Tenfold boost in ability to pinpoint proteins in cancer cells

Better diagnosis and treatment of cancer could hinge on the ability to better understand a single cell at its molecular level. New research offers a more comprehensive way of analyzing one cell’s unique behavior, using an array of colors to show patterns that could indicate why a cell will or won’t become cancerous.

A University of Washington team has developed a new method for color-coding cells that allows them to illuminate 100 biomarkers, a ten-time increase from the current research standard, to help analyze individual cells from cultures or tissue biopsies. The work is published this week (March 19) in Nature Communications. (more…)

*Berkeley Researchers Provide Detailed Look at Proteasome’s Regulatory Particle*

Important new information on one of the most critical protein machines in living cells has been reported by a team of researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. The researchers have provided the most detailed look ever at the “regulatory particle” used by the protein machines known as proteasomes to identify and degrade proteins that have been marked for destruction. The activities controlled by this regulatory particle are critical to the quality control of cellular proteins, as well as a broad range of vital biochemical processes, including transcription, DNA repair and the immune defense system.
