Arthritis drug suppresses cancer development by stopping action of key protein

... stop a key transcription factor known as Sp1 from turning on multiple genes in cancer cells known to be associated with cancer growth. One of those genes triggers production of vascular endothelial growth factor (VEGF), the predominant angiogenic factor that leads blood vessels to grow to feed tumors. The ...

Genetic risk factor for Parkinson disease discovered

...tein differing by only one protein building block, turning the amino acid threonine into an alanine, may change its function slightly. The result, they say, could affect one's ability to process damaging oxygen free radicals that are a side effect of energy production. People carrying the J variant may be be...

Transgenic trees hold promise for pulp and paper industries

The expensive, energy-intensive process of turning wood into paper costs the pulp and paper industries more than $6 billion a year. Much of that expense involves separating wood's cellulose from lignin, the glue that binds a tree's fibers, by using an alkali solution and high temperatures and pressur...

Europes population has developed new tendency to shrink, Science study reports

...ment of Science (AAAS). The year 2000 marked a key turning point for Europe, reports the research team, led by Wolfgang Lutz of the Austrian Academy of Science, in Vienna, and the International Institute for Applied Systems Analysis, in Laxenburg, Austria. That year, the population's "momentum" flipped from...

Rockefeller scientists identify 'natural' proteins that push stem cells to produce hair, not skin

...chers can study the genes and proteins involved in turning stem cells into epidermis or hair follicles. Fuchs and her research team previously discovered that a protein called beta-catenin is a key player in formation of hair. This finding has contributed to the recognition that accumulation of this protein ...

Scientists find new way to grow human embryonic stem cells

...the primitive human ES cells, preventing them from turning into more "grown-up" cell types, such as bone, fat, or brain cells. The Johns Hopkins team found that human marrow stromal cells can also act as feeder cells for human ES cells, letting them divide without differentiating. Tests show that the hum...

Dartmouth Medical School geneticists discover new role for antisense RNA

... dark cycles reset the clocks, they found, the way turning the hands of a clock does. The clock mechanism, a biological oscillator, keeps time through the delicately balanced interplay of the Neurospora clock genes and proteins in a complex of feedback loops. "We found a long RNA antisense transcript that a...

Fetal death, miscarriage linked to genetic mutation

...believe it is a critical player in the cell cycle, turning on and off at key stages in cell division. It is also believed to be linked to two key processes that frequently malfunction when cancer begins proliferation (cell growth), and apoptosis (cell death). There is some sort of problem in the Rb pathway...

Researchers will no longer be 'snowed' in predicting future avalanches

...ion on safety issues, but some U.S. scientists are turning their focus elsewhere to studying the properties of snow stability that could lead to more accurate means of predicting avalanche events. Montana State University professor of geography Kathy Hansen has received a $160,000 National Science Foundatio...

Researcher explores tumors' survival strategy

...ss yet another protein that cuts or cleaves SPARC, turning it into a promoter. It also could be that still other proteins cleave the cell matrix, releasing its previously dormant store of growth factors and, consequently, a huge burst of factors that can induce new blood vessel formation, he said. "The scho...

Not an Ez mark The notion that a nascent set of biochemical criteria helps us understand health and disease states is not farfetched. The challenge however, is to carve away at the chemical signals, delive...

First population study of GM mosquitoes highlights difficulties facing malaria control technique

...tifies issues that need to be faced in the task of turning mosquitoes from disease carriers into disease fighters. Scientists from Imperial College London report in Science today that populations including genetically modified mosquitoes quickly lose their test marker gene when they are bred with unmodified ...

Gene appears to play important important role in controlling the growth of colorectal cancer cells

...r-suppressing gene that prevents normal cells from turning into life-threatening tumor cells. Previous research has determined that damage to p53 is fundamental to the development of a vast majority of cancers, and inactivation of the growth-controlling function of p53 is critical to the growth and spread of...

Scientist pursues role of possible new cell type

...him looking for the genes for his VENT cells. "The turning point for us will be when we know the genes of these cells; that these cells have unique genes compared to any other cells," says Dr. Sohal. He believes that gene identification likely will happen this year and says preliminary evidence indicates the...

Stanford researchers identify genes involved in tuberculosis latency

...ecreted by activated immune cells in the host - by turning on the expression of latency-inducing genes. These genes transform the physiological state, biochemical pathways and structure of the organism - changes that contribute to long-term persistence. Falling levels of nitric oxide, often a hallmark of an ...

Why we are what we eat: New links between our biology and food choices

...atty acids and cholesterol. The body's method for turning these substances into energy produces harmful free radical molecules, which can, over time, damage tissue through a process known as "oxidative' stress." Many plants provide antioxidant molecules, which can prevent this type of damage. The popularit...
