View SamplesUremic media calcification is not only driven by systemic factors such as hyperphosphatemia, but also crticially dependent on vascular smooth muscle cells per se. We hypothesized that the different developmental origins of vscular smooth muscle cells might lead to a heterogeneous susceptibility to develop media calcification.

View SamplesAZD1208 is a novel PIM kinase inhibitor that we have shown inhibits tumorigenesis in tissue recombination models, Myc-CaP allograft models, and human prostate cancer xenografts. We sought to determine the intracellular pathways that are responsible for the anti-tumor effect. To this end we used the tissue recombination protocol to implant MYCCaP cells into castrated mice. MYCCaP cells are an androgen-dependent mouse cell line that overexpresses the oncogene MYC. The mice used for implantation were castrated, so any tumors that result from the grafting procedure are androgen-independent. The grafted mice were divided into a control population receiving vehicle, and a test population receiving AZD1208. The tumors were harvested and in vitro cell lines were made. The new cell lines have been perpetuated in androgen-depleted media.

View SamplesThe alarmins myeloid-related protein (MRP) 8 and MRP14 are the dominant cytoplasmic proteins in phagocytes. After release by activated phagocytes extracellular MRP8/MRP14 complexes promote inflammation in many diseases, including infections, allergies, autoimmune diseases, rheumatoid arthritis or inflammatory bowel disease. As receptors for the pro-inflammatory effects of human MRP8, the active component of the MRP8/MRP14-complex, Toll-like receptor (TLR) 4 and the multi-ligand receptor of advanced glycation end products (RAGE) are controversial discussed. Using a comparative bioinformatics analysis between genome-wide response patterns of monocytes to MRP8, endotoxin and different cytokines we demonstrated a dominant role of TLR4 during MRP8-mediated phagocyte activation. The relevance of this signaling pathway could be confirmed in independent cell models for TLR4 and RAGE dependent signaling in mouse and man. In addition to well-known proinflammatory functions of MRP8 our systems biology approach unraveled a novel anti-apoptotic effect of MRP8 on monocytes which was confirmed in independent functional experiments. Our data define the dominance of the TLR4-MRP8 axis in activation of human phagocytes which represents a novel attractive target for modulation of overwhelming innate immune responses.
