Kinase suppressors of Ras 1 and 2 (KSR1 and KSR2) function as molecular scaffolds to potently regulate the MAP kinases ERK1/2 and affect multiple cell fates. Here we show that KSR2 interacts with and modulates the activity of AMPK. KSR2 regulates AMPK-dependent glucose uptake and fatty acid oxidation in mouse embryonic fibroblasts and glycolysis in a(More)
Among all metazoan phyla, sponges are known to produce the largest number of bioactive compounds. However, until now, only one compound, arabinofuranosyladenine, has been approved for application in humans. One major obstacle is the limited availability of larger quantities of defined sponge starting material. Recently, we introduced the in vitro culture of(More)
The past decade has witnessed a dramatic increase in studies of amphibian and reptile specific dynamic action (SDA). These studies have demonstrated that SDA, the summed energy expended on meal digestion and assimilation, is affected significantly by meal size, meal type, and body size and to some extent by body temperature. While much of this attention has(More)
A new multipurpose cell micro-assay has been developed, using the protein dye amido black 10B as an indicator of cell numbers in 96-well plates. The assay is reliable, rapidly performed and can be combined with morphological evaluation and photography of stained cells. It permits investigations of various cell types including the human keratinocyte line(More)
Our recent data suggest that during auto- and allograft recognition in sponges (Porifera), cytokines are differentially expressed. Since the mitogen-activated protein kinase (MAPK) signal transduction modulates the synthesis and release of cytokines, we intended to identify one key molecule of this pathway. Therefore, a cDNA from the marine sponge Suberites(More)
Inflammatory bone diseases are characterized by the presence of pro-inflammatory cytokines that regulate bone turnover. Osteoprotegerin (OPG) is a soluble osteoblast-derived protein that influences bone resorption by inhibiting osteoclast differentiation and activation. In the present study, we demonstrate that interleukin-1beta and tumor necrosis factor(More)
Alzheimer's disease, a major form of dementia in the elderly has become an increasingly important health problem in developed countries. In vitro studies on primary neurons demonstrate that Flupirtine (Katadolon) at a concentration of 1 microg/ml, significantly reduces the neurotoxic (apoptotic) effect displayed by A beta25-35, a segment of the amyloid(More)
Only few investigators still report in literature that estradiol type I receptors can be histochemically visualized using estradiol-albumin-FITC conjugates (E2-BSA-FITC). Most of them report that it is not likely that fluorescence is due to conjugate--type I receptor interaction. It is assumed that rather type II receptors are involved. In this study clear(More)
The public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information.
