A set of 1091 human skeletal muscle cDNA clone inserts representing more than 800 human gene transcripts were spotted as PCR products at high density on nylon membranes. Replicas of the filters were hybridized in stringent conditions with 33P-radiolabeled cDNA probes transcribed from skeletal muscle poly(A)+ RNA. Hybridization signals were collected on… (More)
Detailed analysis of a set of 18,698 sequences derived from both ends of 10,979 human skeletal muscle and brain cDNA clones defined 6676 functional families, characterized by their sequence signatures over 5750 distinct human gene transcripts. About half of these genes have been assigned to specific chromosomes utilizing 2733 eSTS markers, the polymerase… (More)
Innate immunity is the major host defense against invasive aspergillosis. To determine whether the collectin mannan-binding lectin (MBL) is involved in the initial protective immunity through complement activation against opportunistic fungal infections caused by Aspergillus, we performed in vitro studies on 29 different strains of Aspergillus conidia from… (More)
We show by cloning and nucleotide sequence analysis that the 18kDa antigen found in the urine of patients suffering from aspergillosis is related to the fungal protein toxins restrictocin and mitogillin. These are inhibitors of translation which act by catalytic inactivation of eukaryotic ribosomes; they may be implicated in the pathogenesis of the disease.
The aspfI gene encoding a ribonucleotoxin, a putative virulence factor of Aspergillus fumigatus, was inactivated by gene disruption. Gene replacement through homologous recombination by the disrupted allele tagged by the hygromycin B resistance marker was performed by transformation of a pathogenic strain. One transformant with the disrupted aspfI gene… (More)
We describe the cloning and characterization of the gene coding for the ribotoxin restrictocin, from Aspergillus restrictus (gene res, EMBL accession Number X56176). This toxin is a potent inhibitor of protein synthesis in eucaryotes and is of potential interest as a component of immunotoxins. To analyze the mechanism of self-protection in the producing… (More)
We have developed an integrated approach for the analysis of human cDNA libraries from neuromuscular tissues, based on the acquisition of primary structural, expression and mapping data. 26,938 sequence signatures (over 7 million bases) have been derived from both ends of skeletal muscle and brain cDNA clones. Primary redundancy analysis and classification… (More)
