Researchers uncover new mechanism of tumor suppressor

...o regulate gene expression programs that allow for appropriate responses to DNA damage in normal cells. When the process breaks down, such damage and other acute stresses are thought to lead to cancer. The first study, Molecular mechanism of histone H3K4me3 recognition by plant homeodomain of ING2, was conducte...

Case Western Reserve University researchers find protein associated with brain cell death

..., the researchers found that the microglia had the appropriate immune response that the plaque was harmful, but then the protein Vav was found to be a component in oxidative damage since elimination of the protein resulted in reduced free radical production. Wilkinson said by understanding this biological comp...

How healthy is that marsh? Biologists count parasites

...sing, it could indicate that its hosts are lacking appropriate habitats. "The trematode information provides a novel way to see what we need to alter to improve habitats," Kuris said. The feasibility of the snail-as-data-logger idea was established at a case-study site at the Carpinteria salt marsh in Santa Ba...

Wild vs. lab rodent comparison supports hygiene hypothesis

... and allergic-like immune responses that represent appropriate responses to unknown factors in their environment," he said. Although this study suggests that the environment plays an important role in how the immune systems in animals develop, genetics is likely to be involved as well, Parker said. He now is pl...

New roles for growth factors: Enticing nerve cells to muscles

...ly when newborn neurons extend axons to "wire" the appropriate muscle fiber. The wiring process is highly orchestrated –each motor neuron has already pledged allegiance to a particular muscle fiber before it reaches out to connect with its predetermined partner. But until now, scientists could only speculate ho...

"It seems only appropriate that while we are all concerned about loss of biodiversity in the rainforests and coral reefs that we at least start to learn what is in our own backyards. Tennessee and neighboring states contain the world's richest diversity of freshwater mussels....

3-D model reveals secrets of metastasis

...ually use three-dimensional assays, accompanied by appropriate computational models such as that also recently published by Zaman (in Biophysical Journal in 2005), to determine how drugs affect metastasis. But technology must improve before more complicated 3D studies are attempted. For his 3D work Zaman worke...

Hopkins scientists show hallucinogen in mushrooms creates universal 'mystical' experience

...edfollowup survey were used to rate experiences at appropriate times in the study. They included those that differentiate effects of psychoactive drugs, that detect altered states of consciousness, that rate mystical experiences and assess changes in outlook. The study, Griffiths adds, has advanced understa...

In drug design, a loose fit may be best bet

...de of biochemical events leading to the unique and appropriate cellular response to that hormone. "GPCRs are the targets of roughly a third of medicines sold today, so if this finding for TRH holds for other GPCR targets, it could have significant implications for drug development," says Marvin C. Gershengorn, ...

Leptin found to control appetite and limb development in frogs

...he form of body fat - to start metamorphosis at an appropriate time. Finding leptin in the Xenopus genome was no small feat. The sequence for the "obese" gene that makes leptin is quite different between frogs and humans, so Denver's lab had some puzzles to solve to successfully clone the frog gene. But once th...

Report focuses on the role good microbes play in future medicine

...posure to commensal organisms is necessary for the appropriate development of both the innate and acquired immune systems. Once established, probiotic organisms interact with these immune defenses, possibly changing the nature of the immune response to other antigens, including commensal and pathogenic organism...

Large-scale genomics project will hunt genes behind common childhood diseases

...agnostic knowledge to guide physicians to the most appropriate therapies. In addition, we plan to form strategic partnerships with biopharmaceutical companies to develop novel therapeutics," said Dr. Hakonarson. Tailoring treatments to a patient's genetic profile represents an era of personalized medicine stil...

New strategy developed to combat West Nile Virus

But in almost all cases, the amplification of West Nile Virus will start with mosquitoes that carry the disease mingling with birds that are good carriers. "How fast ...

"The harmonization of such environmental standards across the ASEAN region is sure to provide a wide range of benefits. To give a simple example, once a standard was agreed on how to measure a person's blood pres...

New study calculates millions of years saved in lives of AIDS patients

Vermund, MD, PhD, of Vanderbilt University observed that the benefits of HAART suggested by this study are greater than previously thought and may become still greater if certain barri...

Where we change our mind

In their experiments, the researchers first taught volunteer subjects the layout of a computer-generated 3D "wire-frame" maze. Then, while the subj...

Embryo tests give parents the choice

"There are more than 1000 genetic tests currently available and there is no reason why any of these couldn't be used for PDG," she ...
