Scientists discover link between mutations in INPP5E gene and ciliopathies

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, have discovered a connection between mutations in the INPP5E gene and ciliopathies. Their findings, which may lead to new therapies for these diseases, will appear in the online edition of Nature Genetics on August 9.

Changes in mtDNA can cause premature ageing

The normal ageing process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients. Researchers at the Swedish medical university Karolinska Institutet have now shown how certain proteins that are synthesised in the cellular mitochondria - popularly known as the cells' power plants - become unstable and disintegrate, which in turn can impair cell respiration and cause premature ageing.

Scientists find key to strengthening immune response to chronic infection

A team of researchers from The Wistar Institute has identified a protein that could serve as a target for reprogramming immune system cells exhausted by exposure to chronic viral infection into more effective "soldiers" against certain viruses like HIV, hepatitis C, and hepatitis B, as well as some cancers, such as melanoma.

Proteomics helps find key to keeping cells in shape

Yale University researchers have discovered how a protein within most cell membranes helps maintain normal cell size, a breakthrough in basic biology that has implications for a variety of diseases such as sickle cell anemia and disorders of the nervous system.

Bellicum Pharmaceuticals starts phase I/II trial of novel advanced prostate cancer vaccine

Bellicum Pharmaceuticals, Inc. today announced dosing of the first patient in a Phase I/II clinical trial of BP-GMAX-CD1, a novel pharmacologically regulated dendritic cell vaccine for the treatment of prostate cancer. The disease-specific trial is being conducted under a Bellicum Investigational New Drug application allowed by the FDA in 2008. The company anticipates reporting initial results of the study in 2010.

Genetic profiling of tumors could have 'immediate impact' on treating cancer

New work by MIT cancer biologists shows that the interplay between two key genes that are often defective in tumors determines how cancer cells respond to chemotherapy.

Discovery of cells responsible for bladder cancer spread

Johns Hopkins scientists have tracked down a powerful set of cells in bladder tumors that seem to be primarily responsible for the cancer's growth and spread using a technique that takes advantage of similarities between tumor and organ growth. The findings, reported in the July Stem Cells, could help scientists develop new ways of finding and attacking similar cells in other types of cancer.

Protein unfolding key to understanding blood clot mechanics

Fibrin, the chief ingredient of blood clots, is a remarkably versatile polymer. On one hand, it forms a network of fibers -- a blood clot -- that stems the loss of blood at an injury site while remaining pliable and flexible. On the other hand, fibrin provides a scaffold for thrombi, clots that block blood vessels and cause tissue damage, leading to myocardial infarction, ischemic stroke, and other cardiovascular diseases. How does fibrin manage to be so strong and yet so extensible under the stresses of healing and blood flow?

Discovery of new gene mutations linked to leukemia

Decoding the complete DNA of cancer patients is giving scientists at Washington University School of Medicine in St. Louis a clearer picture of the complexity of the disease and allowing them to see intriguing and unexpected genetic relationships among patients.

Research looks at cellular stress response to low oxygen

Gary Chiang, Ph.D., and colleagues at Burnham Institute for Medical Research (Burnham) have elucidated how the stability of the REDD1 protein is regulated. The REDD1 protein is a critical inhibitor of the mTOR signaling pathway, which controls cell growth and proliferation.
