Comparative Genomic Hybridization for Molecular Cytogenetic Analysis of Solid Tumors

TLDR
Comparative genomic hybridization produces a map of DNA sequence copy number as a function of chromosomal location throughout the entire genome, which identified 16 different regions of amplification, many in loci not previously known to be amplified.
Abstract
Comparative genomic hybridization produces a map of DNA sequence copy number as a function of chromosomal location throughout the entire genome. Differentially labeled test DNA and normal reference DNA are hybridized simultaneously to normal chromosome spreads. The hybridization is detected with two different fluorochromes. Regions of gain or loss of DNA sequences, such as deletions, duplications, or amplifications, are seen as changes in the ratio of the intensities of the two fluorochromes along the target chromosomes. Analysis of tumor cell lines and primary bladder tumors identified 16 different regions of amplification, many in loci not previously known to be amplified.

Cell cycle control and cancer

TL;DR: New insights in understanding of the cell cycle reveal how fidelity is normally achieved by the coordinated activity of cyclin-dependent kinases, checkpoint controls, and repair pathways and how this fidelity can be abrogated by specific genetic changes.

A multigenic program mediating breast cancer metastasis to bone.

TL;DR: Overexpression of this bone metastasis gene set is superimposed on a poor-prognosis gene expression signature already present in the parental breast cancer population, suggesting that metastasis requires a set of functions beyond those underlying the emergence of the primary tumor.

Circular binary segmentation for the analysis of array-based DNA copy number data.

TL;DR: A modification ofbinary segmentation is developed, which is called circular binary segmentation, to translate noisy intensity measurements into regions of equal copy number in DNA sequence copy number.

TL;DR: A model for the genetic basis of colorectal neoplasia that includes the following salient features is presented, which may be applicable to other common epithelial neoplasms, in which tumors of varying stage are more difficult to study.

Allelotype of Breast Cancer: Cumulative Allele Losses Promote Tumor Progression in Primary Breast Cancer

TL;DR: Analysis of the loss of heterozygosity for each autosomal chromosome arm suggests that at least 4 tumor suppressor genes exist on chromosomes 13q, 16q, and 17p for primary breast cancer.

Oncogene amplification in tumor cells

TL;DR: This chapter summarizes the third mechanism of oncogene activation—oncogene amplification, and illustrates the various ways by which the oncogenic potential of different proto-oncogenes can be activated.

Amplification of cellular oncogenes: a predictor of clinical outcome in human cancer.

TL;DR: Evidence is emerging that amplification may be an early event involved in a more malignant form of this cancer and it is unclear at which stage amplification plays a role in other cancers.
