Nanoparticle-delivered suicide gene therapy effectively reduces ovarian tumor burden in mice

Nanoparticle delivery of diphtheria toxin-encoding DNA that expresses selectively in ovarian cancer cells reduced the burden of ovarian tumors in mice, and researchers expect that this therapy could be tested in humans with advanced ovarian cancer within 18 to 24 months, according to a report in Cancer Research. If additional tests are successful, these finding could lead to a new treatment for ovarian cancer, which now causes more than 15,000 deaths each year in the United States. Because it is usually diagnosed at a relatively late stage, ovarian cancer is one of the most deadly forms of the disease.

Molecularly targeted nanocarriers deliver the cytolytic peptide melittin specifically to tumor cells in mice, reducing tumor growth

When bees sting, they pump into their victims a peptide toxin called melittin that destroys cell membranes. Now, by encapsulating this extremely potent molecule within a nanoparticle, researchers at the Washington University School of Medicine in St. Louis have created a potential new type of anticancer therapy with the potential to target a wide range of tumors. This work was reported in the Journal of Clinical Investigation.

CLU and PICALM genes associated with Alzheimer's disease

British scientists have discovered two new genes associated with Alzheimer's disease, while French colleagues uncovered a third. The results, from the largest ever Alzheimer's genome-wide association study (GWAS) involving 16,000 individuals, are published in Nature Genetics. They are the first new genes found to be associated with the common form of Alzheimer's disease since 1993.

IRS1 gene could lead to better treatment of type 2 diabetes

A breakthrough by an international team of researchers in Canada, France, the UK and Denmark has uncovered a new gene that could lead to better treatment of type 2 diabetes, as well as a better understanding of how this widespread disease develops.

Cancer drug could restore memory deficits in Alzheimer's patients

A drug now used to treat cancer may also be able to restore memory deficits in patients with Alzheimer's disease, according to a new study conducted by scientists at Columbia University Medical Center, which appeared in the September issue of The Journal of Alzheimer's Disease: Volume 18:1.

Texas Senators higlight CMS about the delay in opening many local dialysis facilities

As Congress prepares to reconvene next week following an August recess period filled with wide-ranging local discussion of health care reform, the Texas kidney community expressed hope that the momentum and public desire for health care reform in Washington can help drive momentum and discussion in Texas about the vital need to open 38 end stage renal disease (ESRD) centers still sitting idle, which, if opened, will dramatically expand access to quality dialysis care and create good-paying local jobs.

Brain protein srGAP2 capable of forming filopodia

When the process goes awry, neurodevelopmental disorders such as mental retardation, dyslexia or autism may result. Researchers at the University of North Carolina at Chapel Hill School of Medicine have now discovered that establishing the neural wiring necessary to function normally depends on the ability of neurons to make finger-like projections of their membrane called filopodia.

Researchers study tumor diversity to improve breast cancer treatment

One person's breast cancer is not the same as another person's, because the gene mutations differ in each tumor. That makes it difficult to match the best therapy with the individual patient.

New approach for understanding how drug resistance occurs in leukemia

UCSF researchers have developed a new approach to identify specific genes that influence how cancer cells respond to drugs and how they become resistant. This strategy, which involves producing diverse genetic mutations that result in leukemia and associating specific mutations with treatment outcomes, will enable researchers to better understand how drug resistance occurs in leukemia and other cancers, and has important long-term implications for the development of more effective therapies.

New role discovered for sphingosine-1-phosphate

Virginia Commonwealth University School of Medicine researchers have discovered a new role for the bioactive lipid messenger, sphingosine-1-phosphate, or S1P, that is abundant in our blood - a finding that could lead to a new generation of drugs to fight cancer and inflammatory disease.

nSR100 protein plays a key role in neuron development

Researchers at the University of Toronto have identified a protein which plays a key role in the development of neurons, which could enhance our understanding of how the brain works, and how diseases such as Alzheimer's occur.

FOXO3a protein stimulates cancer development

In a biological rendition of fiction's Strange Case of Dr. Jekyll and Mr. Hyde, researchers from the Mayo Clinic campus in Florida and Harvard Medical School have found that a protein thought to protect against cancer development can actually spur the spread of tumors.

NCI renews SPORE grant for the diagnosis and treatment of ovarian cancer

National Cancer Institute (NCI) has renewed a $11.5 million Specialized Program of Research Excellence (SPORE) grant in prevention, diagnosis and treatment of ovarian cancer, which supports multidisciplinary research at Fox Chase Cancer Center and the University of Pennsylvania. First approved in 1999, this marks the third five-year term for the Fox Chase-Penn Ovarian SPORE.

Genetic cause of progressive hearing loss discovered

A team led by scientists from The Scripps Research Institute has discovered a genetic cause of progressive hearing loss. The findings will help scientists better understand the nature of age-related decline in hearing and may lead to new therapies to prevent or treat the condition.
