A Unifying Thermodynamic Model for Phase Separation and Aging of Biopolymers

Advanced Science, EarlyView.
Phase separation and aging of intrinsically disordered proteins are placed in a unifying framework. A thermodynamically consistent time‐dependent version of associating‐polymer theory shows how the processes are intricately coupled. Assuming aging to occur through interacting sites resulting from reversible conformational transitions, the model ...

Preclinical Detection of Prions in Blood of Nonhuman Primates Infected with Variant Creutzfeldt-Jakob Disease

Emerging Infectious Diseases, 2020
Variant Creutzfeldt-Jakob disease (vCJD) is caused by prion infection with bovine spongiform encephalopathy and can be transmitted by blood transfusion. Protein misfolding cyclic amplification (PMCA) can detect prions in blood from vCJD patients with 100%

Current Challenges of Transcription Compartmentalization Research

Advanced Science, EarlyView.
Transcription factors, coactivators, and RNA polymerase II assemble into transcription compartments ranging from small, defined complexes to liquid‐like condensates. This review unifies these seemingly competing descriptions along a single continuum and asks what these compartments have been shown to do, and what they have not, revealing that the most ...

Yeast Prions and Their Prion-Forming Domain [PDF]

Cell, 2000
We have learned much about prion biology through the study of yeast prions and their associated PrDs, but caution must be exercised in extrapolating these findings directly to mammalian prion behavior. It must not be forgotten that mammalian PrPSc is an infectious agent that can spread from cell to cell while there is no evidence of cell-to-cell ...

Reply to “Reassessing the Proposed Creatine–PrP Axis in Endometriosis: Methodological and Mechanistic Considerations”

Advanced Science, EarlyView.
ABSTRACT This Correspondence is a formal response to the Comment by Dr. Machado regarding our publication “Creatine Promotes Endometriosis by Inducing Ferroptosis Resistance via Suppression of PrP.” We address several conceptual concerns raised in the Comment and clarify the physiological relevance of creatine concentrations, the methodological ...

Prion and prion-like diseases in animals

Virus Research, 2015
Transmissible spongiform encephalopaties (TSEs) are fatal neurodegenerative diseases characterized by the aggregation and accumulation of the misfolded prion protein in the brain. Other proteins such as β-amyloid, tau or Serum Amyloid-A (SAA) seem to share with prions some aspects of their pathogenic mechanism; causing a variety of so called prion-like

Social Determinants of Health and Health‐Related Quality of Life: The Potential Mediating Role of Social Activities, Access to Medical Services, and Access to Social Services

Australian Journal of Social Issues, EarlyView.
ABSTRACT This study explored the mediating influences of access to social activities, social services, and health and medical services on the relationship between social determinants of health and health‐related quality of life. A survey of 602 adults was conducted in a regional area of Australia.

Biology and Genetics of Prions Causing Neurodegeneration

Annual Review of Genetics, 2013
Prions are proteins that acquire alternative conformations that become self-propagating. Transformation of proteins into prions is generally accompanied by an increase in β-sheet structure and a propensity to aggregate into oligomers.

Genetic Modifiers of ABCA1 Activity Interact with APOE Isoforms to Mediate Alzheimer's Disease Risk

Annals of Neurology, EarlyView.
Objective ATP‐binding cassette transporter A1 (ABCA1) has been associated with Alzheimer's disease (AD), but the mechanisms by which it impacts disease risk are unknown. ABCA1 is known to bind apolipoprotein E (ApoE) and catalyze apolipoprotein lipidation.

Neurotransmitter‐Defined Degeneration Patterns in Sporadic and C9orf72‐Associated Amyotrophic Lateral Sclerosis: Predilection to GABAergic, Serotonergic, Opioid, Glutamatergic, Endocannabinoid, and Microglial Systems—Implications for Therapy Development

Annals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a markedly distinctive clinical and neuroradiological signature, with the preferential involvement of specific brain networks and the apparent sparing of others. The molecular underpinnings of the strikingly selective anatomical vulnerability have not been fully elucidated to date despite the potential ...
