ABSTRACT: To study the field cancerization effect, we screened systemic metastasis-related CNVs from morphologically normal colon tissues adjacent to colon cancer that had systemic metastasis. 89 systemic metastasis-related CNVs, mainly consisting of migration and invasion-, morphology-, cell death and survival-related pathways, were selected. Noticeably, LIM and senescent cell antigen-like domains 2 (LIMS 2, PINCH2) showed copy number amplification and up-regulation of mRNA expression in the non-relapsed group compared to the systemic relapse group. Colon cancer cells had lower expression of PINCH2 protein and mRNA compared with normal epithelial colon cells. Two-condition experiment: 41 colon normal tissue vs. control gDNA.

Project description:To identify novel genetic causes of congenital kidney anomalies(KA), we performed a whole genome copy number variation (CNV) detection in 62 patients with KA using Agilent SurePrint G3 Human CGH Microarray Kit (1x1M). Agilent sex-matched human DNA was used as reference. Data were extracted using Agilent Feature Extraction software v10.7 and CNVs were called using the ADM-II algorithm with a threshold of 6.0 in Agilent CytoGenomics software v5.0. With a systematic analysis, we identified 10 known or novel genomic imbalances in 9 (14.5%) cases.
Project description:Human hepatocarcinomas (HCCs) of different histological grades and tumour-adjacent non-neoplastic liver tissues (FFPE samples of surgical specimens) were analysed by array-based comparative genomic hybridization (aCGH) versus human male genomic DNA to identify high-frequency chromosomal aberrations in the tumors and initial chromosomal imbalances in the tumor-adjacent non-neoplastic liver tissues.
Project description:The aim of the study was to identify molecular mechanisms involved in high risk diffuse large B-cell lymphomas (diffuse large B-cell lymphomas). <br>51 prospectively collected tumor samples from the patients treated in the Nordic phase II study with dose-dense chemoimmunotherapy followed by systemic CNS prophylaxis were analyzed by high resolution array comparative genomic hybridization (aCGH). <br>The aCGH data were combined with the transcriptomics information from the exon array and the data associated with survival.
Project description:To reveal the risk CNVs of SZ in Chinese population, we recrited and enrolled 100 Chinese family trios with a schizophrenia affected children and both of their father and mother. SZ was diagnosed according to DSM-IV criteria by two independent psychiatrists. There gDNA we screen the genome-wide CNV using Agilent SurePrint G3 Human CGH Microarray Kit (1x1M) and Agilent sex-matched human DNA was used as reference. The CNV were called by ADM-2 statistical algorithms with a threshold of 6.0. We compared the burden of large rare CNVs and found that SZ probands carried more duplications and less deletions. Furtherly, we performed familial inheritance analysis of transmission disequilibrium and de novo CNV detection, validated several associated CNV loci with SZ susceptibility and also identify eight novel loci conferring risk of SZ
Project description:Anti-cancer drugs, particularly doxorubicin may trigger alterations in the copy numbers of genes. The data present the results of array comperative genomic hybridization of two different MCF-7 cell lines that are resistant to diverse concentration of the doxorubicin in the presence of the sentive control. Although the submission options were chosen as SurePrint G3 Human CGH Microarray 8x60K (G4450A; Agilent Technologies, USA) for all data, a resistant cell line, so called aCGH_400DOX, was studied by the GenetiSure Cyto 8 x 60K CGH Microarrays (G5982A; Agilent Technologies, USA). The results underlined that resistance to the doxorubicin at diverse drug dosages critically altered the copy numbers of some of the fundamental genes.

Project description:Melanoma is one of the most aggressive and treatment-resistant cancers. It represents the most life-threatening neoplasm of the skin, and its incidence has been increasing for the last three decades. Melanoma evolves from the local transformation of melanocytes to primary tumors, which can metastasize to multiple organs. Brain metastases represent one of the most significant causes of death in cutaneous melanoma patients. Despite aggressive multi-modality threapy, patients with melanoma brain metastasis have a median survival of less than a year, with a majority of these patients dying as a result of their intracranial disease. We aimed to find brain metastasis-specific molecular markers. To identify alterations in DNA methylation related to brain metastasis, we used Illumina 450K BeadChips to assess differentially methylated regions in melanocytes, primary melanomas, lymph node metastases, and brain metastases. Bisulphite-converted DNA from 40 specimens was hybridised to the Illumina Infinium 450k Human Methylation BeadChip.
