To define genetic determinants of tumor cell resistance to the cytotoxic action of tumor necrosis factor ␣ (TNF), we have applied cDNA microar-rays to a human breast carcinoma TNF-sensitive MCF7 cell line and its established TNF-resistant clone. Of a total of 5760 samples of cDNA examined, 3.6% were found to be differentially expressed in TNF-resistant 1001(More)
BACKGROUND The increasing use of DNA microarrays in biomedical research, toxicogenomics, pharmaceutical development, and diagnostics has focused attention on the reproducibility and reliability of microarray measurements. While the reproducibility of microarray gene expression measurements has been the subject of several recent reports, there is still a(More)
BACKGROUND Aneuploidy and chromosomal instability (CIN) are common abnormalities in human cancer. Alterations of the mitotic spindle checkpoint are likely to contribute to these phenotypes, but little is known about somatic alterations of mitotic spindle checkpoint genes in breast cancer. METHODS To obtain further insight into the molecular mechanisms(More)
Non-small cell lung cancer (NSCLC), a leading cause of cancer deaths, represents a heterogeneous group of neoplasms, mostly comprising squamous cell carcinoma (SCC), adenocarcinoma (AC) and large-cell carcinoma (LCC). The objectives of this study were to utilize integrated genomic data including copy-number alteration, mRNA, microRNA expression and(More)
Neither the molecular mechanisms whereby cancer cells intrinsically are or become resistant to the DNA-damaging agent cisplatin nor the signaling pathways that account for cisplatin cytotoxicity have thus far been characterized in detail. In an attempt to gain further insights into the molecular cascades elicited by cisplatin (leading to resistance or(More)
BACKGROUND To identify new molecular markers of bone marrow dissemination in human neuroblastoma (NB), we studied the transcriptome profiles of malignant neuroblasts established from the human MYCN-amplified IGR-N-91 model. METHODS This experimental model includes human neuroblastoma cells derived from a subcutaneous stage 4 disease, myocardium (Myoc) and(More)
Follicular thyroid carcinomas (FTC) arise through on-cogenic pathways distinct from those involved in the papillary histotype. Recently, a t(2;3)(q13;p25) rearrangement , which juxtaposes the thyroid transcription factor PAX8 to the peroxisome proliferator-activated receptor (PPAR) ␥1, was described in FTCs. In this report, we describe gene expression in 11(More)
Gorlin's or nevoid basal cell carcinoma syndrome (NBCCS) causes predisposition to basal cell carcinoma (BCC), the commonest cancer in adult human. Mutations in the tumor suppressor gene PTCH1 are responsible for this autosomal dominant syndrome. In NBCCS patients, as in the general population, ultraviolet exposure is a major risk factor for BCC development.(More)
