Helicene-grafted vinyl- and carbene-osmium complexes: an example of acid-base chiroptical switching

open access: yes, 2014
International audienceThe first helicene-based carbene-osmium complex has been prepared from a vinyl-osmium derivative and this system has been shown to behave as a potential acid-base triggered chiroptical ...

Endowing Flexibility of Alveolar Type II Cells to Recapitulate Development From Lung Bud to Alveoli

open access: yesAdvanced Science, EarlyView.
Adult human alveolar type 2 cells are chemically reprogrammed into expandable alveolar progenitor‐like cells that acquire bud tip‐like features during expansion and form organoids that mature into alveolar‐like structures. These organoids model influenza A virus infection and innate immune responses in vitro, while transplanted cells engraft ...

MAPA: A Semantic Network Framework for Functional Module Discovery and Interpretation in Multi‐Omics Data

open access: yesAdvanced Science, EarlyView.
MAPA transforms complex multi‐omics data into biologically coherent functional modules by integrating pathway information with molecular interaction networks. Retrieval‐augmented large language models then generate structured, literature‐informed interpretations.

Lactylation‐Driven PROS1‐TYRO3‐CARF Signaling Promotes Therapy‐Induced Senescence Escape and Radioresistance in Meningioma

open access: yesAdvanced Science, EarlyView.
A glycolysis‐driven epigenetic switch promotes therapy resistance in meningioma. Increased lactate production enhances histone H3K27 lactylation, which activates PROS1 secretion. Secreted PROS1 engages TYRO3 signaling to degrade the senescence regulator CARF, allowing cancer cells to escape growth arrest.

A Gut‐Brain Axis Underlying Succinate‐Associated Compulsive‐Like Behavior

open access: yesAdvanced Science, EarlyView.
Gut‐derived succinate is associated with an excitatory‐inhibitory imbalance in dmPFC glutamatergic neurons, involving microglial SUCNR1 activation and vagal afferent signaling via upregulated gut 5‐HT4 receptors along the DVC‐CeA‐dmPFC circuit, changes that are linked to excessive compulsive‐like behavior.

Developmental Environmental Chronotoxicity by Polystyrene Nanoplastics Exacerbates High‐Fat Diet‐Induced Pediatric MAFLD Through Circadian Disruption and Mitochondrial Dysfunction

open access: yesAdvanced Science, EarlyView.
Polystyrene nanoplastics exacerbate high‐fat diet‐induced metabolic dysfunction in an age‐dependent manner. Juvenile mice exhibit greater susceptibility, characterized by circadian disruption, impaired mitochondrial function, reduced energy metabolism, and enhanced hepatic lipid accumulation.

Asymmetric Structure‐Driven Functional Synergy: A Multistimuli‐Activated Janus Nanomotor for Self‐Amplifying NO Cascade Therapy

open access: yesAdvanced Science, EarlyView.
The Janus nanomotors leverage an “asymmetric structure‐driven functional synergy” strategy to orchestrate spatiotemporally coordinated catalytic functions, in situ self‐amplifying NO generation, and deep tumor penetration, thereby enabling controllable, sustained, and uniform NO generation within the tumor microenvironment.

Dual Compartmentalization of GSTA4 Suppresses Ferroptosis to Drive Antiandrogen Resistance in Prostate Cancer

open access: yesAdvanced Science, EarlyView.
The schematic diagram depicts a compartmentalized anti‐ferroptotic defense mechanism mediated by GSTA4. GSTA4 is upregulated and localizes to the cytoplasm in ENZR cells, where it detoxifies 4‐HNE via a non‐canonical GSH‐dependent pathway. Under oxidative stress, GSTA4 translocates to mitochondria, interacts with PGAM5, and blocks Drp1 Ser637 ...

Osmium mediated decarbonylation of aldehydes and ketones. Synthesis, structure and reactivities of some osmium carbony1 complexes

open access: yes, 2003
2406-2415Reaction of [Os(PPh3) 3Br2] with salicylaldehyde or 2-hydroxyacetophenone or 2-hyd roxynaphthaldehyde in the presence of a base results in the decarbonylation of these phenolic ligands affording an osmium carbonyl complex, viz . [Os(PPh3)2(CO)
