Elevated enhancer-oncogene contacts and higher oncogene expression levels by recurrent CTCF inactivating mutations in acute T cell leukemia [Array CGH]

(Submitter supplied) CCCTC-binding factor (CTCF) regulates the 3D chromatin architecture by facilitating chromosomal loops. In addition to insulation of euchromatin from heterochromatin, CTCF is an important transcription factor and regulator of antigen receptor and T cell receptor recombination events. CTCF inactivating events have been found in human cancer, resulting in deregulation of global gene expression by altered methylated genomic states. more...

High-resolution profiling of copy-number aberrations in osteosarcoma

(Submitter supplied) Osteosarcoma is a rare, highly malignant tumor of the bone that presents with a highly complex and abnormal karyotype. Only a few of the genes, which are targets of genetic alteration are known. An integrated genome-wide genomic and gene expression profiling analysis was performed on human osteosarcoma tissues and osteosarcoma cell lines in order to identify and map, in a high-resolution fashion, the most drastic chromosomal changes and point out genes which could contribute to tumorigenesis by having altered expression levels of critical oncogenes and tumor suppressors. more...

CGH array profiles of melanoma cell lines

(Submitter supplied) Dysfunction in type I interferon (IFN) signaling occurs in patients with stage II or more advanced cancer. After screening the effects of a panel of 12 melanoma cell lines on PBMCs of healthy volunteers of IFNalpha signal pathway, two groups of melanoma cell lines could be identified one with stronger suppression (low pSTAT-1 group) than the other (high pSTAT-1 group). Comparative genomic hybridization (CGH) identified consistent amplification of 12q22-24 as a genomic marker for the immune suppressive melanoma cell lines. more...

Copy number aberrations of genes regulating normal thymus development in thymic epithelial tumors

(Submitter supplied) Thymic epithelial tumors are a group of neoplasms with heterogeneous histological features and clinical behavior. The identification of markers useful to predict patient prognosis and molecular targets for therapies is limited by a very little understanding of the biology of these neoplasms. We evaluated the copy number (CN) aberrations of genes involved in normal thymus development in thymic epithelial tumors, following the intriguing idea that the ectopic deregulation of genes relevant for proliferation and differentiation of embryonic cells, can contribute to tumor growth. more...

High-resolution, genome-wide analysis of human metastatic neuroblastoma samples by array-Comparative Genomic Hybridization (aCGH)

(Submitter supplied) Neuroblastoma (NB) is an aggressive tumor that affects both infants and children. The disease outcome is greatly influenced by age of patient, stage, chromosome copy number aberrations (CNAs) and gene expression abnormalities. We analyzed, by microarray technology, genome and transcriptome of 3 groups of tumors of patients with metastatic disease: G1, stage 4S and MYCN single copy; G2, stage 4 younger than 18 months of age, MYCN single copy with no disease progression and G3, stage 4, older than 19 months, with unfavorable outcome. more...

Genomic aberrations in distant fields from oral potentially malignant lesions by high resolution DNA flow cytometry and array-CGH

(Submitter supplied) The aim of the study was to address the concept of field cancerization in oral cancer. The presence of genomic aberrations, indicative of chromosomal instability (CIN), in oral distant fields (ODFs) of visually normal and non-dysplastic mucosa at the mirror image from concomitant oral potentially malignant lesions (OPMLs) was investigated. This pilot study comprised 16 OPMLs (8 without dysplasia, nd-OPMLs; 8 with dysplasia, d-OPMLs) and 16 ODFs. more...

Chromosomal aberrations and aneuploidy in oral potentially malignant lesions: distinctive features for tongue.

(Submitter supplied) The mucosae of the oral cavity are different at the histological level but are all exposed to common genotoxic agents. As a result of this exposure, changes in the mucosal epithelia develop giving rise to Oral Potentially Malignant Lesions (OPMLs), which with time may in turn progress to Oral Squamous Cell Carcinomas (OSCCs). Therefore, much effort should be devoted to identify features able to predict the likeliness of progression associated with an OPML. more...

Carboxypeptidase of glutamate-like gene as a tumor suppressor in pancreatic cancer cells and a prognostic marker for resected pancreatic cancer patients

(Submitter supplied) Pancreatic cancer is the fourth leading cancer-related death in United States. The clinical relevance of genomic imbalances in pancreatic cancer is uncertain. We performed array-comparative genomic hybridization (aCGH) in 44 resected pancreatic cancer specimens from a Korean cohort. We observed recurrent copy number gains were observed in chromosome 1q, 11q, 18q11.1-11.2, and 20q13.13; and losses in chromosome 2p, 9p, 10q, 14q, 15q, 18q12.2-23, 19q, 20q11.1, 21p, and 22q. more...

Comprehensive array CGH of normal karyotype Myelodysplastic syndrome reveals hidden recurrent and individual genomic copy number aberrations with prognostic relevance

(Submitter supplied) About 40% of patients with myelodysplastic syndromes (MDS) present with a normal karyotype and they are facing different courses of disease. To advance the biological understanding and find molecular prognostic markers we performed a high resolution oligonucleotide array study of 107 MDS patients (FAB) with a normal karyotype. Recurrent hidden deletions overlapping with known cytogenetic aberrations or sites of known tumor associated genes were identified in 4q24 (TET2, 2x), 5q31.2 (2x), 7q22.1 (3x) and 21q22.12 (RUNX1, 2x). more...

Array CGH analysis of human gastrointestinal stromal tumors

(Submitter supplied) Gastrointestinal stromal tumors (GISTs) are the most important mesenchymal tumors of the gastrointestinal tract. The vast majority of GISTs exhibit activating mutations of KIT or PDGFRA, but epigenetic alteration of GISTs is largely unknown. In this study, we aimed to clarify the involvement of DNA methylation in GIST malignancy. A total of 25 GIST specimens were studied using Human Genome CGH Microarray Kit 105A (G4412A, Agilent). more...

Array CGH-based Characterization of Genetic Alterations in Pulmonary Neuroendocrine Tumors

(Submitter supplied) The goal of this study was to characterize and classify pulmonary neuroendocrine tumors based on Array Comparative Genomic Hybridization (aCGH). Using aCGH, we performed karyotype analysis of 33 small cell lung cancer (SCLC) tumors, 13 SCLC cell lines, 19 bronchial carcinoids, and 9 gastrointestinal (GI) carcinoids. In contrast to the relatively stable karyotypes of carcinoid tumors, the karyotypes of SCLC tumors and cell lines were highly aberrant. more...
