Array CGH containing 4,044 human bacterial artificial chromosome clones was used to assess different copy number changes between chemotherapy responsive and non-resposive breast cancer tissues.
Project description:In this study, we investigated CNAs of 59 tumor samples from 27 patients with submucosal-invasive gastric cancers (SMGC) by 44k oligonucleotide-based array comparative genomic hybridization (array CGH).
Project description:Genomic DNA from sporadic breast tumours was isolated and analysed using array CGH. The NKI 1MB BAC/PAC micro array was used to identify chromosomal aberrations of all tumours. Other profiles are located at: GSE9114 Keywords: sporadic breast tumour, CGH.
Project description:This study is designed to find a reliable marker enabling to predict the response to treatment in patients with early breast cancers treated by neoadjuvant chemotherapy. This marker would allow on one hand to select more homogeneous patient cohorts requiring treatment escalation strategies, and on the other hand reduce the burden of toxicity (both treatment-related and financial) for the patients that will already derive high benefit from the conventional treatments. In this study, gene expression profiles were measured and correlated with the clinical response to neoadjuvant chemotherapy and other features like the epithelial to mesenchymal transition and the tumor immune cell infiltration.
Project description:In this study, we investigated CNAs of 4 tumor samples from 2 patients, including conventioanl chromophobe renal cell carcinoma(ChRCC), ChRCC with neuroendocrine differentiation and no-tumor region by 44k oligonucleotide-based array comparative genomic hybridization (array CGH).
Project description:DNA copy number profiles can identify patients with a defect in BRCA1 or BRCA2. We previously showed that patients with a BRCA1 like profile benefit from intensified alkylating chemotherapy (IA, 4 cycles 5-fluorouracyl (5FU), epirubicin, cyclophosphamide (C) + 1 cycle carboplatin, thiotepa and cyclophosphamide with autologous stem cell transplantation (ASCT)). Presumably, this is because of the defect in error free homologous recombination DNA repair. Here we present an independent study IA chemotherapy (2 cycles induction, followed by ifosfamide, 12 g/m2; carboplatin, 900 mg/m2; and epirubicin, 180 mg/m2 with ASCT) versus anthracyclin-C (AC) or C-methothrexate-5FU (CMF) regimens in high risk breast cancer. DNA isolated from untreated resection specimens of 117 patients was labeled using Enzo labeling kit for array CGH and hybridized to a custom 135k Nimblegen platform.
Project description:Gene expression profiles of human breast cancer tissues from 100 different patients treated with primary systemic chemotherapy (Gemcitabine, Epirubicin and Docetaxel) Keywords: expression profiling
