Engineering a membrane protein chaperone to ameliorate the proteotoxicity of mutant huntingtin.

Toxic protein aggregates are associated with various neurodegenerative diseases, including Huntington's disease (HD). Since no current treatment delays the progression of HD, we develop a mechanistic approach to prevent mutant huntingtin (mHttex1) aggregation. Here, we engineer the ATP-independent cytosolic chaperone PEX19, which targets peroxisomal membrane proteins to peroxisomes, to remove mHttex1 aggregates.

Association of Impaired Relaxation Mitral Inflow Pattern (Grade 1 Diastolic Function) with Long-term Non-Cardiovascular and Cardiovascular Mortality.

Background: Abnormalities of left ventricular (LV) diastolic function are established independent predictors of heart failure (HF) and mortality.

Objectives: To determine whether the association of diastolic function with all-cause mortality is driven by cardiovascular or non-cardiovascular death and if impaired relaxation mitral inflow filling pattern is a risk marker.

Methods: Diastolic function was graded by the Mayo Clinic algorithm utilizing the well characterized prospective Olmsted County Heart Function Study.

The Future of MXenes: Exploring Oxidative Degradation Pathways and Coping with Surface/Edge Passivation Approach.

The MXene, which is usually transition metal carbide, nitride, and carbonitride, is one of the emerging family of 2D materials, exhibiting considerable potential across various research areas. Despite theoretical versatility, practical application of MXene is prohibited due to its spontaneous oxidative degradation. This review meticulously discusses the factors influencing the oxidation of MXenes, considering both thermodynamic and kinetic point of view.

Effects of Epothilone D on Social Defeat Stress-induced Changes in Microtubule-related and Endoplasmic Reticulum Stress Protein Expression.

Objective: Epothilone D (EpoD), microtubule (MT) stabilizing agent, demonstrated promising results in the animal models of Alzheimer's disease, Parkinson's disease and schizophrenia. The present study sought to investigate preventive effects of EpoD on altered changes of MT related proteins and endoplasmic reticulum (ER) stress proteins induced by social defeat stress (SDS).

Methods: We measured protein expression levels of α-tubulin and its post-translational modifications, MT-associated protein 2, stathmin1 and 2 with their phosphorylated forms, and ER stress markers, 78-kDa glucose-regulated protein (GRP-78) and CCAAT/enhancer binding protein (C/EBP)-homologous protein (CHOP) in the prefrontal cortex (PFC) and hippocampus (HIP) of C57BL/6J strain mice treated with EpoD (2 mg/kg) or its vehicle, dimethylsulfoxide (DMSO), and exposed to SDS.
