Human cachexia induces changes in mitochondria, autophagy and apoptosis in the skeletal muscle [PDF]
Cachexia is a wasting syndrome characterized by the continuous loss of skeletal muscle mass due to imbalance between protein synthesis and degradation, which is related with poor prognosis and compromised quality of life.

Copper Overload Affects α‐Synuclein Clearance Mechanisms in a Parkinson's Disease In Vitro Model
This study reveals that copper overload disrupts neuronal protein clearance, leading to the accumulation of α‐synuclein and its phosphorylated form (p‐S129). By blocking autophagy and impairing the ubiquitin–proteasome system, copper promotes toxic aggregation in dopaminergic cells.

Autophagy-Related Beclin 1 and Head and Neck Cancers.
Beclin 1, a positive regulator of autophagy, behaves as a double-edged sword in tumorigenesis. Beclin 1 contributes to tumor suppression by removing defective or damaged organelles and other cellular components; however, its activity can also stimulate cancer initiation and progression.

Depletion of Beclin-1 due to proteolytic cleavage by caspases in the Alzheimer's disease brain
The Beclin-1 protein is essential for the initiation of autophagy, and recent studies suggest this function may be compromised in Alzheimer's disease (AD).

Negative Regulation of Vps34 by Cdk Mediated Phosphorylation [PDF]
Vacuolar protein sorting 34 (Vps34) complexes, the class III PtdIns3 kinase, specifically phosphorylate the D3 position of PtdIns to produce PtdIns3P. Vps34 is involved in the control of multiple key intracellular membrane trafficking pathways including ...

A bioinspired nanozyme—triphenylphosphonium (TPP)‐dendritic mesoporous silica nanoparticle (DMSN)‐Fe/Cu—mimics mitochondrial complex IV and targets mitochondria to regulate cellular energy metabolism. This approach markedly boosts bone regeneration in vivo, as demonstrated by enhanced bone volume and mineral density in critical‐sized bone defects rat ...

Background The ubiquitin-proteasome system and macroautophagy (hereafter referred to autophagy) are two complementary pathways for protein degradation. Emerging evidence suggests that proteasome inhibition might be a promising approach for tumor therapy.

Brainiac Caspases: Beyond the Wall of Apoptosis [PDF]
For the last two decades, caspases, a family of cysteine-aspartic proteases, have evolved from being considered solely as regulators of apoptosis or inflammation to having a wider range of functions.

HSP90α is significantly upregulated in platelets from sepsis patients, with its origin from megakaryocyte‐derived trafficking. Furthermore, activated platelets secrete HSP90α into the extracellular space in both free and exosome‐associated forms. Finally, extracellular HSP90α directly engages TLR4 on neutrophils to induce autophagy, leading to NET ...

The Aging Heart: Mitophagy at the Center of Rejuvenation. [PDF]
Aging is associated with structural and functional changes in the heart and is a major risk factor in developing cardiovascular disease. Many recent studies have focused on increasing our understanding of the basis of aging at the cellular and molecular ...
