Dual‐Gene Edited Extracellular Vesicles Remodel the Redox Homeostasis to Inhibit Ferroptosis in Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
ABSTRACT Intervertebral disc degeneration (IDD) is driven by ferroptosis of nucleus pulposus cells (NPCs) as a core pathological mechanism. Nucleus pulposus progenitor cells (NPPCs), exhibiting stem cell‐like properties, yield extracellular vesicles (PEVs) with high affinity for NPCs and enable targeted phenotypic regulation.

Selective loss of GABAB receptors in orexin/hypocretin-producing neurons results in disrupted sleep/wakefulness architecture [PDF]

open access: yes, 2007
We generated mice with a selective loss of GABAB receptors in orexin neurons. Orexin neurons in these GABAB1<sup>-/-(orexin)</sup> mice showed reduced responsiveness to GABA<sub>A</sub> receptor agonists due to a ...

Structural Basis of Shiga Toxin Neutralization by Human Antibodies Targeting Canonical Receptor‐Binding and Non‐Canonical Assembly Sites

open access: yesAdvanced Science, EarlyView.
Cryo‐electron microscopy structures reveal two distinct neutralization mechanisms of fully human monoclonal antibodies targeting the Shiga toxin 1a B subunit. RDS059 occludes the Gb3 receptor‐binding site, whereas RDS045 engages a lateral quaternary epitope to disrupt holotoxin assembly.

Modulation of cholinergic synaptic transmission in an identified locust sensory pathway [PDF]

open access: yes, 2000
The monosynaptic connection between the locust forewing stretch receptor (fSR) and the first basalar motoneuron (BAl) is part of a sensory pathway involved in flight.

Macrophage PARP7 Alleviates Septic Cardiomyopathy by Interacting With TBK1 and Suppressing TBK1‐Driven Inflammatory Response

open access: yesAdvanced Science, EarlyView.
In septic cardiomyopathy, PARP7 directly binds TBK1 and mediates its ADP‐ribosylation, thereby repressing TBK1‐driven proinflammatory signaling in macrophages. ABSTRACT Septic cardiomyopathy is a life‐threatening complication of sepsis, and an uncontrolled inflammatory response represents a key pathogenic mechanism. PARP7 negatively regulates the IFN‐I

Chronic cocaine enhances release of neuroprotective amino acid taurine: a microdialysis study [PDF]

open access: yes, 2008
Cocaine inhibits high-affinity neurotransmitter uptake at the presynaptic nerve terminals to increase synaptic levels of dopamine, norepinephrine and serotonin^1^. This increase of synaptic dopamine may cause neurotoxicity^2,3^.

The Cancer Cell Metabolic Reprogramming Remodels the Tumor Microenvironment: Molecular Mechanisms and Therapeutic Strategies

open access: yesAdvanced Science, EarlyView.
This review elucidates how cancer cell metabolic reprogramming—across glucose, lipid, amino acid, and nucleotide pathways—remodels the tumor microenvironment to suppress anti‐tumor immunity and promote immune escape. Targeting these metabolic axes offers promising strategies to overcome immunotherapy resistance and enhance cancer treatment.

Spatiotemporal Multi‐Omic Mapping Reveals Liver‐Muscle Metabolic Crosstalk in Cancer Cachexia

open access: yesAdvanced Science, EarlyView.
The interactive CCAtlas platform delineates cross‐species, spatiotemporal, and sex‐specific molecular dynamics and metabolic rewiring across organs during cancer cachexia. Hepatic Gamt downregulation curtails hepatic creatine synthesis to trigger systemic creatine insufficiency and consequent skeletal muscle atrophy in LLC tumour‐bearing mice ...

Sex differences in AMPA receptor trafficking proteins

open access: yesBiology of Sex Differences
AMPA receptors are a type of ionotropic glutamate receptor that is important for fast excitatory neurotransmission. healthy brain function. Glutamate signaling is regulated, in part, by the trafficking of glutamate receptors in and out of the synapse ...

YTHDC1 Orchestrates Glucose and Glutamate Rewiring to Overcome Lethal Metabolic Stress in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
Lai et al. find that m6A reader YTHDC1 is specifically overexpressed in triple‐negative breast cancer (TNBC) and orchestrates glucose and glutamine metabolism in an m6A‐dependent manner to confer robust adaptability to lethal metabolic stress. Leveraging YTHDC1 knockdown‐induced metabolic vulnerability, an ATF4 mRNA‐targeted nanotherapy is developed to
