Vimentin expression is a rather rare finding in invasive breast cancer, and is associated with high tumour invasiveness and chemoresistance. It is currently explained by two different biological theories: direct histogenetic derivation from myoepithelial cells, and epithelial-mesenchymal transition (EMT) reflecting the end-stage of breast cancer(More)
The introduction of global gene expression analysis in breast cancer research has focused attention onto a repeatedly described subgroup of invasive breast cancer, the basal-like carcinomas. This subgroup is characterised by the expression of high-molecular weight cytokeratins 5, 14 and 17; using immunohistochemical diagnosis, it represents approximately(More)
The introduction of a concept proposing multiple cellular subgroups in the normal female breast, including cytokeratin 5/6 (Ck 5/6)-positive progenitor cells, offers a new explanation for the existence of highly aggressive breast cancers with and without Ck 5/6 expression. Using the tissue microarray technique, 166 breast cancer cases, all characterized by(More)
Hypoxia and the hypoxia-inducible factor (HIF) transcription factor regulate angiogenic-osteogenic coupling and osteoclast-mediated bone resorption. To determine how HIF might coordinate osteoclast and osteoblast function, we studied angiopoietin-like 4 (ANGPTL4), the top HIF target gene in an Illumina HumanWG-6 v3.0 48k array of normoxic vs. hypoxic(More)
BACKGROUND The endothelin (ET) axis plays a role in cancer biology and plays a potential role as a target for molecular therapy in urogenital tumours. Alterations of several proteins of the ET axis were detected in invasive bladder cancer. OBJECTIVES To examine the potential role of the expression of ET axis proteins compared to other prognostic(More)
In this study, we describe characteristic chromosomal alterations in a consecutive series of 96 serous ovarian tumors by comparative genomic hybridization. We analyze their association with different pathways of progression, histological grade, and clinical outcome. The most striking difference between low-grade and high-grade serous carcinomas was seen in(More)
Clear cell sarcoma of soft tissue (CCSST), also known as malignant melanoma of soft parts, represents a rare lesion of the musculoskeletal system usually affecting adolescents and young adults. CCSST is typified by a chromosomal t(12;22)(q13;q12) translocation resulting in a fusion between the Ewing sarcoma gene (EWSR1) and activating transcription factor 1(More)
PURPOSE To evaluate the relevance of calcifications for invasive breast cancer detection in population-based digital mammographic screening. MATERIALS AND METHODS This study was approved by an independent ethics committee, and no additional informed consent was required. Prospectively documented radiologic cancer features were correlated with pathologic(More)
Several "high throughput methods" have been introduced into research and routine laboratories during the past decade. Providing a new approach to the analysis of genomic alterations and RNA or protein expression patterns, these new techniques generate a plethora of new data in a relatively short time, and promise to deliver clues to the diagnosis and(More)
Gains of chromosomes 7p and 8q are associated with poor prognosis among oestrogen receptor-positive (ER+) stage I/II breast cancer. To identify transcriptional changes associated with this breast cancer subtype, we applied suppression subtractive hybridisation method to analyse differentially expressed genes among six breast tumours with and without(More)
