TOP2A gene copy number change in breast cancer
AIMS The clinical significance of TOP2A as a prognostic marker has not been clarified. The aims of this study were to investigate the frequency of TOP2A copy number change; to correlate TOP2A with HER2 status, hormone receptor (HR) status and molecular subtype, and further to explore differences in breast cancer-specific survival according to TOP2A and HER2. METHODS In this study, TOP2A, HER2...
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 کاملMechanisms of copy number variation and hybrid gene formation in the KIR immune gene complex
The fine-scale structure of the majority of copy number variation (CNV) regions remains unknown. The killer immunoglobulin receptor (KIR) gene complex exhibits significant CNV. The evolutionary plasticity of the KIRs and their broad biomedical relevance makes it important to understand how these immune receptors evolve. In this paper, we describe haplotype re-arrangement creating novel loci at ...
متن کاملGene copy-number polymorphism in nature.
Differences between individuals in the copy-number of whole genes have been found in every multicellular species examined thus far. Such differences result in unique complements of protein-coding genes in all individuals, and have been shown to underlie adaptive phenotypic differences. Here, we review the evidence for copy-number variants (CNVs), focusing on the methods used to detect them and ...
متن کاملProcesses of copy-number change in human DNA: The dynamics of -globin gene deletion
Ectopic recombination between locally repeated DNA sequences is of fundamental importance in the evolution of gene families, generating copy-number variation in human DNA and often leading to pathological rearrangements. Despite its importance, little is known about the dynamics and processes of these unequal crossovers and the degree to which meiotic recombination plays a role in instability. ...
