NAD+‐Boosters Improve Mitochondria Quality Control In Parkinson's Disease Models Via Mitochondrial UPR

Advanced Science, EarlyView.
Treatment of MPTP‐incubated cells with NAD+‐boosters increase the UPRmt/mitophagy‐related mitochondria quality control (MQC). Disturbed plasma UPRmt‐mitophagy‐mediated MQC profiles in PD patient samples. NMN inhibits motor deficit and forestalls neuropathology phenotypes of PD mice, which is required the atf4‐medicated UPRmt pathway.

UCP2 Upregulates ACSL3 to Enhance Lipid Droplet Release from Acinar Cells and Modulates the Sirt1/Smad3 Pathway to Promote Macrophage‐to‐Myofibroblast Transition in Chronic Pancreatitis

Advanced Science, EarlyView.
These findings suggest that UCP2 promotes LD formation and release in acinar cells by upregulating ACSL3 expression. This alteration in the local lipid metabolic environment indirectly drives the MMT process. Additionally, UCP2 may regulate the acetylation of Smad3 through Sirt1, enhancing its nuclear activity and activating the TGF‐β/ Smad3 signaling ...

An Allele of Glutamate Formiminotransferase Triggers 5‐Methyl‐Tetrahydrofolate‐to‐MeFox Conversion and Facilitates Folate Biofortification in Maize

Advanced Science, EarlyView.
This work demonstrates the distinct roles of the glutamate formiminotransferase (GFT) enzyme in plants. The GFT triggers the conversion of 5‐methyl‐tetrahydrofolate to MeFox in plants, a process distinct from its role as a formiminotransferase in mammals.

Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

Advanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

WSGC@FA@PEG/PEI‐SPIONs Mitigate Chemoresistance in Gastric Adenocarcinoma by Modulating the Notch Signaling Pathway and Mitophagy

Advanced Science, EarlyView.
WSGC peptide reverses drug resistance in GA by modulating the Notch signaling pathway and mitophagy at the molecular level. Abstract This study investigates the molecular mechanisms by which superparamagnetic iron oxide nanoparticles (SPIONs) loaded with the WSGC peptide (WSGC@FA@PEG/PEI‐SPIONs)—a 40‐amino acid polypeptide derived from apoC‐III ...

Alistipes senegalensis is Critically Involved in Gut Barrier Repair Mediated by Panax Ginseng Neutral Polysaccharides in Aged Mice

Advanced Science, EarlyView.
An integral functional axis through which GPN and functional metabolites of Alistipes senegalensis can hydrolyze tryptophan into indoles. Furthermore, the Alistipes senegalensis‐indole‐AhR pathway is found to be associated with increased expression of tight junction‐associated proteins and activation of gut stem cells.

A Two‐Protein Chemoreceptor Complex Regulates Oxygen Thresholds in Bacterial Magneto‐Aerotaxis

Advanced Science, EarlyView.
Magnetotactic bacteria align with Earth's magnetic field, helping them migrate toward low‐oxygen environments. This study reveals how Magnetospirillum gryphiswaldense uses a specialized flavin adenine dinucleotide (FAD)‐dependent chemoreceptor, composed of two interacting proteins, for precise navigation in oxygen gradients.

Human iPSC‐Derived Mononuclear Phagocytes Improve Cognition and Neural Health across Multiple Mouse Models of Aging and Alzheimer's Disease

Advanced Science, EarlyView.
Short‐term intravenous treatments with iPSC‐derived mononuclear phagocytes (iMPs) improve cognitive decline and neural health in two mouse models of aging and in the 5xFAD mouse model of Alzheimer's disease. iMPs reduce levels of serum amyloid proteins that increase in aging and improve the health of hippocampal microglia and mossy cells.

A Mass Spectrometry Approach Reveals Fatty Acid Isomerism in Tomato Cold Tolerance

Advanced Science, EarlyView.
An enhanced mass spectrometry approach reveals fatty acids (FAs) and FA isomers that are critical for tomato cold tolerance. Applying specific FA isomers can partially rescue cold sensitivity in tomato mutant plants, highlighting the importance of FA isomers in plant cold stress adaptation.
