Project description:High-grade serous ovarian cancer is the most aggressive histological type of epithelial ovarian cancer, which is characterized by a high frequency of somatic TP53 mutations. To provide a better understanding of the molecular mechanisms involved in the pathogenesis of these cancers and to develop a risk classification system, we conducted profiling of the copy number alterations present in these tumors. Thirty patients who were diagnosed as high-grade serous ovarian cancer were recruited in this study. Affymetrix SNP array were performed according to the manufacturer's directions on DNA extracted from high-grade serous ovarian cancer tissues or peripheral blood samples.

Project description:Copy number and LOH analysis was performed for 56 chronic myeloid leukemia cases obtained from 23 CML cases obtained atchronic phase, accelerated phase, blast crisis, or remission. All caseswere genotyped with Affymetrix 250k Sty and Nsp arrays.

Project description:B cell non-Hodgkin's lymphoma (B-NHL) consists of different pathological entities that are frequently characterized by distinct genetic alterations. However, the knowledge on these genetic lesions in B-NHL is still limited. In order to obtain a more comprehensive view of genetic lesions in B-NHL, we performed genome-wide analysis of copy number (CN) alterations as well as allelic imbalances using Affymetrix SNP arrays with B-NHL cases, including SNP array data were analyzed with CNAG/AsCNAR software, which enabled sensitive detection of CN alterations in allele-specific manner, and thus allelic imbalances, without depending on availability of paired normal controls. Most frequent numerical abnormalities in B-NHL were gains of chromosomes 3 and 18, although gains of chromosome 3 were less prominent in FL. Chromosomal deletions that lead to loss of heterozygosity (LOH) were commonly found in 1p, 6q and 10q. High-grade amplifications and homozygous deletions frequently provide a clue to identify relevant gene targets. In our series, 12 loci of high-grade amplifications and 14 loci of homozygous deletions were identified, and helped to specify the candidate genes. These regions included, FCGR2B amplified in 5 cases of DLBCL, RERE amplified in 2 cases of FL and CDKN2A/CDKN2B deleted in 9 cases of DLBCL.

Project description:This dataset was applied to evaluate the performance of a deep learning framework, FFPERescuer, specifically designed to reconstruct gene expression profiles from RNA sequencing data derived from FFPE (formalin-fixed, paraffin-embedded) tumor tissues. The dataset includes a total of 12 RNA-Seq samples, comprising 10 FFPE tumor tissue samples from colorectal cancer (CRC) cases collected in Amsterdam, the Netherlands, with 2 duplicate samples included for reproducibility assessment. The corresponding gene expression profiles from fresh-frozen tumor tissues for these 10 cases are available in the dataset GSE33113, generated using microarray technology.

Project description:The JGOG3025 study was conducted by the Japanese Gynecologic Oncology Group (JGOG) on 710 patients with epithelial ovarian cancer (NCT03159572). In the JGOG3025-TR2 study, fresh frozen tumor tissues from 274 and 15 cases diagnosed as stage II or higher high-grade serous carcinoma (HGSC) or high-grade endometrioid carcinoma (HGEC) in the central pathological review were submitted to SNP array, total RNA-sequencing, and DNA methylation array analyses.
