Compound from marine bacteria shows potential as multiple myeloma therapy

...umor cells, NPI-0052 was well tolerated, prolonged survival and significantly reduced the rate of cancer recurrences. Because NPI-0052 and bortezomib block the proteasome in different ways, the researchers tested them together on myeloma cells. They found that the cancer cells were killed more effectively by ...

Brainstem blocks pain to protect key behaviors

... eating, drinking and urinating, are so crucial to survival that the brains of all vertebrates contain clusters of nerve cells that can suppress pain long enough to allow the animal to eat, drink -- or pee -- in peace. A report from researchers at the University of Chicago, published early online in the Pr...

Harnessing genomic research

...nvestigating the microbial genes important for the survival and growth of the salmonella pathogen during infection is using this knowledge to generate mutant bacterial strains that may be useful as vaccines. Experiments under way have shown several mutant bacterial strains to be highly effective as vaccines. ...

Many breast cancer cells require estrogen for survival (called estrogen receptor–positive breast cancers), and apoptosis of such cells can be induced with treatments that block estrogen, such as tamoxifen, fulvestrant, or aromatase inhibitors. Paradoxically, some cells can become adapted to survive when ...
