Your genes may hold key to how sick you get from the flu
11-03-2006 · EurekAlert!With the help of some high tech equipment, well-defined mouse models and analytical know how, researchers are trying to understand why a flu virus kills some people but not others. Studies to be presented at "Physiological Genomics and Proteomics of Lung Disease" found that a strain of mice more likely to die of influenza infection mounts a dramatically enhanced immune response in the lungs compared to a strain of mice that generally develops milder disease.

- Polymers hold promise for safer gene delivery
09-07-2007 · Massachusetts Institute of Technology (MIT)
In work that could lead to safe and effective techniques for gene therapy, MIT scientists have found a way to fine-tune the ability of biodegradable polymers to deliver genes, which could be a safer technique than using viruses to carry genes.

- Neuron cell stickiness may hold key to evolution of the human brain
11-02-2006 · EurekAlert!
The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees and other vertebrates, researchers at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute (JGI) found a strikingly high degree of genetic differences in DNA sequences that appear to regulate genes involved in nerve cell adhesion molecules.

- Bits of 'junk' RNA aid master tumor-suppressor gene
08-23-2007 · EurekAlert!
A University of Michigan study reveals that the p53 gene, a key protector mutated in half of all cancers, gets help in its vital job of stifling tumors from a trio of little-known micro RNA genes. Drugs that mimic their benefits could become important tools in cancer therapy someday.

- Genome sequencing reveals key to viable ethanol production
03-02-2007 · EurekAlert!
As the national push for alternative energy sources heats up, researchers at the University of Rochester have for the first time identified how genes responsible for biomass breakdown are turned on in a microorganism that produces valuable ethanol from materials like grass and cornstalks.Waste products such as grass clippings and wood chips -- once thought too difficult to turn into ethanol -- may soon be fodder for hungry, gene-tweaked bacteria.

- Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state
06-19-2007 · EurekAlert!
A team of Canadian scientists has identified 1,155 genes under the control of a gene called Oct4 considered to be the master regulator of the stem cell state. The study will be published in the June 20 edition of the online, open-access journal PLoS ONE.

- Avian influenza survivors' antibodies effective at neutralising H5N1 strain
05-28-2007 · EurekAlert!
Adults who have recovered from the potentially deadly H5N1 strain of avian influenza may hold the key to future treatments for the virus, according to an international team of researchers. In a study published today in the open access journal PLoS Medicine, the researchers have shown how specific antibodies taken from avian flu survivors in Vietnam can be reproduced in the laboratory and prove effective at neutralising the virus in culture vitro and in mice.

- 10 Top Australian Scientists Predict Major Medical Advances
10-10-2006 · ScienceDaily
Australians will soon be able to find out how good their genes are at fighting disease, what risks they are susceptible to and what they can do to prevent ill-health. And by the turn of the century it will be commonplace to have a bad combination of genes repaired to avoid disease. A new report compiled by Research Australia with 10 top Australian medical researchers predicts individual gene profiling will revolutionize health care within a decade.

- Fighting like a girl or boy determined by gene in fruit flies
11-19-2006 · EurekAlert!
Fighting like a girl or fighting like a boy is hardwired into fruit fly neurons, according to a study in the November 19 Nature Neuroscience advance online publication by a research team from Harvard Medical School and the Institute of Molecular Pathology in Vienna. The results confirm that a gene known as "fruitless" is a key factor underlying sexual differences in behavior.
