A herpes simplex virus mutant, in1814, possessing a 12-base-pair insertion in the gene encoding the transinducing factor Vmw65 has been constructed. The insertion abolished the ability of Vmw65 to transinduce immediate-early (IE) gene expression and to form a protein-DNA complex with cell proteins and the IE-specific regulatory element TAATGAGAT.(More)
Passage of human immunodeficiency virus type 1 in the presence of increasing 2'-deoxy-3'-thiacytidine (3TC) concentrations results in high-level (> 100-fold) 3TC-resistant viruses. All 3TC-resistant viruses possess a substitution at the second codon (from a methionine into an isoleucine) at position 184 within the highly conserved motif (YMDD) of human(More)
Dystroglycans are essential transmembrane adhesion receptors for laminin. Alpha-dystroglycan is a highly glycosylated extracellular protein that interacts with laminin in the extracellular matrix and the transmembrane region of beta-dystroglycan. Beta-dystroglycan, via its cytoplasmic tail, interacts with dystrophin and utrophin and also with the actin(More)
The in-vitro susceptibilities of two strains of feline immunodeficiency virus to 18 antiviral agents were determined in two cell lines. In terms of inhibiting p24 antigen production, the nucleoside-analogue reverse transcriptase inhibitors were the most effective compounds. Inhibition was also observed with aurintricarboxylic acid, phosphonoformate and(More)
The two isoforms of carnitine palmitoyltransferase I (CPT I; muscle (M)- and liver (L)-type) of the mitochondrial outer membrane have distinct kinetic characteristics with respect to their affinity for one of the substrates (l-carnitine) and the inhibitor malonyl-CoA. Moreover, they differ markedly in their hysteretic behavior with respect to malonyl-CoA(More)
In this paper we describe the in vitro antiviral activity of the (-) enantiomer of carbocyclic 2',3'-deoxydidehydroguanosine, (-) carbovir, a nucleoside analogue that has selective and potent anti-HIV activity in a series of lymphocyte culture systems. The cellular cytotoxicity of this compound has also been evaluated in a number of systems and compared to(More)
The role of the herpes simplex virus (HSV)-encoded ribonucleotide reductase (RR) in the pathogenicity of the virus has been examined by use of mutants with lesions in either the large or small subunit of the enzyme. The virulence of the mutants in mice was reduced by about 10(6)-fold when compared with that of the parental virus (HSV type 1 strain 17),(More)
