Proteostasis News and Research

RSS

Each mammalian cell contains up to 20,000 proteins, all of which must be maintained and regulated. Proteostasis is a complex pathway that functions to maintain all of the proteins within and around a cell.

Researchers corroborate the importance of exercise for cognitive function

Accumulating evidence finds that exercise can improve brain function and delay or prevent the onset of neurodegenerative diseases such as Alzheimer's and Parkinson's disease.

SARS-CoV-2-encoded protein ameliorates neuromuscular degeneration in fly models of neurodegenerative diseases

Researchers explored the in vivo efficacy of SARS-CoV-2-encoded proteins against neuromuscular degeneration associated with ribosome stalling.

Insights into molecular folding of AAT protein will help develop new therapies for alpha-1 antitrypsin deficiency

In a major new development in the quest to develop better gene therapies with which to treat a host of diseases, researchers at the University of Massachusetts Amherst and UMass Chan Medical School recently announced that they have mapped the expression and maturation of the protein alpha-1 antitrypsin (AAT) with unprecedented clarity.

How diet and nutrition impacts lifespan

In a recent study published in the journal Cell, researchers analyzed the association between human longevity to growth and metabolic pathways.

New mouse line reveals the state of protein balance in the mammalian brain for the first time

Proteins are the "tools" of our cells – they are essential to all vital tasks. However, they are only able to do their jobs if they fold correctly and adopt their respective, very specific 3D structure.

UC San Diego scientists develop new method to keep cultured cells healthy

Hematopoietic stem cells — the precursors to blood cells — have been notoriously difficult to grow in a dish, a critical tool in basic research.

Research shows how loss of de-N-glycosylation enzyme causes detrimental effects

Peptide: N-glycanase (NGLY1) is an evolutionarily conserved enzyme for removing N-linked glycans (N-glycans) from glycoproteins and is involved in proteostasis of N-glycoproteins in the cytosol. In 2012, a rare genetic disorder called NGLY1 deficiency was discovered by an exome analysis.

Study may lead to new treatments for a wide range of neurological conditions

New research published today sheds important light on how the production of a key protein in the brain is controlled, which could pave the way for new treatments for a wide range of neurological conditions.

Experimental drug reverses key symptoms of Alzheimer's disease in mice

Researchers at Albert Einstein College of Medicine have designed an experimental drug that reversed key symptoms of Alzheimer's disease in mice.

22 Apr 2021

SARS-CoV-2 nucleoprotein can trigger α-synuclein amyloid fibril formation

A new study, released as a preprint on the bioRxiv* server, casts some light on the pathogenesis of acute and subacute neurological complications associated with COVID-19.

Researchers describe a new approach to treating Parkinson's disease

Parkinson's disease is the second most common, age-related, neurodegenerative disease: In Germany alone, about 300,000 people are affected and experience sometimes major limitations to their quality of life.

20 Mar 2021

Researchers use EPR spectroscopy to learn more about "Parkinson protein"

The protein α-synuclein is one of the most abundant proteins in the human brain. It is often referred to as the "Parkinson protein", as deposition of this protein in brain cells is a hallmark of Parkinson's disease.

Potential new treatment approach to fatal COVID-19

Researchers from the University of Colorado Anschutz Medical Campus and Pathways Bioscience in the United States have found that activating a transcription factor involved in oxidative stress regulation, antiviral activity, and inflammation may serve as a new treatment approach to coronavirus disease 2019 (COVID-19).

18 May 2020

Researchers discover a new mode of protein degradation by ubiquitin-proteasome system

The proteasome is a major proteolytic machine that regulates cellular proteostasis through selective degradation of ubiquitylated proteins.

28 Apr 2020

Protective brain-cell housekeeping mechanism may also be involved in regulating sleep

An important biological mechanism that is thought to protect brain cells from neurodegenerative diseases such as Alzheimer's and Parkinson's may also be involved in regulating sleep, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

12 Mar 2020

Researchers establish a gene expression profile associated with cachexia in cancer patients

It is estimated that as many as 80% of advanced-stage cancer patients may develop cachexia, a potentially fatal metabolic syndrome characterized by extreme weight loss and muscle wasting, but scientists do not yet fully understand why it is more frequently associated with certain kinds of tumor than others, or why not all cancer patients develop it.

ADDF announces new awards through its Diagnostics Accelerator initiative

The Alzheimer's Drug Discovery Foundation announced six new investments totaling $6 million through its Diagnostics Accelerator initiative.

Scientists reverse learning and memory deficits with drugs in animal model of Down syndrome

In a surprising finding using the standard animal model of Down syndrome (DS), scientists were able to correct the learning and memory deficits associated with the condition -- the leading genetic cause of cognitive disability and the most frequently diagnosed chromosomal disorder in the U.S. -- with drugs that target the body's response to cellular stresses.

Stony Brook-led study reveals how proteome collapse process drives cell death and aging

Cells undergo natural aging and death, processes that impact a multitude of cellular factors. A new Stony Brook University-led study, to be published in PNAS, provides a biophysical model that reveals how damage accumulates in the shapes of cellular proteins with age and is a trigger to death.

Scientists demonstrate influence of food odors on proteostasis

The smell of food induces a variety of physiological processes in our body. Thus, the production of saliva and digestive enzymes is stimulated before the actual food intake in order to prepare the gastrointestinal tract for the upcoming digestive process.
