With an eye on safety, UF experts explore cellular mechanisms of gene therapy

...is might occur would be if the new DNA was able to effectively switch on a previously silent tumor-causing gene." In studies in people and animals conducted during the past decade, UF scientists have never seen tumor development associated with AAV-delivered gene therapy, but they wanted to make sure that wasn't...

...his large award," said Mann. "It means that we are effectively helping people find new treatments for a wide variety of medical conditions." "The GCRC provides an engine to foster rapid progression of research into practical applications for improving human health," said Charles E. McCall, M.D., professor and v...

Small streams contribute far more than previously thought to cleaning waterways

...greater care to insure that small streams can work effectively to clean the water will reduce the overall nitrogen load that makes its way into larger bodies of water. "It doesn't mean that you can ignore your sewage treatment plants, but if we can do better with our small streams and do some restoratio...

Dr Ramakrishnan continued: "Although these antibiotics were discovered several decades ago, we haven't understood in detail how they work." Recently, several groups of researchers have been developing high resolution...

Key step in gene activation discovered

...in the process of rearranging the shape of a gene, effectively unlocking its genetic code. One is a molecule nicknamed "SWI/SNF" and the other is a molecular family nicknamed the "HATs." Like a pack of comicbook superheroes, each with a different power, the team of molecules that control the use of a gene's c...

Taming chaos? German scientists force checkerboard patterns from turbulence, suggesting better control strategies

...ailov and others. "Chemical turbulence can be very effectively controlled by our approach." In theory, said Ertl, director of the department of physical chemistry at the Fritz Haber Institute: "It may be possible to increase the selectivity of various reactions, to improve the yield of a desired product. There m...

Welch honors Kornberg for insights into DNA transcription

...dge ultimately will allow scientists to apply more effectively the results of the human genome project to better understand disease. Today, The Welch Foundation announced that Dr. Kornberg will receive its 2001 Welch Award, a $300,000 prize given for lifetime achievements in basic chemical research, in recogniti...

UF researchers reverse metabolic disorder in mice

...road to a cure: In male laboratory mice, they have effectively reversed the condition with a single treatment of gene therapy. The findings raise the hope that as the science progresses in coming years, people with the disorder will no longer have to shun so much of the typical human diet, including meat, fish, ...

AIDS in Africa has potential to affect human evolution, UC Berkeley scientists report

...rcent. The shift in frequency of these genes would effectively lengthen the average latency by one year, from 7.8 years to 8.8 years. The frequency shift is primarily due to the opportunity for continued reproduction during the extra two to four years, allowing those with the resistant version of the gene, or al...

Wiley, UNO associate professor of chemistry, who is also a member of the AMRI/UNO team. The project will focus on the design and fabrication of electromagnetic m...

UT Southwestern researchers show tumor-suppressor genes linked to insulin signaling

...produce and grow so quickly, gene functions can be effectively studied in less time than other animal models. "We found that the TSC genes are negative regulators of the insulin pathway because when we omit the TSC genes, insulin signaling increases, and thus results in larger cells," Pan said. "The opposite is ...

Structural studies reveal how potassium channels are inactivated

...so explain why drugs that block potassium channels effectively have structural features that resemble the inactivation gate peptide. The structural resemblance can cause serious side effects. Antibiotics with these features tend to block potassium channels found in the heart and can cause arrhythmias, MacKinnon ...

Nuclear waste disposal: A safer solution?
