Corals -- More complex than you?

...any as 20 or 25,000 genes, compared with the human complement of 20-23,000." Why a simple creature should have such a huge genetic repertoire is a mystery, but scientists are excited by it because corals are near the root of the family tree of all living animals and can throw new light on the origin of such ...

Fat screen delivers plant-derived chemical with antidiabetic effects

...pproach for treating insulin resistance that might complement the use of preexisting drugs and, more generally, provides validation for fat cell screens as a promising strategy for identifying new metabolic drugs, according to the researchers. While harmine itself has effects on the central nervous system th...

Warts vaccine -- 1 of many in pipeline

Genetic pathways to curable and incurable forms of pancreatic cancer identified

...se studies suggest is that it's not just the total complement of mutations that determines the behavior of these cancers but also the sequence in which the mutations arise." About 5 percent of all primary tumors of the pancreas, out of 40,000 annual new cases in the United States, arise from cystic tumors. ...

Carnegie Mellon University research shows how sensory-deprived brain compensates

... with a whisker on one side of its head and a full complement of whiskers on the other side. "These findings show us that a fully functioning set of whiskers on one side of the body dramatically inhibits the ability of a single whisker to remodel the brain," said Barth. "This finding suggests that we could ...

Scientists map air pollution using corn grown in US fields

... has been mapped using plants. This new method may complement existing air sampling techniques because plants provide a cost-effective way to record average daytime conditions over several months. Plants take in carbon dioxide gas, from both background and fossil fuel sources, during photosynthesis, and it beco...

NIH neuroscience microarray consortium launches high-throughput genotyping services

Novel laboratory technique nudges genes into activity

... team used strands of RNA that were tailor-made to complement the DNA sequence of a specific gene in isolated breast cancer cells. Once the RNA was introduced into the protein mix, the gene was activated, ultimately resulting in a reduced rate of growth in the cancer cells. Dr. Corey said that while it’s cl...

Supercomputing equipment to advance the frontiers of computational biology

...ersity Research (SUR) program, this Blue Gene will complement the $100 million partnership between Rensselaer, IBM, and New York state to create one of the world's most powerful university-based supercomputing centers. The equipment will provide a resource for scientists to gain experience with the Blue Gene c...

Two central mysteries in genome inheritance solved at UCSD

...the resulting daughter cells will lack the correct complement of genomic information ? a situation that is dangerous as it can promote cancerous transformation," said Desai. Cells avoid such a fate by detecting errors in attachment to the spindle, breaking down these defective attachments and starting over. ...

Neural stem cells lend the brain a surprising capacity for self-repair

...brain in which the SVZ resides. Without the normal complement of genes, that wall "disintegrated," he said, leaving holes in the brain. Surprisingly, they reported, the ventricular damage was eventually repaired. SVZ reconstitution and remodeling of the ventricular wall was driven by progenitor cells that esc...

Innovative movies show real-time immune-cell activity within tumors

...chers then designed a second set of experiments to complement the first. In the first set of experiments, the T cells were varied in two groups of mice while the target tumor cells were uniform. In the second set, the T cells were uniform while the tumor cells varied in two groups of mice according to whether o...

Cardiologist's 'living chip' changes science of disease monitoring

To create a first-generation Connectivity Map, the scientists measured the genomic signatures of more than 160 drugs and other biologically active compounds. They next developed a computer program to compar...

High-tech research shows cocaine changes proteins and brain function

... The researchers compared the proteome (the entire complement of proteins expressed at a given time) between the two groups by separating all of the proteins and then using high-throughput mass spectrometry which allowed the accurate identifcation of thousands of proteins simultaneously, Hemby said.
