Nanoparticles yield delivery tools for therapeutic nucleic acids

Cancer researchers hold great hope that nucleic acid-based therapeutics, such as anticancer genes, antisense oligonucleotides, and small interfering RNA (siRNA) molecules, will prove to be powerful antitumor agents.

Fibrinogen molecule structure acts as a molecular spring

Researchers at the University of Pennsylvania School of Medicine and the School of Arts and Sciences have shown that a well-known protein structure acts as a molecular spring, explaining one way that clots may stretch and bend under such physical stresses as blood flow.

Variations in SORL1 gene may factor in development of Alzheimer's disease

Variations in a gene known as SORL1 may be a factor in the development of late onset Alzheimer's disease, an international team of researchers has discovered. The genetic clue, which could lead to a better understanding of one cause of Alzheimer's, is reported in Nature Genetics online, and was supported in part by the National Institutes of Health (NIH).

Stem cell research discovery could mean 'big things' for cancer

A new discovery in stem cell research may mean big things for cancer patients in the future. Gary Van Zant, Ph.D., and a research team at the University of Kentucky published their findings in Nature Genetics.

Men with short telomeres may have a greater risk for heart disease

Men with short telomeres - repetitive strips of DNA that cap the ends of chromosomes - may have a higher risk of developing coronary heart disease than those with long telomeres, according to an Article in this week's issue of The Lancet.

New treatment technique for decontaminating flood water

Engineers have developed a system that uses a simple water purification technique that can eliminate 100 percent of the microbes in New Orleans water samples left from Hurricane Katrina. The technique makes use of specialized resins, copper and hydrogen peroxide to purify tainted water.

Enzyme PMR1 reveals kind side

New research shows that a recently discovered enzyme that destroys the messenger RNA (mRNA) for some proteins can also help to protect the mRNA during times of stress. The response might help cancer cells survive chemotherapy and radiation therapy.

Micro molecules identify pancreatic cancer

A pattern of micro molecules can distinguish pancreatic cancer from normal and benign pancreatic tissue, new research suggests.

New embryonic cell discovery

Cambridge scientists have discovered the stage at which some of the cells of a fertilised mammalian egg are fated to develop into stem cells and why this occurs.

Fat-hormone leptin may enhance the growth of colonic cancers

Tests on three human colon cancer cell lines showed that the fat-hormone 'leptin' may enhance the growth of colonic cancers. This finding could show why obese people are at increased risk of colon cancer.

Stem cells derived from human amniotic fluid appear to offer many of the benefits of embryonic stem cells

...including the ability to grow into brain, muscle, bone and other tissues -- according to a study published in the Jan. 7 online edition on the journal Nature Biotechnology, the Washington Post reports.

Several specific genetic alterations associated with development of smoking-related cancers

Preliminary research indicates that several specific genetic alterations are associated with the development of smoking-related head and neck skin cancers, according to a report in the January 10 issue of JAMA: The Journal of the American Medical Association.

New hope for Krabbe disease sufferers

By all expectations, it shouldn't have worked as well as it did. A combination of bone marrow transplantation and gene therapy greatly lengthened the lives of laboratory mice doomed by a rapidly progressing, fatal neurodegenerative disorder also found in people.

House to vote on expansion of funding for human embryonic stem cell research

The House later this week plans to vote on a measure (HR 3, S 5) -- called the Stem Cell Research Enhancement Act of 2007 -- that would expand federal funding for human embryonic stem cell research, CQ HealthBeat reports.

Study shows why the body's immune system doesn't attack tissues in the small intestine

Answering one of the oldest questions in human physiology, researchers at Dana-Farber Cancer Institute have discovered why the body's immune system - perpetually on guard against foreign microbes like bacteria - doesn't attack tissues in the small intestine that harbor millions of bacteria cells.
