DKK3 Initially Preserves Acinar Integrity Through MEK‐Fos Signaling, but Later Switches to an Oncogenic Role in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
In pancreatic cancer, the protein DKK3 is found to play a complex role: it initially slows early tumor growth but later promotes tumor aggressiveness. DKK3 expression evolves during progression and drives cancer severity by orchestrating cellular and molecular signaling pathways.

Realgar‐Induced CNS Toxicity: Exploring OTC‐Mediated Ornithine Regulation of ZBTB7A Inhibits Astrocyte Glycolysis Based on the Liver–Brain Axis

open access: yesAdvanced Science, EarlyView.
Arsenic in realgar induces CNS toxicity through direct and indirect effects: it activates ZBTB7A in astrocytes, which in turn inhibits glycolysis and impairs mice's learning, memory, and exploration; it also suppresses OTC in the liver to block the ornithine cycle, leading to blood ornithine accumulation that crosses into the frontal lobe and further ...

The Mitochondrial Protein RESISTANCE to APHIDS 9 Interacts with S40 to Resist Aphid Infestation by Modulating Reactive Oxygen Species Homeostasis in Maize (Zea mays)

open access: yesAdvanced Science, EarlyView.
This study identifies the mitochondrial protein RTA9, a member of the Domain of Unknown Function 641 family, together with its partner S40, as key regulators of aphid resistance in maize. RTA9 promotes S40 degradation and modulates reactive oxygen species accumulation.

A Hypoxia‐Responsive Single‐Atom Sonozyme for Targeted Sonocatalytic Therapy in Alleviating Atherosclerotic Plaque

open access: yesAdvanced Science, EarlyView.
A tetranitrogen‐coordinated single‐atom manganese catalyst (SMC) is fabricated with outstanding sonosensitization efficiency and multi‐enzyme‐like catalytic properties. To enable better targeting of M1 macrophages, hyaluronic acid (HA) is applied to modify the surface of SMC, yielding SMC‐HA nanozymes.

Deconstruction of the Anisotropic Magnetic Interactions from Spin‐Entangled Optical Excitations in van der Waals Antiferromagnets

open access: yesAdvanced Science, EarlyView.
A self‐consistent ab initio many‐body perturbation theory combined with locally exact dynamical mean field theory is employed to compute the sub‐bandgap electronic transitions in van der Waals antiferromagnets. The rich interplay between the magnetic ordering and spin‐entangled optical transitions, manifested as photoluminescence and absorption ...

METTL10‐Mediated PIAS3 Methylation Links Purine Metabolism to Gastric Cancer Progression

open access: yesAdvanced Science, EarlyView.
METTL10‐mediated methylation of PIAS3 at K442 inhibits its SUMO E3 ligase activity toward MITF. This reduces MITF SUMOylation and subsequent RNF4‐mediated ubiquitination, leading to MITF protein accumulation and gastric cancer progression. Abstract Metabolic dysregulation plays a significant role in the development of gastric cancer (GC).

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

open access: yesAdvanced Science, EarlyView.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

A Novel Zinc(II) Complex for Sonodynamic Therapy Induces Pyroptosis of Breast Cancer Cells and Enhances Anti‐Tumor Immune Response

open access: yesAdvanced Science, EarlyView.
Although Zinc(II) complexes are effective in photodynamic therapy, their efficacy is limited by the poor tissue penetration of light. This work introduces a novel zinc(II) complex for sonodynamic therapy. Under ultrasound activation, it generates substantial singlet oxygen, induces pyroptosis in breast cancer cells, and promotes anti‐tumor immune ...

Depletion of Sorcs3 Activates Totipotency in Mouse Embryonic Stem Cells by Modulating Key Signaling Pathways

open access: yesAdvanced Science, EarlyView.
In this article, Shuai and colleagues found that depletion of Sorcs3 could activate totipotency in mESCs, promising bidirectional differentiation potential to embryonic and extraembryonic lineages. The underlying mechanism might be activation of Tfap2c and repression of TGF‐β, PI3K‐AKT, and lysosome pathways.
