Evaluation 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 Alterations in Glioma Cell Lines
Established tumor-derived cell lines are widely and routinely used as in vitro cancer models for various kinds of biomedical research. The easy management of these cell cultures, in contrast to the inherent difficulty in establishing and mantaining primary tumoral cultures, has contributed to the wide use of these inmortalized cell lines in order to characterize the biological significance of s...
متن کاملFunctional Copy-Number Alterations in Cancer
Understanding the molecular basis of cancer requires characterization of its genetic defects. DNA microarray technologies can provide detailed raw data about chromosomal aberrations in tumor samples. Computational analysis is needed (1) to deduce from raw array data actual amplification or deletion events for chromosomal fragments and (2) to distinguish causal chromosomal alterations from funct...
متن کاملEstimation of Copy Number Alterations from Exome Sequencing Data
Exome sequencing constitutes an important technology for the study of human hereditary diseases and cancer. However, the ability of this approach to identify copy number alterations in primary tumor samples has not been fully addressed. Here we show that somatic copy number alterations can be reliably estimated using exome sequencing data through a strategy that we have termed exome2cnv. Using ...
متن کاملBIRC5 Genomic Copy Number Variation in Early-Onset Breast Cancer
Background: Baculoviral inhibitor of apoptosis repeat-containing 5 (BIRC5) gene is an inhibitor of apoptosis that expresses in human embryonic tissues but it is absent in most healthy adult tissues. The copy number of BIRC5 has been indicated to be highly increased in tumor tissues; however, its association with the age of onset in breast cancer is not well understood. Methods: Forty tumor tiss...
