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.

RNA regulatory mechanism could be targeted to slow AD progression mediated by stress granules

A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 10, entitled, "Stress granules sequester Alzheimer's disease-associated gene transcripts and regulate disease-related neuronal proteostasis."

FDA-approved drug keeps light-sensitive photoreceptors alive in lab models of LCA 10

A National Institutes of Health team has identified a compound already approved by the U.S. Food and Drug Administration that keeps light-sensitive photoreceptors alive in three models of Leber congenital amaurosis type 10 (LCA 10), an inherited retinal ciliopathy disease that often results in severe visual impairment or blindness in early childhood.

Forward genetic screening reveals important pathways for sleep regulation in C. elegans

Although the regulation of sleep—how much, when, and how sleep occurs—is mainly considered to be controlled by the brain, sleep deprivation also affects the body, and signals from the body can affect sleep.

Researchers provide a framework for unifying and categorizing neurodegenerative diseases based on eight hallmarks

Researchers presented eight hallmarks of neurodegenerative diseases (NDDs), their in vivo biomarkers, and interactions to help categorize NDDs and specify patients within a specific NDD.

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.

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.
