Influence Of A Cancer Inhibitor On A Single DNA Molecule Tracked (8/6/2007)

Researchers in Delft University of Technology's Kavli Institute of Nanoscience have cast new light on the workings of the important cancer inhibitor topotecan. Little had been known about the underlying molecular mechanism, but the Delft scientists can now view the effects of the medicine live at the level of a single DNA molecule. The research has been published online by the journal Nature on 24 June 2007. The lead author of the article, Daniel Koster, received his PhD at TU Delft on Monday 25 June 2007, partly on the results described in the article. ...> Full Article

Handicapping Tuberculosis May Be The Way To A Better Vaccine (8/6/2007)

Howard Hughes Medical Institute investigator William R. Jacobs and colleagues have produced a genetically altered strain of tuberculosis (TB) that elicits a stronger immune response than the current vaccine, bacillus Calmette-Guérin (BCG). The new vaccine improves survival of infected animals and may help put scientists on track to replace BCG, which has been used for nearly a century although it is largely ineffective. ...> Full Article

Diagnosing Obesity Prompts Action (8/5/2007)

Mayo Clinic physicians have identified that simply being diagnosed as obese increases a patient's likelihood of establishing a treatment plan with their physician, a crucial step in improving health. It's a significant finding, because obesity is a growing worldwide epidemic and the second leading cause of preventable death in developing countries. ...> Full Article

Immune Mechanism Could Explain Transient Immune Suppression in Acute Infections (8/5/2007)

Scientists have discovered that at the same time the immune system is vigorously attacking invading viruses or bacteria, it is unexpectedly reducing its production of a particular type of factor that directs the movement of immune cells. The new finding, which could help explain the transient immune suppression often seen during acute infections, shows that the immune system is even more complex than previously believed. ...> Full Article

Chromosomes Are Responsible For A Critical Enzyme's Activation During Cell Division (8/4/2007)

In a dividing cell, chromosomes interact with cellular scaffolding - called spindle microtubules - in order to move themselves to opposite ends of the cell, ensuring that both daughter cells receive an exact copy of their parent cell's genetic material. ...> Full Article

Cancer Stem Cells Created By Two Signalling Pathways (8/4/2007)

The linking of two signalling pathways in the cells of liver tumours has a clear influence on their malignancy. Activation of the platelet-derived growth factor (PDGF) messenger molecule is decisive for this linking. This results related to the development of liver cancer was generated during a current project by the Austrian Science Fund FWF and has been published in the Journal Oncogene. When the signalling pathways in liver tumour cells have been linked together, these cells develop the characteristics of cancer stem cells, which are in principal resistant to chemotherapy. This new understanding of the signalling pathways involved unlocks potential for the future development of modified therapies. ...> Full Article
