Gene Vaccine Protects Mice Against Development Of Her2/neu Breast Cancer

... studies, a novelvaccine that uses immune cells as factories to produce Her2/neu proteinmay offer a way to treat some human breast cancers, say researchers atThe University of Texas M. D. Anderson Cancer Center. [Ed : Her2/neu is a protein often present / surexpressed in breast cancer ]Their study, publishe...

A comprehensive response to HIV could prevent 10 million AIDS deaths in Africa by 2020

Specialized immune-system B cells play double-barreled role

...ment of vaccines, they said. B cells are the arms factories of the immune system, producing antibodies that target invading microbes for destruction. Generally, B-1 cells have been thought to play a major role in the innate immune response -- the type of immunity that offers rapid, generalized responses to in...

Scientists turn tobacco against cancer

...r into tobacco plants. The plants, in turn, become factories churning out antibody. The report appears online this week in the Proceedings of the National Academy of Sciences. Standard mouse-made monoclonals recognize a particular type of protein antigen on human colorectal cancer cells and have been used in ...

Scientists devise way to measure RNA synthesis on the fly in a live cell

...s as an important intermediary between DNA and the factories throughout the cell that produce proteins. Some biologists have recently begun to identify families of RNA molecules that also play a major role in determining when and how genes are turned on and off, but they have lacked the ability to monitor acti...

Study provides insight into cellular defenses against genetic mutation

...a modified copy of DNA, is transported to cellular factories called ribosomes that receive instructions for building proteins by "reading" mRNA templates. Over time, genes evolve to show changes in their makeup. Some changes, or mutations, have no impact, some provide advantages making organisms more likely t...

Animals can change genes quickly to keep up with viral ingenuity

...hijack the cells of other organisms, using them as factories to copy themselves. Animals and plants have a number of different locks and codes that help to keep the viruses out, but viruses are capable of evolving new ways of breaking the codes extremely quickly. The new research shows that genes controlling a...

Plant-derived vaccines safeguard against deadly plague

...ully turned tobacco plants into vaccine production factories to combat the deadliest form of plague. The vaccine elicits a protective immune response in guinea pigs. The results are considered to be a milestone in the future development of a new vaccine for human use. Plague, caused by a rod-shaped bacterium ...

Computational model simulates AZT metabolism in mitochondria

...th DNA replication in the mitochondria, the energy factories of our cells, and can lead to potentially fatal side effects in patients undergoing HAART treatment. Samuels, assistant professor at VBI, commented: "HAART is one of the biggest success stories in modern medicine. The goal of our work is to help im...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...nment. It also could improve monitoring systems in factories and other industrial operations where potentially hazardous chemicals are in use. The research can accelerate the development of microfluidic devices that would, for instance, allow as many as 20 to 30 various tests to be performed using a single, ...

Drug dials down the energy within cells, UM researchers find

... targets an enzyme inside mitochondria, the energy factories of cells. The specific enzyme, F1F0-ATPase, is responsible for producing most of the cell's ATP. That's a critical role because ATP, often referred to as the cell's energy currency, is the molecule that captures chemical energy from food and transfer...

Acid rain causing decline in sugar maples, say researchers

...ental consequence of burning fossil fuels, running factories and driving cars, has altered soils and reduced the number of sugar maple trees growing in the Northeast, according to a new study led by Cornell University researchers. The sugar maple is the most economically valuable tree species in the eastern ...

Gene therapy prevents the onset of diabetic symptoms in mice

Different strategies underlie the ecology of microbial invasions

...idemic among susceptible competitors, which become factories producing more parasites. Amplification therefore makes phage carriers able to successfully compete with phage-susceptible bacteria even faster when the carriers are rare, whereas chemical killers can only win in a well-mixed environment when chemica...

Biologists probe the machinery of cellular protein factories

...proteins is carried out by ribosomes, tiny protein factories humming away inside the cells of all living things. Harry Noller, the Sinsheimer Professor of Molecular Biology at the University of California, Santa Cruz, has been studying the ribosome for more than 30 years. His main goal is to understand how t...

Walking molecule now carries packages

It was included in the American Institute of Physics "Top 25 Physics Stories for 2005." The new molecule carrier runs on a copper surfa...

Cheaper, better disease treatments expected from faster approach to developing antibodies

However, previous approaches required an antibody that looked promising to be transferred from bacteria to mammalian cells to pur...

Molecular differences between early and advanced melanomas could provide new drug targets

... an increase in impaired mitochondria-- the energy factories of cells. Their research showed, however, that these mutations in mitochondria were likely the result of the prolonged exposure to increased oxidative stress caused by Akt overexpression, but that the mitochondrial mutations were not essential for th...

Bypassing eggs, flu vaccine grown in insect cells shows promise

...re systems to grow vaccines ?using viruses as tiny factories to churn out mass amounts of vaccines ?is a growing business. A similar technology using human cell lines is used to produce the hepatitis B vaccine, while one form of a vaccine against human papilloma virus is made using the same insect cell line us...
