Harmful chemicals may reprogram gene response to estrogen

... cancers of the uterus, breast and prostate." The finding should alert doctors to ask more questions about a patient's early-life exposures to chemicals and other harmful agents in order to better predict that person's cancer risk. "Most people with a family history for a particular disease are concerned a...

Brain-mapping technique aids understanding of sleep, wakefulness

...r completely awake or completely asleep." Another finding from the Neuron study may help explain why once you're awake and moving around, you tend to stay awake, a process called activity induced consolidation of wakefulness. Some neurons in the basal forebrain produce the chemical acetylcholine. These cel...

Protein That Promotes Survival Of Stem Cells Might Be Key To Poor Leukemia Prognosis

...s for them. This fits into the St. Jude mission of finding cures for catastrophic diseases of childhood, such as leukemia, in order to save lives." The importance of Mcl-1 lies in the differing roles it plays in health and disease. "On one hand, this protein keeps HSCs and progenitor cells alive and multip...

Canadian youth 4th highest in international obesity study

...ing overweight, he adds. Along with this alarming finding is one that runs contrary to what the research team expected. Surprisingly, as consumption of candy and chocolate increased, the likelihood of being overweight decreased. "This does not mean that eating sweets in large quantities is recommended for ...

Discovery may lead to better Candidiasis drug

...of a specific target for histatin," she said. "The finding paves the way for eventually developing a better therapeutic drug for candidiasis." Results of the research were presented today (March 11, 2005) at the International Association on Dental Research General Session being held in Baltimore. Candidias...

Emergence of cancer as major cause of childhood death in developing countries is not being adequately addressed

...ernationally recognized for its pioneering work in finding cures and saving children with cancer and other catastrophic diseases. Founded by late entertainer Danny Thomas and based in Memphis, Tenn., St. Jude freely shares its discoveries with scientific and medical communities around the world. No family ev...

Study reveals new technique for fingerprinting environmental samples

...e actual identities of the resident microbes. This finding is crucial for studies of microbes in the wild since the sheer number of different organisms present in nearly all environments makes it a daunting task to sequence the multitude of organisms one at a time. With the EGT approach, an abbreviated seque...

Leprosy microbes lead scientists to immune discovery

...nse by two separate armies of defensive cells. The finding helps explain why, when threatened by microbes like the leprosy bug, this initial defense sometimes succeeds in limiting the damage, but in other cases yields to a dangerous, spreading infection. Led by Stephan R. Krutzik of UCLA, a team of scientis...

Different microarray systems more alike than previously thought

... results reported properly." The impact of such a finding is not insignificant, experts say, because these systems may ultimately allow scientists to uncover critical differences between, say, healthy and cancerous tissue. Unless laboratories can rely on each others' results, such findings would not have mu...

New understanding of DNA repair may pave way to cancer treatments

...grammed cell death. These studies evolved from the finding that ATF2 has an important role in the development...d function for the same protein," said Ronai. The finding of ATF2's novel function in DNA repair was serendipitous. As Shoichi Takahashi, a postgraduate resea...

A puzzle piece found in unraveling the wiring of the brain

...n Houston have unraveled a piece of that puzzle by finding a gene that plays a key role in brain wiring. A report on their work appears today in the journal Neuron. "We were surprised to find an exocyst mutant having such specific defects," said Bellen, professor of molecular and human genetics at BCM. "The...

Brain-injury rehabilitation depends on acetylcholine circuitry

...Neural repair Group at UCSD have discovered. Their finding in rats could help enhance rehabilitation to recov...linergic system." The researchers said that their finding that the cholinergic system is involved in brain recovery is particularly intriguing in light of the...

NIH Researchers Discover How Insulin Allows Entry of Glucose Into Cells

...Diabetes and Digestive and Kidney Diseases. “This finding provides useful information for understanding disorders in which cells have difficulty using insulin, such as insulin resistance and type 2 diabetes,?said NICHD Director Duane Alexander, M.D. Glucose, a simple sugar, is a nutrient that cells need to...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...es in the front of the foot and along the edges--a finding consistent with the notion that elephants are sensing seismic signals when they press their feet on the ground. O'Connell-Rodwell also is applying her insights in animal seismicity to the problem of hearing loss in humans. It turns out that people w...

Cooperation is key—a new way of looking at MicroRNA and how it controls gene expression

...nces complementary to the microRNA's sequence. But finding the targets of these microRNA proved difficult, an... in 2001, many scientists thought that the task of finding the mRNA to which the microRNA bound would be relatively straightforward. After all, a short stretch...

Anammox bacteria produce nitrogen gas in oceans' snackbar

...(much better than denitrifying bacteria). This new finding even increases the importance of anammox bacteria in the ocean. New species The anammox bacteria discovered in the Atlantic Ocean are closely related to the bacterial species Scalindua sorokinii, which was recently discovered in the Black Sea (Kuype...

Insight into DNA's 'weakest links' may yield clues to cancer biology

Decoding the logic of olfaction

...imilar patterns of activation in the cortex. "This finding gives a hint that there is some logic to the way that information is being mapped onto the cortex," said Buck. "We don't know what that logic is, but it seems as if it has something to do with the molecular features of the odorant." The researchers ...
