Massey Cancer Center researcher helps to identify a piece of the cancer puzzle

12.05.2005


Publication reveals atomic structure of angiopoietin-2, a key protein involved in the neo-vascularization of solid tumors



A structural biologist from the Virginia Commonwealth University Massey Cancer Center, in collaboration with researchers at Memorial Sloan-Kettering Cancer Center, has identified the crystal structure of a protein that plays a role in supplying nutrients to solid tumors.

This identification may help researchers gain a greater understanding of the cell signaling that occurs when cancer cells try to co-opt nearby healthy cells into helping to feed and spread growing tumors.


The structure of the protein, Ang2, will be published this week in "Structure" a peer-reviewed scientific journal. "By examining structures of proteins and learning how they interact with each other, we can better explore how to turn off the signals that promote cancer growth," said William A. Barton, Ph.D., a VCU alumnus who recently returned to Richmond to continue his research.

"Once we understand the shape and characteristics of proteins involved in tumor growth and development, researchers can identify therapeutics that may eventually lead to cures for cancer."

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
