Ian Dworkin, an assistant professor of zoology, worked with a on the paper Genetics of Microenvironmental Canalization in Arabidopsis Thaliana the group tackled the question of canalization -- a measure of the ability of...

Gene regulation, not just genes, is what sets humans apart

... The sugars in their diet are relatively simple to break down and convert to cellular fuel. Humans, on the other hand, eat a wider array of foods, including many the chimps would simply not be able to digest like starchy root crops. The researchers found dramatic differences in the regulatory regions of th...

OHSU turns mouse into factory for human liver cells

...from laboratory animals because liver enzymes that break down these compounds are species specific. "Animal liver cells process drugs quite differently than human liver cells do," he said. Another obstacle for drug companies is the human liver cell market is filled with poor-quality or nonviable cells i...

High-intensity ultrasound may launch attack on cancer, wherever it lurks

...de, with emphasis on using mechanical vibration to break apart the tumor cells, may have an even more significant impact in suppressing cancer metastasis by waking up the immune system. For reasons that are still not completely understood, cancer cells often go largely undetected by the immune system, Zh...

Under magnetic force, nanoparticles may deliver gene therapy

...osing the nanoparticles are biodegradable, so they break down into simpler, nontoxic chemicals that can be carried away in the blood. Previous researchers had shown that magnetically driven nanoparticles could deliver DNA in cell cultures, but ours is the first delivery system that is biodegradable, and th...

Insulin grown in plants relieves diabetes in mice; UCF study holds promise for humans

...e intestine, bacteria living there begin to slowly break down the cell walls and gradually release insulin into the bloodstream. Currently, the only relief for diabetes is a momentary relief, Daniell said. Diabetics still have to monitor their blood and urine sugar levels. They have to inject themselves ...

Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...ies have shown that FP-23 fuses with, and can even break apart, blood cells and other man-made, cell-like structures called liposomes. FP-23 likely plays several roles in viral fusion, according to the researchers. One role already suspected is that FP-23 attaches to its T cell victim to facilitate a cha...

Switchable adhesive

...strongly acidic (a pH value of about 1), the bonds break up, the basic groups lose their charge, and the electrostatic attraction lets up. The two surfaces can then be slowly and carefully separated from each other without any damage. This detachment is reversible: If the pH value is raised again, making t...

New role for protein in fat cells may improve understanding of obesity and diabetes

...oplets and not in the ER, cells low in CETP cannot break down the fats they store as effectively, Morton and Izem say. The scientists conclude that CETP is probably essential for lipid metabolism and storage in fat cells and that fat tissue is not only an energy storage tissue but also a major endocrine...

Exercise, exercise, rest, repeat -- how a break can help your workout

Bethesda, Md. (July 18, 2007) Taking a break in the middle of your workout may metabolize more fat than exercising without stopping, according to a recent study in Japan. Researchers conducted the first known study to compare these two exercise methodsexercising continually in one long bout ve...
