Increased SIRT1 protein can delay delay aging, extend lifespan

Researchers watched two groups of mice, both nearing the end of a two-day fast. One group was quietly huddled together, but the other group was active and alert. The difference? The second set of mice had been engineered so their brains produced more SIRT1, a protein known to play a role in aging and longevity.

New study reveals potential role of TGF-β1 in kidney disease

Fibrosis in the kidney is one of the key causes of progressive renal failure. High levels of the inflammatory molecule TGF-β1 in the kidney tubules due to tissue damage can cause fibrosis as well as nephron degeneration, resulting in loss of kidney function. To clarify the mechanisms regulating TGF-β1-mediated renal fibrosis, Koesters et al expressed high levels of TGF-β1 in renal tubules of mice. Nephron degeneration in this system was mediated by decomposition of the tubular cells. These data suggest that TGF-β1 may play a novel role in cell death of renal cells, thus contributing to renal fibrosis.

Scientists develop laser activated carbon nanoparticles for drug, gene delivery

Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells.Carbon nanoparticles activated by bursts of laser light trigger the tiny blasts, which open holes in cell membranes just long enough to admit therapeutic agents contained in the surrounding fluid. By adjusting laser exposure, the researchers administered a small-molecule marker compound to 90 percent of targeted cells - while keeping more than 90 percent of the cells alive.

Scientists unveil new biomarkers for stroke, coronary heart disease

Analysis of blood protein data from the Women's Health Initiative cohorts has revealed new biomarkers for stroke and coronary heart disease (CHD). Research published in BioMed Central's open access journal Genome Medicine found that beta-2 microglobulin (B2M) levels were significantly elevated in postmenopausal women with CHD, and insulin-like growth factor binding protein 4 (IGFBP4) was strongly associated with stroke.

Research on method to open blood-brain barrier for safe cancer drug delivery

One of the human body's most powerful defensive tools, the blood-brain barrier is a chemical labyrinth that prevents toxins and viruses in the bloodstream from reaching the brain. This foolproof security system, however, limits the ability of physicians to deliver drugs directly to the brain, making it difficult to treat brain tumors. Researchers at Rensselaer Polytechnic Institute are endeavoring to solve this problem by investigating new methods for bypassing the blood-brain barrier and combating the spread of brain cancer.

Scientists develop novel chemotherapeutic method for anticancer drug delivery

Combining nature and Greek mythology, researchers at the Technion-Israel Institute of Technology have developed a tiny "Trojan Horse" system for delivering cancer-fighting drugs. With this system, the drugs are delivered only once they are inside the cancerous cells, so there is no damage to the healthy cells in the surrounding area.

Attaching transferrin to nanoparticle surface can kill cancer cells

A normally benign protein found in the human body appears to be able - when paired with nanoparticles - to zero in on and kill certain cancer cells, without having to also load those particles with chemotherapy drugs.The finding could lead to a new strategy for targeted cancer therapies, according to the University of North Carolina at Chapel Hill scientists who made the discovery.

Progenra receives Official Notice of Allowance for screening platform

Progenra, Inc., announced today their receipt of an Official Notice of Allowance, dated June 15, 2010, of U.S. Patent Application No. 11/156,707, "Diagnostic and Screening Methods and Kits Associated with Proteolytic Activity." IP protection of this technology was also recently granted by the European Union. This technology will enable faster drug discovery by improving the ability to identify more selective drugs that modulate the handling of proteins associated with various disease states.

Study on treatment needs of prostate cancer patients with low level PSA

Controversy has long existed over the benefit of the prostate specific antigen (PSA) test used to screen for the presence of prostate cancer, and there has been little study to document the risk profile of men who have a PSA level at or below what is considered 'normal.' New research published in the latest edition of Archives of Internal Medicine (Vol. 170, No. 14) by a team of investigators at The Cancer Institute of New Jersey (CINJ), further explores this population. The findings show that most men with prostate cancer who tested below the normal PSA level and had low-risk disease nevertheless underwent aggressive treatment. CINJ is a Center of Excellence of UMDNJ-Robert Wood Johnson Medical School.
