Identification of homogeneously staining regions in leukemia patients

Homogeneously staining regions (HSR) or double minute chromosomes (dmin) are autonomously replicating extra-chromosomal elements that are frequently associated with gene amplification in a variety of cancers. The diagnosis of leukemia patients was based on characterization of the leukemic cells obtained from bone marrow cytogenetics. This study report two cases, one with Acute Myeloblastic Leuk...

Homogeneously staining regions in direct preparations from human neuroblastomas.

Previous descriptions of homogeneously staining regions in human neuroblastomas have been in karyotypes obtained from established cell lines. We now report homogeneously staining regions in direct preparations from two human neuroblastomas. In one of the cases, the homogeneously staining region identified in the primary tumor was also found in metastases to bone marrow and pleural fluid. The ho...

Homogeneously Staining Regions in Direct Preparations from Human Neuroblastomas1

Previous descriptions of homogeneously staining regions in human neuroblastomas have been in karyotypes obtained from established cell lines. We now report homogeneously staining regions in direct preparations from two human neuroblastomas. In one of the cases, the homogeneously staining region iden tified in the primary tumor was also found in métastases to bone marrow and pleural fluid. The ...

Genomic organization and evolution of double minutes/homogeneously staining regions with MYC amplification in human cancer

The mechanism for generating double minutes chromosomes (dmin) and homogeneously staining regions (hsr) in cancer is still poorly understood. Through an integrated approach combining next-generation sequencing, single nucleotide polymorphism array, fluorescent in situ hybridization and polymerase chain reaction-based techniques, we inferred the fine structure of MYC-containing dmin/hsr amplicon...
