Basic Yellow 1 dye extends lifespan in healthy nematodes, slows Alzheimer's disease-like pathology in worms

Basic Yellow 1, a dye used in neuroscience laboratories around the world to detect damaged protein in Alzheimer's disease, is a wonder drug for nematode worms. In a study appearing in the March 30, online edition of Nature, the dye, also known as Thioflavin T, (ThT) extended lifespan in healthy nematode worms by more than 50 percent and slowed the disease process in worms bred to mimic aspects of Alzheimer's.

Protein aggregation plays a significant role in cancer

Protein aggregation, generally associated with Alzheimer's and mad cow disease, turns out to play a significant role in cancer. In a paper published in Nature Chemical Biology, Frederic Rousseau and Joost Schymkowitz of VIB, K.U.Leuven and Vrije Universiteit Brussel describe that certain mutations of p53, an important tumor suppressor, cause the protein to misfold in a way that the proteins start to aggregate.

Scientists discover fundamental mechanism behind toxic protein aggregation in neurodegenerative diseases

Protein aggregation underlies several neurodegenerative diseases such as Alzheimer's, Huntington's chorea or Parkinson's. Scientists at the Max Planck Institute of Biochemistry (MPIB) in Martinsried near Munich, Germany, now discovered a fundamental mechanism which explains how toxic protein aggregation occurs and why it leads to a widespread impairment of essential cellular functions.

Over expression of transcription factor improves neurological function in HD transgenic mice models

Over expressing a transcription factor that promotes the increase in number of mitochondria greatly improves the neurological function of transgenic mice models for Huntington's disease, researchers today told the American Society of Cell Biology's 50th Annual Meeting in Philadelphia.

New findings provide new clues on pathogenetic mechanisms of Alzheimer's disease

Pathological protein deposits linked to Alzheimer's disease and cerebral amyloid angiopathy can be triggered not only by the administration of pathogenic misfolded protein fragments directly into the brain but also by peripheral administration outside the brain.

New study signals hope for treatment of rare neurodegenerative disease

A new study led by St. Jude Children's Research Hospital scientists signals hope for treatment of a neurodegenerative disease and a new model for understanding the mechanism at work in other more common neurodegenerative disorders.

High sensitivity of Zetasizer Nano proves essential for protein aggregation studies

Dr Martin Muschol, Assistant Professor at the University of South Florida’s (USF) Department of Physics and his team are carrying out important research to gain a better understanding of protein aggregation phenomena, including protein crystallization and amyloid fibril growth. Using the Zetasizer Nano ZS, from Malvern Panalytical (Malvern Panalytical, UK), the USF researchers have been able to perform temperature controlled static and dynamic light scattering (DLS) measurements of protein hydration, protein interactions and aggregation kinetics in vitro.

Peer-reviewed articles elucidate role of clusterin in promoting tumor resistance to cancer treatment

OncoGenex Pharmaceuticals, Inc., announced today that two peer-reviewed articles have been published that further elucidate the biological function of clusterin, its role in promoting tumor resistance to cancer treatment, and the role of an inhibitor of clusterin such as custirsen (OGX-011) that is designed to knock down treatment resistance in the cells and enhance the effectiveness of cancer therapies.

Key molecular switch linked to HD identified

Scientists have identified a key molecular switch that may drive the onset of Huntington's disease (HD), an incurable neurodegenerative disorder that leads to severe disruptions in muscle coordination and cognitive function. The research, published by Cell Press in the December 24 issue of the journal Neuron, enhances the understanding of HD pathogenesis and may direct new strategies for treating this devastating brain disease.

Mouse study shows delaying the ageing process may offer protection against Alzheimer’s disease

Aging is the single greatest risk factor for Alzheimer's disease. In their latest study, researchers at the Salk Institute for Biological Studies found that simply slowing the aging process in mice prone to develop Alzheimer's disease prevented their brains from turning into a neuronal wasteland.

New biochemical probe may help in identifying toxic proteins associated with Alzheimer's disease

Alzheimer's disease (AD) is one of the most heartbreaking diagnoses a person can receive. This irreversible, progressive brain disease slowly destroys memory and thinking skills and eventually even the ability to carry out the simplest tasks

Study: HSP inhibitor could stop tumor formation and extend survival

Like yoga for office drones, cells do have coping strategies for stress. Heat, lack of nutrients, oxygen radicals - all can wreak havoc on the delicate internal components of a cell, potentially damaging it beyond repair. Proteins called HSPs (heat shock proteins) allow cells to survive stress-induced damage. Scientists have long studied how HSPs work in order to harness their therapeutic potential.

Protein aggregation is linked to many conformational diseases

Researchers at the Department of Biochemistry and Molecular Biology of Universitat Autònoma de Barcelona (UAB) have revealed the process by which proteins with a tendency to cause conformational diseases such as amyotrophic lateral sclerosis, familial amyloidotic polyneuropathy, familial amyloidotic cardiomyopathy, etc. finally end up causing them.

Researchers discover why Lou Gehrig's disease speeds along more rapidly in some patients than others

University of Florida scientists have discovered why a paralyzing brain disorder speeds along more rapidly in some patients than others - a finding that may finally give researchers an entry point toward an effective treatment for amyotrophic lateral sclerosis, often referred to as ALS or Lou Gehrig's disease.
