With the goal of identifying genes that have an expression pattern that can facilitate the diagnosis of primary breast cancers (BCs) as well as the discovery of novel drug leads for BC treatment, we used cDNA hybridization arrays to analyze the gene expression profiles (GEPs) of nine weakly invasive and four highly invasive BC cell lines. Differences in(More)
We have identified a 2.6-kb mRNA whose steady state levels are increased 2- to 4-fold by treatment of human mammary epithelial cells (HMEC) stably expressing an estrogen receptor (ER) transgene with either estrogen (E) or the antiestrogen, 4-hydroxy-tamoxifen (HT). The cDNA corresponding to this mRNA encodes a 564-amino acid protein, named(More)
Clinical studies have shown that estrogen replacement therapy (ERT) reduces the incidence and severity of osteoporosis and cardiovascular disease in postmenopausal women. However, long term estrogen treatment also increases the risk of endometrial and breast cancer. The selective estrogen receptor (ER) modulators (SERMs) tamoxifen and raloxifene, cause(More)
We describe the chimerization of a monoclonal antibody directed against the c-erbB-2 protein using a novel PCR method for cloning immunoglobulin variable region genes. We also describe the characterization of the chimera and show its potential use for treating cancers which overexpress the c-erbB-2 protein. The genomic DNA fragments of heavy and light chain(More)
Human granulosa tumor cell (GCT) lines (KGN and COV434) were utilized to establish the combinatorial effects of TRAIL treatment and a proteasome inhibitor on cell viability, in vitro. TRAIL induced a slight, but consistent, decrease in viability for both cell lines, and pharmacologic inhibition of proteasome activity, using Z-LLF-CHO (Z-LLF),(More)
Three proteins (env, gag, and tax) encoded by the human T-cell leukemia virus type I (HTLV-I) genome were cloned and expressed in Escherichia coli. The env protein contained a substantial part of the gp46 domain and a majority of the p21e domain. The gag protein contained all of p24 and portions of p19 and p15. In addition to these two structural proteins,(More)
These studies were performed to determine whether the erythrocytes (RBC's) of chickens are able to alter the concentrations of organic phosphates, particularly inositol pentakis (dihydrogen phosphate) (inositol-P5), in response to anemia. Acute anemia with 33.5% reticulocytes (retics) in the peripheral blood of 4-month-old White Leghorn cockerels was(More)
Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) represents one of several cytokine members of the tumor necrosis factor superfamily reported to initiate apoptosis in a wide range of transformed, but not most normal, cell types. The present studies were conducted to evaluate the potential for TRAIL to promote apoptotic cell death in(More)
The nucleotide sequence from the 5' terminus to nucleotide 3822 has been determined for the genome of the enterovirus, coxsackievirus B3 (CB3). This region encompasses the 5'-terminal 738 nucleotide non-coding sequence and the region which codes for the four viral capsid proteins and for the initial products of the P2 region. Regions in the 5'(More)
The B30.2-like domain occurs in some members of a diverse and growing family of proteins containing zinc-binding B-box motifs, whose functions include regulation of cell growth and differentiation. The B30.2-like domain is also found in proteins without the zinc-binding motifs, such as butyrophilin (a transmembrane glycoprotein) and stonustoxin (a secreted(More)
