When isolated chromatin is incubated with the carcinogens N-methyl-N-nitrosourea (MeNU) and N-ethyl-N-nitrosourea (EtNU), DNA and chromosomal proteins become alkylated to increasingly greater extents as the carcinogen concentrations increase. With either MeNU or EtNU, the core and linker DNA of chromatin are alkylated to essentially identical extents. Alkylation of chromatin DNA as well as free DNA is drastically reduced at physiological ionic strengths (e.g. 0.15 M NaCl). The presence of 0.15 M NaCl, on the other hand, enhances alkylation of chromosomal proteins. While EtNU is much less reactive to DNA than MeNU, alkylation of chromosomal proteins relative to that of chromatin DNA has been found to be markedly greater with EtNU than with MeNU. Such a difference in their relative reactivities toward DNA and proteins may be related to the known difference of carcinogenic potency between these N-nitroso compounds.  相似文献

Owing to the complex nature of V1VO ATPases, identification of neighboring subunits is essential for mechanistic understanding of this enzyme. Here, we describe the links between the V1 headpiece and the VO-domain of the yeast V1VO ATPase via subunit A and d as well as the VO subunits a and d using surface plasmon resonance and fluorescence correlation spectroscopy. Binding constants of about 60 and 200 nM have been determined for the a-d and d-A assembly, respectively. The data are discussed in light of subunit a and d forming a peripheral stalk, connecting the catalytic A3B3 hexamer with VO.

Autism is a neurodevelopmental disorder characterized by impairments in social interaction, verbal communication and repetitive behaviors. BTBR mouse is currently used as a model for understanding mechanisms that may be responsible for the pathogenesis of autism. Growing evidence suggests that Ras/Raf/ERK1/2 signaling plays death-promoting apoptotic roles in neural cells. Recent studies showed a possible association between neural cell death and autism. In addition, two studies reported that a deletion of a locus on chromosome 16, which includes the MAPK3 gene that encodes ERK1, is associated with autism. We thus hypothesized that Ras/Raf/ERK1/2 signaling could be abnormally regulated in the brain of BTBR mice that models autism. In this study, we show that expression of Ras protein was significantly elevated in frontal cortex and cerebellum of BTBR mice as compared with B6 mice. The phosphorylations of A-Raf, B-Raf and C-Raf were all significantly increased in frontal cortex of BTBR mice. However, only C-Raf phosphorylation was increased in the cerebellum of BTBR mice. In addition, we further detected that the activities of both MEK1/2 and ERK1/2, which are the downstream kinases of Ras/Raf signaling, were significantly enhanced in the frontal cortex. We also detected that ERK1/2 is significantly over-expressed in frontal cortex of autistic subjects. Our results indicate that Ras/Raf/ERK1/2 signaling is upregulated in the frontal cortex of BTBR mice that model autism. These findings, together with the enhanced ERK1/2 expression in autistic frontal cortex, imply that Ras/Raf/ERK1/2 signaling activities could be increased in autistic brain and involved in the pathogenesis of autism.  相似文献

The fungus Synnematium jonesii was isolated from naturally infected adults of Promecotheca papuana and cultured in vitro. Caged beetles were successfully inoculated using an aqueous suspension of conidia and also a dust prepared from dried sclerotia. The implications of using this fungus for the control of P. papuana outbreaks is discussed.  相似文献

The genus Hebeloma has a number of species highly specific to Cistus and others that occur with several host genera. This paper discusses the species of Hebeloma that appear to be ectomycorrhizal with Cistus, judging from their occurrence when Cistus is the only available host. The previously unknown species H. plesiocistum spec. nov. is described. We also provide a key to the known Hebeloma associates of Cistus. Molecular analyses based on ITS sequence data further illustrate the distinctness of the newly described species and difficulties in the species delimitation with view to H. erumpens. Specific associations with Cistus may have evolved more than once within the genus Hebeloma.  相似文献

Data from microscopic morphology, single-spore cultures, and DNA analyses of teleomorphs and anamorphs support the recognition of five species of Prosthecium with Stegonsporium anamorphs on Acer: P. acerinum sp. nov., the teleomorph of S. acerinum; P. acerophilum comb. nov., formerly known as Dictyoporthe acerophila; P. galeatum comb. nov., originally described as Massaria galeata; P. opalus sp. nov.; and P. pyriforme sp. nov., the teleomorph of S. pyriforme s. str. The morphology of both type specimens and freshly collected material was investigated. The teleomorphs have brown ellipsoidal ascospores with five distosepta and often a longitudinal distoseptum. The anamorphs of all species described here belong to Stegonsporium; their connection to the Prosthecium teleomorphs was demonstrated by morphology and DNA sequences of single spore cultures derived from both ascospores and conidia. The anamorphs and teleomorphs of all five Prosthecium species are described and illustrated by LM images, and a key to these species is provided. As perceived from this work, S. pyriforme is restricted to Europe and does not occur in North America, whereas S. acerinum is restricted to North America, not found in Europe. The host associations given in the literature are revised and evidence is provided that only A. opalus, A. pseudoplatanus, and A. saccharum are confirmed hosts of Prosthecium with Stegonsporium anamorphs. Molecular phylogenetic analyses of tef1, ITS rDNA, and partial nuLSU rDNA sequences confirm that the species with Stegonsporium anamorphs are closely related to P. ellipsosporum, the generic type species. Stilbospora macrosperma is confirmed as the anamorph of P. ellipsosporum by DNA data of single spore isolates obtained from both ascospores and conidia.  相似文献

Association of Cdc42/N-WASP/Arp2/3 signaling pathway with Golgi membranes   总被引:1,自引:0,他引:1  
Recent findings indicate that Cdc42 regulates Golgi-to-ER (endoplasmic reticulum) protein transport through N-WASP and Arp2/3 (Luna et al. 2002, Mol. Biol. Cell, 13:866-879). To analyse the components of the Cdc42-governed signaling pathway in the secretory pathway, we localized Cdc42, N-WASP and Arp2/3 in the Golgi complex by cryoimmunoelectron microscopy. Cdc42 is found throughout the Golgi stack, particularly in cis/middle cisternae, whereas N-WASP and Arp3 (a component of the Arp2/3 complex) are restricted to cis cisternae. Arp3 also colocalized in peri-Golgi tubulovesicular structures with either KDEL receptor or GM130. Even though Arp3 is not found in TGN46-positive cisternal elements, a small fraction of Arp3-labeled tubulo-vesicular elements showed TGN46 labeling. Active Cdc42 (GTP-bound form) induced relocation of N-WASP and Arp3 to the lateral rims of Golgi cisternae. These results show that the actin nucleation and polymerization signaling pathway governed by Cdc42/N-WASP/Arp operates in the Golgi complex of mammalian cells, further implicating actin dynamics in Golgi-associated membrane trafficking.  相似文献

The ability of mebendazole and fenbendazole to bind to tubulin in cytosolic fractions from 8-day Ascaris suum embryos was determined by inhibition studies with [3H]colchicine. Colchicine binding in the presence of 1·10?6 M mebendazole was completely inhibited during a 6 h incubation period at 37°C. Inhibition of colchicine binding to A. suum embryonic tubulin by mebendazole and fenbendazole appeared to be noncompetative. The inhibition constants of mebendazole and fenbendazole for A. suum embryonic tubulin were 1.9·10?8 M and 6.5·10?8 M, respectively. Mebendazole and fenbendazole appeared to be competitive inhibitors of colchicine binding to bovine brain tubulin. The inhibition constants of mebendazole and fenbendazole for bovine brain tubulin were 7.3·10?6 M and 1.7·10?5 M, respectively. These values are 250–400 times greater than the inhibition constants of fenbendazole and mebendazole for A. suum embryonic tubulin. Differential binding affinities between nematode tubulin and mammalian tubulin for benzimidazoles may explain the selective toxicity. The importance of tubulin as a receptor for anthelmintic benzimidazoles in animal parasitic nematodes is discussed.  相似文献
