Deciphering the molecular basis of cancer is critical for developing novel diagnostic and therapeutic strategies. To better understand the early molecular events involving osteogenic sarcoma (OGS), we have initiated a program to identify potential tumor suppressor genes. Expression profiling of total RNA from ten normal bone cell lines and eleven OGS-derived cell lines by microarray showed 135-fold...
To better understand Euglena gracilis gene expression under different stress conditions (Chromium, Streptomycin or darkness), we undertook a survey of the E. gracilis transcriptome by cDNA sequencing and microarray analysis. First, we constructed a non-normalized cDNA library from the E. gracilis UTEX strain and sequenced a total of 1000 cDNAs. Six hundred and ten of these ESTs were similar to either...
Using a versatile and highly sensitive retroviral microarray, we have investigated particle preparations from three different human packaging cell lines harboring retroviral vector systems based on human immunodeficiency virus (HIV) and murine leukemia virus (MLV). 293Rev/Gag/Pol i cells inducibly express high titers of HIV-derived particles for packaging of HIV vectors. The Phoenix-GP and...
22q11 deletion syndrome (22q11DS) is a developmental anomaly caused by a microdeletion on human chromosome 22q11. Although mouse models indicate that Tbx1 is the gene responsible for the syndrome, the phenotypic spectrum of del22q11 patients is complex suggesting that gene–gene and gene–environment interactions are operative in delineating the pathogenesis of 22q11DS. In order to study the regulatory...
Microarray profiling of gene expression is a powerful tool for discovery, but the ability to manage and compare the resulting data can be problematic. Biological, experimental, and technical variations between studies of the same phenotype/phenomena create substantial differences in results. The application of conventional meta-analysis to raw microarray data is complicated by differences in the type...
