Researchers may have found test for depression

Researchers from the University of Illinois at Chicago College of Medicine have discovered that a change in the location of a protein in the brain could serve as a biomarker for depression, allowing a simple, rapid, laboratory test to identify patients with depression and to determine whether a particular antidepressant therapy will provide a successful response.

Structure reveals how cells 'sugar-coat' proteins - process essential to many proteins' functions can lead to disease when gone awry

Biologists at the U.S. Department of Energy's Brookhaven National Laboratory, Stony Brook University, and the University of Wurzburg, Germany, have deciphered the structure of a large protein complex responsible for adding sugar molecules to newly formed proteins - a process essential to many proteins' functions.

Flat, non-polypoid colorectal neoplasms linked to colorectal cancer

Flat, non-polypoid colorectal neoplasms (NP-CRNs), which may be difficult to detect, appear to be relatively common and may have a greater association with cancer compared with the more routinely diagnosed type of colorectal polyps, according to a study in the March 5 issue of JAMA.

New discovery on programmed cell death

Investigators at St. Jude Children's Research Hospital have discovered a dance of proteins that protects certain cells from undergoing apoptosis, also known as programmed cell death. Understanding the fine points of apoptosis is important to researchers seeking ways to control this process.
