Taking out the Protein Garbage Becomes More Difficult as Neurons Age

Perelman School of Medicine at the University of Pennsylvania

As cells age, their ability to shed harmful refuse declines. New research findings suggest that the deterioration of autophagy in aged neurons—cells that never replicate and are as old as the bodies they inhabit—could be a risk factor for a suite of neurodegenerative diseases such as ALS (amyotrophic lateral sclerosis), Alzheimer’s, and Parkinson’s.

Crunching the Numbers of Cancer Metastasis

Beth Israel Deaconess Medical Center

In a study published in Scientific Reports, first author Yamicia D. Connor, MD, PhD, a resident in the Department of Obstetrics and Gynecology at Beth Israel Deaconess Medical Center (BIDMC), and colleagues, reveal that unlike non-metastatic cells, breast metastatic cells have the ability to change shape, flattening to more effectively cross the endothelium and into the blood stream.
