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

...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 their genes for bre...

Green tea boosts production of detox enzymes, rendering cancerous chemicals harmless

... DNA, thus rendering them inert. They actually convert known carcinogens to non-toxic chemicals, and studies have shown a correlation between deficient expression of these enzymes and increased risk of developing some cancers, Chow said. Expression of this enzyme varies dramatically in people due to g...

New strategy for treating allergic disorders

...terium that has been used since time immemorial to convert milk into cheese and yoghurt. In the battle against chronic intestinal diseases, VIB researchers have been using L. lactis as a producer of a drug against gastroenteritis. The initial results of the clinical trials are promising. Now, the bacterium...

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

...e pancreas. Insulin is a hormone that is needed to convert sugar, starches and other food into energy. Insulin typically is given through shots and not pills so the hormone can go straight into the bloodstream. In Daniells method, plant cell walls made of cellulose initially prevent insulin from degrading...

Using stem cells to help heart attack victims

...to grow in the lab. "Our understanding of how to convert them into cardiomyocytes is poor. At the moment we only know how to produce a few million cardiomyocytes, but to treat just one heart attack patient, we may need one billion that all function in the correct way." To help overcome the many challenge...

System to analyze beating heart stem cells could lead to heart attack treatments

..., Dr Denning explains. Our understanding of how to convert them into cardiomyocytes is poor. At the moment we only know how to produce a few million cardiomyocytes, but to treat just one heart attack patient, we may need one billion that all function in the correct way. To help overcome the many challenge...

More fish oil, less vegetable oil, better for your health

...f extra fish oil that we added, COX-2 still helped convert all the vegetable oil available. This finding reveals for the first time a limit to how the body naturally regulates levels of prostanoids produced by fish and vegetable oil. If both oil types are present in the body, levels of prostanoids from fis...

UCLA study links air pollution to clogged arteries

... or stroke. The researchers next step will be to convert the genes responses to the pollutant-cholesterol combination into a biomarker that will enable physicians to easily evaluate air pollutions effect on health, especially cardiovascular disease. Once a biomarker is developed, wed simply need to test...

Cells take risks with their identities

...an author on the latest studywere recently able to convert mouse adult skin cells to embryonic stem cells by simply introducing four key genes. Given the right signals, inactive developmental regulators primed for transcription could roar to life. This is a new model for regulation of the developmental reg...

Homestake strikes gold again

... South Dakota, a strong supporter of the effort to convert Homestake into a research facility, released a statement in response to the NSF announcement which read in part: The NSF site selection process was rigorous and fair. On behalf of the citizens of South Dakota, Dr. Lesko and I encourage and welcome ...

Fat kills cancer

...ne cytosine deaminase into the cell. This gene can convert a less toxic drug, 5-fluorocytosine (5-FC), to 5-FU inside the stem cells, and the chemotherapy can then seep out into the tumor, producing a lethal by-stander effect. In nude mice animals with an inhibited immune system engrafted with human co...

American Chemical Society's Weekly PressPac -- June 27/July 3, 2007

...e tumor. Once inside the tumor cell, the compounds convert from an inactive form into an active anti-cancer drug. The chemistry involves attaching platinum compounds to single wall carbon nanotubes (SWNTs), one-atom thick sheets of graphite rolled up into a cylinder with a diameter about 50,000 times small...

Pairing nanoparticles with proteins

...ientists have been searching for efficient ways to convert organic fuels such as ethanol into electricity using catalytic electrodes. But making single layers of densely packed enzymes, the functional part of such catalytic electrodes, has been a challenge. This new research shows that precisely engineered g...

Biotech breakthrough could end biodiesel's glycerin glut

...conditions that allow a known strain of E. coli to convert glycerin into ethanol," said chemical engineer Ramon Gonzalez. "It's also very efficient. We estimate the operational costs to be about 40 percent less that those of producing ethanol from corn." Gonzalez said the biodiesel industry's rapid growth ...

Scientists call for global push to advance research in synthetic biology

...ers solutions to these issues: microorganisms that convert plant matter to fuels or that synthesize new drugs or target and destroy rogue cells in the body. The two-page statement calls for an international effort to advance synthetic biology that would not only propel research, but do so while developing p...

Modified mushrooms may yield human drugs

...ith mushrooms, we can use commercial technology to convert the vegetative tissue from mushroom strains stored in the freezer into vegetative seed. A crop from which drugs may be extracted could be ready in weeks," Dr. Romaine said. A mushroom-based biofactory also would not require expensive infrastructure s...

UVa researchers restore genes in human inner ear cells

...d insulin resistance. Uncoupling proteins act to convert stored fat into thermal energy. In the current study the authors began by showing that mice fed a high-fat diet were markedly insulin resistant, a result of defects in insulin signaling in skeletal muscle and liver. In contrast, mice overexpressing U...
