The objective of this article is to dissect the mechanisms by which the down-regulation of c-Myc induces programmed cell death in melanoma cells. In stable and doxycycline-inducible M14 melanoma cells, down-regulation of c-Myc induced apoptosis subsequent to a decrease in the intracellular reduced glutathione content and a concomitant accumulation of its oxidized form. This redox alteration was...
A potential cytosolic metallocarboxypeptidase from Burkholderia cenocepacia has been crystallized and a synchrotron-radiation microfocus beamline allowed the acquisition of diffraction data to 1.9 Å resolution. The asymmetric unit comprises a tetramer containing over 1500 amino acids, and the high-throughput automated protocols embedded in PDB_REDO were coupled with model-map inspections in ref...
The aim of the present in vitro study was to assess the tumoricidal potential of the following natural peptides belonging to the Cecropin family, namely Cecropin A and B, on a series of tumour cell lines: MDA-MB-231 (breast adenocarcinoma) and M14K (human mesothelioma). The experimental results reveal that the cytotoxic effects of the two peptides depend on their concentration. Their efficiency...
Complex interactions occur among host defense cells during bacterial infection. Bacteria and bacterial products may enhance or inhibit the effector and regulatory activity of human lymphocytes. Accordingly, we tested the ability of human periodontal pathogens to activate peripheral blood lymphocytes using standard chromium-release assays to measure lymphocyte-mediated cytolysis. Human adherent-...

Our tests reveal that verbal is significantly associated with both analyst asking question and CEO fielding question. First, we find male analysts are more verbally aggressive than female analysts. Specifically, direct likely to be followed further questions, have a prefa...
