Nitric oxide synthesis contributes to IL-2-induced antitumor responses against intraperitoneal Meth A tumor

Autor: C Y, Yim, J R, McGregor, O D, Kwon, N R, Bastian, M, Rees, M, Mori, J B, Hibbs, W E, Samlowski

Publikováno v: Journal of immunology (Baltimore, Md. : 1950). 155(9)

IL-2 therapy is a potent inductive stimulus for nitric oxide (NO.) synthesis in mice and humans. It is not yet clear whether NO. can contribute to IL-2-induced therapeutic responses. The murine skin cancer Meth A is relatively resistant to lymphokine

Nitric oxide stabilizes the Mo(V) oxidation state of dimethyl sulfoxide reductase from Rhodobacter sphaeroides without inhibiting enzyme activity

Autor: N R, Bastian, M J, Foster, J C, Pope

Publikováno v: BioFactors (Oxford, England). 5(1)

Dimethyl sulfoxide reductase from Rhodobacter sphaeroides is isolated in an oxidized, Mo(VI) containing form. Both nitric oxide and reduced ascorbate carried out a one electron reduction of the enzyme with formation of stoichiometric amounts of EPR a

Induction of iron-derived EPR signals in murine cancers by nitric oxide. Evidence for multiple intracellular targets

Autor: N R, Bastian, C Y, Yim, J B, Hibbs, W E, Samlowski

Publikováno v: The Journal of biological chemistry. 269(7)

The cell-mediated immune response to syngeneic tumors activates the cytokine-inducible nitric oxide synthase. We observed that syngeneic murine tumors exhibited EPR signals related to iron-nitrosyl complex formation. Three different EPR active iron-n

Macrophage nitric oxide synthesis delays progression of ultraviolet light-induced murine skin cancers

Autor: C Y, Yim, N R, Bastian, J C, Smith, J B, Hibbs, W E, Samlowski

Publikováno v: Cancer research. 53(22)

The role of macrophages in the host immune response against cancers remains uncertain. Since nitric oxide synthesis represents a significant macrophage antitumor mechanism in vitro, we evaluated whether NO was synthesized during the immune response t

31P-NMR of free and protein-bound molybdopterin guanine dinucleotide

Autor: N R, Bastian, J L, Johnson, K V, Rajagopalan

Publikováno v: BioFactors (Oxford, England). 3(3)

Molybdopterin guanine dinucleotide was studied by 31P-NMR in the free, iodoacetamide derivatized form [di(carboxamidomethyl)molybdopterin] and in the native state in the dimethyl sulfoxide reductase from Rhodobacter sphaeroides. The spectra confirm t

Identification of molybdopterin guanine dinucleotide in formate dehydrogenase from Methanobacterium formicicum

Autor: J L, Johnson, N R, Bastian, N L, Schauer, J G, Ferry, K V, Rajagopalan

Publikováno v: FEMS microbiology letters. 61(2-3)

The pterin cofactor in formate dehydrogenase isolated from Methanobacterium formicium is identified as molybdopterin guanine dinucleotide. The pterin, stabilized as the alkylated, dicarboxamidomethyl derivative, is shown to have absorption and chroma

Spectroscopic studies of the molybdenum-containing dimethyl sulfoxide reductase from Rhodobacter sphaeroides f. sp. denitrificans

Autor: N R, Bastian, C J, Kay, M J, Barber, K V, Rajagopalan

Publikováno v: The Journal of biological chemistry. 266(1)

Absorption and EPR spectroscopic properties of purified dimethyl sulfoxide (Me2SO) reductase from Rhodobacter sphaeroides f. sp. denitrificans have been examined. The absence of prosthetic groups other than the molybdenum center in the enzyme has mad
