Mental Decline Thwarted in Aging Rats
Scientists have discovered a compound that restores the capacity to form new memories in aging rats, likely by improving the survival of newborn neurons in the brain's memory hub. The research, funded in part by the National Institutes of Health, has turned up clues to a neuroprotective mechanism that could lead to a treatment for Alzheimer's disease.
Gene Linked to Alzheimers Disease Plays Key Role in Cell Survival
Scientists have discovered that a gene linked to Alzheimer's disease may play a beneficial role in cell survival by enabling neurons to clear away toxic proteins. A study funded by the National Institute on Aging (NIA), part of the National Institutes of Health, shows the presenilin 1 (PS1) gene is essential to the function of lysosomes, the cell component that digests and recycles unwanted proteins. However, mutations in the PS1 gene -- a known risk factor for a rare, early onset form of Alz...
Scientists Identify Two Gene Variants Associated with Alzheimers Risk
In the largest genome-wide association study (GWAS) reported to date involving Alzheimer's disease, scientists have identified two new possible genetic risk factors for late-onset Alzheimer's, the most common form of the disease. The study, which pooled DNA samples from a number of European and U.S. groups, not only associated variations in the sequence of the CLU and PICALM genes with increased risk, but also found another 13 gene variants that merit further investigation, according to findi...
Increased Risk of Stroke Linked to Genetic Variants
Scientists have identified a previously unknown connection between two genetic variants and an increased risk of stroke, providing strong evidence for the existence of specific genes that help explain the genetic component of stroke. The research was funded by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health and by several other NIH institutes and centers.
Scientists Report Important Step in Biomarker Testing for Alzheimer
Scientists have made a significant step forward in developing a test to help diagnose the early stages of Alzheimer's disease sooner and more accurately by measuring two biomarkers -- tau and beta-amyloid proteins -- in cerebrospinal fluid. In a new report, researchers from the Alzheimer's Disease Neuroimaging Initiative (ADNI) not only confirmed that certain changes in biomarker levels in cerebrospinal fluid may signal the onset of mild Alzheimer's, but also established a method and standard...
Researchers Develop DNA Patch For Canine Form of Muscular Dystrophy
Using a novel genetic technology that covers up genetic errors, researchers funded in part by the National Institutes of Health have developed a successful treatment for dogs with the canine version of Duchenne muscular dystrophy, a paralyzing, and ultimately fatal, muscle disease.
