Researchers find pathway that controls cell size and division
07-30-2007 · EurekAlert!Researchers at Washington University in St. Louis have discovered through genetic analyses a metabolic pathway in bacteria comprised of just three genes, all known to be players in metabolism. This pathway was previously shown to be involved in synthesizing modified membrane lipids but the Petra Levin lab's data indicates it also has a major role in cell division. This is the first identification of a pathway responsible for regulating bacterial cell size.

- Mayo discovers protein as potential tactic to prevent tumors
10-12-2006 · EurekAlert!
Mayo Clinic researchers have found that a protein that initiates a "quality control check" during cell division also directs cell death for those cells damaged during duplication. This knowledge represents a potential "bulls eye" for targeting anti-tumor drugs. The findings appear in the current issue of Science.

- New protein inhibitor impedes growth of cancerous cells
02-08-2007 · EurekAlert!
Researchers have developed a small-molecule inhibitor of a protein that plays key roles in the control of cell division, and they show that the inhibitor can halt the growth of tumors in mice and cancer-derived cells growing in culture.

- Researchers Uncover Critical Player In Cell Communication
10-06-2006 · ScienceDaily
Johns Hopkins researchers have teased out the function of a protein implicated in Williams-Beuren syndrome, a rare cognitive disorder associated with overly social behavior and lack of spatial awareness. Called TFII-I, or TF "two eye," the protein long known to help control a cell's genes also controls how much calcium a cell takes in, a function critical for all cells, including nerves in the brain. The study will be published this week in Science.

- 2-protein team would be lost without each other
04-19-2007 · EurekAlert!
Just as a hard-charging person sometimes needs a calming partner to be more effective, so it is with a pair of critical proteins that promote cell division and growth in the rapidly expanding root tip of plants. This emerging picture of the complex interplay between genes and proteins is the latest finding to come from Duke University researchers' examination of the model mustard plant Arabidopsis thaliana.

- Hot on the TRAIL of controlling inflammation in bacterial meningitis
06-14-2007 · EurekAlert!
In a study appearing online on June 14 in advance of publication in the July print issue of the Journal of Clinical Investigation, researchers at Charité-Universitätsmedizin Berlin report that the molecule known as TRAIL can limit excessive immune responses in bacterial meningitis, and as such may be of use to control inflammation of the spinal cord and brain, which causes brain cell death in this life-threatening disease.

- Penn researchers discover how microRNAs control protein synthesis
07-09-2007 · EurekAlert!
While most RNAs work to create, package and transfer proteins as determined by the cell's immediate needs, miniature pieces of RNA, called microRNAs (miRNAs) regulate gene expression. Recently, researchers from the University of Pennsylvania School of Medicine determined how miRNAs team up with a regulatory protein to halt protein production.

- Study reveals how stem cells decide to become either skeletal or smooth muscle
10-10-2007 · EurekAlert!
Researchers have discovered that a key protein controls how stem cells 'choose' to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels. The results suggest new ways to treat atherosclerosis and cancer, diseases that involve the creation of new blood vessels from stem cell reserves that would otherwise replace worn out skeletal muscle.

- Gene Key To Taste Bud Development Identified
10-02-2006 · ScienceDaily
Scientists have identified a gene that controls the development of taste buds. The gene, SOX2, stimulates stem cells on the surface of the embryonic tongue and in the back of the mouth to transform into taste buds, according to the researchers. Stem cells are immature cells that can develop into several different cell types depending on what biochemical instructions they receive.

- Jefferson scientists find guardian gene's choices crucial to stopping cancer process
01-05-2007 · EurekAlert!
Scientists at the Kimmel Cancer Center at Thomas JeffersonUniversity have uncovered a novel pathway by which the anti-cancer gene p53 springs into action, protecting a damaged cell from becoming cancer. The gene can either halt the cell's growth or send it spiraling toward certain death. How this choice is made, the researchers say, could have implications for future strategies in chemotherapy drug development.
