Project description:167 Ull-samples 244k array Tumor tissue from a series of 212 primary breast cancers were sequentially collected at Ullevål University Hospital, Oslo, Norway between 1990 and 1994. Tissues were collected at the time of primary surgery and snap frozen. We performed aCGH on 167 of these samples. DNA was isolated using chloroform/phenol extraction, followed by ethanol precipitation. The aCGH-platform was the Agilent Human genome CGH Microarray 244k. The aim of this study was to investigate the genome wide genomic copy number alterations in a cohort of primary breast cancer patients.
Project description:Expression profiling of 70 Pancreatic Ductal Adenocarcinoma (PDAC) samples was performed on Agilent 44K expression arrays for cancer gene discovery. Additionally, matched aCGH on Agilent 244K arrays was performed. These two datasets were integrated in order to identify driver mutations leading to pancreatic cancer. Promising candidates were interrogated further using functional studies.
Project description:Copy number alteration (CNA) is a good signpost to identify cancer related genes. CNAs were analyzed using the Agilent 244K array comparative genomic hybridization (aCGH) in fresh-frozen tumor and matched normal tissues from 10 gastric cancer patients.
Project description:Array Comparative Genomic Hybridization (aCGH) of 70 pancreatic ductal adenocarcinoma (PDAC) samples was performed on Agilent 244K CGH arrays in order to find common genomic aberrations for cancer gene discovery. Additionally, matched expression profiling on Agilent 44K arrays was performed. Common copy number aberrations were identified in order to identify a list of putative cancer genes. Expression profiling data was used to further enrich this list of putative cancer genes for more likely candidates. Last, the most promising candidates were functionally interrogated using RNA interference-mediated knockdown to mimic loss. Well-known PDAC cancer genes were observed as amplified (KRAS and MYC) and deleted (CDKN2A, TGFBR2, SMAD4, and MAP2K4).
Project description:High resolution aCGH was performed on 10 primary Desmoplastic Melanomas (DMs). DMs are a rare subtype of melanoma known for their pronounced desmoplastic stroma and spindled melanocytes. 10 samples were hybridized to Agilent 1 Million feature two color arrays as compared to a panel of normal male DNA. 6 samples were hybridized to Agilent 244K feature two color arrays as compared to a panel of normal male DNA. 34 samples were hybridized to Agilent 180K feature two color arrays as compared to a panel of normal male DNA.
