(More)
Apolipoprotein E (ApoE) has been recently identified as a potential tumor-associated marker in ovarian cancer by serial analysis of gene expression. ApoE has long been known to play a key role in lipid transport, and its specific isoforms may participate in atherosclerogenesis. However, its role in human cancer is not known. In this study, apoE expression(More)
