Scientists Use Nanoparticles to Shut Down Mechanism that Drives Cancer Growth

July 7, 2015 9:50 am | by UCLA | News | Comments

When scientists develop cancer therapies, they target the features that make the disease deadly: tumor growth, metastasis, recurrence and drug resistance. In epithelial cancers — cancers of the breast, ovaries, prostate, skin and bladder, which begin in the organs’ lining — these processes are controlled by a genetic program called epithelial–mesenchymal transition.

July 2, 2015 11:07 am | by Lauran Neergaard, Associated Press | News | Comments

One vaccine used in Europe during the 2009 swine flu pandemic was linked to rare cases of a baffling side effect - the sleep disorder narcolepsy. Now new research offers a clue to what happened.

Too Exhausted to Fight – and to Do Harm

July 2, 2015 10:58 am | by University of Cambridge | News | Comments

An ‘exhausted’ army of immune cells may not be able to fight off infection, but if its soldiers fight too hard they risk damaging the very body they are meant to be protecting, suggests new research.

Rearming Immune Cells Blasts Ovarian Cancer in Mice

July 2, 2015 9:47 am | by Cynthia Fox, Science Writer | Articles | Comments

One reason ovarian cancer is so deadly: it turns off immune cells that try to fight it. A Weill Cornell Medical College team has found that disarming a gene called XBP1 rearms immune cells—which successfully combat ovarian cancer.

Failure of Cells’ ‘Garbage Disposal’ System May Contribute to Alzheimer’s

July 1, 2015 12:54 pm | by Yale University | News | Comments

Lysosomes, the “garbage disposal” systems of cells, are found in great abundance near the amyloid plaques in the brain that are a hallmark of Alzheimer’s disease. Scientists have long assumed that their presence was helpful — that they were degrading the toxic proteins that trigger amyloid plaque formation.
