Molecular machine may lead to new drugs to combat human diseases

...ds of other introns in the same family and provide possibilities for new treatments for a wide variety of diseases, she said. Other scientists now will use the information gleaned from this study in an attempt to develop new drugs, Golden said. Introns were unknown until the late 1970s, and scientists are still ...

Yale Scientists Find MicroRNA Regulates Ras Cancer Gene

...r gene is regulated in lung cancer, presenting new possibilities for diagnosis and treatment. The work is reported in March issues of the journals Cell and Developmental Cell. The oncogene Ras is out of control in about 20 percent of cancers where it is over-expressed or activated by mutation. According to Slack,...

New SARS Protein Linked To Important Cell Doorway

...he power of genetic information to rapidly advance possibilities for patient treatment. If further investigation shows orf7a is important to the SARS virus' ability to cause disease, scientists will already have much of the knowledge they need to develop ways to disable or weaken it. "The key to studying novel vi...

Medical molecules designed to respond to visible light that can penetrate tissue

... release drugs at disease sites in the body. Such possibilities will be discussed in a poster and a talk by Virginia Tech researchers presenting at the 229th American Chemical Society national meeting in San Diego on March 13-17. Researchers in Karen Brewer's group at Virginia Tech have designed supramolecular c...

...utrition and degrading pollutants, and calculating possibilities for life in pressurized environments elsewhere in the solar system. “These organisms live in a world that is physically very different from the skin of the planet in which we humans reside,?said Bartlett, who is part of the Scripps Marine Biology Re...

Supercomputers to focus brains on AIDS dilemma

...emergence of drug-resistant mutants. The new drug possibilities flow out of a long series of molecular dynamics simulations by McCammon's group. These simulations have focused on the catalytic domain of HIV-1 integrase, and relied on the large-scale computational resources of the San Diego Supercomputer Center (S...

The DOE JGI is currently producing nearly one-quarter of the number of microbial genome projects worl...

Sponges as drugs

...ch researcher Nicole de Voogd has investigated the possibilities for rearing sea sponges in Indonesia. Some of these sponges contain substances of interest to the pharmaceutical industry. As these are increasingly difficult to obtain, there is growing interest in alternative methods of exploitation, such as rearin...

Recombinant DNA technology may enable oral, rather than injectable, delivery of protein drugs

...ately, Shen and colleagues began to reconsider the possibilities of oral drug administration. Their first breakthrough came when they began to recognize the potential uses of transferrin. "We discovered that transferrin can bind to receptors on the intestinal epithelial cells and be transported across the GI trac...

Achilles heel of the herpes virus possibly found

... good at entering so many kinds of cells. The many possibilities for virus binding to cells make deciphering the entry process a difficult problem to solve. The gene that encodes B5 had in fact been sequenced, but not characterized, as part of the Human Genome Project. Discovering its role and studying the HSV en...

Nanowires can detect molecular signs of cancer, scientists find

.... It's a device that could open up substantial new possibilities in the diagnosis of cancer and other complex diseases." Lieber and his colleagues linked slender nanowires conducting a small current with antibody receptors for certain cancer markers -- such as prostate specific antigen (PSA), PSA-a1-antichymotryp...

Evolution of life on Earth may hold key to finding life in outer space

...Science (HMNS) on a film project that explores the possibilities of life on other planets. Partially funded by an education and public outreach supplement to Fox's NASA grant, the joint production between HMNS and UH, called "Fantasy Worlds: Exploring the Limits of Life," is playing at the Burke Baker Planetarium ...

New study shows SARS can infect brain tissue

...y have done more harm than good. There are a few possibilities for curbing Mig's possible role in causing brain damage in SARS patients with central nervous system infection, according to lead author Jun Xu, PhD, of the Guangzhou Institute of Respiratory Diseases and senior author Yong Jiang, PhD, of the Key Lab...

Researchers discover new tumor defense system

...ey Pines Institute for Molecular Studies raise the possibilities of new therapeutic targets for cancer, such as those that may transport free fatty acids out of the tumor. Alternatively, free fatty acid levels in the blood could be used to help gauge the aggressive potential of a tumor. ...

Study shows big game hunters, not climate change, killed off sloths

... and mammals -- used to live there, we can open up possibilities for restoring parts of these islands to something near their original condition," he said. The only reason the living species of sloths survive is that they live high up in trees, where their green-algae-colored fur camouflages them, Steadman said. ...

New study shows measles immunization may prevent fatal brain infection

...clinical guidelines on reporting infections. Other possibilities include a higher incidence of measles during the 1989-1991 resurgence in the population with the highest risk for SSPE, namely children under the age of five, or because wild-type viruses of the genotype identified are more likely to cause SSPE. Th...

Method slashes quantum dot costs by 80 percent

...few nanometers in diameter. Most of the commercial possibilities discussed for quantum dots - bioimaging, color displays, lasers, etc. - relate to their size-controlled fluorescence. For example, CdSe quantum dots have the ability to absorb high-energy photons of ultraviolet light and re-emit them as photons of vi...

K-State professors discover enzyme responsible for creation of a beetle's hard shell

...ase-2 as the catalyst for cuticle tanning opens up possibilities of targeting this protein as a way of weakening the beetle's physical defenses against mechanical, chemical and biological injuries, Muthukrishnan said. Better insecticides could be developed as a result of having a more insect-specific target like l...
