Columbia research lifts major hurdle to gene therapy for cancer

...S), the researchers demonstrated thatthe technique works by incorporating it into a specially designedvirus. The virus eradicated prostate cancer cells in the lab and inanimals while leaving normal cells unscathed. Genetherapy based on the new technique should also be effective for a widerange of tumors -...

Controversial drug shown to act on brain protein to cut alcohol use

...k alcohol craving in rodents, andclarifying how it works in the brain. The new research findings aboutthe drug Ibogaine open the way for development of other drugs toreverse addiction without Ibogaine's side effects, potentially addingto the small arsenal of drugs that effectively combat addiction. Derive...

UW's Rosetta software to unlock secrets of many human proteins

...duct research into new drugs andtreatments.Rosetta works by virtually folding protein sequences into thousands ofpossible shapes, based on certain protein folding "rules" known byscientists. These rules are summarized in the program and are termedthe "Rosetta score." The program tries a great many conforma...

Scientists detect probable genetic cause of some Parkinson's disease cases

...Parkinson's disease.Further study of how this gene works also might help scientistsidentify new treatments."In addition to Dr. Singleton, the collaborative work was spearheaded byWilliam C. Nichols, Ph.D., of Cincinnati Children's Hospital, TatianaForoud, Ph.D., of Indiana University Medical Center, Indian...

Inexpensive, mass-produced genes core of synthetic biology advances at UH

...n the department of biology and biochemistryat UH, works at the leading edge of this field. Her recent findings onhow to mass produce multiple genes on a single chip are described in apaper titled “Accurate multiplex gene synthesis from programmable DNAmicrochips,?appearing in the current issue of Nature, ...

Bound for destruction: Ubiquitination protects against improper Notch signaling

... Taken together, these results suggestedthat Nedd4 works as an antagonist of Notch signaling at an early stage,prior to the proteolytic cleavage of the receptor’s intracellulardomain. Further investigation revealed the specific domain by whichNedd4 interacts with Notch and pinpointed the site of origin for...

Finding Cures For Tropical Diseases: Is Open Source An Answer?

...e the envy of the world, the commercial model only works ifcompanies can sell enough patented products to cover their R&Dcosts and produce profits for shareholders. The model thus fails in thedeveloping world, where few patients can afford to pay patented pricesfor drugs. The solution to this devastati...

Genome-wide mouse study yields link to human leukemia

.... "We are just beginning to figure out how it best works in humans, but simply knowing that we have a new target that may be meaningful in treating leukemia is a big step in the right direction." Grants from the National Cancer Institute and the Leukemia and Lymphoma Society supported the research. Addit...

Gene therapy converts dead bone graft to new, living tissue

... their bones for the calcium it needs. The process works both ways, fortunately, as another set of cells, called osteoblasts, rebuilds the bone when the body has excess calcium. In an average year, a healthy person may remove and rebuild 10 percent of his or her bone structure. This process of teardown an...

Study: Soap And Water Work Best In Ridding Hands Of Disease Viruses

...veness of hand hygiene products shows that nothing works better in getting rid of disease-causing viruses than simply washing one’s hands with good old-fashioned soap and water. Among the viruses soapy hand washing flushes down the drain is the one that causes the common cold. Other removable viruses caus...

Scientists develop new color-coded test for protein folding

...article folds or unfolds. The new technique, which works on the same principle as ordinary pH tests that measure the acidity of water, is described in the March 2005 issue of the journal Chemistry and Biology. "What we've developed is a simple and inexpensive sensor for determining when a protein changes ...

Same mutation aided evolution in many fish species, Stanford study finds

...iological changes. "We want to learn how evolution works on a large scale," he said. In previous work, his group found that several species of stickleback lacking hind fins all shared an alteration in how a gene was turned on and off. The striking similarity is that in both studies evolution turned to the...

UCSD discovery may help extend life of natural pesticide

...pesticide, perhaps even another variety of Bt that works through a different mechanism, could prevent the resistance genes from becoming widespread." According to the researchers, prior work indicates that there are other receptors that also contribute to Bt resistance. Combining pesticides that work thro...

NJIT Presidential Award winner takes stem cell research another step

...has caught the eye of the White House? First, she works with adult stem cells taken from adult bone marrow. So the controversy over the ethical implications of embryonic stem-cell research, in her case, is moot. An adult stem cell is an undifferentiated cell that builds and maintains tissues and organs, a...

Bird Brains Show How Trial and Error May Contribute to Learning
