Project description:From ~1,700 non-small cell lung cancer specimens collected at the MD Anderson Cancer Center over the years 1997 to 2005, we selected 914 tumors with detailed clinical and pathological information. We extracted RNA and DNA from frozen tissues using histology quality control from 700 cases. RNA was examined for quality using Agilent Bioanalyzer and RNA integrity number (RIN) was obtained for all specimens. A final selection of 275 tumor specimens was based on the following criteria: 1) Select mainly adenocarcinomas (n = 183) and squamous carcinomas (n = 80); 2) Tissue material contains at least 70% tumor by section examination; 3) within the tumor section, there should be at least 30% tumor cells (as opposed to stromal cells); 4) RIN should be at least 4.0 (range 0 - 10). Various profiling experiments were then performed including mRNA expression (this study), miRNA profiling, aCGH (Agilent), Reverse-phase protein array (RPPA), mutation analysis of 20 genes (Sequenom) and MS-MALDI-TOFF analysis. 275 lung cancer specimens collected at the MD Anderson Cancer Center were profiled on Illumina WG6-V3 expression arrays. Detailed clinico-pathological information were also collected.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:1,322 morphologically unidentified fragmentary bone specimens were analyzed using MALDI-TOF and a subset of 341 bone specimens with LC-MS/MS in order to characterize their proteome for species identification and potential hominin specimens related to the LRJ transitional period derived from the site Ilsenhöhle Ranis, Germany (50°39.7563’N, 11°33.9139’E).
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs. One-condition experment, gene expression of 3A6
Project description:41 lung adenocarcinoma from never-smokers hybridized on Illumina SNP arrays on 13 HumanCNV370-Quadv3 chips. High-resolution array comparative genomic hybridization analysis of lung adenocarcinoma in 41 never smokers for identification of new minimal common regions (MCR) of gain or loss. The SNP array analysis validated copy-number aberrations and revealed that RB1 and WRN were altered by recurrent copy-neutral loss of heterozygosity.The present study has uncovered new aberrations containing cancer genes. The oncogene FUS is a candidate gene in the 16p region that is frequently gained in never smokers. Multiple genetic pathways defined by gains of MYC, deletions of RB1 and WRN or gains on 7p and 7q are involved in lung adenocarcinoma in never smokers. A 'Cartes d'Identite des Tumeurs' (CIT) project from the French National League Against Cancer (http://cit.ligue-cancer.net) 41 samples hybridized on Illumina SNP arrays.
