With record resolution and sensitivity, tool images how life organizes in a cell membrane

...ither ''short'' or ''tall'' chemical structures to create phase domains, or membrane features that they could study. Tall lipids, red in illustrations in the paper, melted at higher temperatures than short lipids, represented by green. The researchers melted the lipids together, then placed them on a surfac...

Scientist works to improve treatment for brain tumors

.... Debinski combined IL13 with a bacterial toxin to create a cytotoxin drug to target cancer cells and less healthy cells. The efficacy of the first generation of the drug has been has been tested in a clinical trial (phase III) involving 190 patients at 40 different medical centers worldwide. The results ar...

Genetic 'roadmap' charts links between drugs and human disease

...ent of genes that the drugs turn on and off. 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 compare the signatures of the drugs with each other and also...

Scientists resuscitate a 5 million-year-old retrovirus

... Retroviruses, whose genomes consist of RNA, can create DNA "copies" of the RNA genomes and incorporate them into the genomes of their hosts. Phoenix belongs to a sub-category of retroviruses--known as HERVs (human endogenous retroviruses)--which inserted copies into the human germline millions of years ...

Ghost protein leaves fresh tracks in the cell

...nt cells. The hope is that researchers may one day create therapeutic molecules to compensate for genetic lesions in diseases such as hereditary anemia, Duchenne muscular dystrophy, cardiac arrhythmia and the degenerative brain disease spinocerebellar ataxia 5. "As we learn more about mutations involving ...

Mayo Clinic Cancer Center: Harnessing the measles virus to attack cancer

...se," says Dr. Russell. "From basic scientists who create and test the vaccine strain to those who determine the best way to manufacture a safe biological delivery mechanism, and finally, to clinicians who understand the science and develop guidelines by which the study is conducted and correctly carried ou...

Amgen introduces comprehensive financial assistance programs for cancer patients

...chief executive officer at Amgen. "Our goal is to create the most comprehensive oncology access program in the industry, and we are starting with Amgen Oncology Assistance. To ensure patients have access to Vectibix, we have priced it at approximately 20 percent less than the other antibody on the market ...

New angiogenesis finding may help fight cancer growth

...ment. Before solid tumors start to grow, they must create a new blood supply, and since adults need angiogenesis only during pregnancy and to heal wounds, blocking angiogenesis could be a promising way to halt tumor growth. Also in June, the FDA approved a compound that inhibits VEGF for treating colon canc...

Bacteria could make new library of cancer drugs that are too complex to create artificially

... potential anti-cancer drugs that are difficult to create synthetically on a lab bench. The bacterium Strep...at allows the bacterium Streptomyces coelicolor to create streptorubin B and have gained a clear understanding of which are the key enzymes that act at partic...

Light-sensitive photoswitches could restore sight to those with macular degeneration

...a," Isacoff said. "We plan to develop the tools to create a new layer of optically active cells for the retina." Loss of photoreceptors - the light detectors in the retina - is the major cause of blindness in the United States. One in four people over age 65 suffers vision loss as a result of this conditi...

Free radical cell death switch identified

...e radicals are not destroyed by antioxidants, they create oxidative stress. As the body ages, it produces more and more free radicals and its own antioxidants are unable to fight this process, which results in the generation of highly reactive oxygen molecules that inflict cellular damage by reacting with ...

Tests may help answer questions about GMOs and allergies

...he original crop's genome. This is usually done to create a plant that is more resistant to insects or diseases. The Food and Agriculture Organization within the World Health Organization has a structured approach to determining whether genetically engineered foods cause allergies, according to Gangur, who...

Unique soybean lines hold promise for producing allergy-free soybeans

...ad successfully used a gene-silencing technique to create a soybean line in which P34 was "knocked out." However, because of public resistance to genetically modified products researchers have been seeking a more traditional approach. Because the newly identified lines occur naturally, they can be successfu...

Weizmann Institute scientists discover a molecular security mechanism for keeping mutations in check

... genetic material and copying as it goes along, to create new DNA that will be passed on to the daughter cell at cell division. This enzyme can be a stickler for accuracy ?if it runs into damage from radiation or exposure to harmful substances on the DNA strand, it can stop in its tracks, unable to continue...

The ability to readily create transgenic chickens through this technology, and then to scale up production through conventional breeding further adds to the practicality of this technology for large-scale production of therapeutic proteins." In the early embryo, only a few cells...

'LEGO-Like' building blocks to halt cell growth wins Hebrew University prize

...of peptides and scaffold design, it is possible to create a synthetic molecule that will bind to the IGF-1 (insulin-like growth factor-1) receptor. IGF-1 is a protein that plays a critical role in the proliferation of many cancers, including prostate, lung, breast, colon and brain cancers. The binding actio...
