Project description:3 fresh frozen Breast tumor from the University of North Carolina at Chapel Hill (UNC) were obtained from the UNC Tissue Procurement Facility under an IRB approved protocol. Each experimental sample was ssayed versus a common reference sample that was a modified version of the Stratagene Human Universal Reference (which was further augmented with a 1/10 amount of MCF7 mRNA and 1/10 amount of ME16C mRNA) Keywords = Agilent microarray Keywords = EGFR Keywords = keratin Keywords: parallel sample

Project description:Patient selection and specimen collection. Thirty-six freshly frozen tumor samples were prospectively collected from patients undergoing surgery or biopsy for HNSCC at the University of North Carolina (UNC) at Chapel Hill (21 patients) and Vanderbilt University (15 patients). All tissues were snap-frozen in liquid nitrogen within 30 minutes of surgical resection or biopsy, and kept at -80oC until further processing. All patients consented to participation in this study under protocols approved by IRB at the two institutions. This set includes the samples previously deposited into GEO including 8 additional samples and adjustment for protocol changes. The original 36 before protocol changes (and thus unadjusted) are here: Slebos RJ, Yi Y, Ely K, et al. Gene expression differences associated with human papillomavirus status in head and neck squamous cell carcinoma. Clin Cancer Res 2006;12(3 Pt 1):701-9. Keywords: disease state analysis

Project description:60 fresh frozen HNSCC from the University of North Carolina at Chapel Hill (UNC) were obtained from the UNC Tissue Procurement Facility under an IRB approved protocol. 55 tumor samples were collected from the primary tumor and five tumor samples were collected from a local recurrence at the primary site; one tumor also had a sample of the primary tumor and an associated lymph node metastasis . In addition, we profiled three normal tonsillar epithelium samples that were collected from three pediatric patients following routine tonsillectomy and four HNSCC tumor derived cell lines (UNC7, UMSCCA1, CAL27 and JHU022). Each experimental sample (tumor, normal or cell line) was assayed versus a â??common referenceâ?? sample that was a pool of total RNA derived from 30 of the HNSCC samples. This tumor pool reference strategy has been successfully used in another profiling study. In total, 78 experiments were performed, which utilized three separate preparations of the common reference pool.

Project description:This study began with 72 male 4-week-old BALB/c mice. The mice were split evenly into one of four cohorts: Control, River, Pine, and Road. The control mice were raised with standard corn cob bedding whereas the remaining mice were raised with clean bedding amended with 300 mL of one of three different types of soil. The soil exposure continued throughout the experiment, with 300 mL of new soil added with bi-weekly cage changes. The soils used to amend the cage bedding were previously characterized as having high (Pine), medium (River), and low (Road) diversity. The River and Pine soil were collected from Duke Forest and the Road soil was collected adjacent to Highway 15-501 in Chapel Hill, North Carolina. All mice were given a standard diet and the cages were distributed reverse osmosis treated water through a centralized Lixit® system that was fed to each cage in parallel. After 32 days of standard rearing with amended soils, the mice were exposed via oropharyngeal aspiration to either live influenza A (PR8) virus or heat inactivated (HI) virus.

Project description:This project is intended to study the metabolic adaptation of Methicillin-Resistant Staphylococcus aureus (MRSA) to host immunity. Because of the nature of the samples RTI RCMRC worked with Dr. Anthony R. Richardson so that the samples would be extracted at the University of North Carolina at Chapel Hill under the condition that were optimized by RTI RCMRC for broad spectrum metabolomics analysis.
