The eubacterial species Streptomyces coelicolor proceeds through a complex growth cycle in which morphological differentiation/development is associated with a transition from primary to secondary metabolism and the production of antibiotics. We used DNA microarrays and mutational analysis to investigate the expression of individual genes and multigene(More)
Using the Escherichia coli lacZ gene to identify chromosomal loci that are transcriptionally active during growth arrest of NIH 3T3 fibroblasts, we found that an mRNA expressed preferentially in serum-deprived cells specifies the previously characterized alpha-receptor (alphaR) for platelet-derived growth factor (PDGF), which mediates mitogenic(More)
Antisense inactivation of the tsg101 tumor susceptibility gene in murine NIH3T3 fibroblasts leads to neoplastic transformation and tumorigenesis, which are reversed by restoration of tsg101 activity. tsg101 deficiency is associated with a series of mitosis-related abnormalities, whereas overexpression of TSG101 can also result in neoplastic transformation(More)
We have isolated and sequenced a Drosophila genomic DNA that encodes the entire coding region of the laminin B1 chain. The genomic DNA sequenced spans 11,787 bp, including a 1.1-kb 5'-flanking region, 5 exons, 4 introns, and a 1.4-kb 3'-flanking region. The open reading frame is within the two largest exons, the exons 3 and 4, while the first two and the(More)
We report here the design, construction and testing of a self-inactivating (Sin) retrovirus promoter-trap vector suitable for identifying and isolating transcriptionally active regions from the mouse genome. When this vector, which contains the bacterial aph gene as its reporter, is integrated into a site downstream from an active host cell promoter, it(More)
