Cell signaling is vital for cells to communicate and coordinate their activities, not just in the human body, but in all organisms. There are thousands of signaling pathways, ranging from protein homeostasis to carcinogenesis and biofilm formation.

Researchers discover new cause of hydrocephalus

Researchers at the University of Iowa have discovered a new cause of hydrocephalus, a devastating neurological disorder that affects between one and three of every 1,000 babies born. Working in mice, the researchers identified a cell signaling defect, which disrupts immature brain cells involved in normal brain development.

Biomolecular imaging: an interview with Professor Roger Reddel

The reason Children’s Medical Research Institute (CMRI) exists is to find ways to treat or prevent childhood disease. Our research programs are focussed on the areas of cancer cell growth, nerve cell signalling, embryology and gene therapy. These four programs have a shared aim of translating novel findings into new treatments for the benefit of families everywhere.

Tug of war between Hsp70 and 90 determines how much the body makes of superoxide

Two proteins are in a tug of war that determines how much the body makes of superoxide, a highly reactive and potentially destructive product of oxygen that's dramatically elevated in cardiovascular disease, researchers report.

Scientists find new way to unlock cells' destinies

Scientists have discovered that breaking a biological signaling system in an embryo allows them to change the destiny of a cell.

Dysfunction in SRGAP3 protein causes developmental brain disorders

A new research discovery has the potential to revolutionize the biological understanding of some childhood psychiatric disorders. Specifically, scientists have found that when a single protein involved in brain development, called "SRGAP3," is malformed, it causes problems in the brain functioning of mice that cause symptoms that are similar to some mental health and neurological disorders in children.

VEGF produced by NPCs plays a strong role in influencing microglial behavior

The brain's key "breeder" cells, it turns out, do more than that. They secrete substances that boost the numbers and strength of critical brain-based immune cells believed to play a vital role in brain health. This finding adds a new dimension to our understanding of how resident stem cells and stem cell transplants may improve brain function.

High-fat Western diet could lead to development of atherosclerosis

Columbia University Medical Center (CUMC) researchers have found that a diet high in saturated fat raises levels of endothelial lipase (EL), an enzyme associated with the development of atherosclerosis, and, conversely, that a diet high in omega-3 polyunsaturated fat lowers levels of this enzyme.

PUFA levels reduced in schizophrenia patients

Results from a systematic review and meta-analysis show that erythrocyte membrane concentrations of certain polyunsaturated fatty acids are reduced in the brains of people with schizophrenia.

Synta announces results from ganetespib Phase 2b trial on NSCLC

Synta Pharmaceuticals Corp. today announced results from an interim analysis of the Phase 2b portion of the GALAXY trial, a global, randomized, multi-center Phase 2b/3 study designed to evaluate the efficacy and safety of the Company's lead Hsp90 inhibitor, ganetespib, as second-line treatment for advanced non-small cell lung cancer (NSCLC).

APS conference to explore potential mechanisms behind health benefits of exercise

The effects of physical inactivity are, literally, hazardous to your health. Although the detrimental effects of being inactive are generally thought to be associated with childhood obesity and Type 2 diabetes, they have a significant impact on other illnesses. Physical inactivity contributed at least 25 percent to the prevalence of hip fractures, osteoporosis, coronary heart disease, and colon cancer according to recent data released by the U.S. Department of Health and Human Services.

UH lecture to explore hormones in health and disease

While estrogen is essential for many of the body's normal processes in both men and women, it also plays a role in diseases such as breast, ovarian and prostate cancer. The impact of this hormone on such diseases will be addressed during a lecture Sept. 25 at the University of Houston (UH).

PD0325901 drug may hold potential to prevent neurofibromatosis 1 in children

A drug originally developed to stop cancerous tumors may hold the potential to prevent abnormal brain cell growth and learning disabilities in some children, if they can be diagnosed early enough, a new animal study suggests.

SPR microscopy examines binding kinetics of membrane proteins

Proteins adorning the surfaces of human cells perform an array of essential functions, including cell signaling, communication and the transport of vital substances into and out of cells. They are critical targets for drug delivery and many proteins are now being identified as disease biomarkers - early warning beacons announcing the pre-symptomatic presence of cancers and other diseases.
