New biomarker for early cancer detection? Research reveals that 'microRNA' may fit the bill

Scientists at Fred Hutchinson Cancer Research Center have discovered that microRNAs - molecular workhorses that regulate gene expression - are released by cancer cells and circulate in the blood, which gives them the potential to become a new class of biomarkers to detect cancer at its earliest stages. Muneesh Tewari, M.D., Ph.D., and colleagues describe their findings in the July 28 issue of the Proceedings of the National Academy of Sciences.

Laboratory and mouse studies show targeted drug blocks the growth of breast cancer cells that spread to the brain

Using laboratory and mouse models of human breast cancer, researchers have found that a small molecule capable of targeting specific proteins on the surface of breast cancer cells can inhibit the growth of breast cancer cells that migrate to the brain.

Olympic doping - scientists race to stay ahead of the drug-taking and genetic manipulation

The race to ensure that scientists stop drug-taking athletes from damaging sport by using performance enhancing drugs or undergoing genetic manipulation is a constant challenge, according to a major four-decade review by three of the World's leading experts on doping in sport.

Statins reduce the risk of dementia by half

People at high risk for dementia who took cholesterol-lowering statins are half as likely to develop dementia as those who do not take statins, a new study shows.

Obesity gene makes it harder to tell if you feel full

A study involving more than 3,000 children in Britain has found those with a gene linked to obesity find it harder than others to tell when they are full.

Genome sequencing study reveals new genetic typhoid fever signatures

For the first time, next-generation DNA sequencing technologies have been turned on typhoid fever - a disease that kills 600,000 people each year. The results will help to improve diagnosis, tracking of disease spread and could help to design new strategies for vaccination.

Suprising finding on aging

Age may not be rust after all. Specific genetic instructions drive aging in worms, report researchers at the Stanford University School of Medicine. Their discovery contradicts the prevailing theory that aging is a buildup of tissue damage akin to rust, and implies science might eventually halt or even reverse the ravages of age.

New technique measures formation of clumps of proteins in protein-based pharmaceuticals

Scientists at the National Institute of Standards and Technology (NIST) have developed a technique to measure the formation of clumps of proteins in protein-based pharmaceuticals.

Advanced Cancer Therapeutics licenses technology to develop HPV vaccine

Advanced Cancer Therapeutics (ACT) has announced the signing of two new collaborative agreements that will advance development of the Company's novel human papillomavirus (HPV) vaccine program.

Column discusses HIV/AIDS risks for black women

If the popular television series "Sex and the City" "chronicl[ed] the sexually liberated adventures of four black women" instead of white women, "one of the lead characters could credibly have tested positive for" HIV, Johnathon Briggs, director of communications at the AIDS Foundation of Chicago, writes in a Chicago Tribune opinion piece.

Tobacco plant vaccine a cure for cancer?

Scientists in the U.S. say the tobacco plant could be used to "grow" key components of a cancer vaccine; they suggest that the same plant which is responsible for causing cancer may offer a way to treat the disease.

Suspect protein HMGB1 found to promote DNA repair, prevent cancer

An abundant chromosomal protein that binds to damaged DNA prevents cancer development by enhancing DNA repair, researchers at The University of Texas M. D. Anderson Cancer Center report online this week in the Proceedings of the National Academies of Science.

Genetic mechanisms at play in blood cells important in Parkinson’s disease

What does the genetics of blood cells have to do with brain cells related to Parkinson's disease? From an unusual collaboration of neurologists and a pharmacologist comes the surprising answer: Genetic mechanisms at play in blood cells also control a gene and protein that cause Parkinson's disease.

First human tests of an injectable vaccine grown in genetically engineered plants

Plants could act as safe, speedy factories for growing antibodies for personalized treatments against a common form of cancer, according to new findings from the Stanford University School of Medicine. The findings came in the first human tests of an injectable vaccine grown in genetically engineered plants.

Gene expression test could help determine who needs more aggressive treatment

Researchers from four leading cancer centers have confirmed that an analysis involving a panel of genes can be used to predict which lung cancer patients will have the worst survival. The finding could one day lead to a test that would help determine who needs more aggressive treatment.

21 new genes found for Crohn's disease

A consortium of researchers from the United States, Canada, and Europe has identified 21 new genes for Crohn's disease, a chronic disease of the large and small intestines.

Daily broccoli juice beats bladder cancer in elderly man

An elderly man in Britain believes he has beaten cancer by drinking a daily glass of broccoli juice.

Fluoroquinolones can enhance gene-silencing tool

A way to turn off one gene at a time has earned acceptance in biology laboratories over the last decade. Doctors envision the technique, called RNA interference, as a tool to treat a variety of diseases if it can be adapted to humans.

Stem cell chicken and egg debate moves to unlikely arena: the testes

Logic says it has to be the niche. As air and water preceded life, so the niche, that hospitable environment that shelters adult stem cells in many tissues and provides factors necessary to keep them young and vital, must have emerged before its stem cell dependents.

A glimpse of ancient RNA

Some bacterial cells can swim, morph into new forms and even become dangerously virulent - all without initial involvement of DNA. Yale University researchers describe Friday in the journal Science how bacteria accomplish this amazing feat - and in doing so provide a glimpse of what the earliest forms of life on Earth may have looked like.
