Comparative Studies in the A30P and A53T α-Synuclein C. elegans Strains to Investigate the Molecular Origins of Parkinson's Disease

Frontiers in Cell and Developmental Biology, 2021
The aggregation of α-synuclein is a hallmark of Parkinson's disease (PD) and a variety of related neurological disorders. A number of mutations in this protein, including A30P and A53T, are associated with familial forms of the disease. Patients carrying

Pharmacological inhibition of α-synuclein aggregation within liquid condensates

Nature Communications
Aggregated forms of α-synuclein constitute the major component of Lewy bodies, the proteinaceous aggregates characteristic of Parkinson’s disease. Emerging evidence suggests that α-synuclein aggregation may occur within liquid condensates formed through ...

Heat shock-induced phosphorylation of TAR DNA-binding protein 43 (TDP-43) by MAPK/ERK kinase regulates TDP-43 function [PDF]

, 2017
TAR DNA-binding protein (TDP-43) is a highly conserved and essential DNA- and RNA-binding protein that controls gene expression through RNA processing, in particular, regulation of splicing.

Antipsychotic olanzapine-induced misfolding of proinsulin in the endoplasmic reticulum accounts for atypical development of diabetes

eLife, 2020
Second-generation antipsychotics are widely used to medicate patients with schizophrenia, but may cause metabolic side effects such as diabetes, which has been considered to result from obesity-associated insulin resistance.

The potential role of dietary polyphenols in Parkinson’s disease [PDF]

, 2011
Cumulative evidence now suggests that the abnormal aggregation of the neuronal protein alpha-synuclein is critically involved in the pathogenesis of synucleinopathies, of which Parkinson’s disease (PD) is the most prevalent. Development of neuropathology

Methionine 129 variant of human prion protein oligomerizes more rapidly than the valine 129 variant - Implications for disease susceptibility to Creutzfeldt-Jakob disease [PDF]

, 2004
The human PrP gene (PRNP) has two common alleles that encode either methionine or valine at codon 129. This polymorphism modulates disease susceptibility and phenotype of human transmissible spongiform encyphalopathies, but the molecular mechanism by ...

The role of binding site on the mechanical unfolding mechanism of ubiquitin. [PDF]

, 2015
We apply novel atomistic simulations based on potential energy surface exploration to investigate the constant force-induced unfolding of ubiquitin. At the experimentally-studied force clamping level of 100 pN, we find a new unfolding mechanism starting ...

The proteasome biogenesis regulator Rpn4 cooperates with the unfolded protein response to promote ER stress resistance

, 2019
Misfolded proteins in the endoplasmic reticulum (ER) activate the unfolded protein response (U PR), which enhances protein folding to restore homeostasis.
