Nanoparticle-enabled peptide delivery triggers tumor regression

Cells possess a variety of ways of dealing with mutations that can cause them to grow uncontrollably and eventually form a tumor. The tumor suppressor gene p53 plays a critical role in these cancer prevention processes, largely by triggering a form a cell death known as apoptosis.

What makes people susceptible to rheumatoid arthritis?

Peter K. Gregersen, MD, stares at x-rays of hands, searching out the telltale signs of inflamed joints and wrists from his research subjects with rheumatoid arthritis. With these clinical features at his side, he turns to the basic building blocks of life , the human genome , to figure out what makes these people susceptible to the disabling inflammatory condition.

Gamma-secretase acts as a tumor suppressor

Researchers at Burnham Institute for Medical Research (Burnham) have provided the first evidence that gamma-secretase, an enzyme key to the progression of Alzheimer's, acts as a tumor suppressor by altering the pathway of epidermal growth factor receptor (EGFR), a potential treatment target for cancer.
