Computational Method Speeds Mapping of Cell Signaling Networks

... This application would be particularly useful for understanding disease states where signaling malfunction plays a prominent role, including cancer and autoimmunity. Until now, the large amounts of data the technique requires prevented its application to protein networks. Being able to monitor multiple component...

New insight into regulation of blood stem cells

Scientists have made a significant advance toward understanding the regulation of blood stem cells and the complex, lifelong process of blood cell formation. A research study published in the February issue of Developmental Cell expands on previous studies by using adult animals to examine the role of a key gene ...

Birds brains reveal source of songs

...n Research at MIT now have come one step closer to understanding that process. They've shown for the first time how a particular brain region in birds serves as the source of vocal creativity. "It's an extraordinary finding," says Sarah Bottjer of the University of Southern California. "Here's an organism that en...

Chemicals in tattoo inks need closer scrutiny

Navigating an integrated yeast network

...ast cell in a simple graphical form, enhancing our understanding of how the networks of interaction by which components of a cell influence one another. New research published in the Open Access journal Journal of Biology shows that such maps can also reveal cryptic interactions and enable accurate predictions abo...

Disease diagnosis, biodefense among UH chemical research projects

...His group's poster presents progress toward better understanding of the chemical and physical driving forces of carbohydrate-protein interactions that are important in biological systems. # Roman S. Czernuszewicz, associate professor of chemistry, will present research on "Resonance Raman spectroscopy of nitropho...

Scientists identify genetic pathways essential to RNA interference

...sion in cancer." The researchers note that better understanding the mechanisms underlying RNAi could help transform what has been a research tool into a powerful therapeutic tool. Although the process has worked well in studies of cultured human cells, it has not yet been effective for experimentally suppressing ...

Brain-mapping technique aids understanding of sleep, wakefulness

...r neurons in the brain is an important step toward understanding how and why we sleep. Mapping the neurons to which orexin neurons send signals has been relatively easy, Dr. Yanagisawa said, but determining which neurons send signals to orexin neurons has been a challenge. A brain-mapping technique developed rece...

White Blood Cell 'Waste Disposal' System Plays Critical Regulatory Role

... actively linked to neutrophil production. A clear understanding of the processes that control neutrophil turnover may contribute to the development of future therapeutics for conditions characterized by abnormal numbers of these critical immune cells. Human neutrophils are white blood cells that are constantly b...

New understanding of DNA repair may pave way to cancer treatments

...laboratory has been studying ATF2 with the goal of understanding its role in regulation of cell cycle and programmed cell death. These studies evolved from the finding that ATF2 has an important role in the development and progression of melanoma tumors. Inhibition of ATF2 was found to sensitize melanoma to variou...

Cerebral navigation: How do nerve fibers know what direction to grow in?
