Meprin-α is a metalloprotease overexpressed in cancer cells, leading to the accumulation of this protease in a subset of colorectal tumors. The impact of increased meprin-α levels on tumor progression is not known. We investigated the effect of this protease on cell migration and angiogenesis in vitro and studied the expression of meprin-α mRNA, protein and(More)
Alternative oxidases (Aox or Aod) are present in the mitochondria of plants, fungi and many types of yeast. These enzymes transfer electrons from the ubiquinol pool directly to oxygen without contributing to the proton transfer across the mitochondrial membrane. Alternative oxidases are involved in stress responses, programmed cell death and maintenance of(More)
In this contribution, we present experimental results of our research on frequency-doubled semiconductor lasers emitting in the visible spectral range. These lasers include a laser-diode pumped semiconductor laser chip in an extended resonator configuration with a critically phase-matched lithium triborate crystal. The use of a single-plate Lyot filter(More)
