CanGEM: mining gene copy number changes in cancer
The use of genome-wide and high-throughput screening methods on large sample sizes is a well-grounded approach when studying a process as complex and heterogeneous as tumorigenesis. Gene copy number changes are one of the main mechanisms causing cancerous alterations in gene expression and can be detected using array comparative genomic hybridization (aCGH). Microarrays are well suited for the ...
متن کاملDNA copy number changes in cervical adenocarcinoma.
PURPOSE There is evidence that specific genetic events are involved in the initiation and progression of squamous cell carcinoma of the uterine cervix. The genotype-phenotype correlations in cervical adenocarcinoma (AC) are unclear. EXPERIMENTAL DESIGN Comparative genomic hybridization was applied to screen for DNA copy number gains and losses in 22 cervical ACs of clinical stage IB. IHC was ...
متن کاملGene expression patterns and gene copy number changes in dermatofibrosarcoma protuberans.
Dermatofibrosarcoma protuberans (DFSP) is an aggressive spindle cell neoplasm. It is associated with the chromosomal translocation, t(17:22), which fuses the COL1A1 and PDGFbeta genes. We determined the characteristic gene expression profile of DFSP and characterized DNA copy number changes in DFSP by array-based comparative genomic hybridization (array CGH). Fresh frozen and formalin-fixed, pa...
متن کاملEvaluation of HER2, MDM2, MYC, MET and TP53 gene copy number alterations in gastric cancer patients
Background: Gastric cancer (GC) is considered as one of the most common types of cancer worldwide with poor prognosis and generally limited treatment options. Recent studies have indicated that HER2, MDM2, MYC, MET, and TP53 play an important role in the development of gastric cancer. Therefore, the aim of this study was to evaluate the incidence of amplification/deletion of these genes in pati...
متن کاملCopy number variants, diseases and gene expression.
Copy number variation (CNV) has recently gained considerable interest as a source of genetic variation likely to play a role in phenotypic diversity and evolution. Much effort has been put into the identification and mapping of regions that vary in copy number among seemingly normal individuals in humans and a number of model organisms, using bioinformatics or hybridization-based methods. These...
