RelB-deficient mice (relB(-/-)) have a complex phenotype including multiorgan inflammation and hematopoietic abnormalities. To examine whether other NF-kappaB/Rel family members are required for the development of this phenotype or have a compensatory role, we have initiated a program to generate double-mutant mice that are deficient in more than one family(More)
RelB, a member of the NF-kappa B/Rel family of transcription factors, has been implicated in the constitutive expression of kappa B-regulated genes in lymphoid tissues. We have generated mice carrying a germline mutation of the relB gene, resulting in the absence of RelB protein and a dramatic reduction of constitutive kappa B-binding activity in thymus and(More)
The nfkb2 gene is a member of the Rel/NF-kappa B family of transcription factors. COOH-terminal deletions and rearrangements of this gene have been associated with the development of human cutaneous T cell lymphomas, chronic lymphocytic leukemias, and multiple myelomas. To further investigate the function of NF-kappa B2, we have generated mutant mice(More)
Nitric oxide is a short-lived cytotoxic mediator that has been implicated in the pathogenesis of endotoxin-induced tissue injury and septic shock. In the present studies we determined whether this mediator is produced in the lung during acute endotoxemia. We found that intravenous injection of rats with bacterially derived lipopolysaccharide (LPS), a(More)
Binary quantitative structure-activity relationship (QSAR) models are developed to classify a data set of 334 aromatic and secondary amine compounds as genotoxic or nongenotoxic based on information calculated solely from chemical structure. Genotoxic endpoints for each compound were determined using the SOS Chromotest in both the presence and absence of an(More)
The insulin response element (IRE) of the human insulin-like growth factor-binding protein-1 (IGFBP-1) promoter contains a palindrome of the T(A/G)TTT sequence crucial to hormonal regulation of many genes. In initial studies of how this IRE participates in hormonal regulation, the electromobility shift assay was used under a variety of conditions to(More)
Previous studies suggest that growth retardation in children with chronic renal failure (CRF) results in part from inhibition of insulin-like growth factor (IGF) action by excess serum IGF-binding proteins (IGFBPs). Excess IGFBPs in CRF serum include IGFBP-1, -2, and -3 and a diffuse approximately 24- to 28-kDa IGFBP band identified by [125I]IGF ligand(More)
During extrauterine life, insulin-like growth factors (IGFs) circulate in a ternary serum complex with one IGF-binding protein-3 (IGFBP-3) or IGFBP-5 protein and with a single acid-labile subunit (ALS). GH increases levels of this ternary complex; in mice, this effect is achieved in part by the ability of GH to stimulate mouse ALS (mALS) transcription(More)
The effects of high toxic doses of the anticancer drugs, etoposide and its phosphate derivative, BMY-40481, on the nervous system of female CD-1 mice were examined by light microscopy (LM) and transmission electron microscopy. Mice were euthanatized 4 wk following a single iv injection of either 0, 50, 100, or 150 mg/kg of BMY-40481 or 44 or 88 mg/kg of(More)
