A lipolytic enzyme gene (lip8) was cloned from organic solvent-tolerant Pseudomonas aeruginosa LST-03 and sequenced. In the sequenced nucleotides, an open reading frame consisting of 1,173 nucleotides and encoding 391 amino acids was found. Lip8 is considered to belong to the family VIII of lipolytic enzymes whose serine in the consensus sequence of(More)
We have identified human prostate cancer- and tissue-specific genes using cDNA library subtraction in conjunction with high throughput microarray screening. Subtracted cDNA libraries of prostate tumors and normal prostate tissue were generated. Characterization of subtracted libraries showed enrichment of both cancer- and tissue-specific genes. Highly(More)
Previously we reported that ischemia results in apoptosis and is accompanied by phosphorylation on Tyr-701 and increased expression and transcriptional activity of the signal transducer and activator of transcription-1 (STAT-1). In the present study, we show that exposure of cardiomyocytes to ischemia induced the phosphorylation of STAT-1 at another site,(More)
We previously found that the level of Fas, a cell surface receptor for an apoptosis signal, increases at the mRNA level in influenza virus-infected HeLa cells prior to their death by apoptosis. Here we investigated the mechanism of activation of the Fas-encoding gene expression upon influenza virus infection. Nucleotide sequences for the binding of nuclear(More)
Both monomeric and dimeric constructs of the B domain of protein A from Staphylococcus aureus have been characterized by NMR, CD and fluorescence spectroscopy. The monomeric form of the protein was synthesized using a novel method incorporating the use of a recombinant, folded, chimeric protein. A comparison of the recombinant monomeric form with the(More)
We have characterized the genomic structure and expression of the mouse gene for Pur-1. The cloned Pur-1 gene spans a 5-kb region encompassing the promoter, five exons, four introns and the 3'-untranslated region. All exon-intron junction sequences conform to the GT/AG rule. The promoter region has typical features of a housekeeping gene: a high G + C(More)
"Regulation of the Expression of the PCNA Gene." Renato Baserga, Hansjuerg Alder, Ren~e-H~l~ne Charollais, and Zbignlew Pietrzkowski, Jefferson Cancer Institute, Thomas Jefferson University, Bluemle Life Sciences Building, 233 S. lOth Street, Philadelphia, PA, USA. The PCNAmRNA levels are growth-regulated. A number of investigators, from this and other(More)
We have cloned and characterized the genomic structure of the human gene for Myc-associated zinc finger protein (MAZ), which is located on chromosome 16p11.2. This gene is transcribed as an mRNA of 2.7 kilobases (kb) that encodes a 60-kDa MAZ protein. A 40-kb cosmid clone was isolated that includes the promoter, five exons, four introns, and one(More)
KNSL4 (Kid; kinesin-like DNA-binding protein) is a member of the kinesin family that is involved in spindle formation and the movements of chromosomes during mitosis and meiosis. Myc-associated zinc finger protein (MAZ) participates in both the initiation and the termination of transcription of target genes. We isolated genomic DNA clones that encoded KNSL4(More)
Gene therapy based on gene-specific nucleic acids has moved from theory to a practical possibility in a very short time. The new DNA and RNA therapeutic reagents are intended to stop the growth of cancerous cells or the production of viruses. At the practical level, the efficacy of antisense oligomers as therapeutic reagents has been carefully examined in(More)
