Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Objective: There are increasing clues related to the fact that oxidative stress has a role in physiopathology of schizophrenia. On the other hand, the studies comparing oxidative stress in schizophrenia in relevance to the state of ilness whether ...

Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

The Application of a Statistical Model Investigating Reactive Oxygen Species in Premature Ageing Syndromes [PDF]
The premature ageing syndromes Hutchison-Gilford Progeria Syndrome (HGPS) and Restrictive Dermopathy (RD) are rare genetic disorders that result in greatly accelerated ageing. RD is neonatal fatal, whereas children suffering from HGPS age approximately 8

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Covalent modifications of albumin CYS34 as biomarker of oxidative stress
Protein carbonylation is an irreversible process, induced by oxidants and reactive carbonyl species (RCS), the latter deriving from lipid peroxidation and oxidation of reducing sugars.

The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...
