A predisposition to colorectal cancer is shown to be linked to markers on chromosome 2 in some families. Molecular features of "familial" cancers were compared with those of sporadic colon cancers. Neither the familial nor sporadic cancers showed loss of heterozygosity for chromosome 2 markers, and the incidence of mutations in KRAS, P53, and APC was(More)
Classification of human tumors according to their primary anatomical site of origin is fundamental for the optimal treatment of patients with cancer. Here we describe the use of large-scale RNA profiling and supervised machine learning algorithms to construct a first-generation molecular classification scheme for carcinomas of the prostate, breast, lung,(More)
Human tumorigenesis is associated with the accumulation of mutations both in oncogenes and in tumour suppressor genes. But in no common adult cancer have the mutations that are critical in the early stages of the tumorigenic process been defined. We have attempted to determine if mutations of the APC gene play such a role in human colorectal tumours, which(More)
Knowledge of the patterns of allelic loss has been useful in identifying the spectrum of the tumor suppressor genes involved in various tumor types. Such analyses in pancreatic carcinoma have been difficult due to the characteristic host desmoplastic reaction to the neoplasm. We have assembled the first allelotype of pancreatic adenocarcinoma, a survey for(More)
The E2F group of transcription factors transactivates genes that promote progression through the G1-S transition of the cell cycle. Members of the retinoblastoma (Rb) family of proteins bind to E2Fs and inhibit this function. E2F-4, one example of the E2F group, functions as an oncogene when transfected into nontransformed cells in vitro. On the other hand,(More)
Allelic loss of chromosome 8p21-22 occurs frequently in cancer, including lung and head and neck squamous cell cancer. The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) receptors, including proapoptotic DR4 and KILLER/DR5, are located on 8p21-22. TRAIL receptors are candidate tumor suppressor genes, because their inactivation would be(More)
Gastric adenocarcinoma is a leading cause of cancer mortality world-wide. Yet, the underlying molecular events important in the development of this cancer are largely undefined. Thus, we performed a comprehensive survey for allelic loss on our panel of xenografted human gastric carcinomas. Contaminating normal stromal cells of primary cancers often limit(More)
Despite 1.2 billion ambulatory visits in 2005, from a health care quality and safety perspective, the ambulatory setting has been less subject to research and scrutiny, compared to high-risk inpatient areas like surgery, perioperative and perinatal care, and the emergency department (ED). The ambulatory environment is prone to problems and errors that(More)
An automated data archival and retrieval system has been designed, developed, and implemented to improve the management of aeropropulsion test data at the Arnold Engineering Development Center (AEDC). Previously, the data archival and retrieval involved a laborious process that included manual tape operations and record keeping. The Test Data Management(More)
Bacterial disease is a significant issue for larviculture of several species of shellfish, including oysters. One source of bacteria is the seawater used throughout the hatchery. In this study carried out at a commercial oyster hatchery in Tasmania, Australia, the diversity of the bacterial community and its relationship with larval production outcomes were(More)
