Proteasomes on the chromosome [PDF]
Targeted proteolysis plays an important role in the execution and regulation of many cellular events. Two recent papers in Science identify novel roles for proteasome-mediated proteolysis in homologous chromosome pairing, recombination, and segregation during meiosis.

ABSTRACT Astrocyte reactivity critically shapes neuroinflammatory outcomes after ischemic stroke, yet the upstream regulators governing astrocyte state transitions remain incompletely defined. Here, we identify the immunoproteasome subunit low molecular weight protein 2 (LMP2) as an important modulator of astrocyte functional remodeling following ...

The Role of the Ubiquitin System in Eye Diseases
The ubiquitin–proteasome system (UPS) is a fundamental process that regulates various biological functions, including immune response, cell cycle, oxidative stress, migration, and cellular proliferation.

Structural Polymorphism of polyG Inclusions Revealed by In Situ Cryo-Electron Tomography. [PDF]
Correlative cryo‐electron tomography in primary cortical neurons and NIID mouse brain tissue reveals that polyG inclusions are interconnected ribbon‐like assemblies rather than canonical amyloid fibrils. Multiple compartment‐specific ribbon states show distinct 26S proteasome accessibility, while cytoplasmic ribbons contact and deform ER‐like ...

Mitochondrial SLC25A46 is upregulated in ovarian cancer (OC) and correlates with poor prognosis. SLC25A46 stabilizes CACT to activate fatty acid oxidation, increasing ATP and NADPH production to drive cell proliferation and ferroptosis evasion. SLC25A46 silencing sensitizes OC cells to ferroptosis and carboplatin, offering a promising therapeutic ...

Peroxisome proliferator-activated receptor γ (PPARγ), a member of nuclear hormone receptors, forms a heterodimeric DNA binding complex with retinoid X receptor (RXR) and serves as a transcriptional regulator of gene expression.

Rising interest in the mechanism and function of the proteasomes and the ubiquitin system revealed that it is hard to find any aspect of the cellular metabolic network that is not directly or indirectly affected by the degradation system. This includes the cell cycle, the "quality control" of newly synthesized proteins (ERAD), transcription factor ...

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity
This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

Recent advances in the treatment of Malaria
Malaria is an infectious disease caused by protozoan parasites belonging to the Plasmodium species. The disease has been a major cause of mortality and morbidity, especially in populations of African and SouthEast Asian countries.
