Four-protein complex provides new target for thwarting cancer migration, invasion

The molecular machinery that switches on a gene known to cause breast cancer to spread and invade other organs has been identified by an international team led by scientists at The University of Texas M. D. Anderson Cancer Center. The paper was published Sunday in Nature Cell Biology's advanced online publication.

Researchers find how KEAP1 tumor suppressor works

A tumor-suppressing protein snatches up an important cancer-promoting enzyme and tags it with molecules that condemn it to destruction, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports this week in the journal Molecular Cell.

TRAF6 protein plays a role in cell growth and carcinogenesis, says researchers

The mainstay immune system protein TRAF6 plays an unexpected, key role activating a cell signaling molecule that in mutant form is associated with cancer growth, researchers at The University of Texas M. D. Anderson Cancer Center report in the Aug. 28 edition of Science.

Research looks at cellular stress response to low oxygen

Gary Chiang, Ph.D., and colleagues at Burnham Institute for Medical Research (Burnham) have elucidated how the stability of the REDD1 protein is regulated. The REDD1 protein is a critical inhibitor of the mTOR signaling pathway, which controls cell growth and proliferation.

Discovery of novel mechanism that could be targeted to prevent cancer spread

Researchers have discovered a key to the function of a specific protein that helps control the levels of other critical proteins within cells, including a protein that suppresses the spread of cancer. The new information about the mechanism of action of the protein, called gp78, may enable researchers to explore new types of therapies to prevent the spread of cancer. The study, by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, was published in the June 26, 2009, issue of Molecular Cell.

New protein identified in bacterial arsenal

Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells' normal activities but ultimately co-opting them to serve the bacteria's needs.

Possible new therapeutic target for pancreatic cancer

A possible new therapeutic target for pancreatic cancer, the most lethal form of human cancer, has been identified in the proteins whose DNA recipe comes from gene, "Seven-In-Absentia," according to researchers at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Research provides new insights into how cells accessorize their proteins

St. Jude Children's Research Hospital investigators have gained new insight into how the cell's vast array of proteins would instantly be reduced to a confusion of lethally malfunctioning molecules without a system for proteins to "accessorize" in order to regulate their function.

Researchers discover key details of how rheumatoid arthritis destroys bone

Researchers have discovered key details of how rheumatoid arthritis (RA) destroys bone, according to a study published in the Aug. 22 edition of the Journal of Biological Chemistry. The findings are already guiding attempts to design new drugs to reverse RA-related bone loss and may also address more common forms of osteoporosis with a few adjustments.
