TGFBI Maintains Fibrocartilage Homeostasis by Restraining O‐GlcNAcylation to Inactivate and Destabilize ADAMTS16 in Temporomandibular Joint Osteoarthritis

open access: yesAdvanced Science, EarlyView.
TGFBI deficiency elevates O‐GlcNAcylation, promoting the transcriptional activation of ADAMTS16 and OGT‐mediated post‐translational modification of ADAMTS16 at Ser1170. This leads to its stabilization and accumulation, driving chondrocyte metabolic disorders and senescent phenotypes, ultimately resulting in fibrocartilage dysfunction and TMJOA ...

Deciphering Structure‐Bubble‐Mass Transfer Relationships in Water Electrolysis Through Electrode Morphology Regulation

open access: yesAdvanced Science, EarlyView.
Electrode morphology is shown to govern oxygen‐bubble dynamics and interfacial mass transfer during water electrolysis. Positive‐curvature nanoneedles promote rapid release of small bubbles, sustain electrolyte renewal, and minimize mass‐transport losses, whereas flat and concave architectures increasingly retain bubbles.

Matrix Rigidity Mechanoprimes Microglia for Inflammation Through Cytoskeletal‐to‐Nuclear Signaling and 3D Spatio‐Epigenomic Remodeling

open access: yesAdvanced Science, EarlyView.
Pathological tissue rigidity mechanoprimes microglia by enhancing actin cytoskeleton–nucleus coupling and chromatin opening at rigidity‐responsive cis‐regulatory elements (mechanoCREs). Subsequent NF‐κB/p65 signaling converges on this permissive regulatory state to amplify inflammatory gene expression and microglial activation.

Curvature‐Directed Elongation and Chiral Tilting Drive Asymmetric Tissue Patterning

open access: yesAdvanced Science, EarlyView.
Curvature and cell handedness together break tissue symmetry. On convex and concave surfaces, cells elongate along opposite geometric axes and tilt in a consistent chirality‐driven direction, yielding opposite alignment patterns from the same cells. Reversing intrinsic cell chirality reverses both.

GSLR Drives Lung Adenocarcinoma as a Critical Regulator of Energy Homeostasis Through Creatine Kinase B Activation

open access: yesAdvanced Science, EarlyView.
This study identifies the glucose/glutamine sensitive lncRNA GSLR as a driver of lung adenocarcinoma progression. Nutrient restriction reduces chromatin accessibility at the GSLR locus and blocks CTCF‐mediated transcriptional regulation. GSLR directly interacts with DHX9 and recruits it to the CKB promoter, arresting R‐loop accumulation and promoting ...

A Hypothalamic Oxytocinergic–Sympathetic Axis Couples Anxiety Dysregulation With Impaired Tendon–Bone Repair

open access: yesAdvanced Science, EarlyView.
RCI is associated with functional suppression of oxytocinergic neurons in the PVN. Reduced PVNOXT neuronal activity contributes to altered sympathetic regulation involving the IML–sympathetic chain pathway, accompanied by changes in norepinephrine signaling at the BTI.

Secure domination number of k-subdivision of graphs

open access: yesDiscrete Mathematics, Algorithms and Applications
Let [Formula: see text] be a simple graph. A dominating set of [Formula: see text] is a subset [Formula: see text] such that every vertex not in [Formula: see text] is adjacent to at least one vertex in [Formula: see text]. The cardinality of a smallest dominating set of [Formula: see text], denoted by [Formula: see text], is the domination number of [

Aged ZnO Nanoparticles Promote Breast Cancer Lung Metastasis by Remodeling the Pulmonary Microenvironment Through the CXCL10/Wnt/β‐Catenin Axis

open access: yesAdvanced Science, EarlyView.
In summary, pulmonary exposure to ZnO NPs, particularly aged NPs, promotes breast cancer metastasis by remodelling the lung tumour microenvironment. Aged ZnO NPs enrich M2‐macrophages, MDSCs and activated CAFs to form an immunosuppressive metastatic niche. CXCL10 from these cells drives metastasis via Wnt/β‐catenin activation.

PHGDH‐Mediated Serine Metabolism in Nucleus Pulposus Cells Is a Potential Therapeutic Target for Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
When nucleus pulposus cells senesce, PHGDH decreases, reducing serine synthesis and glutathione, impairing antioxidant capacity. The intermediate α‐KG also drops, lowering JMJD3 demethylase activity, increasing H3K27me3 at the Rap1b promoter, and reducing Rap1b expression, whose down‐regulation in turn activates mTORC1 and suppresses autophagy ...
