To test our hypothesis that substitution of domain III of Bacillus thuringiensis delta-endotoxin (Cry) proteins might improve toxicity to pest insects, e.g., Spodoptera exigua, in vivo recombination was used to produce a number of cryIA(b)-cryIC hybrid genes. A rapid screening assay was subsequently exploited to select hybrid genes encoding soluble(More)
In enterobacteria such as Salmonella, flagellar biogenesis is dependent upon the master operon flhDC at the apex of the flagellar gene hierarchy, which is divided into three classes 1, 2 and 3. Previously we reported that depletion of the ClpXP ATP-dependent protease results in dramatic enhancement of class 2 and class 3 gene transcription, whereas the(More)
Emerging evidence suggests the involvement of programmed cell death and inflammation in amyotrophic lateral sclerosis (ALS). To assess molecular pathological effects of the anti-inflammatory peroxisome proliferator-activated receptor-gamma (PPARgamma) agonist pioglitazone in ALS, we verified changes in the population of neurons, astrocytes, and microglia in(More)
Hypoglycosylation of alpha-dystroglycan (alpha-DG) has been identified in several human diseases associated with muscular dystrophy and brain malformations, including Fukuyama-type congenital muscular dystrophy (FCMD) caused by mutations in the fukutin gene. Although disruption of the intra-extra membrane linkage in the sarcolemma via the dystroglycan (DG)(More)
BACKGROUND Emerging evidence suggests that innate immunity and increased oxidative stress contribute to pathomechanisms in amyotrophic lateral sclerosis (ALS). The aim of the present study was to verify the involvement of monocyte chemoattractant protein-1 (MCP-1) and its specific CC chemokine receptor 2 (CCR2) in the disease progression of ALS. We here(More)
BACKGROUND Epithelioid trophoblastic tumor (ETT) is a rare entity within trophoblastic tumors. It is difficult to recognize ETT because of its epithelioid appearance. CASE A 35-year-old female, 5 years after pregnancy, experienced genital bleeding 2 months prior to consulting us. Preoperative laboratory data showed a slightly elevated serum level of human(More)
A novel cryIC-type gene was isolated from a strain of Bacillus thuringiensis subsp. galleriae. A new polymerase chain reaction (PCR) technique with a set of several oligonucleotide primer pairs specific to the cryIC gene was used to screen a number of B. thuringiensis strains. PCR amplified several DNA fragments ranging from 100 bp to 1 kb for B.(More)
Sulfated glycosaminoglycans (GAGs), including heparan sulfate and chondroitin sulfate, are synthesized on the so-called common GAG-protein linkage region (GlcUAbeta1-3Galbeta1-3Galbeta1-4Xylbeta1-O-Ser) of core proteins, which is formed by the stepwise addition of monosaccharide residues by the respective specific glycosyltransferases.(More)
Salmonella enterica serovar Typhimurium, similar to various facultative intracellular pathogens, has been shown to respond to the hostile conditions inside macrophages of the host organism by inducing stress proteins, such as DnaK. DnaK forms a chaperone machinery with the cochaperones DnaJ and GrpE. To elucidate the role of the DnaK chaperone machinery in(More)
An early step in the pathogenesis of Salmonella enterica serovar Typhimurium infection is bacterial penetration of the intestinal epithelium. Penetration requires the expression of invasion genes found in Salmonella pathogenicity island 1 (SPI1). These genes are controlled in a complex manner by regulators in SPI1, including HilA and InvF, and those outside(More)
