Various plant extracts, such as carrot, burdock (gobou), apricot and prune, showed inhibitory effects in an in vitro assay of lipid peroxide-induced 8-hydroxydeoxyguanosine (8-OH-dG) formation. The major inhibitor purified from various plants extract

The ras oncogene-encoded p21 protein is known to induce cell maturation of Xenopus laevis oocytes and malignant transformation of NIH 3T3 mouse fibroblasts. The pathways involved in oocytes and NIH 3T3 cells appear to be similar to one another. For e

Minor leucine tRNA species, tRNA(Leu)4 and tRNA(Leu)5, from Escherichia coli B have been reported to recognize leucine codons UUA and UUG [Goldman, E., Holmes, W. M., and Hatfield, G. W. (1979) J. Mol. Biol. 129, 567-585]. In the present study, these

2-amino-1-methyl-6-(4-hydroxyphenyl)imidazo[4,5-b]pyridine (4'-OH-PhIP) was mutagenic, inducing 180 revertants of Salmonella typhimurium TA98 per 100 micrograms with S9 mix and was formed by heating a mixture of creatine, tyrosine and glucose. It was

The small-angle X-ray scattering technique was used to characterize the structure in solution of wild type ras p21 as well as the oncogenic proteins mutated at residue 12, 59, or 61. In the presence of GDP, the radius of gyration, Rg, determined for

A nickel-binding serine proteinase inhibitor, pNiXa (43 kDa), was isolated from Xenopus ovary and assayed for effects on oocyte maturation. Microinjection of pNiXa (0.12 pmol/50 nl) induced maturation in 60% of Xenopus oocytes, beginning at 4 hours a

The ras-oncogene-encoded p21 protein is known to cause a large number of human tumors. This protein differs from its normal counterpart protein, which is present in all eukaryotic cells, in that it contains a single amino acid substitution at critica

RAS genes isolated from human tumors often have mutations at positions corresponding to amino acid 12 or 61 of the encoded protein (p21), while retroviral ras-encoded p21 contains substitutions at both positions 12 and 59. These mutant proteins are d

Potosensitized formation of 8-hydroxyguanine in DNA by riboflavin was observed. A reaction mechanism involving guanine radical cation and hydration reaction was proposed. This hypothesis was confirmed by the incorporation of [18O]-atom within guanine

The ras-oncogene-encoded p21 protein causes malignant transformation of NIH 3T3 cells and maturation of Xenopus oocytes when microinjected into these cells. P21 is known to interact with GTPase activating protein (GAP) intracellularly. Residues 32-45
