Turning a cellular sentinel into a cancer killer

...th the adaptability of cancers. "For any therapies based on these findings, you would have to imagine that sooner or later, resistance would develop," said Lowe. "And I think the challenge—which is true for any therapy where you can get resistance—is to come up with combination treatments that take out eno...

Genomics throws species definition in question for microbes

...ns of describing microorganisms, so the system was based on measurable and observable characteristics of the organisms, not genetic traits. In the late 20th century, molecular biology uncovered the genetic relationships between microorganisms, and some of the secrets of microbes that had yet to be cult...

Minuscule molecules pack a powerful punch

..." The study emphasizes the value of the ES cell based knockout technology, currently being pursued on a large scale through the KOMP and EUCOMM programmes at the Wellcome Trust Sanger Institute. This success illustrates the power of the mouse to reveal function and indicates a wider role for microRNAs i...

New test helps identify hepatitis C patients at high risk of developing cirrhosis

Scientists identify a candidate gene for osteoporosis

... then we may be able to develop therapies that are based on inhibiting the function of the DARC gene," explains Dr. Subburaman Mohan, Ph.D., a Senior Scientist at the Loma Linda VA Medical Center and a Professor of Medicine and Biochemistry at Loma Linda University. "We will also be able to develop genet...

Biologists call for better choice of model organisms in 'evo-devo'

... a more judicious approach to selecting organisms, based on the evo-devo themes that the organism can shed light on. "It is fair to say that, since its inception, some workers feel that evo-devo hasn’t quite lived up to its early expectations," said Dr Jenner. "Partly this is because too much was exp...

Music genes and musical geniuses

...t medical problems as well as potential treatments based on listening and producing music? The idea of combining music and genetics in a single event grew up within the European Genetics Foundation, on initiative of Professor Giovanni Romeo, medical geneticist at the University of Bologna: “We realized ...

New approach could lower antibiotic requirements by 50 times

... be reduced by up to 50 times using a new approach based on bacteriophages. Steven Hagens, previously at the University of Vienna, told Chemistry & Industry, the magazine of the SCI, that certain bacteriophages, a type of virus that infects bacteria, can boost the effectiveness of antibiotics gentamic...

Investment level in HIV prevention programs related to HIV incidence in the United States

...s saved." Holtgrave noted that the analysis was based on historical data and is not a prospective trial of prevention effectiveness. Therefore, it is subject to methodological limitations. Nevertheless, he said it provides substantial indications of a strong relationship between the amount of national i...

Research project tackles 'regeneration' gap

...el, Fla., and from the Thomas H. Maren Foundation, based in Gainesville ?and from the UF Office of Research. Initial funding will help provide fellowships for young scientists who will bridge the gaps between the different labs and investigators involved in regeneration research. "The fellows will be t...

Widely used hepatitis B drug spurs HIV drug resistance

...ve any significant effects on HIV, about they were based on older tests that could not quantify the effects of HIV on individual immune cells or detect mutations. Thio believed that the recent patient cases called for a more thorough investigation with more advanced techniques. She and her team combine...

Light wine intake is associated with longer life expectancy in men

...the men throughout the 40-year study was six grams based on any alcohol intake of more than zero and up to 20 grams. The long-term average intake of six grams of alcohol is equal to one four-ounce beer, one two-ounce glass of wine or one one-ounce glass of spirits, daily. When the researchers looked in...

It's in your head: The brain's own globin defends you from shock and stroke

...eration of treatments for shock or stroke could be based on a protein that is already in our heads ?neuroglobin. In a review article to be published in the November issue of The FASEB Journal, scientists from University of Rome describe this protein, which may be the key to unlocking new therapies to minim...

St. Jude announces breakthrough in eye cancer treatment

...t of Developmental Neurobiology. The treatment is based on a discovery by Dyer's laboratory that overturned a widely held belief about the process of apoptosis (cell suicide) in retinoblastoma. Apoptosis is the way the body rids itself of abnormal cells that might become cancerous or cause other problems....

Global map shows new patterns of extinction risk

These decisions have typically been based on the assumption that investing in an area known to have a high concentration of endangered birds, for example, will mean that large numbers of endangered mammal and amphibian species will also be protected. The new study shows that basing conservat...

By 2048 all current fish, seafood species projected to collapse

...have to use models to understand this trend; it is based on all the available data." Researchers also determined that the problem is much greater than losing a key source of food. Damage to the oceans impact not only fisheries, but the ocean ecosystem's overall productivity and stability. Specific servic...

Antibiotic inhibits cancer gene activity

... The researchers developed a new screening system, based on a naturally fluorescent protein called luciferase, to identify small molecules that inhibit proteins that turn genes on and off. Using this system, they identified an antibiotic, siomycin A, that specifically targets FoxM1 without affecting other ...
