Pair of cancer genes found to drive both cell migration and division

...archers have found that two genes already known to control cell movement are also needed for proper cell division. They report their findings in the April issue of Developmental Cell. The researchers discovered that the two genes are required for a dividing cell's halves to separate, raising the possibility...

Newly discovered protein an important tool for sleeping sickness research

...y of JBP2, a member of a protein family that helps control DNA-related functions, is a significant breakthrough in this quest because Sabatini and his colleagues were able to demonstrate that the protein is the key regulator of base J synthesis. This will provide the scientists a new tool to elucidate the bi...

Active Vaccine Prevents Mice From Developing Prion Disease

...time, the diseased animal develops dementia, loses control of its limbs, and eventually dies. There are no treatments for prion-related diseases, and prions can easily infect the body because they do not elicit any immune response. To create a vaccine that could rally the immune system of mice, the NYU res...

Beneficial Beetles Battle Pesky Saltcedar

...rought into the United States in the 1800s to help control erosion. By the mid-1900s, however, saltcedar had become an out-of-control pest, crowding native plants, such as cottonwoods and willows, along streambanks and river channels throughout the American West. Agricultural Research Service (ARS) entomolo...

Scientists find viruses can't stick to sea bugs in the dark

...ealth of the seas. "Research using cyanophages to control blooms of cyanobacteria must take light into consideration," explains Ying Jia. Algal blooms can use up the oxygen in water and block out the sunlight that other organisms need to live. "If there is not sufficient light, the spread of the phage might...

Whole genome promoter mapping - Human Genome Project v2.0?

...he protein-coding genes in the human genome, their control sequences have been elusive until now. "Promoters are a type of genetic switch that turn gene expression on or off. If we know where the promoters are, we can study how the genetic switches work in a cell, and investigate their connection to human di...

While gliding, these snakes make turns up to 90 degrees and always seemed to land without injury. The researchers now ...

Gene silencing technique offers new strategy for treating, curing disease

...ruses and bacteria make RNA sequences like this to control gene expression," Dr. Corey said. So far, the researchers have inhibited the expression of nine different genes in cancer cell cultures. Dr. Corey said it's not clear whether the RNA is actually binding to the DNA itself, as the PNAs do, but it's cl...

Discovery of New Dopamine Action May Yield Alternative Psychiatric Drugs

If the two mechanisms control separate functions, particular drugs might target some dopamine-related behaviors and not others, thereby limiting the side effects of psychiatric therapy. Akt also plays important roles in many other processes in the body, including inflammation, c...
