The vanilloid receptor-related TRP channels (TRPV1-6) mediate thermosensation, pain perception and epithelial Ca(2+) entry. As the specificity of TRPV channel heteromerization and determinants governing the assembly of TRPV subunits were largely elusive, we investigated the TRPV homo- and heteromultimerization. To analyze the assembly of TRPV subunits in(More)
We examined 219 Shiga toxin-producing Escherichia coli (STEC) strains from meat, milk, and cheese samples collected in Germany between 2005 and 2006. All strains were investigated for their serotypes and for genetic variants of Shiga toxins 1 and 2 (Stx1 and Stx2). stx(1) or variant genes were detected in 88 (40.2%) strains and stx(2) and variants in 177(More)
The TRPV4 cation channel exhibits a topology consisting of six predicted transmembrane domains (TM) with a putative pore loop between TM5 and TM6 and intracellular N- and C-tails, the former containing at least three ankyrin domains. Functional transient receptor potential (TRP) channels are supposed to result following the assembly of four subunits.(More)
A total of 140 Shiga toxin-producing Escherichia coli (STEC) strains from wildlife meat (deer, wild boar, and hare) isolated in Germany between 1998 and 2006 were characterized with respect to their serotypes and virulence markers associated with human pathogenicity. The strains grouped into 38 serotypes, but eight O groups (21, 146, 128, 113, 22, 88, 6,(More)
The cellular decoding of receptor-induced signaling is based in part on the spatiotemporal activation pattern of PKC isoforms. Because classical and novel PKC isoforms contain diacylglycerol (DAG)-binding C1 domains, they may compete for DAG binding. We reasoned that a Ca2+-induced membrane association of classical PKCs may accelerate the DAG binding and(More)
Functional characterizations of heterologously expressed TRPC4 have revealed diverse regulatory mechanisms and permeation properties. We aimed to clarify whether these differences result from different species and splice variants used for heterologous expression. Like the murine beta splice variant, rat and human TRPC4beta both formed receptor-regulated(More)
Although medulloblastoma (MB) represents the most frequent malignant brain tumour in children, the molecular pathogenesis of this tumour is still poorly understood. Microsatellite and RFLP studies have revealed allelic losses on the short arm of chromosome 17 in the region 17p13 in approximately 50% of MBs. A candidate for this putative MB suppressor on(More)
Endothelial progenitor cells (EPCs) may have an important role in vascular homeostasis and repair. We examined the level of circulating EPCs in pre- (n = 22; mean age 28.7 years), and postmenopausal healthy females without (n = 30; mean age 61.6 years) or under current hormone replacement therapy (HRT) (n = 19; mean age 59.8 years). Premenopausal females(More)
Most rod-shape model organisms such as Escherichia coli or Bacillus subtilis utilize two inhibitory systems for correct positioning of the cell division apparatus. While the nucleoid occlusion system acts in vicinity of the nucleoid, the Min system was thought to protect the cell poles from futile division leading to DNA-free miniature cells. The Min system(More)
